Unearthing Secrets of the Forest
Forests are a defining feature for large areas of the Pacific northwestern United States from northern California to Alaska. Coniferous temperate rainforests in the western Cascade and coastal mountain ranges are appreciated for their aesthetic value and abundant natural resources. Few people recognize the riches beneath the forest floor; yet, soil is a key ecosystem component that makes each type

Prairie Monitoring Protocol Development: North Coast and Cascades Network
The purpose of the project was to conduct research that will guide development of a standard approach to monitoring several components of prairies within the North Coast and Cascades Network (NCCN) parks. Prairies are an important element of the natural environment at many parks, including San Juan Island National Historical Park (NHP) and Ebey's Landing National Historical Reserve (NHR). Forests

Final Report for Emergency Stabilization and Rehabilitation Treatment Monitoring of the Keeney Pass, Cow Hollow, Double Mountain, and Farewell Bend Fires
A strategy for monitoring post-fire seedings in the sagebrush steppe of the Intermountain West was developed and used to monitor four example fires in the Vale, Oregon District of the Bureau of Land Management (BLM). We began to develop a potential approach by (1) reviewing previous vegetation monitoring manuals produced by the Federal government to determine what techniques and approaches had bee

Investigating Seed Longevity of Big Sagebrush (Artemisia tridentata)
The Intermountain West is dominated by big sagebrush communities (Artemisia tridentata subspecies) that provide habitat and forage for wildlife, prevent erosion, and are economically important to recreation and livestock industries. The two most prominent subspecies of big sagebrush in this region are Wyoming big sagebrush (A. t. ssp. wyomingensis) and mountain big sagebrush (A. t. ssp. vaseyana).

A Chronosequence Feasibility Assessment of Emergency Fire Rehabilitation Records within the Intermountain Western United States - Final Report to the Joint Fire Science Program - Project 08-S-08
Department of the Interior (DOI) bureaus have invested heavily (for example, the U.S. Bureau of Land Management (BLM) spent more than $60 million in fiscal year 2007) in seeding vegetation for emergency stabilization and burned area rehabilitation of non-forested arid lands over the past 10 years. The primary objectives of these seedings commonly are to (1) reduce the post-fire dominance of non-na

Pinon and Juniper Field Guide: Asking the Right Questions to Select Appropriate Management Actions
Pinon-juniper woodlands are an important vegetation type in the Great Basin. Old-growth and open shrub savanna woodlands have been present over much of the last several hundred years. Strong evidence indicates these woodlands have experienced significant tree infilling and major expansion in their distribution since the late 1800s by encroaching into surrounding landscapes once dominated by shrubs

Forest Vegetation Monitoring Protocol for National Parks in the North Coast and Cascades Network
Plant communities are the foundation for terrestrial trophic webs and animal habitat, and their structure and species composition are an integrated result of biological and physical drivers (Gates, 1993). Additionally, they have a major role in geologic, geomorphologic and soil development processes (Jenny, 1941; Stevens and Walker, 1970). Throughout most of the Pacific Northwest, environmental co

Dust deposition effects on growth and physiology of the endangered Astragalus jaegerianus (Fabaceae)
Human expansion into the Mojave Desert is a significant threat to rare desert plants. While immediate habitat loss is often the greatest concern, rare plants situated near areas where soil surfaces experience frequent disturbance may be indirectly impacted when fine particulate dust accumulates on leaf surfaces. Remaining populations of the federally listed Astragalus jaegerianus (Lane Mountain mi

Data from the 2006 International Piping Plover Census
This report presents the results of the 2006 International Census of Piping Plovers (Charadrius melodus). Two sets of tabular data are reported: one for distribution and abundance of wintering Piping Plovers, the other for distribution and abundance of breeding Piping Plovers. The winter census resulted in the observation of 3,884 Piping Plovers at 546 sites. The breeding census resulted in the ob

Molecular Population Genetic Structure in the Piping Plover
The Piping Plover (Charadrius melodus) is a migratory shorebird currently listed as Endangered in Canada and the U.S. Great Lakes, and threatened throughout the remainder of its U.S. breeding and winter range. In this study, we undertook the first comprehensive molecular genetic-based investigation of Piping Plovers. Our primary goals were to (1) address higher level subspecific taxonomic issues,

Fire rehabilitation effectiveness: a chronosequence approach for the Great Basin
Federal land management agencies have invested heavily in seeding vegetation for
emergency stabilization and rehabilitation (ES&R) of non-forested lands. ES&R projects are
implemented to reduce post-fire dominance of non-native annual grasses, minimize probability
of recurrent fire, quickly recover lost habitat for sensitive species, and ultimately result in plant
communities with desirable ch

Coldwater fish in wadeable streams
Standardizing sampling methods for fish populations across large regions is important for consistent measurement of large-scale effects of climate or geography. In addition, pooling samples creates larger sample sizes and can facilitate data sharing among scientists and land managers. Sampling freshwater fish has largely not been standardized due to the diversity of fish and habitats. USGS aquatic
