either direction to allow for the selection trees with desirable characteristics.
• Selected leave trees will preferably be phenotypically superior trees that are single and straight stemmed, having crown ratios
greater than 50% and free from any other disease or defect – including forked tops, mechanical damage, crook or sweep,
mistletoe, or rust brooms.

• Cut trees shall include all trees/species from 1 foot tall to 7 inches DBH (Diameter at Breast Height).
• Trees less than 1 feet tall shall not be considered in spacing requirements.
• Trees greater than 8 inches DBH will be ignored in the spacing, except that no leave trees will be selected that are under the
drip line of a tree greater than 8 inches DBH.
• Slash generated by project activities will be removed from stream channels at the end of each operational shift.
• Cut trees will be placed in piles that must be as large as possible, greater than 6’x6’x6’ and located in openings free of
overhanging branches to minimize scorch to remaining trees
• Stump heights must be less than 6 inches on the uphill side and must be severed below the lowest live branch.
