About The Author

Dr. Fern is a postdoctoral Research Ecologist at the Northern Prairie Wildlife Research Center.
Her professional experience consists of projects from a wide range of topics such as
ecotoxicology of surfactants in coastal systems, spatial ecology of Nearctic-Neotropical
passerine migration, incorporating complex biotic interactions into species distribution models
in agricultural landscapes, and advancing vegetation indices derived from remotely sensed
imagery to inform rangeland management.

Using NDVI And OSAVI To Monitor Rangeland Health

As the demand for agriculture grows, rangeland managers are charged with the task of managing larger and more complex operations. However, many rangelands (especially in predominantly livestock-agricultural states like Texas) are often too large and inaccessible to assess and monitor the health of vegetation by hand. In recent decades, since satellite imagery has become regularly
