Background – what are we doing?
Ecological Anchors
Data Validation
Improvements for 2007
Fire Sites – what to do?
Stand Level Biodiversity Question
Is stand-level retention providing the range
of habitat with the structural attributes
understood as necessary for maintaining the
species dependent on wildlife trees and
CWD?
The underlying question is whether we are
maintaining the health or sustainability of
the resource.
Ecological Anchors
Ecological Anchors are structural elements that
will provide ecological integrity (structure and
composition) and resilience to the ecosystem.
Are Ecological Anchors PRESENT in Permanent
Retention strata?
Ecological Anchors
Big stick nests
Vet trees
Large Witches broom
Largest tree
Large hollow tree
Heavy CWD
Active wildlife trail
Cavity Nest
Active WT Feeding
Mineral Lick
Rare tree species
Are VET Trees Present?
ABSENT: Score of 0 (very high risk)
PRESENT: Score of 5 (low risk)
Risk Ranking & Ecological Anchors
Large Stick Nests
Goshawk nest
Bald Eagle Nest
Wildlife Trees
Culturally Modified Trees
Risk Ranking & Ecological Anchors
Are OTHER Anchors Present (Not vets)?
 For EACH retention stratum: Number of
Anchors OBSERVED per hectare
 SUM of all Anchors in Stratum(Form B)
Frequency of Ecological Anchors & Risk Scores
Absent = 0 (Very High)
<0.5/ha = 3 (High)
0.5 – 1.0/ha =7 (Mod Risk) >1/ha = 10 (Low risk)
DATA Validation
BEC classification: confirm validity
Strata Sizes (NAR, Gross): confirm in RESULTS
Species – confirm consistency and validity
Stratum – confirm type and consistency
Data – complete ? (Height, Diameter, Sp, Class)

FORM C – Block Information
 WTP Over-ride
 Invasive Plants: Keep to Listed Species
& Codes (Species and Distribution)
 Section 15: Time Resources
 Section 16: Do NOT duplicate stratum
Improvements for 2007
FORM B – Stratum Summary
 One summary for EACH Patch
 Protocol improvements to guide
summary
 Constraints and Ecological Anchors for
Patches AND Dispersed
Improvements for 2007
FORM A – Plot Information
 Full Count – put all info onto 1st Plot
 Plot ID: Numeric and NO repeats
 Data: Use APPROVED Codes &
Complete Info
Fire Sites – What to do?
 Wildland Fire following Harvest
 Wildland Fire pre-Harvest (Salvage)
