Urbanisation alters habitats by removing
and replacing them with 
. This has significant and varied effects on #birds – more and less may both lead to declines in 
species richness.
But which is more important for maintaining #urbanbiodiversity?

To test this, I selected
suburbs in greater Melb, stratified to represent two gradients – density (or % cover of ) and canopy cover.
In each suburb, I established
sites and conducted 
rounds of point count surveys for from Sep 18 – Dec 19.

Overall, I recorded
species. The richness per suburb ranged from 
- 
species.
My prelim results show that as a suburb becomes more developed, we see a significant decline in the no. of species recorded.
More cover = less species

In contrast, suburbs with a greater extent of canopy had a higher number of species present.
More canopy cover = more species! 
Of these two factors, density appears to be a better predictor of species richness (more modelling to come!).

In summary, increased density leads to a decline in species richness.
However, we may be able to maintain by retaining canopy cover!
These findings will be increasingly important for #urbanconservation as development progresses across Melb
