19th Research Insights in Semiarid Ecosystems (RISE) Symposium
October 21, 2023
The Program for the Symposium will feature invited speakers presenting recent or ongoing research on the WGEW, the SRER, or other outdoor laboratories in the region.
There will be time for questions from the audience, which will consist of federal agencies, NGOs (non-governmental organizations) stakeholders from southern Arizona, and university faculty, staff, and students.
Registration is required to attend because seating is limited to 80 people. Registration is free this year, and it includes lunch. Rather than charge for registration, we are asking for donations to cover the cost of lunch and the monetary awards to student poster contest winners.
Donations to Support the RISE Symposium Program and Student Awards
Please consider making a donation of any amount to support the Symposium Program and Student Poster contest awards (currently $1100 in awards). We no longer have a patron donating funds for the poster awards. You can donate at this URL https://give.uafoundation.org/SantaRita-RISE.

News
On Tuesday, March 21st, the University of Arizona and the Coronado National Forest Service signed a 60-year lease agreement on the 20-acre headquarters of the Santa Rita Experimental Range.
The story of the Santa Rita Experimental Range is inextricable from that of the Coronado National Forest, as well as the University of Arizona and its land-grant mission: university researchers have studied the ecology and management of semiarid grasslands on the now 53,000-acre site since its creation by President Theodore Roosevelt in 1902. The new lease agreement for the headquarters of the range expands the term to 60 years from the previous term of 20 years.

On February 6th, 2023, "in recognition of their continued collaboration with the University of Arizona implementing adaptive management of rangelands on the Santa Rita Experimental Range and for their contributions to the science of range management", Andrew and Micaela McGibbon (Santa Rita Ranch) were awarded the "2022 Range Manager of the Year" by the Arizona Section of the Society for Range Management during the annual conference at the Maricopa Agricultural Center.
See Past Events for more information.

February 2023 marks the tenth anniversary of the Dryland-Detrital Input and Removal Treatments (D-DIRT) experiment at the SRER. The DIRT network (https://dirtnet.wordpress.com/ ) explores how changing inputs of plant litter affects the storage and stability of carbon in soils. This network has ~10 long-term sites in mesic forests throughout the world. Arizona State University professor Heather Throop established SRER as the first Dryland-DIRT site to explore how soil organic matter processes are affected by litter inputs and drylands. Throop and collaborators maintain plots annually, but soil organic matter formation and stabilization is a long-term process and they anticipate tracking changes over decades. They collected their first comprehensive soil sampling in February 2023 and are looking forward to sharing results at a future RISE Symposium!

2023 RISE Symposium
The 19th annual Research Insights in Semiarid Ecosystems (RISE) Symposium will be held on Saturday, 21 October 2023, on the University of Arizona campus.
Visit the RISE website to see program and deadlines, register for the conference, and learn more about the symposium and the poster presentations.
Long-term Vegetation Transects
The Long term Vegetation Transects database provides access to long-term (from 10 to more than 70 years) records of vegetation measurements completed at 1 to 7-year intervals on over 200 permanent transects on the SRER.
Repeat Photography
The Repeat Photography database provides access to the archive of photographs taken repeatedly over the years from the same 115 sites across the SRER. The earliest images were taken in 1902.
Grazing Management Plan
The current Livestock Grazing Management Plan on the Santa Rita Experimental Range from 01 November 2022 to 31 October 2023 is online!
All the previous grazing plans as well as all the information about the Livestock Grazing History on the SRER are available at Livestock Use.
Water and Carbon Exchange
Access the USDA-ARS Ecosystem-Atmosphere Water and Carbon Exchange database and graphs to know more about the exchanges of water vapor and carbon dioxide between the land and the atmosphere on the SRER.

Centennial Conference 2003
The Proceedings from the Centennial Conference 2003 provide a complete overview of more than one century of publications about the SRER.
"The vast opportunities for future research at the Santa Rita Experimental Range
are built on the rich legacy of a century of observation and research.
In addition to opportunities, there are obligations to maintain and add to this legacy.
Therefore, our future efforts should ensure a second century of research on the Santa Rita"
