Seaweed on a gravel yard

Seaweed on a gravel yard

Asked on 9 Sep, 2008

I live in Wiltshire on the side of a slight hill - we have water running off the fields after it rains [ heavy clay] which then flows away across a gravel yard.

After a wet period sea weed like vegetable matter appear on the surface of the gravel - there are no apparent roots or attachment.

During the dry summer days [ remember them] these plants shrivel and die away.

Does anyone know what type of plant it is and how to curb it ??
