Resumo: | Rivers and streams in Portugal are in poor ecological condition. River restoration programs are therefore seen as essential. It is well established that the beaver is an important tool for improving the ecological state of fresh water habitats. This study aims to determine the potential to use beavers has a tool in future river restoration programs. The work compares, from an economic and environmental perspective, an active management approach in the form of traditional river restoration actions and a passive management strategy in the form of beaver reintroduction. First, a brief overview of the conditions for the European beaver to return to the Portuguese landscape is presented. Second, an economic estimation based on the potential to save on habitat restoration costs, beaver management expenditures and the funds required for a reintroduction program is provided. These estimates are compared with the APA 2018-2020 river restoration program. Third and lastly, the likely large-scale landscape effects are analysed based on documented dynamics for the specie. The results indicate that the conditions exist for the beaver to return to Portugal. The benefits associated with the specie outweigh the costs and the landscape effects are broadly positive. The beaver, besides saving costs in river restoration programs, creates conditions for wildlife to thrive, delivers a wide range of ecosystem services and develops a landscape more resilient to climate change. |

Vários estudos demonstram que o castor é uma ferramenta importante para melhorar o estado ecológico dos habitats de água doce. Este estudo visa determinar o potencial dos castores para futuros programas de restauro fluvial. O trabalho compara, de uma perspetiva económica e ambiental, uma abordagem de gestão ativa na forma de ações tradicionais de restauro de rios e uma estratégia de gestão passiva na forma de reintrodução de castores. Em primeiro lugar, é apresentado um breve panorama das condições para o castor europeu regressar à paisagem portuguesa. Em segundo lugar, é feita uma estimativa económica com base no potencial de poupança de custos relacionados com o restauro de habitats, despesas de gestão conflitos e os fundos necessários para um programa de reintrodução. Essas estimativas são comparadas com o programa de restauro de rios e ribeiras da APA que decorreu de 2018 a 2020. Em terceiro e último lugar, os prováveis efeitos na paisagem natural são analisados com base em dinâmicas documentadas para a espécie. Os resultados indicam que existem condições para o castor regressar a Portugal. Os benefícios associados à espécie superam os custos e os efeitos na paisagem são amplamente positivos. O castor, além de poupar custos em programas de restauro fluvial, cria condições para a vida selvagem prosperar, fornece uma ampla gama de serviços ecossistémicos e desenvolve uma paisagem mais resistente às alterações climáticas.2021-01-07T15:01:17Z2020-12-03T00:00:00Z2020-12-032020-11info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10071/21154TID:202559564engVeríssimo, Daniel Alexandre Azevedoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-09T17:47:53Zoai:repositorio.iscte-iul.pt:10071/21154Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:23:17.426815Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
