Effective mitigation of biodiversity impacts from development requires an understanding of the type and location of biodiversity and its importance in the area of interest around the development. Data on five characteristics of a biodiversity feature are necessary for analysis to inform mitigation planning. Characteristics required will whether the biodiversity feature under assessment is a species or ecosystem as described below:
- Type of biodiversity: species or ecosystem type
- Amount of biodiversity: number of individuals of a species; extent of an ecosystem
- Condition: population structure of a species; ecosystem condition
- Relative location of the biodiversity feature to other biodiversity and landscape features: i.e. connectivity or isolation of a feature
- Temporal data for the biodiversity feature: i.e. series of data over time of the above characteristics
Analyses and outputs based on these data can contribute to different processes and stages of mitigation. Some outputs and applications include:
Mapping biodiversity, such as species populations and extent of ecosystems, is a first stage of analysis for informing mitigation. Outputs include ecosystem maps or species density maps. National protected areas can also be included into related outputs to aid understanding of data. These can inform national conservation actions and be incorporated into a National Biodiversity Strategy and Action Plan.
