1. Background

The Department of Infrastructure, Energy and Resources (DIER) is responsible for the management of a large area of land incorporated in its roadside reserve system. Roadside reserves vary due to factors including their shape and size, variety of users and impacts, tenure and primary use as a transport corridor. To the untrained eye, these areas may appear quite degraded and unimportant. They are easy places for weeds and other pests to establish, spreading either naturally or unintentionally through normal maintenance activities.

However many of DIER's roadsides contain patches of remnant vegetation that present valuable populations of rare and threatened plant species; priorityvegetation communities; corridors for wildlife movement; wildlife habitat; andold growth/heritage trees. Concentrations of threatened species located within agricultural landscapes are often an important relic of pre-European vegetation.

DIER is obliged to protect and conserve plant and animal species listed under state and federal legislation as threatened species or critical habitat.

These species are protected by law - fines apply for damaging them!!

This website outlines a new program established by DIER's Roads and Public Transport Division to prevent and minimise impacts upon threatened species' the Conservation Sites Program.

Conservation Sites Program

The goal of the Conservation Sites Program is to prevent or minimize the likelihood of damage to high priority threatened species and threatened species habitat.

To achieve this, the program is guided by a management plan that has been approved by DPIWE under the Threatened Species Act.

Features of the program include:

  • Greening Australia's threatened species markers installed at key locations
  • annual training in the use of the marker system
  • 'Enviromark' specifications outlining management requirements at each site
  • annual monitoring and reporting regime between DIER and DPIWE
  • support and sponsorship for on-ground works associated with managing the identified sites.

2. The Legal Side of Things

Roadside sites that support threatened species are significant and protected under State and Federal legislation. DIER has an obligation to actively manage the natural values of roadsides, to anticipate threatening processes and apply measures to prevent or minimize the likelihood of damage to biodiversity.

In accordance with the Threatened Species Protection Act 1995, DIER and DPIWE have developed a Public Authority Management Agreement (PAMA) to protect high priority threatened species and critical habitat. The PAMA provides agreement upon the management practices to be conducted to conserve and protect threatened species for particular areas.

Detailed management activities for each site are documented in the key document attached to the Agreement - Conservation Sites Management Plan for High Priority Botanical Sites.

3. Where are they?

There are over 400 roadside sites that support threatened species across the State road network.There are well-documented concentrations of threatened species sites in the Midlands and parts of the East Coast.

A number of critical species and critical habitats have been identified as being a priority for pro-active management in the State roadside reserve network (North Barker 2000).These occur where roadside populations are important to the conservation of the species, where the adjacent vegetation has been destroyed or is vulnerable to farming practices.

The Conservation Sites Management Plan describes management activities for forty three (43) conservation sites that are either 'critical plant species sites' or 'critical threatened species habitats'.

Tables of these sites, cna be viewed as either GDA94 (GPS) or chainage.

Management of these sites will encompass the management of all known populations of two threatened species, and the main population of another.

4. What is out there and what are they?

The critical threatened flora species (or groups of species) that DIER is pro-actively managing under the Conservation sites program are:

Conservation Sites Project Management Category
Sites 1-2 Orchids (Prasophyllum apoxychilum, Prasophyllum concinnum, Thelymitra jonesii)
Sites 3 Viminaria juncea
Sites 4 Eucalyptus morrisbyi
Sites 5-9 Lepidium hyssopifolium
Sites 10-14 Austrodanthonia popinensis

The grassland and grassy woodland habitats that have been identified as critical and included in this current plan are:

Conservation Sites Project Management Category
Sites 15-23 Tunbridge Grasslands
Sites 24-25 Holyman Avenue Grasslands
Sites 26-29 Wanstead Grassland
Sites 30-38 Avoca Grasslands
Sites 39-43 Lake Leake Junction - Tasman Highway

5. Markers and Specifications
Greening Australia's Enviromark system

Unintentional damage or degradation to significant vegetation or habitat areas may not be apparent to the untrained eye immediately, however over time can lead to the loss of species from an area and changes to ecosystems.

A lack of awareness that an area is important or lack of knowledge of a high priority sites exact location can lead to unintentional damage or degradation. This damage or degradation can lead to penalties under the Threatened Species Protection Act 1995.

By clearly marking the location of these sites and describing how activities are to be performed within the area, activities will have less impact upon environmental values.

Greening Australia has developed a series of markers called 'Enviromark'. These markers have been installed at the start and end of each of the Conservation Sites in this program.

The management regime within each site is clearly documented in an Enviromark Specification for each site.The Conservation Sites are generally the area from the back of the table drain to the fence boundary, not including any areas maintained for road safety.

Specifications provide site-specific instructions on mowing/slashing; drain clearing; scraping/grading; removal of material; stockpiles and parking; pruning; clearing, digging and construction; weeding; and machines and equipment.
