  • The Union Minister for Environment, Forest and Climate Change, Shri Prakash Javadekar released the biennial “India State of Forest Report (ISFR)”, in New Delhi.
  • The report is published by the Forest Survey of India (FSI) which has been mandated to assess the forest and tree resources of the country including wall-to-wall forest cover mapping in a biennial cycle. Starting 1987, 16 assessment have been completed so far.
  • ISFR 2019 is the 16th report in the series. As compared to the assessment of 2017, there is an increase of 5,188 sq. km in the total forest and tree cover of the country.
  • “Out of this, the increase in the forest cover has been observed as 3,976 sq km and that in tree cover is 1,212 sq. km; Range increase in forest cover has been observed in open forest followed by very dense forest and moderately dense forest and the top three states showing increase in forest cover are Karnataka (1,025 sq. km) followed by Andhra Pradesh (990 sq km) and Kerala (823 sq km).”
  • In tune with the Government of India’s vision of Digital India, FSI’s assessment is largely based on digital data whether it is satellite data, vector boundaries of districts or data processing of field measurements.
  • The biennial assessment of forest cover of the country using mid-resolution Satellite data is based on interpretation of LISS-III data from Indian Remote Sensing satellite data (Resourcesat-II).
  • For the first time, Ortho-rectified satellite data has been used for forest cover mapping due to its better positional accuracy as it removes effects of image perspective (tilt) and relief (terrain) and scale distortions in the image to represent features in its true positions for accurate measurement of distances, angels and areas.
  • FSI, in a first ever attempt has carried out a rapid assessment of biodiversity for all the States and UTs (except two) and for all the sixteen Forest Type Groups as per Champion & Seth Classification (1968).
  • Apart from the number of tree, shrub and herb species as observed in the survey, Shanon Wienner Index which gives species richness along with the relative abundance, has also been calculated for each forest type groups in each State & UT.
