Invasive species
Not met yet — counts as met once you answer a question on it.
Non-native organisms — including Lantana camara, water hyacinth, and Suckermouth catfish — spread under conditions of habitat loss, agricultural expansion, and climate change, suppressing native biodiversity, disrupting food webs, and degrading ecosystem services. Competitive exclusion and niche displacement give invasive species disproportionate ecological advantage as native habitats shrink. The framework spans the Biological Diversity Act 2002, CBD's Kunming-Montreal targets, and India's National Biodiversity Action Plan. Controlling invasive species is essential to reversing biodiversity loss across terrestrial and aquatic ecosystems.
