Description Sacred groves are unique landscapes and relies of original vegetation being preserved
under community conservation concept. The assessment of population status of RET species
was carried out in the sacred groves of Kodagu district. The growing stocks and regeneration
status of RET species with respect to their potential spatial distribution that are influenced by
ecological factors was assessed in ten sacred groves under semi-evergreen and seven groves
under moist-deciduous vegetation.
Species diversity of trees (H =2.570) and regeneration (H =3.673) and richness of
both trees (17) and regeneration (8.00) were higher in sacred groves of semi-evergreen than
that of moist deciduous vegetation. With respect to spatial pattern of RET trees Cannarium
strictum showed clumped pattern ( 2 = 8.7042) where as other species showed neither
clumped nor random pattern. In spatial distribution pattern of regeneration only Artocarpus
hirsutus showed clumped pattern (x2= 6.6716).
Assessment of species abundance was also done from data of both vegetation types.
Cinommomum macrocarpum acquired first position (398) with relative abundance (0.3376)
in case of growing stock and also in regeneration with recorded number of 245 individuals
and relative abundance of 0.4890. while considering individual vegetation type,
Cinommomum macrocarpum had 723 and 275 individuals in sacred groves of semi-evergreen
and moist deciduous vegetation respectively. From the pooled data of regeneration of both
vegetation types, the abundance with individuals of 188 and 157 and with relative frequency
of 0.5000 and 0.4830.
Regarding assessment of influence of ecological factors on population of RET
species, the ecological parameters such as latitude, longitude and rainfall had significant
influence on girth, height and basal area (r = 0.630, 0.49 and 0.597) respectively. The present
study confirms the hypothesis that mild disturbance had great influence on higher density of
RET medicinal species.
