Although palynological studies do have inherent problems which may
confuse results, the consistency of profiles from the region does allow some
statements about vegetational and climatic history. These must be tempered
with the fact thai the entire region has not been tested and differences at the
microscale and semj·microscale levels are probable in view of the diverse
environments in the region.
Based upon the palynological data, it appears that some climatic change
took place c. 3400 B.P.• the approximate time of the decline of the Susquehanna
Tradition. There appears to be a shift to a mild, more moist climate with
reduced productivity. The closed forests may have restricted game movements
in the area, limiting the carrying capacity and, subsequently, population levels.
This condition persisted until the beginning of the Middle Ceramic Period, c.
2000 B.P. At this point, the climate became colder, or there was a shift in
edaphic conditions, resulting in increased productivity despite more severe
conditions.
Maine and New Brunswick provided a diverse environment, rich in resources
for at least part of the transition between the Archaic and Ceramic Periods. This
was a time of possible climatic changes, reflected in the palynological record as
occurring c. 3400 l:lP. The latter of these may have resulted in restricted game
movements in the interior, with the possible consequence of a reduced carrying
