4. Coastal Environment Zone Volume Two 4.3.8.5. Batters and filled areas must be designed and constructed to ensure they are stable and remain effective after completion of harvesting. 4.3.8.6. Water control measures and sediment control measures must be constructed and maintained in all areas disturbed by any excavation or filling undertaken on the land such that all areas are stable. 4.3.8.7. All trees must be felled away from a river (except an ephemeral river, or intermittently flowing river when not flowing), lake, Significant Wetland or the coastal marine area. 4.3.8.8. No tree or log must be dragged through the bed of a river (except an ephemeral river or intermittently flowing river, when not flowing), lake or Significant Wetland or through the coastal marine area. 4.3.8.9. Trees, slash and soil debris must: (a) not be left within 8m of, or deposited in, a river (except an ephemeral river or intermittently flowing river when not flowing), lake, Significant Wetland or the coastal marine area; (b) not be left in a position where it can enter, or be carried into, a river (except an ephemeral river), lake, Significant Wetland or the coastal marine area; (c) be stored on stable ground; (d) be managed to avoid accumulation to levels that could cause erosion or instability of the land. 4.3.8.10. Wheeled or tracked machinery must not be operated in or within 8m of a river (except an ephemeral river or intermittently flowing river, when not flowing), lake, Significant Wetland or the coastal marine area. 4.3.8.11. Harvesting must not cause any conspicuous change in the colour or visual clarity of a flowing river after reasonable mixing, or the water in a Significant Wetland, lake or the coastal marine area, as measured as follows: (a) hue must not be changed by more than 10 points on the Munsell scale. (b) the natural clarity must not be conspicuously changed due to sediment or sediment laden discharge originating from the harvesting site. (c) the change in reflectance must be <50%. 4.3.8.12. Water control measures must be designed and implemented to ensure they remain effective after completion of harvesting. 4.3.9. Conservation planting. 4.3.9.1. The following species must not be planted: (a) Douglas fir (Pseudotsuga Menziesii ); (b) Lodgepole pine (Pinus contorta ); (c) Muricata pine (Pinus muricata ); (d) European larch (Larix decidua ); (e) Scots pine (Pinus sylvestris ); (f) Mountain or dwarf pine (Pinus mugo ); (g) Corsican pine (Pinus nigra ). 4 – 10
