Dendro-Detectives! Towering over our heads, trees often escape our attention despite seeing them every day. For this program, we take trees out of the background and into focus as we learn about common species, life cycles, reproduction, survival strategies, seed dispersal, fall colors and more. Lessons are active and outdoors, using our forest as both a classroom and a playground. 

This active outdoor program incorporates games and group activities in addition to STEM lessons about tree biology and forest ecology. We will play games that focus on teamwork and socializing and games to get to know the trees! Some hands-on STEM activities we will be doing include leaf chromatography, creating tree field guides, extracting tree cores for dendrochronology, measuring tree size and height across plant communities, and more

Programs will be held outdoors on our beautiful 152 acre property in the Highlands region of northern New Jersey. Our outdoor facilities are ideally suited to outdoor learning, and include a picnic grove, recreation field, covered pavilion, fire circle, hiking trails, raingarden, butterfly garden and a brook.​
