Phellinus pini is widely distributed in the Northern Hemisphere, causes the red ring rot and is the most importan! agent that affects softwood trees. In recent years the death of many Pinus greggi examples has been detected in Santiago Municipalitiy, Nuevo Leon State, which has been linked to it, with the resulting tree mass deterioration of the Monterrey Heights National Park. Thus, and due to what forests are worth in the State, the following objectives were proposed for this study: lo determine the impact of Phellinus pini, its association with some forestry variables and the pathological rotation age. Orcular sampling lots were placed in various locations; rottenness was assessed through samples token by a Pressler boarer, and its eventual laboratory cultivation in Petri boxes. Forestry variables were token from all the sampled trees to determine the factors that favor the incidence of this pathogen and, ffnally, the pathological rotation age. Age was the highest correlation variable, which was confirmad with the eldest examples, over which the most severe damages were observed. lncidence and severity were 11.66 and 123%, respectively; the pathological rotation age was 50 years.
