Digital aerial imagery provides baseline data for mapping vegetation types and other land cover features. Vertical photographs (photographs taken with the aerial camera pointed straight down at the ground) collected with proper overlapping within each flight line permit an interpreter to study the photographs three-dimensionally with a stereoscope (Avery 1978) or, as with the Mississippi National River and Recreation Area (MISS) vegetation mapping project, to view stereo models of digital aerial images in three dimensions (3D) using computer workstations. Because ecologic settings are taken into account when mapping vegetation types, the ability to view the aerial images in 3D assists the recognition of those ecologic...

Separate data for floodplain elevation and bathymetry were collected on the Upper Mississippi River System (UMRS) by the US Army Corps of Engineers (USACE), Upper Mississippi River Restoration (UMRR) program. While many information needs can be met by using these data separately, in many cases seamless elevation data across the river and its floodplain are needed. This seamless elevation surface was generated by merging lidar (i.e., floodplain elevation) and bathymetry data. Merging the data required special processing in the areas of transition between the two sources of data.

The U.S. Geological Survey (USGS) is providing an online map of potentiometric-surface altitude contours in the Lloyd and North Shore aquifers on Long Island, New York, April-May 2013. USGS serves this map and geospatial data as a REST Open Map Service (as well as HTTP, JSON, KML, and shapefile), so end-users can use the map and data on mobile and web clients. A companion report, U.S. Geological Survey Scientific Investigations Map 3326 (Como and others, 2015; http://dx.doi.org/10.3133/sim3326) further describes data collection and map preparation and presents 68x22 in. PDF versions, 4 sheets, scale 1:125,000. This polyline shapefile consists of digital contours that represent the potentiometric-surface...

Note: The download link includes Fish Regions, Freshwater Ecoregions, and Freshwater Resilience. Within each freshwater ecoregion, we defined one to four discrete fish regions using a cluster analysis of the USGS 8-digit Hydrologic Units (HUC) based on similarities in their native fish composition. The analysis was based on a previously developed list of native species present within each HUC (NatureServe, 2008). The cluster analysis defined up to four clusters within each freshwater ecoregion using similarity of composition (Linkage method: Flexible beta, Distance measure: Sorensen (Bray-Curtis), Flexible beta value of -0.250). To determine the faunal distinctiveness between clusters, we performed an indicator...

Resilience concerns the ability of a living system to adjust to climate change, to moderate potential damages, to take advantage of opportunities, or to cope with consequences; in short, its capacity to adapt. In this project we aim to identify the most resilient examples of key geophysical settings (e.g. sand plains, granite mountains, limestone valleys, etc.) to provide conservationists with a nuanced picture of the places where conservation is most likely to succeed over centuries. The project had three parts: 1) identifying and mapping the geophysical settings, 2) developing a quantitative estimate of resilience for each setting based on landscape complexity and permeability, and 3) identifying key linkages...

Wildfire is a dominant ridge to reef threat to human and natural communities in the Hawaiian Islands, with impacts to natural and cultural resources and ecoystem services. Fire regimes in Hawaii have shifted from very infrequent wildfire occurrence prior to human arrival to greatly increased frequency, intensity, and size over the past 100+ years, almost all of which is driven by anthropogenic ignitions and wildland fuels associated with invasive species, particularly grasses. Recent fire science has greatly increased understanding of contemporary drivers of fire in Hawaii; however, the social dimensions and historical perspectives from Hawaiian language primary sources have not been integrated into synthetic understanding...

NOTE: Two data download links are provided. The first includes the data described below as a geographic point layer and as a .csv file. The second link is a data package containing: the annual probability of observing one individual, the annual probability of encountering a large flock, and the monthly probability of observing one individual, for the full set of 24 species (in .csv format), and the associated report “Mapping the distribution, abundance and risk assessment of marine birds in the Northwest Atlantic.” To improve display of this data on Data Basin the point data was converted to a raster grid. This map depicts the mean predicted probability of observing at least one individual Black-legged Kittiwake...

This data set represents the Wildlife Habitat Management Area boundaries. The Wyoming Game and Fish Department, under the direction of the Wyoming Game and Fish Commission, administers lands and public easement areas that are home to vast numbers of fish and wildlife. The department maintains approximately 413,000 acres of land under deed, lease or by agreement and continually strives to acquire new access areas. These areas include access to nearly 225 miles of streams, over 21,000 lake surface areas, and more than 148 miles of road right-of-ways. Management of these lands demonstrates our state's commitment to its precious wildlife heritage and those people who seek to enjoy our wildlife and wild lands.Wyoming's...

We developed a screening system to identify introduced plant species that are likely to increase wildfire risk, using the Hawaiian Islands to test the system and illustrate how the system can be applied to inform management decisions. Expert-based fire risk scores derived from field experiences with 49 invasive species in Hawai′i were used to train a machine learning model that predicts expert fire risk scores from among 21 plant traits obtained from literature and databases. The model revealed that just four variables can identify species categorized as higher fire risk by experts with 90% accuracy, while low risk species were identified with 79% accuracy. We then used the predictive model to screen 365 naturalized...
