INTRODUCTION

There are a number of marine topics covered by LRMPs ranging from commercial uses such as aquaculture and commercial fishing to the natural history and distribution of marine biota such as kelp beds and whales. The information that has been collected for the LRMPs is closely linked to the coastal areas where most of the vegetation, birds and marine mammals are concentrated and where most of the human use takes place. Corporate Information Services has been systematically assembling the following coastal inventories for the past 5 years. These form part of a corporate Coastal Resource Management System for Multiple Resource Management and Planning applications.

The commercial use topics and main sources of information for these topics are:

The natural history of the area is organized into a series of themes which map the known distribution of plants, fish, birds and marine mammals in the region. Where it is appropriate and also known, information on the abundance and seasonal use of the region has also been provided. The natural history themes and main source(s) of information for these themes include in the LRMPs are:

Inventory: Aquaculture Sites

1. CONTACT AGENCY

Ministry of Agriculture, Fisheries and Food, Barron Carswell, (250) 356-2237

2. DESCRIPTION OF INVENTORY

The inventory maintains information on finfish and shellfish leases, licenses and operation details. Sites which currently have a license to operate have been mapped using the legal boundaries of the site. Sites which have been proposed but not received a license have been mapped as points buffered with a 200m radius.

The information included in this inventory include: aquaculture license number; name of licensee and affiliated corporation; species farmed; type of culture method; details on the tenure (type, date of issue, expiry date, land file); the operational status of the operation; the number of years the operation has been in operation; the maximum capacity and production of the site; whether of not the site has been inspected my a MAFF officer; the relative importance of the site assigned by MAFF. Sites which have been proposed but not yet received a license have no information associated with them other than their location.

Most of the finfish aquaculture operations are rearing salmon while the majority of shellfish operations farm oysters. Other species which are of have been farmed in B.C. include clams, scallops, mussels, abalone, Nori, Kelp, and Black cod.

3. DATA COLLECTION METHODS

Information is collected on a site by site basis as an application for an aquaculture tenure is received. Each application contains a site map showing the proposed boundaries of the lease and a detailed description of the management plan including the species to be farmed, the size of the operation and the method that will be used to culture the species. The boundaries of the lease are mapped on 1:20,000 provincial map sheets and given legal descriptions by the Surveyor General Branch. The actual operation of the site is monitored by MAFF.

Sites proposed for operation, but which have not yet applied for tenure were identified by DFO fishery officers. Additional sites have been identified from nautical charts and sailing directions by the Ministry of Small Business, Culture and Tourism’s Central Coast Tourism Resource Inventory. The accuracy of the locations of these additional sites has not been verified.

Inventory: Finfish Capability

1. CONTACT AGENCY

Ministry of Agriculture, Food and Fisheries, Barron Carswell, 356-2237

2. DESCRIPTION OF INVENTORY

This inventory rates the biophysical capability of an area for net cage rearing of salmon as Good, Medium, Poor or Not Acceptable based on 16 biophysical variables. These include: Temperature, Salinity, Dissolved Oxygen, Currents, Hydrology, Waves, Substrate, Water Depth, Wind and Exposure, Shoreline Instability, Snowfall and Freeze over, Marine Vegetation, Freshwater Availability, Predators, Plankton Blooms, and Pollution.

3. DATA COLLECTION METHODS

Information was collected from personal interviews with local field officers from the Department of Fisheries and Oceans, Ministry of Forests, and the Ministry of Environment, Lands and Parks; interviews with specialist scientists; published information; and data on file in various government offices.

4. DATA DESCRIPTION

Coverage

Entire province except for areas where aquaculture is unlikely to expand due to current land use policies (unmapped areas include SE Vancouver Island, Strait of Juan de Fuca, Lower Mainland, Lasqueti Island, Texada Island and the Mainland coast to the NE of Texada Island)

Date inventory completed

1986-1996

Source data used for the ranking may date back over 100 years.

Collection scale

5. APPLICATION IN LRMP PROCESS

The inventory could help answer the following specific questions:

  • What is the capability of a specific region for salmon net pen rearing?
  • Where is the potential salmon net pen rearing areas?
  • How many good or medium sites in a region for salmon net pen rearing?

