This lot (referred to herein as ‘the site’) is located approximately 18 kilometres (km) south of the Perth Central Business District within the City of Melville. An ecologist from Emerge Associates visited the site on 24 June 2019 and undertook a ‘level 1’ fauna survey and a targeted black cockatoo survey. During the survey targeted searches for fauna species were conducted with a particular reference for ‘threatened’ and ‘priority’ fauna species and an assessment was made on the type and conservation significance of fauna habitat across the site.

  • Quenda Wetland Reserve Strategic Management Plan
    City of Melville Quenda Wetland Reserve Strategic Management Plan 08 August 2016 Executive Summary Quenda Wetland Reserve is a wetland reserve located within the City of Melville, in the suburb of Murdoch. The wetland is a conservation category sumpland with a man-made lake to collect extra stormwater runoff from surrounding development areas. Quenda Wetland Reserve is part of a regionally significant wetland and bushland ecological linkage that connects to other reserves throughout the Swan Coastal Plain region. These conservation values justify the need for a site-specific strategic management plan prepared in accordance with the Natural Areas Asset Management Plan (Waters A., 2011). The reserve consists of dryland and wetland vegetation that has intact vegetation structure, with minor disturbances present and floristic community types are considered well reserved and at low risk (Government of Western Australia, 2000). In addition to the open water body, the reserve has four distinct vegetation types as determined by Ecoscape (2015), namely: . Dry Shrubland . Melaleuca preissiana Woodland . Sedgeland . Wet Shrubland. Two species listed as at-risk by the City were recorded on site by Ecoscape (2015), including: . Low priority species – Hibbertia cuneiformis, which is considered to be dubious and not naturally occurring in the site . Very High priority species – Grevillea obtusifolia, which is at risk of being lost form this reserve and is poorly represented on the Swan Coastal Plain. Quenda Wetland Reserve provides habitat for several threatened or priority fauna species in decline on the Swan Coastal Plain, including: . Forest Red-tailed Cockatoos (Calyptorhynchus banksii naso), . Southern Brown Bandicoot or Quenda (Isoodon obesulus fusciventer) .

  • Environmental Assessment Report (EAR) (Current Document) for the DP
    Department Of Communities - Housing Environmental Assessment for Davis Park March 2019 Executive summary The Department of Communities – Housing (Housing) has assembled a project team, with Urbis being the lead town planning consultant, to prepare for the lodgement and approval of the Davis Park Local Structure Plan (DPLSP). The aim of the DLSP is to guide the future development of the Davis Park (DP). The DP is located along major arterial roads and within 3 km of Fremantle CBD and 20 km of Perth CBD. GHD Pty Ltd (GHD) was commissioned by Housing to provide an environmental assessment report (EAR) (current document) for the DP. The EAR includes a desktop and vegetation assessment of the project area to identify environmental constraints and native vegetation on site. This information will be used to assist in the design process. It is GHD’s understanding that this EAR will be included in the DPLSP report. This report is subject to, and must be read in conjunction with, the limitations set out in section 1.6 and the assumptions and qualifications contained throughout the Report. Key findings Desktop assessment The project area is located on the Spearwood Dunes landform system and consists of brown and yellow sands of varying depths over limestone. The project area slopes in an east to west direction towards Bruce Lee Reserve. No Local Water Management Strategies or Stormwater drainage studies were available for the study area. Broad scale pre-European vegetation mapping revealed one vegetation association within the project area: Jarrah, marri and wandoo Eucalyptus marginata, Corymbia calophylla, E. wandoo (association 998).

BLAIR HEDGES Department of Biology, Pennsylvania State University, 208 Mueller Lab, University Park, PA 16802, USA. E-mail: [email protected] Abstract Skinks are usually grouped in a single family, Scincidae (1,579 species) representing one-quarter of all lizard species. Oth- er large lizard families, such as Gekkonidae (s.l.) and Iguanidae (s.l.), have been partitioned into multiple families in recent years, based mainly on evidence from molecular phylogenies. Subfamilies and informal suprageneric groups have been used for skinks, defined by morphological traits and supported increasingly by molecular phylogenies. Recently, a seven- family classification for skinks was proposed to replace that largely informal classification, create more manageable taxa, and faciliate systematic research on skinks. Those families are Acontidae (26 sp.), Egerniidae (58 sp.), Eugongylidae (418 sp.), Lygosomidae (52 sp.), Mabuyidae (190 sp.), Sphenomorphidae (546 sp.), and Scincidae (273 sp.). Representatives of 125 (84%) of the 154 genera of skinks are available in the public sequence databases and have been placed in molecular phylogenies that support the recognition of these families. However, two other molecular clades with species that have long been considered distinctive morphologically belong to two new families described here, Ristellidae fam. nov. (14 sp.) and Ateuchosauridae fam. nov.
