VALUABLE LESSON: Never make assumptions! Always do your research, ask questions, make contact, do…read morethe work to find out what's up! (more on this below)
I was FASCINATED to explore the various State-Line Serpentine Barrens in Southeastern PA. This is a rare area of genuine savanna habitat, right here in Penna!
This habitat came about b/c Native Americans used fires to clear vegetation, so that only grass would grow, which would attract grazing animals to hunt. They practiced this fire setting from NY to MD & on down to AL. With nothing to retain moisture, a savanna habitat formed & Cactaceae vegetation grew. When Europeans settled the area, the desert was cultivated for farm & settlement use, so the habitat changed once again.
The few areas of serpentine barrens that remain (60 sq mi), have been protected by The Nature Conservancy since 1979. They maintain the land with controlled fires, just as Native Americans did. Thin soil lies on a bedrock of serpentine stone (light-green in tone). It has high levels of nickel, chromium, etc. that are toxic to most plants/animals. Living here, are rare & endangered species, that evolved over thousands of years in adaptation to the unique habitat. The serpentine aster here does not exist anywhere else in the world. Other rare plants are: the round-leaved fameflower, & hairy chickweed.
The serpentine barren ecosystem relies on periodic fire to destroy forest & certain plants that begin to invade. Fire opens the land to prairie grasses, wildflower meadows, pitch pines, & diverse types of ferns. This attracts a number of moths & butterflies (cobsew skipper, red-banded hairstreak, mottled duskywing, barrens buckmoth & dusted skipper), as well as birds (barred owl, declining whippoorwill, several warblers, bobwhite quail, etc.).
There are various pockets of serpentine barrens in the SE PA area, but not all are public. Also, each site has different hours / accessibility requirements, but among the public ones, there is access for hiking, horseback riding, & bird watching.
- Goat Hill (602 acres co-owned with Pennsylvania's Bureau of Forestry)
- Chrome (390 acres co-owned with Elk Township)
- Nottingham (630 acres owned by Chester County)
- Rock Springs (170 acres owned by Lancaster County Conservancy and private owner)
- Texas (210 acres privately owned)
- Pilot (92 acres co-owned with a private owner)
Chrome looked the most promising public option from what I read on the Nature Conservancy website. I did contact another Yelper who had reviewed another barren, but he was unsure where to go b/c he visited through his U-Penn Geology Grad program. So I planned for Chrome, expecting to have to hike a ways to get to a savanna clearing, but that it would be pretty straightforward.
Why it's important to COMMUNICATE:
First, it is easy to drive past the trail b/c there is no street signage. (I posted a pic of the entrance to help others.) Gravel lot, not super big. It's very wooded all over. There was no trail map, just a sign stating you were at the Chrome Serpentine Barrens. The trails were marked clearly, but were a mix of dirt & grass (up to 10" high) that needed mowing. The area, ironically, was extremely wet / muddy, with mosquitoes so bad I could barely keep my eyes open. I had my son on my back, & he suffered the bugs as well. We hiked for 15 minutes down the most promising trail, but came nowhere near a clearing. I was expecting to rise a little in elevation to escape the stagnate puddles & mud, but that didn't happen. I studied the tree canopy for clearings, but the canopy, & ground-level visibility gave no hint of a clearing anywhere along the approx 0.6mi I hiked into this barren. Unfortunately, the bugs were just too prolific to bear, so we retreated & left.
I always give trails or greenspaces at least 4 stars on Yelp, so I will do the same for this place, however, MUCH better communication is needed to disclose what is going on here. Where are these charming plains with frolicking birds & Cactaceae? If they're a 2mi hike in, could someone explain that? Could you show me which trail will lead me there?
I made wrong assumptions about the info that would be presented at the trailhead, & about the feel of the trails themselves. I definitely need to contact The Nature Conservancy directly, & I will shoot an email to an admin at Penn's Geo program as well. I'll update if/when I have more info.
For now, if you're headed there, be prepared to SLATHER yourself in bug repellent, wear high socks to guard against ticks on the unmowed trail, hiking boots to wade through mud, stamina to hike a while, & low expectations, b/c it's very unclear where/when you will ever discover these elusive mythical plains!
I have a feeling that if I had communicated with people in the know, I'd have been led to AMAZING sights, like the pics the other Yelper took, instead of fumbling around in the miserable haze of mosquitoes & mud, only to reatreat home, unsatisfied, & annoyed!
