# India State of Forest Report 2023 (Volume 1) ## Executive Summary Periodic assessment of forest resources of the country based on robust scientific methodologies is a pre-requisite for monitoring of these resources and better planning for the forestry sector. Forest Survey of India, an organization under the Ministry of Environment, Forest and Climate Change, has been mandated to carry out a regular assessment of forest resources of the country using satellite data and field based information and publish the results in a biennial report named as India state of Forest Report (ISFR). The first report was published by FSI in 1987 and since then 17 such reports have been published by FSI. The ISFR 2023 is 18th in the series. The information on various forestry parameters given in the ISFR are very useful for monitoring of the resources, evaluation of the various polices and making better planning for optimum utilization of the forest resources. In addition, the inputs given in the report are very useful for monitoring of NDC targets, reporting of Green House Gas (GHG) inventory to UNFCCC for the forest land under the LULUCF sector, and country reporting to FAO for the Global Assessment of Forest Resources. The first major input that goes into the ISFR is forest cover mapping of the country based on nationwide forest cover mapping using satellite data. The forest cover is defined as “all lands, more than one hectare with a tree canopy density of more than or equal to 10% irrespective of ownership, legal status and land use. Such lands may not necessarily be a recorded forest area. It also includes orchards, bamboo and palm". In the current cycle, Forest Cover Mapping has been carried out using medium-resolution indigenous satellite data, with a spatial resolution of 23.5 m sourced from the Indian Space Research Organization's (ISRO) indigenous LISS-III sensor, part of the IRS Resourcesat satellite series, at a scale of 1: 50,000. This satellite data was acquired for all states within the timeframe of October 2021 to December 2021. In certain regions of the country, such as the North Eastern region, the coastal belt, and the Andaman and Nicobar Islands, additional satellite images were procured for the period from January 2022 to April 2022, to obtain better-quality satellite imagery. This specific time window was chosen because it typically offers cloud-free satellite data and full vegetation foliage, resulting in enhanced reflectance and precise satellite image interpretation. The classification of forest cover used in the present report is based on tree canopy density, viz., Very Dense Forest (VDF) having canopy density equal to or more than 70%, Moderately Dense Forest (MDF) having canopy density equal to or more than 40% but less than 70%, and Open Forest (OF) having canopy density equal to or more than 10% but less than 40%. The Forest Cover is assessed using an approach involving satellite digital image processing; visual image analysis; ground verification by the analysts and State Forest Departments; incorporation of post-field corrections; quality checks including ground validation by officers; followed by generation of output in the form of maps and area statistics. Over the years, this methodology has continuously evolved and improved to keep pace with advancing technology and the latest image interpretation techniques. Since the initial forest assessment report in 1987, the methodology for Forest Cover Mapping has been consistently refined and updated. To ensure consistency, uniformity, and a high level of accuracy in the Forest Cover Mapping exercise, all steps of the methodology have been standardized. To minimize subjectivity, a comprehensive manual has been developed to guide and facilitate these processes, helping to maintain the quality and reliability of the mapping results. The second major input that goes into ISFR is based on the inventory of Forests and Trees Outside Forests (TOF) under the National Forest Inventory (NFI) Programme of FSI. FSI launched a National Forest Inventory in 2002, with the onset of the 10th five-year plan, by developing a sampling design, to generate the national level estimates of growing stock and other parameters. Under this NFI design, the country was stratified into 14 physiographic zones and 60 districts were selected for the detailed inventory for a cycle of 2 years. About 3,500 sample plots were inventoried in the forest areas and 5000 sample plots were inventoried in TOF every year. FSI modified the sampling design of NFI in 2016, considering the data requirements at National and International level, to generate the precise estimates at the State level and to reduce the revisit time from 20 years to 5 years. Under the modified design, FSI has switched over to a grid based design having uniform grids of size 5 km x 5 km and selecting specified grids each year for the detailed inventory. Under this design, FSI is laying about 6,000 plots in forest area and 10,000 plots in TOF areas every year. The information of growing stock, tree cover, bamboo stock, carbon stock, agroforestry and important characteristics are derived from the field inventory data collected from forest and TOF. The ISFR 2023 has been produced into two volumes considering the wealth of information generated from forest cover mapping and NFI. The Volume-l gives the national level assessment such as forest cover, mangrove cover, forest fires, growing stock, carbon stock, agroforestry, important characteristics of forest and decadal change. The Volume-ll gives information about forest cover for each State/UT of the country, districts and divisions and state wise information derived from the field inventory. ## Salient Findings: * The total forest and tree cover of the country is 8,27,356.95 km<sup>2</sup> which is 25.17% of the geographical area of the country.

Some of the highlights are given as follows: * There is a general improvement in soil health (87.16% of shallow to deep soil as against 83.53% in 2013) reflected by improvement in humus (18.04% medium to deep humus as against 11.43% in 2013) which is, in turn, reflected in better grass cover (17.21% dense to very dense grass cover as against 15.64% in 2013) and better undergrowth (25.58% dense to very dense undergrowth as against 20.32% in 2013). * The soil organic carbon has also increased marginally during this period from 55.85 tonnes per hectare to 56.08 tonnes per hectare. * The load of moderate to heavy grazing has come down to 35.79% as compared to 41.04% in 2013. * Biotic influences on forests have also come down to 26.66% from 31.28% in 2013. All this has reflected in increase in forest areas under mixed size classes (38.11% as against 21.12% in 2013), which indicates improved floral biodiversity, and improved surroundings for faunal biodiversity. ## Table: Forest and Tree Cover of India | Class | Area (km<sup>2</sup>) | Percentage of GA | |---|---|---| | Forest Cover | 7,15,342.61 | 21.76 | | Tree Cover | 1,12,014.34 | 3.41 | | Total Forest and Tree Cover | 8,27,356.95 | 25.17 | | Scrub | 43,622.64 | 1.33 | | Non Forest | 24,16,489.29 | 73.50 | | Geographical Area of the country | 32,87,468.88 | 100.00 |
