a   Recently disturbed forestland (cutover, wildfire, insect killed) that currently has no forest cover but is expected to revert to forest.

b   Non-productive forest is considered non-harvestable, but may be relevant Red Crossbill habitat.

c   Total area of forested land in Newfoundland is ~5.2 million hectares.

 

Notes:

1.       Total productive forestland for insular Newfoundland is ~3 million hectares. Total non-productive forestland for insular Newfoundland is ~2 million hectares. Insular Newfoundland is ~11.2 million hectares in size.

2.       Total forest cover, including productive and non-productive forestland, for insular Newfoundland = 5.2 million hectares.

3.       Softwood-dominated forest at age classes 3–5 (i.e., cone-bearing) combined with non-productive softwood forest = 32.5% coverage of insular Newfoundland.

4.       Non-intensively inventoried land for insular Newfoundland = ~3.2 million hectares.

5.       In the case of mixed stands (mixture of hardwoods and softwoods), the leading species is not shown.

6.       Age classes are in 20-year increments (e.g., “1” = 0–20 years, “2” = 21–40 years).

7.       The data set reflects the forest as artificially updated to December 2005 for the 2006–2010 wood supply analyses.

8.       The data do not include the two national parks or those parts of the island that remain uninventoried.

9.       The break-out of the age class “5” into multiple categories up to age class “8” has not been completed for all districts. Therefore, the table shows “5+.”
