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 priority eelgrass habitat to help inform the marine feature identified at the BCMCA Marine Plants workshop. Data presented as 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 pasted within source information for data limitations and usage. Data was collected, merged, and dissolved by species using the following data sources: 1. Provincial (LUCO) kelp polygons based on aerial overflights and CHS chart data. 2. DFO Quatsino Sound Eelgrass data. 3. Parks Canada Pacific Rim raster and eelgrass polygon data. 4.

Parks Canada Pacific Rim raster data. Dataset Name: zoma_pp. Eelgrass confidence weighted abundance raster. Metadata report: The cell values of each confidence weighted abundance raster range from some negative extreme (representing areas that we are confident the species is absent) to zero (representing areas for which we have no good basis for judgment of relative abundance i.e. data sources conflict and/or we have no data for the area) to some extreme positive value (representing areas that we are confident have high abundance of the species). Intermediate negative and positive values represent an index (product) of our confidence in the data source and relative abundance.
Some known false values exist (in particular values in the vicinity of 329086E,5417687N (UTM10, Nad83) are erroneous and should be set to zero as they are associated with an input data point with incorrect coordinates).

Prepared Provincial Kelp dataset: Defined and projected from an Unknown Coordinate System to NAD 1983 Albers imported from LOS's kelp_bc_merge8 dataset using the Define Projection tool. Converted coverage to feature class using feature class to feature class tool. Note: Original coverage had an undefined coordinate system. Metadata review revealed a projection was previously assigned but was not defined. To determine projection, tested alignment with a known coastline dataset with BC Albers projection. Prov kelp dataset aligned well with data. Hence, NAD 1983 Albers projection was assumed and used to define the projection. Re-projected from Nad 1983 Albers to NAD 1983 BC Environment Albers using Project tool.

Prepared CMN SC_Eelgrass_Beds.shp:** XY coordinate system defines a NAD 1927 datum. To overlay with all other data, dataset needed a datum transformation. A test was done transforming NAD 1927 to NAD 1983 using NTv2_Canada. Once the datum transformation was applied, the data was shifted substantially resulting in overland alignment. To determine if data may have originally been defined incorrectly, a second test was done re-defining the projection from NAD 1927 UTM Zone 10N to NAD 1983 UTM Zone 10N using the Define projection tool. In several test locations, the NAD 1983 data had better alignment with the coastline than the NAD 1927 data. Thus, dataset with NAD 1983 UTM Zone 10N was used to create final feature layer.** Re-Defined projection from NAD 1927 UTM Zone 10N to NAD 1983 UTM Zone 10N using the Define Projection tool. Projected to NAD 1983 BC Environment Albers using Project tool. Converted shapefile to feature class using feature class to feature class tool.

Process_Description:
The final BMCA eelgrass polygon feature class was overlaid with the final features for Great Blue Heron Nest Sites (Shorebird feature), Brant Goose (Nearshore Bird feature) and the high value planning units (classes 1 to 3) from the Herring Spawn feature (Pelagic Bird/Fish feature) using 'select by location' and the option to 'add to the currently selected features in...'. The resulting polygons were then exported to a new feature class. These features had been identified in the workshop report to help identify priority eelgrass habitats.
Note: The eelgrass polygons (representing eelgrass beds) were not clipped to the features with which they were overlaid.
