    4. Loading decks or landings, and log bunching points.
    5. Road construction except when crossing a waterbody.
    6. Site preparation burning on slopes greater than 18%.

Secondary Zone

    The Secondary Zone applies to all intermittent streams, intermittent lakes and sinkholes with intermittent water. In addition, for perennial waterbodies, OFWs, ONRWs and Class I Waters, the Secondary Zone may apply as an “add-on” to the Primary Zone (Figure 1 and Appendix 1).

    For intermittent waterbodies, the Secondary Zone is always at least 35 feet wide on each side of a stream or around the circumference of lakes and sinkholes. Depending on the SSC, the width of the Secondary Zone for intermittent waterbodies may be as much as 300 feet (See Figure 2 and Appendix 1).

    The SSC is used to determine the width of the Secondary Zone, in the case of intermittent waters, as well as the necessity for the Secondary Zone, in the case of perennial waters, OFWs, ONRWs and Class I waters. Generally, the more erodible the soil and the steeper the slope, the wider the Secondary Zone, and/or the wider the entire SMZ. Appendix 1 lists the SSC for all combinations of soil and slope conditions, and provides the width requirements for the applicable Special Management Zone under each condition.

    The Secondary Zone has no timber harvesting limitations - unrestricted selective harvesting and clearcut harvesting are both permissible anywhere within the Secondary Zone. However, the following operational restrictions apply:

Secondary Zone • Operational Restrictions

  1. No mechanical site preparation.
  2. No loading decks or landings.
  3. No site prep burning on slopes greater than 18%.
  4. No roads except for crossings.

Stringer

    The Stringer applies only to intermittent streams, intermittent lakes and sinkholes with intermittent water, and is composed of trees left on or near the bank along both sides of these waterbodies. The Stringer can provide limited food, cover, nesting and travel corridors for a number of animals, especially birds.
