Martin Hagne

Executive Director

Martin Hagne was born and raised on the Swedish west coast, where his grandfather instilled a love for nature at an early age. He moved to the United States, and the Rio Grande Valley of Texas, in 1979 and turned his focus towards wildlife viewing and conservation concerns.
Martin served as the Executive Director of the Valley Nature Center in Weslaco, Texas, and environmental education facility, for 13 years. He then moved to Bandera, Texas where he led the Flying L Resort and Conference Center. He has also worked as a Field Biologist doing baseline studies for many years, including avian, herp, mammal, T&E, and habitat studies.
He enjoys leading birding field trips in the US and Mexico and has served on several state, regional and local environmental appointments, committees, and boards. Birding, nature viewing, native plants, conservation issues and environmental education are his great passions.

She received a Master’s in Biology from George Mason University for her work on wintering waterfowl on the Northern Virginia Piedmont and a Ph.D. from the same institution in the spring of 2008. Her dissertation involved the effects of pesticides on birds that nest in agriculture in the north central states. She is thrilled to be back in her home state of Texas.
