Elizabeth Milford, Riparian Ecologist

Elizabeth Milford joined Natural Heritage New Mexico as a student employee in 1992, became an ecology research technician in 1997, and a research scientist in 2000.  She received her B.A. in Biology from Smith College in 1988, and her M.S. in Ecology from the University of New Mexico in 1996.  She has always had an interest in the natural world, fostered by her early adventures in the wilds of northern New Mexico and along the Rio Grande with her father.  She began work in riparian ecology while completing her Master’s thesis on ant communities in the Middle Rio Grande Bosque.  She continues to have an interest in entomology, but the focus of her work at NHNM has been riparian and wetland vegetation monitoring, assessment and mapping.  In her free time she enjoys hiking, rafting and camping with her family.

Corrie Reasner, Research Technician

Corrie started working for Natural Heritage New Mexico in August of 2014, shortly after she received her B.S. in Conservation Ecology from New Mexico State University.  She developed her love for the outdoors and conservation growing up in rural New Mexico and working with her dad on various habitat restoration projects on the middle Rio Grande. Much of her time at Heritage has been spent in the field across all of New Mexico collecting vegetation data for various mapping and monitoring projects. She spends what free time she has fishing, hiking, practicing her botany and hanging out with her dogs. She is also currently working on finishing up her M.S. in Biology with a focus on Plant Physiological Ecology at the University of New Mexico.

Amy Urbanovsky, Research Technician

Amy Urbanovsky received her B.S. in Biology from Oklahoma Christian University in 2011 and an M.S. in Environmental Science with a minor in Spatial Science from Stephen F. Austin State University in 2016. Throughout her time in graduate school, she worked as a GIS mapping analyst and research assistant on a variety of natural resource and wetland monitoring projects. Amy joined Natural Heritage New Mexico as an ecology research technician in 2017 where she has worked to develop the New Mexico Riparian Habitat Map and evaluate riverine wetland conditions throughout New Mexico using the Rapid Assessment Method.

Information Management/Geographic Information Systems

Richard Norwood, Information Coordinator/Data Manager

A recent transplant to New Mexico, Richard Norwood grew up in Central Arkansas where he spent a great deal of his time exploring the Ouachita and Ozark Mountains (especially the Buffalo National River). From these experiences, he developed a deep appreciation for the natural beauty and biodiversity of Arkansas. This fascination with the natural environment instilled in him a desire to protect these natural areas leading him to pursue a bachelor’s degree in Environmental Science from the University of Central Arkansas (B.S. 2014). After an internship with the Environmental Management division of Entergy Arkansas, Richard joined the Arkansas Department of Health’s Source Water Protection division as a GIS Analyst and left the agency as the GIS Supervisor in 2019. There he worked with multiple state, federal, and local agencies to enhance surface and ground water quality throughout the state. Richard joined Natural Heritage New Mexico as the Information Manager in the fall of 2019. He has since been working to build upon the New Mexico Conservation Information System to better serve the conservation science and natural resources needs of New Mexico.

Rayo McCollough, Emeritus Data Manager

Rayo McCollough was the Data Manager for Natural Heritage New Mexico (NHNM) from 2002 – 2019 and is now an advisor to NHNM. He has a B.S. in chemistry/archeology from Southern Methodist University and a M.S. in Environmental Science from the University of Texas at Dallas. He was a database consultant for 17 years before joining NHNM. He, along with NHNM staff and our many agency partners, created the New Mexico Conservation Information System (NM CIS), an online portal for biological conservation data, which includes the New Mexico Environmental Review Tool.  He works with government agencies, industry, researchers, and the public to develop innovative solutions for their information needs.

Colby Mohler, Assistant Data Manager

Colby Mohler has been with Natural Heritage New Mexico as the Assistant Data Manager since 2019. He received a dual B.S. from the University of Missouri in Forestry and Fisheries and Wildlife in 2017 and went on to obtain his M.S. in Forest Resources from the University of Arkansas at Monticello in 2019. At NHNM, he assists a diverse team creating and maintaining various databases and supervises our crew of data research assistants entering quality conservation data for New Mexico’s sensitive biota.

John Leonard, GIS Coordinator

Dr. Leonard has worked as GIS Coordinator and Spatial Modeler for Natural Heritage New Mexico since 2017. He graduated with a M.S. in Wildlife and Fisheries Sciences from Texas A&M University in 2008 and a Ph.D. in Wildlife Sciences from Texas A&M University – Kingsville in 2016. His Ph.D. dissertation involved conservation genetics and spatial ecology of the endangered ocelot in South Texas. From 2008 to 2010, Dr. Leonard served as a Peace Corps volunteer in Fiji. His major project during this time was to help the rural village of Namuaimada plan and implement a marine protected area on a badly degraded stretch of fringing reef. At Natural Heritage New Mexico, Dr. Leonard’s research centers around species distribution modeling, remote sensing, riparian mapping, and connectivity modeling.

Brian Dykstra

My interest in nature and wildlife in particular began while growing up on our family farm in Michigan. During walks through our fields and woods, I would often see white-tailed deer, ruffed grouse, songbirds, and other wildlife. After high school, I enrolled in Michigan Technological University’s Forestry Program and graduated with a bachelor’s degree in forest management. In the early `90s, after several seasonal jobs with the U.S. Forest Service, I returned to school to study wildlife management and ecology at South Dakota State University. My graduate work entailed studying songbird community dynamics in the Black Hills in South Dakota and Wyoming. In 1995, I moved to Arizona to work as a wildlife biologist. During 17 years working along the Mogollon Rim, I coordinated yearly Mexican Spotted Owl and Northern Goshawk surveys and conducted songbird, amphibian and bat surveys. I finished my Forest Service career in 2018 after 6 years as the Southwestern Region’s Wildlife Program Leader. In that position, I was fortunate to coordinate with a number of agencies and organizations, including Natural Heritage New Mexico. Working with NHNM on data sharing and management agreements piqued my interest in learning more about their data management systems and led me to eventually sign on as a volunteer. I have learned much about NatureServe’s rare species ranking system and am excited to now be working on NHNM’s Endemic Species Project.
