    Carlsbad Caverns

    National Park New Mexico

Chihuahuan Desert Lab

In November 2005, 10 volunteers ages 16 to 77—eight CDL students and two Chihuahuan Desert Alliance volunteers—worked alongside park staff to plant native trees at Rattlesnake Springs to restore habitat for the Bell’s vireo. They planted 27 netleaf hackberry, western soapberry and Goodding’s willow tree saplings. These saplings replaced Russian olive trees, which while providing the shrubby, dense habitat favored by the Bell’s vireo, are a non-native species and were removed by the park’s Exotic Plant Management Team.

The Chihuahuan Desert Lab (CDL) is one of five National Park Labs models designed to enhance science, math, and technology studies at the high school level. CDL is a comprehensive program that includes a resource-based curriculum and provides opportunities for students to participate in resource monitoring and stewardship activities at Carlsbad Caverns and Guadalupe Mountains National Parks. Focus topics include water quality monitoring of human impact, cave swallows, reintroduction and monitoring of prairie dog populations, revegetation of Chihuahuan Desert grassland ecosystem, and geographical information and global positioning systems (GIS and GPS)... special education modifications
