Study Notes
India State of Forest Report 2023 Executive Summary
- Periodic assessment of forest resources is crucial for monitoring and better planning in the forestry sector.
- The Forest Survey of India (FSI) is mandated to conduct regular assessments using satellite data and field information.
- The India State of Forest Report (ISFR) is a biennial report, with the 2023 report being the 18th in the series.
- ISFR data is useful for monitoring resources, evaluating policies, and optimizing forest utilization.
- Input from the report aids in monitoring NDC targets, reporting GHG inventory, and country reporting for Global Forest Resource Assessments.
Forest Cover Mapping
- Forest cover is defined as lands exceeding one hectare with a tree canopy density of 10% or more.
- This includes orchards, bamboo, and palm, regardless of ownership or legal status.
- Current mapping uses medium-resolution indigenous satellite data from the Indian Space Research Organisation (ISRO) LISS-III sensor.
- The spatial resolution is 23.5 m, collected between October 2021 and December 2021.
- Additional imagery from January 2022 to April 2022 was acquired in specific regions like the Northeast, coast, and islands for higher quality.
Forest Cover Classification
- Classification is based on tree canopy density:
- Very Dense Forest (VDF): Canopy density ≥ 70%
- Moderately Dense Forest (MDF): Canopy density ≥ 40% < 70%
- Open Forest (OF): Canopy density ≥ 10% < 40%
Forests and Trees Outside Forests (TOF) Inventory
- The National Forest Inventory (NFI) is used to assess growing stock and other parameters.
- The country was stratified into 14 physiographic zones.
- 60 districts were selected for detailed inventory assessments.
- 3,500 sample plots were inventoried in forest areas and 5000 plots inventoried in TOF annually.
- FSI modified the NFI sampling design in 2016 to improve State-level estimates and reduce revisit cycles to 5 years.
Salient Findings (2023)
- Total forest and tree cover is 8,273,569.95 km² (25.17% of the geographical area).
- The total forest cover is 7,153,426.61 km² (21.76%).
- Tree cover is 1,120,143.34 km² (3.41%).
- National-level forest cover increased by 156.41 km² compared to the previous assessment.
- Increases in forest cover observed in Chhattisgarh, Uttar Pradesh, Odisha, and Rajasthan.
- Decreases in forest cover observed in Madhya Pradesh, Karnataka, Ladakh, and Nagaland.
- State-specific details about the increase and decrease in forest cover and TOF information are provided.
Other Key Findings
- The extent of TOF (forest outside reserved forests or gazetted areas and tree cover) is 30.70 M ha (37.11% of total forest and tree cover).
- Maximum tree cover: Maharashtra, Rajasthan, and Uttar Pradesh.
- Analysis of forest cover changes in Western Ghats Eco-Sensitive Areas (WGESA) has been performed.
