OREGON STATE UNIVERSITY

About

Researching the connections between ecohydrological processes and human interactions in an ever-changing climate.

  • We investigate land use effects on ecological and hydrological processes and interactions.

  • We study surface water and groundwater relationships in watersheds and riparian areas. 

  • We use a systems approach to enhance base knowledge regarding watershed-riparian function.

  • We collaborate with multiple stakeholders, including producers, state and federal agency personnel, and researchers from various institutions.

The 2025 Society for Range Management (SRM) Meeting & Conference brought together land managers, scientists, educators, students, ranchers, and conservationists to discuss the current and future state of rangeland ecosystems. Ecohydrology lab members Aarón Ortega-Gonzalez, Daniel Gomez, María Iglesias-Thome, and Ross Shipley attended this year's meeting along with Dr. Ochoa to present their research projects in both the oral and poster presentation sessions. Seminar Sessions: • María Iglesias-Thome: Measuring atmospheric carbon fluxes in dryland pastures in Oregon, US • Daniel Gomez: Evaluating carbon, nitrogen, and organic matter content in irrigated and non-irrigated pasturelands in Oregon, USA. • Aarón Ortega-Gonzalez: A comparison of post fire aerial seeding and natural regeneration on Great Basin rangelands Posters: • María Iglesias-Thome and Daniel Gomez: Linking Atmospheric Carbon Fluxes, and Belowground and Aboveground Carbon Stocks in Rangeland and Pasture Ecosystems • Ross Shipley: Assessing Ecohydrology Response to Juniper Removal at the Watershed Scale
Dr. Ochoa was a plenary session speaker invited to present on his ongoing research and technology used to investigate surface water and groundwater relationships on rangeland and agricultural systems of Oregon and other parts of the West. The event organized by the Mexican Society for Rangeland Management, University of Chihuahua, and the Agriculture Reseach Institute INIFAP was held on October 17-18, 2019 in Chihuahua, Mexico.
Dr. Carlos Ochoa from OSU was the invited speaker to deliver a lecture on integrated watershed-riparian systems management to faculty and students of the Universidad Autonoma de Chihuahua (UACH) in Mexico. Dr. Ochoa discussed his research findings regarding surface water and groundwater relationships occurring on rangeland ecosystems of central Oregon. The event took place on 21 March 2019 at UACH’s Facultad de Zootecnia y Ecologia (Department of Animal Science and Ecology) auditorium in Chihuahua City, Mexico.
During the last two weeks of November 2018, Nicole Durfee, a Ph.D. student in our Ecohydrology team, will be leading a series of presentations based on her doctoral work on Unmanned Aerial Vehicles (UAVs) at OSU. During her various presentations, she will speak to various groups in the Falkland Islands, in South America, on the use of UAVs on agricultural, rangeland, and forestry applications. Several workshops will be held over this time to provide participants with “hands-on” experience with UAV operation, mapping, and basic image processing. Nicole's participation in this event is possible through a partnership with the South Atlantic Environmental Research Institute’s Coastal Habitat Mapping project, through the Shackleton Scholarship Fund.
