Intensive Seed Orchard Managment- A Minnesota Example

The St. Francis Seed Orchard was established in 1985, and consists of two, three-acre grafted orchards. One is comprised of 15 white pine clones putatively resistant to blister rust, and the other contains 40 Scots pine clones selected for timber quality. These orchards are intensively managed including cover cropping, mowing, mulching, gopher control, soil sampling, fertilization, irrigation, and pest monitoring. Changes in management with time are also discussed. Additional Keywords: Pinus strobus , Pinus sylvestris , Cronartium ribicola
