Since the Samaru plantation is the smallest, its size was chosen as the
standard area where assessments were made in all sites. In each of the other
plantations and their adjoining fallow lands, an area of the same size was
chosen, avoiding large gaps created by fallen trees, which otherwise, would
encourage localised typical growth of herbs.
Abundance of grasses and dicotyledonous herbs (excluding coppices of
non-forage tree species) were assessed using a 2 m by 2 m quadrat randomly
replicated four times along transects in the direction of any observed
changes in herbage cover [Williams and Lambert, 1959].
Percentages of light intensity reaching the plantation floors were
measured at about l l00h using a Kahlsico light meter (Kahl Scientific
Corporation, California, USA) at four random points (two at any sunflecked
and two others at any shaded spots) and compared with that in the
adjoining open, fallow savanna forest reserve grasslands (full light).
