On the basis of analysing the results of European research defining the directions of increasing the efficiency of actions and minimising the barriers for development of urban greenery and previous own research, a programme of further research conducted by the Institute of Spatial Planning and Housing was developed. The purpose of this research is to implement a new approach of urban policy, taking account of the “green infrastructure” as the Europe’s natural capital. The basis for the development of this programme were ongoing studies of the Institute of Spatial Planning and Housing carried out, among others, on a highly urbanised area of Praga-Północ (district of Warsaw), which was covered by the monitoring of condition and value of the vegetation, especially of street trees, the assessment of possibilities and barriers for further development and the evaluation of the range of ecosystem services generated by urban trees. The importance of this information was stressed to improve the management of the resources of green infrastructure in the cities and carry out environmental education of the population. The results of these studies will be used to produce a model of managing the resources of urban trees in the context of sustainable development, with particular regard to the priorities of urban environmental policy of the EU and the directions of increasing the efficiency of ecosystem services in the cities, with the broad participation of the local population.
