Hi Jeff,
I ran this by the IRT for comments and would offer the following:
1. Red mulberry and box elder are not high quality restoration species, but they are acceptable in low quantities in
the proposed diverse mix of species.
2. We appreciate the diversity of species proposed, including uncommon species such as Canadian serviceberry,
and multiple understory trees/shrubs.
3. Please add a native seed mix for any bare areas.
4. Please add transects to the supplemental planted areas and plan to monitor veg in MY4.
Thanks for reach out. Have a good weekend, Kim

Hi Kim,
Attached is the proposed supplemental planting list and map for Dry Creek. Wildlands' Scientist surveyed
supplemental vegetation plots throughout the potential low stem density areas on June 30th. Those findings are also
in the attached PDF. Even though several of the supplemental vegetation plots meet stem density requirements,
species diversity is below the required amounts. Due to the lack of species diversity, new species are being added to
the supplemental planting list. The total supplemental planting is 16% (2.3 acres) of the entire planted area (14.3
acres) at MY0, so an Adaptive Management Plan should not be not required.
Please let us know if there are any questions or concerns about the proposed supplemental planting plan. Thanks.
