Abstract Compliance with 60 forestry best management practices (BMPs) in Maine was evaluated from a sample of 120 sites randomly selected from areas harvested during the period January 1, 1993 to December 31, 1994. The forestry BMPs were organized into six groups [haul roads, stream crossings, skid roads/trails, putting trails/roads to bed, log yards/landings, and streamside management zones (SMZs)]. Applicability of each practice was assessed at each site and compliance with applicable BMPs rated. Evidence of sediment movement was used as a measure of BMP effectiveness. Compliance with the various BMPs within each of the six groups ranged as follows: haul roads 34%-100%; stream crossings 31%-94%; skid roads/trails 49%-95%; putting trails/roads to bed 25%-88%; log yards/landings 53%-96%; and SMZs 42%-78%. Low levels of compliance per se may overstate the negative impacts in those cases where BMPs are applicable on a small number of sites. For example, compliance with the recommendation that water courses be forded only on hard bottoms and banks was low (54%) but was applicable to only 39 sites, affecting 21 of the 120 sites examined. Overall compliance was greatest for the BMPs related to yards and landings (81%) and was lowest for putting trails/roads to bed (54%). Compliance levels in Maine were similar to those reported in Vermont and Minnesota. Compliance tended to be higher for those BMPs associated with planning and layout of haul roads and skid trails, compared to those dealing with water diversion from long, unobstructed surfaces. Old roads pose a challenge. Many road systems in use today were constructed a decade or more ago by scraping surface soil down to the basal till generating low road surfaces bounded by high banks. Ditches slowly eroded and became ineffective in diverting water from the road surface. Corrective measures are expensive, and new water diversion ditches will disturb more of the area. This study supports the utility and effectiveness of commonly recommended BMPs in reducing erosion and sedimentation in Maine. When BMPs were used, sediment movement was eliminated completely or was largely restricted from surface waters. Numbers of sites at which appreciable sediment delivery to surface waters was associated with noncompliance of individual BMPs within each of the six categories are summarized as follows: haul roads 1-17 sites; stream crossings 0-17 sites; skid roads/trails 0-20 sites; putting trails/roads to bed 9-14 sites; log yards/landings 1-14 sites; and SMZs 1-9 sites. In total, noncompliance with at least one BMP was associated with a downstream sediment trail at 34 sites. North. J. Appl. For. 15(2):57-68.

<p>Understanding the impacts of global climate change on the spatiotemporal pattern of hydrologic cycle and water resources is of major importance in highly developed watersheds all over the world. These impacts are strongly dependent on related changes in intensity and frequency of extreme climate events. Implementation of Best Management Practices (BMPs) and policy approaches at watershed and regional scales is essential for mitigating their negative impacts on soil and water conservation, and sustainable economic development. However, the uncertainty of BMP effectiveness including increasing variability of future water supply and changing magnitudes of nonpoint source pollution has to be accounted for in watershed planning and management. This paper provides a review and discussion on the impacts of global climate change on BMP’s hydrologic performance, the current progress on hydrologic assessment of BMPs, as well as the existing problems and countermeasures. Research challenges and opportunities in the field of hydrologic assessment of BMPs under global climate change are also discussed in this paper.</p>

Abstract Forty-two forestry best management practices (BMPs) were assessed to determine the extent of voluntary application and their effectiveness in preventing water quality impacts in New York State. These BMPs were evaluated on 61 timber-harvested sites in the Catskill region (CR), and 53 timber harvested sites in the Adirondack region (AR) during the summers of 1997 and 1998. The overall application of suggested BMPs was 78% for haul roads, 87% for landings, 59% for skid trails, 88% for equipment maintenance/operation, and 73% for buffer strips. Departures were common for BMPs concerned with draining water off haul roads and skid trails, and for stream crossings; more attention must be devoted to those practices. Effectiveness of BMPs was apparent when they were applied. Nonparametric statistical tests showed a strong relationship between BMP application and prevention of sediment movement. Limiting sediment movement protects surface water. In the CR, 27 of the 33 BMPs tested showed a statistically significant (P < 0.10) relationship between BMP application and sediment movement. Similar results were observed in the AR; 26 of the BMPs tested were significantly associated with sediment movement. Imperfect application of BMPs reduced effectiveness. Road drainage structures, for example, generally failed to adequately control erosion when spacing between drainage structures was excessive. North. J. Appl. For. 17(4): 125–134.

The Look

Everyone enjoys the look of a nice, healthy lawn in a landscape. Not only do lawns increase the value of property, they help to cool the environment and reduce soil erosion. Most importantly, a healthy lawn reduces pollution resulting from stormwater runoff, because it is able to actively filter and trap sediment or pollutants that might contaminate ground or surface waters. It is very important that homeowners follow best management practices when maintaining their lawns so as to not cause pollution to Florida's water resources. For a happy, healthy, and environmentally friendly lawn, follow the tips outlined in this document. This document is Fact Sheet ENH979, one of a series of the Environmental Horticulture department, Institute of Food and Agricultural Sciences, University of Florida.

