Humans are pretty close with conifers. Each year, millions of people around the world invite those trees into their homes for the Christmas season. But as familiar as conifers are, the fact that many of them around the world are endangered might come as a surprise.

The Global Trees Campaign, a non-profit partnership between Botanic Gardens Conservation International and Fauna and Flora International, is drawing attention to the diversity of conifer trees as well as the threats they face. There are more than 200 species of conifers around the world that are facing extinction, Emily Beech writes for the organization’s blog. The trees face trouble primarily thanks to deforestation, pests and habitat loss - not the Christmas tree trade, as some might assume.
