The need for future wetland bird studies: scales of habitat use as input for ecological restoration and spatial water management.

The article illustrates the importance of future wetland bird studies in order to preserve threatened species in wetland areas. It discusses four levels of spatial and temporal habitat use by wetland birds and the significance of the interaction between scale levels and ecological process on the level of migration flyaways on both regional and international level of landscapes. It suggests the need for spatial planners to incorporate habitat use of birds by scale levels into their efforts of realising ecological restoration, rehabilitation of wetlands and sustainable water management.
