Greener Choices: Alternatives to Invasive-Exotic 6 7 Invasive EXOTIC Trees (Shade) Invasive EXOTIC Trees (Fall Color) Some exotic shade trees are able to invade due to fast growth and the Many invasive trees and shrubs form dense monotypic (consisting of only ability to produce large amounts of fruit. Birds and other wildlife that eat the one type) thickets that crowd out native vegetation and prevent any other prolific fruit become vessels for seed dispersal, thus making it hard to plant species from sprouting. contain and control the spread of these invasive trees.

Accepted 13 September, 2011 The aim of the study was to evaluate antimicrobial, antioxidant and anti-inflammatory activity of dry and fresh parts of leaf, stem and flower from the water extract of Wedelia trilobata. The antimicrobial activity of water extracts of fresh and dry parts against 9 different strains of bacteria and 11 different species of fungi were determined using standard method (paper disc method). The fresh parts water extracts showed that, leaf and flower extracts were most potent inhibiting all isolates of with different zones of inhibition but did not inhibited the growth of fungi tested. All the extracts have only moderately inhibited the all fungi. The minimum microbial concentration (MMC) of the active extract was observed from fresh part extracts of leaf, flower and stem ranged from 0.4 to 5.0 mg/ml for the sensitive bacteria.

Our speaker will be Nicole Perna Assistant Environmental Manager at Brevard County Barrier Island Sanctuary in Melbourne Beach. Conradina FNPS received a Keep Brevard Beautiful grant and helped achieve and enhance the native plants on the sanctuary. I grew up on a small barrier island in Brigantine, NJ where I spent endless days playing and exploring on its beaches and bays. Influenced by my father, I became active in local environmental efforts at an early age. I attend Stockton College locally studying Marine Biology and researching diamondback terrapins. I interned at the Marine Mammal Stranding Center rehabbing seals, dolphins and sea turtles. I moved to Florida after graduating and began work with Brevard County’s Environmentally Endangered Lands Program (EEL) restoring habitats and providing passive recreation opportunities. I also worked at the Brevard Zoo taking care of some amazing creatures like White Rhinos, Next Chapter Meeting Giraffe, Kilspringers, Ostrich etc.

  • Great Wildflowers for Dry Landscapes
    Great Wildflowers for Dry Landscapes Landscaping with Florida’s native wildflowers and plants provides refuge for birds, bees and butterflies while creating “habitat highways” through urban settings. / bob peterson (cc by 2.0) / bob peterson (cc by Many Florida landscapes have sandy soils that are naturally dry and well-drained, even after heavy rain. Instead of mulching or amending lantana involucrata these soils, embrace them and create a unique landscape by planting native wildflowers and grasses suited to dry conditions.

  • Chromosome Numbers in Compositae, XII: Heliantheae
    SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae.

  • USDA Forest Seroice Research Note S E- 177 July 1971
    USDA Forest Seroice Research Note S E- 177 July 1971 CHOPPING AND WEBBING CONTROL SAW-PALMETTO IN SOUTH FLORIDA1 Abstract.--Saw-palmetto is one of the more troublesome plants growing in south Florida, and its control is often desirable in programs of range and timber management. Both cross-chopping and webbing (root plowing) proved to be ef­ fective control measures, but webbing appeared to be less effective on a moist site. Many other shrubs were also effectively reduced by these treatments. Saw-palmetto (Serenoa repens (Bartr.) Small) is the major under­ story shrub over much of the pine flatwoods. It is the dominant shrub on some 8.5 million acres of grazed forest land and 9 million acres of com­ mercial, nongrazed forest land in Florida (4) and is commonly associated with other shrubs over most of the pine-;Iregrass type. These shrubs are important competitors with forage and trees for soil moisture, nutri­ ents, light, and space. In dense stands of shrubs, particularly palmetto, yield and availability of forage is decreased, and cattle handling is more difficult. Wildfire is especially damaging to trees where shrubs contrib­ ute a large amount of combustible material. Most shrubs also impede planting and harvesting of pines. For these reasons, most land managers seek practical methods of shrub control. Fire has been used in the South for many years to alleviate these problems (6). Although burning temporarily reduces the size of saw­ palmetto, the plants are not killed but readily begin sprouting. These re­ sponses to fire are also true of most other southern shrubs.

The Ericaceae is very important in our area, with a great diversity of genera and species, many of them rather narrowly endemic. Our area is one of the north temperate centers of diversity for the Ericaceae. Along with Quercus and Pinus, various members of this family are dominant in much of our landscape.
