12.3 Undertake a threat assessment for each populationA threat / risk assessment for each population (including habitat health assessment)will be conducted during the population monitoring referred to in Section 12.2 of thisplan.The presence and significance of threats will be assessed, recorded and conservationactions recommended for each population. Threats considered will include thefollowing (but not be limited to):• introduced plants and animals;• competing land use;• pollution;• inappropriate fire regimes; and• salinity / waterlogging.Action:Identify/confirm threats to each populationCost: Incorporated into sections 12.2 and 12.312.4 Address threats to specific populationsSpecific conservation actions are expected to be developed from the plannedassessment of existing populations (conservation actions 12.2 and 12.3).Conservation actions may include fencing to exclude stock and/or rabbits, rabbitcontrol, weed control, revegetation (to provide habitat and connectivity betweenhabitats/populations), fire management and management of competing resource use.Where it is necessary to protect a population from physical disturbance, areas can bedemarcated using Environmental Sensitive Area (ESA) markers similar to thosemarkers used to demarcate Declared Rare Flora (DRF) populations.The costs described below are nominal and relate to minor work associated with thedemarcating populations and controlling grazing / weeds. Addressing threats ofsalinity & altered hydrological processes may require action of a larger scale withgreater costs.Action:Undertake population specific conservation actions19
