A Melbourne study assessing bat, bird, and insect presence in urban habitats found that increasing volume of understory vegetation and percentage of native vegetation had positive effects on populations. A 30%-120% higher occupancy by bats, native birds, beetles, and bugs was observed with an increase in understory volume from 10% to 30%. The study also found 10%-140% higher occupancy across all native taxa with an increase in proportion of native vegetation from 10% to 30%.
