1. Biodiversity and green infrastructure in urban landscapes
Sammanfattning : In this thesis, I evaluate the extent to which biodiversity is affected, and taken into consideration by, urban planning. Based on landscape ecology, I apply an interdisciplinary approach. LÄS MER
2. Management of urban woodlands - effects on bird communities and recreational values
Sammanfattning : The ongoing urbanisation increases the pressure on urban nature. Urban woodlands are receiving growing attention as they provide valuable ecosystem services to urban citizens, mainly by providing areas for recreation but also through improving air quality and reducing noise.
