Another less biased source for information on best practices is Penn State's Marcellus Electronic Field Guide which provides information on ecological concepts, pre-development issues, invasive plant management, restoration and goals, revegetation, restoring and creating wildlife habitat, sample leases looking at natural resource considerations, and best management practices. There is also an area for people to subscribe to a forum on various issues. A picture gallery is provided to demonstrate what different elements of drilling infrastructure and landscape change look like, and users may upload their own photos as well.

With regards to Natural Gas Flaring and Venting, the Energy Information Adminstration published best practice guidelines in 2004.
