    IFAS DISEASE ALERT: BOXWOOD BLIGHT Causal organism: Cylindrocladium pseudonaviculatum or C. buxicola (Synonym: Calonectria pseudonaviculata) Fanny Iriarte, Mathews Paret, and Gary Knox University of Florida, North Florida Research and Education Center, Quincy Tim Schubert, David Davison, Jodi Hansen and Jeyaprakash Ayyamperumal Division of Plant Industry, Florida Department of Agriculture and Consumer Sciences Carrie Harmon, Dept. of Plant Pathology, University of Florida Basics Boxwoods (Buxus spp.) are commercially important evergreen ornamental plants with an annual market value of over $103 million in the United States. The first confirmed reports of Boxwood blight in the U.S were from Connecticut and North Carolina in November 2011, followed by confirmation in numerous states since then. In Florida, Boxwood blight was discovered in April 2015 in a commercial nursery in North Florida by the University of Florida, NFREC Plant Diagnostic Clinic and the Division of Plant Industry, FDACS. The disease was on liners of Common boxwood (B. sempervirens) and ‘Green Velvet ‘ (B. sinica var. insularis x B. sempervirens ‘Suffruticosa’) cultivars shipped from Oregon. Spread outside the Florida nursery has not been reported. No other occurrences have been detected/reported in the area as of May 18th, 2015. Shipment trace- forwards by DPI are underway. DPI and the nursery are currently implementing strategies to eradicate the pathogen from the location. Nursery personnel should be aware of the symptoms of boxwood blight and monitor plants in the nursery and landscape routinely. Symptom: Leaf spot The fungal pathogen infects leaves and branches of boxwoods, causing light or dark brown leaf spots with a dark or diffuse border.

Stafford Grand Cayman's birds suffered very badly as a result of Hurricane Ivan (11-12 Sept. 2004) & its aftermath, when there was little food or shelter. The preservation & re-planting of Cayman's indigenous (& a few that have become naturalized & grow in the wild) trees & shrubs, in clusters, rather than singly, will create a network of mini-woodlands to aid the re-establishment of bird populations. Listed are different species that provide suitable roosts & nesting sites & a year-round supply of fruits for BIRDS. Legend: endemic* grows only in the Cayman Islands & nowhere else in the world Salt-tolerance, drought tolerance and WIND-tolerance taken into account. Plants that are deep-rooted & slender-trunked offer less resistance to high winds & survive storms better than shallow-rooted, top heavy trees. Slow-growing trees are usually more wind-tolerant than fast growing trees. Some may be culturally significant or invasive, or both, eg Logwood Monoecious plants have separate male and female flowers on the same plant, eg Narrow-Leaf Ironwood. Dioecious plants have separate male and female flowers on different plants, eg Bitter Plum, Cabbage Tree, Fustic, Rosemary. No - Some plants are on the list that are NOT recommended for planting because they are very common and don't need human help, or invasive or harmful to people, exacerbate beach erosion or are hazardous in storms.

  • Woody and Herbaceous Plants Native to Haiti for Use in Miami-Dade Landscapes1
    Woody and Herbaceous Plants Native to Haiti For use in Miami-Dade Landscapes1 Haiti occupies the western one third of the island of Hispaniola with the Dominican Republic the remainder. Of all the islands within the Caribbean basin Hispaniola possesses the most varied flora after that of Cuba. The plants contained in this review have been recorded as native to Haiti, though some may now have been extirpated due in large part to severe deforestation. Less than 1.5% of the country’s original tree-cover remains. Haiti’s future is critically tied to re- forestation; loss of tree cover has been so profound that exotic fast growing trees, rather than native species, are being used to halt soil erosion and lessen the risk of mudslides. For more information concerning Haiti’s ecological plight consult references at the end of this document. For present purposes all of the trees listed below are native to Haiti, which is why non-natives such as mango (the most widely planted tree) and other important trees such as citrus, kassod tree (Senna siamea) and lead tree (Leucanea leucocephala) are not included. The latter two trees are among the fast growing species used for re-forestation. The Smithsonian National Museum of Natural History’s Flora of the West Indies was an invaluable tool in assessing the range of plants native to Haiti. Not surprisingly many of the listed trees and shrubs 1 John McLaughlin Ph.D. U.F./Miami-Dade County Extension Office, Homestead, FL 33030 Page | 1 are found in other parts of the Caribbean with some also native to South Florida.

