I think I sent you this, but just in case I didn't....They updated the species based on our comments. Attached is the
updated supplemental planting list for Dry Creek. I told them it was OK to proceed with ordering the plants.

Kim, this is actually the most up to date planting list for Dry Creek that we sent you. Jeff's last e-mail was the original
version that the IRT previously commented on. Our staff is preparing to order plants and wanted to make sure the IRT is
good with the updated planting list. Let us know if you have any questions or concerns. Thanks!

Kim, attached is the updated planting list for Dry Creek based on the IRT's comments. Below is a list of the changes we
made, and we will add random vegetation plots to the supplemental planted areas during MY4. Let me know if you
have any additional questions or comments. Thanks!

UT1 and Dry Creek

Box elder was reduced from 10% to 5%.

Red Mulberry was reduced from 10% to 5%.

Painted buckeye was added at 5%.

Minor adjustments were made to several species based on the reduction in mulberry and box elder.

UT6

Red mulberry was reduced from 8% to 5%.

Minor adjustments were made to several species based on the reduction in mulberry.

A riparian seed mix was added as well.

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.
