Welcome to Santa Cruz County CNPS
The California Native Plant Society (CNPS) is a statewide non-profit organization of amateurs
and professionals with a common interest in California's native plants. CNPS seek to increase
understanding and appreciation of California's native plants and to preserve them in their natural
habitat through scientific activities, education, and conservation.
The chapter meets every other month on the second Monday of the month at the
University of California Santa Cruz Arboretum Horticulture Building, located at 1156 High Street. Directions can be found
The chapter welcomes all-from the botanists and defenders of the environment to the casual nature lover.
Contact any Board Member to find out about the organization. Attend a meeting-you will learn something new!

Arana Gulch Coastal Prairie
Baseline Assessment Study: Summer 2013
A baseline assessment of vegetation conditions at Arana Gulch is one of the requirements of the Coastal Development Permit issued to the City of Santa Cruz by the California Coastal Commission. Section 3.7 of the Arana Gulch Habitat Management Plan (HMP) (Stanton 2013) describes the same purpose and justification of this summer baseline assessment of the Santa Cruz tarplant (SCT)/Coastal Prairie Management Area presented here including the details of field sample design and data analysis. The purpose of the baseline assessment is to characterize existing vegetation and ground cover conditions in areas that will be grazed under guidance of the Grazing Program specified in the HMP. Important monitoring variables include plant cover, canopy height, species richness, and ground cover. These data will enable a quantitative evaluation of changes in vegetation condition over time in response to grazing and will help the Arana Gulch Adaptive Management Working Group (AMWG) assess progress in meeting the specific goals and objectives of the HMP.
Goal 1: Maintain a viable Santa Cruz tarplant (SCT) population at Arana Gulch.
Goal 2: Reintroduce grazing to restore a disturbance regime that maintains functioning coastal prairie.
Goal 3: Minimize the detrimental effects of high non-native plant cover and restore coastal prairie species diversity and habitat function.
Goal 4: Maintain a genetically and demographically viable soil seed bank in perpetuity.
