<code>getAreaTrend</code> is used to calculate changes in area over time. Output
is a list can be used to easily visualise trends for one ecosystem at a time.

A toolbox created by members of the International Union for
Conservation of Nature (IUCN) Red List of Ecosystems Committee for
Scientific Standards. Primarily, it is a set of tools suitable for
