Bi-National Conference September 19-23, 1994 Tucson, Arizona
This conference brought together scientists and managers from government, universities, and private organizations to examine the biological diversity and management challenges of the unique "sky island" ecosystems of the mountains of the southwestern United States and northwestern Mexico. Session topics included: floristic resources, plant ecology, vertebrates, invertebrates, hydrology and riparian systems, aquatic resources…
People know about mistletoe berries, but Condalia globosa appear to also be a favorite food source for the Phainopepla.
In the Shadow of the Wall, a two-part Defenders of Wildlife report, explores these and other conservation consequences of extending the wall along the U.S.-Mexico border in detail.

The Apachian-Madrean region is a zone of confluence and geographic termini of species and floras from the north and the south. Lower and intermediate elevations support many taxa of tropical plants and animals that are at their northernmost limits. It is a region of tremendous habitat diversity and species richness. Much of the region remains little known, and quantified data are scarce. This report offers brief synopses on the insect fauna, ichthyofauna, herpetofauna, avifauna, mammals, and…

This was a long trip over a short distance. A large cadre of biologists from Arizona and Sonora made the trip to enhance biological data about the mountain and region.
The trip was initiated near Nacozari de Garcia with the destination being the high point of the Sierra el Tigre just above the small community of El Tigre.
We traveled through the La Caridad Mine and across Rio Bavispe at La Angostura Reservoir, then north near the eastern edge of the reservoir, before heading…
The Sierra la Mariquita was decreed a Voluntary Protected Natural Area on May 12, 2015. This Sky Island is owned by the Instituto Nacional de Astrofiscica (the Mexican national astronomy organization).
The Sierra San Francisco is a low-desert mountain range at the edge of the Gran Desierto of northwest Sonora. This range is owned by an ejido and protected as desert bighorn sheep habitat.
Early 2015 was quite lush due to good winter rains and previous-year hurricane remnant moisture.
