    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! 
    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 14th to thank the Borough for their financial support for this project, and to let them know the fence is installed.

    ----- SUMMER PROGRAM NOTES -----

    The summer program was a huge success this year! We had 25 amazing volunteers helping with our summer classes. 

    Thanks so much to Brielle, Christian, Christina, Derin, Elena, Eric, James G., James S., Jay, Jonathan, Josephine, Kevin, Liam, Luke, Marin, Mia, Natasha, Noah, Olivia, Reese, Rhett, Shauna, Sienna, Sohyun, and Zach. Without them, our summer classes would not have been possible. These wonderful volunteers made this summer filled with memories and great experiences. We hope they learned and grew, and most importantly: had fun!

    Special thanks also to Adri Lindgren for letting us visit her animals and hosting a wonderful end of the year party. This summer is definitely marked in everyone’s calendar as the Best Summer Ever!

    Saturday, May 5th 8:00- 10:00 AM

    Come join the "early birds" at the Nature Center cabin from 8:00 to 10:00 Saturday morning, May 5th, for a birding adventure with Naturalist Nancy Slowik.  While seasoned birders are welcome, no experience is required. A pair of binoculars is most helpful.  A few extra binoculars will be available for those not able to bring their own.  We will start indoors for some pointers and to see images of the wide variety of birds we hope to spot out on the trails.

    This program is geared to adults, but interested young people are welcome.  The walk portion will last about one hour.  Free for members, $5 for non-members. 


    Wednesday, May 2nd - 7 PM AT THE CABIN

    Impacts of Deer and Invasive Species on Forests in Northern-Central New Jersey

    Dr. Jay Kelly from Raritan Valley Community College will be presenting 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.

    Jay F. Kelly, Ph.D. is an Associate Professor of Biology and Environmental Science at Raritan Valley Community College, where he teaches a wide variety of ecology, botany, zoology and environmental science courses. He holds a BA in Biology and a PhD in Ecology & Evolution, both from Rutgers University. His research interests are the biology and conservation of rare plant and animal species, coastal and forest ecology, and the design and implementation of ecological land management practices that balance the needs of humans with other species in the landscape. His other research interests include plastic marine debris, historical ecology, human ecology, and toxins in consumer products. Dr. Kelly attempts to develop community-based research projects and partnerships that benefit both his students and the communities they serve. He received a Certificate of Special Congressional Recognition for his research and service in 2010.

    Our Thanks go out to the many generous souls who contributed more than 25 homemade soups to our delightful Soup Supper. In addition, The Barn, Closter One, Madeline Petit Paris, La Promenade and Zendiggi all donated soups, and Balthazar Bakery contributed bread! All were delicious!  By the end of the cold, rainy afternoon, (perfect for enjoying soup!), we’d had a warm, friendly and very well attended Soup Supper!