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

This scale is appropriate for regional planning but should not be used for evaluating individual sites or waterways.

Age of inventory: Are inventories up to date?

Partially

The inventory is really an assessment based on existing data and interviews with individuals. In many cases the existing biophysical data are old, however they still represent the current state of knowledge for the area. The criteria used to determine the capability for salmon net pen rearing are based on the tolerances of Chinook salmon and current net rearing technology. The technology has changed somewhat since the south coast evaluation was completed with more sturdy open water net cages now being available and other species being considered (e.g. Atlantic salmon, Sockeye).

Data coverage: Are data available for entire land base?

Yes

Entire province has been mapped except for areas where aquaculture is unlikely to expand due to current land use policies (SE Vancouver Island, Strait of Juan de Fuca, Lower Mainland, Lasqueti Island, Texada Island and the Mainland coast to the NE of Texada Island)

Data consistency: Are data comparable across the sub-region land base?

Partially

In the north coast region the newer technologies (other species, deep water nets) have been taken into consideration. While most of the province was mapped at a scale of 1:50,000, Johnstone Strait, Queen Charlotte Strait and the west coast of Vancouver Island were mapped at a scale of 1:125,000

Other comments:

In many areas the analysis of capability for salmon net pen rearing is based on incomplete information. For example in some areas there has never been a survey of water quality (temperature, salinity, dissolved oxygen) and the parameters have to be extrapolated from other regions. In a few areas such as parts of the Queen Charlotte Islands, even bathymetry data is lacking.

Inventory: Shellfish Capability

1. CONTACT AGENCY

Ministry of Agriculture, Food and Fisheries, Barron Carswell, (250) 356-2237

2. DESCRIPTION OF INVENTORY

The inventory rates the biophysical capability of an area for shellfish aquaculture. Each location where a survey has been made is marked as a point on the map. The location is assigned a rating for its capability for raising shellfish. The ratings (Good, Medium, Poor or Not Acceptable) are based on 14 physical and biological variables (e.g., temperature, salinity, diseases, predators).

3. DATA COLLECTION METHODS

Information for the nearshore salinity, temperature and beach slope and composition were collected from field surveys at sites that were no greater than 1.0 nautical mile (1.85 km) apart in most areas and no more than a half nautical mile apart in estuaries. The water temperature and salinity measurements were made at ½ meter intervals to a maximum depth of 50 meters. Temperature and salinity sampling at a location was made at least twice within a year; once during the summer and once in late winter or early spring. The beach profile and substrate was assessed during a single summer low-tide interval and the relative exposure was assessed once for each deep water reach and once for each beach area.

The inventory is designed so that the ratings can be updated as new information become available. For example, the initial rating may be based on just 10 of the 14 variables. This rating can be updated if information on the other variables is collected.

4. DATA DESCRIPTION

Coverage

Sampling and mapping are completed in the following areas: the major inlets on the west coast of Vancouver Island (Nootka, Quatsino, Kyuquot and Clayquot Sounds), Okover Inlet, Jervis Inlet, Quadra and Cortez, Johnstone Strait, the Broughton Archipelago and the south central coast waterways.

Date inventory completed

1997

Collection scale

The data were collected at a point location which has been mapped at a scale of 1:40,000.

5. APPLICATION IN LRMP PROCESS

The inventory could help answer the following specific questions:

  • What is the capability of a specific region for shellfish culture?
  • Where on the coast might shellfish culture occur?
  • How many good or medium sites for shellfish culture exit in a region?

The inventory could not help answer the following specific questions:

  • What is the capability of a specific site for shellfish culture?
  • What is the economic suitability of a site for shellfish culture?
  • Is shellfish culture economically viable in the region?

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

This scale is appropriate for regional planning but should not be used for evaluating individual sites or waterways.

Age of inventory: Are inventories up to date?

Yes

Data coverage: Are data available for entire land base?

Partially

Sampling and mapping are completed in the following areas: the major inlets on the west coast of Vancouver Island (Nootka, Quatsino, Kyuquot and Clayquot Sounds), Okover Inlet, Jervis Inlet, Quadra and Cortez, Johnstone Strait, the Broughton Archipelago and the south central coast waterways.

