India’s first Intertidal Bioblitz has concluded, recording a variety of intertidal species. The event was a collaborative effort between the Coastal Conservation Foundation and the East Coast Conservation Team, aiming to document the biodiversity of India’s intertidal zones. Notably, the bioblitz identified a flatworm species, Pseudoceros bifascia, for the first time along the Andhra Pradesh coast.
About the Intertidal Zone: The intertidal zone is a dynamic area where the ocean meets the land, characterized by its constant changes as it is submerged during high tide and exposed during low tide. It is a harsh ecosystem, where species must adapt to varying moisture, temperature, and salinity levels while also enduring strong waves.
Importance of Intertidal Zones:
- Breeding Grounds: They serve as crucial nurseries for marine life, offering protected environments for juvenile fish, crustaceans, and other species.
- Natural Buffer: They help mitigate coastal erosion by absorbing wave energy and stabilizing shorelines.
- Primary Production & Nutrient Flow: Intertidal zones are a vital source of primary production and play a key role in transferring energy, nutrients, and pollutants between terrestrial and marine environments.
- Carbon Sequestration: They are an important source of carbon capture.
Threats to Intertidal Zones:
- Climate Change: Rising seas, intensified storms, and temperature changes lead to species die-offs, disrupting the food chain.
- Human Impact: Activities such as oil spills, beach tourism, harvesting, pollution from various sources, and coastal development pose significant risks to these ecosystems.
