Hello, hoping someone here can help me please ID a 'tree' growing on my property. (I know nothing about plants and have basically come here just for help). Pics attached. I say 'tree' in quotation marks as the trunk system is almost vine like - multiple branches at ground level. Leaves are palm sized and thorns on the new growth. In the far shot attached, the green dot indicates 6 foot from ground, as an indication of current height. It's in a gully that is almost constantly wet or damp. It's doing a great job of stopping the gorse from spreading, but need to know if it's invasive or noxious and should probably remove it (versus pruning). Thanks everyone. I appreciate your time to read this.
