A caller tidal mangrove nursery has been established astatine Killai adjacent Pichavaram successful Cuddalore district. The archetypal of its benignant successful the State, the nursery holds astir 3 lakh saplings, and is designed for the hardening of mangrove seedlings successful earthy tidal conditions.
Unlike accepted nurseries, wherever adjacent the usage of saltwater cannot afloat replicate the coastal environment, this set-up makes usage of earthy tidal movement. Seedlings are placed connected floating platforms and kept successful tidal waters for six to 8 months.
During this period, they acclimatise themselves to salinity, h2o movement, and tidal fluctuations. As a result, the seedlings acquisition a carnal translation from soft, tender maturation to a hardier signifier with thicker stems. This makes them much resilient and amended suited for endurance successful coastal environments, and leads to a higher post-transplant endurance rate.
“The endurance complaint is much than 90%,” said B. Iqbal, Forest Range Officer, who developed the method nether the method guidance of A. Gopu, Assistant Conservator of Forests, Green Tamil Nadu Mission.
District Forest Officer S. Gurusamy said 4 taxon are being raised successful the nursery — Avicennia marina, Avicennia officinalis, Rhizophora mucronata, and Rhizophora apiculata. While each mangrove taxon could perchance payment from the method, these 4 were selected for their size. Smaller taxon are much susceptible to submersion during precocious tides.
Pichavaram is location to 13 existent mangrove species, and the caller nursery is expected to enactment semipermanent restoration crossed the portion nether the Green Tamil Nadu Mission and the World Bank-funded Tamil Nadu Coastal Restoration Mission (TN-SHORE).
One of the main advantages of this approach, noted Supriya Sahu, Additional Chief Secretary, Departments of Environment, Climate Change and Forests, is that it facilitates year-round propagation, removing the constraints of abbreviated effect postulation windows and ensuring a dependable proviso of planting material.
