John & Gloria Tveten photographed and wrote about wildlife for over 35 years.

They were major winners in the 2000 Valley Land Fund Photo Contest.

They combined their photography and writing skills to produce the "Nature Trails" column in the Houston Chronicle for 24 years as well as hundreds of photo/text packages for major magazines. John passed away in 2009 but his images have been scanned and are still in circulation.

Daniel Mathews is a science writer focused on natural history of the Northwest.

He began with the much-loved book, Cascade-Olympic Natural History, later presented a different view of nature from the perspective of airline passengers, and recently made the most of the advantages of new media with a pair of iPhone apps covering more than 700 species of Northwest mountain wildflowers and trees.

He has taught natural history seminars through the North Cascades. He loves backpacking and shooting nature photos, from his home base in Portland, Oregon.

Larry got his first 35mm camera at 12-years old and has been taking bird and wildlife photographs ever since. He has contributed to the book titled “A Birder’s Guide To Florida” by Bill Pranty.

Larry wrote the chapter on Homestead and helped with the sections on Miami, the Florida Keys, and Everglades National Park.

Larry co-authored "A Birder's Guide To Metropolitan Areas of North America" by Paul Lehman and sold by the American Birding Association. He also contributed many photos in “Birding Florida” by Brian Rapoza as well as photographs for several birding magazines and Ken Kaufman’s “Birds of North America”.

Larry also leads bird tours around the U.S. and West Indies.

Rob Mies is an exciting and adventurous scientist, conservationist, TV personality, and animal expert whose passion is educating and entertaining people about the unique life on Earth and the simple ways people can conserve biodiversity. Rob has appeared on numerous TV shows promoting wildlife conservation including The Tonight Show, The Ellen DeGeneres Show, The Today Show, Conan O’Brien, Fox & Friends, CBS Early Show, and Martha Stewart.

Growing up in Michigan, Rob spent his school-age years traveling the Great Lakes exploring forests. He started researching wildlife at Eastern Michigan University studying endangered bats in the swamps of Michigan. Rob is the author of the books Bats A to Z and Understanding Bats, and the field guide Beginner’s Guide to Bats. He has 25 years of experience crawling through caves, wading through swamps, studying animals, and educating people around the world.

From wetlands to caves to rain forests, Rob’s research and conservation projects have taken him to all corners of the world. Rob’s conservation work has been featured in television documentaries by Paramount Pictures “Wild Things,” Germany’s “Nature Adventure,” National Geographic Television’s “America the Wild,” and Korean Broadcasting System’s “Return of the Documentary.” He was recently a featured scientist in the Discovery Channel's Trailblazers TV series (2016).

Nic and Randi Minetor are the photographer and researcher/author team behind 20 published guides on birding, hiking trails, historic cities, and America’s national parks.

Their titles include Backyard Birding: A Guide to Attracting and Identifying Birds (Lyons Press, 2011), and five books in the Best Easy Day Hikes series (FalconGuides, 2010 and 2011) on hiking trails in New York state, including Rochester, Buffalo, Syracuse, Albany, and the Hudson River Valley.

They have also published five books in the National Parks Pocket Guide series (FalconGuides, 2008 and 2009), on Great Smoky Mountains, Acadia, Everglades, and Zion and Bryce Canyon National Parks, and Gulf Islands National Seashore. Two more guides on Cape Cod and Assateague Island National Seashores will be released as e-books.

Residents of Rochester, NY, Nic and Randi have explored and photographed New York State's wildlife and natural resources for more than 30 years. 

Marc C. Minno has studied the ecology, systematics, and biogeography of butterflies and moths for much of his life.

He received a B.S. degree in entomology from Purdue University, a M.S. degree in entomology from the University of California at Davis, and a Ph.D. in zoology from the University of Florida.

He currently works as an ecologist for Eco-Cognizant, Inc., a home based consulting firm operated by spouse Maria Minno.

Since moving to Florida in 1982, Marc and Maria Minno have worked toward conserving the state’s rare, unique, and imperiled plants and animals.

Recently, he has been monitoring imperiled butterflies in the Florida Keys and southern areas of the state.

Marc frequently gives presentations and workshops on butterflies to local chapters of the Florida Native Plant Society, North American Butterfly Association, Audubon Society, and other conservation groups.

He is a past president of the Southern Lepidopterists’ Society and in 1999 received the John Abbott Award in recognition of outstanding achievement in expanding knowledge of Lepidoptera.

Marc is a research associate with the McGuire Center at the Florida Museum of Natural History in Gainesville, which contains the largest butterfly and moth research facility in the world.

Chad Moore holds degrees in Geography and Earth Science and has a longtime interest in the beauty and science of the night sky.

Chad co-founded the NPS Night Skies Team in 1999 and currently leads the program. His role as team leader has him advising parks on outdoor lighting, developing instrumentation to measure light pollution, and sharing his vision of starry nights with park rangers and the public.

Tyler Nordgren is a Professor of Physics and Astronomy at the University of Redlands. Prior to arriving at Redlands in 2001 he was an astronomer at both Lowell Observatory and the U.S. Naval Observatory in Flagstaff, Arizona.

He earned his PhD in astronomy from Cornell University in 1997 for work on dark matter in interacting spiral galaxies. In addition to publishing roughly two dozen peer reviewed scientific articles he is also the author of “Stars Above, Earth Below: A guide to astronomy in the national parks,” a popular science book dedicated to revealing what visitors to America’s national parks can observe in a dark night sky. Since 2007, Dr. Nordgren has worked closely with the U.S. National Park Service Night Sky Program to promote astronomy outreach and night-sky preservation in national parks.

Dr. Nordgren has helped document this vanishing landscape with award-winning artwork and night sky photography that has been on display in galleries from New York City to Flagstaff, Arizona and is on display in a number of national parks. As a result of this work he was a past-member of the Board of Directors for the International Dark-Sky Association. In 2012, NASA’s Curiosity rover joined Spirit and Opportunity on Mars carrying sundials, or “Marsdials” which Dr. Nordgren helped design with a team of seven other scientists and artists.

David G James developed a passion for butterflies at the age of 8 in the UK where he grew up. He received a B.S. degree in Zoology and Geography from the University of Salford and a PhD degree from Macquarie University in Sydney.

His doctoral thesis dealt with the overwintering biology of Monarch butterflies in New South Wales. During his career as an agricultural entomologist specializing in biological control he has published more than 170 scientific papers on arthropods ranging from spider mites to stink bugs to butterflies. He is an authority on acarology (mites and ticks), chemical ecology and integrated pest management as well as butterflies and moths. David is currently an Associate Professor in Entomology at Washington State University researching non-chemical and sustainable strategies for pest management in agriculture. He is also working on integrating sustainable, biologically-based pest management in viticulture with butterfly and pollinator conservation. As an authority on Pacific Northwest butterflies, David lectures publicly on butterfly biology and conservation and is actively involved in a number of citizen science projects that have butterflies as their focus.
