Description:
Abstract:
The British Columbia Marine Conservation Analysis (BCMCA) is a collaborative project assembling and analyzing spatial information about Canada's Pacific Ocean. The overall goal of the BCMCA is to identify marine areas of high conservation value and marine areas important to human use. Results of the project are intended to inform and help advance marine planning initiatives in BC by providing collaborative, peer-reviewed scientific analyses based on the best ecological and human use spatial data at scales relevant to a BC coast-wide analysis.
Purpose:
The purpose of this dataset is to identify areal extents of Storm Petrel colony locations to help inform the marine feature identified at the BCMCA Seabirds Workshop. Data presented in 2x2 km planning units for MARXAN analysis.
Supplemental_Information:
This dataset is a compilation of data collected by many people, for different purposes, using different survey techniques with different methodologies within each technique and, therefore, considerable care must be taken when using the data, even for site-specific inquiries. Refer to the original metadata document for data limitations and usage. Title or link is provided within source information. Data was collected, merged and buffered by target feature layer using the following data sources: 1. CWS Seabird Colony data. 2. Parks Canada Nesting Seabird Colony data.

Canadian Wildlife Service (CWS). Dataset Name: Sites.shp. Includes the locations of all known seabird colonies. Points representing seabird colony locations were digitized using a 1:250000 basemap. Locations of all colonies were checked against 1:20000 TRIM and marine digital charts. Some of the colonies were shifted slightly to correspond to visible islands. Contains data from other sources with surveys conducted after 1989. Data sources include BCMOE, Parks Canada, Laskeek Bay Conservation Society and Bamfield Marine Station. Refer to original metadata document for data usage and limitations. Metadata document: bc_seabirdColonies_to_2007_updatedJune2008_meta.doc.

Source_Contribution:
CWS Marine Bird Areas of Interest. Dataset Name: CWS_Marine_Bird_Areas_of_Interest_May2007.shp. Dataset was only used where CWS and Parks Canada datasets lacked coverage. Combines data from other requested datasets: Coastal Water bird inventory, Moulting Seaducks, Seabird Ship Surveys, WVI Waterbird Survey, Great Blue Heron Colony datasets, Herring Spawn, Pelagic Seabird Survey, Seabird Colony Inventory. Many of the MBAOI's were chosen based upon an area's significant bird numbers, hence, dataset may not include full coverage of BCMCA marine target features. In most datasets, a buffer distance was determined and applied based on the species type or survey method. After buffering the data, a 1:20,000 TRIM shoreline was used to ERASE any portions that fell on land.

Process_Description:
--> Prepared CWS dataset:
Within SiteSurveys geodatabase table, selected by attributes all FTSP (Fork-tailed Storm Petrels), LSPE (Leach's Storm Petrels), STPE (Unidentified Storm Petrels) and exported into separate table. To maintain one-to-many relationship between spatial and aspatial, joined Sites spatial point layer to Storm Petrel table via GISkey field.
Process_Step:
Process_Description:
Displayed XY data using newly created X_COOR and Y_COORD fields and using PCS Albers as coordinate system imported from Sites.shp. Exported data into feature class. Added 3 new fields using Add Field tool: Feature, Data_Source, Dataset_ID. Populated fields using Calculate Field tool. Feature field calculated to equal the common name of the marine feature. Data_Source field calculated to equal the name of the dataset the data was derived from. Dataset_ID field calculated to equal the common dataset identifier as categorized by BCMCA.

Re-projected from PCS Albers to NAD 1983 BC Environment Albers using Project tool.
Process_Step:
Process_Description:
--> Prepared Parks Canada dataset:
**Tables within original geodatabase were corrupted. Created new "File" geodatabase NestingSeabirdColonies2. Exported (right click - export - to dbase (multiple) all geodatabase tables to new geodatabase.** Converted NestingSeabirdColonies shapefile to geodatabase feature class using feature class to feature class tool.
Process_Step:
Process_Description:
To maintain one-to-many relationship between spatial and aspatial, added 2 new fields to NestingSeabirdsColonies2 point feature class "X_COORD" and "Y_COORD" and calculated geometry. Joined spatial point layer to aspatial "Petrels" table using Site field. Displayed XY coordinates and exported data into feature class using NAD 1983 BC Environment Albers coordinate system.

Process_Step:
Process_Description:
Overlaid both Parks Canada and CWS colony data and reviewed each point. The following rules were used to create final feature layer: 1. If duplicate inventory years were recorded within CWS dataset, the point representing the most recent inventory year was kept. The same approach was used for the Parks Canada dataset. 2. If attributes (location, count and year) matched between CWS and Parks dataset, the CWS point was used and Parks points deleted. 3. In some cases, the most recent inventory date did not provide population estimates. In these cases, both inventory years were kept. This was generally found within Parks data. 4. In some cases, multiple points (CWS and Parks) were located on one island, attribute review revealed different count data. In these cases, PC points were deleted. 5. In some cases, the Parks data had the most recent inventory date. If the CWS attributes matched Parks, the most recent Parks inventory point was used to represent the seabird colony location and the CWS point was deleted. 6. In some cases, the CWS data summarized all Parks count data within small areas (i.e. Harrison Island) into one generalized point. In these cases, if the summed Parks count data matched CWS count data, the generalized CWS point was used to represent the seabird colony. Note: CWS metadata mentions NestPair estimated numbers are rounded off. In some cases, count attribute comparison between Parks and CWS data were slightly off due to rounding. In these cases, CWS point was kept. Both datasets contain source information in the table of attributes. For the CWS dataset, the source is listed as a number (DataRef field) and the metadata contains a listing of each source dataset by number. For the PC dataset, the source if written out in the file (Source field).
Process_Step:
Process_Description:
Merged CWS Seabird Colony and Parks Nesting Colony datasets using Merge tool to create one dataset storing all Storm Petrel Colony point data. During merge process like fields were combined using Field Map window to eliminate duplicate or redundant column headings. Field Map was also used to eliminate unnecessary fields not applicable for final feature layer requirements.
Process_Step:
Process_Description:
Buffered merged colony point data to 5000m (radius) using Buffer tool. This buffer distance follows the methodology used in the CWS Marine Birds Areas of Interest database.
Process_Step:
Process_Description:
--> Reviewed CWS Marine Bird Areas of Interest dataset:
Selected by attributes all records where DATASOURCE equaled Seabird Colony Inventory and species = FTSP or species = LSPE. Checked overlap with both Parks and CWS storm petrel colony locations. All features were duplicated - no MBAOI polygons were used to create feature.

Process_Description:
Colonies were grouped based on the site name and the count of nest pairs was summed when both of the storm petrel species (Leach's and Fork-tailed) were observed at the same colony. Relative Importance (RI) field created and populated based on the values in NestPairs. Highly Important = 3 (>5% of total BC population); Moderately Important = 2 (1-5% of total BC population); and Less Important = 1 (<1% of total BC population).
