Appendix 4: Threat assessment for Zieria granulata sites
The following threat assessment for Z. granulata sites has been undertaken to provide direction to decision makers as to where the recovery effort for the species will be most effectively applied. The assessment is based primarily on the zoning and tenure of sites although adjustments have been made where site specific knowledge, regarding sites that are subject to conservation agreements for example, allows. The assessment is based on data available in December 2003.
For this assessment, threats have been categorised into the following classes developed by Keith et al. (1997):
- Class I threats are processes capable of causing a sudden, substantial and irreversible loss of individuals or habitat. An example is vegetation clearance followed by land-use change.
- Class II threats are processes capable of causing gradual, substantial and possibly irreversible loss of individuals or habitat. Examples include habitat degradation due to overgrazing or weed invasion. These processes may be reversible but mitigation may be technically difficult or expensive to achieve.
High risk
High risk sites are those sites that are considered to be at greatest risk from Class I threats. This category contains all sites that are presently zoned for mineral extraction or residential development. It also includes sites that are located in areas that have been identified as containing state significant mineral resources. Recovery actions at high risk sites should focus on reducing the risk from Class I threats. This can be achieved by increasing the level of legislative protection afforded these sites through mechanisms including the negotiation of conservation agreements and in the preparation of environmental planning instruments. The implementation of on-ground threat abatement works at high risk sites is not recommended until the risk from Class 1 threats is reduced.

Moderate risk
Moderate risk sites are those sites that are considered to be at a low to moderate risk of Class I threats and are primarily at risk from Class II threats. This category contains sites that are zoned rural and which occur outside areas that have been identified as containing state significant mineral resources. It also contains sites that are zoned for environmental protection but are not located within crown reserves, council reserves or national parks.
Recovery actions at these sites should focus on reducing the risk from Class I threats. This can be achieved by increasing the level of legislative protection afforded these sites through mechanisms including the negotiation of conservation agreements and in the preparation of environmental planning instruments. Actions should also aim to raise the awareness of landholders to encourage land-use change and prevent inadvertent damage to the species. On-ground threat abatement works should be implemented where the landholder indicates a desire to assist in the recovery program.

Low risk
Low risk sites are those sites that are considered to be primarily at risk from Class II threats. This category includes sites that are located in national parks, crown reserves, or council reserves. It also includes privately owned lands that are subject to Voluntary Conservation Agreements (VCAs) under the National Parks & Wildlife 1974 or Registered Property Agreements (RPAs) under the Native Vegetation Conservation Act 1997. Recovery actions at these sites should focus on addressing the Class II threats through liaison with landholders and the implementation of on-ground threat abatement works in accordance with plans of management and site management statements.
