is a 360 degree panorama of a second growth forest in
the eastern foothills of the Coast Range, close to Corvallis,
Oregon. Move your cursor onto the center of the picture,
click down and hold it, then drag your icon left or right,
up or down. You can spin around in the forest! Be sure
to look at the "second growth" characteristics:
same-sized trees, a single-layer tree canopy, relatively
few standing snags, and few, small-sized decaying logs
on the forest floor.
is roughly 40-years old. In about 80 years (western Oregon
forests seem to begin to have characteristics of old growth
at over 100 years in age) this forest will begin to have
the characteristics of old growth. Some trees will die,
unable to compete with neighboring trees. These dead trees
will become the snags and downed logs that are characterisitc
of old growth. The remaining trees will conintue to grow
even better now that some of the competition has died!
The open areas in the forest, left after trees died, allow
plants in the understory to develop, creating layers.
