Charles Darwin Reserve (White Wells Station), Western Australia – Field Herbarium 1 BACKGROUND AND ACKNOWLEDGEMENTS Over two weekends in 2008, volunteers from the Wildflower Society of Western Australia (WSWA) Bushland Plant Survey Group visited the Bush Heritage Australia property Charles Darwin Reserve (previously known as White Wells Station). The purpose of the visits was to survey several areas of the Reserve, in order to provide a species list and field herbarium to complement existing floristic and vegetation information for the Reserve. Three previsits conducted during the year prior to the main surveys also contributed to the results. It was decided to conduct two surveys, one early in spring and one later, so that plants and habitats that flower at different times would be sampled. For example, granite areas flower early but are finished by the time the sandplain comes into flower. The first main survey was held on 22nd -25th August 2008, and was hosted by locum managers Len and Valerie Warren. Twenty-six participants established twenty-one 20 m x 20 m quadrats (A1-A6, B1-B5, C1-C5, D1-D5; see Map 1), both north and south of the homestead. Data was recorded by groups of volunteers led by a botanist or experienced volunteer. The second survey was held on 10 th – 13 th October 2008, and was hosted by managers Kurt and Andrea Tschirner. Twenty-three participants established a further thirteen 20 m x 20 m quadrats (W1-W4, X1-X5, Y1-Y4; see Map 2), revisited some of the August quadrats and made several opportunistic collections, including around the homestead. The purpose of the revisits was to collect further material of any plants that were not yet in flower in August (eg. grasses). Opportunistic collections were conducted to collect good flowering material for herbarium specimens, especially of plants that might not have been recorded in quadrats. The season for the surveys was good with sufficient rains for spectacular shows of flowers (including annuals) in most areas, especially the granites. Thank you to the recent managers of the Reserve, Kurt and Andrea Tschirner (and Geri and baby Maia) without whose whole-hearted support the surveys could not have taken place. The help and enthusiasm of the Wildflower Society volunteers and botanists and Friends of Charles Darwin Reserve were vital and they all gave generously of their time (over 4,500 volunteer hours for the surveys and post-survey processing). Participants in the previsits and surveys were Logan Anderson, Anne and Alan Bellman, Arthur Blundell, Kate Brown, Ross Cockerell, Geoff Corrick, Margaret Corrick, Hazel Dempster, Janet and Barry Dufall, Helen and Keld Frederiksen, Elizabeth George, Ann Gunness, Rosemary Harper, Bronwen and Greg Keighery, Margaret and Jeff Langley, Margaret Larke, Kristina, Arie, Aidan and Ella Lemson, Vanda Longman, Nina McLaren, Diane and Gary Matthews, Brian Moyle, Dorothy Perret, Phylis Robertson, Marta Rossignoli, Tracy Scott, Nina Stick, Alice Stubber, Lorraine Todd, Margaret Tyrka, Len and Valerie Warren, Pat Wenham and Mary Yates. The work at the Western Australian Herbarium, including plant sorting and identification, compiling the field herbarium, entering data on Max, compiling species lists and mounting, labelling and scanning the specimens, was carried out by Anne Bellman, Arthur Blundell, Geoff Corrick, Hazel Dempster, Elizabeth George, Ann Gunness, Rosemary Harper, Cyril Kelly, Georgina Lambert, Margaret Larke, Kristina Lemson, Melissa and Vanda Longman, Brian Moyle, Sue Pedrick, Dorothy Perret, Phylis Robertson, Alice Stubber, Pat Wenham and Mary Yates. Plant identifications were verified at the Western Australian Herbarium with assistance from the following specialists: Russell Barrett, Rob Davis, Malcolm French, Alex George, Elizabeth George, Mike Hislop, Bruce Maslin, Barbara Rye, Kelly Shepherd, Malcolm Trudgen, Carol Wilkins and Paul Wilson. The project relied on weekly sessions at the Western Australian Herbarium, using its facilities. The support of the Herbarium is gratefully acknowledged. A big thank you to all the Herbarium staff who have been involved in various ways in our project.

