ENTS,
There has been some discussion ecently about the early forests of
northeastern United States. One messaged pondered what teh forests
would have looked like prior to the arrival of the native Americans
in the region. (This is in regard to the idea that they used fire to
clear areas of the landscape.) Prior to the arrival of natie
Americans in the northeast, there were no forests. The area was
covered by continental glaciers and tundra. There is a campsite at
Meadowcroft shelter near Pittsburgh that contains a campsite dating
from 16, 000 years ago, prior to the retreat of the last glacier.
Also discussed is how the forest appeared prior to the end of the
1800's and early 1900's when essentially the entier northeast was
clearcut for timber. There are few good descriptions of teh forest
and few photographs prior to that time. One resource worth
considereing are landscape paintings and drawing from the mid 1800's
and earlier. Many of these artists were consumed with maing an
accurate rendering. http://www.tfaoi.com/articles/subjects/19land.htm
On close-ups of tree it is often easy to distinguish species based
upon bark pattern and limb structure. On broader views of teh
landscape it may be possible to distinguish certain species by size
and form.
One movemnet around the mid 1800's was the Hudson River School. http://www.tfaoi.com/aa/6aa/6aa4.htm
The Hudson River School emerged during the second quarter of the
19th-century in New York City, the booming port and commercial
metropolis at the mouth of the Hudson River. There, a loosely knit
group of artists, together with like-minded poets and writers,
forged the first self-consciously "American" landscape
vision and literary voice. That American vision -- still widely
embraced today -- was grounded in the exploration of the natural
world as a source of spiritual renewal and as an expression of
national identity; this vision was first expressed through the
magnificent historic scenery of the Hudson River Valley region,
including the Catskills, accessible to all via the great river that
gave the school its name. Collectively, the works of Hudson River
School artists constituted the nation's first homegrown art to not
only take root in this country, but also to garner world-wide
recognition and fame. (left: George Henry Boughton (1833-1905),

I think this may something worth pursuing concerning the history of
American forests. perhaps even an article in some Art Journal. There
is a book about the movement available from Amazon (Search through

Ed,
Thanks for the links. I do have something to add, none of which is
probably news to you though:
Prior to the arrival of Native Americans in the Northeast, there had
been forests there. Certainly during most of the Pleistocene the
region was covered by ice and tundra, however, the mesic forests of
Eastern North America have certainly been advancing and retreating
for
millions of years, and many of the species we know today, and
certainly there ancestors were around at that time.
It's facinating to think about the forest composition of the
landscape
temporally. Spruce forests in the Gulf Coastal plain, mixed
mesophytic forests along the Rio Grand, the forests moving up and
down
river corridors and mountain ranges. Facinating stuff. In this time
of rapid climate change, the conservation work that we are involved
with is incalculably valueable to the extent that it allows species
to
continue to utilize these ancient migration corridors.

Josh,
yes teh glaciers advanced and retreated across the northern United
States many times in the last million years. The forests would reach
northward during the comparatively breif 10,000 -20,000 year
interglacial periods and then be wiped out by the advancing ice
sheets and the cold during the longer 100,000 glacial advances. The
last retreat dates from about 10,000 years ago and the forest have
again pshed northward along with the populations of this time of
native Americans.

Hi all,
I repeat me recommendation of a good book on the subject of trees
returning to at least SE US after the glaciers, only this time with
more
exact information:
Forests in Peril: Tracking Deciduous Trees from Ice-Age Refuges into
the
Greenhouse World (Paperback)

Elisa,
I read an online review of that book several months ago.. I would
like to follow up and read the rest. The theme of what I read was:
the river corridors of the Southeast have been essential to the
maintenance of diversity throughout the recent glaciations, and now
that most are impounded several times, and because of the numerous
other forms of fragmentation across the landscape, it will be
necessary to transplate certain species northward in this warming
event to avoid thier extinction.
Thanks for the recommendation,
Josh
