The research was carried out in the Andean matorral affected by forest fires in the "Francisco Vivar Castro" at the University Park. The objective was to characterize the current composition and diversity of the Andean matorral affected by forest fires and the state of natural regeneration. To know the floristic composition, five permanent plots of 20 m x 20 m were installed where all the shrubs greater than 1.50 m in height and individuals with diameters greater than five centimeters at breast height were measured. Natural regeneration was evaluated by category in nested plots: five subplots of 1 m x 1 m for seedlings, five subplots of 5 m x 5 m for brinzales and latizales in the 20 x 20 m plots. All individuals were tagged with a unique code for later monitoring. The composition and diversity of the Andean matorral affected by forest fires was 769 individuals in twenty-seven species, twenty-four genders and sixteen families, with a medium diversity (1.46), and the presence of four endemic species. The Andean matorral structure is dominated by species such as Lepechinia mutica (29.35%), Dendrophorbium scytophyllum (22.47%) and Pappobolus acuminatus (8.15%), which represent 84% of the total individuals, and trees such as Alnus acuminata and Clethra fimbriata. The natural regeneration of the Andean matorral was represented by 1 008 individuals belonging to thirty-one species, twenty families and thirty genders. The seedling category registered a total of sixty-six individuals, brinzales 866 individuals and latizales with seventy-six individuals. Natural regeneration is dominated by Dendrophorbium scytophyllum and Clethra fimbriata in the three categories. The Andean matorral is in a process of natural succession with adequate natural regeneration. Keywords: fire, regeneration, restoration, shrubland, succession. |