  • Notes on Florida's Endangered and Threatened Plants 1
    NOTES ON FLORIDA'S ENDANGERED AND THREATENED PLANTS 1 Nancy C. Coile2 The Regulated Plant Index is based on information provided by the Endangered Plant Advisory Council (EPAC), a group of seven individuals who represent academic, industry, and environmental interests (Dr. Loran C. Anderson, Dr. Daniel F. Austin,. Mr. Charles D. D aniel III, Mr. David M . Drylie, Jr., Ms. Eve R. Hannahs, Mr. Richard L. Moyroud, and Dr. Daniel B. Ward). Rule Chap. 5B-40, Florida Administrative Code, contains the "Regulated Plant Index" (5B-40.0055) and lists endangered, threatened, and commercially exploited plant species for Florida; defines the categories; lists instances where permits may be issued; and describes penalties for vio lations. Copies of this Rule may be obtained from Florida Department of Agriculture and Consumer Services, Division of Plant Industry, P. O. Box 147100, Gainesville, Fl 32614-7100. Amended 20 September 2000, the "Regulated Plant Index" contains 415 endangered species, 113 threatened species, and eight commercially exploited species. Descriptions of these rare species are often difficult to locate. Florida does not have a single manual covering the flora of the entire state. Long and Lakela s manual (1971) focuses on the area south of Glades County; Clewell (1985) is a guide for the Panhandle; and Wunderlin (1998) is a guide for the entire state of Florida but lacks descriptions. Small (1933) is an excellent resource, but must be used with great care since the nomenclature is outdated and frequently disputed. Clewell (1985) and Wunderlin (1998 ) are guides with keys to the flora, but lack species descriptions. Distribution maps (Wund erlin and Hansen, 200 0) are available over the Internet through the University of South Florida Herbarium [www.plantatlas.usf.edu/].

    Life: The Excitement of Biology 3(4) 254 Spatiotemporal Changes of the Herpetofaunal Community in Mount Resaca and Luis Peña Cay, Culebra National Wildlife Refuge, Culebra, Puerto Rico1 Alejandro Ríos-Franceschi2,3, Juan G. García-Cancel3, Fernando J. Bird-Picó3, and Luis D. Carrasquillo3 Abstract: Culebra, which is an archipelago that forms part of the Puerto Rican Bank, has had a limited scope of biological studies, provided the basis for this work. Culebra’s terrestrial resources were disturbed since the early 1900’s until the 1970’s. Since the 1970’s, a natural reserve, called the Culebra National Wildlife Refuge, has been managed by the United States Fish and Wildlife Service. The purpose of this research is to update the species list of reptiles and amphibians on the Island as well as to examine how spatial and temporal changes affect the diversity and abundance of its herpetofauna. Twenty species of reptiles and amphibians placed in thirteen families were identified. Two new records for Mount Resaca are Eleutherodactylus coqui Thomas, 1966 and Eleutherodactylus cochranae Grant, 1932. Meanwhile, Anolis pulchellus Duméril and Bibron, 1837 is a new record for the Luis Peña Cay. Mount Resaca has greater species richness, ten more species than the Luis Peña Cay, three species of amphibians and seven species of reptiles. The differences in herpetofaunal biodiversity (e.g. Shannon Wiener, Simpson’s Index and Margalef’s Index) between Mount Resaca and the Luis Peña Cay were statistically significant. Abiotic factors, such as temperature and humidity, and biotic factors, such as vegetation and the presence of other animal species, possibly influence the relative abundances within these communities.

Traditional herbal mixtures in Eastern Cuba are investigated through interviews with 130 knowledgeable people and traditional healers of the provinces of Santiago de Cuba and Guantánamo. One hundred seventy plant species and other products are used in 199 formulas, galones being the more complex. Cocos nucifera L. (Arecaceae), Bidens pilosa L. (Asteraceae), Cissus sicyoides L.
