on the third Saturday of May. All the activities for EMTD are free and take place at the Visitor and Interpretive Center and at the Equestrian Staging Area. Natural history The park is in the California chaparral and woodlands ecoregion. It has coastal sage and chaparral and riparian habitats and plant communities of California native plants. 2003 Cedar Fire A significant portion of the park was burned by the Cedar Fire in 2003. As is typical of a chaparral ecology, within a few years the park had recovered and exhibited little evidence of recent fire damage.
