Sheltered coves and north-facing cliffs are hemlock habitats in Eastern Kentucky. This map shows range of elevation change within a 164-foot square area. Red areas indicate the highest relief, which are mountain slopes in the coal fields, and cliffs along the Pottsville Escarpment and Pine and Cumberland Mountains fault. Since most cliff is sandstone, areas indicated as cliffs would presumably have sandy soils, which is a condition for other evergreen species habitats, e.g., mountain laurel and rhododendron.
This is first-run test. Further analysis would include adding aspect, evergreen canopy cover, and soils to better refine predicting hemlock habitat.
