Importance / Issues
The development of the Klamath Network vital signs monitoring has emphasized the importance of documenting status and trends in the structure, function, and composition of ecosystems. Vegetation largely defines terrestrial ecosystem structure, function, and composition in the Klamath region; it dominates biomass and energy pathways; and it defines the habitat structure for many other life forms.
Vegetation ranked among the highest potential vital signs for monitoring in the Network's vital signs selection process. Vegetation is composed of primary producers upon which terrestrial and much aquatic biodiversity depend. Changes in vegetation structure, function, and composition will therefore have a profound effect on overall ecosystem structure, function, and composition and will be inextricably linked to the health of ecosystems. Therefore, monitoring vegetation change is imperative to detecting and understanding status and trends in park ecosystems.

Protocol Development & Status
Through a cooperative agreement, the Vegetation Protocol is being prepared by Dennis Odion of Southern Oregon University with assistance from Klamath Network staff.
Probabilistically sample vegetation and environmental parameters in safe, accessible locations every 3 years using a 3 year revisit frequency.
Sample special interest vegetation more intensively..
Monitor status and trends in vegetation composition at all sampling locations.
Monitor status and trends in vegetation structure and function, at all sampling locations, including parameters affecting (A) wildlife habitat, (B) fire behavior, and (C) stand dynamics.
Have the sensitivity to detect significant non-linear shifts in vegetation and a 50 percent gradual change in vegetation should they occur with approximately 80 percent power.
Provide data for modeling invasive species distributions as described in the Network’s invasive species protocol.
