Disjunct populations are those that have become physically separated, resulting in minimal or no gene flow between them. This separation could be caused by a break in a formerly continuous distribution or by long-distance dispersal (jump dispersal) over a barrier. Often, a disjunction takes the form of a larger parent or core population and a smaller outlier, or outliers, but in some instances the disjunct populations are of about the same size.
This database is a digital polygon coverage of Tasmania (captured at 1:500 000 scale) detailing places where concentrations of disjunct flora populations occur. Disjunct flora polygons are given a unique code, the relevant National Estate values and criteria, and cleared land status.
All sites in this coverage are classified according to National Estate criterion A1: Importance in the evolution of Australian flora, fauna, landscapes or climate.
