When water springs out of the earth and trickles into a rocky mountain stream it is clear, cold, and clean. One stream merges with another and the water flows out of the mountains, through the foothills, under bridges, past towns and cities, fields, forests and pastures. As it travels toward the sea it turns a little muddier, warmer, more polluted. This is a natural process. The water in the Saluda River, as it flows into Lake Greenwood, may not be as clear as it was when it started as a mountain stream, but the more forests the water flows through on its long descent the cleaner it will be, because forests act as natural filtration systems. This is why the quality of the entire watershed is so critical to the quality of the water you drink.
Forester Dale Mayson travels from Greenwood to Pickens to Lexington to Spartanburg making sure that the rivers and streams from the foothills to the mountains keep that critical forest buffer.
Point vs. Non-Point
Forestry practices account for a relatively small percentage of the pollution affecting our waterways, but South Carolina is a heavily forested state and the wood products industry is our third largest manufacturing industry. On large tracts of forestland where timber is being harvested, nonpoint source runoff due to poor logging practices can be a threat to water quality.
Guidelines for Forestry
There are enforceable regulations in the Clean Water Act that relate to nonpoint source polluters, but, for the most part, BMPs are voluntary in South Carolina, and, as it turns out, that is a good thing.
Dale Mayson is the Forestry Commission's BMP forester in the Piedmont Region. He regularly checks harvesting and site preparation operations for compliance with BMPs and has found, to his satisfaction, that the percentage of forestry operations that comply with the guidelines is very high. Part of the reason for this is the cooperation among the state's major forest industries, the SC Forestry Association, the Forestry Commission, loggers, forestry consultants and contractors.
Charles Doolittle is a logging contractor working out of Newberry who has been recognized by the SC Forestry Association as a Logger of the Year "We always use Best Management Practices. In fact we try to go beyond what's recommended" says Doolittle, "The BMP manual outlines simple precautions a logger can take prior to a harvest operation. It's simply not worth it to take shortcuts and risk affecting soil or water quality."
Which BMPs Apply to Your Land?
For example, the term ‘streamside management zone’ refers to a buffer of undisturbed ground cover on either side of a stream, river, pond… any body of water. The recommended width of a streamside management zone (SMZ) will vary depending on the slope of the bank adjacent to the body of water. That slope is likely to be steeper the more hilly the terrain. In flat country, recommended buffers might be only forty feet wide. But here in rolling country or in mountainous terrain, where the slope might be greater than 40%, the guidelines could recommend 160 feet or more. The width of recommended SMZs around sensitive trout streams in the mountains could be over 200 feet. The reason for the difference, of course, is that as slope increases so does the potential for runoff and erosion. The wider the SMZ, the more effective the natural filtration. Trout require cool, clear streams. They and the aquatic insects they feed on are sensitive to both increased sedimentation and increased water temperature. The broad SMZ around a trout stream guards against runoff and provides cooling shade.
In coastal wetlands and bottomland hardwood areas, flat, wet conditions sometimes contribute to the formation of shallow, braided streams, so-called because of their multiple, interconnected channels that resemble the strands of a braid. These streams have broad valleys and defined floodplains. A characteristically high water table results in soil with rich organic content. The process of determining the recommended width of a streamside management zone around a braided stream can be quite complex. There are supplemental BMP guidelines that address protection of braided streams.
Dennis Bauknight inherited forestland in the mountains near Dacusville from his father. He learned basic principles of good forest management as a boy. "We sometimes harvest timber in rugged areas. We pay particular attention to BMPs for stream crossings, road and skid trail construction. In country like this it is especially important to leave wide forest buffers on either side of a stream. I follow BMP guidelines and rely on Dale Mayson's expertise."
Forest Roads
There are many more BMP guidelines for timber harvesting, site preparation and reforestation, plus recommendations for common forestry practices like prescribed burning, application of pesticides and fertilizer, improvement of wildlife habitat including protection of endangered species, and drainage and ditching activities.
Protect Your Land and Water
Ask for a Courtesy BMP Exam
Mayson also flies over the state's major drainages each month to locate active logging and site preparation operations. Once sites are identified, he contacts the landowner for permission to conduct a courtesy exam. It is not too late for recommendations to be made and followed even after logging has begun. If damage has already occurred, Mayson will suggest ways to mitigate the damage. A Forestry Commission statistical survey shows that compliance with BMPs is 99% on sites where a Courtesy BMP Exam has been conducted.
At the end of each month, results of the exams from all over the state are summarized in a report that lists the operators who failed to implement BMPs, with the failure resulting in a water quality impact. This report is sent to the SC Department of Health and Environmental Control and to the state's forest industries. If a water quality impact resulted from a forestry operation, DHEC may initiate enforcement action under the South Carolina Pollution Control Act. Individual forest products companies, through the Sustainable Forestry Initiative SM, may use this information to take corrective action as they deem necessary. For most loggers, this is a real incentive to stay off the list. But the majority of South Carolina's loggers don't need to worry. They are professional operators who have an investment in preserving the quality of our environment.
Working Together Works
The forestry community in South Carolina can be justifiably proud of our environmental record. The Forestry Commission's proactive strategy to prevent non-point source pollution due to forestry practices has proven very effective. Compliance with BMPs has risen from 84.5% in 1989 to 91.5% in 1999 and 99% on tracts where a Courtesy BMP Exam was conducted. The National Oceanic and Atmospheric Administration (NOAA) has promoted our program for use as a model, and similar approaches have been adopted by other states. In the fall of 2000, South Carolina's BMP program and its director, Darryl Jones, received a national environmental protection award from the EPA.
Forestry is a very important business in South Carolina. About 65% of our total land area is forested. And private landowners own 72% of that forestland. Timber harvesting on private land drives the market in this state, so it is private landowners that ultimately bear the responsibility for the health of our forests and the quality of our soil and water. Fortunately there are good forest protection guidelines and a network of assistance in place.
