Fungal bioluminescence, fireflies, glowtrees, a few fireflies in clearings and caverns, caverns well lit with fungal lights, bioluminescence a royal blue.
Coastal fog, visibility 40 feet.
Clearings gone, moss on tree trunks and above the tree line and on more rocks than not, plants have occasional dry leaves, normal amount of plants.
Noticeable wind, stray distant lightning, no rain, room temperature 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 reasonably sturdy (may be more prone to landslides).
If plants permit there is vine-thatching over smaller gashes, crust slightly harder to remove, vine-thatchings sturdier.
Lightning causes forest fires, forest fires need sapient intervention.
