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 incorporate all near shore data identifying Marbled Murrelet winter sites (December, January), process and summarize weighted densities by BCMCA planning unit to help inform the marine feature identified at the BCMCA Seabirds Workshop. Data presented as 2 km x 2 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.

Bird Studies Canada (BSC) BC Coastal Waterbirds Survey. Dataset name: BCCWS_polygons.shp. Metadata document: Coastal Waterbird Survey summary metadata March 2007.doc. Volunteer-based monitoring program for coastal waterbirds started in September 1999. The monthly surveys are shoreline-based for the period of September through April. Observers undertake surveys at sites with clearly defined boundaries once per month from September through April, and identify and count all coastal waterbirds with binoculars and/or spotting scope. Purpose is to obtain a relative index of coastal waterbird populations and information on the distribution and ecology of wintering coastal waterbirds in BC. Dataset supplied includes spatial layer. All bird occurrences and counts stored in a raw data format and included within excel spreadsheet; approx 75,000 records. Bird occurrences are documented by site location, rather than individual sighting locations and can be joined to spatial polygon data via SiteCode. Refer to original metadata document (listed above) for more information regarding survey background, methodology and data limitations.

>Prepared BC Coastal Waterbirds Survey dataset:
Imported excel worksheets "BCCWS raw data 1, raw data 2, raw data 3" from Coastal Waterbird Survey data '99-'08.xls into a geodatabase. To join tables to spatial, created new field, SITECODE, in all 3 tables. Using field calculator, populated SITECODE field with following formula: [RegionCode]& [SiteNumber]. Create one field storing date (ymd) rather than 3 fields. Populated field using field calculator with the following formula: [Year_]&"/"& [Month_]&"/"& [Day_]. To combine all 3 tables into one table, used the Append tool and appended raw data 2 and raw data 3 to raw data 1 table. Deleted "Year_" Month_" and "Day_" fields using Delete Field tool. 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 SpeciesCode field. Standardized the Feature field naming convention to equal the common name of the marine species rather than the abbreviated species code. Data_Source field calculated to equal the name of the dataset from which data was derived. Dataset_ID field calculated to equal the common dataset identifier as categorized by BCMCA.

Process_Description:
Re-projected spatial layer from NAD 1983 Albers to NAD 1983 BC Environment Albers using Project tool. All polygons with the same Sitecode were merged so that there were no duplications in the Sitecode field. To ensure areas matched in both the spatial and the survey data, the total shape area in the spatial was summed where duplicate Sitecodes and cross-checked with area recorded in corresponding SiteCode records in raw excel data. Once the areas were verified, duplicate polygons were merged using merge operation (Advanced Editor toolbar) into one and Name field updated to reflect entire survey location. Duplicate SiteCode records were found in GIMA1 (3 records), GIMA2 (4 records), GISE1 (2 records), and QCMA4 (2 records).
Process_Step:
Process_Description:
Using MS Access query, selected all records within raw data table where SpeciesCode = 'MAMU' with survey months >11 or <2. Exported selected species' records into a feature table. To calculate the total number of surveys, two queries were created using Microsoft Access. The first query was created to record all instances of survey dates meeting the features' winter specifications within each survey polygon (i.e. each date instance was assigned a value of 1), grouped and ordered by polygon. To eliminate duplicate counts (i.e. each species recorded has a survey date), only the first date instance was assigned a value of one. The second query was created to count and sum all date instances within each grouped polygon.
Process_Step:
Process_Description:
For each SiteCode, summarized feature table to get the average bird counts. Include the number of surveys in which the species was sighted and the total number of survey tables. Joined feature table to spatial using SiteCode field and exported into separate feature classes. Added a new field, Season, and calculated to equal the season in which the feature is identified as specified by BCMCA. Note: a few records in the aspatial table did not have matching SiteCodes within the spatial layer. Deleted all unnecessary fields using Delete Fields tool.

