Plate 5. Frame from animation of carbon sequestration for the O’Shannessy catchment in the Central Highlands of

Victoria at starting year (2002). The animation of the total carbon accumulation was calculated within about 20

seconds for a period of 200 years. The advantage of animations will be mainly in visualizing different land-use

scenarios.
