Weed Survey of Springvale Station
Weed Survey of Springvale Station Paul Williams Vegetation Management Science August 2016 1 Summary Springvale Station, approximately 50 km to the south-west of Cooktown, covers around 56,000 hectares. The property was purchased by the Queensland Government in May 2016 and is currently managed by the Queensland Department of Environment and Heritage Protection (EHP). A survey of weeds (i.e. invasive exotic plants) observable from the main vehicle tracks on Springvale Station was undertaken by Peter Munt, Keith Smith and Paul Williams on the 4 and 5 August 2016. The survey covered the northern half of the property and included inspections at points on the East, Granite and West Normanby Rivers. It also included surveys of two mine lease areas on the west Normanby River. At each record point, a GPS-derived location was documented and the abundance of all weeds in the surrounding area noted, based on an estimate of their percentage ground cover, grouped into categories (Table 1). Table 1. The abundance categories used for mapping the abundance of each weed (based on the categories used by Weeds of National Significance and the Queensland DPI). Weed Abundance Category Percentage cover of weed Scattered < 1 % cover Low 1 – 9 % cover Moderate 10 – 29 % cover High 30 – 49 % cover Very High ≥ 50 % cover Weed abundance was documented at regular intervals and where weed species composition or abundance changed. A total of 61 weeds were observed (Appendix 1). Nine of the weeds are declared as Category 3 under the new Queensland Biosecurity Act 2014. -

Corresponding author: Orlando O. Ortiz, [email protected]. Abstract In the present study, we report 46 new records of vascular plants species from Panama. The species belong to the fol- lowing families: Anacardiaceae, Apocynaceae, Aquifoliaceae, Araceae, Bignoniaceae, Burseraceae, Caryocaraceae, Celastraceae, Chrysobalanaceae, Cucurbitaceae, Erythroxylaceae, Euphorbiaceae, Fabaceae, Gentianaceae, Laciste- mataceae, Lauraceae, Malpighiaceae, Malvaceae, Marattiaceae, Melastomataceae, Moraceae, Myrtaceae, Ochnaceae, Orchidaceae, Passifloraceae, Peraceae, Poaceae, Portulacaceae, Ranunculaceae, Salicaceae, Sapindaceae, Sapotaceae, Solanaceae, and Violaceae. Additionally, the status of plant collections in Panama is discussed; we focused on the areas where we identified significant information gaps regarding real assessments of plant biodiversity in the country. -

Field and herbarium surveys of the phanerogamic flora of the Ubajara National Park, located on the Brazilian Northeast, were made and analyses on phenology and dispersal syndromes were performed. -
Floristic Composition of the South-Central Florida Dry Prairie Landscape Steve L
Floristic Composition of the South-Central Florida Dry Prairie Landscape Steve L. Orzell Avon Park Air Force Range, 29 South Blvd., Avon Park Air Force Range, FL 33825-5700 [email protected] Edwin L. Bridges Botanical and Ecological Consultant, 7752 Holly Tree Place NW, Bremerton, WA 98312-1063 [email protected] ABSTRACT Floristic composition of the Florida dry prairie landscape was compiled from 291 sites in nine south-central peninsular counties. Floristic lists were based upon field inventory and compilation from reliable sources to- taling 11,250 site and community type-specific observations and were analyzed by region (Kissimmee River, Desoto/Glades “Big Prairie,” and Myakka). The known vascular flora consists of 658 vascular plant taxa, rep- resenting 317 genera and 115 families. Families with the highest number of species are Poaceae (103), Asteraceae (78), Cyperaceae (76), Fabaceae (23), Scrophulariaceae (20), and Orchidaceae (18). The most diverse genera are Rhynchospora (29), Dichanthelium (17), Ludwigia (13), Xyris (12), and Andropogon (11). Of this flora 24 taxa are endemic to central or southern peninsular Florida, primarily within the pine savanna- flatwood/dry prairie landscape, and 41 taxa are of Floridian biotic affinity. Although most species are not re- gionally specific, a few (Carphephorus carnosus, Ctenium aromaticum, and Liatris spicata) appear to be ab- sent from the Myakka prairie region, while Marshallia tenuifolia appears to be absent from both the Desoto/ Glades and Myakka prairie regions. Within the dry prairie landscape Hypericum edisonianum is restricted to the Desoto/Glades region. A few other species somewhat differentiate between prairie regions; however, most occur in other habitats in the counties where they are absent or nearly absent from dry prairie. -

[var. pyramidalis (Beauv.) Veldk., incl. S. jacquemontii Kunth] from Africa and America. The Indian species generally known - S. as S. tremulus a superfluous name for S. virginicus (L.) Kunth -is reduced to a subspecies of humilis Presl. Sporobolus poiretii (R. & S.) Hitchc., long misapplied for S. indicus, is a synonym ofS. junceus (Beauv.) Kunth. Five new sections are distinguished. The correct name for Thysanolaena maxima (Roxb.) O. Ktze is T. latifolia (Roxb. ex Hornem.) Honda. Introduction The described R.

He regarded A. virginica L. as very (which was quite correct that but he retainedit in a species of Sporobolus as well), Agrostis, possibly because he had not seen any fruiting material (which is rare) and also because this species has exceptional long glumes. -
