Tree Retention in SMZ

A. For Class 1 streams and lakes, at least 50 percent of trees greater than or equal to 8 inches diameter at breast height (DBH) must be retained on each side of stream or 10 trees per 100 feet, whichever is greater.

A. For Class 2 streams, at least 50 percent of trees greater than or equal to 8 inches DBH must be retained on each side of stream or 5 trees per 100 feet, whichever is greater.

A. For Class 1, 2, and 3 streams, lakes, and other bodies of water, shrubs and submerchantable trees must be retained for the full width of the SMZ.

B. Extended for wetlands = retention requirements for entire SMZ.

B. Extended for slope = retention requirements first 50 feet.

B. In addition, for Class 1 and 2 stream segments:

If the minimum number of trees greater than or equal to 8 inches DBH are not present, then retain the minimum number of trees with the largest DBH available.

Retain trees representative of the size and species of the pre-harvest stand, favoe leaving bank-edge trees, those leaning toward stream, those that will fall into stream and concentrate retained trees within 50 feet of stream.
