Dr. Max Terman, Tabor College, Hillsboro, KS, discussed enhancing wildlife on your course using Prairie Dunes as his model. This is my all time favorite golf course and makes a great but mostly unattainable model. He noted that ideally golf courses would serve as stepping stones between ecological areas. Although mostly they are oases in the middle of urban sprawl. Salamanders and other amphibians are the best indicators of an environmentally friendly area.
Birds of prey are another good indicator of environmental health.
Deer can destroy the environment. No, he didn't say the latter but after listening to him that is what I had to conclude. Dr. Gail Schumann, pathologist for U. of Mass., presented highlights from the research of other turf pathologist around the country. And if I got this correct was obtaining some acceptable Dollarspot control with Companion 1 at 4 oz. The fact this is a spore forming bacteria make it well suited for shelf life and application through sprayers or injection systems.
