Arizona Ocelot

In February 2011 an ocelot was photographed in the Huachuca Mountains of southern Arizona. It was only the 3rd confirmed ocelot sighting in Arizona in the last 50 years. Over the last century, the U.S. population of the ocelot has been dramatically reduced. Restoring and protecting existing habitat is crucial because as an ocelot begins to mature it must leave its parents and go out in search of its own territory. More »

  • One of the Nation’s rarest plants, the sentry milk-vetch , Photo credit: Peter Rowlands, NPS

    One of the Nation’s rarest plants, the sentry milk-vetch (Astragalus cremnophylax var. cremnophylax), occurs only in Grand Canyon National Park, where it is known from three locations along the South Rim. This tiny member of the pea family favors a very specific type of habitat on the canyon edge within shallow depressions in the highly porous Kaibab Limestone. The plant is endangered due to its small population size, narrow range, and threats posed by recreational activity.

    The Apache trout (Oncorhynchus apache) is the state fish of Arizona, and is one of only two species of trout native to that state (the other being the Gila trout). This once abundant fish was decimated by over-harvest, habitat loss, and competition with previously reintroduced non-native trout species. Fortunately, the White Mountain Apache Tribe and other conservation partners have helped bring the species back from the brink of extinction.
