Tacy Fletcher

Tacy Fletcher has found the perfect outlet for her love of nature by volunteering with the Porter County Wildlife Advisory Board, and specifically at the Zona Wildlife Sanctuary. Fletch’s employment in the field of Restoration Ecology and Field Conservation as well as her schooling at Purdue North Central where she is pursuing her Ecology Minor, has prepped her for volunteering in physical work at the sanctuary that includes trail-blazing, trail maintenance, and invasive plant identification and removal.

Earlier this spring she led (over a 3 weekend period) 50 volunteers in a large-scale Invasive Garlic-Mustard Pull Event at the Paul C. Zona Sanctuary. Her future goals of finishing her Bachelors Degree and obtaining certification with the National Association of Park Interpreters are ambitions that motivate her to assist at the board meetings with ideas to help the visitors of the sanctuary be ever more aware of the beauty around them, and their visits more memorable.

Ms. Fletcher is pleased to offer her input whether creative or arduous with important organizations that support native plantlife and at-risk wildlife such as Save-the-Dunes, the Hoosier Chapter of the Sierra Club, The National Wildlife Federation, The Nature Conservancy and our own precious Zona Wildlife Sanctuary.

In Memorium

Linda Knopic (1950 - 2009)

Linda was a very valuable member of our board. Her energy, enthusiasm, and imagination were an inspiration to us all.

Linda volunteered at all of our events for two years before earning her appointment to the board in 2009. She was great with the kids and always made our booth a real hit with the public

Unfortunately, Linda was taken from us very unexpectedly after serving on the board for only two months. It was our privilege to have had her as a board member and friend. She was a true friend of wildlife and we all miss her terribly.

Remember that I truly believe immortality lies with the love you have given. The people we love and the people that love us never leave us. We carry their hearts inside of our hearts forever. Love never dies.