Data consistency: Are data comparable across the sub-region land base?

Yes

Other comments:

For waterways, the shellfish capability mapping provides information on the gross spatial delimitation of areas considered capable of sustaining shellfish culture, so they will not necessarily identify specific sites within these relatively large areas where shellfish culture facilities might ideally be located. For shellfish farming that could occur on beaches (e.g., oyster farming), specific beaches have been rated.

2. DESCRIPTION OF INVENTORY

Areas where commercial fishing takes place are indicated for commercial finfish and invertebrate fisheries. The commercial fisheries are divided into map layers according to species and/or gear product. They include:

  • Salmon troll fishery
  • Salmon net fisheries - includes both gillnet and seine fisheries
  • Herring fishery - includes commercial roe, spawn-on-kelp, bait and food fisheries
  • Groundfish fishery - includes troll, handline, long-line and trawl fisheries for numerous rockfish species, halibut, lingcod, gray cod, dogfish, hagfish, sablefish, hake, pollock and Pacific sandlance
  • Clam and Oyster fishery - includes Manila, Littleneck, Butter and Razor clams and Pacific oysters
  • Sea Urchin fishery- dive fishery for Red or Green sea urchin
  • Crab fishery - includes trap fisheries for Dungeness, red rock, Tanner crabs
  • Shrimp and Prawn fisheries - includes trap and/or trawl fisheries for shrimp and/or prawn
  • Miscellaneous shellfish fisheries - including scallop, gooseneck barnacle, octopus, squid

3. DATA COLLECTION METHODS

The information on the location and relative regional importance of a fishery are collected from interviews with field and scientific staff at the Department of Fisheries and Oceans (DFO) according to a standard data survey method developed by LUCO. The value of the catch are summarized by DFO major statistical area; There are 31 major inshore statistical areas and 17 major offshore statistical areas in B.C. The data on the landings are maintained by DFO and are based on landing slips provided by the fishery. There is some sampling done by DFO to check on the validity of these landing records. For the purpose of a LRMP the value of the landings are averaged for the last 5 year period for which they have been compiled.

4. DATA DESCRIPTION

5. APPLICATION IN LRMP PROCESS

The inventory could help answer the following specific questions:

  • Where does commercial fishing take place in the region?
  • What types of commercial fishing are currently occurring in the region?
  • What is the approximate value of commercial landings taken from an area?

The inventory should not be used to answer the following specific questions:

  • What is the potential for commercial fishing in an area? Commercial fishing may not take place due to current fisheries management strategies implemented by DFO. The are may be closed because of pollution, to rebuild stocks or the area may be allocated to recreational or aboriginal fisheries.
  • What was the historic importance of an area for commercial fishing?

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

Age of inventory: Are inventories up to date?

Yes

Data coverage: Are data available for entire land base?

Partially

The North coast and Queen Charlotte Islands regions are currently in the process of being collected and added in.

Data consistency: Are data comparable across the sub-region land base?

Partially

Not all fisheries exist in every region. Fisheries which are minor in a region may be lumped into a single data layer with “Other” fisheries in that region but be pulled out as a data layer on their own in regions where they are important.

Other comments:

The data reflect the DFO management strategies as much as they do the distributions of the species. There may be year to year changes as stock sizes change or allocations between different sectors and gear types are altered.

Inventory: Kelp Beds

1. CONTACT AGENCY

Ministry of Agriculture, Fisheries and Food, Barron Carswell, (250) 356-2237

Corporate Information Services, Carol Ogborne , (250) 356-6998

2. DESCRIPTION OF INVENTORY

The inventory contains information on the location, size and extent of kelp beds. In some areas there is information on the density and species of kelp present.

3. DATA COLLECTION METHODS

The data come from two sources. The main data source was the nautical charts and sailing guides published by the Canadian Hydrographic Service (CHS). While charting water depths and shorelines the CHS field officers also map kelp beds. They do not include information on the species of kelp or on the density of the bed. The second data source was kelp surveys done by the Ministry of Agriculture, Fisheries and Food (MAFF) using fixed wing aircraft. These surveys included field trips to the kelp beds to verify the kelp species and density of kelp observed from the air. These surveys were made only in a few selected areas of the province.

