That is the Ks Forestry seedling price list. There are trees/shurbs that would be great to plant for poultry to use to escape from winged predators, wind breaks, etc.
Thanks so much for this info! Believe this is where my parents bought trees for a shelter belt they grew on the N side of some property they own. Put it in 20 years ago (I had to help water the babies) & you wouldn't believe how big the evergreens are now!
