This study shows the latest developments of the Normalized Difference Vegetation Index (NDVI) in ecology. This data has been used to show the distributions and abundance of herbivores and non-herbivores. Since about 1981 the importance of different temporal and spatial lags on population performance can be assessed by the understanding the population dynamics.  This was previously thought to most useful in temperate environments.  Models can be used to reconstruct old patterns in vegetation in the effects of future environmental change on biodiversity. Since then, the NDVI has been an essential tool for past and future population and biodiversity consequences of change in climate, vegetation phenology and primary productivity.

  1. How does GIS play a role in helping the biodiversity? Are there geographic graphs that show this data?

  2. Is there an example of where this technology has been used? How about a map of a certain area and how it compares to another type of map of that same area?
