Priority native vegetation conditions
Revegetation is defined as planting or direct seeding on land with minimal or no native vegetation and provides a form of biosequestration.
Biosequestration is a climate change mitigation activity. It is the capture and storage of the atmospheric greenhouse gas carbon dioxide by biological processes (Parliament of Australia, 2010). Investment in native vegetation establishment and management for biosequestration provides opportunities to improve our environment and can also provide adaptation benefits. If this is not well planned it can also pose risks, for example, fire, water availability and pest management. The challenge is to maximise the benefits and minimise the impacts from any investment in this area.

The CRP combines mitigation and vulnerability priorities to determine climate change priorities (see figure 1). Mitigation priorities are modelled by combining carbon potential and biodiversity values (see map 1, CRP*). Vulnerability mapping is overlaid to provide combined mitigation and vulnerability (adaptation) priorities (see map). The resulting maps provide priority locations for climate change mitigation and adaptation activities (for more detailed examples see the LGA maps 8, 11, 14, 17, 20, CRP*). Maps identifying areas of ‘special interest’ for example, fire management, are accompanied with protocols for communication with relevant authorities. Protocols are designed to ensure that appropriate communication, risks and opportunities are addressed as soon as possible.
Depending on the priorities of the investor and the proposed on-ground action the value of specific attributes can be increased and decreased, which will modify priorities. The maps can also be combined with other ‘special interest’ priority mapping to refine priorities. For example, the native vegetation mapping could be combined with priority mapping from the Trust for Nature State-wide Conservation Plan (Trust for Nature, 2013) or the Habitat 141 Landscape Conservation Plan (Koch, 2015).
The following conditions are mechanisms to maximise the benefits of large scale biosequestration activities and minimise the impacts. A series of maps accompany these mechanisms providing prioritised locations for native vegetation revegetation and management.