Final Selection

Ground-based mechanized forest operations often lead to increased runoff and soil loss on unbound forest roads and machine operating trails, which in turn can impede the technical trafficability of machines and cause negative impacts on the environment. The aim of this study was to evaluate the effectiveness of three Best Management Practice (BMP) treatments used to control erosion occurring on machine operating trails. The treatments included water bar, water bar and hardwood brush (H-brush), and water bar and softwood brush (S-brush). For a more comprehensive assessment of both brush treatments, two levels of brush thickness were tested; 0.5 m and 1.0 m. Results indicate that the most effective BMP treatments were the water bar and softwood brush followed by the water bar and hardwood brush and finally the least effective was the water bar. The average runoff rates and soil loss from the machine operating trails with the water bar treatment (52.64 l per plot, 8.49 g m-2) were higher than runoff and soil loss at the trails protected with hardwood brush (23.75 l per plot, 4.5 g m-2), and the trails protected by the hardwood brush had higher runoff and soil loss compared to trails covered by softwood brush (15.83 l per plot, 2.98 g m-2). Furthermore, results of this study showed that regardless of the treatment, the amount of runoff and soil loss decreased consistently as the thickness of the brush mat increased. Overall, erosion control techniques similar to either H-brush or S-brush that provide direct soil coverage should be used for erosion control, and final selection should be based on costs, availability of material, or landowner objectives.

Best Management Practices for water quality (BMPs) have been proven effective in reducing sedimentation from timber harvesting operations. Although most states in the country have BMP guidelines, many are non-regulatory, creating challenges for forest managers to ensure implementation. In surface watershed systems, BMP cost-sharing extension programs (BMP programs) are designed to encourage the implementation of BMPs. To assess the efficacy of a BMP program we examined the rates of BMP implementation on 45 properties harvested between 2013 and 2015: 22 harvests enrolled in a BMP program and 23 harvests not enrolled. We also compared our results to two previous studies completed in 2002 and 2011. Our results indicate BMP implementation was significantly better on properties participating in the BMP program. Also, BMP implementation scores improved for almost all categories evaluated when compared to the two previous studies. One BMP category with low implementation scores (even in 2018), was water diversion devices such as water bars. We suspect the BMP program is not sufficient to incentivize implementation given the time commitment for BMP implementation. Another factor at play here is that implementation may have been perceived as adequate to manage surface flow, but not optimal according to specifications dictated by the BMP field guide.

Forest Operation

In-stream watershed level evaluations confirm that application of recommended forestry best management practices (BMPs) can minimize sedimentation following management, while on-site erosion research shows that BMPs reduce erosion from individual forest operations, thus implying watershed-level sediment reductions. Assessments of forest operations and sediment have developed very few sediment delivery ratios (SDR). Linking BMP levels (low, standard recommendation, high) within specific forest operations to sedimentation could enable managers to evaluate BMP effects. Reported data regarding forest operations, erosion rates and SDR by forest operation, and BMP implementation levels were sufficient within the Piedmont region to allow approximations of sediment delivery and BMP efficiency. Existing United States Department of Agriculture (USDA) Forest Service reports and published erosion and sediment research were used to comprise the following method. For regional annual harvests, estimated sediment deliveries (Mg year−1) = annual harvest area (ha year−1) × weighted average erosion rate from all forest operations (Mg ha−1 year−1) × SDR (unitless ratio). Weighted average erosion rates for all forest operations were determined by applying areas in each operational activity (%) × estimated erosion per operation (Mg ha−1 year−1). In comparing published data, standard BMPs reduced estimated sedimentation by 75% compared to low BMP implementation levels. This supports forestry BMP efficiency findings reported for sediment removals in watershed studies. Higher levels of BMP implementation were estimated to potentially remove nearly all forest operation-produced sediment. Values of this pilot study should be viewed cautiously, as estimates were based on limited data, estimated operations, and limited SDRs; are based on BMP categories that vary between states; and address only one year following harvests. However, the approach provided approximations that facilitate BMP evaluations and can be improved with additional data. This methodology highlights the importance of accurate estimates of erosion rates, SDRs, sediment masses, and area for operations. This supports the importance of state programs, which have increased BMP implementation rates and compliance options with BMP program maturation.

Negative Impacts

Neonicotinoids have been the most commonly used insecticides since the early 1990s. Despite their efficacy in improving crop protection and management, these agrochemicals have gained recent attention for their negative impacts on non-target species such as honeybees and aquatic invertebrates. In recent years, neonicotinoids have been detected in rivers and streams across the world. Determining and predicting the exposure potential of neonicotinoids in surface water requires a thorough understanding of their fate and transport mechanisms. Therefore, our objective was to provide a comprehensive review of neonicotinoids with a focus on their fate and transport mechanisms to and within surface waters and their occurrence in waterways throughout the world. A better understanding of fate and transport mechanisms will enable researchers to accurately predict occurrence and persistence of insecticides entering surface waters and potential exposure to non-target organisms in agricultural intensive regions. This review has direct implications on how neonicotinoids are monitored and degraded in aquatic ecosystems. Further, an improved understanding of the fate and transport of neonicotinoids aide natural resource practitioners in the development and implementation of effective best management practices to reduce the potential impact and exposure of neonicotinoids in waterways and aquatic ecosystems.
