. The Caribbean forester. Forests and forestry Caribbean Area Periodicals; Forests and forestry Tropics Periodicals. 70 Caribbean Forester. Figure 6. - Sprouts of white mangrove 5 years old, showing typical leaning of lower stems. 10. Thinning a plot in the large sapling stand to a residual basal area of 60 square feet per acre tripled mean growth during the subsequent 4 years. In a plot in the pole stand a similar thinning doubled mean growth during the following 3 years. These in- creases arose from two sources: (a) the elimination of slow-growing trees and (b) the acceleration of the growth rate of those remaining. This acceleration was produced in part by an upward shift in the position of the remaining tree crowns in the canopy, but was also significant in trees where no marked change in crown position took place. 11. No serious windthrow losses were suf- fered as a result of the thinnings made. 12. The thinings made did not induce ef- fective natural regeneration of any species. 13. Adequate natural regeneration of white mangrove appeared within 2 years on strips 66 feet wide clearcut perpendic- ular to the wind in the pole stand. 14. Wind damage along the edge of the clearcut strips was no greater than elsewhere in the pole stand. 15. A 5-year-old sapling stand on the area regenerated after clearcutting suffered negligible damage in a hurricane which destroyed 59 percent of the trees in the adjacent pole stand. 16. Evidence of water-borne seed of white mangrove in the clearcut strips indi- cates that regeneration might be equally prompt on larger clearcut areas. 17. Naturally regenerated white mangrove 9 years after clearcutting in strips at- tained an average of inches (maximum inches), a canopy height.
