Flora, Fauna & Biodiversity Surveys

JWA Pty Ltd has extensive experience in the completion of flora and fauna surveys in a wide range of vegetation types and ecosystems.

For flora surveys we use:

  • the latest aerial photography to map community types,
  • stereoscopic photography,
  • ground truthing of existing vegetation maps,
  • random and quadrat surveys for flora species, and
  • targeted threatened species searches.

For fauna surveys we use:

  • opportunistic and systematic daytime surveys for mammals, birds and reptiles,
  • spotlighting and call playback for nocturnal birds and mammals,
  • targeted surveys for threatened fauna species,
  • spotlighting and auditory surveys for amphibians,
  • trapping for small mammals (both arboreal and terrestrial),
  • ANABAT (an electronic call-detecting device) to survey for Microchiropteran bats, and Pitfall surveys.
Impact Assessments

Impact assessment techniques involve:

  • mapping flora, significant plant communities and threatened plant species,
  • fauna surveys and habitat assessment. Identification of threatened fauna species or their likelihood of occurrence,
  • calculating the loss of vegetation (i.e. community types), threatened flora and fauna and their habitat,
  • consideration of direct and indirect impacts, and
  • consideration of Local, State and Commonwealth legislation.

JWA Pty Ltd provides advice on Commonwealth and State environmental and planning legislation including the:

  • Commonwealth Environment Protection & Biodiversity Conservation Act (1999)
  • QLD Sustainable Planning Act (2009)
  • QLD Nature Conservation (Wildlife) Regulation (2006)
  • QLD Vegetation Management Act (1999)
  • QLD Nature Conservation Act (1992)
  • NSW Native Vegetation Conservation Act (2003)
  • NSW Threatened Species Conservation Act (1995)
  • NSW Environmental Planning & Assessment Act (1979)
  • NSW State Environmental Planning Policy (SEPPs)

We undertake Assessments of Significance (7-part tests) and complete Species Impact Statements (TSC Act 1995), Koala Assessments (SEPP 44) and assessments for matters of National Environmental Significance (NES) (EPBC Act 1999) to accompany development applications. We understand the unique challenges development poses within the native environment, so we can provide advice on mitigating impacts in order to produce a sustainable outcome.

Environmental Management Plans

After collecting comprehensive data on the flora, fauna, vegetation and overall biodiversity of a site, JWA Pty Ltd can provide clients with an Environmental Management Plan. Such a plan, or series of plans, provides strategies for the:

  • rehabilitation and restoration of conserved native vegetation,
  • restoration of native vegetation and fauna habitat,
  • restoration of significant ecosystems,
  • management of threatened flora and fauna species,
  • control of weeds, and
  • control of feral animals.

We can provide advice for both the construction and operational phases of the project and develop monitoring and reporting strategies to ensure the overall objectives are reached and compliance with consent conditions is achieved. We can also provide a team of experts to implement our Environmental Management plans or those developed by others.

Mining Rehabilitation

JWA Pty Ltd has the experience and resources to provide our mining clients with the range of environmental services required, from the pre-operational, operational and closure stages of a project. We can provide:

  • baseline ecological surveys,
  • impact assessment,
  • mitigation strategies,
  • environmental policy and strategic advice,
  • environmental management plans including detailed rehabilitation plans and advice including species selection and rehabilitation techniques, and monitoring programs and reports to meet consent conditions and statutory requirements.
Biobanking / Offset Assessment

JWA Pty Ltd is skilled in negotiating biodiversity offsets, that is, positive actions to compensate for biodiversity loss arising from development. We have a proven track record of managing development while maintaining and restoring biodiversity. Firstly, we provide a constraint analysis for the development site to avoid impacts, then we work in conjunction with our clients to provide mitigating strategies and/or compensatory measures through offsetting, creating opportunities for private sector conservation land management.
