Oak wilt? Sudden Oak Death? How does one tell the difference?

In the past, I have seen oaks die from the botttom up and others who
died from the top down....in the same backyard.

Also, how easily is it spread by using the dead tree for firewood?

Thanks

Using the dead tree for firewood is probably a good thing...that's how
they're attempting to eradicate infected trees in the wild--by burning.

As far as telling the difference between Oak Wilt and SOD, you can tell
by the "sores" on the tree, and at this time by your geography. In
other words, if you don't live in California/Oregon (or parts of
Europe), the chances of you having SOD are basically nill. SOD is a
very new development, and it has not been found, at least to any real
extent, in the wild outside of that range. As for identifying by the
sores, check out this website:

With SOD, there are canker sores which appear to "bleed."

In a "Thank God for small mercies" way, it appears that white oak
species are not susceptible to SOD...it is only the red oaks that are
succumbing.

Live oaks in Ca. Lost mine in 1997.
