More than 100 varieties of coffee tree breed naturally in forests, including the two kinds that are used for making the coffee we consume. According to researchers the number is “disturbing”, as wild coffee is vital for supporting the global coffee crop.About one in five of the world’s coffee plants is vulnerable to extinction, and the 60% figure is an “enormously high” one.
“If it wasn’t for wild species we wouldn’t have as much coffee to drink in the world today,” said Dr. Aaron Davis of the Royal Botanic Gardens, Kew.
A study found that 75 wild coffee species are contemplated as threatened with extinction, 35 are not endangered and little is known about the remaining 14 to consider any observations.
Additionally, it was found that 28% of wild coffee species cultivate outside shielded areas and only about half of them are conserved in seed banks.
Many of these wild coffee species are not great in taste but they may contain genes that can be used to help coffee plants become resistant in the future.
