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...

El estado de Chihuahua es el más extenso de la República Mexicana, representa el 12.6% del territorio del país (INEGI, 2001) y posee una amplia gama de recursos naturales de los que se desprenden diversas actividades económicas (INEGI, 2003), por lo anterior resulta indispensable la disponibilidad de información eficiente de los recursos naturales que permita el manejo adecuado de los mismos. La ley forestal de nuestro país, señala que la evaluación de los recursos naturales debe integrar “información estadística y cartográfica”, que permita conocer la dinámica del cambio de vegetación forestal, para poder evaluar las tasas de deforestación y sus principales causas (CONAFOR, 2010). Actualmente la cartografía...

Executive Summary: Fisheries data compilation efforts for this project fell within two large watersheds in Arizona; the Verde River watershed (Desert LCC) and the Little Colorado River watershed (Southern Rockies LCC). We divided the project into two phases; 1) data compilation for the Arizona Game and Fish Fisheries Information Systems (FINS) and 2) a demonstration of FINS through model development and species distribution data. During phase 1, we compiled, cleaned, assigned National Hydrography Dataset (NHD) reach codes to historical data for 113,230 fish records in the Verde River watershed and 43,828 fish records from the Little Colorado River watershed. These records were standardized to meet the Arizona Game...

ANTECEDENTES La Ley de Aguas Nacionales, que entró en vigor el 2 de diciembre de 1992, refuerza el marco institucional para la administración del recurso y consolida a la Comisión Nacional del Agua (CONAGUA) como autoridad federal única en materia de cantidad y calidad del recurso hidráulico nacional, superficial y subterráneo. Dentro de este Marco Institucional es que en 1992 se propone el desarrollo de un Sistema de Información Geográfica del Agua (SIGA) que se constituyera en una herramienta que permitiera integrar, consultar, analizar y desplegar la información georreferenciada para que las unidades de la CONAGUA realizaran con mayor eficiencia las labores de planeación y administración del agua. OBJETIVOS...

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...

The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (for example, urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. NLCD supports a wide variety of Federal, State, local, and nongovernmental applications that seek to assess ecosystem status and health, understand the spatial patterns of biodiversity, predict effects of climate change, and develop land management policy. NLCD products are created by the Multi-Resolution Land Characteristics (MRLC) Consortium, a partnership of...

Abstract: Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the 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 2010–11. U.S. Geological Survey Fort Collins Science Center (FORT) scientists collected an assemblage of biotic, abiotic, and hydrologic data from Topock Marsh during the drawdown and immediately after, thus obtaining valuable information needed by FWS. Building upon that work,...

How well are we protecting common plants and animals? Gap Analysis is the science of answering this question. Developing the data and tools to support that science is the mission of the USGS Gap Analysis Program (GAP). GAP works to ensure that common species – those that are not officially endangered – remain common by identifying those species and plant communities that are not adequately represented in existing conservation lands. Learn more about Gap Analysis >> We work with a wide range of government, academic, non-profit and private partners, providing them with essential data and analyses that they can use to protect the habitats on which the survival of common species depends.
Final Report Abstract: More than half of the world’s population relies upon monsoonal rainfall that supports agriculture. While in many locations climate change is resulting in less moisture from fewer winter storms and more intense summer precipitation events, rural working landscapes (agricultural managed systems) are struggling to recover from increasingly extreme droughts and floods. The Cañada Alamosa watershed, a 420,000 acre in southwestern New Mexico (see figure 1), faces contemporary resource challenges common to the Southwest; overgrazing and fire suppression have led to a loss of deep soils and vegetative cover. This area’s traditional cultural practices of managed stormwater flooding of the historic...

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...
