Title: What is Pond and Forest Succession
1What is Pond and Forest Succession?
2Ponds 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
4Life of a Pond
5When 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.
6The first set of animals to come to a pond and
bring seeds are called POND PIONEERS.
7As more and more animals and arrive, more plants
begin to grow and the debris on the bottom of the
pond begins to build up.
8As more and more plants begin to grow, more
insects begin to come to the pond ecosystem.
9Pondweed begins to grow along the bottom of the
pond.
10Emergent plants begin to grow out of the water at
the edges of the pond.
11Over 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.
12Once the pond becomes shallow enough, emergent
plants begin to grow all the way across the floor
of the pond.
13When 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.
14The marsh continues to fill in with dirt and
debris from decomposed organisms. Trees begin to
grow in the water.
15At this point the marsh becomes a swamp. The
swamp may dry out over time. It can then become
a forest or grassland.
