Fell trees and gather them up. That's called lumbering. Or if you cut them all down and take every last one, it's deforestation and you should be ashamed!
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own.
森林を伐採する際は、事前に届け出が必要です。
Notification is necessary before felling a forest.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up whatever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
