Survival Trees of the Eastern Woodlands

摘要

Being able to identify basic trees in wilderness areas you frequent is beneficial for survival. The British Thermal Unit (BTU) is a standard unit of energy that is used to measure the amount of thermal energy necessary to raise the temperature of one pound of pure liquid water by one degree Fahrenheit. Wood should be seasoned (thoroughly dried) when used for burning as fuel or starter kindling. A good indicator that a wood's moisture content is low is if you see small splits in the ends. Another test is to knock two pieces together, as dried wood makes a distinct clinking sound, while green wood has a more subdued sound.
