The bits of wood

What you can see here is a balsa plank for the access to the gun cradle and various roots. By making my garden earlier this year I found out that strawberry roots looked somewhat like willows! not sure about that, but then here we go.. Notice the white colour of the trunk. When all the bark is gone, trees in marshes tend to look like those.. Now Iw ill see if this colour jut fits with the global colour sheme.
