The more common native bird species found here include the American crow (Corvus brachyrhynchos), American robin (Turdus migratorius), gray catbird (Dumetella carolinensis), yellow warbler (Dendroica petechia), common yellowthroat (Geothlypis trichas), song sparrow (Melospiza melodia), northern cardinal (Cardinalis cardinalis), and red-winged blackbird (Agelaius phoeniceus). These bird species may be found in all three major habitat types within the historic site. These habitat types are broadly classified into landscaped areas, wetlands, and riparian woodlands.

To help understand the exact age of the Iron Works House the National Park Service recruited the help of dendrochronologists. These scientists drilled out small sections of the framing of the house. By looking at the width and pattern of the trees growth rings and comparing it to other trees of the time it is now believed that the house was built around 1688 or 1689.
