Management of neophytes in protection: an example from Italy.
This paper reports the study at the protected area in Bosco Fontana in Italy, where the elimination of alien tree species was used to improve habitat structures typical of old forests. In this area, differentiated strategies were developed for the red oak and the hybrid poplar, which take into account the ecology of each species. It is suggested that the the eradication of alien trees in protected areas should be preceded by detailed planning. First and foremost, it is about understanding the regeneration strategies of the species that need to be removed. Depending on the ecology and age or stage of development of the species to be sampled, mechanical and chemical control methods are available which can be used individually or in combination. Further, the respective legal framework conditions must be taken into account. The experiments carried out in Bosco Fontana showed that species of trees that are combated can also be used to promote biodiversity. Thus, the hybrid species were transformed into habitat trees, and the red oaks were used for dead wood enrichment, whereby very different dead wood qualities could be created.
