The main objective of this work is to describe the structure and conservation status of the forest of Prosopis flexuosa and Prosopis chilensis around Huaco and in the adjacent basin of the Bermejo River (department of Jáchal, San Juan). Currently, this genus has changed its name to Neltuma. To this end, baseline information for the conservation and sustainable management of these little-studied native forests was generated from an inventory that took into account dasonomic parameters such as conservation status and tree form. This information is linked to a forest typology based on satellite image classifications. The results are expressed in a proposed classification of four native forest types for this locality and its surroundings. This classification includes, in addition to the characteristics of the area covered by native forest, the identification of the different uses and disturbances that have impacted it in recent decades. Finally, different management and land-use planning proposals for these forests in northern San Juan are preliminarily discussed. [ABSTRACT FROM AUTHOR]

The architecture of plants responds to endogenous processes and to the influence of environmental factors. The allometric study of architecture has been a challenge for biology. We define a new finite (Hausdorff) dimension of plants, that considers both the aerial part and the roots, and compute examples. This new finite dimension was introduced recently and, in contrast to the classical Hausdorff dimension, is not zero on finite sets. We propose the finite dimension, as a function of time, as a "signature" of the plant or root. Our first results suggest that the signature is specific to each plant species and its growth period, and constitutes an objective metric that allows to study its ontogenesis in detail.
