Urban green space (i.e. urban biodiversity and green infrastructure) provides multiple ecosystem services in areas of high population density. In these areas, resistance and resilience of green space to e.g. climatic extremes are thus of prime importance for the maintenance of ecosystem services. However, urban green space design and management is still mainly structured for traditional aesthetic and recreational purposes. Opportunities for programming for resistance and resilience are overlooked. Instead, it is assumed that design and management interventions can restore green space functionality if catastrophic loss occurs. Unfortunately, this lack of understanding of the importance of minimizing the necessity for such interventions can be costly. It can lead to significant resource shortages in the management of urban green space, with the consequence that this space cannot be used to its full potential. The overall aim of our project is to develop guidelines for the management of urban green spaces in Ireland which promote resilience. These guidelines will be based on a systems approach, where management decisions are conceptualized as interventions in a socio-ecological system. In order to prioritize action it will be recommended to develop an understanding of system dynamics both in terms of natural processes such as dispersal of organisms and water flow through the landscape, as well as in terms of the human usage and movement in green spaces. This basic understanding can then be used for the design and selection of management scenarios which can enhance resistance and resilience of urban green space. In our presentation we are going to look more in depth at the functionality of urban parks in Dublin City and how their functioning is interrelated with connectivity to the UNESCO Biosphere Reserve of North Bull Island. This is the only UNESCO Biosphere in the world which is entirely situated within a capital city and the Island was formed entirely as a consequence of human intervention through 19th Century construction of sea walls for navigation purposes. We will explore how urban parks can be managed at an ecosystem level to support core conservation zones of outstanding international ecological significance. We will also provide examples of how the community involvement in management of urban parks is changing and influencing traditional parks management to incorporate measures for conservation and resilience of ecosystem services.
