| Abstract: | Valuation of the gains from protection of biodiversity is difficult because the services
that provide the benefits do not normally pass through markets where prices can form.
But the services sometimes pass through markets where consumers or producers
behave in a market-oriented manner, and so the values implicit in this behaviour can
be identified and derived. Estimates of the benefits of biodiversity protection are
derived from the costs of protecting native plant communities from a major weed in
Australia, by following this approach. In 1999, invasion of coastal areas of New
South Wales by bitou bush (Chrysanthemoides monilifera subsp. rotundata (DC.) T.
Norl.) was listed as a key process threatening native plants under the NSW
Threatened Species Conservation Act 1995. In accordance with the Act, the
Department of Environment and Climate Change prepared a Threat Abatement Plan
(TAP) to reduce the impacts of bitou bush on biodiversity at each threatened site. The
costs of protecting sites vary closely with the number of priority native species and
communities at each site. Following standard economic assumptions about market
transactions, these costs are interpreted to provide values the benefits of protecting
extra species, communities, and sites.
Key words: Bitou bush, Chrysanthemoides monilifera, threat abatement plan, valuation of biodiversity, benefit-cost analysis, weed control, defensive-expenditure
