Euphorbia misera Outplantings

Cliff spurge (Euphorbia misera) is listed as a rare (list 4) species by the California Native Plant Society, and is only found growing naturally in one population on Santa Catalina Island. In order to increase this number, a new population was outplanted west of Little Harbor in November of 2000, with one quarter of the plants fenced to exclude non-native animals.

Management Objective:
To increase the number of viable Euphorbia misera populations on Santa Catalina Island from one current known population. Because reproduction in the existing population is currently thought to be low to nonexistent, determine if browsing pressures affect this plant and/or inhibit seedling survival.

Monitoring Methods:
Periodically assess the condition of all outplanted individuals in order to document the health and growth of these plants. Record such information as height, vigor, animal damage, pests and/or disease, and other threats.

Collection Frequency:
Twice per year during the months of March and November for the first two years, and annually in March thereafter.
