Ecosystem mapping was completed for the forested portion of TFL 45 in 2000. Major excluded areas included parkland, alpine, glaciers, extensive avalanche tracks, and sparsely vegetated outwash plains, deglaciated moraines, and rock. Included in this are small, isolated patches of forested ecosystems. The objective of this project is to extend ecosystem mapping into the existing unmapped area to provide complete coverage of the TFL. Given the nature of ecosystems to be mapped, and our experience in completing TEM mapping for the rest of the TFL, this project will be completed through air photo interpretation. To maximize efficiency, an innovative method will be employed which utilizes existing forest cover spatial data as much as possible. The final product will meet applicable TEM data standards and will be compatible with the existing TEM database.
