She graduated with a BSBA from Columbia College in 1985 and has spent the last 37 years in the high-tech industry.

Jaime Roth
Board Member
Jaime Roth moved to Colorado “temporarily” in 2014 after living up and down the east coast. She fell in love with prairie dogs and mountain vistas first, but after settling in Longmont and beginning a rewilding project in her own backyard, a deep love of tenacious prairie ecosystems emerged. Jaime is a graduate of Tufts University and the University of Miami School of Law and has been an attorney for over two decades, primarily advising state and local governments. SPLT’s simple and effective approach of acquiring and preserving land for native plants and animals appeals to her passions and pragmatic sensibilities, all of which she is proud to bring to her role as Board Member.

Melinda Redenius

Aubyn Royall, who has recently rejoined the SPLT board, has worked in the animal welfare space for a decade. She graduated from University of Denver’s Sturm College of Law in 2014, and is the Colorado state director for the Humane Society of the United States. She has built her advocacy career in policy, from drafting legislation and lobbying, to stakeholder engagement and collaboration. Wildlife protection continues to be a core focus. Aubyn loves both the grasslands and the mountains, where she spends a few months each year.

Greg Litus
Board Member
Greg Litus helped get the land trust started in 1998 with the first acquisition of the Fresh Tracks Preserve. His career has spanned environmental consulting, farmed animal advocacy and agricultural research. Now retired, he contributes more time as a volunteer and looks forward to serving on the Board. Greg is convinced that wildlife protection through the preservation of threatened ecosystems and rewilding are essential for both mitigation and adaptation to the accelerating changes we humans are imposing on Earth.