4. DATA DESCRIPTION

Coverage

LUCO has consolidated the information into a digital base for all of the South and Central coast regions. The North Coast and Queen Charlotte Islands regions are in the process of being compiled.

The entire province is covered by the CHS charts.

MAFF kelp surveys have been completed for Juan de Fuca Strait, Nootka Sound and the Hesquiat Peninsula, northern Vancouver Island, Hakai Passage to the Bardswell Group, Estevan Group and Campania Island, Goschen Island to Tree Nob Group, Malcolm Island, northwest Graham Island.

Date inventory completed

The LUCO database was completed for the Southern Georgia Strait in 1994 and is ongoing in the North Coast and Queen Charlotte Islands regions.

CHS chart data is collected on an ongoing basis.

The MAFF aerial kelp surveys were flown between 1974 and 1996.

Collection scale

The LUCO database was based on the:

-kelp data collected by CHS typically at a scale of 1:5000 to 1:50,000.

- MAFF kelp surveys collected at a scale of 1:7,200.

Presentation scale

The LUCO database is presented at a scale of 1:40,000.

  • Which areas are important as fish habitat?
  • Where could kelp harvesting take place?

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

Age of inventory: Are inventories up to date?

Partially

Kelp beds are dynamic and frequently change in response to grazing by sea urchins or damage by storms. In some areas the CHS charts are old and have little detail. The MAFF surveys are all pre-1990 except in the Hakai Passage region.

Data coverage: Are data available for entire land base?

Partially

Coverage for the North coast is not yet complete.

Data consistency: Are data comparable across the sub-region land base?

Partially

The data quality varies between areas depending on the availability of MAFF surveys and the age and scale of the CHS charts.

Other comments:

Kelp beds increase the local marine productivity. They are important habitats for many commercial species of fish and marine mammals, especially when they are young.

2. DESCRIPTION OF INVENTORY

The inventory maps the location and extent of eelgrass beds. The area and perimeter of the beds are calculated. The database also includes the name of the study from which the data were extracted.

3. DATA COLLECTION METHODS

The LUCO office has pulled together a variety of sources of data to map eelgrass beds. These include interpretation of satellite imagery to locate the larger beds and existing information extracted from interviews with fishery officers and other locals. In areas such as Johnstone Strait where eelgrass occurs in numerous small patches, it has not been mapped.

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

Age of inventory: Are inventories up to date?

Yes

Eelgrass beds may change their size or even disappear as a result of movement of coastal sediments. Most of the anecdotal information on the location of beds was collected at least 5 years ago.

Data coverage: Are data available for entire land base?

Partially

The LUCO database does not include information on the location of eelgrass beds in northern Johnstone Strait, Queen Charlotte Sound, or the mid-coast region. The collection of information for the Queen Charlotte Island and North coast regions in currently underway.

Data consistency: Are data comparable across the sub-region land base?

Partially

The larger eelgrass beds are more likely to be mapped than are the smaller beds. Beds in less remote areas are more likely to have been recorded by fishery officers.

Other comments:

Eelgrass beds increase the local marine productivity. They are important habitats for many commercial species of fish and shellfish, especially when they are young.

Inventory: Herring Spawn

1. CONTACT AGENCY

Department of Fisheries and Oceans, Bruce McCarter, (250) 756-7198

Corporate Information Services, Carol Ogborne , (250) 356-6998

2. DESCRIPTION OF INVENTORY

DFO maintains a database of all locations on the coast where herring spawn. Each location is identified as a 1 km coastal segment and includes information on the relative magnitude and the timing of herring spawn at that site. Any site where herring have been reported to spawn in since 1928 has been included. Sites with no known herring spawn are not included.

