Colin Leslie

Colin was born and grew up on a small farm in the country outside of Las Cruces, New Mexico. From New Mexico he headed off to college at Humboldt State University in the Northern California town of Arcata. Though the rainy Pacific northwest was a big change from the aired southwest, it proved to be one of the best choices of his life.
Colin received a Bachelor of Arts in Geography with an emphasis in GIS and Cartography. During his time at Humboldt, he was extremely fortunate to take part in a research project in Tibet where he spent two months and 2,100 miles documenting the impacts of transportation development in remote regions to subsistence Tibetan economies. During his time at Humboldt, he was also fortunate to begin his current career with the National Park Service where he spent each summer (with the exception of Tibet) working at Devils Postpile National Monument just outside of Mammoth Lakes, California. From Devils Postpile, Colin transitioned over to Yosemite National Park where he has spent the last three years working with the Branch of Visitor Use and Social Science. His work at Yosemite has included everything from wilderness management to transportation design and modeling.
He has continued developing his skills in the areas of GIS and statistics and looks forward to continuing his work and education with the Park Studies Unit at Colorado State University.

Crystal Brindle

Crystal is currently pursuing her undergraduate degree in Parks and Protected Area Management and will graduate in May 2014. Growing up in many of America’s national parks and working two summer seasons at the Backcountry Office in Rocky Mountain National Park has inspired Crystal to work toward an upper level management position with the National Park Service as a full time career. Until then, Crystal looks forward to learning more about the many components of management through her senior year courses at Colorado State University, a summer internship, and an upcoming social and ecological field methods course in Kenya. In her free time, Crystal enjoys landscape photography, running, and exploring wild places.

Ericka Pilcher
Ericka acquired her B.S. in Conservation Science from Muskingum College (Ohio) in 2003. After graduation, she drove west to Loa Utah (near Capitol Reef National Park) and worked as a therapeutic wilderness instructor for a year. In 2004, she returned to school to obtain a M.S. focusing on Parks and Protected Areas Management at Colorado State University with Dr. Peter Newman as her advisor. While focusing on human dimensions research and park management at CSU, she joined the NPS Natural Sounds Program at the NRPC in Fort Collins and cooperated on a variety of visitor use studies at Muir Woods National Monument, Grand Teton National Park, and Yosemite National Park. Soon after, she started work as a CESU contractor and was involved in a variety of projects related to soundscape planning, acoustics, visitor use, interpretation, and public outreach. In the spring of 2010, she received a biotech position at Bryce Canyon where she researched possible noise impacts to peregrine falcons. She joined the NPS (Denver Service Center) Visitor Use Management team in the fall of 2010, and has been working on planning projects related to visitor use in parks.
Ericka is originally from Ohio (Go Buckeyes), where most of her family still resides. Outside of work, she loves to oil paint, mountain bike, and trail run. Some of her favorite national park memories include listening to calving glaciers in Kenai Fjords, rafting down the Grand Canyon, summiting the Grand Teton, and camping in Kenya’s Tsavo National Park amongst the lions!

Lelaina Marin
Lelaina grew up in Southold, NY, a small town on Long Island. She attended Cornell University as an undergrad and received her B.S. in Natural Resources Management. After graduation, she began working for the US Fish and Wildlife Service in Hadley, MA as a Natural Resource Planner. With the USFWS, she helped develop Comprehensive Conservation Plans for various refuges throughout the Northeast Region.
In November 2007, she began working with the National Park Service's Natural Sounds Program. With this program she helps to preserve and protect natural sounds throughout national park units and minimize noise impacts to wildlife and visitors.
Lelaina has always been interested in wildlife conservation, but through her work with both the USFWS and NPS she became more interested in the human dimensions aspect of wildlife management. This is what led her to pursue a Master's in Human Dimensions of Natural Resources at CSU. Lelaina has recently conducted research at Sequoia and Kings Canyon National Parks in California, and is currently working as a Wildlife Biologist for the US Fish and Wildlife Service at Erie National Wildlife Refuge in Western PA.

Dave Stack

Dave is originally from Baltimore, Maryland, but has traveled around the country as part of his career with the National Park Service. His NPS career began, however, in his hometown at Fort McHenry National Monument and Historic Shrine where he worked as an interpretation ranger. After graduating with a B.A. in history from the University of Maryland, Dave continued his education at CSU.
Dave’s M.S. research tested the effectiveness of educational messages requesting quiet in Muir Woods National Monument. Based on this research, Muir Woods has permanently installed signs asking for quiet in the park.
Since completion of his M.S. in the spring of 2008, Dave has worked as a research partner for the NPS Natural Sounds Program, a ranger at the Statue of Liberty and a soundscape resources specialist at Bryce Canyon National Park.
Most recently, Dave completed the NPS Seasonal Law Enforcement Training Program at Northern Arizona University. Dave's interests include camping, kayaking, baseball (Go O’s!), music, and travel.
