  • Scientific Assessment of Ephedra Species (Ephedra Spp.)
    Annex 3 Ref. Ares(2010)892815 – 02/12/2010 Recognising risks – Protecting Health Federal Institute for Risk Assessment Annex 2 to 5-3539-02-5591315 Scientific assessment of Ephedra species (Ephedra spp.) Purpose of assessment The Federal Office of Consumer Protection and Food Safety (BVL), in collaboration with the ALS working party on dietary foods, nutrition and classification issues, has compiled a hit list of 10 substances, the consumption of which may pose a health risk. These plants, which include Ephedra species (Ephedra L.) and preparations made from them, contain substances with a strong pharmacological and/or psychoactive effect. The Federal Ministry of Food, Agriculture and Consumer Protection has already asked the EU Commission to start the procedure under Article 8 of Regulation (EC) No 1925/2006 for these plants and preparations, for the purpose of including them in one of the three lists in Annex III. The assessment applies to ephedra alkaloid-containing ephedra haulm. The risk assessment of the plants was carried out on the basis of the Guidance on Safety Assessment of botanicals and botanical preparations intended for use as ingredients in food supplements published by the EFSA1 and the BfR guidelines on health assessments2. Result We know that ingestion of ephedra alkaloid-containing Ephedra haulm represents a risk from medicinal use in the USA and from the fact that it has now been banned as a food supplement in the USA. Serious unwanted and sometimes life-threatening side effects are associated with the ingestion of food supplements containing ephedra alkaloids. Due to the risks described, we would recommend that ephedra alkaloid-containing Ephedra haulm be classified in List A of Annex III to Regulation (EC) No 1925/2006.

  • Tree Management Plan DRAFT Otter Mound Preserve, Marco Island, FL
    Tree Management Plan DRAFT Otter Mound Preserve, Marco Island, FL Prepared by: Alexandra Sulecki, Certified Arborist FL0561A February 2013 INTRODUCTION The Otter Mound Preserve is a 2.45-acre urban preserve located at 1831 Addison Court within the boundaries of the City of Marco Island in southwestern Collier County, Florida. The preserve lies within the “Indian Hills” section, on the south side of the island. Three parcels totaling 1.77 acres were acquired by Collier County under the Conservation Collier Program in 2004. An additional adjoining .68 acre parcel was acquired in 2007. The property was purchased primarily to protect the existing native Tropical Hardwood Hammock vegetation community. Tropical Hardwood Hammock is becoming rare in Collier County because its aesthetic qualities and location at higher elevations along the coast make it attractive for residential development. Tropical Hardwood Hammock is identified as a priority vegetation community for preservation under the Conservation Collier Ordinance, (Ord. 2002- 63, as amended, Section 10 1.A). The Florida Natural Areas Inventory (FNAI) associates Tropical Hardwood Hammock with a natural community identified as “Shell Mound,” which is imperiled statewide (ranking of S2) and globally (ranking of G2), due to its rarity (Guide to the Natural Communities of Florida, 2010). The preserve is managed for conservation, restoration and passive public use. The Preserve’s forest has conservation features that draw visitors. Its canopy serves as an important stopover site for a variety of migratory bird species and is home to the Florida tree snail (Liguus fasciatus), a Florida Fish and Wildlife Conservation Commission (FWC) Species of Special Concern.

Gann, Executive Director Submitted to CarolAnn Sharkey Key West Botanical Garden 5210 College Road Key West, Florida 33040 and Kate Marks Heritage Preservation 1012 14th Street, NW, Suite 1200 Washington DC 20005 Introduction The Key West Botanical Garden (KWBG) is located at 5210 College Road on Stock Island, Monroe County, Florida. It is a 7.5 acre conservation area, owned by the City of Key West. The KWBG requested that The Institute for Regional Conservation (IRC) conduct a floristic evaluation of its natural areas and grounds and to provide recommendations. Study Design On August 9-10, 2005 an inventory of all vascular plants was conducted at the KWBG. All areas of the KWBG were visited, including the newly acquired property to the south. Special attention was paid toward the remnant natural habitats. A preliminary plant list was established. Plant taxonomy generally follows Wunderlin (1998) and Bailey et al. (1976). Results Five distinct habitats were recorded for the KWBG. Two of which are human altered and are artificial being classified as developed upland and modified wetland. In addition, three natural habitats are found at the KWBG. They are coastal berm (here termed buttonwood hammock), rockland hammock, and tidal swamp habitats. Developed and Modified Habitats Garden and Developed Upland Areas The developed upland portions include the maintained garden areas as well as the cleared parking areas, building edges, and paths.

