The Bearded Vulture (Gypaetus Barbatus) is an endangered species in Eu-
rope that feeds almost exclusively on bone remains provided by wild and domestic ungu-
lates. In [1], we presented a P system in order to study the evolution of these species in
the Pyrenees (NE Spain). Here, we present a new model that overcomes some limitations
of the previous work incorporating other scavenger species (predatory) and additional
prey species that provide food for the scavenger intraguild and interact with the Bearded
Vulture in the ecosystem. After the validation, the new model can be a useful tool for
the study of the evolution and management of the ecosystem. P systems provide a high
level computational modelling framework which integrates the structural and dynamical
aspects of ecosystems in a compressive and relevant way. The inherent stochasticity and
uncertainty in ecosystems is captured by using probabilistic strategies.
