Fungal bioluminescence, fireflies, a few fireflies in clearings and caverns, lower forest lit up with fungal lights, bioluminescence a royal blue.
Clear view.
Mid-forest clearings gone, moss on tree trunks and some rocks and above the tree line, plants occasionally droop a bit, normal amount of plants.
Noticeable wind, no lightning, drizzles, room temperature winds.
Rivers are normal and there is morning dew, normal amount of rain for this level, 33% less river strength than usual for this level.
Wood unreliable, 50% 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, cavern entrances are half crusted over, crust normal to remove, vine-thatchings slightly brittle.
Lightning causes forest fires, forest fires stop at rivers.
