The Climate Ready Revegetation (CRR) team recently met to refine our approach in selecting native plant species for nursery propagation. This effort is crucial in adapting our local ecosystems to future climate conditions in the Yass district.

Selecting Species for the Future

A key part of the discussion centred on the methodology for deciding which species our partner nurseries will grow. We have always used ‘scatterplot’ graphs to assess whether a species currently occurs in climates like what we can expect in the Yass region in the future. The team decided that we  will now also start using maps that show the distribution of different plant species in relation to projected future climate conditions. These maps highlight areas with similar temperatures and precipitation levels to what we expect in Yass by 2070 and provide important geographical information about where species occur.

The outlined area roughly shows the overlap of temperature (5-95th percentiles) and precipitation (5-95th percentiles), indicting the future climate analogue area for Yass (RCP8.5, for 2070)

Our 2070 climate projections come from the My Climate View website, based on the Representative Concentration Pathway (RCP) 8.5 scenario. This scenario assumes high greenhouse gas emissions and presents a worst-case climate outcome, making it a robust tool for future-proofing our species selection. These projections can be mapped using the Atlas of Living Australia’s spatial analysis tool, as shown in the images on this page.

Climate Maps: A New Lens for Decision-Making

When assessing a species’ future climate tolerance, we mostly focus on two climate variables : annual average temperature and precipitation. Although other variables like soil type, seasonality of rainfall, and extreme weather events are also likely to be significant, annual average temperature and rainfall are a good starting point for determining which plants may thrive under future conditions.

Using this data, the team assesses the prevalence of a species in the projected climate overlay for the Yass district (known as a ‘future climate analogue area’). We aim to select species that naturally occur in this area, as they have a better chance of surviving and flourishing as the climate shifts.

Eucalyptus melliodora distribution (left) is one of the species included in the CRR project as it occurs not just in the Yass region, but in the future climate analogue area. Eucalyptus polyanthemos subsp. polyanthemos (right) currently grows well in the Yass region but does not occur in the future climate analogue area.

Enhancing Genetic Diversity for Adaptability

Once species are shortlisted, we evaluate the availability of seed from various provenances—different geographic locations where the species naturally occur. By sourcing seed from a range of provenances, we aim to increase the genetic diversity of plants grown in our nurseries and used in local revegetation  efforts. Genetic diversity,  boosts the likelihood of these species adapting to changing conditions over time. By increasing genetic variation, we hope to encourage natural selection processes that will allow the species to survive and adapt to the changing climate.

Field Insights: Monitoring Adaptability

Following the meeting, the team visited one of our CRR trial sites where we are monitoring the survival of three species grown from local and non-local seed. This trial is essential for understanding whether plants grown from non-local seed are able to survive in local conditions. Results so far indicate that there is no significant difference in the survival of plants grown from local or non-local seed, which gives us confidence to continue our work.

Get Involved with CRR

The CRR team meets regularly throughout the year to assess progress and refine our methodologies. This ongoing work is one of the many critical tasks CRR volunteers undertake to build a climate-resilient future for our native species.

If you’re interested in learning more about the Climate Ready Revegetation Project or would like to get involved, please contact Sonya Duus, our Climate Ready Revegetation Project Officer [email protected]. Together, we can help safeguard the future of our local ecosystems through thoughtful, science-backed action.

This project is part of YAN’s broader commitment to environmental stewardship and community involvement. We welcome anyone passionate about preserving our natural landscapes to join us in this important work.

Recently, the CRR project team (Sue McIntyre, Sonya Duus & Gill Hall) had the exciting opportunity to present their work at the Australian National University, invited by Professor Jamie Pittock of the Fenner School. The team was invited to speak to a class of Masters students in the "Climate Change Vulnerability and Adaptation" course, focusing on how down-scaled climate projections can help address the impact of climate change on native plants.

Sue kicked off the session with an insightful presentation on the science behind climate change and its effects on biodiversity, setting the stage for Sonya to dive into the specifics of the CRR project. The students were introduced to the project’s innovative approach to using data to safeguard native species.

Following the presentations, Gill and Sonya guided the students through a series of practical exercises, both face-to-face and online. These activities introduced students to publicly accessible tools such as My Climate View, Atlas of Living Australia, Climate Analogue Explorer, Restore and Renew, Which Plant Where, and NSWNicheFinder). The practical exercises were designed to help students explore climate impacts and potential adaptive strategies using real-world data.

