This is a basic datasheet which is meant to be used as a guide to building a datasheet for any biodiversity measurement study. You should add more fields depending on the requirement and aims of the study but do not omit any fields as all the fields presented here are for measuring biodiversity and all the indices associated with this.

This datasheet can be copied and pasted into a new document and printed out to save time.

An Explanation of the Data Sheet.

Fields -

Serial No. Of the Unit of Sampling – A sampling unit can be thought of as a standardised unit of measurement in which samples are obtained when sampling. Thus the sampling unit would quadrats, transects etc. Which are standard sampling units used when sampling for biodiversity. The sampling unit should be selected based on the group of organisms being studied. (Click here(Coming soon) for more information on selecting a sampling unit for your study).

Species – In this field the name of the species (or an arbitrary name used to designate the species if it is unidentified) found in each sampling unit should be noted.

Number of Individuals – In this field, the number of individuals of each species found should be noted. Using tally marks to count makes it easier if the sampling unit is large.

After filling out the data sheet in the field while sampling, the data should be entered into a computer, preferably in a format such as an excel spreadsheet. The data can then be analysed with various softwares to produce indices and statistical treatments that will lead to insight into the measure of biodiversity of the area and other interesting results associated with the data.
