Our report on a series of Marxan scenarios is available to download: BCMCA: A Series of Marxan Scenarios for Pacific Canada (10 MB PDF). The report describes how Marxan works and details the methods that BCMCA used:
- to identify potential areas of high conservation value (using ecological data only).
- to identify areas important to human use (using human use data only).
The report presents the ecological scenario results and includes 18 results maps for 6 different ecological scenarios, illustrating potential areas of high conservation value. In addition, the report presents human use scenario results, along with 10 results maps for commercial fisheries and shipping and transportation, illustrating areas important to those sectors in the marine environment. The remaining four sectors (recreational fisheries, ocean energy, tourism and recreation, and tenures) requested that the Marxan results not be made public. Further information is provided on page 46 of the report.
downloadable ecological Marxan scenario results
Click on the links below to download the data showing the results of the ecological Marxan scenarios. Each set of results includes three shapefiles, one for each of level of clumping (i.e., no clumping, medium clumping, and high clumping) for that target level:
- Expert low targets (19.8 MB)
- Expert medium targets (22.7 MB)
- Expert high targets (24.4 MB)
- Project Team low targets (20.7 MB)
- Project Team medium targets (22.9 MB)
- Project Team high targets (23.8 MB)
downloadable human use Marxan scenario results
Click on the links below to download the data showing the results of the human use Marxan scenarios for commercial fisheries and shipping and transportation. Each set of results includes five shapefiles, one for each target level:
We also prepared an animation series of the ecological Marxan results to show how the spatial arrangement of solutions shifts as targets change or as the level of clumping changes. Read the report then check out these animated maps and watch what happened to scenario results when:
We used different levels of expert recommended targets (low-med-high) and kept clump size medium.
We used different levels of Project Team recommended targets (low-med-high) and kept clump size medium.
We used medium expert recommended targets, but varied the clump size in the results.
We used medium Project Team recommended targets, but varied the clump size in the results.
