"Pruning Landscape Trees for Tree Health and Safety" --

George Fitzpatrick, Professor of Environmental Horticulture, University of Florida.

Just in time for pre- and post-hurricane season tree care, this program will focus on the objectives for landscape tree pruning, with emphasis on tree health and safety.  The care and correct use of basic pruning equipment will be demonstrated, and the three major types of pruning cuts, reduction cuts, removal cuts and heading cuts will be illustrated.  Even if you are not going to prune your own trees, learning the basics will help you discuss work to be done when you hire a professional. Dr. Fitzpatrick  teaches at UF's Agriculture Research and Education Centers in Ft. Lauderdale and Homestead and has presented "Training and Pruning of Young Trees" several times at Native Plant Day to appreciative audiences. 

We will also have our brief Annual Meeting of the Dade Chapter where we will elect new chapter board members.

Refreshments are available for early arrivals at 7:15.  Additions to the refreshment table and raffle plant donations are always welcome.  (Please check your plants for lobate lac scale.)  If you signed up to bring refreshments and have questions, please call Patty Harris at 305-262-3763.

June 27: "Aquatic and Wetland Wildflowers of Southern Florida" – Chuck McCartney.

July (probably the usual meeting night): Annual evening yard visit and social.

GOATSFOOT – PASSIFLORA SEXFLORA

by Jennifer Possley,
Fairchild Tropical Botanic Garden

Preview of photo of goatsfoot

Passiflora sexflora, or "goatsfoot," is a Florida endangered passionvine that can pride itself on having an attention-getting name.  While Passiflora refers to the taxonomic genus of which this vine is a member, you might imagine sexflora comes from the titillating twist of its tendrils or an aphrodisiac quality in its flowers.  But, according to Roger Hammer, the explanation is far more mundane.  Sexflora comes from the mistaken idea that members of the species always have 6 flowers.  While this was true of the original specimen that was described, not all individuals exhibit this character. 

Goatsfoot is a beautiful plant that can remain small, but under the right conditions may grow rapidly to clamber over other vegetation and cover several square meters.  Its 3-lobed leaves (which look more like bats to me than goat feet) are softly fuzzy, and often much wider than they are long, a rare characteristic in the world of plants.  They are similar to leaves of the pale passionflower, Passiflora pallens, but much hairier and the lobes are more pointed.  Goatsfoot blooms in December and January.  The flowers are no bigger than a quarter and similar in appearance to corkystem passionflowers (Passiflora suberosa) but goatsfoot has intensely purple filaments.

Around the world, goatsfoot is found in the West Indies and tropical Americas.  In the U.S., however, its entire distribution is limited to a handful of hammocks in Miami-Dade County.  Even within hammocks, goatsfoot is further restricted to partially sunny areas, so it only grows along hammock edges and in gaps created by treefalls.  Hurricane Wilma created a surplus of good goatsfoot habitat last October.  Since I monitor all known individuals of goatsfoot on Miami-Dade parks, I am hoping I will see an increase in number of individuals in response to the disturbance!

To prepare for a June 2006 outplanting, I have been growing dozens of goatsfoot plants in Fairchild's nursery over the past year.  They do not trellis well, so I prune them back every 2 months to prevent tangling.  In response, the plants send out branches from the root stock, making a bushier vine that is stronger at the base.  These plants were grown from cuttings I collected from the wild with Cristina Rodriguez from Miami-Dade County, Emilie Verdon from The Institute for Regional Conservation, and others.  We chose to collect vegetative cuttings as opposed to fruit because they can be taken at any time of year.  We must have a series of stringent permits from several agencies in order to do this collecting. 

If you would like to help with our June outplanting, we definitely need you

ENDANGERED BISCAYNE PRICKLY-ASH (ZANTHOXYLUM CORIACEUM) TREES REINTRODUCED TO MIAMI BEACH

by Sam Wright,
Fairchild Tropical Botanic Garden

Much of Miami Beach was a mangrove jungle in 1915 when John Kunkel Small and Charles A. Mosier first collected Biscayne Prickly-Ash (Zanthoxylum coriaceum) on the barrier island.  They would hardly recognize today's Miami Beach, which at the time was known as Ocean Beach. The land booms of the 1920s and the 1950s caused Miami Beach's economy to grow and flourish. However, to compensate for the land booms, much of Miami Beach was cleared of natural vegetation and areas were filled with spoil material dredged from the bay. The clearing of vegetation on Miami Beach led to the local extirpation of many species of flora and fauna including rare plants such as Biscayne Prickly-Ash. Now listed as a state endangered tree, the primary threats to Biscayne Prickly-Ash include habitat destruction and fragmentation of maritime hammock habitat. Maritime hammock is virtually non-existent now on Miami Beach.

On March 18, 2006 Fairchild Tropical Botanic Garden staff and volunteers from Hands on Miami reintroduced 31 Biscayne Prickly-Ash trees to Miami Beach. Recovery plans for rare plants such as Biscayne Prickly-Ash include increasing the number of self sustaining populations within its historical range. North Shore Open Space Park in North Beach was selected as a reintroduction site because of its intact maritime hammock. The park is also within close proximity to the specimen collected by Small and Mosier in 1915 on "sand dunes opposite Lemon City (present day Little Haiti)" (Gann et. al 2002). Although the mangrove jungle of Miami Beach has been replaced by a concrete jungle, North Shore Open Space Park remains a green oasis within the urban landscape. Currently, City of Miami Beach proposed plans for the park include preserving the remaining hammock as a natural area, which would give the Biscayne Prickly-Ash a safe home for years to come.

