Adyar Eco Park Phase-I: Also known as Tholkappia Poonga, the Adyar Eco Park has been set up in the Adyar estuary area. Opened in 2011, it is mostly covered by water and artefacts and signages. Out of 358 acres of land, the first phase of the Park covered around 58 acres, of which 4.16 acres are now in the CRZ-III zone. One-fourth of the 58-acre Park has been dedicated towards a conservation zone, which cannot be accessed by the public. In Phase-I of the ecological restoration plan, more than 91,280 saplings of 172 endemic species of trees, shrubs, herbs, reeds and tuberous plants, were planted, to create a habitat for aquatic, terrestrial and arboreal species.
