    Species Distribution

    For each tree species in BC we post a species distribution map overlain with Protected Areas. The distribution maps (see below) show a species range in terms of % cover. The cover values were obtained from the provincal ecology program's inventory plots. Cover values were compiled and mapped (using GIS) on the level of BEC subzone/variant. From these maps the total range and "relative" importance of a species by geographic area can be determined. [Printable, high resolution range maps are also available for download on the "Resources" section of this website.] Species range information is also given in terms of arial extent (ha) in two scale diagrams. The value marked with the black arrow in the "total range" scale diagram represents the total land area of the subzones/variants where the species might be found in some proportion. The value is generated by summing the land area for the subzones/variants where the species is know to occur (ie. species occured in an inventory plot(s) located somewhere in the subzone/variant). The potential range can be compared to that of other BC species by examing the relative position of the arrows. The red arrow indicates the smallest range of all BC tree species and the green arrow the largest. The portion (ha) of the species range which is protected (i.e. falls within a Protected Area(s)) is given in "protected portion" scale diagram. The coloured arrows (other than black) in the "total range" and "protected portion" scale diagrams do not necessarily represent the same species. For example, logdepole pine has the largest total range (ha) while subalpine fir has the largest protected portion (ha).


     

    Ecology, Reproduction, Genetics and other information

    For many of the minor or non-commercial species, we post information on general ecology, reproduction, genetic structure, resource management and seed transfer. The species summary information is largely founded on an ongoing GIS cataloguing project, the results from a workshop on minor tree species, and work undertaken previously by the Ministry of Forests (Yanchuk and Lester 1996). For commercial species, publications covering genetics and gene conservation issues are listed. We are in the process of updating the genetics information on these pages

     

    Conservation status summary

    We are currently in the process of producing in situ conservation status summaries for each species based on the published statistics from Hamann et. al. 2005 (download maps and conservation statistics). The Ministy of Forests is also in the process of summarizing the inter situ (experimental populations that comprise the breeding and testing program) and ex situ (primarily stored seed collections) conservation status for BC's trees. This information will be incorporated into the conservation status summaries when it becomes available.