HISTORY OF PINE RIDGE SANCTUARY

by Terry Glancy

Over 30 years ago, my wife, Barbara, and I started one of the first plant stores in Michigan as an expansion of the weekend hobby of plant maintenance for homes and offices in the Detroit area.  I worked in a lab for viral oncology and Barbara was going to college at the Center for Creative Studies College of Art and Design.

Several times a year, we would drive to South Florida to buy plant material for the store. During one of these trips, Barbara started to look for property to buy in Dade County to start a plant nursery.  She would climb through everything from overgrown abandoned scarified land to what would turn out to be poisonwood hammocks on pinnacle rock.

Eventually she came across a 10 acre piece of degraded pineland belonging to the widow of Roland T. Bird, one of the last true "dinosaur hunters" in North America, along with a 5 acre piece next to Mrs. Bird's.  Both pieces of pineland had been purchased from the Florida East Coast Railroad in the 1940s and had never been rock plowed like all the rest of the pinelands around here.  Barbara investigated everything before we purchased the property, including purchasing aerials of the Section (1 mile square).  The aerials clearly showed property nestled between two fairly major sloughs (part of Taylor Sough) which meant we were high and dry and any flood waters would drain into the finger sloughs.  It also meant that farmers had never planted on our pineland and harvesting of pines for fence posts was minimal.  DOF determined that the average age of the pines were between 85 and 125 years old.

We purchased the 15 acres in 1976 and started to remove the exotics like Schinus, Casuarina, Albizzia and mangos.  In February 1979 we started prescribe burning with the DOF.  Barbara called the Dade County Urban Forester and introduced herself. This is funny: Richard Bailey, the Urban Forester, answered the phone call with "Who are you and how did you get my phone number? Yes, my job is to act as liaison between private land owners and the Forestry service, but I have never had anyone call me."  He was happy to finally be able to work with forest owners!

The first prescribed burn was a training exercise involving all the foresters in South Florida.  Back then, there was one forester for the Everglades, one for Ocala National Forest, etc, but they never had the opportunity to work together.  We had to drive up from Key West the morning of the burn, but before we arrived we could see the smoke plume from Marathon!  The property had never been prescribed burned, and the Birds, who lived in pup tents on the property when they were not finding dinosaur tracks in the Paluxy River in Texas, were afraid of fire.

In 1987 we started Pine Ridge Orchids, Inc. as a wholesale commercial orchid nursery. The nursery was located on a disturbed portion of the pineland and we built our home in 1988 in the middle of the pineland in an area where the Birds camped and kept their cow.  Not a single Pinus elliottii var. densa was lost or disturbed in the building of the house.

We were one of the first properties to enter into covenant with Miami-Dade County with Chapter 25B in 1983.  In 1989 we became a Registered Property with The Nature Conservancy and in 1991 we became the first Forest Stewardship Property south of Lake Okeechobee.  That year our property was the "over-all" winner for the FNPS Landscape Enhancement Awards - the first time a property was awarded both for Residential and Commercial categories.

Hurricane Andrew in 1992 and the ensuing IPS beetles killed about 3,500 of our pines.  A beetle monitoring stations was set up by Fairchild Tropical Garden, Montgomery Foundation and DOF.  Each station was a large tub with a black painted metal exhaust pipe in the middle (simulating a burned pine tree trunk), surrounded by soapy water. A wick emitted a scent of ethanol and turpentine to bait insects.  Once a week we drained the tubs and filtered out thousands of dead insects for identification. The stations clearly showed the dramatic increase of IPS beetle population after the hurricane damaged the pineland.  The population of IPS predators did not build up to a high enough population for several months, but by then the pines were dead. An Old World beetle that had never been reported in North America before was also discovered – blown in from Africa during Andrew?

We started to replant pine "tublings" in 1993 after the IPS beetles died out.  In 1997 we won the Forest of the Year award for the entire State of Florida presented by the Forest Stewardship program sponsored by FL DOF, FL Game & Fresh Water Fish Commission, The Nature Conservancy, USDA Soil Conservation Service, UF IFAS, Florida Forestry Association, and the Florida Cooperative Extension Service.

On December 27, 2000, a negligent farmer who was cutting down a windbreak structure nearby started a fire that spread and burned our entire property and caused massive damage to our commercial orchid nursery. The burn actually was a very beneficial ecological burn, even though it occurred in December during the worst draught in Florida history and caused mortality to mid-level plants including pine tublings that we had planted over the previous 8 years, silver palms over 100 years old, saw palmettos, and large cabbage palms – plants that had easily survived all past prescribed burns.  The wildfire burned the entire 15 acres and jumped SW 300 Street and burned portions of the neighbor's pineland in less than 20 minutes. Barbara, our son, Christopher, his girlfriend, and a good neighbor saved our home using garden hoses and buckets of water from our pool.  Three employees and a neighbor helped me with garden hoses around the greenhouses and the 3000 gallon propane tanks. The back of the greenhouses melted, but the main damage was to the orchids that died during the two months of smoldering due to all the ethylene and carbon monoxide gasses and the thousands of volatile chemicals that were deposited on the flowering plants. The oolitic limestone rock was so dry due to the extended draught that the snags that were still standing 8 years after Andrew were smoldering and the root systems were burning like giant underground cigarettes. It was like living in a 15 acre dirty ashtray for four months.   But if we had not been maintaining and burning since 1979, we would have certainly lost our home and business.

The upcoming FNPS tour will be interesting because prescribed burns were held on the western 5 acres on August 12, 2005, and on the middle and eastern 10 acres on December 5.  You will see the pine rockland regrowth from two prescribed burns occurring in the same year on the same piece of property. The "maintenance stage" of forest restoration on this rockridge pineland, one of the most globally endangered ecosystems in the world, is on-going.
