JOHNSONBURG LIMESTONE CLIFFS

Warren County, NJ


Directions:

From NYC take I-80 west about 55 miles to exit 19. Coming off the exit ramp, cross over Route 517 and drive into Allamuchy. Take the second left, Johnsonburg Road, which goes northwest. (In Quaker Church the road jogs right). After 7.5 miles turn northeast (right) onto Route 519 and drive into Johnsonburg, 0.2 miles. At the intersection of Routes 519 and 661, continue straight on Route 661 and drive 0.2 mile, crossing under the railroad tracks. Turn west (left) immediately on Kerrs Corner Road and drive 0.3 mile to a rough dirt road on the left leading up to the old railroad station. Park by the station and walk westward (right as you face the tracks) about 0.5 mile along the tracks until you come to a cliff on your left. Limestone cliffs on either side of abandoned railroad.


The name Johnsonburg refers to an early postmaster.

A small pond surrounded by a sedge mat, and this in turn surrounded by a deciduous swamp.

The outer fringe was composed of numerous limestone outcrops. Eriophorum viridi-carinatum cotton sedge, was scattered among the tall grasses. Carex flava was truly abundant. Also abundant was bog buckbean. Epipactis continues to spread in the areas where lime occurs.

JOHNSONBURG, WARREN COUNTY, NJ
June 26, 1961

The area visited was in the limestone region of Warren County. It consisted of a small pond surrounded by a sedge mat, and this in turn was surrounded by a deciduous swamp. The outer fringe was composed of numerous limestone outcrops. Investigation might profitably be held in the area next year in late May. The cotton sedge, Eriophorum viridi-carinatum, was scattered among the tall grasses most of which went unidentified. Carex flava was truly abundant as was the bog buckbean, nowhere in New Jersey have I seen as much of the latter. Epipactis continues to spread in the areas where lime occurs. (The source of lime may be quite unnatural, for Louis E. Hand located a station for the hellebore orchid at Medford Lakes, Burlington County, in which the lime source was a discarded bag of cement!) Seven species of orchids were located without special effort expended. The Carolina wren was the bird which excited the most interest.

Among the plant species observed were;
Cystopteris bulbifera
Camptosaurus rhizophyllus
Asplenium trichomanes
Pellaea atropurpurea
Pellaea glabella
Eriophorum viridi-carinatum
Cladium mariscoides
Carex flava
Chamaelirium luteum
Trillium cernuum
Cyprepedium parviflorum
Cyprepedium reginae
Calopogon pulchellus
Pogonia ophioglossoides
Epipactis helleborine
