The roots even hold onto those sediments which leads to better water quality and a reduction in erosion. Some of these invasive species are encroaching upon the habitats of mangroves. Mangrove forests save lives. As the plants develop into trees, they become more tolerant of cold temperatures and are better able to withstand periodic freeze events during the winter. Through a series of impressive adaptationsincluding a filtration system that keeps out much of the salt and a complex root system that holds the mangrove upright in the shifting sediments where land and water meet. Scientists will refer to this as the mangal, but mangrove or mangrove forest works just the same.

Although for a time, fear of the creatures and the inaccessibility of their chosen habitat protected the tigers from human poaching, recent sea level rise is now threatening their existence. Part of a mangrove forests value comes from its ability to modify and support the surrounding environment. Not mangroves. Extensive mangrove diebacks in Australia along the Bay of Carpentaria in the Northern Territory and at Exmouth in Western Australia have been linked to a 14 inch (35 cm) drop in sea level, which when coupled with prolonged drought, left mangroves high and dry long enough to cause extensive mangrove death.

The stunted growth is often attributed to a lack of nutrients, high salinity, and rocky soils. They are also important because they provide a habitat for other species that live in the ecosystem, like fish and birds. The problem is that this approach doesnt work very well.
