Researchers have discovered unsuitable soil at higher altitudes may be halting the advancement of treelines. This finding dispels the commonly held assumption that climate change is enabling trees to move farther uphill and northward. The researchers looked at plant growth at higher altitudes in the Canadian Rockies, grew spruce and fir seedlings at varying elevations and collected soil samples from the same areas to grow spruce seeds in growth chambers .
