If the furrow is deep enough, and the plants are torn up and the roots are exposed and the sediment covers it, it can take decade or more to recover.

This is a struggling ecosystem. The last thing that a cash-strapped and short-staffed park needs is personal watercraft.

There are only about 4,000 marine-plant species compared with an estimated 250,000 species of terrestrial green plants. Similarly, of the 1.7 million-or-so known animal species, only about one-tenth are from oceans, with most of these living on or close to the bottom in relatively shallow water.

The plants are in a weakened state. Moisture is the key. We need rain.

You should start with what plants you like and see what conditions they require, and think about whether your yard can provide them.
