Succession: Time For A Change
In front of you is an area that humans have
affected by mowing. Mowing has stopped and now nature is beginning to
change the landscape. The first plants to spring up are those requiring
ample sunlight. Other plants will grow up in the shade created by these
first plants. Eventually, these shade-tolerant plants will replace those
needing more sun and begin creating a maritime forest. This shift from
one plant community to the next is called succession.
Pass the Salt!
Coastal
plants have adapted to severe conditions. The salt in the wind, soil,
and rain will kill less-tolerant plants. Notice how stiff the bayberry
leaves are. A natural coating on the leaves protects the bayberry from
salt. As you get further from the coast, fewer salt-tolerant plants are
found.
Clearings: Nature’s Skylights
You
have traveled from an area of young shrubs into an established maritime
forest. This part of the pinelands is in a later stage of succession and
so has older trees and shade-tolerant plants. Ahead is a clearing. Clearings
are created when a tree falls, leaving an opening in the canopy overhead.
This opening allows sunlight to penetrate to the forest floor. The result
is a return to the earliest stages of succession. Can you see examples
here of plants found at Stop 1?