LUCO has converted the DFO herring spawn database into a GIS map layer. The LUCO maps are based on the same field data for the whole province but have been structured somewhat differently in the various regions of the province. In the Straits of Georgia and West Coast Vancouver Island regions the spawn has been mapped as linear coastal segments of varying length. Each segment is linked to a record in a database which provides information on: the DFO statistical section number; the first and last year for which spawning records are available; the consistency of spawning in that location (infrequent, constant or frequent), the magnitude of the spawn in that location (very small, small, medium, large, very large); the number of times in the last 50 years that spawn has been observed in that location (frequency of spawning); the linear length of the spawn; the area covered by the spawn; the average date of spawning both weighted to account for when most of the spawn was deposited and unweighted; and the relative importance of the spawn which is based on the magnitude of the spawn..

In the Johnstone Strait region and the coastal regions in northern B.C. the herring spawn GIS map layer was based on 1 km coastal segments to which were attached information on the frequency of all spawning recorded since 1928, the mean Julian day of the start of the spawning event, the estimated mean number of egg layers weighted by the percent cover of the are by spawn, the area covered by the spawn, and a “Spawn Index”. The Spawn Index is a measure of the relative abundance of spawn within that 1 km coastal segment and is based on the total number of eggs estimated to be there. The relative importance of the spawn was assigned based on the Spawn Index. Adjacent coastal segments with a similar Spawn Index were joined together.

3. DATA COLLECTION METHODS

The information on herring spawn has been collected mainly by fishery officers observing the spawn from the shore. In a few locations there have been extensive dive surveys to map the magnitude and location of the spawn deposition. DFO maintains a database of the location of spawn which is augmented every year with new data from fishery officers.

4. DATA DESCRIPTION

Coverage

DFO maintains information for the entire province.

The GIS database for the North Coast and Queen Charlotte Island regions is currently being created. It is complete for the rest of the province.

5. APPLICATION IN LRMP PROCESS

The inventory could help answer the following specific questions:

  • What is the relative importance of a coastal area to B.C. herring stocks?
  • What resources would be impacted by coastal development or pollution?

The inventory could not help answer the following specific questions:

· Will herring spawn in a certain location this year?

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

The herring spawn is variable enough that data collected at a scale larger than 1:1,000,000 would be assuming more accuracy than existed.

Age of inventory: Are inventories up to date?

Yes

The GIS maps maintained by LUCO will become outdated soon, however they represent long term trends and the DFO database is kept current.

Data coverage: Are data available for entire land base?

Yes

The DFO database is maintained for the entire province. The LUCO GIS maps are complete except for the North Coast and Queen Charlotte Islands regions which will be completed this year.

Data consistency: Are data comparable across the sub-region land base?

Yes

Other comments:

Small isolated stocks may have a low spawn index but are possibly important in maintaining biodiversity and resilience of the B.C. herring to climate change.

Inventory: Cetaceans

1. CONTACT AGENCY

Department of Fisheries and Oceans, Graeme Ellis, (250) 756-7245

Corporate Information Services, Carol Ogborne , (250) 356-6998

2. DESCRIPTION OF INVENTORY

The inventory maps the distribution and relative importance of coast areas of B.C. to the major cetacean species found in B.C. waters. The inventory individually maps Orcas (Killer whales), Gray whales, Humpback whales, Dall’s porpoise, Harbour porpoise, and Minke whale. Not all species are mapped for all regions of the province. A species is mapped only in those regions where they are reasonable common. The inventory maps the distribution and relative abundance (high, medium, low) of the species in an area.

3. DATA COLLECTION METHODS

The distribution and abundance of the individual whale or porpoise species were mapped from information collected from discussions with marine mammal experts. In some instances the actual relative abundance of a species was known for an area; in more remote areas the abundance was predicted using the known range of the species and the preference of the species for particular water depths and the distance from shore that it is typically found.

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

Age of inventory: Are inventories up to dte?

Yes

There has been little in the way of systematic surveys for cetaceans since the LUCO maps were created. Additional sighting data is constantly being gathered but the maps of general abundance are unlikely to change frequently.

Data coverage: Are data available for entire land base?

Partially

The North Coast and Queen Charlotte Islands regions are in the process of being compiled.

Data consistency: Are data comparable across the sub-region land base?

