Seed Planning Units (SPU) & Species Plans
Seed Planning Units (SPUs) are the organizational units that form the basis for breeding and seed production planning. They are organized by species, seed planning zone, and elevation band.
For example #17, the Pli BV Low is the SPU for interior lodgepole pine in the Bulkley Valley seed planning zone at elevations below 1100 m. Based on the Forest Genetics Council Strategic Business Plan, SPUs are designed to facilitate program development and strategic planning for tree improvement.
A Species Plan
For each Seed Planning Unit (SPU), the potential economic return from a breeding and seed orchard program is determined. The SPUs are then ranked according to those indicating the highest return. Forest Genetics Council Species Committees develop species plans for those SPUs with the highest expected return.
Species plans contain
- Breeding and seed production projections,
- Plans for propagation and management activities, and
- Analyses of current and proposed seed orchards.
Species plans also show the timeline for genetic improvement, including projected supply and demand for planting stock, and projected genetic gain.
Each of the following files provides information on the timelines for a species/seed planning zone/elevation range combination
