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

Would it have been left anyway?

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

Invasive Plants How good is our data?

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

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.

# of trees = 0.1 ha patch DBHBA/treeInterior 30 m2/ha Coast 50 m2/ha

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
