The Living Vermont Index database currently holds time-series data for over ### populations of more than ### species of animals and ### plant species, which are gathered from a variety of sources such as journals, online databases and government reports. Using methods developed by Living Planet Index, these species population trends are aggregated to produce indices of the state of biodiversity in Vermont.

The data used in constructing the LVI are time-series of either population size, density (population size per unit area), abundance (number of individuals per sample) or a proxy of abundance (for example, the number of nests recorded may be used instead of a direct population count).
