Poison ivy needs a fair amount of sunlight to survive. Around here, it is most often seen in prairies, savannas, open islands within marshes, floodplain/bottomland forests, and forest edges, and persists for a while in forests with numerous or large forest openings, forests with less dense or fairly open canopies, or in second growth forests for up to 30 years after canopy closure. As far as disturbances, it seems to do best in areas where the major human "disturbance" is actually fire exclusion and control.

As for poison ivy, it's considered to be non-native here. They say that the Pine Barrens is normally too acidic for it to thrive. But it can be found in populated areas, and in ghost towns and other areas of past human disturbance.

The grove is located between the Blue Ridge Parkway and Hendersonville Rd ( Hwy 25 ) near where the parkway crosses over 25. I call it the Ramble Grove because of the nearby Ramble housing development located nearby. http://www.nativetreesociety.org/fieldtrips/north_carolina/20090125-blueridgeparkway/mountainstosea_trail.htm The grove is dominated by Eastern White Pine but also contains Tuliptree and Pitch Pine with American Holly as an understory tree. A few oaks and shortleaf pines are found here too, especially near the borders of the grove. Large Poison Ivy vines also climb to great heights into the trees. I found one huge vine that was two feet in circumference! Why do some forests have large Poison Ivy vines while others lack Poison Ivy all together? Poison Ivy seems rare in most older growth forests I visit while it seems more common in younger forests. Especially near populated areas. Does anyone know why? I would guess this grove to be young judging by the trees youthful appearance and many branch stubs on the trunks of the pines. I would guess the grove at 60-80 years old. The tallest tree found today was a respectable White Pine that was 143..2 feet tall and 6' 3" in girth. Tall and slim. The largest overall was a Tuliptree that was 138.3 feet tall and 8' 9" in girth. Also a hollylike plant was found in the forest that I believe is an invasive species. Can anyone identify this " mystery holly " for me? I have seen it as an ornamental in people's yards. I think my dad has one.. I don't think it is a true ilex. Here are todays measurements cbh Height White Pine 6' 3" 130.3' White Pine 8' 0" 122.6' White Pine 6' 2" 136.5' Tuliptree 8' 9" 138.3' White Pine 6' 3" 143.2' ! Pitch Pine 5' 6" 114.3' ! It was a good day but my hands were about frozen when I got out of the woods!
