Ecology Photo of the Month

The Morgan Fire of 2013 burned nearly 3,000 acres primarily on the east and south sides of Mount Diablo. In the spring of 2014 Nomad Ecology conducted a post-fire study of fire-following annual plants. In several of their plots fire poppy (Papaver californicum) was observed - an exciting find! Fire poppies haven’t been seen on Mount Diablo since after the 1977 fire, nearly 40 years ago.

    PROJECT: Vasco Road Safety Improvements Project
    LOCATION: East Contra Costa County
    CLIENT: Contra Costa County Public Works Department

    Conducted focused botanical surveys and delineated potentially jurisdictional wetlands and waters of the U.S. within the 5.3 mile long Vasco Road Safety Improvements Project area located near the boundary of Alameda and Contra Costa counties, California. Focused botanical surveys were conducted for federal and state-listed plants, CNPS plants, and plants covered by the East Contra Costa County HCP. The wetland delineation and focused botanical surveys complied with all requirements the East Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan (HCP/NCCP). Nomad met the expedited schedule associated with this Federal Recovery Act-funded project.
