Progress Report - November 10, 1987 <br />ESTABLISHMENT OF NATIVE HAMMOCK VEGETATION ON SPOIL <br />1ITES DOMINATED BY AUSTRALIAN PINE <br />Fact Sheet <br />1. In response to a proposal by the Office of Environmental Services <br />of the Florida Game and Fresh Water Fish Commission (GFC), Indian <br />River County provided $2,151.00 from tree ordinance violation fines <br />toward the purchase of tree and shrub seedlings to be planted on <br />three county -owned dredge spoil sites. <br />2. The GFC used this money to purchase approximately 5,000 seedlings <br />from three native plant nurseries. <br />3. The GFC, with the assistance of a work crew supplied by the Indian <br />River Correctional Institute, planted the seedlings from September <br />22-25, 1986. The sites were planted as follows: <br />Round Island - 2 sites, 1 acre and 1/3 acre - 2,059 trees <br />Little Round Island (east of R.I.) - 1 acre - 1,342 trees <br />Wabasso Island - 2 sites, total nearly 3/4 acre - 1,595 trees <br />4. Thirty-one species of trees and shrubs were planted, with a total <br />of 4,996 seedlings on the three sites. From the originally <br />proposed species list, strangler fig was added while marlberry, <br />inkwood, wild coffee, saw palmetto, and yellow elder were <br />unavailable at the time of purchase. <br />5. An experimental planting grid was established on Wabssso Island to <br />allow growth and survival monitoring of a representative sample. <br />Twenty seedlings each of thirty species were planted in the <br />monitoring grid. All other plantings at the three sites were <br />random. <br />6. After one year, the survival rate of the planted seedlings is 69%. <br />When the nine species with less than 50% survival are deleted, the <br />remaining twenty-one species had an 87% survival rate. Growth has <br />been good, especially among those species with high survival rates. <br />7. The GFC's original test planting on a spoil island near Oslo. Road <br />is now 4 -years -old. Survival at that site is 54%, and many trees <br />exceed 4 meters in height. <br />SPECIES CONDITION SUMMARY <br />WABASSO ISLAND HAMMOCK RESTORATION PROJECT <br />SEPTEMBER 1986 — SEPTEMBER 1987 <br />20- 19- <br />18 zo 20 20 so t t 0 o a >o <br />>z <br />>z <br />U <br />u >s n zo 00 <br />7 <br />17- <br />16 to to to <br />16- <br />80 <br />is- <br />5 <br />14 >6 <br />14- <br />70 <br />o, 13- <br />3 12 a <br />12- <br />60 <br />to 11 <br />0 <br />a <br />0 10 t2 <br />9—CDm <br />50 5 <br />E 8 to <br />CL <br />40 <br />z' 7- <br />6 <br />6- <br />5- <br />54 <br />4- <br />s 20 <br />3- <br />2- - <br />4 3 10 <br />1 <br />lie �+� 101 <br />4` Sr V44& , dole 0. <br />t <br />Cly `'Si <br />SOP co'� , i cnL <br />Q�"�aAF JAN fid% y� +W � <br />lt° <br />Healthy Distressed <br />Dead <br />r�eeswe� <br />23 BOOK 70 PACE s® <br />N O 1® .1987 <br />
