A huge thank you to everyone who joined us for our Landcare Children’s Play with Clay Day! It was a delight to see creativity flow as the children crafted some truly wonderful and unexpected creations from clay.

From beautiful kokedama to squishing seed bombs in little hands, their imaginations knew no bounds!

We had a fantastic time together on that cool spring morning, filled with laughter, chatter, and fun. The excitement and joy on the children's faces made the day even more special, as they embraced this hands-on, nature-based experience.

Your participation helped make this event a success. We look forward to more moments like this in the future!

Recently, a small team gathered to mix Climate Ready seed for another exciting year of sowing and growing plants for local revegetation. Over 280 packets of seed were handled on the day! 

These seeds came from a wide variety of provenances across NSW, Victora, and Queensland, with the aim of enhancing the genetic diversity of the 40 species on YAN’s Climate Ready nursery list. Greater genetic diversity gives local plant populations the best chance to adapt to a changing climate over successive generations.

The seed has been distubuted to YAN's three nurseries - Murrumbateman Landcare Nursery, Yass Landcare Nursery, and Bowning-Bookham Landcare’s Wattle Valley Nursery – as well as the Alexander Maconochie Centre’s nursery. Most of the seed will be sown this spring, with the resulting seedlings available for planting in autumn 2025.

Four new local species will be grown in the nurseries this year: Calytrix tetragona (Common Fringe Myrtle), Dianella revoluta (Black-anther Flax-lily), Einadia hastata (Berry saltbush), and Pultenaea spinosa (Grey Bush-pea).

The annual Climate Ready seed sorting day is the culmination of meticulous work which includes assessing species for future climate resilience, identifying suitable seed provenances, sourcing seed from commercial retailers, testing germination, and maintaining detailed records of all activities.

Seed sorting requires concentration and coordination and typically takes the team most of the day to complete. However, it is also a great opportunity to catch up, enjoy a shared lunch, and this year, we were treated to a delicious homemade fruit cake.

The annual Climate Ready seed sorting day is the culmination of meticulous work which includes assessing species for future climate resilience, identifying suitable seed provenances, sourcing seed from commercial retailers, testing germination, and maintaining detailed records of all activities. All of the native seed purchased by the Climate Ready project was funded through the Landcare Australia Michael King grant - our project volunteers appreciate this funding as seed costs are increasing each year.

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.
