As it turns out even touching the axe to the tree creates a visible notch and touching it again makes the notch bigger after about ten touches the entire tree transmutes into a number of wood and acorn items that magnet together and fall to the ground.

Convenient! Are there any other plants around to test this on?

There are more trees and also some small bushes and wildflowers. Aside from the trees most of them just vanish instead. In one case a bush is replaced with a strange worm about as long as her shin and a couple inches thick. In another there's a giant grasshopper the size of her hand. Both are alive.

Ooh, grasshopper! Now a crispy bug.

Indeed, the world offers no guarantees about how useful the burnt bug is.

Well, as long as it doesn’t randomly disappear, Kalryi will have a snack!

It's mundane food there's no special effects.
