For 51 years, the 383 picturesque acres of For-Mar Nature Preserve & Arboretum have been wowing visitors, protecting wildlife and nurturing the environment. This former dairy farm was donated by Forbes and Martha Merkley to create For-Mar, which opened in 1970. Scattered throughout the grounds are meadows, ponds and plenty of trees. Hikers enjoy numerous miles of trails and our collection of gardens.

Our expansive 116 acre Arboretum is Level II Accredited by ArbNet

and contains over 1800 woody specimens representing 157 species (as of 2015).  Many, but not all are labeled.

Today, you can celebrate the spirit of Forbes and Martha by exploring the wetlands, fields and forests of this great park. Rich educational experiences can be had all over our grounds.

In our Visitor’s Center, get a hands-on experience with live animals and learn how flora and fauna coexist in a healthy ecosystem.

If you’re an educator, take a field trip with your school and explore Kearsley Creek as it twists through the park. Sign up for a guided walking tour with one of our naturalists today and learn how you can experience the great outdoors in a whole new way.

For-Mar is home to Nature’s Superheroes, The Preservers. Visit their Superhero Headquarters – our new barrier free treehouse. You might even get lucky enough to catch a glimpse of one at a program or event – but remember, just like other superheroes, they only make appearances when they are needed. To download their comic book stories, visit our brochures and flyers download page.
