established in proximity of biodiverse forests. Hence, biodiverse
planting in south-west Western Australia, south-east South
Australia and south-east Queensland are of higher combined biodiversity
and carbon sequestration value. The present condition
of this native vegetation and the area in proximity will be a key
determinant in the type of biodiverse community that can be established
as detailed by Hobbs et al. (2009). The extent of biotic and
environmental site modification will determine if communities
resembling ‘historical’ native forest can be re-established. Excessive
physico-chemical alteration due to secondary salinisation can render
the soil and the local hydrology fundamentally altered thereby
establishing an alternative ecosystem may be the only possible
alternative (Hobbs et al., 2009).
Along with the current wide range of market opportunities for
farm forestry there is a potential for some emerging markets to provide
very large-scale opportunities in the future including carbon
sequestration (Fig. 4; URS, 2008). We propose that the potential
scale of opportunity (relative size of the circle) estimated for carbon
sequestration will shift when biodiversity considerations are
included in carbon sequestration schemes (Fig. 4).
Based on the potential for incorporating sustainable biodiverse
planting for increased carbon sequestration outcomes, three
options in the plantation continuum (Fig. 1) integrated into farm
forestry practice are explored in further detail.
