Why is someone taking chunks of cedar from my property

Owlie45

People have been taking the old rotted chunks of cedar from my property. And I don't know why.
They gather the chunks into piles and then a while later, days, they are gone. Sometimes they are stabbed in to the ground, I think to dry them.

Any ideas on why they are taking them?

Could be a number of reasons. Could be for mulch. It is generally insect repellent. Could be for storing wool items as a moth repellent
