WebWindthrow risk is also associated with the ratio of tree height to tree diameter (H:D) and the H:D ratio is often used as an index of stability (Navratil, 1995, cited in Wang et al., 1998). Trees with a H:D ratio above 80 are most suscepti-ble to damage by wind (Wonn and O’Hara, 2001). Tree species differ in terms of their vulnerability to storm WebSep 30, 2024 · At each site, we recorded all trees with a diameter at breast height (DBH) ≥ 10 cm along transects, capturing the range of windthrow severity from old-growth to highly disturbed (mortality > 60%) forest.
