How Do Trees Fare in Major Cyclones / Hurricanes?

If you are in those areas both a little north and south of the equator you probably experience major tropical storms variously called cyclones, hurricanes or typhoons, depending on where you are located.

In Australia we get cyclones while in the USA they are named hurricanes, and typhoons in much of East Asia.  All are powerful, destructive storms and it seems, getting stronger.

Loss of the local vegetation is common - with lots of leaves shredded as an initial effect of the wind damage and often massive loss of tree cover, plus broken branches and destroyed and fallen trees.

The question is asked.....how do trees cope in these massive storms?  What happens to them, and why are some much better survivors?  Following Cyclone Marcus in 2018, the Darwin local government council, no stranger to these massive storms, sought to try and detail what trees fared best and why and to develop an improved list of suitable resilient trees, and to detail those of  much lesser stability and resilience.  Earlier work detailed outcomes of the major Cyclone Tracy in December 1974 in relation to tree resilience.

More recently, the February 2019 edition of The Scientist journal has explored this much more, even experimenting with "pseudo hurricane" damage to explore redevelopment of natural forest cover.
