Problem
Threatened trees
Incidence:
10% of the world's know tree species face extinction. More than 8,750 of the 80,000 to 100,000 tree species known to science were found to be threatened with extinction (from data available in 1998). This includes almost a thousand species believed to be critically endangered, with some species only known from one or a handful of individuals. Fewer than one quarter of the species found to be threatened benefit at this time from conservation measures: only 12% of these species are recorded in protected areas and only 8% of species are known to be in cultivation.
