These raster files showing wetland areas that were functional during Rainwater Basin Wetland Complex Annual Habitat Survey. Annual Habitat Surveys (AHS) identify areas of wetland ponding and function (ponding and potential hydrophyte vegetation) during spring migration. The information is developed by Rainwater Basin Joint Venture to identifying how much habitat the Rainwater Basin Wetland Complex provides to migratory waterfowl on an annual basis. AHS have been completed for 2004 and 2006-2020 where high-resolution aerial photos of the Rainwater Basin Wetland Complex are classified using an image object classification software to determine land cover (hydrophyte water, agriculture water, hydrophytes, agriculture,...

Report,
Urban communities are increasingly shaping the conservation future of the South Atlantic. Major metropolitan areas present both direct threats, such as loss habitat and open space, and indirect threats, such as creating barriers to connectivity. As a result of both these direct and indirect threats, and their scale, metropolitan areas pose a challenge when thinking about corridors and connectivity, and many of the traditional approaches to green infrastructure and conservation are not adequate for urban areas. The Conservation Blueprint (Blueprint) is cross-boundary, cross-organization plan that prioritizes areas for shared conservation action in the South Atlantic. It is designed as a resource for conservation...

This request is in support of the Southeast Natural Resource Leaders Group (SENRLG) Landscape Conservation and Restoration Pilot Project. Phase I of the study was completed with support from UNC Asheville’s National Environmental Modeling and Analysis Center (NEMAC) in June 2011 after working closely with the SENRLG Pilot Project Team in October 2010. The first phase identified federal resources available for supporting ecological, cultural, and sociological resource protection across the Southeast within an adaptive framework for building resilience into the system to address risk climate change impacts on the landscape. To further define the co-benefits of leveraging resources in a synergistic manner on the landscape,...

Description of condition index value scores for estuarine tidal marsh along and within 10 km of the GCPO LCC Gulf Coast subgeography. A series of raster calculations were used in a dichotomous decision-based framework to compile a per-pixel draft condition index value at a 10 m resolution for GCPO estuarine tidal marsh based on the number of configuration and condition endpoints met within each marsh pixel. Pixels not identified as a estuarine marsh but that were identified as having the potential to be marsh were given a score of 1, provided the pixels were not classified as developed. Potential estuarine tidal marsh pixels were derived from a combination of potential estuarine tidal marsh classes in the Landfire...

Assigning a numerical rank to an introduced species is an objective, quantifiable way to describe their relative impacts, and ranks are a valuable prioritization tool for land managers. We applied the Invasiveness Ranking System previously developed by the Alaska Natural Heritage Program to evaluate introduced species known to occur on Aleutian and Bering Sea Islands. This system uses sixteen criteria grouped into four categories to assess invasiveness: distribution, biological characteristics and dispersal ability, ecological impacts, and feasibility of control. Answers to individual questions are assigned a point value and the points are used to calculate subranks for each of the four sections. Each section is...

Scientists strive to develop clear rules for naming and grouping living organisms. But taxonomy, the scientific study of biological classification and evolution, is often highly debated. Members of a species, the fundamental unit of taxonomy and evolution, share a common evolutionary history and a common evolutionary path to the future. Yet, it can be difficult to determine whether the evolutionary history or future of a population is sufficiently distinct to designate it as a unique species.A species is not a fixed entity – the relationship among the members of the same species is only a snapshot of a moment in time. Different populations of the same species can be in different stages in the process of species...
One of the impacts of global climate change for the Hawaiian Islands is a projected increase in sea level of about one meter by the year 2100. This change will impact both biological and cultural resources located along the coastline. Few intact native coastal and lowland plant communities remain in Hawai’i. Many of those that remain contain listed endangered species and provide important habitat for other species such as seabirds, shorebirds, and native invertebrates. Where upslope habitats are available, some coastal plant communities may be able to migrate in response to sea level rise. However, in sites that have no upslope opportunities due to habitat modification by human development, the species and communities...

Traditional Ecological Knowledge, or TEK, is “a cumulative body of knowledge, practice and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationships of living beings (including humans) with one another and with their environments.” With support from the PICCC, scientists at the University of Hawai’i MaÌ„noa have undertaken research that is documenting baseline Traditional Ecological Knowledge for Ka’upulehu, in the north Kona region of Kekaha on Hawai‘i Island. This focused on biological and cultural resources most valued by the community, the challenges they face, and potential coping mechanisms. Through a series of workshops, investigators partnered...

