Is this hostile environment the perfect conditions for some natives to thrive. Some native species, like dalakit (Ficus concinna), hawili (Ficus septica), is-is (Ficus ulmifolia), biga (Alocasia macrorrhizos) and gabing uwak (Monochoria vaginalis) are just plain resilient and could grow in the most surprising places. So it is not impossible to establish natie species in the bustling metro.
