Example of how to use the Tree Species Selection Tool
Last updated on January 10, 2024This example for using the Tree Species Selection Tool provides a scenario, followed by a table with a series of questions that show how the tool can be used.
Example 1 – Western larch (Lw) in one of the sub-boreal spruce dry zones (SBSdk), in the Morice TSA. How to apply Lw expanded range map:
- Range and population expansion of western larch (Lw) for the Morice TSA, level of detail to BEC subzone variant
- Chief Forester’s amendment for expanded use of Lw (PDF, 369KB)
- Where to plant it? Access the expanded range maps
- Chief forester’s guidance for incorporating western larch into stocking standards (PDF, 187KB)

What has the natural and managed landscape supported in terms of tree species? |
Tree Species Selection Tool: SBSdk – tree species overview (PDF, 182KB) |
Composition and proportion of tree species in the mature and older stands, and principal species in managed stands. |
|
What are the basic silvics of Lw and suitable site series/edaphic conditions in the SBSdk? |
Tree Species Selection Tool: Silvical information, western larch (PDF, 419KB) Tree Species Selection Tool: BEC site series information SBSdk, description of sites |
Shade intolerant, infrequent on moist and very moist sites, tolerates acid substrates, frost intolerant. |
|
What are the ecologically suitable species in the SBSdk? |
Tree Species Selection Tool: SBSdk – ecologically suitable tree species list (SBSdk tab in the SBS ecologically suitable tree species workbook) |
Fd ecologically suitable but currently only in the eastern portion of the SBSdk. Ecologically suitable species review by regional specialists team developed the ecologically suitable species list without a management filter. |
|
Are there forest health risks to Lw in the area? |
Tree Species Selection Tool: Regional and District /TSA forest health strategies Also check with HQ and regional forest health specialists Forest health maps – shows short and long-term hazards. |
Check for other species choices, e.g., Pl, Sx, Fd in the SBSdk species lists and their forest health risks. |
|
Are there any operational or study data on Lw planting? |
|
|
Options – to mitigate risk and develop an understanding of suitable sites, plant mixtures of Lw with Pl and/or Sx, and not to exceed 50% stocking; and preferably clearly marked for tracking its progress.
