Shannon index for visible roadside plants in Grand Anse (St. Georges University Campus)
Data collection was carried out in the St. Georges University Campus. Samples were collected at the top and bottom of the campus. Surveys of only trees and shrubs adjacent or directly visible from the roadside were taken.
This roadside sampling approach was selected for consistency, practicality and safety, allowing for a manageable yet representative assessment of the visible woody plant diversity along the main corridor of the village.
