The Giant African Land Snail (GALS), considered one of the world’s most invasive species, has been spotted in various parts of Goa, India. The species, known for its large size and voracious appetite, is believed to have entered the state through transport routes from neighboring states such as Kerala and Karnataka, where it has already caused significant damage to crops and ecosystems. The first reported sighting of the snail in Goa was in 2015, and since then, there have been sporadic reports of its presence in different areas, including near Goa University, Margao, and Panaji.
Recently, there has been an increase in sightings, with multiple specimens spotted in areas such as Bogmalo, Varca, and Chicalim. The snails are hermaphrodites, meaning they have both male and female reproductive organs, which allows them to breed rapidly and colonize new areas quickly. Experts warn that if left unchecked, the GALS could become a significant threat to Goa’s native species and ecosystems.
The Goa State Biodiversity Board (GSBB) has expressed concern over the growing presence of the snails and has called for a state-wide surveillance to monitor their spread. Citizens are being encouraged to report any sightings, which will help in tracking the snails’ movement and taking preventive measures. Experts suggest using salt or tobacco decoction copper sulphate solution to destroy small populations of snails, but caution against using chemicals, which can harm the environment and enter the food chain.
The GSBB plans to include the GALS as a concern in Goa’s state biodiversity strategy and action plan, and is working with the agriculture department to develop a plan to control the snails’ spread. The board has also emphasized the need for close coordination between government agencies and citizens to prevent a catastrophic infestation of the snails.
The introduction of the GALS to Goa’s ecosystem could have severe consequences, including damage to crops, loss of biodiversity, and disruption of native ecosystems. It is essential to take immediate action to prevent the snails’ spread and protect Goa’s unique and fragile environment. With the help of citizens and government agencies, it is possible to prevent the GALS from becoming a major invasive species in the state.
