Plants List
A plant group has been formed to help conduct a botanical survey of the park and to create an interpretive hiking trail for visitors. The interpretive hiking trail will be posted with signs identifying plants and presenting interesting facts about them, including their Native American names and uses. If you are interested in joining our plant group, please call Judy Zanolli at (760) 751-1870.
These are plants we project may be found in the Canyon. You can join our Plant Group to help us identify them!
