Using NASA Earth Observations to Quantify Tree Mortality and Burn Severity to Inform Management on Ranches and Open Lands

Both wildfires and conifer-defoliating insect outbreaks have increased in frequency and severity in recent years. Western spruce budworm (Choristoneura freemani), a widespread defoliator in western U.S. forests, has impacted over 6,000 hectares of forest in southern Colorado. The forest managers for southern Colorado’s Tercio and...

Daytime average land surface temperatures calculated from April-September, 2015 – 2020 Landsat 8 TIRS data. The image shows downtown Austin, Texas, the surrounding Hill Country, and Lake Travis. Red and yellow values represent highest temperatures, while blue and white values depict cooler areas, including the Colorado River system that runs through the city. Yellow areas highlight built-up features associated with higher temperatures, suggesting where partners should focus their efforts on mitigating heat hazards for vulnerable communities.  Keywords: Urban Heat, Land Surface Temperature, Landsat8, Alexa Lopez, Will Peters, Margaret McCall, James Sanders

In recent years, Austin, Texas has experienced an increase in population and urban development. Additionally, the City’s climate continues to change and currently faces extreme heat and drought. As temperatures and demand for utilities and resources rise, the number of...

A model-produced feasibility map of aspen regeneration after the Spring Creek wildfire in 2018, (extent shown in red). This was overlaid on an NDVI-composite produced from Landsat 8 OLI Tier 1 surface reflectance (September 2019)(shown in shades of blue) of Trinchera Ranch in Southern Colorado. The model was trained on data from Landsat 8 OLI/TIRS, Sentinel-2 MSI, and SRTM from the Summer of 2017 and 2019 (before and after the fire, respectively). Areas most suitable for aspen regeneration after the disturbance are in yellow.   Keywords: Aspen, Wildfire, NDVI, Random Forest, Spring Creek, La Veta, Colorado, Landsat, Sentinel

Quaking aspen (Populus tremuloides) is an important species for wildlife, watershed health, and ecosystem resilience across its range. Heavy ungulate browsing and factors influenced by a changing climate including seasonal temperature changes and moisture deficit have led to...

Utilizing Landsat to Detect Ephemeral Water Sources in Support of a USGS Feasibility Assessment and Management Strategy of Equids

Since 1971, federal agencies have been tasked with managing burros in federally-designated herd management areas (HMAs). Because these areas are often large and remote, obtaining sufficient data on horse and burro populations and habitat preference can be difficult and expensive. In recent years, the United...

Utilizing Multispectral Satellite Imagery to Monitor and Predict the Displacement of Cladophora along the Milwaukee County Shoreline

Changing lake conditions, such as rising temperatures and phosphorus cycling by invasive Dreissenid mussels, have made washup of the green macroalgae Cladophora glomerata a consistent problem on beaches in Milwaukee County, presenting a threat to both wildlife and the local economy. Groundwork Milwaukee (GWMKE), a...

Utilizing NASA and ESA Earth Observations to Monitor Turbidity Conditions in the San Francisco-Bay Delta

Water quality is a critical element of freshwater supply, particularly in times and areas of drought. Limited water resources can be further strained if water quality concerns are not effectively and efficiently addressed. While there are measures in place to protect human and environmental health...

NDVI-processed imagery using 2019 Landsat 8 OLI data for the city of Louisville, Kentucky. Blue indicates high positive NDVI values, red indicates low negative values, and yellow indicates values close to 0. Areas with NDVI values close to and below 0 tend to have little vegetation which may be high priority areas for greening initiatives.  Keywords: Greenness, NDVI

Greenness and land surface temperature (LST) have been extensively correlated to urban public health. Chronic diseases such as diabetes, asthma, and cardiovascular illnesses have been linked to regions of high LST and areas lacking urban green spaces. One of our...
