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 …

Effects of Forested Streamside Management Zone Widths and Thinning on Carbon Dynamics and Benthic Macroinvertebrates for Pine Plantations in the Piedmont of Virginia
… 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 thinning in 15.3 m SMZs were studied. The objectives of the study were to determine the effects these SMZ treatments …

Watershed and Streamside Management Zone Characterization in the Allegheny Plateau of West Virginia
The Streamside Management Zone (SMZ) is a cornerstone of forestry Best Management Practices to protect streamwater quality from non-point source pollution resulting from silvicultural operations. However, the exact width and harvest intensity of SMZs that best protects water quality while allowing …

Degradation and transport of veterinary antibiotics and estrogens in a vegetated buffer strip system
… and transport of the VAs sulfamethazine (SMZ) and lincomycin (LIN) and the estrogenic hormones estrone (E1) and 17[beta]-estradiol (E2[beta]) is important for assessing and mitigating the movement of these VAs and estrogens to surface or groundwater resources. Vegetative buffer strips …

Effects of Forestry Streamside Management Zones on Stream Water Quality, Channel Geometry, Soil Erosion, and Timber Management in the Virginia Piedmont
… 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 well as comparing other SMZ …

Streamside Management Zone effectiveness for protecting water quality following forestland application of biosolids
… 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 maintaining the other side …

A geochemical and stable isotope study of some rocks from the Bandelierkop formation, southern marginal zone of the Limpopo Belt, South Africa( vol.1 Text)
… Formation of the Southern Marginal Zone (SMZ) of the Limpopo Belt consists of metamorphosed ultramafic, mafic and sedimentary rocks. Metamorphic conditions indicated by the petrography of these different rock groups are consistent with upper amphibolite to granulite facies. The ultramafic …

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 …

Amphibian Population and Community Characteristics, Habitat Relationships, and First-Year Responses to Clearcutting in a Central Appalachian Industrial Forest
… plots that were in a Stream Management Zone (SMZ), and plots that were in upland, or non-SMZ, habitat. Distance to perennial or ephemeral streams or perennial ponds (SMZ classification), the amount of available rocks along transects, and site index were the 3 most important habitat variables …

The structural evolution of an ancient accretionary prism in the Damara Belt, Namibia
The Southern Marginal Zone (SMZ) of the Damara Belt, exposed in the Gaub Canyon in central Namibia, consists of fourteen lithotectonic units of high strain amphiholite facies rock with pelagic, hemi-pelagic and clastic sedimentary protoliths. These rocks are intercalated With lenses of metabasite. …

Application of phosphate and surfactant-modified zeolite for remediation/attenuation of trace elements in soil and coal fly ash
… ash leachate with surfactant-modified zeolite (SMZ) decreased the mobility of several trace elements. In general, up to 30% of the As, Mo, and V; up to 80% of the Cr; and up to 20% of the Se and Sr were removed from the leachate after SMZ treatment. Batch experiments, surface complexation …

A geochemical study of neoproterozoic palaeo-evaporites and their possible role in metallogenesis in the Damara Belt of Namibia
… Formation in the Southern Marginal Zone (SMZ) of the Damara Belt was carried out. The lithological units that make up the evaporite sequence within the Duruchaus Formation were mapped and sampled, along with discordant quartz-dolomite plugs intruding at various levels in the Duruchaus …

Amphibian and Reptile Community Responses to Forest and Riparian Disturbance
… Management Zones (i.e., riparian buffers; SMZs) are commonly implemented within managed forests to protect water quality, but may also provide habitat for riparian-associated wildlife. Yet, little research has rigorously addressed the value of SMZs for wildlife, particularly cryptic species …
