Bonterra Vineyards is teaming with Audubon International to help golf courses become environmentally friendly and Valhalla Golf Club, the site of the 2008 Ryder cup was the first to sign up.

Through the end of the PGA Tour season (Nov. 10) the first 100 golf courses who want to become more environmentally friendly can sign up for "Greening the Greens" at http://www.bonterra.com/greens/howitworks.aspx.

Once enrolled, Bonterra will pay for the course's registration fee to the Audubon Cooperative Sanctuary Program. The program guides courses in environmentally friendly practices, from increasing wildlife habitat around the golf course to finding natural ways to reduce pesticide and water use.

"Partnering with Audubon International was a natural fit for us. Bonterra uses a lot of the same water management and habitat strategies at its vineyard that Audubon International recommends for its golf program," said Don Freytag, Bonterra global brand director. "What's good for the Earth, is good for the Earth, whether you are producing award-winning wines or playing on an award-winning golf course."

Roughly 13 percent of the nearly 16,000 golf courses in the U.S. are currently enrolled in the ACSP program which focuses on six main areas: Environmental Planning, Wildlife and Habitat Management, Chemical Use Reduction and Safety, Water Conservation, Water Quality Management, Outreach and Education.
