Bush missing from Beta

Since this semester has started I’ve been noticing bushes disappearing from the Beta house. I live on 15th past Indianola so this is part of my daily walk. The bushes are always completely uprooted in the morning. I mean there has only been 2-3 taken but why would a whole bush been taken?
I’ve heard some rumors that frats make their pledges eat the entire bush, wood and leaves included. Can anyone give me more info about this?
