Audubon-Certified Home

After: Whitethorn acacia (Vachellia constricta), canyon hackberry (Celtis reticulata), creosote (Larrea tridentata), prickly pear (Opuntia engelmannii) and approximately 90 other local, native species make up this urban desert jungle. The dense plantings provide food and escape cover for wildlife (lizards and rabbits escape from neighborhood cats and approximately 45 species of native birds take cover from Cooper’s hawks, cats and other predators.

Wilder is proud to have its former headquarters recognized as the first Tucson Audubon Habitat at Home site. The landscape is constantly evolving to keep up with the maturing plants and knowledge we have gained. The story starts with what was once a manicured yard (the transformation had already begun in the ‘before’ photo shown) – an even, well-groomed layer of rock, a single south American mesquite, a border of purple-heart. Neat, orderly, and utterly sterile.

I grew up on the east side of Tucson, and played in a yard and neighborhood that took its birds for granted. Cactus wrens, thrashers, Cooper and Harris Hawks, coveys of quail, vermillion flycatchers, the constant murmur of doves. My new mid-town residence was sadly lacking all of these. The only constants were mockingbirds and the occasional verdin and, of course, English sparrows and pigeons.

Flash forward a decade or two. Gambel’s quail, brown-crested flycatchers, curve-billed thrashers, and cardinals are consistent sights. A phainopepla has shown up the last three springs to feast on wolfberries, graythorn berries and our immature, but growing mistletoe. This spring a pair of Abert’s towhees nested and successfully raised a baby in a wolfberry-ironwood thicket outside our bedroom window. There are warblers and vireos and birds we call skulkers that have so far evaded identification.

It’s our refuge and has become a haven for a variety of wildlife. One plant at a time, small additions have blossomed into a desert jungle.

Yellow-breasted chat in one of our desert hackberries. Desert hackberry (Celtis pallida) is one of our favorite wildlife shrubs. If you only plant one plant, plant this one. After maturing for a decade or so, our small forest of hackberries now regularly attracts the yellow-breasted chat on its fall and spring migration.

Shoot your quail block. After 10 years of composting or dumping the exotic vegetation in our yard (think lantana, aloe, oleander, privet, crepe myrtle and so on) and planting local, native plants the quail returned. Locally extirpated by cats and hawks because of a lack of native vegetation (quail depend on native thorn scrub to avoid predation), they somehow wandered into our yard and have been here ever since.

Lucy’s warbler in one of our catclaw acacias (Senegalia greggii). Another one of our favorite wildlife plants, the catclaw acacia deserves a spot in your yard. Numerous species of insect larvae feed on this typically small tree which, of course, attracts numerous species of insect eating birds. In addition to Lucy’s warbler, our catclaws are constantly patrolled by black-tailed gnatcatchers and verdins. Only local, native plants provide this insect feast which is the food chain anchor of our desert ecology.

First “cardinal” level Habitat at Home yard in Tucson.

Before: A concrete driveway, running the length of the front yard, was removed to create room for a path flanked by planting areas. The sunken planting areas receive roof runoff, and are lightly mulched to conserve soil moisture but not interfere with the constant foraging for food of wildlife.
