The Research Associate Program at GBI, in cooperation with NPS at Yosemite National Park is recruiting four (4) Invasive Plant Management Technicians to support vegetation management throughout the park. In addition to using mechanical and chemical methods for invasive plant treatment, responsibilities of these positions also include volunteer management, seed collection and processing, and rare plant survey and protection. The work is a mix of front-country and off-trail work in a wildland setting and may include travel outside the park to neighboring public lands and other National Parks. The primary projects these positions will support include: Yosemite Valley restoration projects, Washburn Fire and Mariposa Grove of Giant Sequoias post-fire rehabilitation.
This work will take technicians to many places throughout this spectacular National Park. The foothills are lovely in the spring with amazing flower displays carpeting the hills. Higher in elevation, work will be conducted in montane meadows including in Yosemite Valley under Half Dome and El Capitan. Project work will also take place in old growth giant sequoia groves, montane forests, and subalpine ecosystems under snow-covered peaks in Tuolumne Meadows.

Location:
Yosemite National Park is world renowned for its giant granite walls, waterfalls, sequoias, beautiful meadows, and snowcapped mountains. The Park encompasses nearly 750,000 acres of the central Sierra Nevada Mountains in California and is 94% designated wilderness. The elevation ranges from just under 2,000’ to just over 13,000’, and many ecosystems can be found within, including foothill chaparral, oak woodland, mixed conifer forest, subalpine meadows, and alpine fell fields. The Park hosts over 1,500 plant taxa and many animals, including special status, threatened, and endangered species. Yosemite is one of the most sought after climbing and hiking destinations in the world. Many additional recreational opportunities abound including botanizing, birding, fishing, swimming, and skiing.
