Description Kerala State is the land of Black pepper, producing 97% of India's total output. There are about 16 species of pepper in Kerala, and it is essential to understand their genetic diversity. Surveys were conducted in various locations in Kerala and Piper species were collected. These were mapped using DIVA-GIS software for spatial analysis of plant genetic resource data, and the collected data were subjected to analysis for Piper species richness. Species richness is clearly not homogenously distributed within Districts. Piper nigrum and some of the related species originate in Kerala. DOMAIN and Bioclim models of DIVA-GIS were applied to map potential distribution sites of Piper species occurrence in Kerala. Based on the distribution and species richness, the areas where Piper species might be found have been predicted. DIVA-GIS was also used to predict the possible distribution of Piper species in other parts of India. Based on these prediction distribution maps, it is expected that most areas of north-east India, coastal Andhra Pradesh, Orissa and West Bengal are also likely to have many Piper species, while the chances of distribution of Piper species in other parts of the country are riote. The ideal annual rainfall distribution for these Piper species ranges between 2200 and 2700 mm and the frequency of the Piper species studied is very high in this range, though Piper species also occur in areas with 1500 to 3500 mm/yr. The distribution of Piper species at different altitudes was also studied and mapped using DIVA-GIS. Interestingly, all the species occur in the Silent Valley National Park in the Western Ghats, confirming earlier reports.The mapping exercise highlighted the joint effects of climate and soil on the distribution of wild Piper spp. The present study is the first report on the geographical distribution of Piper species using GIS.
