Cascais Rewilding
Nature tourism, local communities and herbivore reintroductions
Cascais Rewilding is part of the Sintra-Cascais Park. In 2008, it was transformed from an abandoned agricultural land into an attractive park, as well as a working farm. Ecological restoration focuses on the historical legacy of this rural landscape and includes natural grazing. Nature based tourism and production of local products is part of the project.
This area is strongly influenced by people, whether in the presence of villages or roads that in some way fragment the territory. As it is a peri-urban area, human pressure is strong, particularly in activities and adventure sports that cause some disturbance. With the abandonment of agriculture in the 60’s and the introduction of exotic species to “contain” the advance of the dunes, the territory became vulnerable to wildfires and the proliferation of exotic invasive species, in particular species that are favored by the cycle of wildfires (ex.: Acacia spp.). A significant part of this landscape reflects, in terms of floristic diversity, a “natural” selection promoted by the cycle of 4 to 6 years wildfires that benefit plants with reproduction characteristics to the detriment of seminal plants.
The recovery of the ecosystem balance and natural dynamics is crucial for the management of the territory in a sustainable and perpetual way. For this, the introduction of herbivory with key species will naturally shape the landscape and in the long term reach a balance, providing opportunities for education and environmental awareness for who visit the Sintra-Cascais Natural Park, but also safe for who live in the region, as well as the opportunity to enhance economic and social dynamics that promote recognition of the added value of living in a territory where population cohabits with wildlife.
• A place where nature re-establishes its natural dynamics and enhances nature tourism.
• Recover and restore the landscape vegetation and grazing mosaic, resilient to climate change pressures and impacts.
• Preservation and restoration of natural habitats and endemic species.
• Historical heritage recovery and preservation.
Two rewilding areas were established with free herds in a process of natural grazing. Peninha a 60-ha area combines Garranos wild horses and Miranda Donkeys to maintain the high-altitude pastures, reduce biomass, avoiding wildfires that usually occur in this area. In another area with 120 ha, Sorraias Wildhorse, Miranda Donkeys, and Roe deer were released through a mixed natural grazing process.
In 2021 we’ve concluded the eradication of fast-growing eucalyptus to allow natural regeneration of oak Portuguese forest, it took 5 years of gradual cutting to minimize fauna and flora impacts. A new forest of Portuguese oak (Quercus faginea) it´s prospering naturally helped the combination of wild herd and birds that help to spread the acorn.
In addition, we have been focused in managing and controlling alien invasive species, mainly flora but in the future also freshwater fauna. Two new lagoons were restored to allow habitat condition for birds but also to reptiles such Mediterranean pond turtle, Mauremys leprosaa (VU), and freshwater fish Iberochondrostoma lusitanicumnew (CR) and Squalius pyrenaicus (NT) that were reintroduced, a new pond will be restore in nest year.
We have gained support from the community and raised awareness about the project and its goals, resulting in increased number of visitors, as well as in nature activities, workshops.
To make this project a success we needed to gain control of the property, long time submitted to vandalism, this was our major obstacle. For 4 years we fought against illegal hunters, all-terrain vehicle drivers, illegal dumping, and other similar situations. Only after solving those problems, we could develop the project.
We started restabilizing this area's habitat connectivity and reintroduction of natural grazing with the farm animals like sheep, donkeys, and horses, reseeded pastures, planted native trees, and shrubs, and reactivated the landscape. Gradually we gain knowledge and confidence that allow us to push forward the project, which becomes more ambitious regarding the reintroduction of wild and semi-feral animals.
The community naturally started to come and look inside the park, asking for more information about the project. By then, we knew we got their attention. That was a small but very important achievement. People remembered how this land looked before and how it was managed, and they associated it with our work.
We want to re-establish the natural processes in Sintra-Cascais Natural Park, Cascais municipality, the introduction of wild animals is a great challenge, whoever the Quinta do Pisão success worked as a pilot, which helped to gain community recognition and political support.
With this experience and political support, we are expanding the area of rewilding, our main goal it’s to link the public and private land and create a greater area of about 2300 ha.
