The importance of maintaining marshes has been well established, but Rosemary explains that there are other kinds of "wetlands" that require protection, too.

Now that summer is underway, many of us are thinking water. Being in it, on it, or beside it is a lovely way to spend a day. And humans aren’t the only ones who have a thing for H-2-O. Nearly every animal, insect, and bird needs water to survive. Of course.
Often they also need the areas around our lakes, rivers, and streams almost as much. The plants that hug the edges of various water-bodies form some of the most important habitat for wildlife. Scientists call it the “riparian zone” and as you can guess, it’s often threatened by human activities.
People who live on a lake, for example, very often want to enjoy their expensive views, as in unobstructed by trees. Without realizing the damage they can cause, they often clear every shrubs and tree right to the water-line. This not only removes protective cover for wildlife, but also takes away an important natural buffer. That vegetation absorbs rainwater and helps keeps pollutants from flowing into the lake.
What also happens when all those shade-sharing shrubs and trees are weed-whacked away is that water temperatures increases. While you and I might not mind a slightly warmer swimming hole, believe it or not, several species of fish just can’t stand it. The native brook trout for example, can only survive in cool, clean waters.
Luckily, people are recognizing the importance of riparian areas. Better laws are being put in place to protect this valuable resource. And believe me, it’s valuable for more than just songbirds and dragonflies. Want a real life lesson on the consequences of not enough riparian habitat? Just take a look at the flooding out in the mid-west a few weeks ago.
