What's happening at the Watershed in 2026

April

Join us as we learn about our friends the geese. We will explore their behaviors and why they migrate! Classes generally include a craft, hike, and activity for the week’s theme. We spend time outdoors each week, so come dressed in layers and waterproof shoes.

This program is intended for children ages 3-5. Younger siblings are welcome to attend with a parent, but we ask that they do not participate in activities.  Adult attendance and preregistration required- walk ins will not be allowed.

Join us on April 25, 2026 and volunteer to help remove trash from areas around local streams at our 20th Annual Stream Cleanup. Over the past decade, 9,700 enthusiastic volunteers have removed more than 166,000 pounds of trash from our communities. Our cleanup events are a great way to get outside, work together to keep our waterways clean, and improve wildlife habitat.  

Trees NOT Tees! This year we will be offering cleanup volunteers a complimentary tree sapling to say thank you for helping keep our waterways clean! We will not be offering stream cleanup t-shirts as we typically do to reduce our environmental impact and conserve limited natural resources. One cotton t-shirt takes 650 gallons of water to produce while a single oak tree is a keystone species and can host more than 1,000 moth and butterfly caterpillarsIn addition, one mature white oak can absorb over 2000 gallons stormwater per year which can reduce stormwater runoff pollution, flooding, and recharge groundwater.   

We appreciate the continued support of our generous sponsors who make our cleanups possible. Bloomberg, PSEG, Colgate-Palmolive, American Rivers, and New Jersey Clean Communities have provided funding, volunteers and supplies. 

Pre-registration is required! 

Rain or shine event. Please bring your own gloves and (reusable!) water bottle. Long pants and closed-toed shoes are suggested for woodier areas. This is an in-person program. Masks are optional. A parent or legal guardian is required to attend with all children. To attend this event, you must agree to the terms of the waiver included during registration.

Welcome spring and connect with our foraging roots on this delicious hike in search of wild edible plants. 
 
Inspired by the tales of pioneers and Euell Gibbons’ Stalking the Wild Asparagus, naturalist Jeff Hoagland has been enjoying wild edible plants for over 50 years.  We will explore the fields and forest of the Watershed Reserve discovering a wealth of edible plants representing the traditions of our European roots and Native America.  Learn to identify and enjoy a variety of wild edible plants as a rite of spring.
 
Our samplings will include native and non-native species and may include cattail, garlic mustard, violets, winter cress, ramps, spring beauty, wild ginger and much, much more. NOTE – The Watershed Reserve is NOT open to public foraging. 
 
This program is intended for adults. Pre-registration is required.

This occasion is a celebration of YOUR Watershed Institute, recognizing all of the ways that our supporters experience and participate in the Conservation, Advocacy, Science and Education initiatives of the organization.

We will honor outstanding leaders and partners for their invaluable contributions with The Edmund W. Stiles Award for Environmental Leadership and The Richard Rotter Award for Excellence in Environmental Education.

A ginko is a haiku walk, where poets gain inspiration through observation and reflection. Join haiku poet and Naturalist Jeff Hoagland to discover the art of ginko on this communal walk to the Stony Brook. Here we will enjoy a unique habitat and meet a number of organisms up close and personal. The Brook promises discovery and surprise and participants will walk away with some new haiku.

This program is intended for adults and teens. Pre-registration is required.

Ahhhh, springtime! Enter the nocturnal world of frogs as we explore the dark, wet trails of the Watershed Reserve. We will search for frogs, enjoy their serenades, and meet some tadpoles along the way.  We will meet at our pond for a unique adventure of a hike, mud included with admission. 

Ages 6 and up. Adult attendance and pre-registration required.

Date: May 8, 2026 @ 12 p.m. On Zoom

Municipalities throughout NJ are in the midst of developing plans, called Watershed Improvement Plans, to restore NJ’s waters and reduce flooding. As these plans are developed and projects are identified municipalities and their consultants should take a hard look at the types of projects used to address decades of impacts.

The go to techniques of porous pavement and bioretention, while important, may not been the most effective and least costly methods. Techniques that seek to restore and enhance our degraded wetlands, restore stream banks and floodplains, and restore and enhance riparian zones, may offer significant benefits at a lower cost.

Practitioners from RES will talk about their experiences in wetlands restoration and creation for the Pennsylvania DOT to meet its stormwater requirements among other projects. PennDot saved $40 million dollars over the traditional BMPs strategies usually used.

Can NJ learn from this experience? Can restoration and enhancement save NJ municipalities money and improve the environment? Join us on May 8th to learn more.

This event will be 100% virtual. Recordings will be shared with attendees after the event. If you have any questions about the event, please feel free to contact Pri Oliveira at poliveira@thewatershed.org

Meet the neighbors! The Watershed Reserve contains nearly 1000-acres of varied habitats – field, forest, swamp, marsh, pond and stream – all rich with plantanimal, and other life. Each ramble will explore a different trail location on the Watershed Reserve, dictated in part, by weather conditions.  

Celebrate and explore the diversity of life on the Reserve with Watershed Institute staff naturalists, discovering firsthand some of the organisms that make this landscape home.

We will be documenting life along our Reserve’s trails using iNaturalist, a free app available on your phone. iNaturalist is an important resource tool for collecting, mapping and sharing observations of biodiversity. It also has an easy-to-use identification tool that is also backed up by other iNaturalist users.

June

9:00am – 5:00pm

Join us for a day of communion in nature with this gathering of haiku poets on the 950-acre Watershed Reserve in central New Jersey. Under the influence of field and forest, wetland and farmland, and near the song of the Stony Brook, we will celebrate the muse, as we explore, expand and create through the practice of haiku.

Inspiring for seasoned haiku poets and newbies alike, this event will include workshops, readings, music, a haiku marketplace, an open mic and more. We will gather under the large tent at the Watershed Center with time spent on the trail, in the emerging gardens and Butterfly House as well as in the Watershed Center. Morning refreshments and lunch are provided.

When: Wednesday, June 17 from 9:00AM-3:00PM 

Where: The Watershed Institute – 31 Titus Mill Rd, Pennington, NJ

This training is suitable for Department of Public Works crews, facilities staff, or landscape crews and leaders who maintain green infrastructure features like rain gardens, meadows, or naturalized detention basins. 

This workshop provides practical training that crews can apply immediately when maintaining green infrastructure features in your town or at your facility. 

In this workshop, you will learn:

  • How stormwater impacts local waterways

  • Inspection, care, and adaptive management of green stormwater infrastructure

  • Native plant selection and identification for BMPs

  • Common invasive species and management approaches

  • How to read, interpret, and contribute to BMP maintenance plans


Please register soon, as we have a limited number of spots! Registration ends June 10th or when class is full. If you have any questions, contact Olivia at ospildooren@thewatershed.org

This program is provided in partnership with the Chesapeake Conservation Landscaping Council, Kean University, and Mercer County Community College.
