The removal of trees, shrubs and other protective vegetation to make room for the development of roads and houses has increased the amount of impervious area in the lakeside landscape. Native vegetation with its deep root systems and natural duff layer act like a sponge to hold storm water runoff and associated nutrients.
Impervious surfaces result in more storm water running directly into the lake.
NPS pollution that enters lakes affects the nutrient balance of the water and creates a bottom habitat ideal for weeds to root. It can cover fish eggs and habitat as well. Revegetate or allow native landscape plants to fill in the shoreland zone and you will increase biodiversity, increase wildlife habitat and protect your property values. The best or ideal buffer for ecological and water quality value is a combination of tall trees, shrubs, groundcovers and duff. Lawn grass alone can not protect the lake and associated shoreline.
