The Dry - It's Hurting

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.

 

Blog Dam

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.

 

Blog Hakea

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.

Practical Solutions for Erosion: Landholders Build Skills in Bowning

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.

Weeds Beware! Sutton Landcare Springs into Action at the Reserve

It was a beautiful Sunday morning when 9 people gathered at the Sutton Reserve behind the school. Recognised as a valuable original native box gum woodland It Is under attack by weeds, and we are trying to improve it for the first time in 30 years or so.

 

The Sutton Landcare Group now has permission from Crown Lands to start work like weeding and cleaning up. It was a very successful morning: in one and a half hours we removed:  

130 serrated tussock

30 Briar rose

20 Cotoneasters

10 Scotch Thistles

A red myrtle

50 St Johns Worts

200 Sifton bushes

20 Hawthorn

25 small Grevilleas (these grevilleas are garden escapees. The larger ones will be left for small birds, but we will try to stop them from spreading too much and taking over from other natives)

and 3 large bags of litter (Thank you, Dave O’Sullivan for taking care of those).

The rest of the serrated tussock and the large blackberries will be tackled later (too much to remove by hand).

It was amazing to see how much can be done by an enthusiastic group of people.  We all learnt from each other: recognising weeds, ways to manage them, freeing up native plants etc.

 

If you live near the Reserve, or you would like to help Sutton Landcare to make the Reserve a true community asset, with paths and seating, please roll up your sleeves and join us the next time!

Genetic Diversity in Our Seeds: Are We on the Right Track?

Sourcing seed from a wide range of provenances is a core part of YAN’s Climate Ready Revegetation project. Through our partnership with the Botanic Gardens Sydney, we now have the opportunity to assess whether seed from diverse provenances is delivering the genetic diversity we aim to achieve.

 

Over the next three years, we will sample three plant species grown from our carefully sourced Climate Ready seed, starting with Yellow Box (Eucalyptus melliodora).

 

On Thursday, 27 March, YAN’s Climate Ready Team welcomed special visitors Marlien van der Merwe and Tricia Hogbin from the Botanic Gardens of Sydney’s Research Centre for Ecosystem Resilience, along with Michelle Dawson from AdaptNSW, to the Murrumbateman Landcare Nursery.

We presented Marlien and Tricia with 12 seed collections of Eucalyptus melliodora, which their team will germinate and sample for genetic analysis. Marlien and Tricia then showed us how to take leaf samples from our nursery plants before heading out to two of our Climate Ready trial sites. There, we collected additional leaf samples from planted-out Yellow Box, as well as some beautiful old remnant trees.

We were grateful to catch up again with Michelle, as she and her AdaptNSW team have provided invaluable support and advice to our project over the last seven years.

To top off the science, we enjoyed a shared meal, featuring delicious home-grown produce from some of our wonderful trial hosts.

 

We can’t wait to learn about the results from the genetic testing!
