Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

In Hawai‘i and other oceanic islands with few native land mammals, black rats (Rattus rattus) are among the most damaging invasive vertebrate species to native forest bird populations and habitats, due to their arboreal behavior and generalist foraging habitats and habitat use. This is a selected data set used to assess the impacts of rodenticide treatment on black rat (Rattus rattus) abundance within Hawaii Volcanoes National Park (HAVO). The key objective was to identify rat abundance before and after rodenticide treatment, using paired non-treatment and treatment plots at high elevation (1700-1830m) and low elevation (1220-1340 m). This dataset includes the results of a mark recapture study that took place within...

In support of U.S. Geological Survey invasive carp research examining aggregations of invasive carp in the tail water of dams, water velocity measurements were made at cross sections in the Illinois River below Starved Rock Lock and Dam on June 16, 2021. A total of 16 cross sections were surveyed, with two transects per cross section. Water depth and crew safety limited the extent of the survey. The discharge in the Illinois River at Starved Rock Lock and Dam at the time of data collection was approximately 185.7 cubic meters per second. The data were processed in the Velocity Mapping Toolbox (VMT) v.4.09 (Parsons and others, 2013) to obtain a depth-averaged velocity field for each cross section from paired transects...

Invasive species may vary in their seasonal distribution and abundance due to environmental conditions such as precipitation and temperature. Bigheaded carps, which include silver and bighead carp, are one such taxon of invasive species that appear to change habitats seasonally. Seasonal changes in bigheaded carp distribution may occur because of hydrological changes, water temperature changes, and spawning activities. Monitoring this seasonal dispersal and migration is important for management to control the population size and spread of the species. We examined if environmental DNA (eDNA) approaches could detect seasonal changes in the occurrence of DNA in water samples and used these approaches to calculate the...

To determine if invasive annual grasses increased around energy developments after the construction phase, we calculated an invasives index using Landsat TM and ETM+ imagery for a 34-year time period (1985-2018) and assessed trends for 1,755 wind turbines (from the U.S. Wind Turbine Database) installed between 1988 and 2013 in the southern California desert. The index uses the maximum normalized difference vegetation index (NDVI) for early season greenness (January-June), and mean NDVI (July-October) for the later dry season. We estimated the relative cover of invasive annuals each year at turbine locations and control sites and tested for changes before and after each turbine was installed. These data were used...

Observations and subtle shifts of vegetation communities in western Lake Erie have USGS researchers concerned about the potential for Grass Carp to alter these vegetation communities. Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities and establish baseline conditions for assessing future effects. Existing aerial imagery was used with object-based image analysis to detect and map aquatic vegetation in the western basin of Lake Erie.

These heatmaps show a top 3 invasive and problematic plant stressor for riparian areas in the Chihuahuan Desert, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor across the landscape. Symbology represents the percentage of participants with 0% = dark green, 0.0001 % - 24.99% = light green, 25% - 49.99% = yellow, 50% - 74.99% = orange, 75% - 100% = red. All counties and municipalities identified by participants as areas where they work were given a tally for each of the top 3 stressors that participants chose. Counties with a small number of participants were not adjusted for small sample size. These results were...

Amur honeysuckle bush (Lonicera maackii) and Morrow's honeysuckle (Lonicera morrowii) are two of the most aggressively invasive species to become established throughout areas along the Blue River in metropolitan Kansas City, Missouri. These two large, spreading shrubs (locally referred to as bush honeysuckle in the Kansas City metropolitan area) colonize the understory, crowd out native plants, and may be allelopathic, producing a chemical that restricts growth of native species. Removal efforts have been underway for more than a decade by local conservation groups such as Bridging The Gap and Heartland Conservation Alliance, who are concerned with the loss of native species diversity associated with the spread...

Coastal wetlands are major global carbon sinks, however, they are heterogeneous and dynamic ecosystems. To characterize spatial and temporal variability in a New England salt marsh, static chamber measurements of greenhouse gas (GHG) fluxes were compared among major plant-defined zones (high marsh dominated by Distichlis spicata and a zone of invasive Phragmites australis) during 2013 and 2014 growing seasons. Two sediment cores were collected in 2015 from the Phragmites zone to support previously reported core collections from the high marsh sites (Gonneea and others 2018). Collected cores were up to 70 cm in length with dry bulk density ranges from 0.04 to 0.33 grams per cubic centimeter and carbon content 22.4%...

