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 Ancient Murrelet colony locations to help inform the marine feature identified at the BCMCA Seabirds Workshop

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.

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 ANMU 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:

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.

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 Ancient Murrelet colony 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:

--> Reveiwed CDC dataset: Using select by attributes, selected all Ancient Murrelet features. Overlaid CWS, PC and CDC datasets and reviewed attributes. If a CWS point fell within a CDC polygon or was in close proximity, CWS/PC point was kept to represent the colony location in the final feature layer. **All CDC polygons were covered by the extent of above datasets. No CDC polygons were used in final feature layer creation.

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). For one record, a value existed for burrows instead of nest pairs and this value was used to assign the site to a relative importance class.

Attribute_Definition_Source: ESRI

Attribute_Domain_Values:

Unrepresentable_Domain: Positive real numbers that are automatically generated.

Attribute:

Attribute_Label: NestPairs

Attribute_Definition:

The number of pairs of nesting birds. Note: A value of 0 indicates that there were no birds of the particular species breeding in that particular year, but had been reported as breeding in previous surveys. If a species simply does not have an entry for a given survey year, then that species was not surveyed in that year (this does not, in any way, reflect the current status of that species in the given area). A value of 9999 is used to mean Not Applicable, that is when the number of birds is not reported as pairs, but rather as individuals (or in the case of Reef Island in 1985 and 1995, the value for ANMU is reported as the number of nesting burrows). In these cases, there will be a value in either the Individual or Burrows column. **Note: CWS estimated numbers are rounded off.**

Attribute:

Attribute_Label: ColSize

Attribute_Definition:

The size (in hectares) of the colonies for burrowing species (Storm Petrels, Cassin's Auklet, Rhinocerous Auklet, Ancient Murrelet, Tufted Puffin) where results were available. If results were not available, or where inapplicable, a size of 0 is given.

Attribute_Label: FEATURE

Attribute_Definition: Common name of the marine feature.

Attribute:

Attribute_Label: Burrows

Attribute_Definition:

For 1995, the estimate of the size of the Ancient Murrelet colony on Reef Island is given as the total number of Burrows estimated to be present in the colony. This is not directly comparable to the number of breeding pairs in the colony. A value of 9999 is used to mean Not Applicable; that is when the number of birds is not reported as Burrows, but rather as nesting pairs or individuals. In these cases, there will be a value in either the NestPairs or Individual column.

On a few of the islands along the B.C. coast, seabird nesting sites were located in several discrete locations. In these cases the main island is named first, followed by the specific location (eg. "(Kunghit Island) Annis Point" ).

Attribute:

Attribute_Label: Q

Attribute_Definition:

Parks Canada specific field: Quality codes for estimated number of pairs (1,2,3,4,5).
