What accounts for the different colors of table olives?
green: picked at full size before ripening begins
red/brown: semi-ripe; picked as they are beginning to ripen and change from green to brown
black: picked at full maturity when purple to brown/black in color

Saint Paul in May of 2009
What accounts for its rapid spread in N.A.?
Infested trees were used for firewood.

What would be three clear indicators an ash tree is infested with EAB?
Creates extensive S-shaped galleries
First outward symptoms include: 1) D-shaped exit holes from where the larvae pupate and exit as full-grown adults
2) epicormic branching (emerging from under the bark) on trunk (2nd and 3rd years after infestation)
-looks like knobs or bunches of green leaves popping out of the side of the trunk
3) Increase in woodpecker activity
