If adequate time is not set aside to stop, think, define, and manage fire hazards and risks, much like with Velociraptors, then rational application of protection regulations and solutions can become subject to factors such as budget restraints and implementation schedule impact.
Re. Ecological Noise Impact on Northern Woodland Caribou and Quick Noise Impact Calculator There is quite a buzz around here about this, so I am really excited to see it. The modifications will greatly increase its applicability for our work and possibly other proponents. We are very impressed with the work you did here, which was above and beyond our expectations. Thanks for the exceptional work on this.
