EXECUTIVE SUMMARY Brett Lane and Associates Pty Ltd were commissioned to undertake a flora, fauna and net gain assessment of a property located at 135 O’Herns Road, Epping. The investigation was undertaken to investigate the extent and quality of native vegetation and fauna habitat on the subject land in view of the proposed development. One moderate to highly degraded patch of remnant native vegetation comprising Stony Knoll Shrubland of high conservation significance (according to Victoria’s Native Vegetation Management Framework) was identified and assessed in the study area. Any proposed removal of this native vegetation would require a permit from the local planning authority. Approved native vegetation removal would attract an Offset obligation under the Net Gain policy and DSE guidelines. Should the removal of 0.03 hectares of Very High Conservation Significance Stony Knoll Shrubland (as found in Habitat Zone C) be sought, a net gain target of 0.024 habitat hectares would be required to be achieved. This gain would need to be achieved through the management, for conservation purposes, of Stony Knoll Shrubland elsewhere in the Victoria Volcanic Plain bioregion. The development plan must demonstrate how impacts on Habitat Zone C have been avoided and minimised in accordance with Victoria’s Native Vegetation Management Framework. Removal of this patch of Stony Knoll Shrubland will require the approval of the Minister (or his delegate). No state or nationally listed flora or fauna species of conservation significance were detected during the field survey undertaken for this assessment. No species of flora listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 are considered to potentially occur in the study area. However, Purple Diuris, listed under the state Flora and Fauna Guarantee Act 1988, has the potential to occur in the remnant patch of Stony Knoll Shrubland. There is a low potential for the nationally and state threatened Golden Sun Moth to be present in the Stony Knoll Shrubland (Habitat Zone C) within the study area. A targeted survey

  • Coliban Water Castlemaine Link - Sandhurst Reservoir Alignment Options Flora and Fauna Assessment August 2016
    Coliban Water Castlemaine Link - Sandhurst Reservoir Alignment Options Flora and Fauna Assessment August 2016 Executive summary The Castlemaine Link Harcourt Modernisation Project is a three-stage project. This report relates to a portion of Stage 2, the Castlemaine Link Project (the project), which consists of 13 km of pipe and is in the approvals phase. In 2011 Biosis conducted a flora and fauna assessment of the original alignment through the Sandhurst Reservoir area. The original alignment is no longer a viable option as a number of assets have been built over the proposed construction corridor since the original assessments were undertaken in 2011. As such, Coliban Water has developed two alternative pipeline alignment options within the Sandhurst Reservoir area. The purpose of this report is to identify the ecological values and constraints associated with the two alternative alignment options within the Sandhurst Reservoir area, to identify ways to avoid and minimise impacts to native vegetation and fauna habitat, and to determine the legislative implications that may arise for the two alignments, compared to the implications for the original alignment. WTP Alignment Summary Impacts on vegetation in the WTP Alignment would be limited to planted indigenous and non-indigenous vegetation as well as a small patch of native regrowth (0.04 ha) where the WTP Alignment is that of the original alignment (see section 4.1.1 for details). Proposed impacts to vegetation along the WTP Alignment are unlikely to require assessment under the Biodiversity Assessment Guidelines, and will not require additional permits, approvals or vegetation offsets. It is estimated that the WTP Alignment would have approximately the same impact on native vegetation as the original alignment.

Biodiversity Action Planning Strategic Overview for the Central Victorian Uplands Bioregion Victoria March 2003 . Biodiversity Action Planning - Strategic Overview for the Central Victorian Uplands Bioregion. March 2003. Executive summary 1. This Biodiversity Action Plan for the Central Victorian Uplands translates the Victorian Biodiversity Strategy (NRE 1997) in a regional context, and provides the foundation for producing landscape- scale biodiversity action plans to direct on-ground works by private landholders, community groups, corporations and all levels of Government, with the ultimate aim of achieving broad-scale conservation of biodiversity assets across the bioregion. 2. The Central Victorian Uplands covers 1.2 million hectares extending over 21 local government areas and seven Catchment Management Authorities, stretching from the Grampians and Ararat in the west, to Porepunkah in the east, and from Lurg in the north, to the You Yangs and Lara in the south. It has a unique and relatively early history of European settlement due to the gold rushes in nearby regions in the 1850’s and soldier settlements after World War I and II. The settlers of the gold rush period and soldier settlements were quick to recognize the productive potential of the Central Victorian Uplands’ woodlands and dry grassy forest complexes and, consequently, the landscape has been radically and rapidly changed within the last 150 years. 3. Seventy-eight percent of the region is private freehold dominated by agriculture and there are large blocks of public land including several major national Parks and State Forests. Native vegetation covers 29% of the Central Victorian Uplands and 8.5% of this is occurs in formal reserves.

Kuiter1 and Mitchell J. Findlater-Smith2 1Aquatic Photographics, Seaford, Victoria. 2Woolenook Native Plant Nursery, Maffra, Victoria. Correspondence: [email protected] Abstract Members of the large terrestrial orchid-genus Pterostylis, collectively known as greenhoods and rustyhoods, attracted only insects of the order Diptera, the flies, as their principal or primary vectors. With few exceptions, the pollinator species were part of the superfamily Sciaroidea: infraorder Bibionomorpha: families: Mycetophilidae and Sciaridae, that are commonly known as fungus-gnats and dark-winged fungus-gnats respectively. Introduction All information provided is based exclusively on our additional scent. Several small greenhoods taxa, extensive observations. Only species that proved to that lack long lateral-sepals, apparently produce a be convincing pollinators were included as principal food-suggesting scent, which is probably emitted or primary vectors. Identification was limited to the primarily from this lure. Taxa with a fully exposed genus level, primarily based on their wing-venation, labellum emit kairomones, that are produced most using European taxonomy (sciaroidea.info). Taxa strongly from the basal mound. identified as vectors were assigned a number within each genus for reference purposes. Observations The principal Greenhood pollinators were made on sites during conditions when insects All medium to large hooded taxa were pollinated by were expected to be active, and by watching a Mycetophilidae fungus-gnats.
