Landscape characterisation of the forests of Himalayan foothills
2010
Deforestation and degradation are important aspects of landscape dynamics and have global significance. Quantification of landscape pattern using landscape metrics help in characterisation of landscapes and thus overall health of the forest cover. Himalayan foothills are one of the most important and fragile landscapes. Developmental activities and depdendence on the forest resources have altered the spatial pattern of these natural landscapes to a great extent. These changes in the landscape were analysed using satellite data from 1990, 2001 and 2006. The vegetation type maps of Dehradun forest division were prepared by supervised classification technique in order to study the landscape dynamics. Patch density, edge density, shape index, cohesion index, interspersion and juxtaposition index, normalised entropy, and relative richness are some important landscape metrics used in the study for quantifying the characteristics of landscape. The landscape metrics analysis and transformation analysis show that the forested areas are getting degraded and physical connectedness between the patches have also decreased making them isolated. The study demonstrates the importance of geospatial tools for monitoring the impact of disturbances on the forest ecosystem health, which can further help in landscape management.

Improving image classification and its techniques have been of interest while handling satellite data especially in hilly regions with evergreen forests particularly with indistinct ecotones. In the present study an attempt has been made to classify evergreen forests/vegetation in Moulitig National Park of Arunachal Pradesh in Eastern Himalayas using conventional unsupervised classification algorithms in conjunction with DEM. The study area represents climax vegetation and can be broadly classified into tropical, subtropical, temperate and sub-alpine forests. Vegetation pattern in the study area is influenced strongly by altitude, slope, aspect and other climatic factors. The forests are mature, undisturbed and intermixed with close canopy. Rugged terrain and elevation also affect the reflectance. Because of these discrimination among the various forest/vegetation types is restrained on satellite data. Therefore, satellite data in optical region have limitations in pattern recognition due to similarity in spectral response caused by several factors. Since vegetation is controlled by elevation among other factors, digital elevation model (DEM) was integrated with the LISS III multiband data. The overall accuracy improved from 40.81 to 83.67%. Maximum-forested area (252.80 km 2) in national park is covered by sub-tropical evergreen forest followed by temperate broad-leaved forest (147.09 km2). This is probably first attempt where detailed survey of remote and inhospitable areas of Semang subwatershed, in and around western part of Mouling Peak and adjacent areas above Bomdo-Egum and Ramsingh from eastern and southern side have been accessed for detailed ground truth collection for vegetation mapping (on 1:50,000 scale) and characterization. The occurrence of temperate conifer forests and Rhododendron Scrub in this region is reported here for the first time. The approach of DEM integrated with satellite data can be useful for vegetation and land cover mapping in rugged terrains like in Himalayas.
Vegetation Analysis in Kumaun Himalaya using Remote Sensing
Vegetation and land use of Kumaun Himalaya was analyzed using remote sensing data. A total of 15 vegetation and land use classes were mapped, of which, eight vegetation types and seven land use categories were identified. Utilizing the knowledge of altitude bound distribution of vegetation digital elevation model (DEM) was used for the postclassification refinements. Forest spreads over 52% of total geographical area, while 48% of the total geographical area is covered with non-forest types including scrub, grassland, plantation, agriculture, water body and snow. Temperate and subalpine broadleaf forest dominated the forest class followed by pine forest. Information generated in present study will provide input to planners for land use planning and natural resources management.

Among the specific difficulties encountered while mapping vegetation and landuse utilizing remote sensing data (LANDSAT LS.S.)jn mountainous areas like the Himalaya of Central Nepal, one has to deal with the different lighting conditions of the slopes at the moment of data collection. The original ASS data have not been corrected; they have been clustered and treated separately according to sun illumination, An Illumination model elaborated from a topographical map has been worked out and utilized to identify 3 types of homogeneously lightedsiopes.
seamless vegetation type map of India (scale 1: 50,000) prepared using medium-resolution IRS LISS-IIIimages is presented. The map was created using an on-screen visual interpretation technique and has anaccuracy of 90%, as assessed using 15,565 ground control points. India has hitherto been using potentialvegetation/forest type map prepared by Champion and Seth in 1968. We characterized and mappedfurther the vegetation type distribution in the country in terms of occurrence and distribution, areaoccupancy, percentage of protected area (PA) covered by each vegetation type, range of elevation, meanannual temperature and precipitation over the past 100 years. A remote sensing-amenable hierarchicalclassification scheme that accommodates natural and semi-natural systems was conceptualized, and thenatural vegetation was classified into forests, scrub/shrub lands and grasslands on the basis of extent ofvegetation cover. We discuss the distribution and potential utility of the vegetation type map in a broadrange of ecological, climatic and conservation applications from global, national and local perspectives.We used 15,565 ground control points to assess the accuracy of products available globally (i.e., GlobCover,Holdridge’s life zone map and potential natural vegetation (PNV) maps). Hence we recommend that themap prepared herein be used widely. This vegetation type map is the most comprehensive one developedfor India so far. It was prepared using 23.5 m seasonal satellite remote sensing data, field samples andinformation relating to the biogeography, climate and soil. The digital map is now available through aweb portal
Vegetation mapping is a primary requirement for various management and planning activities at the regional and global level. It has assumed greater importance in view of the shrinkage and degradation in forest cover. Usage of remotely sensed data for mapping provides a cost -effective method. In the pre- sent study vegetation cover assessment has been done using remotely sensed data in West Siang District of Arunachal Pradesh. Standard method was adopted for ground data collection by establishin g the correla- tion between satellite data and various vegetation types. Ground data were collected extensively and sufficient information was obtained. Vegetation class i- fication was performed using traditional methods of image recognition. The discrimination among the various forest types is restrained on satellite data o w- ing to the environmental set-up, intermixing of sp e- cies/vegetation and topography. However, to achieve higher accuracy, other methods have been considered. Hybrid...
