Seed Planning Zones

Digital Map Files In 1998 Tree Improvement Branch (TIB) undertook a review of the interior Seed Planning Zones (SPZ) with the help of Research Branch. The final product of this review was digital map files for five species (interior lodgepole pine, interior spruce, interior Douglas-fir, western white pine and western larch). These maps were produced using an Albers Equal Area Projection. The map files that are located on TIB’s website are in various formats so they can be view using different platforms. The files are in ArcInfo, Arc Shape Arc Export and IGDS formats. These formats allow the user flexibility in viewing whether using ArcInfo itself, Microstation or GeoMedia. Plotter Files Along with the digital map files TIB had plotter files developed. These files can be printed on an HP650c plotter. For three of the species (interior lodgepole pine, interior spruce and interior Douglas-fir) there are several map sheets/plotter files for each species. These files are labeled in such a way that the first map in the series is for the northern part of the province, e.g. seed_fd1.hp2 and the highest number in the series is for the southeast corner of the province, e.g. seed_fd3.hp2. For more information refer to the table below. For the remaining two species, western white pine and western larch each has only one plotter file.

The review involved close examination of SPZ boundaries and the relationship between genetic class, seedling request ordering, transfer guideline application, and the biogeoclimatic ecosystem classification system (BEC). The review included input from Ministry and industry clients involved in tree breeding, orchard management, forest genetics, seed planning, and silvicultural activities.