Yes

There has been little systematic mapping of cetacean distributions in B.C. aside from the LUCO mapping. There are standards for recording of sighting data, however non-experts frequently misidentify species and sighting are primarily in areas where the population is concentrated such as the Straits of Georgia of Johnstone Strait.

Other comments:

Cetaceans are highly mobile species and may be found almost anywhere in the region. The LUCO maps only map the areas where they are most likely to occur. Our knowledge of the distribution and habitat preferences of cetaceans is still very incomplete.

Inventory: Seals and Sea Lions

1. CONTACT AGENCY

Department of Fisheries and Oceans, Peter Olesiuk, (250) 756-7254

Corporate Information Services, Carol Ogborne , (250) 356-6998

2. DESCRIPTION OF INVENTORY

The inventory maps the location of haulouts and rafting or milling sites for Harbour seals, Elephant seals, Steller sea lions, and California sea lions. Each site is identified and the number of animals is recorded. Harbour seals are identified as either ‘pups’ (born that year) or adults. Sea lions are identified as being adult male or female or ‘pups’.

3. DATA COLLECTION METHODS

The scientists at DFO use fixed winged aircraft to fly the coast at low tide and count the number of seals or sea lions at each site. At sites where there are large numbers of individuals, photographs are taken and the number of seals or sea lions are counted from the photos back in the laboratory. Harbour seals are typically counted during the late spring or summer . Sea lions are counted both during the winter (typically February) and again during the summer. This is because the California sea lions typically are found in B.C. waters only during the winter months. There are no systematic surveys for Elephant seals which are not common in B.C.

4. DATA DESCRIPTION

Coverage

Entire province

Certain regions have been more intensively and/or frequently surveyed than others. There have been no systematic surveys in most of the Central coast region and outside the Skeena River in the North Coast region.

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

Age of inventory: Are inventories up to date?

Yes

Data coverage: Are data available for entire land base?

Partially

DFO has surveyed the Strait of Georgia, Juan de Fuca Strait , Barkley Sound , NE Vancouver Island, the Skeena River area and the east coast of the Queen Charlotte Islands

Data consistency: Are data comparable across the sub-region land base?

Yes

The frequency of surveys has been greatest in the Strait of Georgia, especially around the Fraser River and Boundary Bay.

Other comments:

Seals are only surveyed during the summer months, however it is assumed that their winter distribution is similar. The seal population is increasing at a rate of more than 15% and so it is expected that new haulouts will constantly be appearing. The range of the California sea lion has gradually be moving northward and these sea lions are now sighted as far north as Barley Sound or Johnstone Strait. The Steller sea lion breeds in B.C. and is found throughout the province.

Inventory: Sea Otters

1. CONTACT AGENCY

Department of Fisheries and Oceans, Graeme Ellis, (250) 756-7245

Corporate Information Services, Carol Ogborne , (250) 356-6998

2. DESCRIPTION OF INVENTORY

The inventory maps locations where sea otters are know to occur.

3. DATA COLLECTION METHODS

The locations where sea otters are currently known to occur have been mapped from discussions with experts at the Department of Fisheries and Oceans. DFO receives information on where sea otters have been sighted from local DFO or provincial government field workers. The marine Mammal unit at DFO then surveys the extent of sea otters in the area from helicopters, fixed winged aircraft or by boat. The provincial Corporate Information Services then gets the information on the general extent of sea otters and maps it using the GIS.

Inventory: Coastal Sea birds

1. CONTACT AGENCY

Corporate Information Services, Don Howes - (250) 356-7721

Canadian Wildlife Service, Michael Dunn - (604) 940 4660

2. DESCRIPTION OF INVENTORY

The inventory is assembled from multiple sources and maps areas where coastal marine birds concentrate or breed on the B.C. coast. The birds have been separated into waterfowl, shorebirds, Marbled murrelets, other “Alcids”, gulls, cormorants and “pelagic” bird species which are associated with the open ocean. The locations where sea bird species breed are included in the maps.

"Waterfowl" breed primarily in interior regions and utilize coastal locations during spring or fall migrations or for the entire non-breeding period from September to mid-May. Three species of diving ducks, Harlequin ducks, Surf scoters and White-winged scoters may move to marine waters during the late summer (July-August) during their annual post-breeding moult. During the summer loons may use the marine coastal waters and dabbling ducks, geese and swans can be found in marine estuaries near breeding sites.

