Abstract

Onshore seismic surveys are traditionally associated with wide straight tracks, required for access by seismic vehicles and denuded of vegetation. The proposal by Lasmo Oil (Australia) Ltd and its co-venturers to perform a seismic survey on the Muiron Islands Nature Reserve was therefore received with some concern by residents of nearby Exmouth in Western Australia. The proponent undertook extensive surveys of the existing environment, however, and produced a strict environmental management plan which featured innovative methods to minimise impacts on both flora and fauna — in particular the extensive Wedge-tailed Shearwater colony on the islands. These methods were executed much as planned and caused negligible destruction of vegetation and no known bird mortality. The results indicate the management plan was highly successful and established a new benchmark for exploration in sensitive areas.This paper outlines the environmental management plan developed for the work and documents the results of the procedures employed. It concludes that such methods could be applied to similar projects elsewhere.
