Re: Not just a forestry problem, December 2 letter.
I totally accept Karl’s point that woody debris coming down the rivers is not all from forests; some of it naturally originates from riparian vegetation. But I can assign no blame nor offer any means of mitigating this aspect of the problem other than capturing the stuff before it reaches the bridges and the sea.
What I can say is that a huge volume of debris originates from the harvesting of over 2 million tonnes of saleable logs each year, and that material could and should be prevented from entering the waterways.
