Abstract
Changes in land-use patterns affect a landscape by changing the composition of local flora and fauna. The lateritic plateaus in Konkan are one such example of this rapid land-use change. Although these plateaus are rich in endemic flora and fauna, they are considered “wastelands” due to a lack of woody vegetation and thus, are subjected to various land uses. Mango cultivation in this region has become a major source of income due to its Alphonso variety of mangoes. Hence, over the last few decades, many plateaus have been converted into mango orchards. However, how the conversion of plateaus to mango orchards has affected the species composition of different groups of organisms remains unclear. In the present study, we sampled the lateritic plateaus and plateaus converted into mango orchards in Ratnagiri, Maharashtra, to investigate the response of the reptile communities. We observed more species heterogeneity in the orchards compared to the unaltered sites. Moreover, it appeared that there was a species turnover when the plateaus were converted into orchards. The generalist and widespread species such as agamids and skinks and very few specialist species were comparatively more abundant in the orchards. On the contrary, the plateaus without orchards harboured more specialist species such as Hemidactylus albofasciatus (n=62, in unaltered sites vs n = 5 in the orchards), Echis carinatus (n = 15 in unaltered sites and none in the orchards) and Ophisops jerdonii (n=45 in unaltered site vs n=12 in the orchards) compared to the generalist species.

2) per_cover
Species data
This CSV file contains the following raw data.
-
Site type - whether the site was an Orchard or an Unaltered site. This is a categorical variable with two variables - 'Orchards' and 'Unaltered site'
-
Site - The name of the site. The sites are named, 'Orchard 1', 'Orchard 2', 'Orchard 3', ' Unaltered site 1', ' Unaltered site 2', and' Unaltered site 3'.
-
Species_name - The species encountered in that site.
per_cover
This CSV file contains the following raw data.
-
Sites - Site where the plots were laid.
-
Plot - the number of plot.
-
Substratum - the type of substratum. This is a categorical variable with for type of substratum calculated for each plot, 'Bare ground', 'Grass', 'Shrubs and Herbs' and 'Leaf litter'.
-
Percentage - the percentage of that substratum calculated for that plot.