Process_Description:
Re-projected cwi_bc.shp from PCS Albers to NAD 1983 BC Environment Albers using Project tool. Related 2 survey tables (cwilut_bc/cwidat_bc) to spatial, and extracted all spatial lines correlating to target feature into a separate feature class. Reviewed Digitized field and where "F2", spatial lines were merged according to each unique combination of SHOREUNITS2 field to create a one-to-one relationship with the survey data. New fields were created (UNIQUEID, NEWID) in order to provide a link to the corresponding survey data. Where applicable, all null and non-spatially linked shoreunits in the feature tables were deleted in order to maintain the same record count in both the spatial and table (refer to associated text file listing null and non-spatially linked records). Joined cwidat_bc feature table to spatial layer using NEWID field and exported to a feature class. Added 5 new fields using Add Field tool: Season, Feature, DATA_SOURCE, Dataset_ID and Buffer_m. Populated fields using Calculate Field tool. Season field calculated to equal the season in which the feature is identified as specified by BCMCA. Feature field calculated to equal common name of the marine feature as identified within the COMNAME field. DATA_SOURCE calculated to equal the name of the dataset from which data was derived. Dataset_ID field calculated to equal the common dataset identifier as categorized by BCMCA. Buffer field calculated based on Survey_Method used: 50m radius (ground, air, and unknown surveys), 150m radius (boat surveys). Buffered shorelines using Buffer tool based on Buffer field. Deleted un-necessary fields using Delete Field tool.

<<Prepared BC Ferry dataset: Added a new field within the Survey_data table to store the date (within first 6 digits of Transect_ID field) and calculated to read yyyy/mm/dd format. Selected all records within Survey_data where [MAMU] > 0, and survey months >11 or <3. Species' records meeting the criteria were exported into a feature table. To calculate the total number of surveys, two queries were created using Microsoft Access. The first query was created to record all instances of survey dates meeting the features' winter specifications within each segment (i.e. each date instance was assigned a value of 1), and then grouped and ordered by Segment_ID. To eliminate duplicate counts (i.e. each species recorded has a survey date), only the first date instance was assigned a value of one. The second query was created to count and sum all date instances within each grouped Segment. A similar query to the above was used to calculate the surveys in which species were sighted. Data was recorded in various time intervals along a segment on a given survey date. In these cases, only the first unique survey date was given a count value of one to avoid redundant survey counts and for consistency with the total surveys count.
Process_Step:
Process_Description:
For each Segment_ID, summarized feature table by average bird counts. Included the number of surveys in which the species was sighted and the total number of survey tables. Added 4 fields using Add Field tool: Season, Feature, Data_Source, Dataset_ID. Populated fields using Calculate Field tool. Season field calculated to equal the season in which the feature is identified as specified by BCMCA. Feature field calculated to equal the common name of the marine species as identified within species code attribute. Data_Source field calculated to equal the name of the dataset from which the data was derived. Dataset_ID field calculated to equal the common dataset identifier as categorized by BCMCA. Joined feature table to spatial layer using Segment_ID field in the table and Segment field in the spatial and exported into a feature class.

>Created Marxan File:
Reviewed the distribution of the data in the final processed file using 5 quantiles as defined by BCMCA. Deleted the planning units with average densities that fell within the bottom quantile. Species was used to create the at-sea density feature. To avoid double representation, overlaid feature with at_sea_density.shp and deleted planning units from the marxan file that were identical to those planning units with densities greater than zero in the at sea density feature.
Process_Step:
Process_Description:
The distribution of average density values across the BCMCA planning units was examined for normality and it was found to be skewed (i.e., there were a few very large values which would have biased Marxan toward choosing these planning units to meet any target set). To account for this, the density values were transformed using a natural log function to normalize the data. Then the transformed values were shifted (if below zero) such that the lowest value was equal to 1 (i.e., a positive constant was added to each value). The values in the [Transform_Density] field are the result of this transformation and the distribution of these values across the planning units is near-normal.
