It is one of several grand challenge environmental problems being addressed by NASA's Science Mission Directorate through a national application partnership with the US Geological Survey. NASA and USGS are working together to develop a National Invasive Species Forecasting System (ISFS) for the management and control of invasive species on Department of Interior and adjacent lands. The system provides a framework for using USGS's early detection and monitoring protocols and predictive models to process MODIS, ETM+, ASTER and commercial remote sensing data, to create on-demand, regional-scale assessments of invasive species likely habitats.Recent work on the Invasive Species Forecasting System (ISFS) project has shown the importance of remotely-sensed time-series data in geostatistical models for mapping the distribution of Tamarisk and other invasive plant species. This video shows the habitat suitability for a Tamarisk invasion in the continental United States.  Red indicates areas that are highly suitable and yellow indicates areas which are less suitable.    Texas, New Mexico, and Nevada are the most highly suitable states.   Utah and Arizona have the next greatest risk.  California, Arizona, Montana, Colorado, Oregon, Ohio, Wyoming, and Florida also have a significant risk. || ",

These photos show the seasonal change of one daunting invasive species, the Tamarisk tree, at the Grand Staircase Escalante National Monument in Utah.  It's important to note the slight differences in the Tamarisk growing season when compared to some of the plant life in the foreground and the trees in the background.  These slight seasonal differences allow the science team to distinguish Tamarisk from other vegetation through satellite sensors.  In these photos, the Tamarisk is the pink flowering foliage to the center right of the images. || ",

It can also be used to create on-demand, regional-scale assessments of invasive species patterns and vulnerable habitats. Tamarisk (Salt Ceder) is an invasive plant that typically grows near water and crowds out native species. Tamarisk reflective properties differ from those of its neighboring vegetation throughout the annual life cycle. These different reflective properties can be seen by the naked eye (as in the accompanying seasonal photographs), and can also be seen by satellite sensors. Current Tamarisk infestations and suitable habitats for future growth can be derived from various data sets, including EVI, NDVI, and land cover classifications. || ",

Tamarisk is one of our most harmful invasive species because the plant's long roots tap into underground aquifers. Its groundwater-absorbing qualities may be adding to the severity of the drought in the western U.S.NASA and the USGS are working together to develop a National Invasive Species Forecasting System (ISFS) for the management and control of invasive species. The ISFS combines NASA Earth observations and models with field data to enhance USGS capabilities to map, monitor and predict the spread of significant invasive plant species.Tamarisk's extensive root system can reach up to 50 feet laterally and 100 feet in depth to access the water supply. As this invasive plant draws up large amounts of water, it can lower the water table. Native plants with shallower root systems have to compete for an already-dwindling water supply. One large Tamarisk plant can absorb up to 200 gallons of water per day - that's twice the amount the average person uses in the same timeframe. || ",

This adds to the fuel load, compounding an already high fire danger in the drought-stricken West. When fires ravage an area, Tamarisk ignites quickly, leading to a more severe burn. To make matters worse, this invasive plant tends to come back more quickly than native plants in these burned areas. || ",
