Strategic Alliance - Onshore Environmental

Onshore Environmental Consultants

Onshore Environmental Consultants (OEC) specialises in baseline flora and vegetation surveys, regulatory reporting, development and implementation of mine site rehabilitation strategies, rehabilitation and baseline monitoring, and impact assessment. The Biological scientists employed are capable of undertaking specialist Biological surveys for a variety of clientele throughout Western Australia. The major objective of the Company is to provide high quality environmental advice to our clients.


Flora and Vegetation

In addition to the need for baseline botanical survey work associated with land disturbance for major projects, new clearing legislation has focused the spotlight on the need to obtain specific approval in all instances where native vegetation may be cleared or disturbed. These regulations were implemented to control and minimise the destruction of flora and vegetation with conservation value. Approvals require detailed information on the conservation significance of vegetation and flora. Botanical staff at OEC specialise in:
  • Baseline multi-season flora and vegetation surveys;
  • Vegetation mapping surveys;
  • Targeted Declared Rare (DRF) and Priority Flora surveys;
  • DRF or Priority flora monitoring surveys;
  • Vegetation condition assessments; and
  • Regional conservation value assessments.
Team Profiles

Dr Darren Brearley

Darren holds Bachelor of Science degrees in Botany (University of Western Australia) and Environmental Biology (1st Honours Curtin University of Technology), along with a PhD from Curtin University of Technology. For the past 14 years he has been involved with a variety of research and consultancy projects throughout Western Australia, Victoria and New South Wales.

Darren's primary expertise is related to botanical survey and vegetation mapping, and the development, implementation and monitoring of post-disturbance rehabilitation strategies. Between 1997 and 2000 he was employed as Research Fellow on a three year Minerals and Energy Research Institute of Western Australia (MERIWA) funded project, investigating the development of completion criteria for arid and semi-arid mine sites in Western Australia. He has also managed projects that have incorporated fauna surveys and research into the limnology of ephemeral salt lakes.

In February 2001 Darren established Onshore Environmental Consultants Pty Ltd, which he continues to operate in 2008 as a Director and Senior Environmental Consultant.
Dr Jerome Bull - Senior Botanist

Jerome is a fully qualified botanist and environmental scientist with over ten years consulting experience, and has recently completed a PhD on plant-animal interactions at the University of Western Australia.

Jerome has been responsible for managing a number of projects in Western Australia. His responsibilities have included guiding a variety of botanical projects in the eastern Goldfields, Kimberley, Pilbara and Swan Coastal Plain and have involved the coordination of assistants, liaison with clients, and interaction with government bodies. He is experienced in undertaking baseline flora and vegetation surveys, rare flora searches, vegetation mapping and bushland condition assessment. Jerome has an excellent knowledge of the temperate flora of Australia and recently discovered a new species of plant in the Goldfields region of Western Australia (Tetratheca erubescens J.Bull ms).
