Homeowners are generally unaware of many of the various circumstance that can make their trees hazardous.
If time is taken to look most people can see obvious structural problems as major decay in the main trunk of a tree. Still, the vast majority of problems leading to structural failure are not easily recognizable to the layman.
For example, genetic flaws, such as multi trunk trees like Bradford Pear, will lead to major failure as the individual trunks grow in girth and eventually push each other off.
Internal decay, which may only show a small fruiting conk on the bark, can be digesting the structural cellulose inside the tree.
