Update to the original South Okanagan Biophysical Mapping to the 1998 Standard for Terrestrial Ecosystem Mapping in BC. The study area is coincident with the original mapping except for gaps between the South Okanagan TEM and TFL15 TEM which were added in 2006. The updates include BEC classification (not finalized at time of reporting), BGC zone and subzone boundaries, Ecosections, and ecosystem units including where recent burns and development have occurred. An SEI theme is included.

In 1991-1994 the south Okanagan and lower Similkameen Valleys were mapped using a biophysical habitat mapping approach on 1:15,000 aerial photographs taken in the mid 1980s (Lea et al. 1991; Harper et al. 1996). Since that time, a provincial ecosystem mapping standard has been adopted and the classification of ecosystems has been updated and revised. This report documents the methods and results from updating of the habitat status of the biophysical mapping in the South Okanagan and upgrading the entire map product to current Terrestrial Ecosystem Mapping (TEM) standards (Resources Inventory Committee 1998). We have updated to the current Biogeoclimatic Ecosystem Classification (BEC) site series classification, which is soon to be revised. The new site series classification, including site series numbers and codes, has not been finalized. We have updated the biogeoclimatic zone and subzone boundaries, (BGxh, ESSFxc, IDFdk, dm and xh, MSdm andxk, and PPxh) ecosection boundaries (North Okanagan Basin NOB, Northern Okanagan Highland NOH, Okanagan Range OKR, and South Okanagan Basin SOB, and ecosystem units, including where recent burns and new developments have occurred. In 2006, unmapped gaps between the South Okanagan TEM and TFL15 TEM were mapped and added to the South Okanagan TEM. In 2006, the portion of the mapping in the Naramata OCP area was upgraded to delineate riparian and wetlands as distinct polygons wherever possible.
