A very interesting publication has just come out about the reintroduction project of the Mohor gazelle (Nanger dama mhorr)!
This project has been a milestone in the conservation of this impressive Sahelo-Saharan species. Currently the populations are very rare and isolated, and is declared “critically endangered“.
Reintroductions continue to be an important conservation action for endangered species. Until this, all reintroduction projects for Mhorr gazelle (Nanger dama mhorr) had remained at the stage where the animals live in fenced protected areas of different sizes. This study describes the first experience of reintroduction of a group of 24 Mhorr gazelle into the wild in the Safia Reserve. The reintroduction was carried out in two phases: in the first one, the entire group was released; then, after an unexpected dogs attack event, part of them were kept safe until this problem was solved. Seven of the gazelles were monitored with telemetry collars, providing previously unavailable data on time allocation, daily rhythm of activity and social organization for the species in the wild. In addition, post-release movements revealed three patterns: during the first few days after release, small daily movements (average 2.78 km) close to the fence, followed by long-distance exploratory movements (up to 50 km) until establish territories; and finally, daily movements between established territories (average 8.39 km). Exceptional long distances (>50 km/day) were traveled after a poaching event. The study has also revealed the ability of the species to select and settle territories in favorable areas, after being kept for generations under captive or semi-captive conditions. However, their inability to recognize predators was demonstrated in an unexpected attack by dogs, resulting in the death of seven released gazelles. This mortality following the dog attack was favored, in part, because the released gazelle remained close to the fence, and therefore suggests that the release procedure should be revised, especially when there are predators in the release site. This study has confirmed that dogs as predators and poaching continue to be the main threat to reintroduction projects.
Very good experience and knowledge, that we will improve to the success of future reintroduction projects.

International Day of Biodiversity under the motto: “Our Biodiversity, Our Food, our Health”. The CBD-Habitat Foundation together with IBAP and Orango Parque Hotel commemorate this day with the inauguration of “The Bijagos Exhibition” at the Guinean Cultural Center of Franco Bissau. The presentation of the exhibition was it made by the Secretary of State for the Environment and the Director of IBAP of Guinea Bissau.
This year’s celebrations of the International Day for Biological Diversity,on 22 May 2019, (Convention on Biological Diversity,CBD) focus on biodiversity as the foundation for our food and health and a key catalyst to transforming food systems and improving human health. The theme aims to leverage knowledge and spread awareness of the dependency of our food systems, nutrition, and health on biodiversity and healthy ecosystems.
The theme also celebrates the diversity provided by our natural systems for human existence and well-being on Earth, while contributing to other Sustainable Development Goals, including climate change mitigation and adaptation, ecosystems restoration, cleaner water and zero hunger, among others. In the last 100 years, more than 90 percent of crop varieties have disappeared from farmers’ fields. Half of the breeds of many domestic animals have been lost, and all of the world’s 17 main fishing grounds are now being fished at or above their sustainable limits. Locally-varied food production systems are under threat, including related indigenous, traditional and local knowledge.
With this decline, agrobiodiversity is disappearing, and also essential knowledge of traditional local foods. The loss of diverse diets is directly linked to diseases or health risk factors. Decisions from the 14th meeting of the Conference of the Parties to the UN Convention on Biological Diversity, along with reports on biodiversity and health, provide recommendations. In addition, the EAT-Lancet Commission recently published findings on the healthnutrition-food systems-biodiversity nexus, that describe what constitutes a healthy diet from a sustainable food systems perspective, and which actions can support and speed up food systems transformation, in benefit of biodiversity.
The links between biodiversity, ecosystems, and the provision of benefits to human health are deeply entrenched in the Strategic Plan for Biodiversity 2011-2020. They are central to our common agenda for sustainable development. This focus on the nexus of biodiversity, food systems and health provides an opportunity to generate discussions on ways to support the post-2020 process for a global biodiversity framework and to help “bend the curve of biodiversity loss by 2030”. In this regard, the UN Convention on Biological Diversity together with a range of partners, including the WHO, FAO, UNICEF, UNESCO, as well as other entities like EAT Foundation and the Food and Land Use Coalition (FOLU) are working together to identify transformative actions, through global food systems, to advance progress in support of biodiversity, climate, health and other related Sustainable Development Goals.
