From: Can mixed pine forests conserve understory richness by improving the establishment of understory species typical of native oak forests?

HOF-derived response curves of understory species (including tree regeneration) and understory richness relative to the percentage (%) of basal area (G) of Pinus pinaster; the best HOF model according to the AIC criterion is showed. Graphs separated for clarity accordingly to different species-response groups. Pinus sylvestris monospecific plots (PS); Pinus pinaster monospecific plots (PP); Mixed plots of both Pinus species (MM). Species codes: Agca (Agrostis castellana Boiss. & Reut), Aica (Aira caryophyllea L.), Aruv (Arctostaphylos uva-ursi (L.) Spreng), Cavu (Calluna vulgaris (L.) Hull), Cila (Cistus laurifolius L.), Defl (Deschampsia flexuosa (L.) Trin.), Erar (Erica arborea L.), Erau (Erica australis L.), Hysp (Hypnum spp.),Juox (Juniperus oxycedrus L.), Pipi (Pinus pinaster Ait.), Pisy (Pinus sylvestris L.), Pomo (Potentilla montana Brot.), Ptaq (Pteridium aquilinum (L.) Kuhn), Qupy (Quercus pyrenaica Willd).
