An ambitious project implements concrete conservation actions to rewild the C\u00f4a Valley in Portugal, which acts as an important natural corridor for wildlife. An essential element of the project is the restoration of trophic chains – how does tracking the movements of Griffon Vultures help achieve this goal? <\/p>\n\n\n\n

The Greater C\u00f4a Valley is an area in Northeastern Portugal, close to the border with Spain, with rich biodiversity and varied landscapes. The river gorges, oak forests, rocky heathlands and scattered fields constitute a spectacular mix between the Douro river and the Malcata mountain ranges. Last year, the project \u201cScaling Up Rewilding in Western Iberia<\/a>\u201d started in this area, with the goal of developing a coherent ecosystem and strengthening the wildlife corridor of the C\u00f4a Valley. An essential element of rewilding this valley is the restoration of trophic chains. At the moment, local populations of Griffon Vulture (Gyps fulvus<\/em>), Egyptian Vulture (Neophron percnopterus<\/em>) and Cinereous Vulture (Aegypius monachus<\/em>) are affected by low availability of food sources in the region, an issue which so far has only been mitigated by a network of artificial feeding stations (so-called \u201cvulture restaurants\u201d). <\/p>\n\n\n\n

Promoting the restoration of tropic chains<\/strong><\/p>\n\n\n\n

One of the aims of the project is to increase the availability of carrion in the area by setting up a network of local farmers who are allowed to leave the carcasses of livestock (sheep, goats, pigs, horses or donkeys) on designated areas of their properties, something which so far has not been done in Portugal. In order to set up this network to improve the availability of carcasses in a more natural way – more diverse in terms of location and time – and also to be able to evaluate the success of this measure, it is important to know how scavenger birds from the colonies of the C\u00f4a Valley and the Douro International Natural Park are currently using the landscape and the available feeding resources. <\/p>\n\n\n\n

Understanding feeding ecology with GPS tracking\u00a0<\/strong><\/p>\n\n\n\n

To that end, Griffon Vultures, as the most abundant and widespread of the three vulture species, are being tagged with GPS transmitters in the C\u00f4a Valley, and their movements are being monitored. This is providing critical information about the resources that Griffon Vultures use for feeding and where they feed. Understanding the feeding ecology of the scavengers in the region will provide valuable information regarding priority areas where food availability should be improved. Moreover, in four years\u2019 time it will be possible to check how the situation has changed regarding the way in which Griffon Vultures use the landscape and feed. <\/p>\n\n\n\n

Competition: Win a GPS tag\u00a0<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Ecotone Telemetry<\/a> generously donated a GPS tag to the Vulture Conservation Foundation (VCF), and the VCF decided to donate it to help support the monitoring and conservation actions of another Griffon Vulture or Cinereous Vulture project in Europe. In early 2020, we carried out the competition<\/a> together, and we are happy to announce that Rewilding Portugal<\/a> is the winner! Their project, Scaling Up Rewilding in Western Iberia, will now be able to tag one more Griffon Vulture in the C\u00f4a Valley, which will provide valuable additional data. This new transmitter will be used in May of this year, when the next group of Griffon Vultures will be tagged. We will communicate in the future about the vulture that will be tagged and its movements. You can stay tuned on the updates by signing up to our newsletter.<\/p>\n\n\n\n

Scaling Up Rewilding in Western Iberia<\/strong><\/p>\n\n\n\n

The \u201cScaling Up Rewilding in Western Iberia\u201d project is financed by the Endangered Landscapes Programme, which is managed by the Cambridge Conservation Initiative and funded by Arcadia, a charitable fund of Peter Baldwin and Lisbet Rausing. The project is being coordinated by Rewilding Europe, in partnership with Rewilding Portugal, the University of Aveiro, Associa\u00e7\u00e3o Transum\u00e2ncia e Natureza and Zoo Logical. Sponsored by Mossy Earth, the tagging of the griffon vultures was carried out by Associa\u00e7\u00e3o Transum\u00e2ncia e Natureza, together with members of the Rewilding Portugal team. As scientific collaborators, CIBIO-InBIO and Movetech provided the transmitters and are also supporting with data analysis and the dissemination of results.<\/p>\n\n\n\n
