Projects

Climate change poses a major threat to the biodiversity of New South Wales. Increasing temperatures, shifts in rainfall patterns, rising sea levels and increases in the intensity and frequency of extreme events are projected to affect population sizes, species ranges, the timing of life cycles, the structure and composition of ecological communities and extinction risk.

Our projects are all co-developed by academic researchers and government scientists to ensure the outputs are policy-relevant and provide an effective basis for conservation planning under climate change.

Risk assessment and webtool (WeedFutures) for exotic plants under future climates

This project assessed the extent of suitable habitat for 700 non-native plants within Australia under current and future climate conditions and produced an interactive, online decision-support tool (weedfutures.net) to assist natural resource managers conduct weed risk assessments and prioritise monitoring and management actions across species.

Identifying regions of high drought-mortality risk for tree species in NSW

Severe drought can cause large-scale forest death, transforming landscapes and thus having potentially catastrophic consequences for biodiversity. This project aimed to promote conservation planning for key tree species under a range of future climate change scenarios by quantifying the risk of drought mortality across New South Wales.

The project was a collaboration by Macquarie University, the University of Western Sydney and OEH, and has been awarded Australian Research Council funding.

Horizon scanning for potential future pests and pathogens in NSW

The exclusion, or early detection and eradication, of exotic pests and pathogens is consistently shown to be more cost-effective than efforts to manage or contain invasive species once established. This project will collate global data on the likelihood of potential pests and pathogens becoming invasive in NSW and will assess their impact on biodiversity. Horizon scanning and risk analysis are undertaken under current and future climatic conditions to identify high priority species for the development of targeted management plans.

Wildlife disease surveillance

Patterns have been observed between climate cycles, including El NiƱo events, and outbreaks of wildlife diseases that use insects as vectors (arboviruses). This project examined the relationship between climate and arboviruses using field data contained in the Australian Registry of Wildlife Health (the Registry) and used models to identify climate-­related risk factors for expansion of wildlife disease emergence.

Incorporating climate change into the Saving our Species Site-managed stream

In the Saving our Species program, threatened species that are classified as site-managed have a conservation plan developed for them that identifies sites for management, and appropriate management actions at those sites, to support their long-term persistence. This project developed a decision-support framework and tool for selecting sites for management of threatened species.

Identifying climate refugia for key species in New South Wales (Climate Refugia NSW)

This project identified climate refugia and assessed the potential for species to shift their distributions to track moving climate zones by considering barriers to movements, current land use patterns, landscape connectivity and health, connectivity with existing protected areas and species-specific list history traits. Maps are available on the refugia website, along with functions to search for species and generate reports for different regions.

Using plant traits to assess threatened species adaptive capacity under climate change

This project assessed the adaptive capacity of threatened plants using a trait-based approach to classify species relative to four key areas: dispersal capacity, reproduction, level of specialisation and spatial scale. The outputs included recommendations of a suite of management actions for taxon groupings.

Assessing the vulnerability of threatened species and ecosystems to climate change

This project assessed the vulnerability of threatened species and ecological communities to climate change. Species listed as threatened under the Threatened Species Conservation Act 1995 and with Final Determinations were assessed and future habitat suitability was modelled for a subset of these. This project produced a searchable web tool NSW Threatened Species that allows users to find information on the key threats affecting threatened species, including specific climate threats.Since the completion of the report, the website has been updated to include those species listed under the Biodiversity Conservation Act, 2016.

Predicted effects of climate change on freshwater biodiversity

Freshwater species are potentially highly susceptible to the effects of climate change, especially with the increased difficulties they are experiencing in dispersing between catchments. This project established a baseline dataset covering the distribution of freshwater species in NSW across a wide range of taxonomic groups. Projections of future distributions under climate change identified key vulnerable groups. This project released a final report titled Priorities and uncertainties or predicted impacts of climate change on freshwater biodiversity in New South Wales.

How does an adaptation lens change the way we invest in landscapes for biodiversity?

Considering the ways in which landscapes are likely to change through time may change what outcomes are feasible to achieve, along with the mix, timing and location of activities that are targeted for investment. This project analysed the ability of existing decision processes to incorporate dynamic changes to threats and explored options to incorporate climate adaptation into future decision-making.

Bioclimatic discordance: Combining molecular and environmental data to identify floristic refugia and corridors

The analysis of molecular data can distinguish between areas that have previously served as population refugia and differentiate them from expansion areas. By combining data from select species of rainforest trees, this project identified the landscape features and areas that have operated as refugia during temporal climatic fluctuations which can inform predictions of where future floristic refugia may occur.

Evaluating the status of the NSW terrestrial reserve system under a changing climate

Climate change jeopardises the capacity of the reserve system to maintain its CAR principles because it drives change in species ranges. This project evaluated the status and impact of a changing climate on the comprehensiveness, adequacy and representativeness (CAR) of the NSW terrestrial reserve system and identified priority areas for future reservation under climate change.

Ecological range metrics for the entire NSW flora (NSW Niche Finder)

Basic metrics of plant ecological range are routinely used to assess the vulnerability of species to human-induced impacts, particularly climate change. However, we currently lack this type of baseline ecological data for the NSW flora. This project examined the range, climate niche breadth and the diversity of soil types occupied by each species in the NSW flora. The metrics are available online at NSW Niche Finder where users can explore baseline maps of ecological ranges and access climate niche metrics of NSW plants.

Best practice translocation guidelines for climate-change adaptation in NSW

The rapid pace of climate change is expected to increase the risks to species because many habitats will become increasingly unsuitable, and rates of migration to new habitats may be too slow and individuals may face insurmountable barriers. Translocation to new areas may be necessary to prevent either local or global extinction. The aim of this project was to provide a comprehensive overview of assisted colonisation for climate-change adaptation, along with advice on effectively translocating those species in NSW that might suffer population declines.
