Bulfo boreus
April 12 road dissecting storemen meadow. The longest pool
of continuous water occurs along 40 yards of the
ditch. Maximum width of pool is 4 feet, max.
depth 4-5 inches to false bottom of matted vegetation.
Some small, shallow (<2" deep) isolated puddles
are present scattered over rather 50-60 yards of
the ditch. Green vegetation and saturated soil at
the bottom of the ditch suggest a drying up of
once continuous, possibly flowing water. No anuran
eyes found, not even Bulfo which should be
dry breeding now. Air temp. 1" above matted surface
surface of meadow at 4 p.m. 22.1° C. Water
temp. 1" below surface in pool 3" deep was
18.9° C.
