This project is to be spread over a minimum of a four year period for the control/eradication of Dalmation Toad Flax and Dyer’s Woad, from private and public lands around and on Raymond Mountain in the Sublette Mountain Range. The Toad Flax and Dyer’s Woad are decreasing the forage available to wildlife in this area as these two noxious weed species continue to expand their populations. For the past five or six years, BLM and Lincoln County Weed and Pest have been spraying and/or releasing biologicals against these weeds, and it is now time to also attack these weeds on the low lands, which are privately owned, eliminating this possible seed source. The benefits to controlling the Dalmation Toadflax and Dyer’s Woad...

There is a critical need to increase the level of control to minimize the economic and ecological impacts that invasive species cause. BLM has a commitment to Sweetwater County and private adjacent land owners for controlling weeds. Control of noxious weeds is a priority within the local county and the Bureau. Native wildlife species, including elk, mule deer, greater sage-grouse, mountain plovers, raptors, Colorado River cutthroat trout and many juniper obligates, are dependent on native vegetation for successful breeding, nesting, and food. Protection of their habitats is of primary importance. One community at risk is riparian habitat where invasive weeds are displacing native species. Weeds affect streams by...

These data represent coastal corridors exposed by lake levels reduced from mean 2009 water surface elevations. These elevations were established by values published by the United States Army Corps of Engineers (USACE), and based on a network of multiple gages within each lake. The corridors were derived from two data sources: 5-m resolution lidar-based topo-bathymetry produced by the USACE Joint Airborne Lidar-Based Technical Center of eXpertise (JALBTCX) and the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center, and bathymetric contour lines produced by the NOAA Great Lakes Environmental Research Laboratory (GLERL). The JALBTCX lidar-based topo-bathymetry were used to produce representations...

These data sets consist of data collected during 2005-2007, 2010, and 2015 at Neal Smith NWR (IA) and Fergus Falls, Litchfield, and Morris Wetland Management Districts (MN) that were used in the analysis in support of the article titled "Integrity of tallgrass prairie reconstructions ten years after planting: native plant persistence and exotic weed resistance," which has been submitted to the journal Restoration Ecology. The primary goal of this study was to understand what influence early reconstruction practices have on long-term outcomes. Twelve replicates of three planting methods (dormant-season broadcast, growing-season broadcast, and growing-season drill) and three seed mix richness levels (10, 20 or 34...

Understanding the terrestrial carbon budget, in particular the strength of the terrestrial carbon sink, is important in the context of global climate change. Considerable attention has been given to woody encroachment in the western US and the role it might play as a carbon sink; however, in many parts of the western US the reverse process is also occurring. The conversion of woody shrublands to annual grasslands involves the invasion of non-native cheatgrass (Bromus tectorum) which in turn leads to increased frequency and extent of fires. We compared carbon storage in adjacent plots of invasive grassland and native shrubland. We scaled-up the impact of this ecosystem shift using regional maps of the current invasion...

Questions: Exotic plant invasion may be aided by facilitation and broad tolerance of environmental conditions, yet these processes are poorly understood in species-rich ecosystems such as riparian zones. In the southwestern United States (US) two plant species have invaded riparian zones: tamarisk (Tamarix ramosissima, T. chinensis, and their hybrids) and Russian olive (Elaeagnus angustifolia). We addressed the following questions: (1) is Russian olive able to tolerate drier and shadier conditions than cottonwood and tamarisk? (2) Can tamarisk and cottonwood facilitate Russian olive invasion? Location: Arid riparian zones, southwestern US. Methods: We analyzed riparian tree seedling requirements in a controlled...

Project Synopsis: this project would fund the labor for mechanical, biological, and chemical applications in an effort to gain control of Perennial pepperweed, Russian knapweed, whitetop, Marsh sowthistle, and saltcedar. The watershed drains into the North Platte River which currently does not have perennial pepperweed. This area has crucial winter range for deer and elk, and yearlong range for antelope. There are sage grouse wintering areas and brood-rearing habitat, as well as numerous leks, and mountain plover. There are perennial streams with several species of willow. There have been efforts to improve Sage Creek proper, which was listed on the 303d list of impaired streams due to habitat degradation, and...

In drylands of southeastern Utah, USA, the invasive exotic grass Bromus tectorum L. occurs in distinct spatial patterns suggesting soil control of ecosystem susceptibility to invasion. To improve our understanding of these patterns, we examined performance of B. tectorum in relation to additions of water, KCl, MgO, and CaO at seventeen 1600 m2 sites distributed across a calcareous soil gradient in Canyonlands National Park. Water additions resulted in a 57% increase in B. tectorum establishment. Fall establishment was significantly correlated with silt and clay content in wet plots but not in dry plots, suggesting that texture effects on B. tectorum establishment patterns may be greater in wet years than in dry...

Question: How do patterns in colonization and patch expansion of an invasive woody plant (Larrea tridentata, Zygo-phyllaceae) differ between two grassland ecosystems at a biome transition zone? Location: Semi-arid/arid transition zone in central New Mexico. Methods: Frequency of occurrence, height, and surface area of saplings (n = 134) and patches of adult plants (n = 247) of the invasive shrub, L. tridentata, were measured within a mosaic of ecosystems dominated either by the Chihuahuan Desert species, Bouteloua eriopoda (Poaceae), or the shortgrass steppe species, B. gracilis, located within 1 km of the L. tridentata-dominated ecosystem. Distances between L. tridentata patches and patch area were used to estimate...

The strategy for this project will incorporate Fall and Spring treatments of BLM approved herbicide on approximately 100 acres. Following treatments will not exceed 1000 acres per treatment year. The Sublette County Weed and Pest is also providing support for this project through aerial, roadside, and follow-up backpack applications. They are also supplying herbicides for the initial treatment. Habitat classification are mixed cool season grasses, Big Sagebrush communities, winter range for Mule Deer, moose, pygmy rabbit, and brood rearing habitat for sage-grouse. This area is not an active allotment; however, due to treatment timing grazing will not be affected. Livestock management will not be affected but grazing...

The first basin-wide map of large stands of invasive Phragmites australis (common reed) in the coastal zone was created through a collaboration between the U.S. Geological Survey and Michigan Tech Research Institute (Bourgeau-Chavez et al 2013). This data set represents a revised version of that map and was created using multi-temporal PALSAR data and Landsat images from 2016-2017. In addition to Phragmites distribution, the data sets shows several land cover types including urban, agriculture, forest, shrub, emergent wetland, forested wetland, and some based on the dominant plant species (e.g., Schoenoplectus, Typha). The classified map was validated using over 400 field visits.

Bubble curtain systems, also called “bubblers,” are used in navigation locks to prevent the buildup of ice around the gates in the winter. It has been proposed that bubblers could potentially serve an additional purpose as a deterrent to the upstream movement of aquatic invasive species through locks. An interagency study involving the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and the U.S. Geological Survey is aimed at assessing this potential (Asian Carp Regional Coordinating Committee, 2019). As part of this effort, on September 17 and 18, 2019, the U.S. Geological Survey measured water velocities around the bubble curtain system in Peoria Lock on the Illinois River. Peoria Lock has “sill...
