Biodiversity loss is increasing globally due to many anthropogenic factors including invasive species. Among the invasive species, the giant African land snail which is World’s worst invasive species is threatening the native species and become major pest for economy loss. Although the impact of snail is widespread in Nepal, we have little knowledge on their distribution and spreading factors. Using species distribution modeling, we found more than 50% of their potential area at Tarai region followed by Siwalik (29%) and 20% in mid-hill regions. The findings indicated that the species has potential for spreading to the high-mountain areas due to road and transportation. Inspite of past history of the species occurrences, the current distribution expanded across the entire country in the low lands and mountain regions. Therefore, we recommend government to prevent the potential spreading of the giant African land snail in Nepal by developing and devising policy measures to control the species in and around the roadsides. In addition, we suggest the government for proper cleaning of vehicles and transporting materials before transportation or area specific quarantine through public awareness.

由于包括入侵物种在内的许多人为因素，全球生物多样性丧失正在增加。在入侵物种中，非洲巨型蜗牛是世界上入侵最严重的物种，正威胁着本地物种，并成为造成经济损失的主要害虫。尽管蜗牛的影响在尼泊尔很普遍，但是我们对蜗牛的分布和传播因素知之甚少。使用物种分布模型，我们在塔莱地区发现了超过50％的潜在面积，其次是西瓦里克（29％）和中山地区的20％。研究结果表明，由于道路和运输，该物种具有传播到高山地区的潜力。尽管有该物种发生的历史记录，但目前的分布范围遍及全国低地和山区。因此，我们建议政府通过制定和制定政策措施来控制路边及其周围的物种，以防止非洲巨型蜗牛在尼泊尔的潜在扩散。此外，我们建议政府通过公众意识在运输或特定地区隔离之前适当清洁车辆和运输材料。
