At the end of the 1990s
a last group of native alpine brown bears survived in
Trentino. The few remaining bears were unable to reproduce.
In 1999 a project to reintroduce the brown bear was
initiated, co-ordinated by the Adamello-Brenta Nature
Park, with the financial support of the European Community.
During the period 1999-2002, 10 brown bears from the
Slovenia population were released in Trentino. These
have since started to reproduce. In autumn 2003 there
were at least three young bears present in the province.
Since 1999 the brown bear has also been sighted occasionally
in the eastern part of the province, following natural
range expansion from the Slovenian-Austrian bear population.
The increased number of bears and the broader distribution
of the species has made it necessary for the Autonomous
Province of Trento to update regulatory, procedural
and organisational measures with the aim of best responding
to new needs in terms of management. In 2002, the Government
of the Autonomous Province of Trento established operational
policy for the management of brown bears within the
province, adopted specific "Action Plans"
and identified the Forest and Wildlife Department as
the provincial body of reference. The reorganisation,
which has already taken place, may be followed by further
improvements or modifications, according to a process
conditioned and guided by future case studies, requirements
and experience. This report quantifies and gives a concise
description of the most important initiatives implemented
in the last few years with the aim of alleviating conflict
resulting from the presence of brown bears and human
activities. It also highlights some critical areas.

As the brown
bear population size in the Adamello Brenta Natural Park is very low, it was
proposed to release Slovenian individuals to the Park in order to increase the
size and to guarantee a sustainable population. Prior to the release, a
feasibility study for the project was mandated and the probability of success
evaluated. The authors here describe the aspects that are important for a
successful reinforcement of the population.

The range of the brown bear in
Italy is limited to the population of the central Apennines, and to a residual
population of three old individuals in the Adamello Brenta Natural Park
(central Alps). Some individuals are occasionally recorded on the eastern Alps,
arriving from Slovenia and Austria. A translocation project aimed at
re-establishing a viable population of at least 50 bears in the central Alps
was proposed by the Adamello Brenta Park administration, in cooperation with
the Province of Trento. A feasibility study was conducted 1998, and it
indicated that the translocation had good probabilities to be successful in the
medium to long term. A survey on the attitude of the local population towards
the brown bear has been done, and 80% of the residents had a positive opinion
towards it. The reintroduction, coordinated by Andrea Mustoni, started in 1999.
The goal is for the population to increase, through natural reproduction of the
relocated animals over the next 20 to 50 years, to a total of 50 animals in the
Central Alps.

On this poster, the authors present
the work and the steps that are necessary for the reintroduction of brown bears
to the Italian Alps. It takes about seven years to prepare local people to it
and seven days to catch the bears in Slovenia and release them in Italy.

The last remnant population
that occupied the Adamello-Brenta Alps was considered biologically extinct
since 1989 (only three, non-reproducing bears). Here we present an analysis of
the reintroduction process as the most suitable tool for brown bear recovery in
the Italian Alps, taking into account both the benefits of reinstating a viable
population and the risks that the coexistence between man and bear could cause.
The reintroduction process is dicussed aiming at an evaluation of its
contribution to the global future efforts for brown bear conservation in the
alpine region.
A GIS-based habitat suitability analysis was implemented to test for
good-quality bear habitat in a vast mountainous area around the Adamello-Brents
Natural Park (6500 km²) , the release site of bears. The Model was based on
presence/absence data, gathered over the last 20 years, and habitat parameters
in 25 ha cells in the core-area of the remnant bear population (645 km² study
area). Other parameters of human disturbance and livestock densities were
considered at the scale of the municipality. Bears positively selected
deciduous forest but seemed to avoid areas with intensive pasture activity,
mainly of horses and sheep, despite the latter being a potential prey. Habitats
containing large amounts of bare rock, farmland and urbanised areas were
avoided. There were no significant differences between municipalities with and
without bears in human population density and intensity of tourism importance
of a wide-scale and detailed analysis of human attitude towards the project and
of education strategies to increase acceptance by local people are discussed.

In this paper, the author
first describes the population size and distribution
of the brown bear, the lynx and ungulates in the region
Friuli-Venezia Giulia (Italy). He then presents the
different natural parks and protected areas in the region.
He finally analyses (based on demographical, environmental
and sociological aspects) the different ways (naturally
or artificially) of re-enforcing or re-introducing the
great predators to the different parks and areas.

We monitored spacing behavior and settlement of
reintroduced brown bears in Adamello-Brenta Natural Park, North-Italy, using
radio-tracking. Habitat use, dispersion and survival were studied to evaluate
the success of reintroduction and possible conflicts with man. All three males
and five of seven females settled in the study area. Most bears roamed widely
the first months after release, exploring the new habitat. Patterns of home
range overlap between seasons and years revealed that home range use stabilized
the year after first hibernation. Home ranges were larger in the mating season
(May-July) than in spring or autumn. Home ranges varied between 34 and 1813 km²
the year after release, but core-areas, where feeding activity was
concentrated, were much smaller. Some bears had exclusive core-areas in summer
and autumn, but most showed considerable core-area overlap with animals of the
same and/or the opposite sex. Bears selected deciduous forests, mixed and
conifer forests were used according to availability, and areas with
anthropogenic disturbance were avoided. Most bears settled and some reproduced
successfully at the release site, causing high initial population growth,
suggesting that reintroduction can help to re-establish a brown bear population
in the Italian Alps. |

In
this document, the author comments on the planned introduction of Slovenian
bears to
the Trentino, where an autochthonous population is still present. He argues on
different levels against
the introduction: genetic differences between populations, different behaviour,
nature protection
and political aspects. He nevertheless discusses alternatives for the
introduction, i.e. taking measures for a natural resettlement of the Trentino-population.
