Global Survey of Ex situ Conifer Collections highlights the need for increased conservation action

Global Trees Campaign -

A Global Survey of Ex situ Conifer Collections has analysed how well represented threatened conifers are in botanic garden and arboreta collections around the world and highlights priority taxa for conservation action.
