Abstract

This research presents the first detailed national wilderness mapping project conducted in Sri Lanka, aiming to identify and assess the spatial distribution of wilderness areas in the country. The study utilises a GIS-based Wilderness Quality Index (WQI), incorporating three main wilderness attributes: remoteness from public roads, absence of modern human interventions, and naturalness of land cover. The resulting wilderness quality map reveals several areas of high wilderness quality distributed throughout the country, with exceptions in the highly populated western region, where roads and built structures have significant impact. The research highlights the spatial correlation between the distribution of wilderness areas and protected areas, indicating that nearly all wilderness areas in Sri Lanka fall within the boundaries of existing protected areas. However, core wilderness areas outside existing protected areas, termed de facto wilderness areas, constitute a significant portion (19.7%) of total wilderness, raising concerns about their conservation status. The study emphasises the need for further evaluation to assess the ecological and landscape value of these areas and suggests new protected area boundaries. The wilderness quality map developed here provides policymakers with a valuable tool for future conservation planning, enabling informed decision making to preserve and protect Sri Lanka’s diverse and unique wilderness areas.
