What it could look like – a work in progress
Opening screen
Zone map
BEC map with options to link to
Zone
With a drop down menu to
access subzone variant
combinations
This will take you to the new
screen based on the variant
you choose.
Phase II version would be
done through the map
As you go further you get more detail
Subzone/Variant page
Background information is on the page along
with:
Links to other BEC guide information –
geographic location, climate, other background
info that is not used up front for this screen.
Link to landscape discussion if available
Link to forest health info relevant to this
unit.
Phase two could have photos,
Growth and yield information
Drop down of available Site Series – this links
you to the Site Series Screen
As you go further you get more detail
Site Series Screen
This screen has the following information.
List of ecologically suitable species – each hyper linked to a
compendium for that species.
Additional notes by species from Ecological field guides – e.g.,
on moister microsites
Information on forest health for this SS – anecdotal or published.
Link based on GPS and elevation to SPAR seedlot information.
As you go further you get more detail
Species specific Compendium
Information would include ecological
tolerances
Ecological amplitudes
Range in province
Growth rate and yield expectations

Tree Species Notes:
Pl is limited by shade intolerance and saturated soils; Sxw is limited by growing season frosts; preserve advance regeneration; Act, At, Ep – limited in
productivity, reliability and/or feasibility [Source: PR (LMHB 26); and the Reference Guide for FDP Stocking Standards Footnotes].

Site Limiting Factors
Management Implications
Management Options
Cold, wet, poorly aerated finetextured soils
Root restriction, reduced productivity, windthrow, soil
compaction
Mounding and/or elevated microsites for seedling establishment
Frost/cold air
Seedling damage / mortality
Mounding and/or elevated microsites for seedling establishment; partial canopy retention

SBSdk – Sub-Boreal Spruce Dry Cool Biogeoclimatic Subzone
Subzone Notes: Summers in the SBSdk are relatively warm and dry while the winters are typically cold and dry (snowpack < 50cm). The most
common tree species include Sxw, Pl, At, Act and Ep. Climax forests are dominated by Sxw however, due to the recurrent disturbances common to this
variant many forests are often dominated by Pl and At. Fd and Ep are relatively uncommon but where they do occur they are usually associated with drier
sites. Sb is typically restricted to wetlands and Act is most common along rivers and streams in association with Sxw.
Silvicultural Subzone Considerations:
Subzone Concerns
Identified Risks / Implications
Management Options
2nd growth shift in species composition
Resilience of ecosystems, forest health risks
Adopt appropriate mix of species
Understocking on Pl dry sites
Long term economics (I.e. forest health issues)
Increase Pl density
Climate change – inc. in growing season temp
Reduced Sxw productivity on drier sites
Shift proportions of species mix (introduce Fd)
Increase in MPB in the southern portions
Pl mortality
Overstocking on wet sites
