Vegetation

Over 90 different plant species have been observed on site, including native plants, non-native ornamental and agricultural species and several different noxious weeds. Many of these species are pictured below. Recent weed management efforts include removal of Russian olive trees, eradication of myrtle spurge plants (a List A noxious weed and highest priority for removal) and removal of weeds along travel ways to help reduce additional spread.
