Birds are attracted to fresh water ponds and man-made storage ponds that have been constructed near runways for the airports many needs. Some of them have been netted in the past to prevent birds from gaining access to the water. However, netting does not camouflage the water and therefore still attracts waterfowl. Because netting does not block sunlight, algae and weeds strive, making these areas a desirable place for the birds to roost and feed. Furthermore, netting does not last as long and is susceptible to snow and ice in cold climate.
A floating cover will camouflage the water surface and significantly reduce bird activity in and around the previously open water areas.
