Survey no              : 27                              Area: 32.01 ha (Proper Forest)
30                                         35.05 ha           (Minor Forest)
31                                        2.07 ha    (Minor Forst)
51                                       74.79 ha (Minor Forest)                        
Protection required          : CPT for 8 km length
Village Forest Committee: No
Description of forest:  The forest is of degraded moist deciduous type, denser due to abundance of regeneration, weeds and bamboo. Large trees are sparse and many are in mutilated state. Basal area does not exceed 15 sq.m/ha. anywhere, whereas it needs to be more than  doubled to regain healthier composition.
Vegetation is characterized  deciduous tree species like Acacia auriculifois, Adina cordifolia, Alseodaphne semecarpifolia, Anogeissus latifolia, Bridelia retusa, Butea monosperma, Careya arborea, Chickrasia tabularis,  Dalbergia latifolia, Ficus religiosa, Ficus spp., Grewia tilifolia, Kydia calycina, Mallotus phillippnsis, Madhuca latifolia, Randia dumetorum, Stereospermum personatum, Syzygium cumini, Tectona grandis (reduced to stumps and coppice growth), Terminalia paniculata, Terminalia tomentosa, Xylia xylocarpa,  etc. Bambusa arundinacea is frequent and the forest is densely infested with weeds, prominently Eupatorium. Among the shrubs and climbers were noticed Abrus precatorius,  Acacia sinuata, Allophyllus serratus, Colebrookea oppositifolia,  Carissa carandas, Ichnocarpus frutescenc, Mucuna pruriens, Smilax macrophylla, Zizyphus rugosa etc.
Threats: Timber and fuelwood extraction, encroachments

Future management suggested

  1. Requirement of cattle-proof trench (CPT): CPT required for 8 km is recommended (see figure). CPT will be the immediate solution for preventing further encroachments
  2. 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.
  3. Species recommended for planting/natural regeneration: To be chosen from the indicative list
  4. VFC  formation: Constitution of VFC is very critical.
  5. Awareness programmes: To be conducted periodically in the village
  6. Meeting fuelwood crisis: 45 ha out of the almost 145 ha to be used for fuelwood species. Native species, as indicated in Table 1 are  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
