摘要
This study examines how fragmentation through changes in patch size and increasing distances between forest patches affects bird species richness. Numbers of bird species were higher in large forest patches and decrease with decreasing patch size. Bird species richness also decreased with increased isolation of forest patches. Suitable trees should be planted in the gaps between the forests that will create wildlife corridors to maintain connectivity. Resume Cette etude examine comment la fragmentation causee par des changements de la taille des parcelles forestieres ou par une distance croissante entre ces parcelles affecte la richesse en especes d'oiseaux. Le nombre d'especes d'oiseaux etait plus eleve dans les grandes parcelles forestieres et diminuait en meme temps que la taille des parcelles. La richesse en especes diminuait aussi avec l'augmentation de l'isolement des parcelles. Il faudrait planter des arbres appropries dans les vides existant entre les forets pour creer des corridors pour la faune et preserver la connectivite.
