NLI Board of Trustees and Affiliations

“Perhaps nobody before us had seen the need or been able to set aside natural areas. And those that follow will no longer have the chance. They will only be able to care for what we leave them.”  ~ George B. Fell

Rick Barton
Retail Operations Manager, Rocktown Adventures

Rick's Bio
Rick describes himself as an “addict”, referring to his passion about the outdoors and nature. He grew up in Peoria and Macomb where he played in nature as a child. In 1967 his family moved to Rockford and while he was doing an Eagle Scout project at Hononegah Forest Preserve he became aware of invasive species. Since 1973 he has been selling people on outdoor recreation for various recreational businesses. He has had many explorations in nature and has always been interested in nature and education. He took a U of I Master Naturalist class in 2010 where he met Trip Thienemann and Judy Barnard, who were both on the board at that time. Judy invited him to be on the board and has since become involved at many levels. He currently serves as chair of the Board Development Committee and  is a member of the Education Committee.


Ellwyn Englof
Engineer, Ingenium Technologies

Ellwyn's Bio

Ellwyn was introduced to NLI around 2010 by Judy Barnard through serendipitous circumstances. He doesn’t have much nature background, but did grow up playing in nature. When he went to college he considered studying something related to nature, but instead got an engineering degree, based on his father’s recommendation to get a degree he knew would allow him to earn money. Nature became a hobby and is now taking more of a front and center position.  He has enjoyed his time on the NLI board and thinks it’s a great organization.  It’s a good idea to be on many committees, especially land conservation, to gain an understanding of what NLI does.  A presentation at his Rotary Club about the Kishwaukee River Ecosystem Partnership’s Green Infrastructure Plan about runoff impact really impressed upon him the critical nature of the need for protecting natural resources.


Ruth Little
Executive Director, Girl Scouts of Northern Illinois (retired)

Ruth's Bio
Ruth’s father was born in a sod hut in the prairies of Saskatchawan (Canada) and grew up on a Menonite preserve. She spent her youth in the prairies on the east coast of the U.S. What she learned about prairies made her feel more connected to her dad. After moving to Rockford she met Jerry Paulson (former NLI Executive Director) on a Christmas Bird Count and eventually became involved with bird banding and Natural Land Institute. Ruth loves to continue learning. She learns something new every day. Ruth was the Executive Director of the Girl Scouts of Northern Illinois for several years.


Tom Ptacin
Financial Advisor, Savant Capital

Tom's Bio
Tom has been attracted to natural areas all his life. He grew up in Beloit near Turtle Creek and loved exploring outdoor areas around the creek.  Tom likes to support the underdog and thinks animals and plants need someone to root for them so he thinks being involved with Natural Land Institute is a great way to do this.


Paul Baits
Electrical Engineer Manager, Sundstrand /UTAS (retired)

Paul's Bio
Paul is a lifelong resident of Rockford. Although the home he has always lived in is inside Rockford’s city limits, it is located on a four acre lot that includes a two acre prairie. Quietly sitting in that prairie, gazing at the birds and sky, and just thinking was a summer joy. As a youth, Paul’s family was friends with Owen Gromme (renowned wildlife painter from Baraboo, WI). Mr. Gromme and his daughter helped the entire family learn to rehabilitate orphaned and injured birds. Family vacations were, typically, road trips to national parks. Paul’s parents and siblings are long-time supporters of many environmental organizations, particularly the Nature Conservancy, which later motivated family members to become committed supporters of the Natural Land Institute. When retirement from the engineering career and the end of another significant volunteer commitment ended, the transition to NLI was a natural fit. He is on NLI’s Land Conservation, Finance, and Science committees. Paul knows that it is imperative that we protect unblemished natural areas and the creatures that depend on those areas for their survival.

Jon was the original staff biologist at Waubonsee Community College and set up the biology program there where he taught for five years. After this he bought a greenhouse and garden center in Oswego and ran it for 16 years. Jon was hired as a landscape designer and planner for Kane County Forest Preserve District and eventually became the Director. He retired from there 2004.

Rolf (Trip) A. Thienemann, III
Attorney at Law, Rolf A. Thienemann, III

Trip's Bio

Trip became aware of NLI when he had a furniture making business many years ago.  He thought about marketing it to the RSO audience through the program book. The spot he wanted in the book was one that had been held by NLI for many years.  He was very dismayed that he couldn’t have that spot and wanted to know who or what was this NLI?  After a conversation with his dad and Ed Einechen, a friend of the family, he discovered that they were very familiar with NLI.  He also found out his friends Tyler Smith and Judy Barnard were involved with NLI.  It was a natural progression for him to become involved, too.  There is a peaceful feeling he experiences only when he is out in nature and can’t see any sign of man.  He wants to stay on the board as long as possible.
