2. Regeneration Natural Regeneration Artificial Regeneration

3. Natural Regeneration Good regeneration when the conditions are suitable: Tidal influx and occurrence of river water flow Natural regeneration by Seed and Propagule

4. Changes in geomorphological and hydrological conditions , the natural regeneration of mangroves is hindered.

5. Artificial Regeneration Why nursery: Variation in season of seed maturity and season of plantation. Nursery raised seedling survival is 50-90 % more than that of direct dibbling. In field new emerging seedlings are damaged by crabs. Well established root system in nurseries.

6. The major requirements for a mangrove nursery site Areas with periodic inundation. Access to good quality salt and fresh water. Pumps for pumping saline water from the creeks for the saplings Access to road/creek to mobilize transport and labour to the planting sites. Good quality propagation stock.

7. Nursery Layout

8. Selection of species

9. Collection of seed material and planting in the nursery Majority of seeds mature in July and December Fallen seeds and propagules: Low tide and Floating by Hand nets Mature seeds from the standing trees: Rhizophora , Sonneratia . Transfer the collected propagules in the soil on the same day Seeds of this species has less viability and hence take fresh seed. Wildings: Excoecaria

10. Nursery Techniques Soil : Clayey Poly bags: 5 inch x 8 inch. Flooding provision for the beds. Horizontally place bamboo to keep the seedlings intact

11. Also sow germinated seeds in the poly bags. Di ammonium phosphate, urea and micronutrients may be sprayed to enhance growth. Pesticides may be sprayed after draining the water. Shift the poly bags regularly Nursery Techniques contd.
