Abstract: | India is one of the 12 mega biodiversity countries in the world. There are still many areas where inadequate information on
plant wealth is available. Gap area prioritization is of utmost concern to understand the species richness of different parts
of India. In this context survey-gap analysis was carried out to assess exploration status and to prioritise areas using integrated
approach through taxonomical data and geoinformatics. In order to highlight the gaps in botanical exploration in the country,
the present case study was conducted in Adilabad district of Andhra Pradesh. A grid size of 5′×5′ has been prepared to analyse
the exploration status. The results indicated that most parts of study area have been under-explored and unexplored. Of the
200 grids, only one grid has been well explored with species collections of above 100. The study brought to light that moist
deciduous forests were not covered during floristic studies. Comparative analysis with disturbance index and biological richness
maps evidently points out that explorations were undertaken only in high disturbed zones and areas of low to medium biological
richness. This geospatial analysis clearly points the need for more attention to the exploration of tropical forests in India.
There is a need of systematic botanical studies to prioritise the conservation strategies of varied natural ecosystems. It
is recommended for national level survey-gap analysis as an important step to determine the floristic wealth, species representativeness
and distribution. |