    Legume-feeding Lepidoptera of the Florida Keys: potential competitors of an endangered lycaenid butterfly Sarah R. Steele Cabrera1,2,*, James E. Hayden3, Jaret C. Daniels1,2, Jake M. Farnum4, Charles V. Covell Jr.1, and Matthew J. Standridge1 Abstract Two Fabaceae in the Florida Keys, Pithecellobium keyense Coker and Guilandina bonduc Griseb., have been of interest because they are the larval host plants for the endangered Miami blue butterfly (Cyclargus thomasi bethunebakeri [Comstock & Huntington]; Lepidoptera: Lycaenidae). As a part of ongoing research and conservation for this butterfly, wild host plant material has been periodically collected in order to supplement a captive colony ofC. t. bethunebakeri located in Gainesville, Florida, USA. In examining this plant material, 26 lepidopterans were detected, includ- ing several host records, a new continental record, and 2 likely undescribed species, 1 Aristotelia (Gelechiidae) and 1 Crocidosema (Tortricidae). Our results expand the geographic, life-history, and taxonomic understanding of lepidopteran herbivores that use P. keyense and G. bonduc in South Florida. Key Words: Pithecellobium keyense; Guilandina bonduc; Fabaceae; herbivory Resumen En los Cayos de Florida, habitan dos especies de plantas hospederas críticas para el ciclo de vida de la mariposa Miami blue (Cyclargus thomasi bethunebakeri [Comstock y Huntington]; Lepidoptera: Lycaenidae), la cual está en peligro de extinción.

Correo electrónico: [email protected] *Autor de correspondencia Resumen La influencia que tiene la radiación solar sobre la germinación y emergencia de plántulas no ha sido descrita para muchas de las especies tropicales de importancia maderable. La presente investigación se enfoca en la emergencia de plántulas de taxa maderables nativas de la Península de Yucatán bajo diferentes grados de sombra (0%, 35%, 60% y 90%). Para ello, se realizó la evaluación de las especies de Caesalpinia mollis (chakté) , (Piscidia piscipula) (jabín) y jujuché (Albizia tomentosa). C. molli y A. tomentosa presentaron diferencias entre tratamientos (p < 0.0001 y p < 0.0,1 respectivamente), ambas tuvieron mayor emergencia de plántulas con la luminosidad más elevada (0% de sombra). El tiempo de inicio de emergencia de las plántulas fue de cuatro a cinco días y la emergencia del 100% se logró en menos días con el 90% de sombra para las tres especies. Los resultados expresan que el porcentaje de sombra influye en la emergencia total de las plántulas. Palabras clave: Emergencia; sombra; nativas; plántulas. Abstract The influence of solar radiation on the germination and emergence of seedlings has not been described for many of the timber species present in the tropics.

    MEDlCINAL PLANTS OF JAMAICA. PARTS 1 & 11. By G. F. Asprey, M.Sc., Ph.D. (B'ham.), Professor of Botany, U.C.W.l. and Phyllis Thornton, B.Sc. (Liverpool), Botanist Vomiting Sickness Survey. Attached to Botany Depart- ment, U.C.W.l. Reprinted from the West Indian Medical Journal. Vol. 2 No. 4. Vol. 3 No. 1. MEDICINAL PLANTS OF JAMAICA G. F. ASPREY AND PHYLLIS THORNTON PART I The use of local plants for medicinal remedies is a very prevalent practice in Jamaica. Among the poorer families, the morning meal frequently consists of nothing more than a cup of bush-tea prepared by steeping the leaves in hot water, with perhaps a small piece of bread or a little corn meal porridge. It is perhaps significant that the term breakfast is not used but 'taking' or ‘drinking' tea is substituted. Many of the plants used for treatment of colds and indigestion also provide the normal morning drinks. The large number of 'cold', 'fever' (which includes malaria) and 'indigestion' remedies is of some interest as providing a guide to the frequency of these complaints. The claims made for some of the plants may occasionally be justified by their chemical constituents. Some of them are, or have been, in the pharmacopoeias. On the other hand, in many cases the claims either have little justification or remain to be substantiated. Many of the doses used are of an unpleasant and even drastic nature. This may account for their popularity in view of the general impression that medicine must be unpleasant to be efficacious.
