Boca Grande Banyan Allée
By David Driapsa
David Driapsa conducted a Historic American Landscapes  Survey of the century-old Banyan tree (Ficus benghalensis) allée in the town of  Boca Grande on Gasprilla Island in SW Florida. David’s team included fellow  landscape architects Elena Pascarella and Bill Lutrick. Elena worked with David  to measure and record the trees. Bill is a large format photographer working closely with  David to record his projects in photographs. David works with the National Park Service to  enter his documentation into the Library of Congress.
  
The Boca Grande Banyan allée is one city-block long and originally consisted of  26 trees, with 13 planted on each side of the street 25 feet on center and 38  feet apart across the street. Twenty-one trees remain, including two small trees  replanted following damage caused by hurricanes. 
The Cultural Landscape Foundation featured these Banyan trees as landmarks in  Landslide 2007: Heroes of Horticulture. 
These trees are a historic landscape feature remaining from the early  development of Boca Grande. Documentation has not revealed who planted the trees  or when. Landscape architect Carl Rust Parker prepared a master plan in 1914  proposing the planting of street tees to help transition the gritty railroad  town to an island resort for the wealthy. At that time, employees of Boca  Grande Land Company planted palm and tree allées of differing species along the  streets of Boca Grande. It is likely that these Banyan trees were planted as  part of that project. Photographs made for the Olmsted Brothers Landscape  Architects in 1925 show another Boca Grande street that was lined with these  so-called rubber trees. Those trees are no longer extant.
Banyan trees create a massive canopy of foliage. For example, the Banyan tree  in Fort Myers at the Thomas Edison Winter Estate, planted in 1925, is 300 feet  in diameter.  These trees produce aerial  roots from the limbs and grow down to the ground forming stilt-like trunks that  support the ever increasing weight of limbs as the tree grows larger. 
Hurricanes, tropical storms, and street flooding have impaired the Boca Grande Banyan  tree allée. Heavy trimming to repair damage caused by hurricanes has resulted  in internal rotting of the trunks beginning at the pruning cuts. Annual  structural pruning and removal of aerial roots has rendered large limbs unsupported  by new trunks to carry the weight of the canopy. 
The Banyan tree allée on Banyan Street in Boca Grande stands mostly intact as a  reminder of resort town development during the late pioneer era of SW Florida.  Will the trees survive as an allée for another century? HALS documentation  preserves a record and raises an awareness of this significant historic feature  of the cultural landscape.
