Resumen
[En] Fire and pre- or post-fire management practices shape the distribution and richness of plant species. Here,
the effects of pre- and post-fire management on vegetation recovery were studied at different times, up to 18 months
after a wildfire. Two months after a 2015 wildfire, 18 study plots were established (three 4-m2 plots for each treatment), vegetation regrowth was monitored and vegetal species richness (S), evenness (IT), density (D), diversity (H0) and maximum diversity (HMax) after 2, 10 and 18 months. The treatments were (1) control, unaffected by 2015 wildfire; (2) no treatment (NT), burned in 2015 wildfire and not managed; (3) managed in 2005 and burned in 2015 (M05B); (4) managed in 2015, 2 months before
wildfire (M15B); (5) cut and manual removal after the 2015 wildfire (CR); (6) cut and no trunk removal randomly
deposited on topsoil after the 2015 wildfire (CL). All the treatments were carried out in a Pinus halepensis Miller
forest. At 10 and 18 months after the wildfire, vegetation recovery was greater in NT, CR and CL plots than in M05B
and M15B the plots. By 18 months after the wildfire, Brachypodium retusum (Pers.) P. Beauv. and Rosmarinus
officinalis L. were still dominant, especially in M15B, corroborating the belief that pre-fire treatment reduced
ecosystem resilience and vegetal recovery compared to the NT and post-fire managed plots. Richness was significantly
lower 10 months after wildfire in control plots, and IT was significantly higher in that inventory than previously in
M15B. Eighteen months after the wildfire, H0 was significantly lower in M15B. Ten months post-wildfire, HMax
was significantly lower in the control plots. Eighteen months after the wildfire, HMax, was significantly higher
in CR, CL and M05B than in the control and M15B plots. Overall, pre-fire management was detrimental to post-fire
vegetation recovery, while manual post-fire management proved beneficial.
