Wildlife trees, traditionally called snags, are said to be quite important to the ecosystem of an old growth forest. While the tree itself is dead, inside, it provides shelter for a multitude of animals, insects and other plants. They're thought to be so important that at times, such trees are left behind when logging is performed. Unfortunately, loggers don't like to work with them around and legitimate reasons too, they also were known as widow-makers for their propensity to tumble and cause injury or death. So the tussle continues where at least now, if a wildlife tree is deemed worthwhile to a local ecosystem, it is kept with a 50m no-cut zone.
In Kimberly, I saw a card that described how the widows of loggers would take the their deceased husband's boots and turn them into makeshift flowerpots as a memorial. Seems a little grim now doesn't it? Those cute little boot/shoe pots in the windows of cozy little homes.
