Hummingbird Monitors Needed
Arizona State Parks, Audubon Arizona, and the Hummingbird Monitoring Network are teaming up to study hummingbird diversity and migration patterns in Arizona. Data collected will help land managers protect natural habitats. Volunteer citizen scientists will be trained to observe hummingbirds and take field notes. The hummingbird project is funded by a grant from, an Audubon conservation initiative made possible by funding and assistance from Toyota. Other volunteer opportunities are also available.

Chinese Pistache
If you have sufficient space, consider deciduous Pistacia chinensis for your landscape. This tree's canopy offers dense shade and probably the most dramatic fall color available for the low desert. Foliage colors vary somewhat from gold to orange to scarlet, so buy it in fall so you can see what color you're getting if that matters to you. There are also named varieties available, such as Red Push. Chinese pistache drops all its leaves when temperatures cool, so you%ll have some raking to do, but deciduous trees make excellent choices to protect windows with eastern exposures. Determine your site size carefully because Chinese pistache grows about 40 feet tall and 35 feet wide, although can get up to 50 feet by 40 feet with perfect conditions.
