Variation in Seed Production and Germination in 22 Rare and Threatened Western Australian Verticordia (Myrtaceae)
Journal of the Royal Society of Western Australia, 84:103-110, 2001 Variation in seed production and germination in 22 rare and threatened Western Australian Verticordia (Myrtaceae) A Cochrane1, K Brown2, S Cunneen3 & A Kelly4 1Threatened Flora Seed Centre, Department of Conservation and Land Management, Locked Bag 104, Bentley Delivery Centre, Perth WA 6983 2Environmental Weeds Action Network, 108 Adelaide Terrace, East Perth WA 6000 3CSIRO Centre for Mediterranean Agricultural Research, Floreat WA 6014 424 Carnarvon St, East Victoria Park WA 6100 email: [email protected] Manuscript received August 2000, accepted March 2001 Abstract This study investigates the reproductive potential of 22 rare and threatened Western Australian taxa in the genus Verticordia (Myrtaceae) over a 5-year period. Considerable inter- and intra-specific variation in both seed production and germinability was demonstrated for the majority of taxa. The seed to flower ratio, or “seed set”, ranged from 0% to 68% with an overall mean of 21% in 82 accessions representing seed from 48 populations of the 22 taxa. Percentage germination ranged from 7% to 100% with an average of 49% for 68 accessions. The precariously low annual reproductive capacity of some of the more restricted and critically endangered taxa threatens their survival and unexpected disturbance events may result in population decline or even localised extinction. Mitigation measures such as the reintroduction of plant material into new sites and the enhancement of existing populations through additional plantings may be warranted for many of Western Australia’s rare and threatened Verticordia. Keywords: Verticordia, seed production, germination Introduction prominently displayed feathery flowers are borne singly but appear as heads or spikes and are generally brightly Verticordia (family Myrtaceae, sub-family coloured, ranging from yellow to red to purple. -

The pandemic has made essential self distancing and quarantining to arrest the spread of the Corona virus. As a result, most APS activities have been shelved for the time being. Being in isolation at home has been a mixed blessing. -

Flowers, Posts and Plates of Dirk Hartog Island
Flowers, Posts and Plates of Dirk Hartog Island Lesley Brooker FLOWERS POSTS AND PLATES January 2020 Home Flowers, Posts and Plates of Dirk Hartog Island Lesley Brooker For the latest revision go to https://lesmikebrooker.com.au/Dirk-Hartog-Island.php Please direct feedback to Lesley Brooker at [email protected] Home INTRODUCTION This document is in two parts:- Part 1 — FLOWERS is an interactive reference to some of the flora of Dirk Hartog Island. Plants are arranged alphabetically within families. Hyperlinks are provided for quick access to historical material found on-line. Attention is drawn (in the green boxes below the species accounts) to some features which may help identification or may interest the reader, but these are by no means diagnostic. Where technical terms are used, these are explained in parenthesis. The ultimate on-line authority on the Western Australian flora is FloraBase. It provides the most up-to-date nomenclature, details of subspecies, flowering periods and distribution maps. Please use this guide in conjunction with FloraBase. Part 2 — POSTS AND PLATES provides short historical accounts of some the people involved in erecting and removing posts and plates on Dirk Hartog Island between 1616 and 1907, and those who may have collected plants on the island during their visit. Home FLOWERS PHOTOGRAPHS REFERENCES BIRD LIST Home Flower Photos The plants are presented in alphabetical order within plant families - this is so that plants that are closely related to one another will be grouped together on nearby pages. All of the family names and genus names are given at the top of each page and are also listed in an index. -

Post-Fire Recovery of Woody Plants in the New England Tableland Bioregion
Post-fire recovery of woody plants in the New England Tableland Bioregion Peter J. ClarkeA, Kirsten J. E. Knox, Monica L. Campbell and Lachlan M. Copeland Botany, School of Environmental and Rural Sciences, University of New England, Armidale, NSW 2351, AUSTRALIA. ACorresponding author; email: [email protected] Abstract: The resprouting response of plant species to fire is a key life history trait that has profound effects on post-fire population dynamics and community composition. This study documents the post-fire response (resprouting and maturation times) of woody species in six contrasting formations in the New England Tableland Bioregion of eastern Australia. Rainforest had the highest proportion of resprouting woody taxa and rocky outcrops had the lowest. Surprisingly, no significant difference in the median maturation length was found among habitats, but the communities varied in the range of maturation times. Within these communities, seedlings of species killed by fire, mature faster than seedlings of species that resprout. The slowest maturing species were those that have canopy held seed banks and were killed by fire, and these were used as indicator species to examine fire immaturity risk. Finally, we examine whether current fire management immaturity thresholds appear to be appropriate for these communities and find they need to be amended. Cunninghamia (2009) 11(2): 221–239 Introduction Maturation times of new recruits for those plants killed by fire is also a critical biological variable in the context of fire Fire is a pervasive ecological factor that influences the regimes because this time sets the lower limit for fire intervals evolution, distribution and abundance of woody plants that can cause local population decline or extirpation (Keith (Whelan 1995; Bond & van Wilgen 1996; Bradstock et al. -

Their garden has been open to the public on several occasions for various charities. They ran a wholesale nursery for several years specialising in Eremophilas. Graham and Maree’s current project is growing plants, landscaping and overseeing the planting of the gardens surrounding the new building of their Church which was opened recently. They first became involved with Australia’s inland deserts in 2002 with an organisation called Desert Discovery as part of the Botany team. In 2008, Maree became the Botany Team Leader, while Graham was involved with the photography and identification of specimens. They have done volunteer work for Australian Wildlife Conservancy, Friends of the Great Victoria Desert, Victorian and Western Australian Herbariums in collecting, identifying and processing specimens.
