After thinning circled trees (rows 4, 6 and 8), 50:50 species diversification is left in the row. A staggered design within the 3 rows is left, increasing growing space without sacrificing density for wind protection.

Staggered win-row design (row 10) increases growing space without sacrificing density for wind protection. As trees in staggered win-row grow into each other the whole circled tree row can be removed without decreasing 50:50 species diversification left in adjacent tree row.

Reasons for understory planting:

  1. Start the next forest cover.
  2. Maintain ground level density to decrease potential weed competition.
  3. Take advantage of pine needle mulch for seedling establishment.
  4. Alternative tree crop: Christmas trees, transplant nursery, small timber, firewood
