Biodiversity

The Macedon Ranges is an epicentre for low-lying Snow Gums in Victoria (Eucalyptus pauciflora) and they occur in several ecosystems and geology types throughout the shire.

There has been recent community concern of dieback identified in Snow Gum populations on Mount Macedon and surrounds and climate modelling indicates this vegetation type is the most vulnerable to climate change.

We have been working with ecologists, Landcare Groups, the community and the Arthur Rylah Institute to record and monitor the health of Snow Gum populations across the shire and potential local climate change impacts.

The results of the Snow Gum Monitoring Survey have now been compiled into a detailed report(PDF, 8MB).

Clover Glycine – Citizen Science Success

On the 29 October, 10 citizen scientists turned out to continue the Clover Glycine investigation survey at Bald Hill and Black Hill Reserves. 

Two surveys were completed at Bald Hill and Black Hill Reserve in areas adjacent to known populations. The surveys resulted in 143 new plants at 4 new locations in Bald Hill Reserve. At Black Hill Reserve, 14 new plants in a known location and 8 plants across 4 new locations, totalling 22 new plants.

The finds at Black Hill are significant as two locations are adjacent to the ridge track which has experienced storm damage and requires repair. Knowing these locations will inform future works to ensure their protection as well as guide future survey efforts.

Precious Peas

In October 2021, Gardening Australia aired a story where Millie Ross joined Martin Roberts, our Bushland Reserves Officer at Bald Hill Reserve, Kyneton. At 95 hectares of grassy woodland, Bald Hill reserve is the largest in the shire, and one of the most precious. Clover Glycine is a good indicator species for the health of the wider ecosystem in these reserves.

The episode aired during series 32, episode 29. View the recording at Gardening Australia. 

Largest population of Clover Glycine ever recorded found at Bald Hill Reserve - November 2020

Bald Hill Reserve recently reinforced its value as a significant conservation asset with the surveying of the largest Clover Glycine population ever recorded.

The Friends of Bald Hill Reserve and Council completed an extensive survey for this nationally threatened native pea species as part of the delivery of a Commonwealth Communities Environment Program grant. The species was known to exist at the site and had contributed to Council’s decision to acquire the land and establish it as a conservation reserve 30 years ago.

The survey recorded 1,343 specimens at the reserve which is the largest population ever recorded. Surveys were also conducted at Black Hill Reserve where four specimens were found. The species is also known to occur on private properties in the area.

A diversity of native peas is essential to the health of many ecosystems as they provide essential nutrients to support the growth of other plants. 

The Macedon Ranges Shire contains many different ecosystems that are characterised by different types of plants and animals. These ecosystems include woodlands, grasslands, forests and wetlands. Each ecosystem is classified according to ecological vegetation classes (EVC).  In the Macedon Ranges, twelve EVCs are 'endangered', nine are 'vulnerable', four are 'depleted' and six are of 'least concern'.

Further information about EVCs in Macedon Ranges can be found on our page native plants.

Forests

The Macedon Ranges contains a range of wet, damp and dry forests which are critical to Victoria's biodiversity and support our ecosystems by helping to purify our water, stabilise our soil, retain nutrients and absorb carbon emissions. These forests support a diversity of rare and threatened flora and fauna species such as the Common Spider Orchid, Dwarf Silver Wattle, Brush-tailed Phascogale, Powerful Owl, Barking Owl, Greater Glider and Brown Treecreeper.

Woodlands

Much of the Macedon Ranges was originally a temperate woodland. Today, only fragments of this original ecosystem exists, particularly on hilly sites where soils were often less nutrient rich compared to the flat pasture areas.   

A woodland is an area of widely spaced trees where the canopy of trees don't touch. They have trees that rarely exceed 30 metres in height, and grassy ground cover. These significant ecosystems have been extensively modified since European settlement for farming.

A healthy woodland is made up of multiple vegetation layers which include a tree canopy cover, an under storey of shrubs, grassy cover and a ground layer of litter. All of these layers act as a system that provides shelter and food for native species of wildlife.

Ground cover such as old logs, rocks, fallen trees and leaf litter are associated with highly diverse areas of woodland. A woodland environment that looks messy is often a healthy system.  Fallen timber provides ideal habitat for a range of insects which provide other local native fauna such as Sugar Gliders with ample food. Native reptiles also use ground litter such as fallen logs and rocks to shelter from weather and to lay eggs under.

Grasslands

Grasslands are fragile ecosystems that usually have few or no trees. Although grassland plants are generally small, they can create colourful mosaics, especially in springtime when wildflowers are blooming. Grasslands and grassy woodlands once covered about a third of Victoria. Today less than 0.1% is left. Grasslands support a range of rate or threatened plants, birds and reptiles that are in danger of extinction. A few scattered patches of grassland and grassy woodland vegetation remain in Macedon Ranges, mainly in the south of the shire.

Council approved the Biodiversity Strategy at its 19 December 2018 Council Meeting. The strategy identifies policy and planning initiatives, as well as priorities for protection, community engagement and processes for monitoring biodiversity. 

The strategy's objectives are to:

• protect existing biodiversity and native vegetation
• improve existing biodiversity and native vegetation across public and private land
• increase the extent of native vegetation cover for connectivity
• improve Council and the community's understanding and connection to biodiversity
• enhance the capacity of community groups to undertake conservation activities
• develop a shire-wide biodiversity monitoring program that assesses the health of the broader ecosystem.

At is Ordinary Meeting on 27 October 2021, Council adopted a refreshed version of the Environment Strategy, updated from its first Environment Strategy of June 2016. It outlines future directions and key actions for the themes:

• Climate Emergency
• Biodiversity
• Water
• Waste.

Council publishes an Annual Environment Report to summarise progress on implementation of the Strategy,  according to stated indicators for each theme.