For more information about the project and its results, see the full report (Wildflower Society of Western Australia 2010). 3 THE FIELD HERBARIUM A field herbarium is useful for a number of reasons: • it allows easy identification of many local species • it can encourage people to learn more about their local bushland • it is a lasting record of the plant species found in the survey. 3.1 Organisation of the Field Herbarium The Charles Darwin Reserve field herbarium specimens have been pressed, dried and identified, mounted on stiff A4 cards, labelled, inserted in plastic sleeves and stored in 24 A4 lever arch files. The specimens have been arranged alphabetically in plant families and within families alphabetically by genera. Grasses, rushes, sedges and sedge-like herbs have been grouped together in one file; they have similar life forms and it was considered this would make identification easier for users. The weeds have been grouped alone in another file as it is considered important to any bushland management to be able to distinguish between a native plant and an introduced plant. Because of high visitation to Charles Darwin Reserve it was felt a reference set of species growing close to the homestead would be a useful resource for the visitor’s quarters. So a collection of specimens from the area around the homestead was made. A separate little field herbarium with colour scans of specimens has been made as a useful and durable ready reference for visitors. Each specimen in the field herbarium has been scanned and is available electronically in the accompanying

  • Vegetation of Durokoppin and Kodj Kodjin Nature Reserves
    II VEGETATION OF DUROKOPPIN AND KODJ KODJIN NATURE RESERVES B.G. MUIR INTRODUCfION Durokoppin Reserve (DR) and Kodj Kodjin Reserve (KKR) both fall within the Avon district of the South-west Botanical Province of Gardner and Bennetts (1956) and the vegetation of the Reserves largely conforms to that generally found throughout this region. Abbreviated vegetation descriptions of DR appear in Appendix 1 and of KKR in Appendix 3. Full descriptions of the vegetation following the format presented in Muir (1977a) have been lodged in the Archives of Western Australian Museum; details are available on request from the Librarian. A description of the road verge connecting DR and KKR is given at the end of Appendix 1. Methodology The vegetation of DR and KKR was mapped at Level 2 of the reliability scale set out in Muir (1977a). Each vegetation formation discernible on the air photographs was examined on the ground; this information was then extrapolated to adjacent formations. Uncleared land contiguous to the Reserves but not included within them was mapped at formation level directly from the photographs (Level 3). Level 2 locations, shown on vegetation Maps 1 and 2 represent 'sample areas' where the vegetation was examined and described using the classifica­ tion shown in Table 1 and discussed in detail in Muir (1977a). The following prefix numbers of the locations represent basic formation types. 1 woodland formations 5 lithic complexes 2 mallee formations 6 breakaway complexes 3 shrubland formations 7 salt complexes 4 heaths 8 other Level 3 locations are shown on the maps prefixed by: W = woodland formations M = mallee formations The methods used in classifying formations, coding habitat data, preparing plant lists, classifying litter and describing soils are those of Muir (1977a).

  • FINAL REPORT 2019 Canna Reserve
    FINAL REPORT 2019 Canna Reserve This project was supported by NACC NRM and the Shire of Morawa through funding from the Australian Government’s National Landcare Program Canna Reserve BioBlitz 2019 Weaving and wonder in the wilderness! The weather may have been hot and dry, but that didn’t stop everyone having fun and learning about the rich biodiversity and conservation value of the wonderful Canna Reserve during the highly successful 2019 BioBlitz. On the 14 - 15 September 2019, NACC NRM together with support from Department of Biodiversity Conservation and Attractions and the Shire of Morawa, hosted their third BioBlitz at the Canna Reserve in the Shire of Morawa. Fifty professional biologists and citizen scientists attended the event with people travelling from near and far including Morawa, Perenjori, Geraldton and Perth. After an introduction and Acknowledgement of Country from organisers Jessica Stingemore and Jarna Kendle, the BioBlitz kicked off with participants separating into four teams and heading out to explore Canna Reserve with the goal of identifying as many plants, birds, invertebrates, and vertebrates as possible in a 24 hr period. David Knowles of Spineless Wonders led the invertebrate survey with assistance from, OAM recipient Allen Sundholm, Jenny Borger of Jenny Borger Botanical Consultancy led the plant team, BirdLife Midwest member Alice Bishop guided the bird survey team and David Pongracz from Department of Biodiversity Conservation and Attractions ran the vertebrate surveys with assistance from volunteer Corin Desmond. The BioBlitz got off to a great start identifying 80 plant species during the first survey with many more species to come and even a new orchid find for the reserve.

