Ecosystem health monitoring

An understanding of the status of water quality in Torres Strait and its influence on marine foods, human health, marine ecosystems and ecological processes in the Strait is important.

To guide monitoring, management and mitigation decisions, researchers from CSIRO, JCU and AIMS propose to conduct a Phase 1 study to develop a robust approach that will allow them in Phase 2 to carry out an ecological risk assessment (ERA) of nutrients, fine suspended sediments, and pesticides used in agriculture in the Great Barrier Reef region, including ranking the relative risk of individual contaminants originating from priority catchments to the GBR ecosystems using a systematic, objective and transparent approach.

Phase 1 of the project aims to:

For each of the four Natural Resource Management (NRM) regions between Gladstone and Port Douglas, this project aims to deliver an improved understanding of the quantitative relationships between changing deliveries of suspended solids from their main river ways to the Great Barrier Reef (GBR), and changes in the coastal water clarity within their region.

Monitoring is a fundamental component of the management of threatened species and is of particular importance when those species come into direct conflict with humans and their interests.  In such circumstances up-to-date information on population status, trends and distribution become key inputs into decision making. In these circumstances, systematic, objective and transparent data is critical to the acceptance of the decision making process.

Ten frog species disappeared from the upland rainforests of the Wet Tropics and Eungella during outbreaks of amphibian chytrid fungus (Batrachochytrium dendrobatidis) in the late 1980s and early 1990s, representing 25% of the frogs endemic to the Wet Tropics and all of the Eungella endemics.  Five of these species occurred only in the uplands and have been presumed extinct because no individuals have been found despite intensive searches. This represents a significant loss of endemic species diversity, particularly in the Wet Tropics World Heritage Area.

This project will better characterise biodiversity refugia in north-east Queensland rainforests by assessing genetic diversity at landscape scale in rainforest plants and fungi.

This project will provide detailed mapping of present and future biodiversity patterns and drivers, environmental and evolutionary refugia and a comprehensive assessment of the vulnerability and resilience of rainforest biodiversity in Australian tropical forests. The project team will use a combination of available knowledge, existing datasets and strategic research to inform adaptive strategies for promoting persistence of biodiversity.

This project will develop a Management Strategy Evaluation (MSE) framework using a stakeholder driven approach to qualitatively integrate our understanding of the key drivers of change in the GBR inshore ecosystem and human uses, with an emphasis on biodiversity and inshore multi-species fisheries management.

Torres Strait islands have extensive mangrove margins and several islands (e.g. Saibai, Boigu) are predominantly made up of intertidal swamps (including mangroves, tidal saltpans and salt marsh).  Despite this, there has been no thorough assessment of the diversity, extent and health of mangrove ecosystems there.  Establishing the baseline of mangrove status and condition is important, especially as many islands are low lying and the predictions of sea level rise and increased storm surge frequency mean that mangroves are among the most threatened ecological communities in Torres Strait.
