The article "State of knowledge on non-native plants in protected natural areas of Argentina and Chile" analyzes biological invasions and their impact on biodiversity. It highlights the importance of having updated information on native and non-native species in protected areas. Studies on the distribution of these species in national parks and nature reserves in Argentina and Chile are mentioned. The need to implement management strategies to control invasive species and preserve the functionality of protected areas is also emphasized. It is recommended to consult the full article for more details. [Extracted from the article]

In order to guarantee the protection, conservation, restoration and use of natural resources (water, soil, forest and biodiversity) of an anthropised sector belonging to a protected natural area of the State of Mexico, a management proposal based on a detailed field survey, which allowed to diagnose the main environmental problems is made. After extensive community work, awareness and discussion of best wishes for caring and conservation of the property, a management plan agreed with the community was established, where strategies and action strategies are established according to priority levels. Communal management is maintained as an inseparable element of the process. The project is an example of conjugating the professional area and the citizen involvement in environmental matters in order to preserve the environment. [ABSTRACT FROM AUTHOR]

In Mexico and in other parts of Latin America, a large overlap can be observed between indigenous territories and regions of high biological value. In this paper, we ask if the same overlap can be observed in the state of Jalisco, in western Mexico. To answer this question, we start with a succinct analysis of the two main indigenous regions in rural Jalisco: the Huichol Sierra in the northern part of the state and the Sierra of Manantlán, in the southern part. Then, we extend our analysis to the state in its entirety in order to measure the overlap between indigenous territories that have been "desindianized" and regions of high biological value. This is done by comparing the municipalities that contain agrarian centers designated as "indigenous communities" and the municipalities that areas officially recognized for their ecological importance. A high correlation between these two variables is observed, leading to the question "why". A series of hypotheses is developed and these are contrasted with empirical evidence through a case study of the ejido of Ayotitlán, in the Sierra of Manantlán. Although different forms of environmental degradation can be observed in Ayotitlán, it continues to be one of the best conserved territories in the state of Jalisco, with high levels of biodiversity. This is due, not only to its isolation, but also to the way in which the indigenous inhabitants have interacted with the environment and because of their activism in defense of their territory and natural resources.

The establishment of a protected area installs new rules over the use and management of natural resources, modifying how people relate to their environment, as well as the way in which the space is comprehended and constructed. How does this process occur? How does the creation of protected natural areas transform or disrupt territories? The hypothesis that we present in this work is that the creation of protected areas, when it does not include local consensus and negotiation processes, may result in dynamics of deterritorialization, creating what Marc Augé (1993) referred to as non-places. From this perspective, we explain the meagre results both social and environmental of some natural protected areas in Mexico, and propose a vision of conservation focused in places, according to the anthropological connotation of the term.