The engagement level was excellent, with students asking thoughtful questions and providing positive feedback. It was a great opportunity to share the tools and techniques developed by the CRR team, and we’re hopeful these future leaders will apply some of these strategies in their own climate resilience work across the globe.

This experience highlighted the value of collaboration and knowledge sharing in tackling the global challenge of climate change. We look forward to more opportunities to connect with emerging leaders and share the impactful work being done by the CRR project.

As we celebrate Threatened Species Day, it's important to shine a spotlight on the vulnerable Glossy Black-Cockatoo, a spectacular bird that depends on our efforts for its survival. One of the most effective ways to support this species is by planting its favourite food source, the Allocasuarina trees.

A Specialised Diet

The Glossy Black-Cockatoo has a highly specialised diet, feeding almost exclusively on the seeds of she-oaks (Allocasuarina and Casuarina species). Although they feed on at least nine species of she-oak across their range, within local areas, their feeding is often restricted to a single species. In South-East Queensland and North-Eastern New South Wales, they show a distinct preference for the Black She-oak (Allocasuarina littoralis) but will also eat seed for the Drooping She-oak (Allocasuarina verticillate).

A Call to Action for Landholders

Your local YAN Landcare nurseries grow both Allocasuarina littoralis and Allocasuarina verticillata. This is a fantastic opportunity for landholders to create new feeding areas for the Glossy Black-Cockatoo by planting these essential trees.

Why Allocasuarina littoralis?

Allocasuarina littoralis is a versatile and resilient tree that can thrive in a variety of soil types, from sandy soil to heavy clay and rocky ground. It is perfect for ridgelines and anywhere in between, growing to a mature height of 5-15 meters. By planting Allocasuarina littoralis, you can help ensure that the Glossy Black-Cockatoo has a reliable food source throughout the year.

The Drooping She-oak: Another Option

In addition to Allocasuarina littoralis, YAN nurseries also grows Allocasuarina verticillata (Drooping She-oak), which naturally occurs in the Yass Valley. This tree grows to a height of 4-10 meters and is particularly suited to ridgelines, making it another excellent choice for supporting the Glossy Black-Cockatoo.

Planting Tips

When planting these trees, remember that they are dioecious, meaning they have separate male and female plants. To ensure seed production, you'll need to plant several trees in close proximity. Small groups are best for encouraging seed set and providing ample food for the cockatoos.

How to Get Involved

To contribute to the survival of the Glossy Black-Cockatoo, consider pre-ordering some Allocasuarina littoralis or Allocasuarina verticillata for your autumn planting through the YAN Online Plant Request Form. By doing so, you can help create new areas of food sources for these beautiful birds.

Further information about the Glossy Black Cockatoo can be found at the Glossy Black Conservancy Website glossyblack.org.au

Together, we can make a difference in preserving the Glossy Black-Cockatoo and ensuring its continued presence in our environment. This Threatened Species Day, let's commit to planting the trees that these birds rely on and protect one of our most vulnerable native species.

As National Landcare Week drew to a close, our Bowning-Bookham Landcare group welcomed with a perfect sunny winter's day, ideal for our latest Habitat Hops landscape connectivity project. A enthusiastic group of volunteers, came together to plant nearly 1,000 plants across Glenview, part of our ongoing Habitat Hops landscape connectivity project.

The breeze picked up in the morning, but we were fortunate to be planting close to an adjoining area that had been direct-seeded nearly 20 years ago. This thickly vegetated section provided not only much-needed shelter but also was  powerful visual of what our newly planted seedlings will soon become. It served as a vivid reminder of the long-lasting impact our efforts will have on this landscape.

Children eagerly joined in, their hands busy digging, delivering tree guards, and helping in any way they could. The enthusiasm was infectious. Every volunteer had a role to play—whether it was planting, assembling tree guards, or ensuring the young plants were well-watered.

One of the first sections we planted was aimed at slowing water runoff into an area the owners fondly call the “Grand Canyon.” This effort will help reduce degradation and erosion in that part of the property. Other sections were planted with the goal of creating windbreaks, enhancing habitat, and improving soil health—key components of a resilient landscape.

As we wrapped up the day, there was a collective sense of accomplishment. We had done more than just plant trees and shrubs; we had sown the seeds for a healthier, more connected ecosystem.

A huge thank you to everyone who participated. Your hard work and dedication are what make projects like these possible. Keep an eye out for our next group activity in spring, where we’ll be sowing seeds for next season’s planting.
