General Rhododendron Thickets and Balds
No image for this habitat.
Habitat Overview
Dense and extensive thickets composed of Rhododendrons are conspicuous features of acidic coves in the mountains, where they are commonly referred to as "Rhododendron Hells". Rhododendrons also grow out in the open on high elevation heath balds. A few relict populations -- survivors from a wider Ice-Age distribution -- also cling to a few steep, north-facing slopes in the Piedmont.
