NaturePrint v4.0 Strategic Biodiversity Values 

Alternate title

NATUREPRINT_4_0_SBV 

Resource Type

Dataset  

Purpose

The information provided by SBV is potentially useful for a wide range of decision makers and natural resource managers. Information about the relative value of biodiversity assets can help inform conservation decision-making processes, such as: - native vegetation permitted clearing and offsetting - prioritising areas for protection - raising awareness of the spread of biodiversity values across Victoria.

Statement

Dataset Source: SBV v4 was created by combining and analysing biodiversity information across Victoria using Zonation conservation planning software. The objective of this analysis was to rank all locations across Victoria for their ability to represent threatened (VROT) vertebrate fauna, vascular flora, and the full range of Victoria¿s native vegetation. It is based on efficient and effective spatial coverage of these biodiversity values. Dataset Originality: Primary & Derived 

Description

The biodiversity information used in the SBV v4 analysis included: - species habitat distribution models - models of uncertainty of the likelihood of modelled habitat (and, for fauna, habitat importance models) for VROTS - models of vegetation types in Victoria - a model of native vegetation condition. The analysis first looked for locations with the least biodiversity value and then identified the location with the next lowest level of biodiversity value. This process continued until there was a complete ranking of locations across the state. The biodiversity value that informed the ranking was based on the modelled range and likelihood of species habitat or vegetation type in a location, compared to pre-settlement levels. This iterative, bottom-up approach is used so that the analysis considers the connectedness and aggregation of habitat at the same time as the representation of values. This analysis results in the areas with little biodiversity value ranked lower, the most degraded and poorly located examples of the most common habitat or vegetation in the middle of the ranking, and the best and most well-connected examples of VROT species' habitats across the state ranked higher. This means that some locations with low condition vegetation can be more highly ranked because they provide links for habitats, or are the only remaining habitat for certain species. For some species, significant areas of likely habitat may not be occupied, either due to insufficient recovery time since a disturbance event or due to catastrophic historic impact that is beyond normal recovery capability. These factors are not yet included in Habitat Importance Models nor in the current SBV map.
