The netleaf hackberry (Celtis reticulata)—also known as western hackberry, Douglas hackberry, or palo blanco—is a hardy, drought-tolerant native that thrives in Arizona’s arid landscapes. Typically growing 20–30 feet tall, this small to medium deciduous tree is easily recognized by its gray, corky bark and rough, net-veined leaves with a deep green upper surface. Found throughout Arizona’s deserts, canyons, and sky islands, the netleaf hackberry provides critical habitat and food for wildlife: birds relish its sweet purple berries, while deer and other animals browse its twigs and foliage. Adapted to rocky soils and sandy washes with as little as seven inches of annual rainfall, this resilient species is a reliable choice for restoration and native landscape projects. |

Mesa Launches Tree Planting Season
Signals AZ
Mesa is partnering with community organizations and volunteers to plant hundreds of trees across the city as part of Trees Are Cool, a citywide initiative launched in 2023 with a bold goal of planting one million trees by 2050. By expanding Mesa’s urban tree canopy to 15 percent, the initiative will help create cooler neighborhoods, cleaner air, and more shaded public spaces. Achieving this vision will take a collective effort from the entire community. |

NAU’s tree inventory project brings intensive research to carbon sequestration on university campuses
Arizona Daily Sun
Northern Arizona University has been a notable educational leader in combining quality education with ambitious sustainability goals, and initiatives like the student-led Tree Inventory project and NAU’s Carbon Neutrality Plan assist in this. The tree inventory project started at the Office of Sustainability, where Erik Neilson, the university’s chief sustainability officer, wanted to find out more about various aspects of the trees on campus.
