View across the Buenos Aires National Wildlife Refuge

The semi-desert grasslands at Buenos Aires National Wildlife Refuge support both native and nonnative grasses. In the last decades invasive, African origin, lovegrasses have proliferated. Looking west the high point in the background is Baboquivari Peak, an area sacred to the Tohono O’odham people whose nation is to the west of the ridge. The Mexico border is several miles to the south (to the left of the photo).
