Good flexibility such as found in some palms with thin flexible stems.
Good well-developed root system – preferably ones with a good taproot and where the roots haven’t been cut on one side by road works or something similar.
Ease of defoliation, i.e. the ability to lose leaves quickly and so offer little resistance to the wind, many eucalypts lost leaves quickly.
Plants with fine leaves offer little resistance. Some examples are Leptospermum, Bottlebrushes and Poinciana, or they may appear leafless as in She-oaks.
Open branch system as in the Sea Almond and other species of Terminalia, likewise the Milky Pines (Alstonia spp.). These allow the wind to pass through easily.
Lack of a dense top heavy canopy or crown.
Healthy trees, vigorous growth, no termites. Slow growing trees are often the best.
Golden cane form a flexible debris-catching barrier, Pandanus remained standing. Aerial roots on Ficus gave good support.
Trees without a dense canopy, trees with fine leaves and open branch systems offer little wind resistance
