Description In the present study an attempt has been made to investigate the ?Effect of
Forest Fire on Microbial biomass, Storage and Sequestration of Carbon in a Tropical
Deciduous Forest of Chhattisgarh? at Bhoramdeo Wildlife Sanctuary of Kawardha
Forest Division in Kabirdham district during the year 2011?2013. The study was
conducted in four fire regimes viz., High, Medium, Low and No fire zones of tropical
deciduous forest. The variation in species structure, composition, diversity, biomass,
C storage, litterfall, net primary productivity, C sequestration, C stock, soil
characteristics and soil microbial biomass in all the fire regimes were quantified.
The observations of the study in the different fire regimes at surrounding areas
of Bhoramdeo Wildlife Sanctuary indicated that the agriculture is at subsistence level
and tribal people?s dependency on these forest resources for the livelihood in all the
respective sites. In all the fire regimes human settlement was mostly dependent more
or less on similar types of resources. In these sites, fires are ignited intentionally from
February to April to facilitate the collection of Tendu leaves and Mahua flowers and
also for honey collection. The chief source of energy and one of the resources used in
the entire site is fuelwood collection from the forest areas throughout the year. The
animal grazing is another heavy pressure in the study areas. Collection of non-timber
forest products (NTFPs) including leaf collection for making the plates (Dona),
medicinal plants and other minor forest produce by the human population is the
regular process in the area. These are the very important resource types recognized for
their high economic value to the people.
The present dry deciduous forest is characterized by poor species content. Non
linear inverse relationship between density vs. girth showed small structure with only
1.58- 2.18% individuals occurring in girth class >50 cm. In the present forests a total
of 380 trees ha-1 were encountered in high fire zone, 490 trees ha-1 in the medium fire
zone, 610 trees ha-1 in low fire zone and 880 tree ha-1 in the no fire zone. The basal
area of the tree species across the fire zone ranged from 11.13-33.54 m2 ha-1 lowest in
high fire zone and highest under no fire zone, respectively. Among the fire regimes
the no fire zone exhibited highest proportion of saplings and trees density, and
seedlings after the low fire zone.
The total biomass varied from 116.03 to 358.36 t ha-1 for tree, 6.82 to 15.71 t
ha-1 for shrubs 0.37 to 0.88 t ha-1 for herb, 6.58 to19.16 t ha-1 for fine root and 2.00 to
3.65 t ha-1 for litter mass. The above ground biomass was 111.99- 323.37 t ha-1 and
below ground was 23.68-65.17 t ha-1. The total carbon storage across the forest fire
