This paper analyzes the potential of Grindelia chiloensis, a native species of arid environments, which was studied as a tool for mitigating erosion and desertification in degraded soils. The research was conducted in a sector of Parque Norte (Neuquén) with characteristics similar to those of areas affected by small-scale fires. Soil samples were collected, physicochemical parameters (pH, moisture, electrical conductivity, N, P, and K) were measured, and a germination test was performed under controlled conditions. The results show that the soil, despite its loss of vegetation cover, maintains…

Wildfires alter essential soil properties, affecting its structure, stability, and surface dynamics. These changes, linked to the sedimentary materials that compose the terrain, increase erosion and hinder vegetation recovery. The study was conducted in Parque Norte (Neuquén), on soil with characteristics similar to areas slightly affected by wildfires, with the objective of assessing its recovery capacity using Grindelia chiloensis as a bioindicator species adapted to arid environments. From a geological perspective, the research aims to understand how vegetation contributes to stabilizing su…
