Professor Roger Byrne, Department of Geography, University of California, Berkeley

DISC Source:

Date of Study or Data Collection:
1972

Universe to which Data Pertain:
Woodland of Cat Island, Bahamas

Sample Description:
Three hundred sampling sites were established. In each, an estimate of the cover was made in 25 by 1 meter square quadrants. In total, 124 woody species were encountered. Each sampling site was unambiguously located on aerial photographs (1:12,500) and classified according to age of vegetation, height of vegetation, substrate, soil, drainage, and distance from the nearest settlement.

Number of Data Units:
300 (number of data cards per observation varies according to the number of species found in the quadrant)

Mode of Data Storage:
Cards (varies per observation)

Reference Materials:
Codebook; abstract of dissertation reporting results of analysis of the data

Condition of Data:
As received from Professor Byrne

Abstract of Content:
The subject of the dissertation which produced these data was an analysis of the extent to which man modified the woodland of Cat Island, a small island in the Bahamas. The methods employed in the research were basically of two kinds: analysis of historical evidence for vegetation change, and analysis of the contemporary vegetation. The data file contains variables relating to a description of the woodland specie(s) found on the old field: age class, habitat type, height class, soil type, moisture class, distance class, and area covered by specie.
