SEA OXEYE by Roger L. Hammer [ excerpt from printed newsletter ]
THE FERNS FROM HELL by Don Keller [ excerpt from printed newsletter ]


Tuesday, March 28, 7:30 p.m., Fairchild Tropical Garden, 10901 Old Cutler Road.

"Sustainable Landscaping" - Dr. John H. Parker, Professor of Environmental Science and Chemistry and Coordinator of the Environmental Studies Program at Florida International University.

Urban landscaping can play a crucial role as we try to achieve long term environmental sustainability. Sustainable development requires the integration of environmental, social and economic issues and perspectives. Clearly, sustainable landscaping should focus on local ecological issues such as impacts on natural areas and solid waste management as well as global environmental issues such as climate change. In addition, sustainable landscaping projects should prompt the building of social capital by emphasizing community-building, education particularly our youth and partnering with other organizations.

Our speaker is a member of DCFNPS and has been active in many local environmental programs. His research has focused on ecological landscaping, passive solar cooling, energy and resource conservation, energy policy and environmental education.

Thanks in advance to refreshment donors: Maria Elena Navarro (drinks and ice) and Kristie Doyne Bailey and Joe Barros (snacks). If you would like to donate an extra-special plant, other item or service to auction (instead of raffle), please call Tony Koop at 305-662-2876 or 305-284-5364. You or your business will be acknowledged in the Tillandsia.

Field trips are for the study of plants and enjoyment of nature by FNPS members and their invited guests. Collecting is not permitted. Become a member so you may enjoy these activities!

Saturday, March 18: Sugarloaf Key. This interesting, mature pine forest with palm and hardwood understory, perhaps the southernmost stand of Pinus elliottii var. densa in the US, has not burned for some time. This forest and nearby coastal areas contain a large variety of species, including Vanilla barbellata.

Saturday, March 25: Beginning Botany and Natural History in Everglades National Park. After a very well-received start in January, Tony Koop continues his series of easy and informative walks for the beginning botanist. This time the natural history of three habitats in the park (pineland, hammock and finger glade) will be featured along with plant identification. Walking will be easy and on trails.

Sunday, April 9: Corkscrew Marsh (Collier County). This area (not Corkscrew Swamp Sanctuary) is a 6,825-acre tract purchased as part of the Corkscrew Regional Ecosystem Watershed project. It has pine flatwoods, oak and palm hammocks and 5,000 acres of marsh -- good possibilities for lots of spring wildflowers. Three hiking trails totaling 5 miles have been developed from old trails used for ranching and hunting.

Congratulations to Marilyn Lindsley, an 11th grade student at Westminster Christian School! Marilyn’s curiosity, her careful observations of native plants and her ability has led her to win this year's George N. Avery Award for an Outstanding Science Fair Project from the Dade Chapter of the Florida Native Plant Society.

On one of many family boat trips into Biscayne Bay National Park, Marilyn noticed that a deep tidal pool at the family's favorite swimming spot near Eliot Key had a clear sandy bottom while the surrounding bay bottom was covered with sea grass. Her curiosity led her to research why with both extensive online and library research as well as careful environmental monitoring.

She found that the native sea grass in the area was turtle grass (Thalassia testudinum). After conducting several physical and chemical tests over several visits to the site. Ms. Lindsley concluded that temperature was the limiting factor that prevented the turtle grass from colonizing the site.

Ms. Lindsley is an honors student and maintains an extremely active schedule. Some of her endeavors include Student Council Secretary, first flute in the band, National Honor Society, the Photography Club, the Girl's Bible Study group and student athletic trainer for several teams. Her efforts as a trainer clearly will help her career plans -- Marilyn plans to go into medicine.

Marilyn will present her project at the March meeting in Dade.

On February 26, about 3000 people turned out for the Nature Conservancy’s (TNC) second annual Native Plant Fair on Sugarloaf Key. The plant give-away is part of TNC’s Florida Keys Initiative efforts to encourage an awareness of the important role natives play in the environment, and to show that while perhaps not as colorful as some exotic species, many native plants have traits that are highly appreciated by landscapers as well as wildlife.

The event was established last year to help restore lower Keys landscapes devastated by the winds and salt-water flooding of Hurricane Georges in 1998. TNC coordinated donations by local businesses and citizens, and with a big financial boost from Key West’s City Electric, purchased thousands of plants which were given away (3 per household) to residents impacted by the storm.

