Figure 26. — Most black spruce swamps that were not burned subsequent to 

 logging have restocked. This area was clear cut about 20 years prior to the 

 time this photograph was taken. The present stand is composed partly of ad- 

 vance reproduction that survived the logging operation and partly of repro- 

 duction that seeded-in later.
