Provision of ecosystem services is necessary for our quality of life. In this vein, itis critical to develop a baseline to monitor the ecosystem behavior usingmonitoring, mapping, and modeling indicators of landscape condition. Therepresentative watersheds (RWs) can therefore be considered as such decisionblueprint to implement the best management practices to conserve andconsequently improve ecosystem services. There are few researches for theselection of RWs. However, the comprehensive and of course applicablemethodologies still are lacked particularly in developing countries whereconcentration and proper directing of conservation measures are further neededowing to investments constraints. Therefore, in the present study, an intensivewatershed selection process was undertaken to identify RW across the Gharesoo-Gorgan River Basin (ca. 12987 km2), Golestan Province, Iran. This study aimed toadopt the Laize’s approach in Gharesoo-Gorgan Watershed for identifying therepresentative sub-watershed. Towards this, four GIS-based layers of elevation,slope, rainfall erosivity and land use were selected for sub-watershedscharacterization. The representative watershed index (RWI) was then calculatedand mapped using MATLAB 2016 and ArcGIS 10.3 softwares, respectively. TheRWI was calculated pixel wise for all nine individual sub-watersheds and the entirewatershed as reference area with the help of matrix combinations of four studylayers. Ultimately, RWIs obtained from 21.3 to 62.6 with mean of 44.94±14.49 andcoefficient of variation of 32.25% were used for sub-watershed prioritization.Accordingly, the sub-watershed 8 in north east with RWI of 56.8 was proposed asthe final RW for the whole Gharesoo-Gorgan Watershed. The results of the study ishelpful to be used by authorities for launching monitoring systems in the RW tocollect behavioral indicators leading to designation of reasonable ecoenvironmentalrestoration strategies.

Abstract Rapid Bioassessment Protocols (RBPs) were evaluated for use in monitoring the effectiveness of silvicultural Best Management Practices (BMPs) on 27 harvested sites in South Carolina. RBP bioassessments were compared to BMP compliance checks for agreement. The results indicate that a weight-of-the-evidence approach utilizing a BMP compliance check, a stream habitat assessment, and a benthic macroinvertebrate bioassessment is the most accurate method of evaluating BMP effectiveness. These data show that implementation of BMPs during harvesting operations was sufficient for the protection of the water quality of associated streams. South. J. Appl. For. 19(4):170-176.

Frequent Use

A survey of Georgia homeowners provided insights about their use of fertilizers and pesticides. Knowledge of current homeowner practices is needed to develop a best management practices manual to be used by Master Gardeners to train the general public through the existing outreach programs. The objective of the training program is to reduce nutrient runoff and garden chemicals and improve the quality of surface water in urban water-sheds. Results showed three of four homeowners did their own landscaping and, therefore, fully controlled the amount of applied chemicals and the area of application. Fertilizers were primarily applied to lawns, but a high percentage of homeowners also applied them to trees, shrubs, and flowers. Insecticides were applied by a larger percentage of homeowners than herbicides. Control of fire ants (Solenopsis invicta) was likely the reason behind the frequent use of insecticides. The desire for a weed free lawn was the plausible motivation behind the use of herbicides, which were used mostly on lawns. Fungicide use was infrequently reported by Georgia homeowners. The pattern of fertilizer and pesticide use suggests that the developed manual should emphasize techniques and cultural practices, which could lower the dependence on chemicals, while ultimately assuring the desired appearance of turf and ornamental plants.

Abstract Harvest access systems (forest roads, skid trails, and landings) account for 90% of the erosion and sedimentation during harvesting activities. A well-planned harvest access system can reduce the surface area disturbed by logging, thereby decreasing the potential for erosion and sedimentation. Most Best Management Practices (BMP) guidelines suggest that the area disturbed by the harvest access system should range from 10 to 15%. We measured surface area disturbance by the harvest access system on 43 harvest sites on nonindustrial private forestlands in northern hardwood cover types in New York State and found that the average area percent disturbed was 6% with a range of 3 to 13%. The quality of BMP implementation was positively associated with the percentage of surface area disturbed, suggesting that harvests with a low percentage of surface area disturbance do not necessarily exhibit high-quality BMP.North.

Improving the quality and consistency of the fresh mangos that are available to consumers in the United States is an important goal of the National Mango Board (NMB). The NMB-funded project, Monitoring and Evaluation of the Mango Supply Chain to Improve Mango Quality (referred to hereafter as the Mango Quality Project), was conducted from December 2007 through April 2009 to identify impediments to successfully meeting that goal. The final deliverable of the Mango Quality Project is this best management practices manual for harvesting and handling mangos marketed in the US. The manual includes quality-control procedures to use when monitoring the maturity and quality of mangos in commercial handling operations.
