Biological Resources and Management
Vermilion flycatcher The upper Muddy River is considered one of the Mojave’s most important Common buckeye on sunflower areas of biodiversity and regionally Coyote (Canis latrans) Damselfly (Enallagma sp.) (Junonia coenia on Helianthus annuus) important ecological but threatened riparian landscapes (Provencher et al. 2005). Not only does the Warm Springs Natural Area encompass the majority of Muddy River tributaries it is also the largest single tract of land in the upper Muddy River set aside for the benefit of native species in perpetuity. The prominence of water in an otherwise barren Mojave landscape provides an oasis for regional wildlife. A high bird diversity is attributed to an abundance of riparian and floodplain trees and shrubs. Contributions to plant diversity come from the Mojave Old World swallowtail (Papilio machaon) Desertsnow (Linanthus demissus) Lobe-leaved Phacelia (Phacelia crenulata) Cryptantha (Cryptantha sp.) vegetation that occur on the toe slopes of the Arrow Canyon Range from the west and the plant species occupying the floodplain where they are supported by a high water table. Several marshes and wet meadows add to the diversity of plants and animals. The thermal springs and tributaries host an abundance of aquatic species, many of which are endemic. The WSNA provides a haven for the abundant wildlife that resides permanently or seasonally and provides a significant level of protection for imperiled species.

Integrated Pest Management Against Rhynchophorus Ferrugineus
Integrated Pest Management against Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) and Paysandisia archon (Burmeister, 1880) (Lepidoptera: Castniidae) on palms In Cyprus, the majority of palms grown on the island are more of historic and decorative interest and less of date production. In the case of palm pests, the problem of their control is not an entomological one, but mainly, one of management. For the successful management of economically important pests like red palm weevil (RPW) Rhynchophorus ferrugineus and palm borer Paysandisia archon (PA), it is mandatory to adopt a combination of methods and approaches, including public awareness campaigns (lectures, seminars, training, information posted on the Agricultural Research Institute and the Department of Agriculture websites, informative leaflets/posters, radio and TV presentations, popular articles in local magazines and newspapers), quarantine, cultural, mechanical, biological, pheromone trapping, chemical treatments, etc. Before launching any pest control programme, the quantitative relationship between yield and/or palm tree losses and pest population levels are estimated in order to compute the economic injury level for each pest. Therefore, combined use of all the available management measures in a rational way is the basis for the development of integrated pest control strategies. For the success of IPM, all methods listed above should be combined in a judicious manner and implemented accordingly. Just following a few methods and neglecting other proven methods -
Washingtonia × Filibusta (Arecaceae: Coryphoideae), a New Hybrid from Cultivation
Hodel, D.R. 2014. Washingtonia × filibusta (Arecaceae: Coryphoideae), a new hybrid from cultivation. Phytoneuron 2014-68: 1–7. Published 1 July 2014. ISSN 2153 733X WASHINGTONIA × FILIBUSTA (ARECACEAE: CORYPHOIDEAE), A NEW HYBRID FROM CULTIVATION DONALD R. HODEL University of California Cooperative Extension 700 W. Main Street Alhambra, California 91801 [email protected] ABSTRACT Washingtonia × filibusta , a hybrid between W. filifera H. Wendl. and W. robusta H. Wendl., is named and described from a cultivated plant in Indio, California. Washingtonia filifera (California fan palm) and W. robusta (Mexican fan palm) have long been cultivated and are especially common landscape subjects in California, western Arizona, and southern Nevada as well as other regions with a suitable climate. They frequently grow side-by-side in landscape settings, providing ample opportunity for hybridization. Hybrid plants are intermediate between the parents and for the past 30 years have become common subjects in the nursery and landscape trade, where they are recognized for their different appearance and cultivation requirements. Washingtonia × filibusta Hort. ex Hodel, sp. hyb. nov. (W. filifera H. Wendl. × W. robusta H. Wendl.). TYPE : CULTIVATED. USA . California.

