Aerial Survey and Site Assessment

December 3, 2018

Last month we conducted an aerial survey and site assessment of approximately 6 acres of private property in the Driftless Region of southwestern Dane County, Wisconsin, surrounded by DNR land on three sides, and bordered by a county highway along the southern edge.  Although somewhat small acreage in size, the wedge-shaped property is huge with regards its natural beauty and dedication to prairie restoration by it the owners.

Our drone was flown at 250 feet AGL to collect aerial photos during leaf-off (and rather brisk) conditions, while, because of thin cloudiness, filtered sunlight allowed us to obtain good quality imagery without the distraction of shadows.  The resulting high resolution imagery will help guide the property owners with future land management decisions, including controlled burn operations and removal of invasive plant species.

 

The brief environmental site assessment report findings show that the majority soil types across the land parcel are silt loam (Sogn, Edmund, Port Byron, and Dodgeville), which are typical for the area, with corn and soybeans being the dominant crops in nearby fields.  Several threatened or endangered plant and animal species exist in the immediate and surrounding area, including the eastern prairie fringed orchid, Meads milkweed, prairie bush-clover, Northern Long-Eared Bat, and Higgins eye (pearlymussel) and Sheepnose Mussel clams.
