Burrowing organisms will recolonize as fast as necessary to prevent
suffocation. If sediment load is high, the burrowers will burrow fast..
Defining recolonization as opposed to escape burrows is subjective, and
would be somewhat defined by the nature (but not necessarily by the amount)
of burrowing. In other words, I do not view the argument as compelling in
the sense that you intend it to be. A continuous sediment load would
require continuous burrowing by the infauna.
