Mariton Wildlife Sanctuary

On Wednesday, October 21, I visited the Mariton Wildlife Sanctuary, one of 42 preserves in eastern Pennsylvania and southern New Jersey protected by the Natural Lands Trust (NLT), a regional land conservancy.  The visit was a special treat for members of NLT's White Oak Society; anyone who has been a NLT member for 10 years or more continuously is automatically enrolled.

The Mariton Sanctuary is managed by NLT employee Tim Burris.  Tim used to be the head naturalist for my organization, but he moved on one year after I took my job here in 1988.  (Do you think it was something I said...?)  Tim and I have remained friends and colleagues since he left, but I hadn't seen him in quite a few years.  We gave each other big bear hugs when we got reacquainted.

Trail to the Delaware River Overlook

The Mariton Sanctuary is located in extreme southeast Lehigh County, Pennsylvania, right along the Delaware River, about 1.25 hours north of my preserve.  The eastern boundary of the sanctuary drops precipitously to the river road paralleling the Delaware.

"Mariton" is a contraction of the names Mary and Tony, the first names of the couple who owned the property and set it aside for conservation.  Tony and Mary originally bought 38 acres of overgrown agricultural fields and kept adding land as it became available until, by the time they died, they had accumulated 200 acres.  The surrounding countryside is more developed than it was when Tony and Mary owned the land, but now it would be fair to characterize it as exurban - a refuge caught between the sprawl of Philadelphia and the former industrial cities of the Lehigh River valley (i.e., Allentown, Bethlehem, and Easton, Pennsylvania).  

Stone wall in the woods

The sanctuary is perched on the top and eastern flank of a Brougher Hill, a very rocky knob.  Much of the land had been cleared for agriculture, and stone walls constructed of the stones removed from the fields criss-cross the property.

American chestnut leaves

American chestnuts, both naturally occurring as well as some planted by Tony, occur throughout the property.  Tim told us that one technique that early chestnut restorationists tried to prevent chestnuts from dying of the chestnut blight fungus was irradiating chestnuts before planting them, hoping that the zap of radiation would protect the trees.  Of course, the irradiation didn't work (since the fungus is in the soil, not on the chestnuts).  But, some of the irradiated nuts that Tony planted have grown into 25-foot-tall trees that are producing abundant nut crops.

Tim manages much of the sanctuary in fields and brushy young shrub habitat.  Sassafras trees are abundant in these brushy patches.

The day was almost perfect - low humidity, clear blue skies, good fall color.  If I had any complaint, it was that it was a bit too warm; we had temperatures above normal in the mid-70s.
