Cepello map methodology

What the Cepello mushroom map estimates

Cepello compares long lived habitat signals with more recent weather conditions. It highlights areas where those signals agree, rather than displaying reported finds, revealing precise spots or detecting mushrooms in real time.

01

Habitat and weather work on different timescales

Habitat layers describe forest cover, elevation, soil context and relevant tree communities. Weather layers describe a shorter window shaped by rain, temperature, wind and drying conditions. Combining them makes it possible to compare areas without treating recent rain as proof of mushroom growth.

Every map layer has a spatial resolution. A mapped area can still contain a dry edge, a damp hollow, compacted ground or recent forestry work that the broader dataset does not show. The result must be checked against the actual woodland.

02

Why suitable weather cannot replace suitable habitat

Many fungi depend on particular trees, substrates or stages of forest development. Cepello first asks whether an area offers a plausible ecological setting for the selected mushroom. It then considers whether recent conditions may support or suppress fruiting.

Keeping those questions separate prevents a rainy forest from being treated as universally promising. Weather can strengthen a window within compatible habitat, but it cannot create the fungus or a missing partner tree.

03

How to use the result before a woodland trip

A stronger signal is useful for comparing areas, elevations and forest types. It is not a probability of finding a basketful of mushrooms. Plan more than one option and check access, protected areas and local foraging rules before leaving.

On arrival, inspect the real tree cover, litter, soil moisture and recent disturbance. An empty visit does not necessarily mean the data are wrong, just as one successful find does not prove that every similar area will produce mushrooms.
