What's this shrub (1)? Danger of contact dermatitis?
Thank you for the pictures which are very helpful. From the shape of the leaves, this appears to be a Cottonwood sapling which should be able to be removed without concern about skin issues. That being said, we would always recommend that you wear protective clothing when removing, planting or pruning shrubs and trees since each person reacts differently to the contact.
Hope that helps!
