Title: What is Pond and Forest Succession


1
What is Pond and Forest Succession?
2
Ponds and forest change throughout time. This is
called succession.
3
  • Succession can be defined as
  • the gradual and orderly process of change in an
    ecosystem brought about by the progressive
    replacement of one community by another until a
    stable climax is established

Life of a Pond
5
When a pond is first developing, there is little
more than water that has collected in an area.
Over time, birds and land animals come to the
pond as a source of water. When they come to the
pond, they carry seeds with them which are then
dropped into the pond.
6
The first set of animals to come to a pond and
bring seeds are called POND PIONEERS.
7
As more and more animals and arrive, more plants
begin to grow and the debris on the bottom of the
pond begins to build up.
8
As more and more plants begin to grow, more
insects begin to come to the pond ecosystem.
9
Pondweed begins to grow along the bottom of the
pond.
10
Emergent plants begin to grow out of the water at
the edges of the pond.
11
Over hundreds of years, plants and animals die
and decompose piling on the floor of the pond.
This raises the pond floor up and causes it to
become shallower.
12
Once the pond becomes shallow enough, emergent
plants begin to grow all the way across the floor
of the pond.
13
When these plants begin to grow throughout the
entire pond, a marsh begins to form. So a pond
can turn into a completely different ecosystem,
but it takes hundreds of years to do so.

14
The marsh continues to fill in with dirt and
debris from decomposed organisms. Trees begin to
grow in the water.
15
At this point the marsh becomes a swamp. The
swamp may dry out over time. It can then become
a forest or grassland.
