Abstract(s)
Vivemos hoje num mundo profundamente modificado pela espécie humana. No território continental e nas regiões insulares de Portugal é possível encontrar uma grande diversidade de espécies exóticas, algumas das quais são invasoras.Desde a década de 1990, investigadores de diversas áreas e outros atores interessam-se pela problemática das espécies invasoras, quer em termos de investigação, quer de gestão e legislativo. Em 1999, a legislação portuguesa reconheceu a gravidade através do Decreto-Lei n.º 565/99, de 21 de dezembro, o qual regula a introdução de espécies não indígenas. Em 2015 entrou em vigor o regulamento n. º1143/2014, de 22 de outubro de 2014, da União Europeia, relativo à prevenção e gestão da introdução e propagação de espécies exóticas invasoras. Em 2019 sai o Decreto-Lei n.º 92/2019 de 10 de julho onde identifica mais de 200 espécies invasoras. O concelho de Góis apresenta muitas plantas invasoras, nomeadamente Acacia dealbata (mimosa). Este trabalho foca-se numa área do concelho, pertencente à Comunidade Local dos Baldios da Freguesia do Cadafaz, uma vez que é uma zona onde as mimosas ainda não têm grande expansão, sendo urgente intervir atempadamente enquanto é mais fácil atuar no seu controlo e combate.Após diversas visitas de campo, recolheram-se dados e georreferenciaram-se as manchas de plantas invasoras encontradas na área de estudo. Com esse levantamento apresenta-se um mapa onde se localizam as percentagens de ocupação das espécies invasoras, que tem um total de 162,14 ha invadidos. Na área de estudo, apenas se identificou a espécie invasora mimosa.Apresentam-se propostas de gestão, incluindo os custos e os métodos de controlo, para todas as áreas onde há presença da espécie invasora alvo e são destacadas aquelas que são prioritárias para combate no momento.
Today we live in a world deeply modified by the human species. In Portugal's mainland territory and islands, it is possible to find a great diversity of exotic species, some of which are invasive.Since the 1990s, researchers from various areas and other actors have been interested in the problem of invasive species, both in terms of research and in terms of management and legislation. In 1999, Portuguese legislation recognised the seriousness through Decree-Law No. 565/99, of 21 December, which regulates the introduction of non-indigenous species in nature. In 2015 the European Union Regulation No. 1143/2014 of 22 October 2014 on the prevention and management of the introduction and spread of invasive exotic species came into force. In 2019, Decree-Law no. 92/2019 of 10 July comes into force, identifying more than 200 invasive species. The Góis municipality has many plants of the invasive species, namely Acacia dealbata (mimosa), so this work focuses on one area of the municipality, more precisely the area belonging to the Local Community of Baldios da Freguesia do Cadafaz, since it is an area where mimosas (Acacia dealbata) do not yet have a large expansion and it is urgent to act in time for its control and combat.After several field visits, data were collected and invasive plant areas found in the study area were georeferenced. With this survey, a map is presented where the percentages of occupancy of invasive species are located, which have a total of 162,14 ha invaded. In the study area, only the invasive species mimosa (Acacia dealbata) was identified.Thus, management proposals are presented, including the costs and control methods, for all areas where there is the presence of the target invasive species and are highlighted those that are priorities for combating at the moment.
