Wildlife-Friendly Fencing in the Mule Mountains
Part 2: Over the course of two weekends, SIA will be completing a new wildlife-friendly fence around Abbot Spring to help it recover from overuse by cattle. This is a great chance to see a new corner of the Sky Islands, meet people and camp, and either learn a new skill or share your expertise with others.
Celebrate the San Pedro
The Friends of the San Pedro River spring festival explores the cultural and natural history of the beloved Upper San Pedro River Valley. The event is free and will feature activities for adults and kids, a series of talks, and informational displays.
The event this year will emphasize history — you will be able to throw an atlatl, make an adobe brick, learn about the Clovis mammoth hunters and other native cultures, find out about the Amerind Foundation, and much more. SIA's Ranchos Regenerativos tech Karen Aglaee Lopez Roman will also be there tabling, so stop by and say hello.
