Ajo Peak To Tinajas Altas: Flora Of Southwestern Arizona: An Introduction

An introduction is provided for the modern and fossil vascular plant flora of the contiguous protected areas of Organ Pipe Cactus National Monument, Cabeza Prieta National Wildlife Refuge, and the Tinajas Altas Region in southwestern Arizona—the heart of the Sonoran Desert. These three entities encompass 514,242 hectares (1,270,700 acres), approximately 5141 km2 (1985 mi2). Elevation and ecological diversity generally decreases from east (Organ Pipe) to west (Tinajas Altas) while aridity increases from east to west, both correlating with decreasing botanical diversity.

Tim Lengerich, we miss you

Tim LengerichTim was a man who cared deeply for this region - the Sky Islands and especially the Sonoran Desert. He harassed the Forest Service consistently, worked hard to restore damaged landscapes, and wrote songs about all the beauty in the region. Hear some of his music here.

He spent countless hours camping and hiking wild places many of us never see. More than anything he hated seeing the places he loved destroyed, no matter by what hand. For this reason he really, really hated cows and ranching and tirelessly tried to stop it and teach people about its destructive impacts.

Tim had a heart attack and died on a summer day in 2010. He was hiking alone in Cabeza Prieta, pretty much his favorite spots on the planet. See his last set of photos from that day on Facebook.

We will always miss you, Tim. Hozho.
