Summary
Micro-woodlands of small trees or tall shrubs up to 10 m tall, dominated or co-dominated by taxa of the genus Juniperus L., all endemic to Macaronesia’s archipelagos: Azores, Madeira and the Canaries. Four distinct taxa dominate several distinct subtypes of the habitat G3.9c, each with specific sinecological traits, biogeography and floristic character (no common shared characteristic infrageneric taxa among them); Juniperus turbinata subsp. canariensis (the Canaries and a single location in Madeira), Juniperus cedrus subsp. cedrus (the Canaries), Juniperus cedrus subsp. maderensis (Madeira) and Juniperus brevifolia (Azores). The five subtypes are:
1. Juniperus turbinata subsp. canariensis habitats of the Canary Islands (Mayteno canariensis-Juniperion canariensis). Tall shrublands dominated by hard leathery leaves or scaly-leaved plants in low altitude infra-thermomediterranean semi-arid to dry localites, on thin mediterranean volcanic rock-derived soils (leptosols or thin cambisols). Dominated or co-dominated by J. turbinata subsp. canariensis, Olea europaea subsp. cerasiformis, Rhamnus crenulata and Maytenus canariensis; secondarily also by Euphorbia bertholothii, Euphorbia wildpretii, E. atropurpurea, Pistacia atlantica, P. lentiscus, Hypericum canariense and other characteristic shrubs can be locally dominant (see

Conservation and management needs
For the very rare variants, the continuous monitoring of juniper population status is paramount. Replanting from cultivated plants (botanical gardens, etc.) might be a necessary option in the very small depleted locations (1.2.measures needed and 3.1. Restoring).

Extent of Occurrence, Area of Occupancy and habitat area
Extent of Occurrence (EOO) (Km2) | Area of Occupancy (AOO) | Current estimated Total Area | Comment | |
---|---|---|---|---|
EU28 | 582350 | 62 | 530 | |

EOO = the area (km2) of the envelope around all occurrences of a habitat (calculated by a minimum convex polygon).
