"It was very scrappy - a typical derby game," Pearce told the club's official website. "There was a lack of quality from both sides and when we got our noses in front I was hoping we would go on to secure the three points.
"Derby will probably come away from this happier than we are but I think, over the 90 minutes, a draw was a fair result. We'll learn our lessons and, once again, I think we can improve on that performance."
Forest remain at the top of the Championship table following the draw, one point ahead of Norwich City.
