Nesting climate refugia for southwest Pacific loggerhead turtles
Emily Webster
28 Feb 2025 - 30 Jun 2026
To develop a scalable spatial analysis to identify climate refugia for nesting loggerhead turtles. Refugia is defined as areas of current suitable nesting habitat whose exposure to threatening climactic variables is predicted to remain stable over time. the project will consider predicted sea level rise, erosion and temperature change at current and future scenarios. By comparing current and future levels of exposure to these climatic variables, maps that identify areas of imminent loss (exposure to climatic threats predicted to increase), novelty (exposure decreases) and refugia (exposure remains stable) can be developed. the project will also examine geomorphology of the coastline to map the current suitable nesting habitat and quantifying the vulnerability of that habitat to specific climatic and anthropogenic threats.
Improving land condition across Southern Gulf rangelands to build resilience to variable and extreme climate

Grant: https://www.business.qld.gov.au/running-business/environment/natural-resource-funding/apply#key-dates Project description: Recent extreme climatic events (e.g., the 2019 flood and preceding drought, and the 2023 flood) have had a devasting impact on the Southern Gulf’s grazing industry and local communities, as well as the health and functioning of the region’s sensitive natural assets, including soils, pastures, water, and biodiversity. The occurrence and severity of such extreme climatic events are predicted to increase into the future. The overarching aim of the project is to build resilience in Southern Gulf rangeland production systems to better manage climate variability and extreme climatic events, through improving land condition. Land that is maintained in good condition is less susceptible to severe impacts associated with extreme climatic events and recovers more quickly after events occur. To achieve improved land condition across the region, the project will work directly with X land managers to implement on-ground land management practice changes and/or remediation treatments, spanning an estimated area of X. The effectiveness of these interventions will be rigorously monitoring and evaluated, and the data made publicly available. Key learnings and outcomes will be passed on to the other landholders, NRM groups, Government extension staff and researchers through demonstration sites, field days, communications materials, scientific publications, and capacity building events. Overall, the project will provide much needed new knowledge, information, data, tools, and capacity to better manage and respond to climate variability and extreme climatic events across the Southern Gulf region, and other parts of northern Australia.
Bowen Wharf Baseline Environmental Assessments
Michael Rasheed
16 Apr 2025 - 31 Dec 2026
In preparation of development of the Bowen Wharf, North Queensland Bulk Ports (NQBP) have engaged TropWATER to fill information gaps on marine habitats and marine megafauna to help inform approval processes for development. Information on seagrass habitat, coral and megafauna were identified as knowledge gaps in the recent Bowen Wharf Environmental Values Assessment. This project will address these knowledge gaps through; on-ground assessments (i.e., low-level aerial surveys (UAV & MAV), on-foot surveys, subtidal surveys using underwater camera systems), vessel-based field observations, and remote imagery.
Alluvial Gully Remediation in the Upper Burdekin Catchment (Old ID 27857)
Jack Koci
14 Nov 2022 - 15 Jun 2026
In catchments draining to the Great Barrier Reef World Heritage Area, northeast Queensland, Australia, excess sediment derived from gully erosion is contributing to poor coastal water quality. Remediating and preventing further degradation of these landscapes is a major focus of investment toward improving coastal water quality. This project will monitor and evaluate the effect of several alluvial gully remediation measures on improving water quality in the Upper Burdekin catchment. The project will provide valuable new data, knowledge and understanding of the effectiveness of these remediation approaches for landholders interested in protecting and enhancing forage productivity, and for the organisations investing in activities to reduce sediment and nutrient loads delivered to the Great Barrier Reef.
Expanding Traditional Owner led seagrass monitoring and restoration – Woppaburra TUMRA
Len McKenzie
21 May 2025 - 31 Mar 2026
This project aims to build seagrass assessment and restoration capacity and identify seagrass cultural values within Woppaburra TUMRA Sea Country and communities. JCU will work with Woppaburra TUMRA Aboriginal Corporation and rangers to: • synthesize and collate all existing seagrass mapping data. These data will identify seagrass mapping gaps and will inform further seagrass monitoring and restoration activities. • build capacity of Rangers to conduct seagrass assessments. • map Sea Country using drones and dropcameras, for areas identified as needing mapping.

Improving land condition across north-west Queensland to boost productivity, build climate resilience and increase biodiversity
Jack Koci
15 Jul 2024 - 30 Jun 2028
Across the Southern and Northern Gulf region of north-west Queensland, there are many thousands of hectares of land in poor condition. Land that is in poor condition is less productive and therefore profitable, more susceptible to severe impacts from extreme climate events (e.g., floods and droughts), has a lower capacity to sequester and store carbon, and negatively impacts other ecosystem services (e.g., biodiversity and water quality). The overarching aim of the project is to build resilience in Southern and Northern Gulf rangeland production systems through improving land condition. To achieve improved land condition across the region, the project will work directly with land managers to implement on-ground land management practice changes and/or remediation treatments. The effectiveness of these interventions will be rigorously monitored and evaluated. Key learnings and outcomes will be passed on to the other landholders, NRM groups, Government extension staff and researchers through demonstration sites, field days, communications materials, scientific publications, and capacity building events. Overall, the project will provide much needed new knowledge, information, data, tools, and capacity to boost productivity, build climate resilience, and facilitate access to emerging environmental markets across north-west Queensland, and other parts of northern Australia.
