Nancy Folbre, whose 1984 paper in Economic Development and Cultural Change used to be  required reading in my development seminar has an excellent column in today’s New York Times on the economics of trees.
In her column, Folbre addresses trees as private and public goods, coordination failures in tree planting, deforestation, carbon sequestration, etc. I only dream of writing well enough so as to eventually be able to effectively address so many issues so concisely.
If you are interested in the economics of common property management regimes, Jean-Marie Baland and Jean-Philippe Platteau have a chapter in the Handbook of Enviromental Economics on the topic. Jean-Marie also has a number of other works on deforestation.
