Where the mushrooms are, today.

What the forecast actually does

1. 01

   Looks at the forest

   Tree species, canopy cover, elevation and which way the slope faces — point by point, at twenty-eight metres.

2. 02

   Looks at the weather

   Rain accumulated over thirty, sixty and ninety days, last week's temperature, and soil moisture measured from orbit.

   Answers per species

   A saffron milk cap and a porcini do not want the same tree or the same water. There is a map for each, not one map of "mushrooms".
