Note This plan was prepared by the Department of Environment and Conservation (DEC), which on 1 July 2013 separated to become the Department of Parks and Wildlife, and the Department of Environment Regulation. While the Department of Parks and Wildlife printed this plan in July 2013, actions outlined were already underway by the then DEC. This document develops and explains important issues that would otherwise need significant diversions in the Drummond Natural Diversity Recovery Catchment recovery plan 2011–2031. Some of these appendices are effectively drafts or working papers which have been developed as part of the plan preparation, or are snapshots of existing information. As such they should not be viewed as official documents or up-to-date publications. They are designed to provide access to background information and provide details of published references.

Recovery catchments will contain very high nature conservation values at risk. Assessment of catchments will involve the following attributes: • how representative the catchment biota is of important natural communities • presence of threatened communities and species • species and community richness • whether the catchment provides an important biological corridor (e.g. connecting Lake Magenta Nature Reserve and Fitzgerald River National Park), or other significant ecological service • international or national significance of the area (e.g. Ramsar Convention, Directory of Important Wetlands in Australia). Biogeographic representation It is desirable to have recovery catchments that represent a range of situations. For example, as many IBRA regions as practicable will be represented, consistent with other criteria. Opportunities for research and Research and development or demonstration sites, particularly those with state or development or demonstration national or international significance, might include special management techniques sites for: • nature conservation • farm economics • cultural change or improved social interaction • landcare. Tenure of land at risk While conservation lands that are the focus of recovery catchments for natural diversity should be vested with the Conservation Commission of Western Australia, other land tenures may be considered for selection as recovery catchments if they are sufficiently important for nature conservation and threatened by salinity. Representation of hazard The greater the hazard to an important site, the greater the urgency for action. However, recovery catchments will be selected that represent a range of hazard situations including those that are threatened in the longer term by salinity, but are at present in good condition. Potential for success In the main, catchments will be selected that are likely to lead to success. This will involve, for example, taking into consideration: • ‘physics’ of pressure (e.g. is hydrological pressure overwhelming?) • area of catchment (bigger catchments are generally more difficult to recover) • degree of threat • level of landcare community support, knowledge and enthusiasm • potential to use prospective commercial species in revegetation • current area and distribution of remnant vegetation (the more the better). Socio-political considerations There will be demands from a plethora of socio-political stakeholder groups ranging from catchment groups to federal agencies and politicians. The demands from these groups will need to be taken into consideration. 3 Appendix 2 Nomination document for the Drummond Natural Diversity Recovery Catchment This document is a reproduction of the original To the east and downstream from Drummond Nature nomination document produced by the former Reserve, the Solomon Creek Catchment flattens containing Department of Conservation and Land Management heavier loam, or gravel, over clay duplex soil with isolated in 2001.

Hertweck Dr. J. Chris Pires, Dissertation Advisor JULY 2011 The undersigned, appointed by the dean of the Graduate School, have examined the dissertation entitled GENOME EVOLUTION IN MONOCOTS Presented by Kate L. Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

  • Powerful Pollinators Encouraging Insect Pollinators in Farm Landscapes
    Bilpin, Blue Mountains: NSW Powerful pollinators Encouraging insect pollinators in farm landscapes Pollinators are an essential component of agricultural production and of healthy, biodiverse landscapes. Protecting and enhancing pollinator resources on farms will help support a diverse range of pollinators. This brochure provides an introduction to encouraging insect pollinators on farms, including a guide to choosing plants that will support diverse pollinators throughout the year. The power of pollinators Pollinators – mostly insects, but also birds and mammals – assist the formation of seeds and fruit in many plant species by visiting flowers in search of food (nectar and/or pollen). Whilst foraging they transfer pollen from one flower to another, facilitating fertilization, which results in fruits and seeds. Honey bees, native bees and other native insects like hoverflies, wasps and butterflies provide essential © Amy-Marie Gilpin pollination services for native plants, Native vegetation supports pollinators by providing food and nesting sites. Nearby crops and garden flowers, fruits and vegetables. pastures will benefit from the increased abundance and diversity of pollinators in the landscape.

