Home is Where the Hollow is

Tree hollows and fallen logs provide important homes for Australian wildlife, but they’re disappearing at an alarming rate. Trees are essential for native wildlife to find food, shelter and places to roost and nest. Hollow-bearing tees are especially important because many species use these hollows daily and seasonally to nest and raise their young.

 

In New South Wales, at least 174 animal species rely on tree hollows, including 46 mammals species, 81 bird species, 31 reptile species, 16 frog and countless invertebrates. Of these species, 40 are threatened and availability of hollow-bearing trees is crucial for their survival.

Tree hollows take hundreds of years to form but are quickly disappearing due to human activities like land clearing. They are not easily replaced. However we have the opportunity to act and make a difference.

 

Watch: ‘Home is where the Hollow is’

 

Let’s work together to protect the homes of the wildlife we love - how you can help;

  • - Keep and protect all trees with hollows, even if they are dead.
  • - Allow native vegetation to regrow and regenerate.
  • - Leave fallen logs and debris on the ground.
  • - Learn about the importance of tree hollows as homes and share this knowledge with your neighbours and community.
  • - Consider installing nest boxes as a last resort if there are very few natural hollows.
  • - Think twice about firewood collection. Make sure firewood is sustainably sourced.

Big Questions, Rich Insights: Highlights from Murrumbateman Landcare’s July Q&A Session

Murrumbateman Landcare Group’s recent July Q&A session drew a large and engaged audience – including a strong contingent from the Bowning Bookham Landcare group. With questions submitted ahead of time and a great panel of local experts – Jacqui Stol, Sue McIntyre, and Dave Jarrett (Weeds Officer with Yass Valley Council) – the event sparked a lively and informative conversation that stretched well beyond the scheduled time.

 

After the formal session, participants stayed on to mingle over drinks and nibbles, sharing ideas and swapping stories. It was clear that the appetite for practical knowledge and peer-to-peer learning remains strong across our region.

The session tackled eight wide-ranging questions – each deserving of a full workshop in itself – covering everything from ecosystems and weeds, to revegetation and the effects of climate change. Here are just a few highlights:

 

Ecosystem Types in the Southern Tablelands

The Q&A began with an overview of the region’s ecosystems, highlighting the critical conservation value of what remains. Less than 30% of the original Box Gum Grassy Woodlands still exist in the Southern Tablelands – a nationally significant figure given that just 5% remains intact across Australia. Meanwhile, about 50% of the original dry sclerophyll forest is still present, although the ground layer is now heavily modified.

 

One key takeaway: areas where forest and woodland species mix – the ecotones – tend to be particularly species-rich and are ideal for conservation efforts. Maintaining structural diversity, including patches of bare ground, is also important for supporting different plant species, although this may sometimes conflict with weed control or erosion management.

 

Designing Effective Windbreaks

Another practical discussion revolved around shelterbelt design. Rather than blocking wind entirely, the goal should be to slow it down by creating windbreaks with plants at varying heights. This helps avoid the creation of wind tunnels and reduces stress on pastures and stock.

 

Importantly, the panel advised against planting exotic conifers like Leyland Cypress, which can become problematic. Instead, landholders were encouraged to consult resources like Sustainable Farms’ Shelterbelt Guide and consider native alternatives, such as Callitris (native cypress pine).

 

Weed Management – What’s Changed?

Dave Jarrett provided valuable updates on weed legislation and local priorities. The term “noxious weed” is no longer used, and there is now a focus on “priority weeds”, with different levels of management required depending on their risk.

 

At the state level, weeds like Parthenium (sometimes found in organic chicken feed) must be eradicated immediately. Regional priority weeds, such as Hawkweed, are also targeted early. At the local level, problem plants include:

  • - Serrated Tussock – seeds remain viable for up to 15 years; effective spraying requires treating the whole plant, not just the edge. Think of it as “a bunch of spring onions” – with many individual shoots bundled together.
  • - Coolatai Grass, Sticky Nightshade, African Lovegrass, St John’s Wort, and Chilean Needle Grass were also flagged.

Protecting Native Forbs from Grazing

A question about protecting small native plants from grazing prompted some creative strategies. Jacqui shared that she sometimes chases kangaroos away at dusk to give recovering areas a break from pressure – though more systematic approaches were also discussed like maintaining fallen timber and rocks, ecological burns and grazing managment .

 

Climate Resilience in Revegetation

Finally, the panel tackled one of the biggest questions of all: how can we prepare for projected climate change when planning revegetation?

