Drought in Arizona: Observations, Impacts, and Projections

Presented by

Dr. Michael Crimmins

Tanque Verde Creek, Pima County, AZ in 2021.

Arizona has experienced dramatic hydroclimatic variability over the past several years with back-to-back record warm and dry summers and an intervening winter season with near average precipitation in 2020. The winter and spring seasons of 2021 are also shaping up to be drier and warmer than average helping to intensify short-term drought conditions across the state. At the same time, longer-term drought conditions dating back to the mid-90’s continue to impact water resources across the region.

Romero Pools, Pusch Ridge Wilderness, Coronado National Forest. February 2020.

What is the difference between short and long-term drought and its impact on different resources?  Is this type of shorter-term climate variability normal for Arizona or a harbinger of things to come? Will the current long-term drought end? This presentation will explore the unique aspects of Arizona’s hydroclimate that control precipitation variability at both short and long timescales as well as how increasing temperatures relate to drought conditions. We will also explore climate model projections for Arizona and what they mean in terms of potential changes in temperatures and precipitation patterns in coming decades.


Michael Crimmins, Profesesor of Environmental Science, U of Arizona.

Dr. Michael Crimmins is on the faculty of the Department of Environmental Science at the University of Arizona and is an Extension Specialist in Climate Science for Arizona Cooperative Extension. He has been in this role for 15 years working with ranchers, farmers and natural resource managers across Arizona to integrate climate information in their planning and decision making and assisting them in developing strategies to adapt to a changing climate. He also serves as a drought monitoring expert on the Arizona Governor’s Drought Task Force.

The zoom link for the meeting will be sent to the eblast mailing list on Monday, May 10, 2021.  The meeting will open at 6:45 pm to allow socializing before our speaker begins.

Floristic survey of Rio Vista Natural Resource Park in Tucson

Posted on Oct 04, 2020

John Scheuring and Gay Gilbert on a plant survey. Identifying plants without leaves, flowers or fruit is challenging!

In June 2020, the Tucson Chapter of AZNPS took on an important new project: to create a plant list for the Rio Vista Natural Resource Park in midtown Tucson.  The Rio Vista Conservation Project, in collaboration with the City of Tucson Department of Parks and Recreation, approached the Tucson Chapter to ask for help.  The Rio Vista Conservation Project attempts to identify and solve problems that might threaten the park’s integrity, and works to develop a long-term conservation plan that will guide the park in managing its resources effectively.   They wanted an up-to-date survey of the vegetation and plant species diversity in the Park to inform their ongoing conservation goals.

Despite the challenges of working on this project during the pandemic while maintaining social distancing and protecting public health, Tucson chapter members Suzie Husband and Melanie Campbell-Carter took the lead in organizing the plant census project and maintaining the collective records of plant surveys.  Eleven volunteers made 23 visits to the park in June and July, surveying and documenting the plants then present. Even in this drier-and-hotter-than-ever-before summer, 74 plant species were identified.  Click here for a link to the Rio Vista Natural Resource Park Dry Summer Plant List.

Because many plants in Arizona show strong seasonality, the group plans to continue the plant surveys throughout the seasons, with the next one scheduled for the end of September and into October, 2020.  They also welcome more volunteers who might want to participate in  this important project.  This is a wonderful opportunity for interested citizens to increase their knowledge and to hobnob with other plant experts.   If this piques your interest and you would like to volunteer or find out more, send an email to: plantsurvey2020@gmail.com. Melanie Campbell-Carter and Suzie Husband will be glad to respond to your questions.
