Amy Jacobs

 Amy Jacobs, Agriculture Program Director

“It’s rewarding to work for an organization with a mission I believe in and in collaboration with many wonderful colleagues.”


Joe Fehrer

Joe Fehrer, Coastal Communities Project Manager

Joe grew up near Nassawango Creek Preserve and began his Conservancy career in 1978 as a volunteer.  He works with local and community partners on the Eastern Shore to address issues around climate change and sea level rise, and with state and regional partners to advance land protection and restoration efforts in both Maryland and Virginia.

“Making a positive difference and achieving tangible and lasting results is very important to me. Working with dedicated colleagues and partners gives me great hope for the future."

Deborah’s efforts focuses on ecological restoration at more than 30 Conservancy preserves across Maryland/DC and reaching into West Virginia, working to return natural processes – like fire – to the landscape to help maintain healthy, resilient natural systems.

"Sometimes I get satisfaction very quickly from my work, but other projects, like tree planting, will take years to see results. It’s very satisfying to know that I can do these long-term projects and they’ll continue on and on."
