This study compared the use of wood chips and slash to reduce the loss of sediment on newly constructed forest road slopes and investigated the annual amount of sediment loss on bare forest road slopes. A runoff block (sample field) was established for each of the four designated test sites (two cutslopes and two fillslopes). Each block had three runoff plots. One of the runoff plots was left empty for the control (CNT), while wood chips (C) and slash (S), respectively, were deposited in the other two. A total of 108 water samples were taken from the test sites and the amount of their suspended sediment calculated in the laboratory. As a result of this study, it was determined that the amount of soil loss in the control plots was about 1.26 times higher than in the slash plots and 2.21 times higher than in the wood chips plots. According to the results of variance analysis on the amounts of sediment, a statistically significant difference was found between the suspended sediment quantities transported on the road slopes (p < 0.05). However, no statistically significant difference between the suspended sediment quantities transported in the plots and the other variables of aspect, gradient or road slope was revealed by the t-test (p > 0.05).

“…Analytical hierarchy process (AHP) is a math-based GIS-compatible and multidisciplinary decision method utilized in various fields and also in the planning of routes, construction, and maintenance of roads and railways and subways [48][49][50][51][52]. At the same time, AHP is also preferred and used in forestry studies [53][54][55][56][57][58]. In the AHP method, analysis can be subjective inasmuch as the factors are limited through user-specified constraints [46].…”

Afforestation activity needs serious feasibility in as much as it is a work of establishing a new facility. Moreover, the process of selecting the land to be afforested; determining site conditions; selecting suitable tree species, provenance, and clones; the planting or sowing techniques; and planning of the environmental transport network are all costly. Determining suitable areas for environmental road network installation, which has an important place in afforestation areas, is discussed in this study. In this context, characteristics of an afforestated area have been evaluated by virtue of the fuzzy inference system (FIS) and modified analytical hierarchical analysis (M-AHP) methods on a sample area established as an afforestation area. The main objective of this study is planning in a way that is sensitive to nature and strives for ecological balance on environmental forest road networks for forested and afforested areas by utilizing multiple decision support methods with a view to realizing maintenance on afforestation areas in short-and long-term processes. A total of eight factors were determined in the study. The best twelve models, obtained as a result of analyses carried out with these factors, are presented. The success of the models was evaluated with receiver operating characteristic (ROC) analysis and the best model was obtained by M-AHP, which was Model 4 M-AHP with 71.2% area under curve (AUC) value. We observed that the model obtained through the M-AHP method is more successful in on-site road network planning during the phase of creating the afforestation projects.

“…As stated in this paper, the AHP method "is applied in many and different research fields, including nature, economy and society". Recent applications of the AHP method in forestry involve, among other issues, forest road assessment [39], evaluation of non-wood forest products [40], analysis of forest fire risk [41], and ranking of indicators of sustainability [42].…”

The forestry sector in Chile has an important role in the domestic economy, being the second leading export sector after the mining industry. Investments in forest plantations have grown in the last 40 years thanks to implementation of the Decree Law 701. Planted forests currently account for 17.4% of the total national forest cover. The objective of the study is to analyse non-industrial forest owners' perceptions of positive and negative externalities of forest plantations in four less developed municipalities of the Maule Region. We implemented a literature review, the estimation of an Expert's Response Indicator (ERI), and the implementation of an Analytic Hierarchy Process (AHP) methodology for the analysis. The results indicate that non-industrial forest owners in the four municipalities perceive the importance of each externality in a different way according to their territorial specificities. However, considering the whole study area, "CO 2 sequestration", "improvement of livelihood", and "more importance of small and medium forest owners" were considered the most important positive externalities, while the most relevant negative externalities were "water shortage", "power asymmetry", and "land loss". The study encourages further research with a similar detailed analysis on stakeholders' perceptions of plantation projects, both to revise investment features and inform local stakeholders on their real impacts.
