Stora Enso has published the latest edition of its Sustainability News newsletter, with a special focus on the definition of old growth woodland.

This, says the company, describes how “even the uninitiated may learn to identify the most common characteristics of old-growth forests”.

The newsletter includes a comparison of different woodland criteria and the views of Mr. Olli-Pekka Turunen, a specialist used by WWF Finland in screening potentially valuable forests in Northern Finland.
