Aim Fire protection gradually changes the density of woody plants in numerous savanas around the world. In this study changes of structure in two tropical savana areas with contrasting history of fire protection in the central Brazilian Cerrados is documented. Location Vegetation was sampled with line intercept transects i two adjacent sites in Brasília, Federal District. These transects were located within a nature locate within a nature reserve protected from fire since 1972 and within na adjacent reserve area that burns avery 2 years. Methods Five savana physiognomies, from a low forest ('cerradão') to an open savana ('campo sujo'), were sampled in both sites. Results Fire protection increased the abundance of woody plants and favoured firesensitive species. With some exceptions, shrubs tended to be less affected by fire than trees. Species distribution was affected by complex interaction of fire and physiognomy.Fire had the strongest effect on 'campo sujo' savana, and a les significant effect on the intermediate physiognomies. Main conclusions Protection permits the establishment of fire sensitive species. A long enough protection against fire could lead to the appearance of more wooded physiognomies in the Cerrado. |
