sharon wander, trustee

Sharon was so inspired by a life-changing wilderness trip to Montana that she abandoned a career as an editor and copywriter and returned to college to pursue a degree in Wildlife Ecology. She met her future husband and business partner, Wade, at Cook College, and both went on to earn graduate degrees from Rutgers University. For her doctoral dissertation Sharon studied the effects of forest fragmentation on breeding Ovenbirds.
Capitalizing both on their degrees and on many years of field experience with the plants and animals of New Jersey, Sharon and Wade then established their own environmental consulting practice, Wander Ecological Consultants (WEC), in 1985. Since then they have conducted endangered species surveys, produced environmental impact statements, performed wetland delineation and permitting, developed mitigation and restoration plans, and provided a variety of other services to a diverse array of clients. As a partner in WEC, Sharon wrote the Natural Resource Inventory for Fredon Township. In the 1990s Sharon and Wade became particularly interested in butterflies, and have since been very active members of the North American Butterfly Association (NABA) – leading field trips and presenting programs for the North Jersey chapter and compiling the Springdale 4th of July count since 1992. As Director of the NABA Butterfly Count Program, Sharon edits the organization’s annual report for some 450 butterfly counts in the U.S., Canada, and Mexico.

She and Wade are especially proud of the butterfly garden at their Fredon Township home, which has attracted a state-record 84 species. Sharon hopes put her knowledge of natural history and her interest in habitat restoration to constructive use for the Ridge and Valley Conservancy.

Susi Tilley, executive Director


Susi Tilley’s passion for the natural world developed during her time growing up in Switzerland where she spent holidays hiking or skiing in the mountains.

After studying Business Administration and working for several years in the private sector, she moved to the United States in 1991, where she married her husband Rich and worked as Vice President of an entertainment lighting and staging company for the next 14 years.

Prior to assuming the role as Executive Director of Ridge and Valley Conservancy Susi served as Development and Outreach Director from 2016-2017.

Susi believes that building a strong conservation organization involves practicing community conservation by building partnerships with other people doing important community work. By connecting people to people, and people to land, her hope is to continue to expand preserved land in the Ridge and Valley Region of New Jersey.

“If you want someone to gain an understanding and appreciation for land protection, expose them to the land, either through recreational activities or through working in it. It is the only way to understand the interconnectedness of all beings in nature. Only then can we bring everyone on board educating them about the importance of protecting land, water, plants and animals which habitat this beautiful area” Tilley concludes. 

Susi lives with her husband and three children in Hardwick, neighboring RVC’s preserves where she enjoys walking her dog, Roxy. She spends her time reading across a wide variety of subjects, practicing yoga with strong women, and enjoying her backyard with family and friends.
