Ford Motor Co.'s environmentally friendly approach to manufacturing at the 600-acre Rouge Center has been benchmarked by other automakers, including General Motors and Toyota.
Ford execs say the new green spaces and other techniques used at the Rouge are kinder to the environment and also save money.
But there are better signs the approach is working.
The 10.4-acre "green" roof on the new truck factory that builds the F-150 pickup is covered with sedum plants. The roof is now home to several species of birds, including Canada geese, which usually prefer parks and golf courses.
And the wetlands right outside the factory, which are fed with rainwater runoff, are big enough to host a growing duck population and other critters.
It has become a little eco system because the ample wildlife that enjoys the green habitat also has attracted a coyote.
