Places We Protect

Hollenbeck Preserve


Observe grassland birds in the fields or look for wildflowers in the spring.

Why You Should Visit

The site provides habitat for several rare plant and animal species, as well as a significant part of the Hollenbeck River's watershed. This river runs through Robbins Swamp, one of the most important conservation areas in the state, and eventually feeds the Housatonic River. The Hollenbeck Preserve also provides habitat for some of Connecticut's declining grassland bird species.

Why TNC Selected This Site

The chapter purchased this scenic and biologically rich property in 1995 in a bargain sale.

What TNC Has Done/Is Doing

TNC maintains the preserve’s fields, providing habitat for grassland birds. We're also planting elm trees at this site. 

What to See: Plants

The property contains a swamp wooded with a mix of red maple, black ash, white pine and hemlock trees to the north and west and open fields to the south and east. Look for wildflowers in the spring.

What to See: Animals

In the summer, look for grassland birds such as bobolink and meadowlarks in the fields near the trail.
