There's no perfect tree, this Tucson tree grower says. But we can start by planting native flora
KJZZ Phoenix
There are a number of efforts around the Valley to plant more trees — both as a way to help cool the air and to provide more shade. And Stephanie Vickers said certain types of trees are better for certain locations and to perform certain functions. But she says some growers also use the process of selection to try to almost create a better desert tree. Vickers is the sales and marketing manager at Civano Growers in Tucson. |

We Might Be Up a Tree
Arizona Highways
Cottonwood trees play a critical role in riparian ecosystems. But in the years since the first Europeans arrived, Arizona has lost 95 percent of its cottonwood habitat. Overgrazing, the damming of rivers and climate change have all played a role. It’s not looking good, but scientists are seeing signs of hope through naturally occurring hybrids. |

For Arizona tree care professionals, Boxelder Maple (acer negundo) presents both opportunity and management considerations in riparian and urban landscapes. Native to Arizona, this fast-growing, short-lived maple thrives along waterways, floodplains, and other disturbed sites with consistent moisture -- conditions common in parts of central and northern Arizona. Its opposite, pinnately compound leaves distinguish it from other maples, while its tendency toward multi-stemmed, brittle growth can create structural challenges and increased storm damage risk. As a dioecious species, seed production depends on the presence of female trees, and prolific samaras can contribute to volunteer seedlings in irrigated or unmanaged areas. While valuable for rapid canopy establishment, habitat support, and erosion control, box elder requires thoughtful pruning and monitoring for weak branch attachments. In the right setting, it remains a resilient native option for Arizona landscapes.
