We have continued to imple- ment our Strategic Plan to integrate science into the delivery of the Department’s strategic goals of wildlife management, parks management, forest management, and managed use of natural assets. Our resources and activities are aligned with our core functions to ensure we are delivering best practice science driven by management priorities to inform effective conservation. Through 2015-16 we continued our work in the core areas of conserving threatened plant, animals and communities, landscape scale conservation, wildlife assets and inventory, WA Herbarium, bushfire research, marine monitoring and research, forest monitoring and research, wetland monitoring, hydrological monitoring, and data management and distribution. Some highlights of activities this year have been the launch of books documenting the outcomes of the Kimberley Islands Survey and the Pilbara Biological Survey; development of a Population Viability Analysis for Carnaby’s cockatoo; knowledge to support recovery actions for threatened animals, birds and plants affected by the severe fires along the south coast in 2015; establishing a survey database to ensure effective management of plot based data; review of the marine monitoring program to direct resources to the most effective outcomes and rationalise the reporting framework; and reconstruction of the major fires affecting WA in the past twelve months. Support for Biodiversity and Marine Science as one of the State Government’s five science priorities contin- ues. The Western Australian Biodiversity Science Institute (WABSI) was launched by the Premier in October 2015 as a joint venture between nine founding partners, including the Department of Parks and Wildlife. The Governing council and Board are guiding its establishment, with an Executive Director in place and two Node Leaders appointed for the Biodiversity Survey, and Biodiversity Processes and Threats Nodes. Node Leaders for the Information Management, and Restoration and Ex-situ Conservation Nodes are being sought. I look forward to engagement of the Division in all of the nodes as the institute develops and with all relevant partners in delivering the agreed research plan for each node. Our partnership with WAMSI continues and many projects under the Kimberley Marine Research program are now in the knowledge exchange phase. A series of seminars and meetings with managers and end-users were delivered to help understand the implications of the research outputs for marine park management. It is pleasing to see major engagement of divisional staff with three hubs of the National Environmental Science Program (NESP), the Threatened Species Hub, the Northern Australian Environmental Resources Hub and the Marine Science Hub. The NESP hubs are strongly aligned with our own objectives as they seek to deliver applied research to support on-ground management; hence the involvement of our staff provides a key perspective on the application of excellent science to address conservation and management issues. This year has seen a national focus on threatened species following the Threatened Species Summit where the Threatened Species Commissioner released the Threatened Species Strategy. Many of the target species for the strategy are found in Western Australia and our research on the biology and ecology of these species and their threats is critical to making a difference in conservation management outcomes. Many of our scientists were involved in the Threatened Species Forum coordinated by the Northern Agricultural Catchment Council and held in Geraldton to highlight the conservation management of threatened species in Western Australia. As we continue to deliver excellent science to underpin effective biodiversity conservation in Western Aus- tralia, I encourage you all to make the most of opportunities and continue to seek innovative ways of delivering science to support the Department’s core functions. I welcome our continued engagement with all our partners, both within the Department and externally, in the delivery of innovative science to inform conservation and management of our plants, animals and ecosystems, and to support effective management of our parks and reserves, delivery of our fire program, managed use of our natural resources and science stories that inspire and engage people to embrace our natural heritage.

Acacia longifolia is an aggressive invader worldwide. This species was brought to Portugal by the forestry services and is now found throughout the country with very strong ecological and social impacts. Al- though several ecological and physiological studies have been carried out, molecular studies in this species are sparse. Particularly, genetic variability evaluation in invasive ranges clearly deserves more attention. The aim of this study was to evaluate the genetic diversity and the genetic differentiation among populations of the alien in- vasive A. longifolia under different Mediterranean conditions. For that we studied three sandy dune populations along the Portuguese coast: Osso da Baleia (mesomediterranean), Pinheiro da Cruz and Vila Nova de Milfontes (termomediterranean). All sampled acacia plants were located underneath a pine forest, with the exception of the latter case study, where we also sampled in a diversified habitat conditions associated with the margins of agriculture fields.

This brief report presents the results obtained during that field work. Scope and Objectives The potential development site (defined by the boundaries of the study area) around the Brockman Camps extends over an area of 180 ha, of which 53 ha has been cleared or is deemed as extensively disturbed. Prior to this clearing, a survey conducted by Biota in early December 2006 and late January 2007 recorded no flora of conservation significance in this area (Biota 2007). Vegetation over about 30 ha of the remaining area was previously mapped as part of the Brockman Syncline 4 (BS4) project (Biota 2006). The botanical field survey was therefore conducted over the remaining 97 ha of the study area (adjoining the previously surveyed BS4 study area). This survey was undertaken in accordance with the Guidance Statement No. 51 "Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia" (EPA 2004).

Bremer Range N Gibson & M N Lyons Science and Information Division, Department of Conservation and Land Management, Wildlife Research Centre, PO Box 51 Wanneroo WA 6065 email: [email protected]; [email protected] Manuscript received March 1997; accepted November 1997 Abstract A study of the flora and plant communities of the Bremer Range greenstone belt in the spring of 1994 recorded 267 taxa. Only eight weed species were recorded but this number is likely to increase if further work is carried out in a better season. The flora list included one species gazetted as rare and new populations of five rare or poorly known taxa. Three species appear to be endemic to the Bremer Range greenstone belt, one of which was collected for the first time. Six community types were defined from 64 sites spread across the range. The distribution of these community types appears to be primarily controlled by edaphic factors including soil water holding capacity. The floristic classification is in broad agreement with previous work but shows finer-scale patterning. None of the floristic communities or the endemic taxa are presently reserved. There has been significant impact on the vegetation of this range by mining and mineral exploration. Introduction time (possibly Cretaceous) of higher rainfall.
