WHAT THE EVIDENCE SAYS
A Nature Reviews Earth & Environment commentary describes camera-based understory monitoring and an example integrating camera and drone information that identified asynchronous seasonal patterns across forest height strata. It proposes broader use to study trophic timing and climate-related shifts.
WHY IT MATTERS / OUR READ
Camera networks installed for mammals may also record vegetation change invisible to canopy-level remote sensing, potentially extending monitoring value at low marginal field cost.
CAVEATS / UNCERTAINTY
This is a methods perspective, not a newly validated global phenology dataset or proof that all camera placements permit unbiased time-series measurement.
