Dúas das meirandes ameazas ós montes son os incendios forestais e as especies exóticas invasoras (EEI). Neste traballo de tese trátase a relación entre ambos a través da xerminación ou os compostos alelopáticos e estudáronse tratamentos mecánicos para o control das EEI. Estudáronse 11 especies, das cales 9 son EEI presentes na Galiza e norte de Portugal, entre as que destacan diversas acacias, o eucalipto ou a albizia. As diferenzas achadas na resposta xerminativa das especies poderían mudar a composición do ecosistema tras un incendio. Tamén os aleloquímicos presentes nas follas parecen determinar a xerminación, xa que as sementes poden sentir sinais os químicos do ambiente e calibrar o mellor momento para a xerminación. Con todo isto, propuxéronse medidas de control de EEI para reducir as poboación xa establecidas.
