The High-Value Goals and Outcomes of Citizen-Scientist Projects

The Yosemite Lichen Inventory Project is an innovative park stewardship project using the productive collaboration between Rangers and Climbers in Yosemite National Park. It is made possible through funding provided by The Yosemite Fund and Centennial Challenge 2008, part of the Centennial Initiative of our National Park Service (NPS).

The inventory is part of the very important and comprehensive National All Taxa Biodiversity Inventory in the US. You can download a list of Centennial Challenge 2008 Park Projects.

Among other things, this project will increase the NPS' knowledge of species in Yosemite, helping them understand and effectively respond to impacts such air pollution and climate change on the park's natural resources.

The project also gives climbers, who have historically been leaders in mountain conservation around the world (such as American Alpine Club members Theodore Roosevelt and John Muir, shown at right), the chance to become very valuable long-term "citizen scientists" and "citizen naturalists" in the parks they enjoy and cherish.

'Citizen scientists' watch for signs of climate change

People with no formal training are helping scientists track and record birds, fish, stars, and plants in their neighborhoods online.


The 2007 Lichen Inventory Project

AAC members such as Ray Purcell gathered lichen samples to help scientists understand how the park might be impacted by global warming and climate changesThis project consisted of four days of lichen sampling in June on cliffs in Yosemite Valley and 4 days in August on the granite domes of Tuolumne Meadows area in the Yosemite high country.
