Survey no                  : 289                                    Area: 9.33 ha  (Minor Forest)
290                                               4.98 ha  (Minor Forest)

Protection required          : CPT for 3 km length
Village Forest Committee: No
Description  of forest: The forest was formerly a kan forest, a village sacred forest of pre-colonial times. Kans were evergreen forests in earlier times. May be because of local communities losing their traditional control over the kan and conversion of the same into Minor Forest for meeting biomass requirements reduced it into a moist deciduous forest. Acacia plantation has also been raised in part of it. Of the evergreen trees what remain today are few: Carallia brachiata, Syzygium cumini, Hydnocarpus wightiana, Caryota urens etc. are few relics of the kan nature.
The notable trees in the forest were Adina cordifolia, Alangium salvifolium, Albizzia lebbeck, Buchanania lanzan, Careya arborea, Carallia brachiata, Cordia wallichi, Dalbergia latifolia, Diospyros melanoxylon, D. montana, Ficus benghalensis, Ficus callosa, Ficus drupacea, Ficus spp.,  Lagerstromia microcarpa, Lannea coromandelica, Madhuca latifolia, Mitragyna parviflora, Odina wodier, Olea dioica, Pterocarpus marsupium, Schleischera oleosa, Semecarpus anacardium, Spondias acuminata, Syzygium cumini, Terminalia bellirica, T. paniculata T. tomentosa, Xylia xylocarpa,  etc. Bambusa arundinacea is frequent in the forest; weed infestation is high in the openings.  Among the shrubs and climbers noticed were Calycopteris floribunda, Carissa carandas, Hemidesmus indicus, Holarrhena antidysenterica, Ichnocarpus frutescens, Jasminim malabaricum,   Zizyphus rugosa etc.
Threats: Extraction pressures and encroachments
Future management suggested

  1. Requirement of cattle-proof trench (CPT): CPT for 3 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. Forest has good potential for regeneration under protection of natural growth.
  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: Of the 14 ha forest, 7 ha may be used for fuelwood species. 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.
  7. Kan protection committee: Bringing awareness on the importance of kan protection it is recommended to constitute a committee of villagers for the same purpose.
