- Siskiyou RCD works with partners through the KARISM (Klamath Alliance for Regional Invasive Species Management). The Klamath Region of California warrants its own invasive species management area due to considerations unique to the Klamath Mountains such as remote location, ecological diversity, rugged terrain, and tribal sovereignty. This group promotes a non-chemical approach to invasive species management in respect to Tribal ordinances against herbicide use.
- Siskiyou RCD partners with the Siskiyou County Agriculture Department in developing and implementing projects that control, reduce and eradicate invasive or noxious plant species within the District.
- Siskiyou RCD is a partnering organization of the Siskiyou County Weed Management Area.
