This dataset contains shapefiles and associated metadata for Kīlauea volcano's Pu‘u ‘Ō‘ō episode 61g lava flow from May 24, 2016 through May 31, 2017. Episode 61g began with a breakout from the east flank of Pu‘u ‘Ō‘ō on May 24, 2016. Lava reached the Pacific Ocean at Kamokuna on July 26, 2017, and began building a lava delta that extended seaward from the original coastline. This lava delta collapsed into the ocean on December 31, 2016, as reflected in the data for January 12, 2017 and thereafter. The episode 61g lava flow continues as of May 31, 2017, the date of the last mapping to contribute to this dataset. One mapping date is included for each calendar month - usually late in the month - from May 2016 through...

A Vision for the Chihuahuan Desert The Chihuahuan Desert, shared by two nations, is one of the most biologically rich desert ecoregions in the world, alive with large mammals, birds, reptiles and an unmatched diversity of cactus species. The desert’s rivers, streams and springs are considered to be of global significance, home to fish species found nowhere else on earth. Our vision is a Chihuahuan Desert where governments, local communities, non-governmental organizations, academic institutions, landowners, and other stakeholders are working together to ensure that the richness and diversity of wildlife, habitats, natural communities, and ecological processes of the Chihuahuan Desert are conserved and, where necessary,...

The purpose of the plowprint is to track annual grassland conversion to cropland across the Mississippi River Basin and Great Plains region, and to provide a way to measure the loss of this important habitat type, against which annual changes can be compared. This report tracks changes at the sub-regional scale, as well as in the context of the broader geography, and highlights key elements of change each year. The focus of this report is on changes in grassland conversion from 2014-2015, based on data from the USDA National Agricultural Statistics Service Cropland Data Layer and the Agriculture and Agri-Food Canada Annual Crop Inventory. For this analysis, cropland is defined as any annually planted agricultural...

La regionalización implica la división de un territorio en áreas menores con características comunes y representa una herramienta metodológica básica en la planeación ambiental, pues permite el conocimiento de los recursos para su manejo adecuado. La importancia de regionalizaciones de tipo ambiental estriba en que se consideran análisis basados en ecosistemas, cuyo objetivo principal es incluir toda la heterogeneidad ecológica que prevalece dentro de un determinado espacio geográfico para, así, proteger hábitats y áreas con funciones ecológicas vitales para la biodiversidad, las cuales no hubiesen sido consideradas con otro tipo de análisis. En México han habido diferentes experiencias al respecto, dentro de las...

Topock Marsh is a large wetland adjacent to the Colorado River and main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010-2011. Co-applicants Daniels and Haegele of FORT monitored Topock Marsh during the drawdown and immediately after, thus obtained information on immediate effects. However, stress from the drawdown may have a delayed effect on aquatic resources; additionally, significant changes to the infrastructure...

Sky Island grasslands of central and southern Arizona, southern New Mexico and northern Mexico form the “grassland seas” that surround small forested mountain ranges in the borderlands. Their unique biogeographical setting and the ecological gradients associated with “Sky Island mountains” add tremendous floral and faunal diversity to these grasslands and the region as a whole. Sky Island grasslands have undergone dramatic vegetation changes over the last 130 years including encroachment by shrubs, loss of perennial grass cover and spread of non-native species. Changes in grassland composition and structure have not occurred uniformly across the region and they are dynamic and ongoing. In 2009, The National Fish...

The borderlands of the Chihuahuan Desert, in the Big Bend-Río Bravo (BBRB; the Rio Grande is known as the Río Bravo in Mexico) region, have one of the highest levels of diversity and endemic species among the world’s arid and semiarid ecosystems. This large binational area, comprised by a total of eleven protected areas in Texas, Coahuila, and Chihuahua, offers a unique opportunity for conservation because of its isolation from human settlements and the unfragmented nature of its landscape. Connectivity of habitats in these borderlands is essential to maintain and restore biodiversity, particularly in the face of a changing climate. Private land conservation efforts underway in both countries add an important dimension...

