The San Pedro Wet/dry Mapping Project Storymap

Description

San Pedro River Wet/Dry Mapping is a citizen science initiative launched in 1999 by The Nature Conservancy (TNC) to monitor the health of the river system. Every third Saturday in June, volunteers, staff, scientists, and land managers walk the river and its key tributaries to record the presence or absence of surface water, creating an annual snapshot of the waterway's condition at the end of the dry season. This data helps researchers understand long-term trends in surface water and the shallow groundwater that supports it, which thereby helps to identify areas for conservation efforts like water recharge projects, conservation easements, and habitat improvements for fish and wildlife populations. 

As you scroll this storymap, you will see examples of the partnerships, research, restoration, and water management decisions the project data has supported over the years. Additionally, explore key ecological observations made during mapping and lessons learned from our analysis of trends.
