Bouverie Preserve stewardship staff recently partnered with a CAL FIRE crew from Glen Ellen to implement a series of planned 1 meter-square controlled burns in its grasslands and oak woodlands to determine the best control methods for rosy sandcrocus (Romulea rosea). The first set of spring burns was completed in June. Additional test burns will be conducted this fall.
Rosy sandcrocus is an invasive forb with great potential for severe degradation of California open spaces and rangelands. Almost no information is available regarding management of this species in California, though many landowners in the Sonoma County region report its recent colonization.
