different times and under different weather
conditions. Temperatures at different heights
in the woods, plus min./max., day/night
temperatures would also have been of
interest. However, on each of the four visits
the even sunshine enabled direct site
comparisons to be made and illus-
trated the effects on the habitat. For
example, when the sunlight was interrupted by
the dense canopy of Area 1, the ambient
temperature was consistently lower than Area 2,
and that with its moderate canopy cover, lower
than the open area in Area 4. Notably the
wind chill was limited on these visits, but at
night the woodlands would be expected to hold
heat longer than the open community in the
autumn and winter. When the tree canopies were
greatly reduced the differences were similarly
reduced. Water temperatures at site 3 were
taken at a depth of approximately 9 inches and
some 2 feet from the edge.
