/diy/ - Do It Yourself

I know this is an incredibly dumb question, but I’m trying to figure out the actual name of this wooden barrier placed on the outside of new construction so I can figure out how best to remove it. This is placed on the exterior of my new home’s backdoor and, now that I’m adding some stairs to the yard, I’m trying to figure out how best to remove it without annihilating my trim. Sadly, ‘wooden barricade exterior new construction’ isn’t the most targeted search term on Youtube.

Thanks for any help!