  • Inselbergs) As Centers of Diversity for Desiccation-Tolerant Vascular Plants
    Plant Ecology 151: 19–28, 2000. 19 © 2000 Kluwer Academic Publishers. Printed in the Netherlands. Dedicated to Prof. Dr Karl Eduard Linsenmair (Universität Würzburg) on the occasion of his 60th birthday. Granitic and gneissic outcrops (inselbergs) as centers of diversity for desiccation-tolerant vascular plants Stefan Porembski1 & Wilhelm Barthlott2 1Universität Rostock, Institut für Biodiversitätsforschung, Allgemeine und Spezielle Botanik, Rostock, Germany (E-mail: [email protected]); 2Botanisches Institut der Universität, Bonn, Germany (E-mail: [email protected]) Key words: Afrotrilepis, Borya, Desiccation tolerance, Granitic outcrops, Myrothamnus, Poikilohydry, Resurrection plants, Velloziaceae, Water stress Abstract Although desiccation tolerance is common in non-vascular plants, this adaptive trait is very rare in vascular plants. Desiccation-tolerant vascular plants occur particularly on rock outcrops in the tropics and to a lesser extent in temperate zones. They are found from sea level up to 2800 m. The diversity of desiccation-tolerant species as mea- sured by number of species is highest in East Africa, Madagascar and Brazil, where granitic and gneissic outcrops, or inselbergs, are their main habitat. Inselbergs frequently occur as isolated monoliths characterized by extreme environmental conditions (i.e., edaphic dryness, high degrees of insolation). On tropical inselbergs, desiccation- tolerant monocotyledons (i.e., Cyperaceae and Velloziaceae) dominate in mat-like communities which cover even steep slopes. Mat-forming desiccation-tolerant species may attain considerable age (hundreds of years) and size (several m in height, for pseudostemmed species). Both homoiochlorophyllous and poikilochlorophyllous species occur. In their natural habitats, both groups survive dry periods of several months and regain their photosynthetic activity within a few days after rainfall.

  • Combined Phylogenetic Analyses Reveal Interfamilial Relationships and Patterns of floral Evolution in the Eudicot Order Fabales

We combine published molecular data for the chloroplast regions matK and rbcL with 66 morphological characters surveyed for 73 ingroup and two outgroup species, and use Parsimony and Bayesian approaches to explore matrices with different missing data. All combined analyses using Parsimony recovered the topology Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). Bayesian analyses with matched morphological and molecular sampling recover the same topology, but analyses based on other data recover a different Bayesian topology: ((Polygalaceae + Leguminosae) (Quillajaceae + Surianaceae)). We explore the evolution of floral characters in the context of the more consistent topology: Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). This reveals synapomorphies for (Leguminosae (Quillajaceae + Suri- anaceae)) as the presence of free filaments and marginal ⁄ ventral placentation, for (Quillajaceae + Surianaceae) as pentamery and apocarpy, and for Leguminosae the presence of an abaxial median sepal and unicarpellate gynoecium. An octamerous androecium is synapomorphic for Polygalaceae. The development of papilionate flowers, and the evolutionary context in which these phenotypes appeared in Leguminosae and Polygalaceae, shows that the morphologies are convergent rather than synapomorphic within Fabales.

  • Phylogeny and Phylogenetic Nomenclature of the Campanulidae Based on an Expanded Sample of Genes and Taxa

A. 3 Author for correspondence ( [email protected] ) Communicating Editor: Javier Francisco-Ortega Abstract— Previous attempts to resolve relationships among the primary lineages of Campanulidae (e.g. Apiales, Asterales, Dipsacales) have mostly been unconvincing, and the placement of a number of smaller groups (e.g. Bruniaceae, Columelliaceae, Escalloniaceae) remains uncertain. Here we build on a recent analysis of an incomplete data set that was assembled from the literature for a set of 50 campanulid taxa. To this data set we first added newly generated DNA sequence data for the same set of genes and taxa. Second, we sequenced three additional cpDNA coding regions (ca. 8,000 bp) for the same set of 50 campanulid taxa. Finally, we assembled the most comprehensive sample of cam- panulid diversity to date, including ca. 17,000 bp of cpDNA for 122 campanulid taxa and five outgroups. Simply filling in missing data in the 50-taxon data set (rendering it 94% complete) resulted in a topology that was similar to earlier studies, but with little additional resolution or confidence.

  • Pollination Ecology of Trachymene Incisa (Apiaceae
    CHAPTER 1 INTRODUCTION Photograph: newly opened Trachymene incisa umbel Introduction 1-2 For each pollinator bee is in fact a little cupid that creates hot romances between plants thought to be stupid. Each bee can be considered a matchmaking agency that arranges introductions for a nominal nectar fee. From “Cupid” by Paul D. Haemig, http://www.ecology.info/cupid.html POLLINATION ECOLOGY Mutualistic interactions are among the most widespread interactions in nature, but also the least well understood compared to other interactions such as predation (Ollerton 2006). Mutualisms are relationships between species that result in reciprocal benefits. Biotic pollination, the transfer of pollen by animals from the anther to the stigma of flowers, is a mostly mutualistic interaction (see Renner 2006 for exceptions), with pollinators usually receiving pollen and/or nectar from plants in return for their pollinating service. Animal pollinators have been important since the angiosperms evolved, with evidence indicating that early members of the angiosperms were insect pollinated (Crane et al. 1995). Over 91% of the 240 000 angiosperm species worldwide are animal-pollinated (Buchmann and Nabhan 1996), distributed throughout approximately 93% of angiosperm genera (Renner and Ricklefs 1995). With vertebrates pollinating only 0.51% of species, insects are responsible for pollinating over 90% of angiosperm species (Buchmann and Nabhan 1996). The four largest orders of insects, Coleoptera, Hymenoptera, Lepidoptera and Diptera, include species that are known to pollinate flowering plants (Proctor et al. 1996). The total number of pollinator species is unknown, although estimates vary between 130 000 and Introduction 1-3 300 000 (Shepherd et al.
