The Gunn Point Area covers approximately 71,000 ha. and is defined by the Howard Water Allocation Planning Areas north of Gunn Point Road to the coastline. Flora surveys were undertaken between July 2018 and March 2019 to locate threatened plants, update species habitat models, and to refine mapping of sensitive and significant vegetation communities. Fauna surveys targeting threatened mammals, owls and frogs were undertaken between June 2018 and February 2019. The aim of the assessment was to identify biodiversity values to support sustainable development of natural resources and to de-risk investment. The risk to biodiversity classes were developed to assist land use planning and development. This information is part of the Mapping the Future Project - Gunn Point This project has identified land capability, water availability and biodiversity values to support land planning and inform development potential over the Gunn Point area.

Attribute values are assigned to each polygon and described in the Data Dictionary below. The attribute naming format uses 10 characters with no spaces to be suitable for an ESRI shape-file format. An alias attribute name is applied to an ESRI file geo-database format.0Biodiversity values were identified in the Gunn Point area from vegetation communities mapping (Vegetation Communities of the Gunn Point Area (2020), species habitat suitability modelling and targeted flora and fauna surveys (Biodiversity Assessment of the Gunn Point Area (2020), and historical species location records derived from the Department's Flora Atlas and Fauna Atlas. Biodiversity values data were compiled into five classes. The data source for each class was kept in the final output. Descriptions for the classes are noted in the Data Dictionary in this metadata record. - Class 1. Remnant vegetation not present - Class 2. Project area including defined polygons for waterbodies - Class 3. Areas with high likelihood of containing important habitat for threatened species (Typhonium praetermissum, Cycas armstrongii, Stylidium ensatum) - Class 4. Sensitive and significant vegetation communities - Class 5. High biodiversity value areas The five biodiversity values classes were unioned using ArcGIS 10.6 software. A Risk to Biodiversity ranking was compiled to resolve overlapping attributes for each class. Each selection will overwrite any previous selections. Select C3_Class = 3; create BioRisk = 3 Select C4_Class = 4; create Bio_Risk = 4 Select C5_Class = 5; create Bio_Risk = 5 Select C1_Class = 1; create Bio_Risk = 1 Select BioRisk = 0 (remaining polys); create BioRisk = C2_Class (keep 0, 2 or 9 values)
