Improving Detection of Land Use Change in Habitat Conservation Plan Areas Using NASA Earth Observations and a Landscape Anomaly Detection Tool

The US Fish and Wildlife Service (USFWS) monitors and approves the creation of Habitat Conservation Plan (HCP) areas under the Endangered Species Act (ESA). Habitat Conservation Plans allow economic development in areas that have threatened and endangered species with the agreement that the developer provides...

Improving Flood Extent Mapping Using the Coastal Storm Modeling System (CoSMoS) Tool with NASA Earth Observations and UAVSAR within Southern California

The Southern California coast, from Point Conception to the Tijuana River wetland, has become more sensitive to flooding as king tides have increased in magnitude. These king tides are thought to be intensifying due to numerous environmental factors such as storm surges, strong winds, and...

Improving Water Quality Monitoring and Management in the San Francisco Bay-Delta Utilizing NASA Earth Observations in Association with the Delta Smelt

Water quality plays a critical role in California's freshwater supply and environmental health in the San Francisco Bay-Delta. While there are measures in place to protect human and environmental health from poor water quality conditions, implementation of these measures is frequently reliant on physical water...

This is a 2018 Landsat 8 OLI image of Minnesota processed to show Modified Normalized Difference Water Index (MNDWI) and Normalized Difference Vegetation Index (NDVI) values displayed with pink and green color ramps, respectively. Dark pink shades indicate areas very inundated with water; lighter pink shades are less inundated. Dark green shades are healthy vegetation and lighter shades are less healthy. Focusing on areas that contain wetlands is important for stakeholders to maintain inventory accuracy.

Wetlands are a critical feature of our landscape for the ecological services they provide, including protecting water quality, providing habitat to rare species, mitigating erosion, and providing opportunities for recreation. Despite this, wetlands are facing increasing threats from a variety...

Incorporating NASA Earth Observations into an Assessment Tool to Identify Correlations Between Factors Associated with Bee Health

Honey bees (Apis mellifera) are a vital component to global agriculture, however, over recent decades their populations have been declining. Honey bees provide pollination services to more than 90% of the leading 107 global crop types, and without them it is estimated that...

NDVI-processed imagery using data from Suomi-NPP VIIRS on May 1st, 2019 with an overtop of hillshade with vertical exaggeration of 10x. The Uinta National Forest and part of the Manti-La Sal National Forest, located south of the Great Salt Lake, are displayed. Lighter shades of green and blue indicate poor health of vegetation or no vegetation. Shades of brown indicate mildly health vegetation. Shades of dark blue and dark green indicate good to strong health of vegetation. Focusing on areas with bright hues of green as well as terrain, emergency response teams will be aware of potential future fire ignition sites in this area and predict resource allocation.  Keywords: NDVI, eastern Great Basin, VIIRS

The eastern Great Basin (EGB) covers approximately 411,000 km2 within the states of Arizona, Colorado, Idaho, Utah, and Wyoming. Since the 1950s, wildfires have increased in both frequency and size within the EGB and neighboring states. Partners at the Bureau...

Integrating NASA Earth Observations into the Google Earth Engine Platform to Enhance Drought Monitoring in Chile

Chile is characterized by extreme climate variability ranging from the arid Atacama Desert, one of the driest places on earth, to the extremely wet Lake District that averages 2,535 mm of annual rainfall. In recent years, Chile has experienced abnormal climate conditions as record...

This image displays a portion of Eastern Washington State, on the leeward side of the Cascade Mountains. Lightning point data, derived from the ISS Lightning Image Sensor for the year 2018 is overlaid upon 2018 Landsat 8-OLI imagery processed for a Normalized Difference Moisture Index, for the May-October fire season. Sparks symbolize the point coordinates of lightning strikes. The red-orange color shows dry vegetation, while the forest green represents vegetation with a higher moisture content.  Keywords: Amelia Zaino, Ani Matevosian, Amy Kennedy, Evan Bradish, lightning, wildfires, Eastern Washington, vegetation moisture.

According to the Washington Department of Natural Resources, roughly 36% of large fires in the state since 2010 were caused by lightning. General trends also show a greater increase in the number of lightning-ignited fires over the last three decades...

Land use classification imagery using 2020 Landsat 8 OLI data, blended with a false color band combination (6,5,4), with the highway system overlayed in dark blue. Pictured is the Madre de Dios region of Peru, centered around the La Pampa illegal mining site. The light green indicates areas of gold mining, areas in pink represent wetlands, and areas in yellow represent forest cover. Tracking land use change allows agencies to understand where deforestation is occurring.  Keywords: Nelson Huffaker, Oliver Nguyen, Elizabeth Stapleton, Ariel Calle, Nataly Chacon

In the Madre de Dios region of the Peruvian Amazon, forests are being cleared for mining, timber harvesting, road construction, and hydroelectric dam development. These rapid land use changes are increasing human presence in previously sparsely-populated areas, disrupting ecosystems and increasing the...
