Recently, many forest companies, especially those located on the BC coast, have become interested in the possible danger that the runoff from log accumulations (log yards) may pose to the local flora and fauna and, ultimately, to humans. This info note attempts to put together practical information about how harmful runoff from log yards is created, how it can be prevented and give a brief overview of mitigation options. In creating this info note, a literature review was completed and a list of useful documents can be found near the end.
