Native Meadow Garden coming to Mt. Lake

The Liberty Twp. Environmental Commission is thrilled to announce it received a grant award from ANJEC through their Open Space Stewardship Grant Program to create a native meadow garden at Mountain Lake. At the heart of Liberty Township is Mountain Lake; Warren County’s largest, natural glacial lake and an Audubon designated Important Bird and Birding Area.

Through the ANJEC grant, the Environmental Commission will design and plant a 400 square foot wildflower and grass meadow near the pavilion at Mt. Lake to support our wildlife. Once complete, the garden will serve as a self-guided tour of native plants, their beneficiaries and why they are so important in our community.

Bear Awareness Fact Sheet

New Jersey is home to all kinds of beautiful wildlife – including black bears.

Black bears are getting a lot of attention these days, for the wrong reasons. They're venturing too close to homes and into backyards, looking for food. Bears that look for food near your home or in your yard likely have learned bad habits from people who feed them intentionally, or unintentionally by carelessly leaving out food or garbage.
