Description:
One of the requirements of the Canadian Standards Association (CSA) forest certification programme is that the licensee must maintain water quality within the Defined Forest Area (DFA). The programme requires that the licensee develop an objective measure to document how well water quality is being protected. It is also required that a target be set relative to the measure so that performance can be evaluated. To comply with these conditions in TFL 48, Canadian Forest Products Ltd. (Canfor) has developed an indicator for the protection of water quality that focuses on the evaluation of erosion and sediment delivery at steam crossings. This indicator has been termed the Stream Crossing Quality Index (SCQI). The SCQI field evaluation systematically assesses 1) the size and characteristics of sediment sources in the vicinity of stream crossings and 2) the potential for that sediment to reach the stream. If there is no potential for erosion, or the sediment cannot reach the stream, the crossing receives a score of zero (i.e. no hazard). As the number and size of the sediment sources with potential to be delivered to an individual stream crossing increase, so does that crossings score. A low score indicates good erosion and sediment control, while a high score indicates that there is a significant hazard to water quality caused by an accelerated introduction of fine sediments to the aquatic environment. The numerical score is used in two ways: 1) it is related to a categorical “hazard level” or “water quality concern rating” of none, low, moderate, high or very high and 2) the scores can be added up over an watershed and the sum of those scores can be used as an indicator of the potential for cumulative effects at the watershed level that would result from accelerated surface erosion.
