A highly forested tree city still undersupplied specialist flower visitors
WHAT THE EVIDENCE SAYS
A survey of 1,934 trees across 200 blocks found 72% of individual trees were non-native. Flowers and modeled resource connectivity favored small-insect and bee guilds, while some specialist visitors had fewer or more fragmented resources.
WHY IT MATTERS / OUR READ
Urban canopy coverage should be evaluated against phenology and the specific animals it supports, not simply total shade or tree counts.
CAVEATS / UNCERTAINTY
Floral morphology and spatial proxies do not directly establish pollen transfer or trends in pollinator population viability.

Campo Grande has year-round street-tree flowering, but its resource network favors generalized insect visitors.
