Read More: A Green Apartheid

There has often been a disparity in tree cover in poorer neighbourhoods and we know from a 2016 UCD study we know that this applies to Dublin too. While complete data are not available across all Irish towns and cities, there is growing evidence that a ‘green apartheid’ exists across most of our urban environments. Neighbourhoods with mature tree canopies enjoy cleaner air, lower noise and better mental and physical health.

One finding from a comprehensive UCD study on Dublin’s tree canopy is that while Fingal County Council recorded 9.8% canopy cover across its constituency, the figure for Dún Laoghaire-Rathdown County Council was 16.4% indicating that a greater number of trees and greenery are planted in areas populated by larger, more expensive homes beyond the city centre. It is striking that residents of Ballsbridge, Dublin 4, are up to 20 times more likely to have a tree on their street than those living in Dublin’s North Inner City.

More data are needed to determine if this is a common trend across all urban centres nationally, but an increasing number of international studies on the equitable access to nature present similar findings; for e.g. a nationwide US study led by American Forests, a conservation non-profit, found that “wealthiest neighbourhoods have 65% more tree canopy cover than the highest poverty neighbourhoods”. Importantly, another recent Australian study found that urban green spaces with open grass rather than a mature tree canopy do not deliver comparable health benefits for residents reinforcing the need for many and varied plant and tree species within our public spaces through careful tree canopy management.

Though there are many novel greening projects being initiated across the country there is currently no concerted effort to address this imbalance or ‘green apartheid’ within central government. This must change urgently if we are to protect all of our citizens from increasingly extreme weather events while improving overall quality of life. Tree planting must be focused in the neighbourhoods that need it most. All suburbs should be leafy suburbs.
