GIS-based assessment of ecosystem service demand concerning green infrastructure line-side vegetation

A module-based Green Infrastructure (GI) and Ecosystem Service (ES) approach, adapted to the specific requirements and conditions for railway line-side vegetation management, is presented in this paper. The multi-functionality of line-side vegetation is addressed by an integration of the GI and ES concepts. The use of widely available geo-data enables its applicability, both in terms of large-scale and other infrastructure networks. In this way it can serve as a feature for emphasizing the creation of a productive, attractive and cost effective landscape resource. A methodological approach for the Ecosystem Service Demand Assessment (ESDA) of GI line-side elements was developed and applied at a study site. An ESDA was performed concerning “Structural landscape diversity” and “Water and climate regulation”. The results represent the composition of landscape types, the demand for structural landscape features, the distribution of GI line-side elements and hotspots of land consumption. Additionally, potential capacity of GI line-side vegetation to provide ecosystem services was addressed. Maps created provide basic information for the railway operator to consider ecosystem service demand in construction and maintenance works. In this way, the presented GIS approach can support decision-making-sovereignty in implementing holistic line-side vegetation management strategies. The use of high resolution geo-data proved to provide a good basis for the accurate mapping of GI line-side elements. The study has confirmed that high resolution geo-data and GIS technologies have great potentials regarding spatial data provision and as analytical frameworks for line-side vegetation management.
