Jabalí ( Sus scrofa ) introduced mammals are established in 26 of the 33 protected areas.
is known occurrence of species of introduced mammals in nature reserves of southern South America. For example, in Argentina 19 of 31 introduced species of mammals are currently considered as pests that occur in natural or semi-natural. These species can be agents of change in the ecosystem and could threaten native biodiversity. This problem is poorly understood and there are few detailed studies of the distribution and impact of invasive species of mammals. In this study, Murphy and colleagues provide a detailed description of the distribution of invasive mammal species within the protected areas system of Argentina (now 33 protected areas and about 3.5 million ha.). The authors conducted a literature review and studies and information from the administrative offices of protected areas, interviews and analysis of collections of mammals. The results indicate that 16 invasive species are established in 26 of the 33 protected areas. The most widespread species are the European hare (Lepus europaeus ) and wild boar (Sus scrofa ). The authors found differences in the origin and use of species in different geographic locations. For example, the greatest number of species was found in Patagonia (both forests and steppes). In these southern areas, the species were introduced with the purpose of hunting or fur with important benefits for local economic activity. In northern areas of invasive species are more closely related to farming activities. This study is an important contribution to decision making in the management strategies of these species.
