But, these green spaces also serve as habitats for plant and animal species, facilitate soil water retention and carbon sequestration. One of such green spaces, is the Byoasen located in the Nørrebro suburb of Copenhagen, Denmark. A biodiversity survey was conducted aimed at assessing species composition, richness and biological heterogeneity. The species richness (flora and fauna) data were collected and weighted against natural factors e.g. arbor cover and anthropogenic factors e.g. human activity. The results suggested that biodiversity richness increased with increased arbor cover and within areas with little human access.
