Nice stack of wood.
You have summer grass & weeds already, nice & green

Birch here are in the pollen stage & just budding leaves. ( Achuuuu ! )
Might use some weed killer around them to keep weeds out. May cause a moisture & bug problem.
I put down old carpet, landscape fabric or tarps under the pallets. Keeps the weeds & grass out & good air to the bottoms.
Nice skid-steer, hydraulics are great.
