Grand Canyon National Park
In 2009, staff and volunteers removed 3,283,984 individual invasive plants from more than 1,340 infested acres. This amounted to the physical removal of more than 110 acres of invasive plant ground cover. This work was extremely beneficial for the protection and restoration of the park’s native ecosystems and the restoration of healthy and intact wildlife habitat. It amounted to more than 37,000 hours of labor removing invasive plants, restoring ecosystems, monitoring cultural and natural resources (including 805 hours in the Condor Nest Watch Program), and closing a dangerous abandoned mine.
Partnering with Bat Conservation International, staff and volunteers successfully installed bat-friendly closures to prevent human access to three mine openings at the Last Chance Mine site on Horseshoe Mesa below Grandview Point.
Installation of bat gates on Horseshoe Mesa in 2009. The NPS has undertaken several projects at abandoned mines throughout Grand Canyon to seal them for the safety of park visitors. Funds from the American Recovery and Reinvestment Act of 2009 (ARRA) are being used to secure numerous mine openings at the defunct mines. eams are installing bat gates and posting warning signs where appropriate.
