What types of plants are found in coastal wetlands?

Answer 1

A coastal region is an area by the ocean or by the coast of a very large lake. So coastal region plants are found there by the lake or ocean.

If you are asking (it is hard to tell) where coastal region plants grow... well, it depends on the kind of plant, and the kind of coast.

For example, off the coast of Lake Michigan, you will find plants growing everywhere from in tufts on sand dunes, to right up to the edge on dirt based coastal areas. Then there are the rocky areas, where you might find shrubs and small trees clinging to cracks in rock formations, or populating areas where dirt has fallen into depressions in rock faces or collected between them. You can also find small green plants in a scrim on mini islands..

I have even seen plants grow on metal structures erected in the lake itself, where dirt and so forth has collected and created a little green sward of grass and small plants.

It might be easier to say that plants do not grow where the water is too deep or where the action of the waves might disturb them too much, or were flotsam is washed up so often that plants don't have the stability they need to grow. This would be true for oceans too... but I'm less familiar with the area and the plants involved. Salt water has a tendency to be less forgiving to plants.
