One of the cornerstones of ecological research is measuring and monitoring biodiversity. These measures can be relatively simple to calculate, but often require many hours spent in the field to collect the data. These measures are vital, considering that such information helps to determine the current state of an ecosystem and allows informed management decisions to be made regarding future conservation efforts. Today you will measure species richness (S) , which is defined as the number of different species in a given area. To calculate species richness, you will identify and count trees and plants along a transect within the UCF arboretum. From this information you will calculate the Jost Diversity Index (D), which provides an estimate of biodiversity for that habitat. This index is based on both number and abundance of different species present. Remember to wear protective clothing and appropriate footwear for working in dense brush. Objectives To become familiar with common plant species and communities found in Florida To gain exposure to sampling techniques and experiment design To make measures of biodiversity, including species richness and the Jost Diversity Index Materials The UCF Arboretum Dichotomous key for vascular plants [Note: Pictures (as well as underlined names in the dichotomous key) are provided for the plants that you are most likely to encounter in the Arboretum during your lab] BSC2011 Lab 11 Monitoring Biodiversity

Bsc2011 Lab 11 – Monitoring Biodiversity Background Within the UCF arboretum there are many plant communities represented. We will explore two of the following communities: Pine Flatwoods – once the most dominant plant community in the southeast, this habitat is recognized by the presence of longleaf and slash pines forming a relatively open canopy with saw palmettos and wiregrass in the understory. Freshwater swamps – these are low-lying wet areas that are dominated by cypress, gum, or bay
