Project
O projecto tem como objectivo contribuir para a aquisição de metodologias que permitam renaturalizar ou recuperar turfeiras na ilha Terceira. O projecto assenta nos princípios ecológicos da sucessão, da dinâmica e funcionamento dos ecossistemas. De facto o ponto forte deste projecto é usar o conhecimento sobre os processos da sucessão natural e os processos dinâmicos associados à diversidade estrutural e funcional para a indicação de diferentes possibilidades de metodologias de renaturalização e/ou restauração. Só com base nestes princípios ecológicos (estrutura vs funcionamento) numa escala espacial e temporal é possível obter sucesso em qualquer programa de intervenção. A abordagem a 3 diferentes escalas (paisagem, comunidades e local) contribui também para a percepção global do funcionamento destes sistemas.

The Criação do Filipe peatland complex on Terceira Island (Azores) includes a fragmented network of interconnected peatlands that have persisted over time within an agriculture-dominated landscape. This study identifies a number of human pressures including cattle grazing in and around the mire, a high population density of rabbits, high cover of exotic plant species and the presence of infrastructure (stone walls, electricity poles, etc.). The peatland complex has 44 plant species including four Sphagnum species, ten endemic vascular plants and eight plant communities. The maximum peat depth is seven metres. The peatlands receive inputs of water from streams entering at their northern margins, particularly from two pumice-extravasated cones, in addition to precipitation and intercepted fog. Accumulated water feeds other wetlands downstream. The complex shows increasing cover of aggressive and natural woody species, and water table levels are lower now than they were in 1998. Given its importance as one of the largest peatland complexes within Terceira Island's anthropic landscapes, which is partially protected by the European Habitats Directive and located within a Natura 2000 network area as well as in Terceira Natural Park, the Criação do Filipe area should be the target of an active restoration/conservation plan.

A importância da paisagem na conservação da biodiversidade em meios insulares (vídeo da apresentação).
The study central goal was to analyze secondary succession in a degraded peatland: (1) Sphagnum distribution trends and (2) successional patterns. Main study sites were adjacent abandoned pastures, where grazing was carried out in former peatland and where degradation had occurred, hereafter referred as degraded peatland. (1) Degraded peatland was mapped in 2006 (while it was still a pasture, grazed for over 30 years), and throughout the study period in 2013 (2 years post-abandonment) and 2015 (4 years post-abandonment). The baseline assessment of 2006 revealed that Sphagnum spp. were present in 7% of the area, which pointed at the resilience of the peat ecosystem. After the grazing ceased, Sphagnum cover increased to 17% and 39%, in the next 2 and 4 years respectively post animal removal. (2) To gain a general comprehension of flora and vegetation changes along the regenerative sucession, 48 permanent plots were established in the degraded peatland. In two other study sites, a further twenty plots were established, ten plots in a semi-natural peatland area where grazing ceased 30 years ago and ten others in a natural peatland. These were monitored between July 2012 and July 2015 (triannual). After 4 years, the formerly degraded peatland showed considerable recovery with a growth of Sphagnum spp. cover as well as other species like Calluna vulgaris, tending to become more similar to semi-natural and natural peatlands. Grazing cessation induced the regenerative succession that could lead to self-recovery, which, in optimal conditions, could be an alternative to active restoration in Azores.
