This past fall, ACE Pacific West South worked in Alpine, CA removing invasive plants and performing fuels reduction as a part of an ongoing 30-year restoration project managed by the Back Country Land Trust (BCLT). The ACE crew worked on removing four acres of the giant reed (Arundo donax). BCLT’s goal is to remove six acres of Arundo in riparian habitats over the next several years.
Arundo is native to eastern Asia, but can now be found globally. In the 1820s, it was introduced to Los Angeles as a roofing material and erosion control in drainage canals but has since escaped and become overgrown. It is one of the fastest growing terrestrial plants, growing as much as 10cm a day. Arundo is not only rapidly spreading but it is also highly flammable, making it a priority for removal as wildfires become more prevalent in the west. It also impacts freshwater sources and water tables, as it has been documented to use 300% more water than native plants in similar habitats.
Ultimately, this project will protect the San Diego watershed through invasive species removal, fuels reduction, and trash clean up. The work is ten years in, with five years to go and is then projected to be monitored for another twenty years. Secondary work completed by the crew included the removal of other known invasive plants, planting of native species in treated areas and the collection and removal of trash found at the worksites. ACE is proud to be a part of this important project with the BCLT!
