Tree Snags for Wildlife

This is a story about the management of a landscape tree in decline, management with an underlying theme of benign neglect.

Last summer I heard the unmistakable sound of a Pileated Woodpecker hammering on a large old white pine tree near the edge of the lawn. I was thrilled to see our largest woodpecker so close to home, but also knew that its presence was a sign of a tree in trouble. Sure enough, there was advanced decay at the base of the tree and the Pileated was foraging on carpenter ants. The probability of tree failure and subsequent damage to nearby targets was high. The White Pine was a “hazard tree” and had to be removed.

My contract with a professional arborist for removal included an unusual request. I wanted to minimize the hazard – but leave a large snag for wildlife.

The decision to create a snag payed dividends almost immediately. A Pileated Woodpecker is a frequent visitor, foraging around new wounds as well as old ones.

Pitch oozing from the fresh wounds on a warm day provided an unplanned photo opportunity and aesthetic experience. The fascinating world of magnified pitch droplets kept me busy long after the woodpecker had left the scene!
