Prior to field measurements (during the identification field experience), practice cover estimates were recorded randomly on the site to ensure consistency.
Percentage of canopy density was measured using a convex spherical forest densiometer, instrument design to estimate forest overstory density. This densiometer uses a convex spherical shaped mirror that reflects a large overhead area with a cross shaped grid containing 24 quarter-inch squares. Four imaginary equi-spaced dots have to be situated in each square. Then proceed to count those that represent an opening in the canopy (Figure 5). The complement of this number is multiplied by 1.04 and the resulting value corresponds to the percentage of overstory density (Lemmon, 1956). Four measurements were taken at each sample point (North, South, East and West) and the average was considered to be that point’s percentage of canopy density value. Sixty five points were recorded and measured in the Grady Tract

    Ecological sustainability is preservation of resilience of biophysics and system capacity to respond to the changes (Hanna and Munasinghe, 1995a, as cited in Pagdee, 2003, p. 10). Ecological sustainability can be assessed though forest status improvement in term of forest area increase, species diversity status, increase in forest products and values of species (Varughese and Ostrom, 2001 as cited in Padgee, 2003, p.11). Environmental problems resolve refer to erosion of soil and degradation of land (Klooster and Masear, 2000, as cited in Pagdee, 2003, p.11). Therefore, these improvements show the forest cover is maintained the system in future (Pagdee, 2003). 5.2 Social pillar Social sustainability of a community refers to capacity of the…

    They also determined that red oak, sugar maple, american elm, and burr oak had high importance values on low slopes and stream terraces (Adams 1980). These results were similar to what was discovered in the Ponca State Park study. Based on the Ponca State park study it was determined that Elm’s predominantly grow in the forest valley near a water source and the Burr oaks’s grow on the ridge top which was different between these two studies. This discrepancy could be due to the level of human interaction between the two locations at Ponca as…

    C factor is a ratio comparing the soil loss from land under a specific crop and management system to the corresponding loss from continuously fallow and tilled land. Although the USLE was developed for use on agricultural fields, the appropriate C factor are used for nonagricultural conditions. For this study, C factor values were taken from the USLE project results (Türkseven ve Ayday, 2000) carried out at the basin for agricultural areas and based on literature data published in Canga (1995) for forest, pasture and shrub. C factors for agricultural areas (wheat-fallow system), forest, shrub, pasture and water surface were considered 0.15, 0.001, 0.20, 0.01 and 0.0, respectively. Support Practice Factor (P) It reflects the effects of practices that will reduce the amount and rate of the water runoff and thus reduce the amount of erosion.…

Then we started our research with Forest LFA, including landscape organization assessment (LOA) and soil surface assessment (SSA). Firstly, we set up a 50m transect running directly up and down the slope and mapped patches and interpatches on this transect. We regarded the place where resources could be accumulated as patches, like grass, shrubs, logs or trees.…

    There were three types of quadrat methods such as list quadrat, list-count quadrat and chart quadrat. Out of these three methods we applied list-count quadrat method for phytosociological study. In every study site, we randomly studied 20 quadrats of 100 m × 100 m size for tree species, 30 quadrats of 5 m × 5 m size for shrub species and 50 quadrats of 1 m × 1 m size for herb species. 4.2.1 Quantitative analysis The important quantitative analysis such as density, frequency and abundance of tree, shrub and herb species were determined as per Curtis and McIntosh (1950). Frequency (%) Terms of percentage occurrence indicates the degree of dispersion of individual species in an area.…

    Zimmerer discussed types of property in association with a nature society hybrids. The article discussed the four geographical themes that were interested in debates over conservations. These themes included conservation, degradation, conservation and scale, conservation territories, conservation boundaries and environmental linkages. The object of the authors essay was to link the conversation of geographies into a conversation of nonequilibrium ecological science (Zimmerer, 2000). More specific to nature society hybrids, Zimmerer discussed the effectiveness of a nature society hybrid.…
