Relatório de estágio sobre a intervenção pedagógica realizada nas Escolas Básicas do 1º Ciclo com Pré-Escolar Eng. Luís Santos Costa e da Ajuda

O presente relatório, é o resultado do trabalho desenvolvido na unidade curricular de Estágio e Relatório do curso de Mestrado em Educação Pré-Escolar e 1º Ciclo de Ensino Básico. A componente de estágio teve lugar entre os meses de setembro e dezembro de 2012, com um total de 100h em cada uma das valências. A intervenção pedagógica em Pré-escolar decorreu na Escola Básica do 1º Ciclo com Pré-Escolar Eng. Luís Santos da Costa e, sendo que a de 1º Ciclo foi realizada na Escola Básica do 1º Ciclo com Pré-Escolar da Ajuda. Este trabalho encontra-se dividido em três partes, sendo que no primeira é feita uma abordagem teórica considerando autores e bibliografia de referência. As segunda e terceira, referem-se à intervenção educativa, nomeadamente aspetos referentes à contextualização de cada uma das valências, a abordagem às atividades e conteúdos desenvolvidos. Concluo o presente relatório com uma reflexão final expressando a minha opinião pessoal sobre a intervenção pedagógica bem como a contribuição desta para a minha formação pessoal, profissional e social.

Evolution of the landscape of Madeira Island: long-term vegetation dynamics

The aim of this thesis was to evaluate historical change of the landscape of Madeira Island and to assess spatial and temporal vegetation dynamics. In current research diverse “retrospective techniques”, such as landscape repeat photography, dendrochronology, and research of historical records were used. These, combined with vegetation relevés, aimed to gather information about landscape change, disturbance history, and vegetation successional patterns. It was found that landscape change, throughout 125 years, was higher in the last five decades manly driven by farming abandonment, building growth and exotic vegetation coverage increase. Pristine vegetation was greatly destroyed since early settlement and by the end of the nineteenth century native vegetation was highly devastated due to recurrent antropogenic disturbances. These actions also helped to block plant succession and to modify floristical assemblages, affecting as well as species richness. In places with less hemeroby, although significant growth of vegetation of lower seral stages was detected, the vegetation of most mature stages headed towards unbalance between recovery and loss, being also very vulnerable to exotic species encroachment. Recovery by native vegetation also occurred in areas formerly occupied by exotic plants and agriculture but it was almost negligible. Vegetation recovery followed the successional model currently proposed, attesting the model itself. Yet, succession was slower than espected, due to lack of favourable conditions and to recurrent disturbances. Probable tempus of each seral stage was obtained by growth rates of woody taxa estimated through dendrochronology. The exotic trees which were the dominant trees in the past (Castanea sativa and Pinus pinaster) almost vanished. Eucalyptus globulus, the current main tree of the exotic forest is being replaced by other cover types as Acacia mearnsii. The latter, along with Arundo donax, Cytisus scoparius and Pittosporum undulatum are currently the exotic species with higher invasive behaviour. However, many other exotic species have also proved to be highly pervasive and came together with the ones referred above to prevent native vegetation regeneration, to diminish biological diversity, and to block early successional phases delaying native forest recovery.
