The Planning Team prepared the plan for the Conservation Commission of Western Australia. Brendan Dooley (Plan Coordinator) Department of Conservation and Land Management Tim Bowra Department of Conservation and Land Management Dennis Cluning City of Joondalup Phil Thompson City of Wanneroo PREFACE Regional parks are areas of regional open space that are identified by planning procedures as having outstanding conservation, landscape and recreation values. Regional parks provide the opportunity for a consortium of management agencies and private landowners to develop co-ordinated planning and management strategies. Regional parks were first proposed in the Stephenson - Hepburn Report of 1955, which later formed the basis of the Perth Metropolitan Region Scheme in 1963. Since then, State planning agencies have been acquiring suitable private land in anticipation of the time when regional parks would be formally created. In 1997, the State government announced a commitment to introduce legislation to give regional parks legal standing and vesting in the former NPNCA, now the Conservation Commission of Western Australia. Eight regional parks were recognised as formal identities, with the co-ordination of their management progressively transferred to the Department of Conservation and Land Management.

  • Volatiles Associated with Different Flower Stages and Leaves of Acacia
    South African Journal of Botany 76 (2010) 701–709 www.elsevier.com/locate/sajb Volatiles associated with different flower stages and leaves of Acacia cyclops and their potential role as host attractants for Dasineura dielsi (Diptera: Cecidomyiidae) ⁎ M.J. Kotze a, , A. Jürgens b, S.D. Johnson b, J.H. Hoffmann a a Zoology Department, University of Cape Town, Rondebosch 7701, South Africa b School of Biological and Conservation Sciences, University of KwaZulu-Natal Pietermaritzburg, Private Bag X01, Scottsville 3209, South Africa Received 19 June 2010; received in revised form 26 July 2010; accepted 27 July 2010 Abstract Acacia cyclops (Fabaceae) is an Australian species which was introduced into South Africa in the nineteenth century. Because of its invasive status in South Africa, a gall midge, Dasineura dielsi (Diptera: Cecidomyiidae), was released in 2001 in order to impact its reproduction by inducing galls on the flowers and thereby preventing seed set. Nothing is known about the cues used by D. dielsi for locating its host flowers. As part of an initial investigation into whether or not chemical cues might play a role in host finding, we analysed headspace samples of Acacia cyclops volatiles from leaves and reproductive parts at different stages (early bud, late bud, early flowering, and senescing flowering stages) using gas chromatography–mass spectrometry (GC–MS). In total, 72 different compounds were detected of which 62 were identified. The analyses showed that open flowers, the stage used by D. dielsi for oviposition, and yellow buds had similar odour compositions with (Z)-3-hexen-1-ol acetate, 4-oxoisophorone, (Z)-β-ocimene, an unknown aliphatic compound, heptadecane, and nonadecane dominating in open flowers.

  • Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt
    plants Article Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt Rania A. Hassan * and Rim S. Hamdy Botany and Microbiology Department, Faculty of Science, Cairo University, Giza 12613, Egypt; [email protected] * Correspondence: [email protected] Abstract: For the first time, an updated checklist of Acacia, Senegalia and Vachellia species in Egypt is provided, focusing on the exotic species. Taking into consideration the retypification of genus Acacia ratified at the Melbourne International Botanical Congress (IBC, 2011), a process of reclassification has taken place worldwide in recent years. The review of Acacia and its segregates in Egypt became necessary in light of the available information cited in classical works during the last century. In Egypt, various taxa formerly placed in Acacia s.l., have been transferred to Acacia s.s., Acaciella, Senegalia, Parasenegalia and Vachellia. The present study is a contribution towards clarifying the nomenclatural status of all recorded species of Acacia and its segregate genera. This study recorded 144 taxa (125 species and 19 infraspecific taxa). Only 14 taxa (four species and 10 infraspecific taxa) are indigenous to Egypt (included now under Senegalia and Vachellia). The other 130 taxa had been introduced to Egypt during the last century. Out of the 130 taxa, 79 taxa have been recorded in literature. The focus of this study is the remaining 51 exotic taxa that have been traced as living species in Egyptian gardens or as herbarium specimens in Egyptian herbaria. The studied exotic taxa are accommodated under Acacia s.s. (24 taxa), Senegalia (14 taxa) and Vachellia (13 taxa).

Bredenkamp November 2003 © University of Pretoria The works of the LORD are great, Studied by all who have a pleasure in them. Psalm 111 : 2 (NKJV) Dedicated to my parents ABSTRACT Phytosociological study of Andrew's field and Tsaba-Tsaba nature reserve, . Bredasdorp district, Western Cape. by MARGARETHA MARIA ZIETSMAN Supervisor: Prof. Dr. G.J. Bredenkamp DEPARTMENT OF BOTANY UNIVERSITY OF PRETORIA MAGISTER SCIENTIAE The vegetation of Andrew's Field and Tsaba-Tsaba nature reserve, Bredasdorp district, Western Cape was hierarchical classified using Braun-Blanquet procedures and TWINSPAN. The resulting 10 plant communities, 19 sub-communities and four variants, were described and ecological interpreted. The vegetation was sampled using 171 randomly stratified sample plots. The floristic composition, Braun-Blanquet cover-abundance scale of each species, and various environmental variables were recorded in each sample plot. The relation between the vegetation units and the associated environmental gradients was confirmed by DECORANA ordination, conducted on the floristic data. The conservation priority of each vegetation unit was determined by taking Red Data List species, limestone endemic species and Cape Floristic Region endemic species into consideration. The distribution of the vegetation units can mainly be ascribed to differences in the clay/sand content of the soil and the degree of exposure of the vegetation to the dominating winds (Southeastern and Northwestern) of the area.

  • December 2009 Monthly Report
    March 2012 MONTHLY REPORT Compliance Management Roland and Stefan checked 39 recreational fishing and bait collectors permits during March. Of the 39 permits checked 5 did not have valid permits on them and were given friendly warnings. There were no fines issued this month however all three rangers attended a peace officers course at the Goukamma Marine Protected Area. The peace officers course was held on the 27th, 28th and 29th and presented by Dr. FJW Herbig. As it currently stands, the rangers cannot issue any J534 fines as they do not have those powers. If the rangers encounter any serious offences, Dept. of Fisheries has to be contacted in Mossel Bay to come out and write the necessary fines. This often takes a while, complicating the fining process. Once the rangers have received their certificates, they need to apply to be appointed as peace officers by the Station Commander at the nearest Police Station. They then need to approach Dept. of Fisheries to be appointed as Fisheries Control Officers, that can enforce the Marine Living Resources Act. Once this has been completed the rangers will have the powers to fine people on the spot for any contraventions of the Marine Living Resources Act. On the 30th, the rangers attended a one day self defense course. The instructor focused on key elements during a confrontational situation and how one can deal with them in the best manner. A big thank you to Wayne Meyer (Ex Fransmanshoek Senior Ranger), who now works at Goukamma Marine Protected Area, for organizing both short courses mainly for the Cape Nature staff but managed to slot the Fransmanshoek Conservancy rangers in the program.
