Fungal bioluminescence, fireflies, glowtrees, a few fireflies in clearings and caverns, a few fungal lights in caverns, bioluminescence is violet.
Coastal fog, visibility 40 feet.
Normal forest with clearings fairly numerous.
Noticeable wind, stray distant lightning, no rain, warm winds.
It's generally dry with caverns free and rivers slow trickles.
Wood more likely to snap if moss is around, 33% decreased tensile strength for this level, ground noticeably more prone to landslides.
If plants permit there is vine-thatching over smaller gashes, cavern entrances are half crusted over, crust slightly harder to remove, vine-thatchings slightly brittle.
Lightning causes forest fires, volcanic activity, forest fires need sapient intervention.
