Project: Toorale and Gundabooka Nature Tourism Action Plan

OzArk has worked with NSW National Parks and Wildlife Service to prepare an Aboriginal Cultural Heritage Assessment Report (ACHAR) to identify Aboriginal objects (sites) within the development footprint for a Wetland Experience themed visitor facility.

The field survey involved a pedestrian survey in partnership with members of the Toorale Joint Management Committee, registered Aboriginal parties and a NPWS Field Officer. An additional 28 Aboriginal sites were recorded, which were added to the 14 previously recorded sites, resulting in 42 Aboriginal sites being present within the impact footprint. Management measures have been recommended to manage these impacts to the Aboriginal sites.

The Hera Project is a gold, silver, lead and zinc mine, along with a processing plant and related ancillary infrastructure.

OzArk EHM was involved in completing the initial surveys and reporting required to assess the scientific values present. The impact area is a 1,532 hectare area proposed for the operation of the Hera Mine.

Extensive flora surveys were undertaken, using scientifically approved methods and involved using quadrats and transects . Fauna surveys included spotlighting, dedicated bird surveys and herptofauna searches, Elliot and Pitfall trapping, Anabat detection, call playback and incidental observations.

The results of the ecological assessment have been used in the development approval process.

Once the mine became operation, OzArk completed annual ecological and biodiversity monitoring on non-operational land.

OzArk is working with the Central West Local Land Services (CW LLS) to assess the impact of cultural burning in travelling stock routes. Prior to burning commencing, and in conjunction with local Aboriginal representatives, OzArk Archaeologists carried out an Aboriginal archaeological assessment. Seven Aboriginal sites were identified and management recommendations provided.

OzArk Ecologists also worked with CW LLS staff before burning to determine  baseline ecological data.  Post-burn assessment is undertaken to be able to analyse data and determine the ecological impact of cultural burns. This is an on-going project with regular monitoring important to ensure replication and robust data analysis. CW LLS hope to apply the results across other travelling stock routes.
