Lupita Pena, center, receives some instructions from Kanin Routson, a graduate student at the University of Arizona, before heading up Tumamoc Hill for an early morning walk. Pena joined other walkers in the "citizen science" project aimed at gathering information on wildflower blooming patterns. The data gathered will help gauge the effects of climate change and other factors on vegetation.
Kanin Routson, a graduate student at the University of Arizona, counts the number of buds and blooms on a marked cholla bush on Tumamoc Hill. Routson is working with Gary Nabhan, a research scientist at the University of Arizona's Southwest Center, in gathering information on wildflower blooming patterns. The data gathered will help gauge the effects of climate change and other factors on vegetation.
