Index of Subjects Fred makes a good suggestion on monitoring surface flow around cuts. I would be curious as to the method and tools we could use for this long-term monitoring. "Hobo loggers" placed in tiny tubes/wells in wetlands monitor water level okay, and loggers placed in streams can be useful, but I am not sure how one would quantify changes in surface run off from forests vs clearcuts. Someone must have figured this out somewhere along the way, but I have not come across it. Perhaps someone knows exactly how this set up with proper instruments could be carried out cheaply and easily (always the key factors for long-term monitoring to be successful). ? Donna Crossland.
