Further investigations are needed into the threat of deterioration of mangroves at several sites caused by camel browsing and hydrological changes. Dredging and filling activities for infrastructure purposes have caused flooding of mangrove habitat. Whilst in previous times, human activity has caused different types of problems for the mangrove ecosystem, the council and public nowadays have strived to implement strategies and regulations that need to be followed so that it benefits the environment in as many ways as possible. Estuarine habitats with coastal mangrove shorelines and tree roots are often important spawning and nursery territory for juvenile marine species including shrimp, crabs, and many sport and commercial fish species such as redfish, snook and tarpons. Different contributions to mangrove sediment accretion are organic detritus from the mangroves, mineral sediment from river discharge, and soil volume change/compaction [27,42,43]. Mangroves are a type of endangered tree that inhabit fringe areas between fresh and salt water systems. In southwest Florida, tremendous growth and development pressure has resulted in appreciable losses in mangrove wetlands. Mangroves are a vital ecosystem that benefit our environment, economy, and communities. They straddle the connection between land and sea and nature and humans.

Today, that number has shrunk to less than 25 million square miles (40 million square km). However, for damage assessment purposes, if considered appropriate, a standard fine could be developed, based on further analysis of the values discussed in this report. Eventually this leads to the deaths of mangrove trees. Albertas wetlands have been disappearing since late 1800s and are sensitive to water and land management. If undertaken on a sustainable basis, this activity can be supported in the long term by mangroves.
