“…The increase in soil micro-aggregates (regulating service), consistent with patterns reported in other sites in Chamela (Cotler and Ortega-Larrocea, 2006), as well as in other semiarid grasslands (Zhou et al, 2010), suggests a decrease in soil fertility regulation along the duration gradient, which likely contributed to the observed decrease in forage quality. Soil organic matter associated with microaggregates is highly processed by microbial activity, is less physically protected and is diminished in its potential nutrient mineralization, when compared to that in macro-aggregates (Elliott, 1986).…”

“…On the other hand, Island Safari is a private property with an exclosure to protect it from any exploitation. Human induced disturbances determine the vegetation structure and composition of forests by their influences on the regeneration success of woody species (Cotler and Ortega-Larrocea 2006). The considerable floristic variations (species richness, genera, families and overall diversity) between the two open sites (Shorobe and Xobe), were probably due to their differences in the soil types and moisture availability (Chimbari et al, 2009;Neelo et al, 2013).…”

Stand structure, diversity and regeneration status of woody species were investigated in open and exclosed dry woodland sites in Island Safari, Shorobe and Xobe, northeastern Botswana. A total of 105, 111 and 130 quadrats, measuring 20 × 20 m each, were laid down along parallel line transects in the three sites, respectively, to collect data. A total of 47 species, representing 16 families and 24 genera, were recorded in the study sites. Of these, 33 species representing 13 families and 20 genera, 41 species representing 15 families and 23 genera and 27 species representing 10 families and 14 genera were encountered in Island Safari, Shorobe and Xobe, respectively. The most diverse family was Fabaceae followed by Combretaceae and Tiliaceae at all the three sites. The most diverse genus was Acacia, followed by Combretum and Grewia. The diversity of woody species in the study sites were 2.18, 2.15 and 1. sii and A. luederitzii in Xobe. The alarming result was the fact that 71%, 80% and 85% of the woody species recorded in Island Safari, Shorobe and Xobe, respectively, exhibited hampered regeneration and, thus, unhealthy population structures. Therefore, there is an urgent need to address the observed unhealthy population structures of the woody species through investigation of the major causes of their hampered regeneration, and also designing measures that will facilitate natural and artificial regeneration of these species at the three study sites.

“…There are many factors affecting runoff quality from forest areas including rainfall intensity, temperature, altitude, slope, topography, soil erosion, vegetation, forestry operation, forest canopy, forest BMPs and litterfall, among others (Grace 2005;Li et al 2005;Cotler and Ortega-Larrocea 2006;Stuart and Edwards 2006). The finding that undisturbed forested condition has the least sediment yield and has no apparent impact on the receiving water body (USEPA 2000b) may not be true in Taiwan, especially on those reservoirs that receive runoff from forest areas.…”

Water quality and unit nonpoint sources (NPS) pollution load from a forest area were studied in a mountainous watershed in Taiwan. The flow rates were measured with rectangular weirs and samples taken for water quality analysis in both non-rainy and rainy days for 2 years. The subroutine of the Hydrological Simulation Program--FORTRAN was used to simulate runoff for additional 3 years. Total annual loads of various water quality parameters were then estimated by a regression model. Most of the parameter concentrations are higher during the rainy days; their values are typically higher as compared to data from other undisturbed forest areas. Nevertheless, the concentration ratio of dissolved inorganic nitrogen to TN or PO4(3-) -P to TP shows TN or TP no correlations with the flow rates, whereas the concentrations of SS and TP are positively correlated with the flow rate. The fluctuation of annual load from this watershed is significant. For example, six major events of the entire year, for which the total duration is merely 6.4 days, contribute 42% of the annual precipitation and at least 40% of the annual NPS loads. The management for controlling the NPS pollution from this forest watershed is discussed.
