Abstract(s)
The urban woodlands are an important refugee to birds that canât find the essential conditions to their survival. The great diversity of these sites and the different existing habitats make them an hot-spot for conservation in urban spaces.
So, itâs important to know which factors influence the species distribution and how the changes in land use can affect them. This study intends to create a methodology that allows predicting the impact in avifauna of different evolutionsâ scenarios.
The birdâs survey was done with a grid, all over the Tapada da Ajuda with analysis of some environmental and land use characteristics. The observed results allow the identification of same habitatsâ choice characteristics and the formation clusters of habitats associated with a group of bird. From these groups, it was possible to create a methodology that permitted to predict the number of grids with favorable characteristics for each species.
It was conclude that two management guidelines could be followed, depending on the objectives: increase forestry to preserve the maxim of diversity or a few of species that have their populationâs maxim in Tapada; or increase brush-trees crops to preserve a few species that in Lisbon, only exists in Tapada da Ajuda.
