forest community.Now we know that fire is a natural agent that rejuvenates a forest.And we know that fire suppression can actually threaten the lives of healthy trees.So, today our policy is to allow natural fires to burn under close observation and to set “prescribed” fires under ...
regular discourse is usually keen to the distinction. Keeping them separate, therefore, is often more difficult for the reader or listener (especially since they sound alike when spoken quickly). Context will usually tell you if an action is being ordered (prescribed) or prohibited (proscribed)....
