We examined the recovery of a secondary tropical dry forest using 30 quadrats (20 m 20 m). The objectives of this study were to describe the species composition and stand structure of a secondary tropical dry forest after human disturbance and to assess its recovery. In total 30 species from 16 families were observed in the quadrats. In the 24-year period the tropical dry forest had recovered to 706 ( 99 standard error) individuals ha-1 with an average total height of 4.3 1.5 m and basal area of 2.92 0.51 m2 ha-1. To assess the recovery of the tropical dry forest its diversity measures and structural attributes were compared with the values of an old-growth forest of over 70 years old. Species richness exponential of Shannons index and Fishers recovered by 43 40 and 34 respectively. Stem density average total height and basal area recovered by 57 48 and 14 respectively. The species diversity of the secondary tropical dry forest had potential to increase but might not attain the level of the old-growth forest. However the structure of the secondary tropical dry forest was on the way to the status of the old-growth forest. Long-term conservation or silvicultural interventions would be required for the forest to reach its full recovery.

Abstract

We examined the recovery of a secondary tropical dry forest using 30 quadrats (20 m 20 m). The objectives of this study were to describe the species composition and stand structure of a secondary tropical dry forest after human disturbance and to assess its recovery. In total 30 species from 16 families were observed in the quadrats. In the 24-year period the tropical dry forest had recovered to 706 ( 99 standard error) individuals ha-1 with an average total height of 4.3 1.5 m and basal area of 2.92 0.51 m2 ha-1. To assess the recovery of the tropical dry forest its diversity measures and structural attributes were compared with the values of an old-growth forest of over 70 years old. Species richness exponential of Shannons index and Fishers recovered by 43 40 and 34 respectively. Stem density average total height and basal area recovered by 57 48 and 14 respectively. The species diversity of the secondary tropical dry forest had potential to increase but might not attain the level of the old-growth forest. However the structure of the secondary tropical dry forest was on the way to the status of the old-growth forest. Long-term conservation or silvicultural interventions would be required for the forest to reach its full recovery.
