4.6.4 Waterfowl The risk to waterfowl in the event of an oil spill at three selected points in Site 3 is shown in Figure 21. 41 Road Construction Stressor We have based our road construction simulation on a scenario wherein the road that is presently under construction would connect the dock located on the Ob’s right bank with Selyairovo settlement (also located on the right bank). We have applied similar principles to our ecological risk assessment as described in the site 1 section (see Figure 22). Road construction in a specific location will have less effect compared to Site 1. The road in Site 3 crosses through the forest that serves as a noise absorber which makes it possible to restrict the area of road impact. In addition, the section crossed by the road is an area of high ecological resilience which also serves as a factor that decreases the overall road’s impact on the environment. Potential ponding that will eventually develop should not be classified as a significant stressor for waterfowl due to the aforementioned reasons, while gradual disappearance of the screen (forest) would introduce changes in the impact only after several years.
