Summer Lake Area – Oregon Conservation Strategy

This area is comprised of Summer Lake and the surrounding high desert wetlands subregion, including much of the Diablo Mountain Wilderness Study Area.

COA ID: 189

Recommended Conservation Actions

Improve water delivery system within the Summer Lake area to improve effectiveness of wetland management.
Maintain diverse wetland habitats.
Manage livestock grazing to promote healthy wetlands and riparian areas.
Promote early detection and suppression of invasive weeds.
Remove and control juniper encroachment into sage habitat.
Restore and maintain complex, continuous sage habitat.

Ecoregions

East Cascades

The East Cascade ecoregion extends from the Cascade Mountains’ summit east to the warmer, drier high desert and down the length of the state. This ecoregion varies dramatically from its cool, moist border with the West Cascades ecoregion to its dry eastern border, where it meets sagebrush desert landscapes.

Northern Basin and Range

The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats.

Strategy Habitats

Aspen Woodlands

Aspen woodlands are woodland or forest communities, dominated by aspen trees with a forb, grass, or shrub understory. Aspen woodlands can also occur within conifer forests.

Natural Lakes

Natural lakes are relatively large bodies of freshwater surrounded by land. For the purposes of the Conservation Strategy, natural lakes are defined as standing water bodies larger than 20 acres, including some seasonal lakes.

Ponderosa Pine Woodlands

Ponderosa pine woodlands are dominated by ponderosa pine, but may also have lodgepole pine, western juniper, aspen, western larch, grand fir, Douglas-fir, mountain mahogany, incense cedar, sugar pine, or white fir, depending on ecoregion and site conditions. Their understories are variable combinations of shrubs, herbaceous plants, and grasses.
