Abstract

Underground coal mining is the dominant method of extracting thermal and coking coal in the southern and western coalfields of New South Wales (NSW). Monitoring of mining-related subsidence forms an important component of environmental impact assessments and subsidence management plans, particularly when there are conflicts between the requirements of mining, environment and the interests of community groups. However, the limited guidelines for monitoring impacts of subsidence on terrestrial and aquatic ecosystems has led to inconsistent policy approaches and variable capabilities of monitoring programs to accurately detect biological change. This paper highlights the use of a conceptual framework to guide the development of a long-term ecological monitoring program at an underground coal mine in the western Blue Mountains, NSW. Two pilot studies are described: 1. determining the level of observer agreement to assess the condition of a vulnerable tree species (Capertee Stringybark) 2. comparing field sampling methods for detecting a rare heath shrub Epacris muelleri, using a power analysis to determine sampling intensity requirements. The different examples demonstrate that investment in pilot studies to test monitoring approaches can have long-term benefits for proponents and stakeholders by more confidently being able to detect potential impacts.
