APPENDIX 4 - Some examples of detailed objectives (using quantifiable indicators)

ATTRIBUTE DETAIL

EXAMPLES

Controlling threats

Nil incidence of undesirable livestock incursions

Climate-readiness of xx species considered and appropriate propagules arranged

Invasive plant threats under management in surrounding landscape

Fox and cat populations reduced to xxha and xxha respectively in surrounding landscape

Overharvesting regulated in surrounding marine area

Anti-fouling pollutants prohibited in surrounding waters

Physical conditions

pH of substrate is between e.g. xx.xx and xx.xx(Raupach test)

A minimum of XX mm of top soil (A horizon) and yy mm of subsoil (B horizon) is installed at establishment.

Topsoil and subsoil are returned within 2 months of initial clearing

Soil compaction reduced to <xx psi across site

Nil sediment deposition in stream

Site topography and hydrological flow lines reinstated

Salinity level of substrate < EC Units

Turbidity level = xxx

Rocky outcrops cover xx% of site and remain without vegetation cover

Species composition

Herbaceous exotics reduced to <xx% cover and represented by only benign species

>xx% canopy cover of indigenous trees and exotic trees reduced to rare seedlings

mesic shrubs reduced to <xx% cover and diversity of heathy shrubs maintained

Kangaroo Grass cover between ~xx-xx% FPC and diversity of forbs and grasses maintained.

Crown of Thorns Starfish reduced to >xx% cover and coral mortality < xx%

Carp reduced to <xx% of fish population and xx% of indigenous fish species of reference present

Community structure

Characteristic diversity of indigenous plant species from each stratum established

Mosaic of vegetation patches reinstated

All ant functional groups present

All frog species present

Size of area sufficient to support populations of species ‘x’

Species ‘y’ present at a density of x stems per ha

Ecosystem function

All plant species regenerating after natural disturbance event

A diversity of genera of saprophytic insects found in all fallen timber

‘xx’ number of tree hollows per hectare

Owl pair breeding in area and feeding on site

Litter decomposition rate = xx

Filtration rate = x% of tide residence time

Appropriate fire regime reinstated for the target ecosystem

Carbon sequestered at a rate of xx tonnes per year

Positive change in the microbial functionality parameter ‘xx’

External exchanges

Ground dwelling faunal species can readily disperse into and out of site

Site is connected to surrounding floodplain and river to enable periodic flooding

Fish passage reinstated

Tidal flushing reinstated

Pollinators can readily connect with site


Note: The ‘indicator’ is the measure used – while the ‘objective’ is the quantification adopted for the particular project.
