    Deer Exclusion Fencing Complete!

    With the Borough's support, and tremendous dedication from almost three dozen hard workers, installation of fencing for three deer exclusion sites is complete! 



    Cabling, 2019


    Seven CNC trail maintenance volunteers, Dr. Jay Kelly and 6 students from Raritan Valley Community College, plus 20 young people from the Closter Nature Center Summer Program, installed 6,600 feet of fencing (a total of 1 1/8 miles!), enclosing 30 acres of our 136 acre nature center.  This will keep the deer out of certain areas so the forest understory and young trees can recover from many years of deer browse, and survive to shape our future forest.




    With Naturalist Director Marc Gussen, board members Joel Rudin and Beth Ravit attended the Mayor & Council meeting on Wednesday, August 14thto thank the Borough for their financial support for this project, and to let them know the fence is installed.

  • Forest Stewardship Project

    Forest Stewardship Study

    Starting in 2015, the Closter Nature Center (CNC) Board undertook a long-term project to assess the health of its 136-acre site of forested wetlands. Soon after, a forest stewardship study was conducted by New Jersey Audubon for the CNC which has served as a baseline for further study and recommendations of care. Please check here for continuing updates and information. (Note: Most recent information appears first.)

    Woodland Stewards Worry About Deer Impact

    Following is a link to an article in the Northern Valley Press published August, 2019. 

    NORTHERN VALLEY AREA, N.J.—While a regional approach to deer population control remains a major theme among Pascack and Northern valley municipalities—save for Saddle River and River Vale now planning fall 2019 bowhunts—managers of several area nature sanctuaries warn that an overpopulation of deer is causing long-term impacts to forests and biodiversity—and they are taking action.

    EAB Monitoring Stations

    Look UP! You may notice these green, cylindrical cones hanging from a tree in the Nature Center. These are monitoring traps for the Emerald Ash Borer (EAB), an invasive beetle that is impacting Ash trees in our region. Tracking the path and impact of these beetles is important to understanding the changing nature of our forests. Monitoring invasive species is part of our ongoing Forest Stewardship Project at the Closter Nature Center. These stations were put in place by local volunteer, Todd Bradbury.

    Assessing Forest Health in Central New Jersey

    White-tailed Deer

    The Closter Nature Center held its Annual Meeting on Wednesday, May 2nd, 2018 at 7pm. in the log cabin by the pond. There was a brief business meeting highlighting our past year followed by a presentation on "The Impacts of Deer and Invasive Species on Forests in Northern-Central New Jersey.

    Dr. Jay Kelly from Raritan Valley Community College presented the results of his research on the impacts of overabundant deer and invasive plant species on forests in northern-central NJ. Since 2014, he and his students have studied over 135 forests, primarily in the Raritan Watershed, documenting how tree regeneration and other aspects of forest understories have changed since the mid-Twentieth Century, when deer and invasive plants were much lower in the state. They also studied the effectiveness of different strategies for forest restoration, including exclosures and deer management programs, at improving forest conditions over time. The goals of this research are to provide real-world research opportunities for students, and to provide local communities with information needed to understand these important issues; showing what is happening to our forests, and what can be done to address them.

  • Eagle Scout Project

    Patrick Lee’s Eagle Scout Project

    Over the years, the Closter Nature Center has been the recipient of projects completed by Boy Scouts attempting to become "Eagle Scouts". This recognition is not come by easily, it is something the Scouts earn by building skills and learning how to become leaders. By building a bridge at the Nature Center, Patrick Lee earned the right to be called an "Eagle Scout", the highest rank in scouting. 

    Here is a copy of Patrick Lee's presentation to the Board of Trustees.

    Good evening board members, leaders, scouts, and parents.

    My name is Patrick Lee and I would like to thank the Nature Center for allowing me to complete my final steps toward Eagle Scout here at the nature center. The Nature Center holds a special place in my childhood. When I was a little boy I would spend a lot of time here fishing and attending camps, I especially enjoyed the fishing derbies. For my project, we replaced the main bridge. The previous bridge has been there for as long as I could remember, and it needed to be replaced. The new bridge now has steps for easier access, a handrail & is much sturdier.

     I would especially like to thank Mr. Gussen, working with him was a great experience. A special thank you to Mr. Mattes, who has been my leader since the first day of cub scouts in first grade, all the way up to Eagle Scout in my senior year of high school.  Also thank you to Dr. Baron, who worked with me every step of the way throughout my project. Thank you to the scouts, parents, and leaders who helped on my work days, and generously donated time, energy, efforts, and funds to my project, without them this wouldn’t happen. And a huge thank you to my Father and Grandfather for helping and teaching me the carpentry side of this project. Additionally a thank you for the Sapper family for creating this giant check, of which is the remaining funds of my fundraising efforts for the bridge. I am proudly able to donate $730.15 to the Closter Nature Center, so that it can continue to be a special place for other Closter children as they grow up.

  • Technology Upgrade

    Help us, help you!

    The Closter Nature Center is working to upgrade its technology infrastructure to more easily meet the needs of our community. We are migrating class registrations and some back office functions to CommunityPass, a cloud-based registration and payment software based in Ridgewood, New Jersey. In order to fully migrate our membership database over to CommunityPass, there is a setup fee of $1000.00. We welcome any donations towards that goal.

    Thank you!
