USE OF ARTIFICIAL PERCHES IN THE RESTORATION OF THE SEED BANK IN AN AREA OF RIPARIAN FOREST
Keywords:Environmental restoration, Frugivorous birds, Ornithocory
Riparian forests are considered permanent preservation areas and include all types of vegetation that are linked to the banks of rivers with great importance for the maintenance of water resources. The natural regeneration of a degraded area depends on thearrival of seeds to this place, which can be transported by various means, including birds. The objective of the present study was to evaluate the role of artificial perches as attractive to birds and their effect on the restoration of the seed bank of anarea of degraded riparian forest, located in the city of Doutor Camargo / Paraná –Brazil. 16 artificial perches were installed with collectors for bird droppings and 16 collectors without the influence of perches (control). The data were obtained betweenJune and September 2010. 3,673 seeds were sampled, of which 2,945 were in the middle of bird droppings. Significant differences were found in the amount of seeds sampled in collectors without perches and with artificial perches, demonstrating the importance of perches as an auxiliary tool in the process of restoring degraded areas.
