Summary statistics of weighted residential vegetated land cover (%) variability by land cover weighing scheme.

Vegetated land cover weighting scheme Min 25th percentile Median 75th percentile Max Interquartile range
1: Average within 50 m radius 6.0 44.7 59.9 70.6 99.8 25.9
2: Exponential decay, distribution with λ = 0.02 10.6 50.5 64.1 72.3 97.4 21.8
3: Exponential decay, distribution with λ = 0.01 16.4 53.6 63.2 74.6 94.6 21.0
4: Exponential decay, distribution with λ = 0.005 20.9 53.0 61.1 71.4 86.1 18.3
5: Exponential decay, distribution with λ = 0.0025* 27.1 59.3 67.7 78.0 94.0 18.7
6: Equal weights for 50 m annuli within 500 m 31.7 61.1 68.7 78.5 94.3 17.4
7: Average within 500 m radius 36.9 63.8 72.8 78.8 95.2 15.0

Weights were rescaled so that they add up to 1 within the ten 50-m annuli.
