CHIKKADUGLI FOREST; BASI PANCHAYAT
Survey no : 22 Area: 46.84 ha (Minor Forest)
30 38.36 ha (Proper Forest)
Protection required : CPT for 2.50 km length
Village Forest Committee: No
Description of forest: The forest is today of moist deciduous nature, whereas the rainfall of 1800 mm could have been good enough for semi-evergreen forest. The forest is subjected to desiccation due to canopy gaps, increased levels of human interference and probably sporadic fires. Today deciduous tree species dominate the vegetation.
Of the notable trees are Adina cordifolia, Alseodaphne semecarpifolia, Aporosa lindleyana, Buchanania lanzan, Butea monospema, Careya arborea, Cordia myxa, Dalbergia latifolia, Diospyros melanoxylon, Ficus spp., Helictres isora, Holarrhena pubescens, Lannea coromandelica, Mangifera indica, Phyllanthus emblica, Pterocarpus marsupium, Syzygium cumini, Tabernamontana heyneana, Terminalia bellirica, T. paniculata T. tomentosa, Xantolis 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, Embelia tsjeriam-cottam, Hemidesmus indicus, Ichnocarpus frutescens, Jasminim malabaricum, Smilax zeylanica, Zizyphus rugosa etc.
Threats: Extraction pressures and encroachments
Future management suggested
-
Requirement of cattle-proof trench (CPT): CPT for 2.5 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 fuelwood crisis: Of the 85 ha forest, about 25 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. All these steps are dissuade people from depending heavily on forests for routine biomass needs.
-
Village Forest Committee: VFC has to be constituted for better management of this fragmented and highly impacted forest.
