White Pine Management has been recently added to the
Province’s silviculture program.
|
| |
Species is valuable but silvicultural enhancement has
been ignored until recently because of severe disease problems.
|
| |
White Pine Blister Rust, introduced from Europe in the
early 1900's, has decimated White Pine by killing most of the regeneration.
|
A better understanding of the disease
and other issues has led to the implementation of new silvicultural prescriptions:
|
| |
Planting 400-700 pine seedlings per hectare in
combination with spruce plantations
|
| |
Genetic tree improvement programs - seed collection
programs which target disease resistant trees
|
| |
Forest improvement programs to favour White Pine crop
trees
|
| |
Pruning of juvenile trees to reduce their susceptibility
to disease |
