The Lower North Thompson Community Forest Society’s main license area is shown below in red. It is east of Barriere along Barriere Lakes Rd.
Biogeoclimatic Ecosystem Classification (BEC)
The Community Forest is currently located in the Interior Cedar Hemlock (ICH) and the Interior Douglas-fir (IDF) BEC zones. The ICH is shaded in green, the IDF is yellow. The maps below were created using the web version of the ClimateBC model created by the Center for Forest Conservation Genetics (CFCG) based out of UBC. To learn more about the BEC system click here.
The main trees species in the ICH are western redcedar (Thuja plicata) and western hemlock (Tsuga heterophylla). Less abundant species found here are: Douglas-fir (Pseudotsuga menziesii), hybrid spruce (Picea engelmannii x glauca) and lodgepole pine (Pinus contorta). The zone is the most productive zone in the interior with very good species diversity. At higher elevations it transfers into the Engleman Spruce-Subalpine Fir (ESSF) zone (purple).
The main tree species in the IDF is Douglas-fir with various grass species in the understory. This is the second warmest forest zone in interior BC. At higher elevations it transfers into the ESSF and in wetter areas it transfers into the ICH. This is an important habitat for mule deer as their winter range is found within the IDF.
Climate Change and the Community Forest
Using the models provided in ClimateBC, a projection can be made for what the climate will be like in the future and therefore where the climate associated with each BEC zone will fall. The map below shows the projection for 2050 in the LNTCFS area. The prediction shows an increase in the area classified as IDF with the ICH moving up in elevation and decreasing in area. This is due to an overall increase in temperature and decrease in precipitation.
