Rj. Hobbs et Mh. O'Connor, Designing mimics from incomplete data sets: salmon gum woodland and heathland ecosystems in South West Australia, AGROFOR SYS, 45(1-3), 1999, pp. 365-392
In this article we assess the potential for developing mimics in situations
where detailed data on the ecophysiology and ecosystem function of the nat
ive ecosystem are not available. We examine two ecosystems in south western
Australia, and draw together available information on these. We discuss wo
odlands dominated by Eucalyptus salmonophloia, which formerly covered much
of the valley bottom land in the Western Australian wheatbelt, and kwongan
or heath which occurs on sandplain soils at the top of the landscape. From
both of these we derive possible mimics which utilise aspects of the native
vegetation which we hypothesise contributed to ecosystem function and resi
lience, but which still allow the production of a harvestable agricultural
product. We conclude that situations for which we have adequate ecological
knowledge from which to develop sound mimics are likely to be rare. We henc
e have to be prepared to make best-bet estimates and use these to develop e
xperimental mimic systems.
