Measure vegetation
diversity by throwing the
quadrant to your feet
randomly, and counting the
Number of different plant specie
in the quadrat – in a sparse area to
represent where there are human
encroachments and a dense area
to represent where there have not
been human encroachments
Vegetation coverage/density
will be recoded by
eyeballing and
estimating the %
coverage on a sparsely
and a densely vegetated
area.
To measure the height of vegetation
measure the highest piece of
vegetation from the center square
of the quadrat and record its height
in cm using a small ruler

(A) The Vegetation Site
Infiltration rates: Vegetated area
Put 5 centimeters of water in the infiltrometer and time how long it takes
to infiltrate into the soil on a dense and sparsely vegetated area. The dense area
represents an area without human encroachments & the sparse area
represents and are where they have been human encroachments.

To find out the
average infiltration
rate of your soil
divide the total time taken,
by 5 this will give you
the average rate in cm per
second
