El Verde Coffee Plantation permanent plot vegetation sampling

Research Sites:

El Verde Town Estrada family land

Methods:

Twenty five (2 m X 5 m) plots have been set in the coffee plantation next to the forest. These are organized in five rows with five plots each set up with the 5 m side along the forest edge. The percentage of the area of each plot covered by each species is visually estimated (file 1). For each tree stem in each plot greater than 1 m in height, we measure the basal diameter and height, and identify the species.

Abstract

Permanent plot data is expected to show (1) rapid increases in percent cover and tree stem density, and (2) rapid turnover from early to late successional plant species. Plant-plant competition indices should show quick increases in intensity with exotics as top competitors which may lead to exclusion of some trees common after landslide and pasture disturbance. Spatial patterns of invading trees should include edge effects due to dispersal limitation with clumping of bird-dispersed species before the first five years. Because of increased nitrogen levels due to plantings of Inga Sp. with coffee, trees should grow, as measured by biomass (productivity), height and basal diameter increases, significantly faster compared to landslide.
