In This Issue



Tuesday, April 24, 7:30 p.m. at Fairchild Tropical Garden, 10901 Old Cutler Road.

South Florida plants and their beneficial fungi (mycorrhizae). Jack B. Fisher, Fairchild Tropical Garden

Most native plants are associated with soil fungi that form a symbiosis with the plant roots. These mycorrhizae are beneficial to the plant. Jack will describe and illustrate the various kinds of mycorrhizae. Results of greenhouse experiments show that mycorrhizae promote uptake of phosphorous from our sandy soils of pinelands and coastal dunes. Some native plants must form mycorrhizae in order to grow and reproduce under natural conditions. (Editor's note: This is not a "gardening with mycorrhizae" talk, but those involved in gardening, horticulture, tree-planting projects and restoration should start learning about the research on this topic.)

Also, the senior division winners of the chapter's George N. Avery Award at this year's science fair will make a presentation on their project "Evaluation of the Biodiversity Present within the Lichen Community of the Florida Everglades Ecosystem".

May 22 meeting: Invasive Exotic Organisms and the Ecology of Invasion. Dr. Robert Doren, Everglades Restoration Program.

Upcoming meeting: Tuesday, April 24 on Big Pine Key (note the date change!). Keys Butterflies, Alana Edwards, North American Butterfly Association. Location: Methodist Church across Key Deer Boulevard from Winn Dixie.

Alana Edwards is a recent graduate of the Environmental Sciences Masters Program from Florida Atlantic University. She will discuss the plants that can be used to attract butterflies to a Florida Keys garden, emphasizing Lower Keys specialties such as the Florida Leafwing and the Florida Duskywing. The plant ID workshop begins at 7 PM and the meeting follows at 7:30.

There will be a butterfly watching walk on prior to meeting. Meet at Blue Hole at noon to see Lower Keys specialties.

FNPS annual conference, May 10-13, Palm Harbor (Pinellas Co.). Members should have received the conference brochure and registration in March. Besides all the usual wonderful field trips and programs (including the conference theme presentations: "Biodiversity and Development: Striking the Balance"), the conference also includes a special series for homeowners and trade show (plants, gifts and garden items, educational exhibits) on Saturday. The home landscaping sessions may also be attended under a separate registration, and the trade show is free to everyone. Tell your friends! Call 305-255-6404 or 866-356-2848 if you need registration forms for the FNPS conference or the Homeowner Conference.

Native Plant Day at Castellow Hammock on March 24 was an unqualified success, thanks to the volunteers, speakers, raffle donors, vendors, park staff, Mother Nature, and the local media which carried our publicity. Several hundred attended, coming from as far as the Keys, Naples, and Boca Raton, and compliments are still coming in.

The 2001-2001 DCFNPS board was elected at the March meeting. Returning members are Carrie Cleland (President), Carol Farber (Secretary), Sam Dawson (Treasurer), Keith Bradley (now "past president"), Tony Koop (now Vice President), Bob Mihm, and Karsten Rist. We welcome new board members Manny Pomares, Jerry Russo and Lynka Woodbury and thank retiring board members Alma Dean and Lee Massey for their service over the past two years.

From the December, 1999, issue of Conservation Biology, the Journal of the Society for Conservation Biology.

New evidence suggests that the decline of songbirds is linked to the rise of non-native plants. Birds that nest in non-native plants lose more eggs to raccoons and other predators, according to research presented in the December issue of Conservation Biology. "Here is an ecological trap if there ever was one!" says Christopher Whelan of the Illinois Natural History Survey in Wilmington, Illinois, who co-authored the study with Kenneth Schmidt of the Department of Biology at the University of Memphis. Non-native shrubs are widespread through the Midwest and East Coast. "Introduced honeysuckle and buckthorn can dominate the understories of forest preserves, particularly small, fragmented preserves surrounded by urban sprawl," says Schmidt. Schmidt and Whelan studied nest predation of American robins and wood thrushes in a 500-acre deciduous woodland preserve near Chicago for six years. There, non-native shrubs have largely replaced the native shrubs where the songbirds once nested: honeysuckle has replaced arrowwood and buckthorn has replaced hawthorn. Schmidt and Whelan found that predation of both robin and thrush nests was higher in the non-native shrubs than in the native shrubs and trees. The researchers suggest that this increase is partly due to physical differences between the native and non-native shrubs. Buckthorn lacks hawthorn's sharp thorns, which could deter mammalian predators. Honeysuckle has sturdier branches, which could both help predators climb higher and support nests closer to the ground, where they are more accessible to predators. Wood thrushes built about half their nests in exotic shrubs. During the study period, the number of robins nesting in honeysuckle increased six-fold (from 5% to more than 30%). The researchers suggest that honeysuckle is an attractive nesting site because it sometimes leafs out before the native shrubs. The good news is that solving the non-native shrub problem could also help solve the songbird problem. The bad news is that removing exotic shrubs and restoring natives will be a big job. But the longer we wait, the worse the problem will grow. For more information, contact Kenneth Schmidt (901-678-4408, Caracal7@aol.com), or Christopher Whelan (815-476-3134, virens@attglobal.net). PHOTOS in slide format of thrushes and robins nesting in exotic plants are available from Kenneth Schmidt