 

Key points included:

  • - Use Climate Ready plants from local YAN nurseries
  • - Choose sites carefully, considering soil fertility and grazing pressure
  • - In some cases, soil scalping may be useful to suppress exotic competition
  • - And remember: revegetation outcomes are always shaped by climate, grazing, and site conditions

Reliable Water for a Greener Yass: Yass Landcare Nursery Gets Town Water Access

We’re thrilled to share some wonderful news for the Yass Landcare Nursery and the broader Yass community. After many years relying solely on limited tank water, the Yass Landcare Nursery has now been granted access to town water, with water bills waived, thanks to the recent support of Yass Valley Council.

 

This change marks a huge step forward for the nursery, which produces 3,000–4,000 native plants each year for revegetation projects across the district. Until now, the dedicated team of volunteers who run the nursery have had to make do with rainwater collected from tanks. During dry periods, this often wasn’t enough to keep plants alive and healthy, limiting the nursery’s ability to meet demand and support local environmental restoration efforts.

Access to town water—used only when absolutely essential, means that our volunteers can continue growing a healthy and diverse range of native plants year-round, even in times of drought. This ensures we can keep supporting revegetation, habitat restoration, and other projects both big and small across the Yass Valley.

The announcement was celebrated this week with a visit to the nursery by The Hon. Ron Hoenig MP Minister for Local Govenrment,  The Hon. Wendy Tuckerman MP Member for Goulburn, and Mayor Jasmin Jones. The visit was a valuable opportunity to showcase the nursery’s role in the community and discuss the infrastructure and support needed to keep this special place thriving. One practical issue identified during the visit was the need to repair the community centre guttering, which will improve the efficiency of rainwater collection for the tanks.

The recent Council decision to waive water bills and allow essential use of town water can be found in the July 24 Council meeting agenda (Item 8.6), a strong demonstration of Council’s support for grassroots environmental community groups.

 

We’d like to say a huge thank you to all of our incredible volunteers, whose ongoing care, advocacy, and commitment have made this possible. Your hard work and persistence are helping to grow a greener, healthier Yass Valley—literally.

 

Want to get involved?

We’re always looking for more hands to help. Join us for our regular nursery working bees on the second and fourth Saturday of each month, or come along to our National Tree Day celebration on Saturday 26 July, where we’ll be planting around the nursery grounds.

Supporting Our Local Birdlife: Highlights from the Bird Life Pest and Threats Workshop

A perfect sunny winter’s afternoon brought together a group of keen landholders for the BirdLife Pest and Threats Workshop, eager to learn how to better support the birdlife in our region. A healthy bird population is a sign of a biodiverse, resilient landscape — and there are plenty of practical ways we can all help.

The silent threat of rodenticides

Shirali Dave from BirdLife Australia highlighted the devastating impact of second-generation rodenticides — products like RatSak and Talon — on native predators such as owls, eagles, falcons and quolls. These poisons accumulate in the bodies of rodents, which are then eaten by native wildlife, leading to secondary poisoning and death.

 

PestThreats 3   PestThreats 1

 

The good news? Safer alternatives exist. Traditional traps, newer electric traps, and first-generation rodenticides that work faster (and break down quicker) all reduce the risk to wildlife. You can read more about these options here.

 

Want to take action? Write to your Minister and email your council to help get dangerous rodenticides out of our community.

Noisy miners, cats, and other challenges

Paul Russell from BirdLife Australia explored how native (but pest) species like the noisy miner are impacting woodland birds. These aggressive birds thrive in open, nectar-rich landscapes, chasing off smaller species.

Paul’s advice?

  • Plant dense, spiky mid-storey shrubs to provide shelter for small birds.
  • Choose native species with smaller flowers (like correas, small grevilleas, and hakeas) to discourage noisy miners.

Paul also spoke about the toll cats — both feral and domestic,  take on native wildlife. Pet owners can help by keeping cats in enclosed runs. Advocating for cat containment and curfews at a local level is another positive step.

Protection, food and nesting material plants

 

Foxes: a shared challenge

Leah Samson from Gunning District Landcare painted a sobering picture of fox populations in our region — an estimated 4.7 foxes per square kilometre around Yass. Foxes prey on native species and livestock and are difficult for any one landholder to control. 

The message was clear: landholders working together through coordinated programs like the integrated pest management initiative ‘Feral Fighters’ can reduce the populations of foxes and other feral animals. By coordinating the management of feral pests such as foxes, pigs, rabbits across neighbours landholders can make a real difference. If your area doesn’t yet have a feral control program, now’s the time to connect with your neighbours, Landcare group, or Local Land Services team.

Mess is best!

To wrap up the afternoon, Alison Elvin led participants on a guided walk, showcasing habitat features that support birdlife. From fallen logs and rocks to rough grasses and dense shrubs — all these messy bits of the landscape provide shelter, food, nesting materials and even medicines for birds.
