Similarly, how are salt marshes threatened?
Current threats to salt marshes arechanges to natural hydrology, pollution, coastal development,fill/improper marsh elevations, and non-native/invasivespecies.
Furthermore, what are some threats to wetlands?

Threats to wetlands- Development: Floodplain development often directly impactswetlands by removing vegetation (increasing bank erosion), andfilling or draining wetlands for building sites.
- Grazing: Overgrazing harms wetlands through soil compaction,removal of vegetation, and stream bank destabilization.
What happens when a wetland is destroyed?
Today, wetlands degradation anddestruction is occurring more rapidly than in any otherecosystem. Wetlands destruction has increased flood anddrought damage, nutrient runoff and water pollution, and shorelineerosion, and triggered a decline in wildlifepopulations.Why do we destroy wetlands?
Wetlands are often underappreciated because theyare viewed as being more valuable for their water and undevelopedland than the ecosystem services they provide. They are oftendrained to make room for agriculture or human settlements. And anywetlands nearby left untouched may lose their own water tothis development.How can we prevent wetland destruction?