There were plenty of Awww’s as Kathryn showed us her humble beginnings in the garden as she recalled many hours helping her dad as she was growing up. Kathryn continued her love of gardening, formalising it by obtaining a Bachelor of Design and Master of Landscape Architecture at RMIT, although she admitted that it was a course about the ‘feelings’ of plants, and not actually about plants themselves. Her hard work paid off as she was part of a team that won a Gold Medal at the Grand Designs Live Exhibition in 2012 for their structure incorporating succulents.

    DRAFT 25/10/90; plant list updated Oct. 1992; notes added June 2021. PRELIMINARY REPORT ON THE CONSERVATION VALUES OF OPEN COUNTRY PADDOCK, BOOLARDY STATION Allan H. Burbidge and J.K. Rolfe INTRODUCTION Boolardy Station is situated about 150 km north of Yalgoo and 140 km west-north-west of Cue, in the Shire of Murchison, Western Australia. Open Country Paddock (about 16 000 ha) is in the south-east corner of the station, at 27o05'S, 116o50'E. The most prominent named feature is Coolamooka Hill, near the eastern boundary of the paddock. There are no conservation reserves in this region, although there are some small reserves set aside for various other purposes. Previous biological data for the station consist of broad scale vegetation mapping and land system mapping. Beard (1976) mapped the entire Murchison region at 1: 1 000 000. The Open Country Paddock area was mapped as supporting mulga woodlands and shrublands. More detailed mapping of land system units for rangeland assessment purposes has been carried out more recently at a scale of 1: 40 000 (Payne and Curry in prep.). Seven land systems were identified in open Country Paddock (Fig. 1). Apart from these studies, no detailed biological survey work appears to have been done in the area. Open Country Paddock has been only lightly grazed by domestic stock because of the presence of Kite-leaf Poison (Gastrolobium laytonii) and a lack of fresh water. Because of this and the generally good condition of the paddock and presence of a wide range of plant species, P.J.

  • 1 a Survey of the Flora of Remnants Within the Waddy
    1 A SURVEY OF THE FLORA OF REMNANTS WITHIN THE WADDY FOREST LAND CONSERVATION DISTRICT Stephen Davies and Phil Ladd for the Waddy Forest Land Conservation District Committee March 2000 2 CONTENTS INTRODUCTION 1 METHODS 3 RESULTS 4 DISCUSSION 56 ACKNOWLEDGEMENTS 59 REFERENCES 60 Appendix 1 - Composite plant list 60 Appendix 2 - Plants found outside the sample sites 67 Appendix 3 - Composite bird list 67 3 INTRODUCTION The Waddy Forest Land Conservation District is about 41,000 hectares and contains 23 substantial land holdings. In 1999 the District received a grant from the National Heritage Trust to survey the flora of its remnant vegetation. Much of this is on private property and the District Committee selected thirty three plots of remnant bushland on private farms to be included in flora survey. The present report is based on visits to these thirty three remnants that lie on 14 of the 23 farms in the district. The surveys are intended to provide information about the biodiversity of the various remnants with the aim of establishing the priority for preservation, by fencing, of the remnants and to determine the value of linking some of them by the planting of corridors of vegetation. At each site the local landholder(s) joined the survey and provided invaluable background information about the history of the remnants. The vegetation of this part of the northern wheatbelt is known to be very diverse. The Marchagee Nature Reserve, lying north west of the District, was surveyed between 1975 and 1977 (Dell et al. 1979). The area was covered by Beard in his vegetation mapping project (Beard 1976), and part of the south of the District was covered in a report on Koobabbie Farm in 1990 (Davies 1990).

In this study, the spatial and temporal dynamics of the bacterial communities associated with grapevine organs (leaves, flowers, grapes, and roots) and soils were characterized over two growing seasons to determine the influence of vine cul- tivar, edaphic parameters, vine developmental stage (dormancy, flowering, preharvest), and vineyard. Belowground bacterial communities differed significantly from those aboveground, and yet the communities associated with leaves, flowers, and grapes shared a greater proportion of taxa with soil communities than with each other, suggesting that soil may serve as a bacterial res- ervoir.
