Blockfields

Blockfield communities are periglacial landforms found on steep mountain slopes in the Blue Ridge Mountains. These communities are here separated from talus slopes in that they are not found immediately downslope from cliff lines. Blockfield communities are more common in the northern Blue Ridge Mountains and up into the glaciated landscapes of the northern Appalachians and are rare in the southern Blue Ridge. Tennessee examples are associated with sandstone, quartzite, and granite geologies. Blockfields can become forested in time and forested blockfields are treated separately here. Open, non-forested blockfields are sparsely vegetated or can be nearly devoid of vascular plants altogether. When vegetated they may be dominated by vines or herbs. Lichens may dominate those that lack vascular plants.
