Programs and results

What we aim to solve

SOURCE: Self-reported by organization

Our forest is in crisis. Closter Nature Center is simultaneously faced with unprecedented environmental challenges-- invasive insects killing trees, climate change, erosion, an overpopulation of deer and invasive plants crowding out native species. Within the next few years our forest is projected to lose 1,000 trees or 10% of the forest canopy. It will take much funding and many years to restore the forest ecosystem and ensure its resilience for future generations.

Charting impact

Four powerful questions that require reflection about what really matters - results.

Closter Nature Center's long-term goals are:
-Continue to provide our community with a safe space for all to experience the natural world
-Uphold our mission of conservation-education-recreation though year-round educational programs and events
-Forest Reforestation Project anticipated launch Spring 2024 - a multi-year initiative to restore the forest ecosystem and ensure its resilience for future generations
-Grow and enhance the educational program offering
-Grow our volunteer program
-Increase our visibility
-Increase class enrollment
-Increase our membership rolls
-Increase grant funding
-Increase small dollar donations
-Refurbish the cabin - built in 1967

-To increase our visibility in our community, CNC will utilize direct mail, socials & participate in community events
-Reforestation Project- To address the issues facing the forest we consulted with experts to devise a multi-year reforestation plan. Crucial funding is needed to pay for the reforestation. A fundraising program and multi-faceted marketing campaign has been developed and will include eg. website,, socials, direct mail, email, press release, etc.
-To refurbish the cabin we will seek grant funding, including the prospect of naming rights, corporate sponsorship and donations from our community
-Increase our fundraising efforts

Because funding will be critical to our endeavors, our newly hired (Jan. 2024) full-time Executive Director will focus on securing grant funding, from identifying prospective grant makers through to the grant application submission process. In addition, he will develop other avenues of fundraising such as special events as well as grow our educational program offering and volunteer programs. Closter Nature Centers part-time on-site naturalist runs the education programs on-site and at local schools.
To maintain the grounds and ensure the successful daily operations, Closter Nature Center relies heavily on volunteers as well as our hands on board members. From leading trail maintenance and guided hikes, to planning the education programs and schedule, to publicity and marketing, our volunteers and board members are crucial to our operations.

-Newly created full-time position of Executive Director was filled in Jan. 24 and training is underway
-Reforestation: We have retained experts to evaluate and develop a multi-faceted long-term plan for restoring the forest. Work has begun through clearing of felled trees and installation of plantings coupled with deer exclosures- a necessary element to protect each newly planted sapling for the first few years. A multi-faceted marketing campaign is in development.
-Completed a Direct Mail campaign in support of our Fall '23 education programs. The DM campaign was made possible by a grant from Rockland Electric

Balance sheet

Fiscal Year: May 01 - Apr 30

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