This year’s fair was another success. Over 3200 native plants were given away. Presentations were given on gardening with natives, attracting butterflies and creating backyard wildlife habitat by TNC, the Agricultural Extension, and Florida Park Service. Educational booths were set up by the Florida Native Plant Society, Florida Exotic Pest Plant Council, Florida Keys Audubon Society, Big Pine Key Botanical Society, County Agricultural Extension and Master Gardeners program, City Electric, Bahia Honda State Park, Florida Division of Forestry, and Friends and Volunteers of Refuges and Key West Botanical Garden.

The FNPS booth was staffed by Keys members who answered questions and gave out membership forms, plant lists from local state parks, and other reference materials. The tremendous public interest kept Margaret Gibson, Tina Henize, Lisa Gordon, Lenora Albury, Mike Norcross and Jim Duquesnel busy for the entire 5 hour event.

DCFNPS at the February Home Show. The chapter set up a display at the Coconut Grove Home on February 12-13. We were invited to complement adjacent plant programs. On Saturday WQBA’s Jesus Ramos broadcast his plant show from there, then gave a presentation. On Sunday Gary Allen from cable’s HGTV made presentations. We generated a little publicity for NATIVE plants and, with luck, attracted some new members. If literature dispersal is any indication of success, we did well, handing out over 800 various flyers and brochures and 56 membership applications. Many of these were bilingual information, furthering last year’s Hispanic Outreach efforts. Thanks to Carrie Cleland, Diane Otis and Sam Dawson for their help.

SEA OXEYE by Roger L. Hammer

[ An excerpt from the full article in the printed newsletter. ]

There are two native plants in our area with the name sea oxeye, and both can be found intermingling with other native species that share shoreline habitats. These are Borrichia frutescens and Borrichia arborescens, and are sometimes called "oxeye daisy", "sea daisy" or "bay marigold". They are typically found in salt marshes, salt flats, brackish marshes, and along the edges of mangrove swamps.

Sea oxeyes belong to the well-known Aster Family, Asteraceae, and the genus Borrichia is made up of seven species found in warm temperate and tropical America as well as the West Indies. Our two native species are fleshy-leaved shrubs that stand three to four feet tall and produce yellow, daisy-like flowers in spring and summer (principally May through September). Although the two species are similar in appearance, they are actually quite easy to tell apart. The more common species, Borrichia frutescens, forms dense, rhizomatous colonies and produces dull, gray-green leaves. The central disk flowers are stiff. Borrichia arborescens usually does not form dense stands and has succulent, glossy, bright green leaves. The central disk flowers of B. arborescens are soft. Butterflies (especially skippers) and small, iridescent, blue-green halictid bees visit the flowers of both species.

[ An excerpt from the full article in the printed newsletter. ]

We usually don't think of ferns as pests. None the less, the Florida Exotic Pest Plant Council (FEPPC) has rightly listed three alien fern species as invasive pest plants.

The Aquatic Plant Division of the US Geological Society has determined that two aquatic species, Water spangles, Salvinia auriculata, and S. molesta are such threats that they cannot be legally possessed in the U.S. In South America, S. auriculata has covered large water impoundments from shore to shore. Mats of it clog up dam outlets and power plant intakes. Salvinia molesta, found in some Fern Society members' collections, is equally harmful and also prohibited. So far, at least, neither species has escaped into Dade County natural areas, but Salvenia molesta has been reported as naturalized in Naples per Keith Bradley.

The three species on FEPPC’s hit list are Asian sword fern, Nephrolepis multiflora, and the vine-like Japanese climbing fern, Lygodium japonicum, and Old world climbing fern, L. microphyllum. The Nephrolepis has been spreading rampantly and crowding out the two native species that inhabit the same areas.

The native American climbing fern, Lygodium palmatum, is a very delicate species--rare everywhere--and almost impossible to cultivate. Yet the two very similar alien species are spreading beyond belief. In several areas of South Florida one or the other species sheath tree trunks, grow up into and smother the canopy killing the tree. Both Lygodiums above are also prohibited by the Dade County Landscape Code.

The search for biological control and native relatives of the pest plants.