Human effects on the global climate system, principally through changing the atmospheric concentrations of carbon dioxide and other greenhouse gases, are expected to lead to significant warming and other associated changes in the climate worldwide. Human-induced climate changes are likely already observable in quantities such as the global mean temperature, and over the next century can be expected to include significant effects on the local environment in Hawaii and other Pacific Islands. The currently available climate change projections from global coupled atmosphere/ocean models, as summarized for example in the recent IPCC assessment reports, have very limited direct application to Hawaii or other Pacific islands,...

These CLIM-MET stations are meteorological/geological stations that is designed to function in remote areas for long periods of time without human intervention. These stations measure meteorological and wind-erosion parameters under varying climatic and land-use conditions to detect and describe ongoing landscape changes. These data represent multiple years of local detailed landscape and environmental change observations. These data were collected in and close to Canyonlands National Park, Utah from 1 August 2016 to 31 December 2022. These data were collected by U.S. Geological Survey researchers utilizing site visits and automated data collection data loggers. These data can be used to inform studies of local...

The file contains ocular percent cover estimates for eight plant functional types occurring in lake-margin wetland plant communities in the Yukon River floodplain within the Yukon Flats National Wildlife Refuge. Observations were collected along up to four 100-meter linear transects oriented perpendicular to the lakeshore. Eight cover classes were used, and the median % cover for each cover class is shown in the dataset. Separate percent cover observations were recorded for each of eight distinct plant community encountered along each transect. Community types were associated with one of three aggregate community types (Grass/Sedge, Shrub, and Forest) for analyses. The dataset also includes a column indicating whether...
This dataset includes soil properties and microbial data from lake margin soils throughout the Yukon Flats National Wildlife Refuge. Data include multiple lakes that are defined as either stable or drying. Lake margin vegetation communities include graminoid, shrub, and forest. Sols are separated into organic and mineral layers. Microbial data includes different phospholipid fatty acids and soil enzyme activity data for multiple enzymes involved in C,N, and P cycling. Data also includes information on respiration rate constants (k) and labile substrate pool (Ao) from soil incubations. This is a child item of the USGS Data Release: https://doi.org/10.5066/P9QF8RR5
These operational land imager (OLI) value added data sets, maps, and associated ancillary data were compiled as part of an ongoing research aimed at quantifying the riparian vegetation greenness and water use in the lower Colorado River Delta in Mexico. In order to create trend and anomaly maps that characterize these ecosystems Vegetation Index (NDVI) time series imagery from Landsat OLI were acquired and processed over time and space along seven predefined reaches that capture different natural states and management conditions. We used Landsat OLI 30m data as an improvement upon past studies that were based on coarser remote sensing data from the NASA MODIS sensor (250 m). The OLI 30m images provide better characterization...
These data were compiled for evaluating river-reach level plant water use, or evapotranspiration (ET), and vegetation greenness, or Normalized Difference Vegetation Index (NDVI), in the riparian corridor of the Colorado River delta as specified under Minute 319 of the 1944 Water Treaty. The seven reach areas from the Northerly International Boundary (NIB) to the end of the delta at the Sea of Cortez were defined for research activities. Also, these seven reaches are being monitored under Minute 323 of the 1944 Water Treaty. Additionally, these data were compiled for evaluating restoration-level evapotranspiration and vegetation greenness data in Reach 2 and Reach 4, as specified under Minute 323 of the 1944 Water...
The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across the western U.S. using Landsat imagery from 1985-2020. The RCMAP product suite consists of eight fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub and rule-based error maps including the temporal trends of each component. Several enhancements were made to the RCMAP process relative to prior generations. We used an updated version of the 2016 base training data, with a more aggressive forest mask and reduced shrub and sagebrush cover bias in pinyon-juniper woodlands. We pooled training data in areas...
These NetCDF data were compiled to investigate how rangelands in the western U.S. are limited by access to water. As a result, these ecosystems may be especially vulnerable to changes in water availability and drought as a result of climate change. This project utilized an ecosystem water balance model to quantify spatial and temporal patterns of rangeland ecological drought conditions under historical and future climate conditions. Water balance results were used to estimate several metrics that describe the seasonal timing and amount of moisture available for plant utilization in western rangelands. These data represent different aspects of water availability and drought. They are based on 1/16-degree gridded...
