Vegetation of vernal pools and related ephemeral wetlands in the Gerber Block, Klamath Basin, Oregon, including searches for Orcuttia tenuis and Tuctoria greenei

Creator:: Björk, Curtis R.
Abstract:: The California vernal pool-endemic grasses Orcuttia tenuis and Tuctoria greenei, both listed under the U.S. Endangered Species Act, were recently found in Modoc County, California, a short distance south of the Oregon border. This prompted searches in suitable habitats in adjacent portions of the Klamath Basin in Oregon, in the...

Use of a rainfall-runoff model for simulating effects of forest management on streamflow in the east fork Lobster Creek Basin, Oregon

Creator:: Nakama, Lenore Y., Risley, John C., and United States. Bureau of Land Management, Geological Survey
Abstract:: The report describes the results of model calibration and validation, and evaluates the extent to which runoff response to timber harvesting and increased road densities in East Fork Lobster Creek Basin can be simulated, using Precipitation-Runoff Modeling System (PRMS), a deterministic, destributed-parameter-modeling system.

The Distribution and reproductive success of the Western Snowy Plover along the Oregon Coast - 2012

Creator:: Lauten, David J., Castelein, Kathleen A., Farrar, J. Daniel, Kotaich, Adam A., and Gaines, Eleanor P.
Abstract:: From 5 April – 21 September 2012 we monitored the distribution, abundance and productivity of the federally Threatened Western Snowy Plover (Charadrius nivosus nivosus) along the Oregon coast. From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes Overlook, North Tahkenitch Creek,...

Classification of oak vegetation in the Willamette Valley

Creator:: Buechling, Arne, Alverson, Ed, Kertis, Jane, and Fitzpatrick, Greg
Abstract:: A plant community classification was developed describing the comprehensive variation of oak vegetation currently occupying the Willamette Valley Ecoregion of western Oregon. Multivariate statistical analyses were used to classify field collected floristic and habitat data. Field sampling targeted minimally managed, homogenous vegetation stands with a significant oak component occupying at...

Major-ion, nutrient, and trace-element concentrations in the Steamboat Creek Basin, Oregon, 1996

Creator:: Rinella, Frank A., Geological Survey (U.S.), United States. Forest Service, and Douglas County (Or.)
Abstract:: This report presents the concentrations of major ions, nutrients, and trace elements in water and bottom sediments collected in the four-tributaries during the low-flow condition of September 9-13, 1996. Stream-water chemistry results are contrasted, and trace-element concentrations compared with U.S. Environmental Protection Agency chronic aquatic life toxicity criteria. Bottom -sediment...
