If you’ve passed by Sutton Reserve recently, you may have noticed some changes. Volunteers from Sutton Landcare and the Sutton and District Community Association (SDCA) have been hard at work improving the reserve so it can become a real asset for both the village and the wider region.

This work follows the Sutton Reserve Masterplan, adopted by both community organisations and supported by Crown Lands, which manages the reserve. The plan sets out a long-term vision for the area – but before new features like walking paths, yarning circles, and information signs can be created, we first need to tackle a major challenge: removing invasive trees, shrubs, and weeds.

Why remove pine trees and other non-natives?

Not all trees are good for the reserve. Some non-native species, such as radiata pines, Cootamundra wattles, sifton bush, and hawthorns, spread aggressively and outcompete the native plants and old eucalypts that should be thriving here. Large pines in particular “throttle” established gums, depriving them of water, nutrients, and space. Left unchecked, these species threaten the biodiversity of the reserve and reduce the habitat available for native birds, insects, and reptiles.

Over the past six months, volunteers have achieved a huge amount, removing:

• - 385 sifton bush
• - 10 Cootamundra wattles
• - 45 escapee grevilleas
• - 30 young pines
• - 45 briar roses
• - 25 hawthorns
• - 140 serrated tussocks
• - 150 St John’s Wort plants
• - Plus 5 x 50 L bags of litter

All cuttings without seed have been left on the ground, where they help create habitat for ground-dwelling insects, reptiles, and small birds.

Supported and collaborative work

This work is being done with environmental works permission from Crown Lands, with additional support from Yass Valley Council through targeted weed spraying. Looking ahead, there are plans (pending approvals) for:

• - Removing some larger pines impacting old eucalypts
• - Healing or cool burns
• - Further St John’s Wort control by professionals
• - A rabbit eradication program this summer with Local Land Services

Looking to the future

The long-term vision is for Sutton Reserve to become a welcoming, accessible space for the whole community. Future plans include:

• - Walking paths
• - Yarning circles
• - Information signs about local biodiversity
• - Improved fencing and access

Get involved

A huge thank you goes out to all the volunteers who have already given their time – their efforts have made a real dent in the weed problem. It's been great to meet some of the locals who are keen to lend a hand and get involved in the care and restoration of this wonderful community asset.

The next working bee will be held on Saturday 12 October at 9:30 am. These are gentle, social activities where people can do as much or as little as they feel comfortable with – even just coming along to learn about weeds and native plants is welcome. Membership of Landcare is optional and not required.

On Science Week Sunday, Yass Landcare joined forces with Wildlife Reimaginations to bring a day of hands-on, nature-inspired activities to Coronation Park, Yass. Around 250 people — from curious toddlers to wise octogenarians — wandered through the stalls and activities, each taking away something new.

The event was a perfect pairing of wildlife exploration and Landcare, sparking conversations about our natural environment and the many ways we can care for it. Visitors of all ages were enthralled, and the buzz around the park made it clear: this is something we’d love to make an annual tradition.

Creative, Colourful Science

Children and adults alike got stuck into vegetable scrap dyeing.  Learning how to turn everyday kitchen leftovers into vibrant inks and patterns. There was smashing, squishing, and stamping with mallets and chopping boards as colour revealed itself on paper and fabric. The joy on children’s faces was priceless as colours shifted, dyes emerged, and food scraps took on a new life in their artistic creations.

Playing with Acidity and Alkalinity

Budding soil scientists explored the pH of everyday household products and discovered how this affects plant growth. Visitors dug through real soil samples to find organic matter, root filaments, and the tiniest of creatures with various invertebrates. One slater almost found itself adopted as a pet by an enthusiastic young participant! It was a tactile, eye-opening way to learn how soil health supports plant life.

Understanding Compost and Food Waste

A compost activity demonstrated the gasses released by decomposing food scraps, showing exactly why it’s better to feed them to the garden rather than send them to landfill. The bubbling, fizzing, and lively discussions made for a memorable lesson in waste reduction and soil enrichment.

A Big Thank You

Events like these don’t happen without our community. A huge thank you to the volunteers who designed, set up, and ran the activities, giving their Sunday to share knowledge, enthusiasm, and a love natural sciences. With so much curiosity sparked and so many smiles shared, it’s safe to say this was a Science Week event which everyone enjoyed.

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.

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
