  • Chief of Engineers signs report recommending ecosystem restoration in Prado Basin

    The U.S. Army Corps of Engineers’ top general signed a report April 22 – on Earth Day – recommending a plan to restore more than 600 acres of valuable riparian habitat within the largest riparian forest in Southern California. Lt. Gen. Scott Spellmon, the Corps’ commanding general and 55th U.S. Army chief of engineers, signed the Chief of Engineer’s Report for the Prado Basin Ecosystem Restoration and Water Conservation Feasibility Study at the Corps’ headquarters in Washington, D.C. The project is headed by the Corps’ Los Angeles District, in partnership with the Orange County Water District.
  • USACE/NMSU Professionals Publish Joint Article

  • PUBLICATION NOTICE: Conspecific Attraction as a Management Tool for Endangered and At-Risk Species on Military Lands

    Abstract: Movements of wildlife species and associated colonization of habitats is often unpredictable, potentially leading to ineffective management and/or interference with military training. Habitat restoration for wildlife management on military lands is a common, yet expensive, response to federal conservation and mitigation mandates, yet viable wildlife populations often fail to become established on restored habitat. Conspecific attraction, using the tendency for individuals of the same species to settle near one another, can be a cost-effective means of attracting animals to newly created or restored habitats. This work demonstrated the use of conspecific attraction as an alternative tool for encouraging colonization of restored habitats by at-risk birds and amphibians. Conspecific attraction was relatively straightforward to employ, but its effectiveness varied among species. We demonstrated clear success in attracting some bird (northern bobwhite; Colinus virginianus) and frog (wood frogs; Lithobates sylvaticus) species into our target areas but other species showed a neutral response. Conspecific attraction presents a cost-effective alternative to current management practices such as translocation or colonization after habitat is created or restored. Only minimal equipment costs (<$300/broad-cast station) and nominal work-hours are required to set up the equipment, and total cost was ~$1,200 per demonstration plot annually.
