PMI Tract

Fredon Township, Sussex County, NJ


Located south of Newton, New Jersey and north of Whittingham Wildlife Management Area.


US 80 west to the exit for Route 206 north. Turn left on Route 618 in Springdale; pass by an entrance for Whittingham Management Area.  Turn right at the stop sign onto Ridge Road (Route 519) north. Most of the property is located on the right hand side (east side) north of Meadow Lane and south of Douma Drive (north of green mileage marker 63). At the northern end, at the end of the field is a informal trail one can hike.

On the opposite side (west) of Route 519 is the land of Valley View Farm which can also be hiked. 


Previous owners of PMI had applied to the Township for approval to construct 183 patio homes and 18 single-family residences and a wastewater treatment facility.

2001 (June)  --  The Nature Conservancy acquired the property at about $11,000/acre.

Nearby is Valley View Farms, a 198-acre property with similar characteristics. TNC purchased the property in October, 2000, for approximately $14,000/acre.


wooded uplands, limestone ridges, and agricultural fields (it serves as a major groundwater source for the nearby Muckshaw Ponds)


7/09/04.  Headed south and southwest along the side of the field by the woods edge.  Came to a powercut; descending south; still heading southwest with a field on the left (private property); at a fork in the path I go left (south); up and along a  ridge; came to a side path on the left and decided to take it.

Walked through a field being overtaken with autumn olive; busted through to a T-intersection; go right (northwest); heading uphill; the path took me in a loop back to the shrubby field and then back to the fork from which I started.

Back on the original trail I take it for a short walk but it dead ends suddenly (if one climbs uphill, as I did, one will come to someone's backyard); turned around heading back to the fork in the path.

Heading back and seeking a different return path to the parking area, I took a left fork heading away from the agricultural fields below. Came to another backyard.

Retraced my steps and then saw a beautiful mowed lawn path between two hedges; I had my doubts that the path would take me back, but walked on it anyway, because it was so pleasant looking; see a church steeple in the distance; what do you know  -- I arrived back at the power cut; took a left turn and walked uphill along the field back to the parking area.
