A Seven-Year-Old Ocala Sand Pine Seedling Seed Orchard
A 20 acre Ocala sand pine seedling seed orchard was established in 1978 near Ocala, Florida. First year survival was 67%. An apparent adaptive mechanism that allows some trees to survive unfavorable environmental conditions was noted. After 7 years and 2 thinnings, the tallest trees were over 26 ft. and the tallest family averaged over 19 ft. Although a few cones were observed after 3 years, the orchard is just starting to produce a significant amount of seed.
