Juniperus cedrus can reach impressive ages on the cliffs of the Teide National Park in Tenerife, Canary Islands. (a) The oldest juniper is at least 1481 years old and has a twisted and inverted stem, while (b) its neighbor is 1236 years old. (c) Reaching these ancient junipers is not easy, and hence, the use of advanced climbing techniques was essential. (d) As a result of the conservation measures of the Teide National Park, and of the seeds produced by these ancient junipers, the species is beginning to regain its past presence

Radiocarbon dating for the selected Juniperus cedrus individuals (JC1–JC4) growing on cliffs in the Teide National Park in Tenerife, Canary Islands. Dating was corrected considering the atmospheric δ14C variations during the last millennium, and uncertainty in dating was estimated accordingly
