NEXT MEETING IN DADE COUNTY

ANNUAL YARD VISIT AND SOCIAL MEETING
Sunday, August 1
(in place of the July meeting at Fairchild)

Time: 4:00 - 6:30 pm (guided yard tour 4:30; potluck dinner 5:30; plant raffle follows dinner).

Who's invited: FNPS members and their families and guests.

Where:  Home of Native Plant Society members in Redland.

Because this meeting is for members and their guests only, the location is included only in the print newsletter mailed to members.  Please join so you can enjoy all the activities of the chapter!

Bring: Pot luck dish (main, side/salad, dessert), lawn chairs or blanket to sit on, mosquito repellant, if desired.  Punch, tea, plates, napkins, cups and utensils will be supplied.

Description: 1½ acres with about half pineland and half hammock.  Also some fruit trees and palms -- it's Florida, you know!  I have plants from 25 years old to present -- I'm always planting!  The pines go from mature to seedling and a lot of them are popping up in my yard now.  I try to plant lots of endangered species.  I also have foster plants from Fairchild's "Connect to Protect" pineland project.  No waterfalls or quicksand, just bird baths, houses, feeders!  I also have occupied purple martin houses and nesting woodpeckers, but they will not be home in August.  There are usually lots of butterflies.  AND the house is for sale!!!  If I can't find a plant person, we will be having a giant plant rescue sometime in the future!

UPCOMING FIELD TRIP

DCFNPS and Miami Blue NABA

If the weather is very bad, please call to confirm.  Field trips are for the study of plants and enjoyment of nature by FNPS members and guests. Collecting is not permitted. Children are welcome. For carpooling, call Patty Phares (305-255-6404).

Saturday, July 24, 2010, The Deering Estate at Cutler in South Miami-Dade.

Time, address and directions are in the print newsletter mailed to members.  Please join to enjoy all the activities of the chapter!

  • Bring/wear: A hat, sunscreen, sturdy shoes, bandanna or hand towel, and plenty of drinking water as the dog days of summer are upon us.  Bring lunch if you wish to picnic at end of hike, or we might find a cool restaurant to enjoy together.
  • Difficulty:  Easy to moderate, walking will be along fire breaks with an occasional jaunt into the woods.
  • Cost:  Free as we will be volunteering to help out the park!
  • Trip Leader:  Steve Woodmansee, Pro Native Consulting (786-488-3101)
  • Info about the park:  www.deeringestate.com

Description: This conservation land was acquired by the Miami-Dade County Environmentally Endangered Lands (EEL) program and Florida 2000 Land Acquisition Program in 1985, with additional property being acquired in subsequent years.  It consists of over 400 acres of pine rockland, rockland hammock, tidal swamp, and salt marsh habitats in addition to Chicken Key, archaeological sites, and historic buildings.  DCFNPS members will assist the Miami Blue Chapter of the North American Butterfly Association (NABA) in identifying some of the rare plants and butterfly host plants found in pine rockland habitat so that they will know them while conducting butterfly surveys.

This is an opportunity to see the largest tract left of coastal pine rockland in the U.S. (over 100 acres), which is home to foxes, gopher tortoises, over 100 bird species, and lots of insects including butterflies.  Some of the rare plants include Florida prairie clover (Dalea carthagenensis var. floridana), Deltoid spurge (Chamaesyce deltoidea), Small's milkwort (Polygala smallii), and Crenulate lead plant (Amorpha herbacea var. crenulata), as well as tons of other wildflowers.  If time permits, we will cool off in the nearby rockland hammock and continue to look for host plants and butterflies.

More field trip thoughts:

After our June field trip, participants suggested a few things they wish they had brought.  These might or might not apply on all trips or to all people (a walking stick is a must for some and a nuisance to others), but consider these suggestions:

  1. Garbage bag to pick up some litter (if you are so inclined).  Every little bit helps.
  2. Bug spray or long sleeved light-weight shirt
  3. Cream for itches
  4. Binoculars and/or loupe for taking a closer look
  5. Walking stick for off-trail use
  6. Tillandsia with specific directions and phone numbers; it's easy to get slightly lost in unfamiliar areas. 

Also, a question we would like to answer:  Why is Camp Matecumbe (now the Pineland Preserve we visited in June, containing the former and Boystown/Pedro Pan children's home) named "Matecumbe"?  If you know, please contact the editor.

There is also an event on September 25 in Doral.

Here is some information about two of these native trees from The Institute for Regional Conservation's "Natives For Your Neighborhood."  See www.regionalconservation.org for more details about all the native trees available.

Inkwood: The IRC describes inkwood as "An attractive medium tree with dense foliage maintained close to the ground for many years. The wood is very hard, heavy, and durable and much used for crafts and construction. The bark and berries are used to make a homemade ink-like substance in the West Indies." It is a canopy or subcanopy tree in hammocks and is tolerant of short droughts.  It has a dense crown of shiny, compound leaves and semi-showy, fragrant white flowers with an orange disk in the middle.  They are dioecious, but some trees have a few flowers of both sexes or bisexual flowers.  Females produce berries which ripen to dark purple and are good bird food.

