Thanks Kim. We will add some transects in the pond areas that are replanted. Have a good weekend!

Good morning Jason,
Thanks for the feedback. We don't have any further questions. We're fine with your approach to replant the pond
beds as long as additional veg transects are added to monitor success.
Have a good weekend,
Kim

Kim, we share your concern over the murdannia this early in the project, however, we are prepared to deal with it.
We have people who are experienced in treating it and will be working on controlling it at the site. The areas of
murdannia will be carefully treated to reduce non -target damage as much as possible. We will work to establish
temporary seed after the last treatment of the season in August, and once the murdannia is effectively under control,
a native seed mix will be seeded in the treated areas. We will re-evaluate and replant woody species as necessary.
As stated in the mitigation plan, the pond sediments were removed along the stream corridor through each pond and
replaced with fill material from the removed dams. The new stream channels were constructed through the fill
material. Beyond the stream corridor, the pond bed sediments were not removed. The old pond bed along Big
Bugaboo Creek does not have cracking, but portions of the old pond bed along UT3 do. We have seen this on other
successful projects such as Bethel Branch and Catfish Pond. Once the old pond beds dry out during MYl,
vegetation seems to grow well. There is no plan to remove the old pond sediment since we feel that these areas have
drained enough for vegetation to adequately grow.
Let me know if you have any other questions or concerns before we move forward with these actions. Thanks!

Hi Jason,
Erin, Travis, Andrea, Casey and I discussed this and since this is only the first year for this project, the IRT is OK
with the proposed treatment of the murdannia. If this was later in monitoring, we'd likely require an adaptive
management plan. It is concerning that it is already covering a large portion of the site. From my understanding,
glyphosate is somewhat effective; however, it will likely eliminate the herbaceous layer as well. We anticipate that
several years of treatment will be required until the present seed source has germinated and been treated. Once the
murdannia has been eliminated from the site, we will require a native herbaceous seed mix to be planted. Hopefully
you will be able to treat it in the wetland areas that are adjacent to the conservation easement as well.
Regarding the pond beds, was the site constructed during a wet time of year that prevented you from removing the
sediment from the pond bottom prior to planting? Is the sediment dried and cracking? Does the replanting include
removing the old sediment and applying soil amendments, or do you feel that the areas have drained enough that a

second planting would be successful? We've observed many restoration projects through old pond beds where the
sediment was not removed and it results in a fractured surface with a herbaceous layer and very limited stem
survival. We would suggest that you look at the wetland indicator status for the proposed species and only plant
those that are FACW and OBL; for example, Northern Red Oak is FACU. Lastly, we'll require additional veg
transects in the replanted areas to monitor success.
Please follow up with more details for the pond bed replanting. Reach out with any questions.
Thanks
Kim

Kim and Erin, I wanted to give you a quick update on Bug Headwaters and make sure you are fine with our
proposed management of the project this year. The first issue is that murdannia is growing in the wetlands and
streams throughout the project. Attached are the CCPV Maps showing the locations of the murdannia and the
Vegetation Condition Assessment Table from the MYl Monitoring Report. The plan is to spray the murdannia site -
wide in May and assess the site a month later to determine what further actions will be necessary. A follow up
treatment will most likely be necessary, but until we see how the murdannia responds to the original treatment, we
won't know what our plan of action will be.
The second issue is that portions of the old pond beds are very saturated and a majority of the planted trees have not
survived. This encompasses an area of 1.75 acres, approximately 9% of the planted area of the site. Attached is a
proposed planting list with the species, type of plant, quantities, and a note to which plants were in the approved
Mitigation Plan. The plan is to plant these areas in late February 2022.
If you could review the attached information and let us know if you have any concerns with our management plan
moving forward, it would be greatly appreciated. Let me know if you have any questions about it. Thanks!