These map products of the North American Land Change Monitoring System (NALCMS) are a collaborative initiative between Canada, Mexico, and the United States to monitor land cover - the observed physical cover on the surface of the Earth - and its change over time. These maps represents land cover in 2005, 2010, and land cover change from 2005-2010 based on Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery monthly composites at 250 m spatial resolution. Nineteen land cover classes were defined using the Land Cover Classification System (LCCS) standard developed by the Food and Agriculture Organization (FAO) of United Nations. The NALCMS was developed to depict information about land cover and...

The Apache Highlands ecoregion incorporates the entire Madrean Archipelago/Sky Island region. We analyzed the current distribution of 223 target species and 26 terrestrial ecological systems there, and compared them with constraints on ecosystem integrity (e.g., road density) to determine the most efficient set of areas needed to maintain current biodiversity. The resulting portfolio of 90 areas includes 12.5 million acres (5 million ha) that should be priorities for protection. Conservation strategies include protection and restoration of grasslands, restoration or maintenance of natural fire regimes, and learning more of probable effects of climate change.

In 2006, the Century Commission for a Sustainable Florida called for an identification of those lands and waters in the state that are critical to the conservation of Florida's natural resources. In response, the Florida Natural Areas Inventory, University of Florida Center for Landscape Conservation Planning, and Florida Fish & Wildlife Conservation Commission collaborated to produce CLIP - the Critical Lands and Waters Identification Project. CLIP is now being used to inform planning decisions by the Peninsular Florida Landscape Conservation Cooperative, coordinated by the U.S. Fish and Wildlife Service.

The rapidly increasing demands being placed on our deserts points to the urgent need for a connectivity assessment that spans multiple jurisdictional boundaries and promotes the partnerships needed to implement a regional conservation strategy for this diverse and striking landscape. The vast scale of renewable energy developments proposed in the California deserts are likely to impact habitat connectivity, alter essential ecosystem functions, and eliminate opportunities for species to shift their ranges in response to climate change. The potential impacts of energy development on our existing public lands, specifically to wildlife and their ability to move across the landscape, are enormous. The primary goal of...

The national dataset was clipped to the WLCI envelope by USGS staff. No other processing was performed on the dataset. This map layer is commonly called Bailey's ecoregions and shows ecosystems of regional extent in the United States, Puerto Rico, and the U.S. Virgin Islands. Four levels of detail are included to show a hierarchy of ecosystems. The largest ecosystems are domains, which are groups of related climates and which are differentiated based on precipitation and temperature. Divisions represent the climates within domains and are differentiated based on precipitation levels and patterns as well as temperature. Divisions are subdivided into provinces, which are differentiated based on vegetation or other...

Vegetation and land-cover changes are not always directional but follow complex trajectories over space and time, driven by changing anthropogenic and abiotic conditions. We present a multi-observational approach to land-change analysis that addresses the complex geographic and temporal variability of vegetation changes related to climate and land use. Using land-ownership data as a proxy for land-use practices, multitemporal land-cover maps, and repeat photography dating to the late 19th century, we examine changing spatial and temporal distributions of two vegetation types with high conservation value in the southwestern United States: grasslands and riparian vegetation. In contrast to many reported vegetation...

Welcome to the Wind and Wildlife Landscape Assessment Tool (LAT), a collaboration organized by the American Wind Wildlife Institute (AWWI) and The Nature Conservancy (TNC). The LAT is designed as a landscape-level planning tool to identify sensitive wildlife habitat and areas that are likely to have low wildlife risk where wind energy development could be prioritized. Although the siting of individual wind energy projects will require on-the-ground surveys to verify data shown here, our hope is that this tool will provide stakeholders with information that facilitates the siting of wind energy in areas with minimal impacts to wildlife, as well as the development of conservation plans, monitoring plans and mitigation...
