Creating Nesting Habitat
Dean Flicker

We are all aware that in order to sustain and improve the numbers of waterfowl, there has to be a supply of quality wetlands available. Just as important is having good nesting cover surrounding these wetlands that will give waterfowl a reasonable chance to successfully hatch a clutch of eggs that will then use the available wetlands. In many cases, the cover surrounding these wetlands is marginal at best. If you have a situation like this, there are things you can do to improve it.

Most people think that as long as you have grass around a wetland, you have sufficient nesting cover. Although this is somewhat true, these grasses may hinder ducks from taking full advantage of their egg hatching capabilities. You may refer to this as ducks not reaching 100 percent of their potential recruitment efforts.

As a hen looks for a place to nest in the spring, her primary goal is to be concealed. These days, many of our wetlands are surrounded by reed canary grass. Even though this grows tall and lush, it does not stand up to winter snows. By the time spring rolls around, the grass is flat as a pancake. This is true with other grasses as well. During the time it takes for new growth to establish itself, quality nesting time has already been lost.

So, what is the best kind of grass to plant for nesting cover? There are many different types of native and tame grasses you can choose from. Ideally, hens prefer to nest in "bunch" types of grasses versus continuous stands. One of the main reasons for this is it is easier to navigate through these grasses. If you think about how vulnerable ducklings are, you can see how bunch grass types of cover make it easier for a hen to get her brood to water after hatching.

One final thing to consider is how many different species of birds and animals are you trying to support. If you are in an area where you are trying to provide cover for pheasants as well, you should also think about what they need for brood rearing and winter survival.

In the end, you may want to consult a professional to determine what is best for you. There are different private companies, like D & M Natureworks, and public, such as the DNR, to go to for help. Using these resources may make a difference in how fast and successful your nesting cover takes.

This is one of those habitat efforts private individuals can and should do. If we could improve our nesting success by 20%, we would go a long way towards supporting our waterfowl population. Think about doing your part. Don’t leave it up to others.
