As I've traveled around the country during the past several years on our Natural History Eco-Tours and family adventures, I've had the opportunity to meet and talk to several different outdoorsman. I recently met the biologist for the "Northern Trail" at the Minnesota Zoo, who manages the wolf, tiger and other exhibits. Then I met the Outdoor Education Manager for the Three Rivers Park District in Hennepin and Scott Counties of Minnesota (which includes the recognized IBA [Important Birding Area] of Murphy Hanrahan Park), and an attorney with the state of Minnesota who writes legislation for threatened or endangered species. And with all of them - our conversation got around to habitat and wildlife conservation.

As a result of talking to Minnesota's State Farmland Wildlife Manager, Al Berner, about such various species as deer, ducks, pheasants, turkeys, sharp-tailed grouse and prairie chickens - I've come to realize that the loss of habitat for many game species also means loss of habitat for many non-game species, such as insects, fish, small mammals and songbirds. In other words what is good for the game birds, is also good for the songbirds and other types of birds.

While I was talking to Al he impressed upon me the need for habitat restoration such as Conservation Reserve Program lands, and other habitat conservation, such as preserving or maintaining existing prairie and wetland habitat. Many upland bird (game) species, such as pheasants, sharp-tailed grouse, prairie chickens, gray partridge, and even turkeys, need large areas of prairies, meadows, swamps, sloughs, fens, oak savanna, etc., for breeding and nesting habitat. Those areas also support Dickcissel, Bobolink, Meadowlark, and various species of sparrows. Many of those areas, because they are often on fairly level ground that might not be suitable for farming, are destroyed to make room for business complexes and housing. I see we just lost an area where I used to photograph Dickcissels in 2007, to farming.

To those outdoorsmen and nature lovers who don't hunt, this might not seem like a concern, except that those areas are also prime habitat for many species of birds, small animals, reptiles, amphibians, fish, wildflowers and other plants. As I lead our natural history tours I've begun noticing the wide variety of native plants, wildflowers and birds that use wetlands, meadows and prairies. I've also begun to realize how much of their habitat is destroyed by human encroachment, in the name of progress.

After watching several programs on the Discovery, History and Animal Planet channels, I've come to realize the importance of wetlands (that serve as important habitat for birds) as barriers to the negative effects of storm surges and flooding. Cattail, sawgrass, rushes and other wetland plants have the ability not only to reduce erosion due to flooding and storm surges, they also have the ability to reduce the harmful effects of pesticides, herbicides and fertilizers on the water and plant life, which provides needed habitat for the wildlife (including birds).

When rain falls on land covered with natural vegetation, the plants can slow the flow of run-off until it has a chance to sink into the ground, resulting in only a 10 per cent run off. However, when rain falls on a parking lot, 55 per cent of the water can run off into local brooks, creeks and wetlands; and from them into larger bodies of water.

Run-off water may contain a variety of contaminants including oil, grease, heavy metals and sediments, plus harmful herbicides and pesticides, and fertilizers containing phosphorus, which can promote the growth of algae, often resulting in mass of green scum floating on the surface of the water, and result in algae "blooms" which often turn the water red-brown or blue-green.

Any of these conditions can result in less sunlight entering the water, causing less photosynthesis by native aquatic plants, resulting in less oxygen content in the water, and the possible spread of less beneficial and /or non-native and invasive plants, which do not help maintain the balance of the eco-system.

The preservation or creation of shallow swamps, sloughs, ponds or lagoons, between run-of water and/or streams, and deeper bodies of water, with their native vegetation, can greatly increase the natural filtration of water. Plants such as cattails, saw grass and sedges that may have extensive root systems which survive in shallow water, not only slow the speed of the water, but also trap sediments, and can filter out and use some of the contaminants that may cause a negative impact on the ecosystem plants in deeper waters.
