Secondary succession occurs on areas that previously supported vegetation but where the original plants have been removed by events like fire, farming, or other causes. It involves the progression of plant communities over time until a climax community is established. Halosere describes secondary succession that begins in saline environments like salt marshes, starting with pioneer species like algae and grass, followed by shrubs that can tolerate salt, and eventually reaching a climax community adapted to the saline soil conditions. The document provides the example of Alnmouth salt marsh in Northumberland, England, which was initially colonized by algae and eelgrass and now contains salt-tolerant plants.

2. Secondary Succession
or Plagio Climax
The progression of plant communities occurring on areas
where there has been previous vegetation (destroyed by
fire, farming, or other).

3. •Tropical Rain Forest
The forest "creates" the
rainfall through the process of
transpiration. When the trees are
removed, the rainfall stops. The
land then becomes arid. The
resulting new climax community
is often desert shrubs
•Abandoned Farms
Examples

4. Halosere
The series of communities succeeding one
another, from the pioneer stage to the
climax, and commencing in salt water or on
saline soil.

5. Examples
•Alnmouth, Northumberland
Alnmouth is a village located at the mouth of
the River Aln on the Northumberland Coast.
First colonized by green algae and eelgrass, contains
halophytes
It is considered to be
the largest salt marsh
in Eastern England