Our proposal addresses Funding Category Ill by evaluating natural resource management practices and adaptation opportunities. More specifically, our project addresses Science Need #6 to improve monitoring and inventory of watersheds and ecosystems (including invasive species). Our proposed study will occur within the Southern Rockies Landscape Conservation Cooperative (LCC) (upper Virgin River, UT) and the Desert LCC (lower Virgin River, AZ and NVL and therefore will be submitting to both cooperatives. Invasive saltcedar (Tamarix spp.) is the third most abundant tree in Southwestern riparian systems (Friedman et al. 2005). Resource managers must often balance the management goals of protecting wildlife species and...

Introduction: Tamarisk (Tamarix spp., also saltcedar) is a non-native tree introduced to the United States during the 19th century as an ornamental species and solution to erosion in the American West (Robinson 1965). Tamarisk can form dense monotypic stands, which have been linked to a decline in richness and diversity of native plants (Engel-Wilson & Ohmart 1978; Lovich et al. 1994) and wildlife (Anderson et al. 1977; Durst et al. 2008) in riparian areas. As a result, natural resource managers have invested millions of dollars to control tamarisk (Shafroth & Briggs 2008). Few studies have conducted community-level analyses to document the impact of one of these methods, the introduction of a native enemy or predator,...

Burmese pythons are an invasive species in the Greater Everglades Ecosystem. Burmese pythons captured in the ecosystem are euthanized, and in an effort to learn about this invasive species, all euthanized pythons are necropsied, during which time samples are collected. We analyzed the stable isotope ratios of carbon and nitrogen in muscle samples from 423 Burmese pythons euthanized and necropsied between 2003-05-01 and 2012-09-02, and after processing and QA/QC, we were left with isotope ratios for 410 samples, which we reported here. We used these data to estimate the size of the isotopic niche of the Burmese python, commonly measured using standard ellipse areas, or SEAs. To put these SEAs in context, we conducted...

The Rio Grande cutthroat trout is New Mexico’s state fish; but habitat loss and non-native trout invasions threaten the persistence of this fish throughout the remaining 12% of its historic range. Stakeholders, including state agencies, federal agencies, Tribal nations, Pueblos, and private groups are particularly concerned about the impact that non-native brown trout have on native cutthroat trout. This project will be the first to demonstrate how non-native brown trout negatively affect Rio Grande cutthroat trout populations. The project has two primary objectives: 1) compare the health and characteristics of native Rio Grande Cutthroat Trout in areas both with and without invasive brown trout in cold and warm...

In May 2014, the GNLCC Steering Committee approved two pilot projects explore approaches to landscape-scale coordination to enhance science-based management across the GNLCC. The two ‘Shared Landscape Outcomes’ pilots were designed to assess and focus on specific pairs of a GNLCC Goal and a priority landscape stressor (as defined in the Strategic Conservation Framework) and focus the approach at the entire GNLCC scale. The two pilot projects focused on (1) the Connectivity goal and Land Use Change stressor (described here) and (2) the Aquatic Integrity goal and Invasives stressor and (see: https://www.fws.gov/science/catalog )Connectivity Pilot:Wildlife species are becoming increasingly isolated in patches of habitat,...

This project will apply the results of an on-going climate change vulnerability assessment to the management of two complex landscapes. The vulnerability assessment project team will work with mangers, land-owners, and conservation practitioners to explore 1) how downscaled climate datasets, modeled vegetation changes, and information on estimated species sensitivities can be used to develop climate change adaptation strategies, and 2) how model results and datasets can be made more useful for informing the management of species and landscapes. To accomplish these two goals, we will prepare datasets and model outputs for two landscapespotentially, the Pioneer Mountains-Craters of the Moon region in Idaho and the...

The Arizona Game and Fish Department (AGFD) recognizes the need for a strong data foundation to inform science-based decisions for fisheries management at a watershed level. In preparation for a shift towards comprehensive watershed-scale planning, AGFD is developing a fisheries data management system with an initial focus on compiling and formatting several hundred thousand fish survey and stocking records. Fish data will be integrated within a Geographic Information System (GIS) by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which will allow for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by...

Russian olive and tamarisk are two invasive species that have established along the Green River. These two species are poor riparian plants and are outcompeting the native vegetation. Native vegetation is well suited to stabilize stream banks and capture sediment, thereby improving water quality. Currently the Wyoming Game and Fish Department has funded the Teton Science School to conduct an assessment from Fontenelle Dam to the southern end of Seedskadee National Wildlife Refuge (NWR), and the City of Green River is treating Russian olive and Tamarisk on their properties. There is a need to complete an assessment from the southern boundary of Seedskadee NWR to Flaming Gorge Reservoir, initiate control measures...
