Forestry: the science, art and practice of managing and using for human benefit the natural resources that

The source is Canada's B.C. Forestry.  The look similar to the definitions that I learned in forestry school
many years ago.  The Society of American Forestry has a publication titled "Forestry Terminology".  You can
buy it from them.  The edition that I have (1958) defines forestry as the scientific management of forests
for the continuous production of goods and services.  The B.C. one is more up to date than my glossary.
