Phytosociology

  • Cisto ladaniferi-Genistetum hystricis
  • Lavandulo sampaianae-Cistetum populifolii

Relations with other habitat types

Had they not been cleared and eroded, the soils occupied by this scrub would harbour woodlands of the T21 block, replacing (not without transitional communities akin to those admitted by EUNIS as S51C [“Low ericaceous maquis"]) the heaths of unit S42y in the most markedly submediterranean areas of the ecoregion. S51D2 (“Central Iberian tall cistus maquis") would be the most detailed EUNIS equivalence. The recognition of S51E (“Low Cistus maquis") might be warranted in some cases, but more empirical data is needed.
