Table 2. Caveats to consider when carrying out or interpreting results from urban tree canopy cover distributional equity studies.

Reproduced with modifications from Schwarz et al. (2015), with permission from K. Schwarz.

1	Variables not examined might be better predictors of urban tree canopy cover or ecosystem services.
2	Examining patterns between socioeconomics and environmental amenities does not capture intent; it is equally important to understand the processes driving inequitable distributions.
3	Vegetational structure and social structure may be mismatched. Trees can take a long time to mature while social conditions in a city might change more rapidly.
4	Tree canopy cover is treated as homogenous across the unit of analysis however this is unlikely to be the case.
5	Trees are not always an environmental amenity.