Sustainable Development Goals:
The Vulture Conservation Foundation is committed to conservation, restoration and protection of vultures as umbrella species for their natural habitats throughout Europe. The VCF is an international NGO committed to the conservation of the European vulture species: Bearded Vultures (Gypaetus barbatus), Griffon vultures (Gyps fulvus), Cinereous vultures (Aegypius monachus) and Egyptian vultures (Neophron percnopterus). VCF has extensive experience in breeding, reintroduction and protection of vultures in their natural habitat.
All European vulture species have a highly vulnerable status, and their distribution ranges have been severely restricted in the last century. Threats such as illegal poisoning, lack of food availability and collisions at wind farms and powerlines are putting the incipient recovery of some populations at risk. The isolation of many of the breeding populations and low productivity rate of the species make it difficult to ensure the survival of these species in the long term. Vultures require large natural areas of good quality habitat, which is increasingly difficult to find in the humanized European continent. Because of their unique role in the ecosystem, vultures are ‘keystone species’ in European mountain landscapes. They cut the vector of infectious disease transmission, act as natural carcass recyclers and are of great socioeconomic value to local communities. Protecting vultures therefore means protection of the entire European mountain ecosystems.
Farming for vultures: the results from the LIFE+ Feeding Scavengers project
Changes in farming practices was one of the factors that contributed to the decline of populations of vultures across Europe, the LIFE+ Feeding Scavengers in Spain has been working over the last four years to work with livestock owners to develop the management techniques for vultures and other birds of prey.
An emerging threat to Cinereous Vultures in Spain
The Cinereous Vulture population in Spain now accounts for over 96 percent of the total European population and thanks to the dedicated actions of projects over the last 40 years increasing from just 200 pairs in the 1970s to well over 2,500 pairs today. However, with the increase in the population the species the threat of lack of food availability is emerging as an important factor affecting the population. The combination of measures to control the spread of BSE such as laws requiring livestock owners to safely dispose of animal remains, the decline of the practice of extensive livestock grazing and stricter health controls from farms and slaughterhouses have resulted in a steep decrease in the food available for Cinereous Vultures and other birds of prey. The LIFE+ Feeding Scavengers project led by CBD-Habitat Foundation, Ministry of Development and Environment of the Junta de Castilla and León, and the Natural Heritage Foundation of Castilla y León, which came to an end in December 2018 aimed to deal with this situation in central Spain.
Collaborating with livestock owners
Key to the project was working with farmers across Castilla y León, covering the whole of the range of Cinereous Vultures in the region, to change practices to increase the food available to the species. In total the project have been collaborating with 550 farms and 30 livestock associations and cooperatives which cover around 500,000 ha.
Following the passing of Decree 17/2013 by the Castilla y León regional government, which authorises the use of animal remains from extensive livestock for the feeding of scavenger species.The project worked with farmers to develop new management techniques which included extensive consultations to understand the implications of the new law such as recording information about the animal and the location of the animal remains that would not cause risks to people or animals for example near water sources, homes or powerlines.
Farming for vultures
By the end of the project a total of 355 farms who practice extensive grazing have collaborated with the project and have been authorised by the regional governments to manage their herds in a more vulture friendly practice. This accounts for 85,793 sheep, 5,711 goats, 2,257 cows, 3,873 pigs and 442 horses which the projects has found is associated with it an annual mortality of around 376,000 kg of biomass. By being authorised to leave the remains of this livestock in the natural environment this biomass becomes available to vultures and other birds of prey such as Iberian Imperial Eagle, Red and Black Kites and Golden Eagle. This work also highlighted the economic benefits of this practice of freeing up significant amount of time for livestock owners and reducing carbon emissions by 30 tons / year of CO2 by eliminating the need for incineration of animal remains. Increasing the food available in the natural environment is helping reduce the competition between vultures and the other birds of prey in the region, which will help the recovery of the Cinereous Vulture in the region and improve conditions for the Egyptian and Griffon Vultures.
The LIFE+ Feeding Scavengers project is a great example of collaboration between a non-governmental organisation, governmental agencies and livestock owners to change practices that has positive impacts on vultures.
