Paddon/Gellhorn Wilderness Research Grants

Each year since 1998, the Indian Peaks Wilderness Alliance (IPWA) has awarded Paddon/Gellhorn Wilderness Research Grants.

These grants honor the memory of David Paddon and Joyce Gellhorn.​ David Paddon was an English exchange student in the Geography Department at the University of Colorado who did research in the Indian Peaks Wilderness. He died in a weather-related climbing accident in the Indian Peaks in May 1990.

 

Joyce Gellhorn was an IPWA volunteer, and a long-time board member the IPWA’s scholarship with the IPWA. Joyce was a dedicated educator whose passion was the ecology of the Colorado high country, which she shared in her books: Song of the Alpine: The Rocky Mountain Tundra through the Seasons, White-Tailed Ptarmigan: Ghosts of the Alpine Tundra and Aspen Dreams: A Memoir. She held a Ph.D. in botany with a specialty in plant ecology, and taught classes for over twenty-five years to students ranging in age from four to eighty-four at the Boulder County Nature Association, the University of Colorado’s Mountain Research Station, Boulder Valley Schools, Rocky Mountain Nature Association, Keystone Science School and Teton Science School.  Joyce passed away in 2012.

Eligibility

The Paddon/Gellhorn Wilderness Research Grants support graduate students pursuing Master’s or Ph.D. degrees at recognized Colorado-based institutions conducting research on Colorado's mountain ecoregions - alpine, subalpine, and montane - and their constituent ecosystems. Projects should aim to advance the understanding, conservation, or management of these systems by investigating biotic interactions (e.g., flora an fauna dynamics) and/or abiotic factors (e.g., climate, hydrology, geology) that influence these ecoregions and their ecosystems. 

 
Use of Funds


Funding covers research-specific costs, including materials, supplies, lab work and equipment. Travel and transportation related to the research are allowed but must not exceed 25% ($500) of the total grant. Funds cannot be used for personal living expenses (e.g., rent, groceries, utilities) or any non-research-related costs.

 

Application

In 2025, the IPWA is proud to offer four Paddon/Gellhorn Wilderness Grants, each up to $2,000. 

Applications must be submitted by Sunday, March 30, 2025, and award announcements will be made by Monday, April 15, 2025.

 

Interested applicants should review the 2025 IPWA Research Grant Announcement PDF for application instructions. 

Grant Award and Post-Award Requirements


Grants are awarded based on the research proposal's scientific quality and the faculty advisor’
recommendation. Recipients must submit a 3–5-minute, public-friendly video summarizing their findings by October of the funding year. Alternative formats can be arranged before grant disbursement to accommodate specific need.
