150+ Volunteers Armed with GPS to Map Flow of San Pedro River
Hear first-hand volunteer experiences; talk to water expert about future
June 04, 2013
Who: 150+ volunteers will be on foot, armed with GPS technology, measuring where water is present on the San Pedro River. Volunteers say the rewards of having great wildlife encounters, rare access to scenic river stretches, and knowing they are having a positive impact outweigh extreme heat, quicksand and other challenges.
What: 15th annual San Pedro River mapping to determine where water is present. Dozens of partners coordinate this massive effort that covers over 270 miles within the San Pedro River Basin. In addition to local residents along the river, the partners include the Bureau of Land Management, Community Watershed Alliance of Benson, Cascabel voluneers, and Mexican partners and landowners.
When: Saturday, June 15 at 6:00 a.m. – 12:00 p.m.
Where: The San Pedro River, from its headwater streams in Mexico to its confluence with the Gila River near Winkelman, tributaries of the San Pedro including the Babocomari River, Aravaipa Creek, Hot Springs Canyon and many other smaller tributaries, covering over 270 river miles. When this effort began in 1999, volunteers mapped 50 river miles. BLM National Conservation Lands include the San Pedro Riparian National Conservation Area and Aravaipa Canyon Wilderness.
Why: The increasing demands for water coupled with drought conditions continue to affect water availability in the San Pedro River Basin for both people and nature. Because the extended drought continues, this project is increasingly urgent to determine long-term trends. Last year’s mapping revealed that water was present in 29 percent of the river overall in late June before the monsoon rains began. By determining what areas no longer flow via the annual mapping, the Conservancy and many partners can determine where to focus conservation projects. The health of the San Pedro is important to our future, and the millions of birds that use this migratory pathway each year.
Impact: As we move into our 15th year of mapping, our science shows us that our conservation actions are having a positive impact. But, there is much more work to do! Some of the big conservation projects underway involve partnering with private landowners, ranchers, local state and federal agencies in both the U.S. and Mexico. Over time, these efforts will help to ensure that the river continues to flow, supporting local communities, agriculture and wildlife.