Most shorebirds are migrants or winter visitors to the coastal areas of British Columbia. The only shorebirds which nests on the B.C. coast are the Black Oystercatcher and Great Blue Heron. The shorebirds regularily found in B.C. group include on or more species of Plovers, surfbirds, Turnstones, and Sandpipers all of which are found primarily along the shoreline. While Phalaropes are also classified as shorebirds by taxonomists, the three Phalarope species found on the BC coast have been treated as pelagic birds as in B.C. waters they are usually found migrating in large flocks offshore. On the other hand, the Great Blue heron, is not scientifically classified as a shorebird but has been lumped in with the shorebirds because of its similar use of habitat and rare occurrence.

Marbled murrelets are on the provincial 'Blue' list of species which are considered vulnerable and are thought to be candidates for the 'Red' list of endangered species in the foreseeable future. While the B.C. population still numbers in the thousands, evidence indicates that the murrelet numbers are declining. During the breeding season (April-August), the majority of murrelets are found offshore of old-growth forests, located mostly within 60 km of the coast. At sea, murrelets are usually found as widely spaced pairs but occasionally form large flocks which may contain sizeable portions of local populations. Often these flocks are associated with tidal rips, high current areas or river plumes. While small numbers of murrelets may winter in most coastal waters of B.C., selected parts of the Strait of Georgia, southern Johnstone Strait and Puget Sound are the primary wintering areas of murrelets in British Columbia.

The group of birds refered to as “Other Alcids” includes murres, murrelets, guillimots and aukletts which are diving sea birds which mostly tend to nest in large colonies on offshore islands. There are 3 common species of gulls on the B.C. coast (only one species breeds here), and three species of cormorants. The offshore or “pelagic” marine birds include Phalaropes, Shearwaters, Petrels, and Albatross.

Fifteen species of marine bird breed in marine areas on the B.C. coast. These include Least and Fork-tailed Storm petrels; Glaucous-winged gull; Pelagic, Brandt’s and Double-crested cormorants; Common Murre; Pigeon Guillemot; Cassin and Rhinoceros auklets; Tufted and Horned Puffins; Black oystercatcher; and Great Blue Heron. The point location of the nest or colony and the most current estimate of the number of breeding birds is given for each site.

3. DATA COLLECTION METHODS

The main source of data on species distributions came from a database of bird sightings made during aerial surveys conducted primarily between 1967 and 1982. Some additional sites were mapped based on more recent published surveys or from personal cummunications with experts. The number and location of sea bird colonies or nests has been published by the Canadian Wildlife Service. These information were entered into a GIS database by LUCO.

5. APPLICATION IN LRMP PROCESS

The inventory could help answer the following specific questions:

  • Where do marine birds breed in the region?
  • Where and in what season have major concentrations of marine birds been seen in the region?

The inventory could not help answer the following specific questions:

  • How many marine birds are there in the region?
  • Where are all of the areas important to marine birds in the region?

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

Birds are highly mobile and mapping their distribution at a finer scale would apply more knowledge than we have at a regional level.

Age of inventory: Are inventories up to date?

Partially

The maps produced by LUCO for the LRMP are recent and based on the best possible knowledge at this time. Much of the underlying information however is out of date especially in the more remote areas such as the Central coast region.

Data coverage: Are data available for entire land base?

Partially

There have been surveys in all parts of the province but not all areas within those regions have been surveyed.

Data consistency: Are data comparable across the sub-region land base?

Partially

The amount of information around estuaries is generally higher than that for other areas. The inventories for bird colonies have been fairly consistent throughout the province.

Other comments:

The database only shows where concentrations of marine birds have been observed. There are many areas of the province with few or no surveys or surveys that are over 20 years old.

