A small group was at it again this week — collecting leaf samples from Yellow Box (Eucalyptus melliodora) for genetic testing. This time, the focus was on remnant paddock trees — the beautiful giants scattered across our landscape. A 5-metre-long homemade device was needed just to reach some of the lowest branches!

The leaves have now been mailed to our geneticist friends at the Botanic Gardens of Sydney, who will analyse the genetic makeup of each tree. This work will help us better understand the genetic diversity already present in our landscapes — and how much we're enhancing that diversity through the Climate Ready Revegetation project.

Genetic diversity gives plants (and animals) the capacity to adapt to change over generations. That’s why increasing genetic diversity in the tubestock grown at our local Landcare nurseries is a key focus of YAN’s Climate Ready Revegetation project. As the climate gets hotter, we want to give our revegetated areas the best chance to survive and thrive. To increase genetic diversity, we source seed from a wide range of provenances. But the only way to be sure we’re achieving that diversity is through genetic testing. We started sampling back in March, and are excited to learn the results later in the year!

The Climate Ready Revegetation Project has been assisted by the NSW Government through its Environmental Trust. Landcare Australia Michael King grants enable us to purchase seed from diverse provenances.

On a recent autumn evening in Murrumbateman, the Yass Area Network of Landcare Groups (YAN) gathered to celebrate the incredible spirit of volunteerism that drives our Landcare community. At the heart of the event was the presentation of the the groups John Betts Landcare Award, this year awarded to Sue McIntyre in recognition of her outstanding and long-term contribution to Landcare in our region.

The award was presented by Mrs Nanette Betts, on behalf of the Betts family, to honour the legacy of her late husband John Betts—a foundation member of YAN and a tireless contributor to Landcare in the Yass region. The John Betts Award recognises an individual whose efforts have left a lasting impact on Landcare, and Sue’s leadership, dedication, and deep ecological knowledge make her a worthy recipient.

The evening also gave us the chance to recognise the immense contributions of volunteers involved in our Climate Ready Revegetation (CRR) Project. These individuals and groups have collectively contributed up to 4,500 hours in a single year—supporting everything from nursery operations and seed sourcing to ecological advice and monitoring trial plantings.

At our Winter Feast in Yass last year, we began distributing certificates of gratitude to many CRR volunteers. This recent event allowed us to complete that process, with special thanks and certificates going to:

Outstanding Individual Contributions:

• Ann Milligan – for outstanding effort and dedication to seed sourcing
• Elizabeth Goodfellow, Kath McGuirk, Gill Hall, Sue McIntyre – for significant and ongoing contributions to the CRR Project
• Jacqui Stol – for expert advice in ecology, species selection, grant applications, project management and more
• Nola Hancock, AdaptNSW's Climate Adaptation Team, and Alison Elvin – for their expert guidance and support

Nursery Teams:

• Lee Auriac & the AMC Nursery Team – for expertise and outstanding effort in growing plants for the CRR Project
• MLG, Yass Landcare, Bango, and Wattle Valley Nursery Teams – for their commitment and care in growing healthy plants

Hosts of Trial Plantings & Monitors:

• Kath & Richard McGuirk
• Sheridan Roberts & Geoff McFarlane
• Jan Grubb

Hopefully, by the time you read this, the ground will be damp, the dams full and a tinge of green will be gracing the landscape. Meanwhile, I am finding it hard to walk about this parched landscape without feeling down about the dead shrubs and the crunching, desiccated plant life underfoot. Half-empty dams are a sad sight, empty ones are horrible.

Since the huge dump of rain in later spring/early summer when we got about three months of rain in two weeks, we have had a third of the rainfall that we would expect in an average year. The rain we did have, fell in dribs and drabs, evaporating in the heat, and not wetting the profile.

The not very uplifting view of Lake Kevin in April 2025. The large sedge perched on the log was happily sitting just above the water for years. It is now suspended nearly a metre above the water, gaining sustenance from the drying mud. Will it outlive the dry spell?

Leaving rainfall deficits to one side, a more telling indication of the state of things is the grazing pressure. Our macropod numbers are up, owing to the good conditions from 2020-23, providing ample food to raise young. While we fence and net our vegetable garden from their depredations, the culinary herbs have been unprotected for 16 years, and never touched. Until this month. But now I know the palatability of all our herbs by the order in which they have been progressively defoliated by roos and wallabies. They like mint best, then tarragon, sage, oregano, marjoram, and have yet to demolish the thyme. I am hoping they do not develop a taste for these and will leave them alone when their normal forage returns.

On the positive side, our landscape is still vaguely green, owing to the unpalatable, stress-tolerant ground covers – Lomandra spp., Dianella, Carex appressa. Together with the hayed-off perennial grasses, these plants have continued to provide good cover, and will protect the soil when the next deluge arrives.

Even cheerier, are the shrub species, which are happily pushing out modest numbers of flowers, against all odds. The Urn Heath (Melichrus urceolatus) is the commonest of this group in our area, much loved by honeyeaters and rosellas.

Although it purportedly likes damp soil, the Small-fruited Hakea, (Hakea microcarpa) is flowering now.

Other local species that are currently attracting Eastern Spinebills and White-eared Honeyeaters on Gang Gang are Hakea microcarpa, Grevillea lanigera and Banksia marginata. Some of you may also have Peach Heath (Lissanthe strigosa). Not only do these plants provide a nectar source for birds, flowering also benefits insects, and the birds that feed on insects.

While the death of the pea shrubs seems ominous, I am confident that these short-lived low-growing shrubs (e.g. Pultenaea, Dillwynia, Bossiaea, and Daviesia) will regenerate well from seed when suitable rainfall arrives. Some decent falls will revive humans and nature alike.

Bowning Bookham Landcare, in partnership with Local Land Services, recently hosted a hands-on Small Scale Erosion Control Workshop in Bowning. The workshop attracted local landholders keen to learn more about managing and slowing erosion on their properties using practical, low-cost methods.

Throughout the day, participants gained a better understanding of the different types of erosion and the land management practices that can contribute to it. Discussions covered ways to minimise erosion, such as strategic fencing, grazing, and establishing or managing vegetation to protect soil and water resources.

The workshop also showcased a range of erosion control structures, from hay bales, jute mesh and coir logs used to slow runoff or redirect water, through to small rock ramps and how to build them effectively. These simple, affordable techniques were demonstrated on-site, offering participants a clear sense of what’s possible with the right tools and planning.

A key focus was on assessing a site to determine why erosion is occurring, what sort of interventions might work, and where they should be placed. The use of swales—either above or below problem areas—was explored as a practical design feature to help manage water flow and reduce soil loss.

By the end of the session, participants walked away with greater confidence and a suite of ideas they could apply on their own properties to address small-scale erosion concerns.
