Nutrient Movement in Streamside Management Zones and Piedmont Streams Following Forest Fertilization
Many states' Best Management Practices (BMP) programs established Streamside Management Zone (SMZ) widths based on limited or inadequate data with regard to nutrient fluxes from silvicultural activities. Previous studies in forested watersheds have shown slight post-harvest increases of several …

Effects of Forestry Streamside Management Zones on Stream Water Quality, Channel Geometry, Soil Erosion, and Timber Management in the Virginia Piedmont
… objectives include determining if a 50-foot streamside management zone (SMZ) as described in the Virginia BMP Manual (VDOF 2002) is generally sufficient to protect stream water quality, riparian soils, and stream bank integrity in headwater streams where forest harvesting has taken place, as …

Economic Tools to Improve Forest Practices' Outcomes
… In chapter three, a novel approach to design Streamside Management Zones widths that vary according to different landscape characteristics is presented, as opposed to the constant command and control width currently used in Virginia. This adaptive approach allows landowners to maximize land …

Loggers' perceptions of the costs of best management practices on timber harvesting operations in Virginia
… the estimated cost for implementing best management practices (BMPs) on harvested sites. BMPs analyzed in this study are pre-harvest planning, road construction, broad base dips, water turn-outs, water bars, streamside management zones, stream crossings, and site stabilization. Loggers …

Logging in the Streamside Management Zone: Effects of Harvesting System and Intensity on Visual Soil Disturbance
Streamside management zones (SMZs) are a common and effective mechanism used to protect and maintain water quality during timber harvesting operations. In the southeastern United States timber harvesting is typically allowed inside the SMZ, but there is little information regarding suitable types …

Effects of Forested Streamside Management Zone Widths and Thinning on Carbon Dynamics and Benthic Macroinvertebrates for Pine Plantations in the Piedmont of Virginia
… Act of 1972 promoted the establishment of Best Management Practices (BMPs) for forestry. A commonly used BMP is the reservation of Streamside Management Zones (SMZs). In this study the effectiveness of three different SMZ widths, 30.5 m (100 ft), 15.3 m (50 ft), and 7.6 m (25 ft), as well as …

Streamside Management Zone effectiveness for protecting water quality following forestland application of biosolids
… to increase nutrient availability. Retaining streamside management zones (SMZs) can limit nutrient pollution of streams. We delineated 15 m SMZs along three intermittent streams in an 18-year-old Pinus taeda L. plantation. We applied biosolids outside the SMZ on one side of each of the streams …

Amphibian and Reptile Community Responses to Forest and Riparian Disturbance
<p>Riparian zones are transitional, semi-terrestrial areas regularly influenced by freshwater. These areas serve as dispersal corridors for many animal and plant species and ultimately function as important reservoirs of biodiversity in altered landscapes. While much of the riparian habitat in the …

Operational characteristics, erosion potential, and implementation of forestry best management practices on biomass harvesting operations
… on soil erosion and implementation of Best Management Practices (BMPs) for water quality on biomass harvesting sites. Results indicate that biomass harvesting was integrated into a wide range of logging businesses. Existing biomass harvesting businesses reported total production levels …

Relationships Between Streamside Management Zone Width and Biotic Communities of Headwater Streams in West Virginia
The importance of streamside management zones (SMZ) in minimizing the impact of non-point source pollution from silvicultural operations is recognized by the forestry Best Management Practices of most states. However, research concerning the SMZ width and harvesting intensity required to maintain …

The Hillslope Hydrology of a Mountain Pasture: The Influence of Subsurface Flow on Nitrate and Ammonium Transport
… state governments have recommended the use of streamside management zones (SMZ) to reduce the amount of NPS pollutants. A small agricultural watershed in southwestern North Carolina was utilized to quantify subsurface transport of nitrate and ammonium to a naturally developing riparian area …

Effectiveness of State Developed and Implemented Forestry Best Management Practices in the United States
… operations. Properly applied forestry best management practices (BMPs) have since been proven to protect water quality from forest operations. This research project reviewed BMP effectiveness studies in the U.S., assessed current state developed and implemented of forestry BMPs, and …

Evaluating Energywood Harvesting Operations in The Lower Mid-Atlantic Region of the United States
… and adequacy of conventional water quality best management practices (BMPs), increased area in road network features due to increased machine trafficking, and reduced quantities of residual woody debris. Energywood harvesting operations have been established in the lower Mid-Atlantic region of …

Potential Effects of Forestry Best Management Practices and Implementation Rates on Soil and Water Resources in the Southeastern United States
Forestry Best Management Practices (BMPs) include guidelines, recommendations, and protocols utilized to protect forest water quality from nonpoint source pollutants (NPSP). Sediment is the most common NPSP associated with forest operations, and BMPs are implemented primarily to reduce erosion and …
