A huge thank you to senior biologist David McMichael of the OC Water District. Before we set out David gave the group an overview of the basin, its function, biology and some of its conservation priorities.

Before we set out David gave the group an overview of the basin, its function, biology and some of its conservation priorities. The group understood the hard work and dedication of the biologists> We all learned about several interesting natural history topics at the basin, including the nesting pairs of endangered Least Bell's Vireos, the wild pigs within the bason, ellow-breated Chat's (that's a bird), various pond turtles, Willow Flycatchers, Chub (that's a fish) and much more. Controlling invasive, non-native plants is a huge battle in the basin. Some of these include Arundo, Kochia, Lepidium, Verbessina, Russian Thistle and others.

We then drove a walked a few miles of the basin, especially the areas near the extensive ponds and water treatment area.
