Ecological Restoration of Red Sanders (Pterocarpus santalinus L.) Forests – An Adaptive Collaborative Modelling Supported ApproachBackgroundRed Sanders (Pterocarpus santalinus L.) is an endemic and endangered tree species in souther India that is highly valued for its timber uses. Both anthropogenic and abiotic factors have led to the fragmentation and degradation of the Red sanders habitat. This project, which took place in Eastern Ghats: Kadapa, Southern Andhra Pradesh in July 2011, seeks to understand Red Sanders forest and explore the possibility for restoration.

Monitoring Forest Degradation in Tropical Regions by Remote Sensing: Some Methodological IssuesBackgroundThis review examines different remote sensing techniques to monitor vegetation cover at a regional scale. The objective was to discuss implications related to monitoring of open forest degradation. Research Goals & MethodsTechniques include methods to track both spatial and temporal changes in structure and function associated with land use change. Open access copy available |

Monitoring Mangrove Forest Dynamics of the Sundarbans in Bangladesh and India using Multi-Temporal Satellite Data from 1973 to 2000BackgroundIn the Sundurbans of India and Bangladesh, the authors measured the extent and condition of the mangrove forest at three intervals using GeoCover datasets (Landsat MSS, TM, ETM+) with the goal of assessing the current extent of the remaining forest, measuring change in the extent of the forest in different time periods, and identifying areas of intensive deforestation or degradation and changes in patterns of canopy density.

Simulating Forest Cover Changes of Bannerghatta National Park Based on a CA-Markov Model: A Remote Sensing ApproachBackgroundEstablishment of protected areas has been a primary response to deforestation and land-use change in tropical forests. However, few empirical evaluations have conducted a comparison of pre- and post-intervention landscapes. Open access copy available |
Deforestation and Reforestation of Latin America and the Caribbean (2001–2010)backgroundThis study examines contrasting forest cover change dynamics in Latin America and the Caribbean using MODIS satellite imagery. Many studies have documented deforestation, while others report forest recovery. This study seeks to analyze these trends on a large scale and connect them to environmental and population variables.

Landscape Pattern Dynamics and Mechanisms during Vegetation Restoration: A Multiscale, Hierarchical Patch Dynamics ApproachBackgroundThis study examines patterns of restoration using permanent plots and remote sensing of a nature reserve from 1979 to the present using a multiscale, hierarchical patch dynamic framework. Research Goals & MethodsThis study attempts to document changes in time and space during the restoration of forests with the purpose of understanding its patterns and processes.

Mangrove Ecosystem Recovery and Restoration from Oil Spill in the Niger Delta: The GIS PerspectiveBackgroundIn Nigeria, Mangrove's provide critical environmental and economic services, including maintaining water quality, serving as breeding grounds for important fish and crustacean, and as a source of food and materials. Yet, the country also has a history of oil spills that threaten these important ecosystems. In order to understand the effects of oil spills on mangroves, this study examines the land cover change of mangrove ecosystems in the Niger Delta between 1986 and 2008. Open access copy available |
