Odds ratio estimates for the effects of tree characteristics prior to a cold storm (seed transfer distance (in units of °C), tree height (in meters), and presence of a fork, ramicorn, or fusiform rust gall on the resulting storm damage (limb or stem breaks and foliage injury). Parameters were estimated excluding nonsignificant effects. A 1° increase in seed transfer distance was estimated to increase the odds of limb or stem breaks by 7% (odds ratio = 1.07) and the odds of foliage injury by 11% (odds ratio = 1.11). A 1 m increase in height almost tripled the odds of limb or stem breaks (odds ratio = 2.85) and increased the odds of foliage injury by 26% (odds ratio = 1.26). The presence of a fork or a ramicorn more than doubled the odds of limb or stem break.
