A series of maps compare the 1800, 1938 and 2005 ecosystems in the Okanagan and Lower Similkameen Valleys. Much of the gentle slope valley bottom ecosystems have been replaced by
urban and agricultural development. Analysis of the areal extent of historical and remaining areas has been done for specific ecosystem types that are important for many species at risk and are
themselves ecosystems at risk.

The historical ecosystem mapping was done on 1:12,000 scale 1938 air photographs, that were extrapolated back to 1800 ecosystems using ecological attributes, following the Terrestrial
Ecosystem Mapping (TEM) methodology (Ecosystems Working Group, 1998). The south Okanagan and Similkameen Valleys were mapped in 2001 and 2002. Mapping for 2005 was extracted
from recent (TEM) and 2001 - 2004 orthophotos at a scale of 1:20,000. The Central and North Okanagan areas were begun in 2005 and completed in 2007.
Power Point presentation of Pre-Historical Pre-European Settlement in the Okanagan is also included.
