Reintroduction of the Black Vulture in the Pyrenees:  NESTS  IN  2011

Season 2011 was characterized by the consolidation of a small reproductive nucleous of Black Vulture (5 formed pairs; 4 with clutches) as well as a number of immature and subadult individuals progressively settled in the territory.
Nevertheless, there were no fledglings in the season 2011. This situation can be considered normal in a young colony that has just formed with mostly inexperienced pairs.

Les Garrigues (The Garrigues)

Sustainable agri-environmental development in Les Garrigues (Lleida)

March/2012

Sustainable agri-environmental development in Les Garrigues (Lleida)

The Trenca’s project involves the development of agricultural activities in the garrigue mediterranean ecosystem, in a respectful way regarding natural, agrarian, landscape and cultural heritages.
Actions to help fauna and flora have been made; dry stone walls, cabins and cisterns have been rebuilt and hundred-year-old olive groves that were abandoned have been recovered.  Now, we grow those olive trees using organic agriculture. The product is commercialized under the brand Salvatge. Oli de les reserves de fauna, (Wild. Olive oil from the wildlife reserves) in order to prove that we can make a profitable economic activity with an organic oil no only because of its value with regard to human health, but also because of another added value: the conservation and improvement of the biodiversity and the recovery of the cultural heritage.
This project received the recognition of the Social Entrepreneurship Programme from the Benevolent Work of “la Caixa” in the year 2012.

Other environmental actions

Cleaning of buildings where Stork nests are located

For more than 10 years now, Trenca, together with the Wildlife Rehabilitation Centre of Vallcalent,  has been carrying out an action and conservation plan for the White Stork (Ciconia ciconia)  in Catalonia. Among other things, actions include cleaning and maintenance of buildings and infrastructures where the colonies are located, wintering census of the species or tracking of the productivity of chicks.

Cleaning work day of the Segre river with volunteers

On Sunday, December 22, 2012, the Trenca Association’s project: ‘Environmental recovery of different stretches of the Segre river  through removing waste materials with volunteers’ was completed. It had been selected for the call “We want to help our natural areas” organized by the chain of supermarkets Plusfresc in collaboration with IPCENA Association.

The aim of the proposal was to get a social action to clean and recover different points of the Segre river where illegal dumpings have been detected or a large number of waste materials were found on. We were 87 people in all. Through this action we also aim to raise the awareness of the civil society on the problems related to illegal waste dumpings on such a sensitive area as a river.
