This project sits within a context of green infrastructure (GI). Sydney’s rail corridors are conventionally thought of as grey infrastructure but this appears to be a misconception given the frequent patches of shrubs and trees of varying size in many parts of the rail network. When viewed holistically and particularly when the potential for further planting is considered, rail corridors might be viewed as one of the sources for implementing a number of metro-wide environmental strategies. A premier environmental issue is carbon sequestration and storage (CS&S), a key focus of this pilot study. However, the GI of rail corridors brings a number of co-benefits – corridor cooling, air pollution mitigation, greater stormwater absorption and biodiversity enhancement. The pilot study examined all of these accompanying benefits and has identified a potential for intensifying planting which will magnify the ecosystem services accordingly.
