CALM Land Information Branch 11 FOREWORD Western Australian Wildlife Management Programs are a series of publications produced by the Department of Conservation and Land Management (CALM). The programs are prepared in addition to Regional Management Plans to provide detailed information and guidance for the management and protection of certain exploited or threatened species (e.g. Kangaroos, Noisy Scrub-bird and the Rose Mallee). This program provides a brief description of the appearance, distribution, habitat and conservation status of flora declared as rare under the Western Australian Wildlife Conservation Act (Threatened Flora) and poorly known flora (Priority Flora) in CALM's Geraldton District and makes recommendations for research and management action necessary to ensure their continued survival. By ranking the Declared Rare Flora in priority order for these requirements, Departmental staff and resources can be allocated to taxa most urgently in need of attention. Priority Flora that are under consideration for declaration are also dealt with, but to a lesser extent than the Declared Rare Flora. The information available should assist in the ongoing work of assessment of their conservation status. This Program has been approved by the Executive Director, Department of Conservation and Land Management, the Conservation Commission and the Minister for the Environment. Approved programs are subject to modification as dictated by new findings, changes in species' status and completion of recovery actions. Information in the Plan was accurate at August 1998. iii TABLE OF CONTENTS Page Page Foreword .......................................................... iii Menke a draboides ............................................. 72 Phlegmatospermum drummondii ...................... 74 Acknowledgements ......................................... viii Plectrachne bromoides ..................................... 76 Pterostylis sp.

  • 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.

  • Assessment of Dalwallinu Shire Wattles Considered Prospective for Human Food
    Assessment of Dalwallinu Shire Wattles considered prospective for human food A Report Produced For The Shire of Dalwallinu By Bruce Maslin and Jordan Reid December 2008 1 2 Assessment of Dalwallinu Shire Wattles considered prospective for human food By Bruce Maslin & Jordan Reid Western Australian Herbarium, Department of Environment and Conservation, Kensington, W.A. Preamble Following a request from Mr Robert Nixon, President of the Dalwallinu Shire Council, and a meeting with Shire Councillors McFarlane, Carter, Dinnie and Sanderson, CEO Crispin and Brent Parkinson, we undertook a quick assessment of the Acacia flora of the Dalwallinu Shire with a view to identifying those species that might have potential for cultivation as a source of commercial quantities of seed for human consumption. The work was conducted between 2-5 December 2008. Introduction There are about 80 different Acacia (Wattle) species that occur in the Shire of Dalwallinu. Ten of these species were included in Edible Wattle Seeds of Southern Australia (Maslin et al. 1998) as having some potential for development as new crop plants as a source of seed for human consumption. From the outset it is recommended that readers familiarize themselves with Maslin et al. (1998) and Simpson & Chudleigh (2001) because these two works provide much valuable information relevant to the domestication of Acacia as human food crop in low rainfall areas. Little or no attempt has been made here to reproduce the information contained in these works (we have simply focused on identifying those species in the Dalwallinu Shire that we consider as prospective for development as new seed crops).

  • 10 Seed Release and Dispersal Mechanisms
    10 Seed Release and Dispersal Mechanisms For seedling recruitment to occur seeds need to be dispersed into an environment that promotes germination and seedling survival. Dispersal consists of two phases. Primary dispersal is defined as the initial transport of seeds or seed-bearing fruits (collectively seeds and fruits are called diaspores) to the ground or water body, or for aerial parasites, a host branch. Secondary dispersal relates to any subsequent movement to the seed’s final resting place. Primary dispersal may be active (e.g. seeds released explosively from the fruit, e.g. dehiscence (opening) of Hardenbergia pods), passive (e.g. seeds fall out when the capsules of Eucalyptus open), or require a vector to aid in seed removal (e.g. wind uplift of winged seeds of Hakea or winged fruits of Nuytsia; Amyema berries consumed by mistletoe birds). Secondary dispersal involves either a biotic (e.g. ants) or environmental (e.g. wind, water) vector, and it is usually a different mechanism than that involved in primary dispersal. While primary dispersal is usually only for a few metres, secondary dispersal may cover several kilometres, and sometimes thousands for tiny seeds. This chapter covers some of the dispersal mechanisms exhibited by the SouthWest flora following their release. Terminology used to describe seed dispersal mechanisms is provided in Table 10.1. Table 10.1: Seed dispersal terminology. Term Definition Anemochory Wind dispersed Chamaechory Dispersal by rolling along the ground (wind assisted) Zoochory Animal dispersed (general) Myrmecochory Ant dispersed Ornithochory Bird dispersed Mammalochory Mammal dispersed Hydrochory Water dispersed Barochory Unassisted (gravity causes seeds to drop to the ground) Autochory Dispersal assisted by the actions of the parent plant (e.g.

Facultad de Estudios Superiores Iztacala, Universidad Nacional Autónoma de México, Tlalnepantla, Estado de México, México. 2 Departamento de Ecología Evolutiva, Instituto de Ecología, Universidad Nacional Autónoma de México, CDMX, México. Author for correspondence: [email protected] Abstract Background: The Neotropical ant-acacias show morphological variations in their vegetative characteristics as a consequence of their relation- ship with ants. However, there is no information regarding whether floral organs have also undergone any modification that prevents resident ants from approaching the inflorescences in anthesis. Questions: Are the patterns of floral development affected by the relationship with ants? Is there any floral organ or structure involved in avoid- ing the presence of ants during the flowering period? At what stage of development do these modifications arise, if at all? Studied species: Acacia cornigera (L.) Willd. Study site: Santiago Pinotepa Nacional, Oaxaca and Los Tuxtlas, Veracruz. March and May 2015. Methods: Dissections of inflorescences in every developmental stage from two populations, were examined using scanning electron micros- copy. Results: The inception patterns of the calyx (irregular), corolla (simultaneous), androecium (acropetally in alternate sectors) and gynoecium (precocious) agree with previous reports for non-myrmecophyic species of the Acacia genus. In mature stages, the presence of stomata is char- acteristic of bracts and petals.
