Eco Services Of The Brisbane Region


NATURE PROVIDES BILLIONS A YEAR
IN ECOSERVICES TO THE
BRISBANE REGION



This preliminary estimate of the value of ecoservices in the Brisbane Region was prepared by BREC in 1997. We used data from the first State of the Brisbane River Report and a paper in Nature to derive the estimates. The authors of the Nature article note that their values of ecoservices are significant underestimates. The importance of forests in Australian ecosystems to nutrient and water cycling will perhaps increase their estimated value by an order of magnitude. Those with accounting talent should, for fun, compute the Nett Present Value(NPV) of these natural assests.
