Despite the good adaptation of the species to the new habitat, witnessed by the results of the intensive monitoring activity of the first years, the new-colony was estimated to be, in 2003, of only 43-51 specimens (30-33 in Val di San Valentino and 13-18 in Val Genova). The comparison with normal trend of growth of the species, according to which the number of ibexes should have been around 190-210 individuals, have led to the hypothesis of an evident numeric inadequacy of the colony, worring at the point of justifying a new phase of studying guided by the willing to discover the reasons of the nongrowth of ibexes’ colonies.

In 2005, the Adamello Brenta Natural Park has scheduled a monitoring phase, aimed at the obtainment of basic information about the distribution, consistency and moves of ibexes in the various areas of their habitat. To increase possibilities of contact with other herds, during spring 2005, also thanks to the support of Forest and Wildlife Service of the Autonomous Province of Trento, six ibexes (3 males in Val Genova, 2 females and 1 male in Val di San Valentino) were captured and equipped with radio collars.

Captures continued in 2006 with the application of four radio collars to other four specimens: four males captured in Val di San Valentino. The radiotelemetry monitoring, with the consequent attempt to arrive at the sighting, revealed itself as a fundamental instrument to better know the status of the ibex population in the Adamello – Presanella Mountain Range and to increase the number of contacts among the various herds.

The critic analysis of datas have led to the hypothesis of a total presence of more than 110 specimens in 2007. From 2008, the Park’s ibexes’ population have been monitored with naturalistic methods and, in 2013, based on the results obtained with monitoring activities, the number of ibexes present in the territory of the Park was estimated to be around 180-200 specimens.
Even if, in 2019, the species is no more object of specific projects, the Park’s attention to ibexes’ population in the territory of the protected area is still high, especially given the importance of this population in the distribution framework of this species on the Western and Central Alps.
