Urban wildlife often adapts to anthropogenic resources with unintended ecological consequences. Examine with examples.

Urban wildlife adaptation refers to species altering their diet, behaviour and habitat use to exploit human-generated resources — garbage, pet waste, stray animals and artificial light. Such behavioural plasticity aids short-term survival, but frequently creates ecological traps whose costs surface only later.

How urban wildlife shifts to anthropogenic resources

• Waste as predictable forage: Asian elephants in Uttarakhand's Haridwar–Lansdowne landscape feed at garbage dumps, with anthropogenic waste detected in roughly a third of dung samples surveyed [3].
• Prey substitution: leopards in Mumbai's Sanjay Gandhi National Park sustain an exceptionally high density (about 26 per 100 sq km), with domestic dogs the single largest contributor to their diet [2].
• Decomposers tracking new resources: the urban dung beetle Onthophagus orpheus now prefers dog faeces to cow dung, as omnivore waste dominates city landscapes [1].

The unintended consequences

• Preference–performance mismatch: though larvae on dog dung develop faster and grow larger, nearly 60% of brood balls fail against about 25% on cow dung — silently eroding a guild that drives nutrient cycling and secondary seed dispersal [1].
• Toxic ingestion: plastic forms the bulk of refuse recovered from elephant dung near dumps, causing digestive obstruction and mortality in an endangered species [3].
• Conflict and dependence: dog-subsidised predators are drawn deeper into settlements, raising human–wildlife conflict risk, even as they incidentally suppress rabies-carrying stray populations [2].

Governance implications

• Waste management is now an ecological, not merely sanitary, variable: siting norms keep landfills away from critical habitats and eco-fragile areas, and the Solid Waste Management Rules, 2026 tighten segregation and processing obligations on urban local bodies [4].
• Complementary measures — pet-waste disposal norms, animal-birth-control programmes and wildlife-proof bins — address the resource at source.

Adaptability in city wildlife is therefore a signal of ecological stress, not resilience. Treating urban waste as an ecosystem input, and integrating biodiversity concerns into municipal planning, would align urban governance with SDG 11 (sustainable cities) and SDG 15 (life on land), and with Article 48A's mandate to safeguard forests and wildlife.
