Woodlands
.
Woodland habitats include closed-canopy forests (deciduous, coniferous, and mixed) and more open habitats with trees (pine and oak savannas and pinyon-juniper forests). About a third of the continental United States is covered by woodlands, down 30 percent from pre-European times; most losses have been in the East. Woodlands are at risk of unsustainable logging, plantation forestry, overgrazing by deer or livestock, new tree diseases, invasive species, conversion to agriculture, too-frequent or too-scarce fire, resource extraction, urbanization, and fragmentation by roads and utility lines.
