Perspectives on Researchneeds to link reforestationstandards to management
outcomesD. (Doug) A. Sklar
Executive Director
Forest Management Branch
FGYA AGM & Tech Session, March 6-7th, 20082
Why Link Standards
u Alberta ReforestationStandards Science Councilrecommendation 2000
u Recent OAG reforestationaudit noted same
u AB For. Mgmt PlanningStandard requiresdevelopment of linkedstandard
u “Alternative RegenerationStandards” (ARS) isfocused on getting us there
FGYA AGM & Tech Session, March 6-7th, 20083
Points of linkage1. MAI - ARS forecast culmination MAI
compared to TSA assumed culminationtarget
2. Forest structure – Planned future foresttypes compared to actual – area andstructure of strata
3. Voids – Area not reforested

Enabling Process :
u TM Regs changed
u Development ofcredible models
u Data sharing
FGYA AGM & Tech Session, March 6-7th, 20085
Limits to Endless Research
u Key factor is cost vsprecision trade-off
u Research must havepractical application
u Improve cost/precisiontrade-off, i.e. credibility
u KISS
FGYA AGM & Tech Session, March 6-7th, 20086
Research Needs: Broad
u Continuedimprovement ofmodels with newdata and/or newthinking
u Localization of‘developed’ models
u Focus on managedstands not ‘oldforests’
FGYA AGM & Tech Session, March 6-7th, 20087
Research Needs: Specific
u ‘Small’ tree dynamics
u Performance survey at14 – 20 years
u Forecast rotationsaround 60 – 120 years
u How much effort toexpend to capture smalltrees?
FGYA AGM & Tech Session, March 6-7th, 20088
Research Needs: Specifics
u Low density stands
u Models perform poorlyat low densities
u PSP data not from lowdensity stands
u Low density stand valuemay be in area otherthan fibre
FGYA AGM & Tech Session, March 6-7th, 20089
Research Needs: Specifics
u Enhanced forestmanagement practices
u Models not developed forthis application
u Few PSPs and fewmeasurements from EFMstands
u Will become important inthe near future
u Thinning and geneticstop priority
FGYA AGM & Tech Session, March 6-7th, 200810
Research Needs: Specifics
u Competition
u Models account for intertree competition only
u Small tree dynamicsimpacted by tree andnon-tree competition
u Competition is risk togrowth that we canmanage for
FGYA AGM & Tech Session, March 6-7th, 200811
Research Needs: Specifics
u Non clear-cut systems
u Strip harvest,shelterwood, patchharvests
u Range of tree sizes andspatial distributions
u Need data/modeldevelopment to accountfor these options
FGYA AGM & Tech Session, March 6-7th, 200812
Silviculture
u Accurate predictions of what standsresult from what treatments on whatsites
u Need cost effective andadministratively feasible system
