In the deeper canons of the Blue Mountains the lowland fir (Abies 

 grandis) is the dominant tree. These trees reach quite a large size, 

 trunks estimated at over four feet in diameter being seen. Near Horn- 

 peg Falls this type of forest is well developed. However, there are 

 many open places washed out by the stream or due to the action of 

 former fires. Associated with the lowland fir are Douglas spruce 

 (Pseudotsuga taxifolia), yellow pine (Pinus ponderosa), western yew
