In 1999, at the initiative of the Adamello Brenta Park, in agreement with the Autonomous Province of Trento and the National Institute for Wildlife, a project funded by the European Community was launched to revive the fortunes of the last small group of bears in the Brenta, known as Life Ursus. The ten bears, released between 1999 and 2002, helped to save the brown bear (Ursus arctos) population. Among them, on 18 May 2000, Daniza joined the group — she was killed on 11 September 2014 by a fatal dose of sedative.

To ensure the health of all the individuals, the project was structured in various phases, from monitoring specimens both via radio collar and through genetic analysis, to monitoring the feeding habits of the plantigrades. In addition, to guide conservation operations, from 2005 onwards a survey was launched aimed at identifying the greatest possible number of winter dens.

The bear and humans. To deepen understanding of the mammal's ethology, numerous initiatives were put in place, both to gauge the extent of anthropogenic disturbance — that is, the problems that can arise between bear habitat and human activity — and to better understand the behaviours bears adopt when they encounter humans accidentally. In this context, communication activities aimed at the population in the area affected by the reintroduction were set in motion.

The project, which concluded at the end of 2004, delivered results: the group of bears living today in the Adamello Brenta area was, until a few days ago, estimated at around 50 individuals. Today there are 49.
