|
Snags
|
|
Why were snags removed prior to 1970? (3)

|
How do you protect snags from prescribed fire?
|
"Ring" bases of snags by removing fuel from around the base immediately prior to burns
|
|
How do you create snags with prescibed fire?
|
Burn in mixed pine-hardwood forests because of the susceptibility of hardwoods to fire.

|
12-24 DBH
|
|
How is Saw timber management best for woodpeckers? (2)
|
1) Stands are more open due to thinning, burning, and herbiciding.
2) Larger/older trees provide nesting, Roosting, foraging substrates. |
|
Why are hardwood trees important to woodpeckers?
