Ideas to fix spring:
Some types of trees should seed early, and maybe even die off in fall to balance?
Maybe evergreens seed in spring?
Frogspawn suggests that frogs must exist, yet they do not. perhaps they should exist but in much, much smaller numbers?
Insects like dragonflies that do not exist could have fun larval stage counterparts?
Animals like foxes, wolves, bears and hibernating animals would be coming out of dens in spring with their babies.
It's time for baby wild animals tbh imo.
Also, spring mushrooms exist.
