If you still take pokemon lists, perhaps instead of a full forest, we zoom in on a single tree.
Even on such a small scale there are differences in environment, level of sun, height, etc, that can lead different kinds of pokemon to live together.
At the ground level, you see Nincada just emerging from the ground. They sense evolution is near and are migrating to the surface to prepare. A curious Rockruff is watching. A small Petilil is waiting patiently to enjoy the freshly disturbed soil.
A little higher on the trunk, a Helioptile is warming up in the sun. They seem totally unaware of the spinarak creeping closer. In a hollow of the tree a Hoothoot is sleeping, waiting for nightfall to go on a hunt. Skwovet seems eager to join the hollow, but this will no doubt end badly once hoothoot wakes up.
Up in the foliage a lot more pokemon have space to live besides each other. Burmy is collecting leaves for it's cloak while Sewaddle is attempting to perform a threat display, with limited success. Tranquil has built a nest and is sitting on some eggs, fiercely guarding them. A purrloin has climbed up and is sleeping on a branch right next to a Slakoff hanging off of the same branch.
Nature truly is everywhere, and truly is beautiful
(I hope it's ok I went for a more nature documentary writing style instead of just a list?)
yesssss ive been curious if/when someone might touch one something smaller! i think you've done a fantastic job of describing what going on, but i did want to touch on trees a little!
that growth near the bottom of a tree is called a burl, they form from outside stress (likely from insects, illness, or fungal infection) causing a tree to make the grain grow in all sorts of directions, which makes them tough and have interesting patterns!
tree hollows are very similar in nature- usually caused by stress via illness, insects, fungi, fire, lightning, or an old branch falling off to reveal the inside of the tree. this usually only forms in older trees, since only the outermost layers of a tree are actually alive. this means that the deeper, inside layers that are not carrying nutrients can be dug away by animals (or pokemon, in this case) without hurting the tree.
trees are neat! thanks for the suggestion! and it was fun reading it like a nature documentary lol.
