Can the Park District come out and trap a beaver?
Trapping requires a state permit from the Department of Natural Resources (DNR) and rarely solves the problem. It is important to learn to live with wildlife and one way to achieve this is that residents are encouraged to protect the trees in their yard by wrapping the trunks with wire.

Why aren't the pond edges being mowed?
A 10-foot buffer is maintained around the edges of the pond to prevent erosion. In addition to being cost-effective, as pond edge restoration is expensive, this buffer also deters geese. This unmowed buffer area is burned or mowed annually and invasive weeds are kept to a minimum.

Why isn't the tall grass mowed down, as it is the breeding ground for mosquitoes?
In fact, mosquito breeding does not take place in tall grass but rather occurs in shallow pools of stagnant water. Prime examples include puddles, buckets, old tires, or any container that may collect water.

When are the ponds treated for algae?
Park District ponds are treated on an as-needed basis. In general, the algae surface area coverage is not to exceed 25% of a pond's surface. During treatment, chemicals are applied to the ponds that kill the surface algae; the algae continue to die over the next few days and subsequently turn brown. Rain following the treatment pushes the dead algae below the surface to the bottom of the pond.

Why are there algae present in the pond?
Algae result from a combination of organic matter, such as dead leaves, animal waste, grass clippings and fertilizer, and low oxygen levels. Without adequate oxygen levels the organic matter is unable to be decomposed and consequently provides nutrients for the algae to thrive.

What is being done about the sand wasps in the playgrounds?
The Park District does not treat for sand wasps and Orkin will not either. The area is signed to alert residents to the wasps' nesting and they will be gone in 7 to 10 days. In addition to their short nesting period, sand wasps are typically non-aggressive as well.
