POPLAR-BIRCH TYPE 



56 



Chandos. — An old burn in the northwestern portion of Chandos contains 7,800 

 acres and it extends over 2,500 acres in the adjoining township of Cardiff. The 

 average age of the poplar now occupying the area is 26 years. Frequent pine seed 

 trees remain, and as a whole the area is fairly re-stocked. The young growth 

 exhibits a number of site classes, viz ; the higher ridges, (originally evidently 

 covered by hardwoods with only scattering coniferous growth); the lower ridges, (ori- 

 ginally covered with pine) ; the benches above the streams, and the immediate 

 banks of the streams. Sample plots were made in these sites with the results given 

 in the tables below.

These plots are fairly representative of the old bum in this region and it will 



be seen from them that the sugar maple is replacing itself in the probable original 



quantities (page 47) on its characteristic site. The low sandy ridge is the best site 



or poplar and here the stands closely approximate the average composition usually
