A favourable area means that known conditions appear compatible, not that mushrooms are visible there. Mycelium may be absent, not fruiting, already finished or responding to a microclimate that regional data cannot capture.
A map does not observe every metre
Habitat and weather layers have a resolution, date and uncertainty. They may describe a forest well while missing recent felling, compacted ground, a dry edge or a small damp hollow. Real terrain is finer than the pixel.
Compatible habitat does not prove presence
A partner tree and plausible soil do not prove that the target mycelium occupies a site. Dispersal, forest history, disturbance and biological competition also shape distribution. Observation maps are further biased toward places people visit.
The visible window can be short
Animals, other collectors, wind, heat and fruiting body age change what is visible. An empty visit does not automatically disprove the habitat, but it should refine expectations and never justify leaving permitted routes.
FAQ
Frequently asked questions
Does an empty area mean the map is wrong?
Not necessarily. The map expresses potential. Data can be wrong, but timing, microclimate or the local absence of mycelium can also explain it.
Should I return the next day?
One day guarantees no change. Return only where access is permitted and when weather development, season and habitat make another observation worthwhile.
