Other targeted or smaller-scale activities, also environment-related, are constantly carried out in Trenca. For instance, the building and placing of nest boxes for lesser kestrels (Falco naumanni) in the regional district of La Noguera, the clean up of different stretches of the Segre river with the participation of volunteers or the dispersion of thousands of starlings that roosted in the electrical power station of Magraners, all three actions done in 2012, in the province of Lleida. Some of these smaller actions are also in line with the tasks of the Wildlife Centre of Vallcalent.
The conservation of the Lesser Grey Shrike (Lanius minor) in Spain is another big project in which Trenca takes part. It is the responsability of our entity the field work tasks related to this programme: to locate the wild birds and territories, interventions at the wild nest, supplementary feeding, release of chicks, predators control, habitat improvement and surveillance. These in situ interventions, together with the captive breeding programme that is carried out at the Vallcalent Wildlife Centre and at the Zoo of Barcelona (ex situ interventions), are the core of the preservation plan for this species.
A big management and conservation project our Association takes part is the reintroduction of the Black Vulture (Aegypius monachus) in the Pyrenees. The aim is to help with the recovery of a species that was extinct in the recent past in the Pyrenees, to reduce the risk of genetic erosion of the Black Vulture in the west of the European continent, to help with the recovery of their former circum-Mediterranean range as well as to influence local population of the Pyrenees: knowledge of the species, awareness of the fact that the biodiversity is a heritage of all of us and its conservation and wealth also imply an economic benefit.
Another current big project of Trenca is the sustainable agri-environmental development project in Les Garrigues (Lleida), with the aim of carrying out an agricultural activity that has to be financially profitable, environmentally sustainable, and respectful of the cultural and landscape heritages of the territory. The project has still involved the creation and marketing of the extra virgin olive oil brand Salvatge (Wild), olive oil from the wildlife reserves.
A rel de l’observació de fins a tres exemplars de Tortuga mediterrània (Testudo h. hermanni) a la Vall de Bovera (comarca de les Garrigues, Lleida) procedents de la població reintroduïda al Parc Natural de la Serra del Montsant, l’Associació TRENCA va proposar al CRARC (Centre de Recuperació d’Amfibis i Rèptils de Catalunya) la possibilitat de consolidar aquesta incipient població. L’existència de finques de propietat de TRENCA així com d’altres amb acords de custòdia del territori, a més de la idoneïtat de l’hàbitat, va facilitar que s’engegués el Projecte de Reintroducció de la Tortuga Mediterrània a les Garrigues l’any 2016.
Along with the release of black vulture specimens, Trenca has made and manages 3 supplementary feeding points (SFP) to strengthen ties between the reintroduced black vultures and the releasing area. Besides the Black Vulture, other scavenger raptors are also using the SFPs: the Egyptian Vulture (Neophron percnopterus), the Bearded Vulture (Gypaetus barbatus), the Griffon Vulture (Gyps fulvus), the Black Kite (Milvus migrans) and the Red Kite (Milvus milvus). This initiative eases the lack of food that all these species –which are key to the ecological balance of ecosystem– are facing, and also reduces the impact of poison use.
With the increasing number of white storks and the interaction of this species with human beings (most of the nest are located in urban areas), a series of actions is carried out aimed to conserve this bird and at the same time to achieve a great cohabitation between people and white storks in urban areas. Since the year 2001, different tasks are carried out whitin the action and conservation plan for the White Stork in Catalonia. The Trenca’s help is focused on the actions on the nests (cleaning roofs of buildings, removing nests as well as building and placing new nests) and the chicks (rescuing chicks that would end up dying).
