  1. Potential Revisions2007 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

  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
