Anderson Farm Stream Mitigation Bank
Adaptive Management Report — November 2019
I. Project Summary
The Anderson Farm Stream Mitigation Bank has remained stable, and the target plant
communities are developing across the site. The final (Year S) monitoring of the Bank was
conducted in September 2018. The project met the stated success criteria for stream flow and
vegetation density. However, the Interagency Review Team (IRT) required additional treatment
of the invasive vegetation as a condition of future credit releases and eventual bank closure.
At the request of the IRT, the Sponsor has conducted extensive treatment and physical removal
of invasive vegetation throughout 2019 (Appendix A) and plans to continue the efforts in 2020.
A brief discussion of the methodology can be found below.
II. 2019 Treatments
Chemical vs. Physical Control: Native Roots conducted chemical and physical control methods
in 2019. The physical control methods are two tiered. The first treatment was conducted to
manage pre -emergent growth with a chemical control. The second physical treatment was
conducted to facilitate access throughout the site. Paths were cut through impenetrable kudzu
to allow for foliar chemical treatments to be conducted. While cutting paths, Native Roots also
released some trees that had kudzu climbing on them.
Per Report from Native Roots:
Physical Control
• 3/20/19 - We mowed through kudzu for better access and released trees with climbing
kudzu vines.
Chemical Control
• 6/24/19 - We started the chemical control and realized that this was a much bigger
project than anticipated. We cut paths, released trees, and conducted foliar
treatments.
• 7/2/19 - We continued the chemical control. We cut paths, released trees, and
conducted foliar treatments.
• 7/18/19 and 7/19/19 - We continued the chemical control. We cut paths, released
trees, and conducted foliar treatments.

• 9/12/19 - We continued the chemical control. We cut paths, released trees, and
conducted foliar treatments. This was an extension of the original scope of work. We
continued further downstream and up slope than in the original plan.
Early October 2019 - We will walk the ground already covered and spot -treat missed
kudzu.
Chemicals Used - Within a SO -foot buffer of the stream we used 4% Garlon 3a with 1% Phase
surfactant. Outside of that buffer we used 6% Capstone with 1% Phase. These were all foliar
applications.
Impact on Existing Vegetation - On areas where the kudzu has completely covered all
vegetation, there will be some off -target damage to existing vegetation. However, in many
cases the kudzu had already impacted some of the vegetation. In many areas, other invasives
(multiflora rose and privet) were targeted with the same foliar treatment. Overall, this
treatment will benefit the target vegetative community by removing nuisance growth and
reducing competition for resources.
III. 2020 Plan
Treatment 1 (May) - Foliar treatment of kudzu and other invasives seen onsite. If there are any
invasive species deemed too large for foliar treatment, we will perform a cut stump treatment.
Treatment 2 (Late Summer) - Foliar treatment of kudzu and other invasives seen onsite.
Treatment 3 (Early Fall) - Spot -treat any species missed.
IV. 2021 and Beyond
While the 2019 and 2020 treatments will have helped the site significantly, the older root
crowns may need a couple of extra years of treatments to completely kill them. Also, there
may be dormant seeds that could germinate. Therefore, the site should be monitored, and
spot -treated as needed, for the next few years.
