The tall pines provide great habitat to birds of prey, specifically owls, such as the Eastern Screech Owl and the Great Horned Owl. Woodpeckers, such as the Red-bellied and Downy, can be found searching for insects in dead and decaying tree trunks.

Meadow Brook is an area surrounded by a multitude of neighborhoods and includes the Millvale Reservoir. The reservoir itself was created in the late 19th century to support the growing population of Haverhill, which was around 10,000 by the time of the Civil War.

The park and conservation area play host to various plants and wildlife. White Pine grows in abundance here and can be found on both sides of the reservoir. Poison Ivy can also be found here both on the ground and growing up the trees. There are also a couple of large oak trees next to a vernal pool. The reservoir, like other bodies of water in the area, is pumped into Kenoza Lake to be used as drinking water for the city. You can also find a dam that was built around the time the reservoir was built.
