Regeneración post-incendio de la encina en pinares de repoblación mediterráneos

摘要: Leverkus, A.B., Castro, J., Rey Benayas, J.M. 2014. Post-fire regeneration of the Holm oak in Mediterranean pine reforestations. Ecosistemas 23(2): 48-54 . Doi.: 10.7818/ECOS.2014.23-2.07 The extraction burnt wood is a common practice after wildfire, yet its effects on recolonisation by Quercus species are poorly known. We established an 18-ha plot reforestation Sierra Nevada (S Spain), with three experimental wood-management treatments: Salvage Logging (felling trees, chopping off main branches, piling logs, and masticating remaining branches), Partial Cut 90 % trees without further actions), Control (no actions taken). Some clusters pines survived within limits were left standing (totalling 1.5 ha), adjacent to some unburnt, acorn-producing oaks ( ilex subsp. ballota) from which biotic dispersal occurred. monitored emergence, survival, size seedlings for seven years. found 801 first year, corresponding either post-fire resprouts or acorns dispersed right fire before treatment implementation. After implementation, 447 emerged throughout plot, likely due European jays Garrulus glandarius ): 62.9 under live 37.1 rest plot. Emergence was greatest during factor lost importance later years, as acorn became more directed towards pines. Seedlings had greater survival but lower growth, competition nutrients, light, water. conclude that small patches survive fire, well dead can attract dispersers that, case surviving pines, second disturbance will be needed free recruited competition. Management practices favour these structures aid natural recovery ecosystem.
