According to history, the surname of Lin had one of the most interesting origins and indeed it has something to do with the forests, as the character represents.
During the Shang Dynasty, there was a honest official Bi Gan who served the tyrant King Zhou (Shang Zhouwang) faithfully. Countless times he advised his cruel king to change his ways and rule with benevolence. For his efforts, Zhou had Bi Gan's heart dug out to entertain his concubines. Upon learning her husband's fate, Bi Gan's pregnant widow fled and sought refuge in the deep forests. After Zhou was deposed, new King Wu (Zhou Wuwang) sought out the widow and bestowed the surname of Lin to the newborn child in honour of Bi Gan.
