1 Potential Revisions 2007 checklist/protocol Stand-level Biodiversity

2 Constraints Why collect this data? –Modifies the total average retention

3 Would it have been left anyway?

4 Wetland RMZ RRZ Rock outcrop Non-commercial brush Non-merch Sensitive terrain

5 Invasive Plants How good is our data?

6 When is a stratum a clear-cut? If a stratum is CC: –No basal area equivalency –No windthrow, constraint or ecological anchor

7 When do a few trees change the type to DO from CC? Proposal: If dispersed trees >0.1 ha patch then must call stratum dispersed. OK to call stratum with <0.1 ha of retention dispersed.

8 # of trees = 0.1 ha patch DBHBA/treeInterior 30 m2/ha Coast 50 m2/ha 12.50.01245408 150.02170283 200.0395159 300.074271 400.132440

9 CC/DO Conclusion Don’t go to extremes to sample trees if likely <0.1ha equivalent If in doubt – go ahead and label as DO A CC label means you think any retention sums up to <0.1ha. Tree found in plots (e.g. 30 m radius) should always be tallied