Acacia Pendula (Weeping Myall)
Cunninghamia Date of Publication: 17 December 2014 A journal of plant ecology for eastern Australia ISSN 0727- 9620 (print) • ISSN 2200 - 405X (Online) Acacia pendula (Weeping Myall) in the Hunter Valley of New South Wales: early explorers’ journals, database records and habitat assessments raise doubts over naturally occurring populations Stephen Bell1,3 & Colin Driscoll2 1 Eastcoast Flora Survey, PO Box 216 Kotara Fair NSW 2289, [email protected] 2 Hunter Eco, PO Box 1047 Toronto NSW 2283, [email protected] 3 School of Environmental and Life Sciences, University of Newcastle, Callaghan NSW 2308 Abstract: Acacia pendula, Weeping Myall, (family Fabaceae) is the most legislatively protected plant species in the New South Wales Hunter Valley. Under the NSW Threatened Species Conservation Act 1995 it is listed as an Endangered Population (in the Hunter Valley) and as a component of two Endangered Ecological Communities (one in the Hunter, one elsewhere in NSW); it is also listed as a Critically Endangered Ecological Community (in the Hunter Valley) on the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and listed as threatened in three other eastern Australian States. To ascertain the likely original distribution of stands of Acacia pendula in the Hunter Valley, this paper examines the writings of early Australian explorers, herbarium and database records, and the species habitat attributes across NSW. None of the journals examined, including those of botanist/explorer Allan Cunningham (who originally collected Acacia pendula from the Lachlan River in 1817), Thomas Mitchell or Ludwig Leichhardt, make note of the species for the Hunter Valley. Several explorers do, however, record Acacia pendula regularly (>100 times) across other parts of NSW, Queensland, and South Australia. -
Going to Sustainable
GOING TO SUSTAINABLE Lowering Landscape and Garden Maintenance Including Better Ways to Water and How to Save Water © Joseph L. Seals, 2008, 2009 Copyright Joseph L. Seals, 2008, 2009 LOWERING MAINTENANCE REDUCING MAINTENANCE IN THE PLANNING STAGES Unfortunately, maintenance of the landscape is often assumed or overlooked during the planning and design phase of a project 1) Keep the planting design simple. The more elaborate the plan and planting -- Numbers of plants, variety of plants, -- less than simple lines and shapes -- … the more maintenance is required. For instance, lawn areas need to be plotted so that mowing, edging and periodic maintenance can be accomplished easily. -- Avoid tight angles and sharp corners. -- wide angles, gentle, sweeping curves, and straight lines are much easier to mow. -- Make certain each plant in the plan serves a purpose. 2) Select the right plant for the right place We all know that there are “sun plants” for sunny spots and “shade plants” for shady spots. And we don’t plant “sun plants” in shade nor do we plant “shade plants” in sun. And some of us know that there are drought-tolerant plants that like dry soil and little water -- and there are moisture-loving plants that like their feet wet. And we don’t mix those up either. Such “mix ups” result in everything from the obvious: outright death of the plant involved to a subtly stressed plant that shows various symptoms of “disease” -- whether it’s an actual organism or a physiological condition. Copyright Joseph L. Seals, 2008, 2009 Every time you push a plant beyond its natural adaptations, abilities, and tolerances, you invite problems and you invite higher maintenance When choosing the right plant, start with THE BIG PICTURE: We have a Mediterranean climate. -

Their garden comprises three and a half acres of Australian plants in a setting inspired by open grassy woodlands. Those who attended a previous meeting at Glendeuart will notice significant developments including terraced landscaping and dry stone walling to accommodate a growing collection of Grevilleas and other Australian plants. Grevillea arenaria identifying features Photo by Mark Noake Australian Plant Society South East NSW Newsletter 120 July 2016 Page 1 An introductory talk will include a short tour of our Southeast Group’s website, showing how to easily access a wealth of information. Then follows a simple explanation of the plant features used by botanists when identifying Grevilleas, which will be illustrated with lots of images and no exams. Carolyn and Mark’s inspiration for growing Grevillea species as found in the wild and the fun to be had trying to protect rare and endangered plants will be discussed. Support will be sought on dealing with their inability to walk past a “different” plant in a nursery without purchasing it.
