“…European settlement and military activities within the last 100-200 years further affected the modern environment. Comparisons of the Native American managed forest to satellite imagery during the 20 th century indicates that the land cover at Fort Benning has changed significantly (Olsen et al, 2007). The prevailing trend is a decrease in pine and increase in deciduous forest (Fig.…”

“…Pine forest cover decreased from nearly 80% to below 40% from 1827 to 1999. The increase in deciduous forest is mostly associated with riparian areas, as the riparian areas became Olsen et al, 2007). Data were collected from historic documents and satellite imagery.…”

“…Based on comparisons of forest composition inside the base to that outside the base, this plan has increased the habitat for endangered species, such as the RedCockaded Woodpecker (Picoides borealis), to a level that is higher than the regions outside of the military boundary (Olsen et al, 2007). Long-term data have also revealed the localized effects of management policies and are being used to design better policies that are sensitive to the range of biological diversity at Fort Benning.…”

Abstract:Analysis of land cover changes is fundamental for providing information about watershed land management, monitoring, and planning. This study reveals large-scale land cover transformation under the effects of frequent natural disturbances within the Taimali watershed in eastern Taiwan during [2005][2006][2007][2008][2009][2010][2011]. A landscape analysis approach combining landscape metrics and a Markov chain model is used to understand land cover changes with regard to natural disturbances. Results of the composition metrics analysis show that the landslide area within the region has expanded 7.5 times (15.5 km 2 ), but the forested area has shrunk by 10.6% (20.9 km 2 ). Spatial configuration metrics analysis indicates that patches of forest are becoming small, irregular, and spatially fragmented, while landslide patches are expanding and becoming spatially aggregated. Land cover changes in the area are considered to have occurred mainly through loss and fragmentation of forest cover, and an increase in the number and area of landslides. During 2005-2011, the most noticeable area changes related to transitions from forest cover to landslides (15.8 km 2 ) and channels (6.7 km 2 ). However, the greatest transition probabilities were for human-made patches changing into forest cover and channel corridors over the study period. Through the Markov chain analysis, three projected proportions of land cover for the periods 2017-2035 are produced. These three predictive scenarios pose different risks to downstream life and property.

Evaluating urbanization, fragmentation and land use/land cover change pattern in Istanbul city, Turkey from 1971 TO 2002

Spatiotemporal analysis of landscape dynamics is crucial in formulating an appropriate set of actions in landscape management. This paper presents a large scale analysis of the spatiotemporal structure of Istanbul, a highly urbanized city in Turkey, from 1971 to 2002 using forest cover type maps analysed with geographical information systems (GIS) and a spatial statistics programme. The quantitative evidence indicated that increasing population and expanding urbanization caused drastic changes to the temporal and spatial dynamics of land use/land cover pattern in Istanbul. There was a net increase of 5387Á3 ha in total forested areas (1Á0 per cent) due to mainly reforestation activities even though the population increased three times over a 31-year period. Increase in number of patches and decrease in mean patch size together demonstrated that the landscape developed into a more fragmented structure that would negatively affect biodiversity and the resilience of the ecosystems. In conclusion, plain increase in forest areas may not always be a favourable situation. The quality, composition and the configuration of forest landscape should also be analysed to present the dynamics of ecosystem in terms of ecological and economical sustainability over a longer time and larger area.
