NESP 4.11: Scaling-up long-term seagrass restoration in the Cocos (Keeling) Islands
Paul York
05 Feb 2024 - 04 Jan 2027
There is an urgent community-driven need to develop appropriate seagrass restoration approaches at scale for the Cocos (Keeling) Islands (CKI). Fast-tracking larger-scale restoration research is required to prevent imminent collapse and functional extinction of seagrasses at CKI due to past disturbance and current green turtle grazing pressure. This project builds on pilot studies to design and establish a network of larger-scale turtle exclusion areas where locally appropriate restoration approaches can be refined. At the same time, this will provide “seagrass refuges” to initiate recovery, monitor ecological effects, and provide for future restoration efforts. The project has been co-developed with the CKI community and Parks Australia, addressing their highest research priority identified in the newly established Cocos (Keeling) Islands Marine Park. The project will provide an action plan for ongoing interventions and strategies to future-proof local seagrasses and support seagrass-dependent species, such as green turtles and fish, in the long term.

Tiwi Islands seagrass surveys and development of ranger-led monitoring program
Alexandra Carter
01 Mar 2024 - 30 Jun 2027
Tiwi People aspire for a healthy, managed Sea Country and to establish an integrated Marine IPA (MIPA). Tiwi Sea Country estate has high cultural and biodiversity significance, but this is poorly documented. The presence of important species such as dugong and turtle is known, but habitats important to these species has not been quantified. Collecting data efficiently and co-designing monitoring that rangers can maintain in their workplans is a priority of the Tiwi rangers. Subtidal seagrass needs to be mapped and monitoring of these habitats designed for rangers to implement. We will: • Participate in On-country consultations and knowledge sharing sessions (timing to be determined) • Co-design subtidal benthic habitat surveys with Tiwi Resources • Undertake benthic habitat surveys using a drop camera in collaboration with Tiwi sea rangers • Analyse drop camera images, create maps and prepare draft data report • Co-design and undertake two years of monitoring in collaboration with Tiwi sea rangers • Purchase underwater camera system for Tiwi sea rangers • Contribute to progress reports from Tiwi Resources to the Northern Territory Government as needed
NESP 3.4 Better management of catchment runoff to marine receiving environments in northern Australia. (Old ID 28969)
Paula Cartwright
01 Feb 2023 - 30 Jun 2024
Runoff from catchments in northern Australia has the potential to carry large amounts of sediment and nutrients. These available nutrients are important in driving coastal and estuary productivity, including many commercially and recreationally targeted species. Water resource development in northern Australia could reduce the supply of freshwater flow to the coast, thereby limiting supply of nutrients. This research project will examine the potential risks water resource development presents to Gilbert (QLD), Daly (NT) and Ord (WA) marine and coastal areas. We will complete a literature review, undertake flood plume modelling and examine vegetation damage along these coastal areas.
Ecotoxicology of pesticides on the Great Barrier Reef for guideline development and risk assessments (Old ID 23137)
Aaron Davis
01 Jan 2017 - 10 Mar 2020
Over 50 land-sourced pesticides have been detected in waters of the Great Barrier Reef (GBR) and its catchments. Previous studies on the risks posed by pesticides have focused on five priority PSll herbicides. However, other pesticides are increasingly being used, for which there are few fate, persistence and toxicity data. In order to improve water quality guidelines and assessments of the potential risks posed by these ' alternate' pesticides to GBR and its catchments we will quantify their toxicity to freshwater and marine species.

Spatial and temporal trends in the health and resilience of Great Barrier Reef inshore seagrass meadows in relation to water quality (Old ID 20687)
Catherine Collier
01 Dec 2012 - 30 Aug 2027
The aim of this research is to monitor the abundance and species composition of seagrass, and identify areas of seagrass that have been significantly impacted by flood plumes in areas important to major dugong populations in the Great Barrier Reef World Heritage Area.
Ecological valuation tools to protect seagrasses from coastal development (Old ID 22415)
Paul York
24 Nov 2015 - 31 Dec 2018
Industry cash contribution fro ARC Linkage Grant application LP160100492. Seagrasses provide ecosystem services (fisheries, nutrient cycling, primary productivity) worth trillions of dollars, but this capacity is threatened by coastal development. In Australia, port developments are considered a major threat to seagrass ecosystems, but resource managers lack accurate information about their potential impacts and mitigation lmeasures. Focussing on differences between shallow and deep seagrasses within the Great Barrier Reef, this project seeks to develop a world-first spatial valuation tool that will allow resource managers and policy makers to minimise impact of port development on seagrass ecosystems, thereby ensuring that Australia's seagrasses continue to provide ecosystem services essential to our well-being.
Hay Point Shiploader Upgrade: Benthic Habitat Assessments (Old ID 26698)

Mangrove Watch in Easterna Normanby Basin with Kalpowar Land Trust (Old ID 21778)
Norm Duke
15 Apr 2014 - 20 Dec 2018
Mangrove Watch boat and aerial surveys will be conducted in Princess Charlotte Bay with local indigenous rangers to assess existing values, threats, future issues with climate change and restoration and protection options for tidal wetland habitat in Princess Charlotte Bay. This project aims to enhance biodiversity values, increase ecosystem service provision, including carbon sequestration and improve habitat connectivity within princess Charlotte Bay and the Normanby River.
