I restored a salt marsh one time, on the Wertheim National Wildlife Refuge. Dredged in fill to get elevations up in areas that eroded. Removed phragmite which is some of the nastiest stuff ever. It was an awesome opportunity and experience.

That sounds really cool, and much needed. Thank you!

I was needed. There was this grass that grew only within a 2" elevation of sea level (4 to 6 inches elevation) and the area was washed out by Hurricane Sandy. It turned into a swamp infested with mosquitos because some areas just wouldn't drain. So we moved several thousand cubic yards of material to infill, cut new runnels and channels, made sure there was no ponding, and them finished other areas with native seeds and the craziest SWPPP program I have ever been a part of. It enjoyed every minute of it.

You are welcome.

An area of salt marsh twice the size of Singapore has disappeared since the turn of the century, NASA scientists determined by analyzing satellite images from around the globe. Severe storms were partially responsible for the loss, which resulted in “significant” carbon emissions, according to a recent study based on the maps.

The study, published in the journal Nature in late November, showed that the world lost 2,733 square kilometers (1,055 square miles) of marsh over the 19-year period between 2000 and 2019 and recovered 1,278 km2 (493 mi2), some as a result of restoration by people. This resulted in a net loss of 1,453 km2 (561 mi2). Globally, salt marshes declined at a rate of 0.28% per year, according to the study.

Previously, up-to-date information on the rates and “hotspots” of salt marsh loss at the global level was limited, as were estimates of the resulting carbon emissions, Anthony Campbell, the paper’s lead author, told Mongabay in an interview. Past estimates suggested much higher salt marsh losses of between 1% and 2% per year.

Marshlands and other help control flooding. They can reduce the impact of storm surges during hurricanes.
