HEBBATI-RANGAPUR FOREST; ANDAGI PANCHAYAT
Survey no : 126 Area: 38.33 ha (Proper Forest)
6 B1 3.90 ha (Betta)
6 B2 1.33 ha (Betta)
221 A 4.05 ha (Betta)
222 B1 2.95 ha (Betta)
222 B2 1.53 ha (Betta)
223 1.39 ha (Betta)
224 B2 4.10 ha (Betta)
225 13.10 ha (Betta)
Protection required : CPT for 6 km length (as indicated in Figure)
Village Forest Committee: No
Description of forest: The forest, distributed in various survey nos. is in fragmented state. Encroachment, mostly by landless poor, has happened in a big way. Amidst the cultivated encroached area are large isolated trees, especially Terminalia bellirica, Terminalia tomentosa, Salmalia malabarica, Lagerstroemia microcarpa etc. Such remaining large trees in the middle of fields, on bunds, are slowly being eliminated through girdling and burning of base. Immediate task to form a VFC, number those trees and ensure their protection. Probably the forest was earlier of semi-evergreen kind, which due to human impact in the form of tree felling, fire incidence etc. turned into moist deciduous type.
Vegetation is characterized deciduous tree species like Bombax ceiba, Bridelia retusa, Butea monosperma, Buchanania lanzan, Careya arborea, Dalbergia latifolia, Dillenia pentgyna, Ficus benghalensis, , Ficus spp., Grewia tilifolia, Lagerstromia microcarpa, Madhuca latifolia, Syzygium cumini, Tectona grandis (mostly reduced to stumps and coppice growth), Terminalia bellirica, T. paniculata T. tomentosa, Xylia xylocarpa, etc. Bambusa arundinacea is frequent and the forest is densely infested with weeds, prominently Eupatorium due to large openings . Among the shrubs and climbers were noticed Abrus precatorius, Acacia sinuata, Allophyllus serratus, Calycopteris floribunda, Canthium parviflorum, Carissa carandas, Ichnocarpus frutescens, Zizyphus rugosa etc.
Threats: Continued degradation by human impacts and encroachments.
Future management suggested
- Requirement of cattle-proof trench (CPT): CPT for 6 km is recommended (see figure). CPT will be the immediate solution for preventing further encroachments
- Minimum basal area to be targeted: Under proper protection and management the basal area of trees could easily be increased to the least 35 sq.m/ha through replanting, natural regeneration and proper protection. Forest has good potential for regeneration under protection of natural growth.
- Species recommended for planting/natural regeneration: To be chosen from the indicative list
- VFC formation: Constitution of VFC is very critical.
- Awareness programmes: To be conducted periodically in the village
- Meeting fuel wood crisis: 45 ha out of the almost 145 ha to be used for fuelwood species. Native species, as indicated in Table 1. to be preferred for planting purpose. The remaining to be earmarked as conservation area and no biomass/NTFP to be harvested till forest recovery. Fast growing species and wood gasifier recommended. Households with adequate number of cattle should be assisted to install gobargas plants in. Astra stoves and solar devices (particularly for hot water) recommended to save use of fuelwood from forest.
- NTFP rights: To be given to the VFCs to be formed
