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 socio-economic spatial data at scales relevant to a BC coast-wide analysis.

Purpose:

The purpose of this dataset is to identify areal extents of Tokidaea chilkatensis presence that helps inform the marine feature identified at the BCMCA Marine Plants 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 and merged by target feature layer using the following data sources: 1. CDC. Identifies species as element occurrence's.

CDC Algae data. Dataset name: alga_eos.shp. Mapped areas of land/water (Element Occurrence) in which a species (algae) or ecological community is, or was, present and provincial ranking applied. The CDC follows NatureServe mapping methodolgy whereby Element Occurances are depicted as polygons. Locations are supplied via lat/long coordinates, and bufferred according to locational uncertainties. Includes rare algae names for 50 species short listed. Original metadata document: Online <http://www.env.gov.bc.ca/cdc/gis/eo_data_fields_06.htm>

Source_Information:

Source_Contribution:

UBC Herbarium (Algae Export). Raw data: Algae_Export.xls. Each recorded specimens represents sample collected within UBC Herbarium. Database contains 50 records for Postelsia palmaeformis, 104 records for Pterygophora californica, and 230 records for all other features. Only online reference index: <http://www.botany.ubc.ca/herbarium/algae/index.html>

Process_Step:

Process_Description:

--> To prepare CDC dataset:
Re-projected CDC's alga_eos.shp from an Unknown Coordinate System to NAD 1983 BC Environment Albers imported from CMN's BS_EG95.shp. Converted shapefile to feature class using feature class to feature class tool. Selected from CDC_algae_eos.shp all marine target features identified in Plants workshop and exported into separate feature classes. Using ArcMap, all records applicable to workshop target species were selected in the attributes table, exported into a feature class, and stored within the Algae Geodatabase.

\\CRMLTD03\E$\F\Crm1143\Source\080818_SourceDocs\Original_Data\Plants\BCMCA_Plants.gdb

Process_Step:

Process_Description:

Added 3 fields to CDC feature layers: Feature (common name of marine feature identified), SOURCE_DATA (dataset shapefile name), Dataset_ID (dataset common identifier as per BCMCA dataset DB notes)
To add fields, used the add field tool in batch mode (right click tool in toolbox and select batch) to update all feature classes at once. Click and drag each feature into the batch field window to populate one row for each feature. To set each feature classes' tool parameters, scroll to the right in the table.

Process_Step:

Process_Description:

Populated the fields using the calculate field tool in batch mode. Feature fields were calculated to equal the "SNAME" column. SOURCE_DATA fields were calculated to equal the name of the shapefile or feature class that the data was derived from. Dataset_ID fields were calculated to equal the common dataset identifier as categorized by BCMCA.

Process_Step:

Process_Description:

--> To prepare UBC dataset:
Converted UBC Algae Export.xls table into dbase format so that the XY coordinates stored in the records could be plotted spatially and exported as point feature classes.
There was one Tokidaea chilkatensis record identified within the UBC Algae Export.xls table. There was no coordinate information supplied to plot point, therefore, it was not included in the final feature layer.
