Abstract

In this study, I specifically looked at three major issues regarding 36 target plant species in a fragmented landscape in the Corozal district, Belize: 1) Determine woodlot characteristics that tend to favor the target species. 2) Determine plant characteristics that tend to favor the target species. 3) Determine whether age and size of a woodlot favors the presence of the target species. The study area was divided into three areas and each area had woodlots varying in sizes and ages. 36 plant species were sampled in all woodlots upon which woodlot characteristics and species characteristics were associated with the number and frequency of these plants. Data was analyzed using Correlation techniques, Stepwise Regression analysis and Detrended Correspondence analysis. Woodlot and species characteristics seem to be confounding. Woodlot characteristics that yielded greater species richness for the correlation and regression techniques are older, larger, closer to Shipstern Nature Reserve, farther from sugar cane fields and farther away from papaya fields. Woodlots that are older, closer to Shipstern Nature reserve and farther away from papaya fields had higher Axis 1 values for DECORANA. Species were more widespread when they were insect pollinated for the correlations and regression analysis. Species had higher Axis 1 values if they were insect pollinated and higher Axis 2 values if they are perennials. Over all, our data suggest that the Copper Bank area is more species rich because the woodlot and species variables accounted seem to favor the presence of more of the target species in this area, whereas these properties of woodlots are lacking in the other two areas namely San Narciso and Santa Elena.