Inventory: Bald Eagles

1. CONTACT AGENCY

Corporate Information Services, Carol Ogborne , (250) 356-6998

Ministry of Environment, Lands and Parks, Doug Janz (250) 751-3217

2. DESCRIPTION OF INVENTORY

In Johnstone Strait and the Central coast regions, the inventory identifies the relative density of Bald eagles nests along the B.C. coast. In the Strait of Georgia and the west coast of Vancouver Island the relative abundance of Bald eagles was mapped based on the concensus of regional experts. The North Coast and Queen Charlotte Islands regions are currently being mapped in a manner similar to that done in Johnstone Strait and the Central Coast regions.

Bald eagles are found throughout the province, mostly near the water. Eagles are found on the coast all year. In spring bald eagles move back to their nest sites in mid-to-late February. In summer, aggregations occur only along the coast where "herring ball" and surface-feeding fishes attract both breeding and non-breeding eagles. Eagles also concentrate during the spring in areas of significant herring spawn and in the fall and winter eagles move into estuaries and rivers to feed on spent carcasses of spawning salmon.

3. DATA COLLECTION METHODS

Bald eagles are generally surveyed by the Ministry of Environment, Lands and Parks (MELP) during the late spring-early summer while they are nesting. The surveys are made using either fixed wing aircraft or helicopters flying low along the coast. When a nest is sighted the observers fly around until they determnine if it is occupied or not. Nests in the Strait of Georgia are survyed most years; areas in more remote areas are survyed less frequently or not at all.

While there has been considerable survey effort on the B.C. coast directed towards mapping the location of Bald eagle nest sites, outside of the breeding season there have been no systematic surveys of bald eagle abundance or distribution in the study area. Midwinter bald eagle surveys have been organized by MELP however the surveys are dependent on volunteers and the coverage outside of the Straits of Georgia is poor.

In the Johnstone Strait and north coast regions, the point locations of occupied eagles nests were converted to maps of nest density (#/km²) in areas where the coast had all been survyed. In areas where only a few surveyes had been made, the coast was divided into areas of similar eagle “habitat” and the desities in the areas which had been surveyed were applied to all areas of similar habitat.

In the Strait of Georgia and the West Coast of Vancouver Island regions experts were asked to identify the relative abundance of Bald eagles in defined regions of the coast which were thought to have relatively homogeneous concentrations of birds. The coastal habitat type predominant in the area was also taken into consideration in assigning the abundance of the eagles to that area.

The inventory could help answer the following specific questions:

  • Where are the areas where Bald eagle nests tend to be concentrated in the region?

The inventory could not help answer the following specific questions:

  • Is there a Bald eagle nest present at this site?
  • How many Bald eagles are there in the region?

6. INVENTORY RELIABILITY FOR LRMP

Scale: Is the inventory an appropriate scale for LRMPs?

Yes

Age of inventory: Are inventories up to date?

Yes

Where they exist the surveys are fairly current. Eagles often have more than one nest site in their territories and do not always use the same site each year.

Data coverage: Are data available for entire land base?

Partially

In areas where there have not been Bald eagle surveys the density of nests has been extrapolated.

Data consistency: Are data comparable across the sub-region land base?

Partially

A region may include areas where the density of eagle nests has been determined from actual nest surveys and areas where the density is only estimated. The Straits of Georgia and West Coast of Vancouver Island regions were assessed differently from the other regions.

Inventory: BC Ferry Terminals and Routes

1. CONTACT AGENCY

Corporate Information Services, Carol Ogborne , (250) 356-6998

BC Ferry Corporation, Planning Dept., Ross Harris

2. DESCRIPTION OF INVENTORY

The inventory maps the location of BC Ferry terminals, major ferry wharves and official BC ferry routes. All terminals were mapped as points with information on the name of the location and associated number of berths. Wharves were mapped as lines showing their location and length and official routes were mapped with the associated traffic volumes. Traffic volumes included information on the number of passengers, buses, trucks, overheight vehicles and underheight vehicles for the last fiscal year. The number of passengers was broken down to the number by month. Traffic was not available for all routes. As traffic is assigned to a route it does not provide an indication of the traffic volume at an individual berth.

3. DATA COLLECTION METHODS

The locations of ferry routes, berths and wharves was taken from 1:50,000 NTS maps and/or CHS charts. Operational data was supplied by BC Ferry Corporation and linked to the berths or routes in the GIS.
