The pixies in the picture are spending a quiet afternoon in the wetlands of Pixiedom, where their distant ancestor built a home hundreds of years before.
I've always wondered, what is the difference between wetlands, marshes and swamps? I'm about to find out. But, before I do, let me show the picture that inspired my visit to Pixiedom: 
A swamp is a wetland, and a marsh is a wetland, but not all wetlands are marshes or swamps.

A wetland is defined as any area where the land is covered by water throughout the year, or for part of the year. According to the Forest Preserve District of Will County, Illinois, a wetland may also be an area where the water table is "at or near the land, which allows aquatic plants to thrive there".

Wetlands are a gift to the environment. They are important in controlling erosion. They sequester carbon, improve water quality, and shelter about a third of the endangered and threatened species in the world. (Information about wetlands derived from the U. S. Forest Service).

The difference between a marsh and a swamp is determined by the kinds of plants that grow in the wetland. Both marsh and swamp are characterized by water. Swamps are forested, and marshes have very few, if any trees. According to the Will County Forest Preserve, "Swamps are often characterized by the type of tree predominate there". Swamps may be found all over the world, except in Antarctica.

The soil in a marsh is muddy, waterlogged. Grasses abound in a marsh. The plant root attaches to the mud. This slows down the flow of water and helps to prevent soil erosion. There are three types of marshes, according to the Will County Forest Preserve District: tidal freshwater marshes, tidal saltwater marshes and inland freshwater marshes.

My Collage
As soon as I saw 
The path I traveled to the final result, from my initial impetus, was circuitous.
At first there was a medieval village:
It was when I added a moat,
that the final picture began to take shape in my imagination. So many twists and turns on the way. As I saw the final result the idea of a blog about wetlands occurred to me. My friend, and teacher,
