The roots even hold onto those sediments which leads to better water quality and a reduction in erosion. While most terrestrial plants use whats called a taproot to burrow deep into the ground for support, several mangrove species rely on sprawling cable roots that stay within a few centimeters of the soils surface for stability and access to oxygen. << Since leaf cells can hold a large volume of water when compared to all other cells, salt is drawn to the leaves as a mechanism to balance the salt concentration. endobj /Rotate 0 << To differentiate species that use different methods for dealing with salt, scientists categorize mangroves as either secretorsthose that actively rid their tissue of saltand non-secretorsthose that block the salt from entering their tissue. /Macrosheet /Part >> /C [0 0 1] In 2006, two nearby archipelagos were washed away, an illustration that the threat of the entire forest vanishing beneath the ocean is a real concern. /F5 52 0 R They grow mangrove seedlings in greenhouses and then transplant them into mudflats along the oceans edge. /CropBox [0 0 612 792] /Parent 3 0 R /S /URI 15 0 obj Litterfall production, decomposition and nutrient accumulation in /S /Transparency >> /Tabs /S Areas of the Sundarban mangrove forest have experienced unusually high tides and as a result high levels of erosion.
