RE: effective environmentally friendly cleaners for beach areas?

poor little dog might get hot and tired working so hard all day...  what about some owl decoys (although I guess they would eventually habituate).  I think the H2O2 suggestion is a great one.

It seems to me that a well trained border collie would do a job like
this all day.

Cheers, Peter Boyer.

The idea of wires strung above the dock could be a simple and useful
approach to deter the gulls if it is as successful as observed in a
field test at a beach in California where the gulls avoided the beach
area underneath wires.

 I wonder if the gulls would be willing to just leave the dock if there
is not another dock to go to.

They might also want to explore some sort of gull deterrent in the
future such as placing wires above the dock.

Hi Shannon:

I am assuming that the dock surface is above the waterline. If so,
the likely safest thing to use on the Dock is dilute Hydrogen
Peroxide (3%). When exposed to organic matter and sunlight and
bacterial action it breaks down to water and oxygen. I would apply it
liberally to teh "messy dock surface", let it sit until the bubbles
stop and then hose it off.