Orange geiger:  This tree's native range in South Florida includes only the Florida Keys and the extreme southern mainland, mostly in Everglades National Park.  It is widely planted outside its natural range and sometimes naturalizes, so it is not appropriate for restoration or near most natural areas.  That said, it is a drought-toleran, small tree with bright orange flowers that provide nectar to some butterflies.  [Editor's note: The foliage is periodically damaged by the larvae of the geiger tortoise beetle.]

OUR BEST BIRD-ATTRACTING NATIVES

By Roger L. Hammer

Through a grant, Audubon of Florida spearheaded a project last fall, which was led by ornithologist John Ogden, to not only identify which native trees attract birds, but exactly which birds they attract, and why. It is called the Bird Oases Project. Observers, including myself, went into the field once a week through the fall 2009 and spring 2010 migrations to tally the number of birds observed, and to record what those birds were doing. Targeted birds were migratory species, which included many species of warblers, vireos, and flycatchers. Two sites that were monitored weekly were Matheson Hammock and the adjacent Fairchild Tropical Botanic Garden in Coral Gables.

At the end of the 2009 fall migration we had a good list of birds and some good data on which native plants were most often used by migratory birds as a source of food. If a bird was simply hopping through the tree canopy in search of insects, then no data was recorded other than the bird sighting. But, if a bird spent time in, say, a particular tree while actively feeding, then that information was recorded. The recorded information included the bird species, the tree species, whether or not the tree was in flower or fruit, and what the bird was observed feeding upon. Interestingly, many birds that we tend to think of as strictly insect-eaters were not only observed eating insects, but also feeding on fruits and even flowers.

Even more interesting was the identity of the tree that had the most feeding activity recorded during the field studies, and that tree was soldierwood (Colubrina elliptica), which has a natural range in Florida that only includes the Upper Florida Keys, most particularly Key Largo and Elliott Key in Biscayne National Park. Because this tree is seldom seen in cultivation, we are now encouraging local native plant nurseries to begin growing soldierwood in order to offer it to the general public, thereby offering migratory birds a favored food source. The small green flowers of soldierwood produce an abundance of nectar, which attracts insects, which, in turn, attract insect-eating migratory birds like warblers, vireos, gnatcatchers, and flycatchers. Soldierwood trees observed during the study were located at Fairchild Tropical Botanic Garden and a tree cultivated in John Ogden's yard, which had more than a dozen different warbler species in it at one time.

Other Florida native plants that made the list of species that attracted the largest numbers of migratory birds were (in alphabetical order by genus/species):

Gumbo-limbo (Bursera simaruba)
Satinleaf (Chrysophyllum oliviforme)
Strangler fig (Ficus aurea)
Shortleaf fig (Ficus citrifolia)
Florida privet (Forestiera segregata)
Wild tamarind (Lysiloma latisiliquum)
Lancewood (Ocotea coriacea)
Live oak (Quercus virginiana)
False mastic (Sideroxylon foetidissimum)
Paradise tree (Simarouba glauca)
Chiggery grapes (Tournefortia hirsutissima)
Florida trema (Trema micranthum)

Of those species, it was false mastic and satinleaf that had the highest recorded bird activity, with birds observed feeding on insects as well as the fruits and nectar-filled flowers. Both trees are in the Sapodilla Family. In fact, members of the Sapodilla Family Sapotaceae) proved to be big favorites of birds, including the exotic mamey sapote (Pouteria sapota), native to Mexico and Central America but cultivated in South Florida for its delicious fruits. It stands to reason that our native wild dilly (Manilkara jaimiqui subsp. emarginata) would be a good bird-attracting tree to cultivate as well.

This project will hopefully encourage the wider dissemination of these species for South Florida gardeners and bird lovers alike.

[Editor's note: Concerning dioecious trees and shrubs like Florida privet, paradise tree, Florida trema, Roger adds: "Yes, both male and female trees were attracting birds, although the most activity was on female fruiting trees, especially the privet."]

FOLLOWUP RECOMMENDATIONS FOR COTTON SEED BUG CONTAINMENT

In the May 2010 Tillandsia, the article "New Pest Found in Wild Cotton" requested that wild cotton plants being removed from yards be double-bagged before placing in the trash to prevent possible spread of the cotton seed bug (see past newsletters). This is especially important for Keys residents since the bug has been found in Stock Island and now Key West, and Monroe County trash is trucked to Broward County.

Here is an updated recommendation provided by Julieta Brambila (Entomologist, USDA Animal and Plant Health Inspection Service, Plant Protection and Quarantine):
 
If you think your plants might be infested with the cotton seed bug, the Division of Plant Industry of the Florida Dept. of Agriculture and Consumer Services asks Monroe County residents to please call 352-372-3505 ext. 185 or 438 so DPI can come verify and document the infestation and remove the plant for you. Or write to L. Whilby at whilbyl@doacs.state.fl.us.  
 
If the plants are not infested, then dispose of the bagged plant in the trash. For now, the county waste management in the Keys (and in other counties) tells homeowners not to bag yard trash delivered to the transfer stations, so please dispose of a bagged (presumed uninfested) plant in the regular trash pickup.
