Salt marshes occur worldwide, particularly in middle to high latitudes. Thriving along protected shorelines, they are a common habitat in estuaries. In the U.S., salt marshes can be found on every coast. Approximately half of the nation's salt marshes are located along the Gulf Coast. In addition to this most of the worlds salt marshes are found in the UK and Europe with the majority of these countries exploiting the area for salt production.
These intertidal habitats are essential for healthy fisheries, coastlines, and communities—and they are an integral part of our economy and culture. They also provide essential food, refuge, or nursery habitat for more than 75 percent of fisheries species, including shrimp, blue crab, and many finfish. 
Salt marshes also protect shorelines from erosion by buffering wave action and trapping sediments. They reduce flooding by slowing and absorbing rainwater and protect water quality by filtering runoff, and by metabolizing excess nutrients.

14:45- I am about to do thee challenge video for thee group presentation. Max is looking for pictures that show different impacts on salt marshes due to human involvement. Hamza is researching tourist impacts and Patrick is telling us what to do.

15:00- We still haven’t finished the challenge video, whilst I was preparing for it we were rethinking what we were going to do. Whilst we were outside Patrick, Hamza and Jachym were establishing solutions for our main question.

15:01- We are now on a break for 10 minutes.

15:11- Break has ended.

15:19- The challenge video has been finished whilst the others have done the solutions. We are now all going to write our individual reflections of the task.

15:24- We have completed the student reflections, well I haven’t but that is because I have spent the last 5 minutes trying to upload a video.

15:30- We are done.
