Hardest hit would be black and green ash
, with projections indicating that the EAB would spare roughly 30-40 percent of the nation's blue ash, and 20-30% percent of its white ash species.
The green ash
in our yard rarely loses its beautiful winged samaras in autumn, so we are treated to the sight of them during the coldest months of the year.
5 mm or 1 mm wide), each containing 10 EAB eggs, and controls where the eggs on 1 piece of filter paper were completely exposed, with 4 replicates of each treatment on each of 5 green ash
About 8 percent of the hardwood trees across Massachusetts are ash trees, and 80 percent of the state's white and green ash
trees are in Berkshire County.
A total of 2,000 pounds of seed mixture was sown and thereafter, 10,000 tree species were planted including White Pine, Loblolly Pine, Northern Red Oak, Pin Oak, Sawtooth Oak, Green Ash
, Button Bush, Indigo Bush and Redbud.
1991) also reported that green ash
was a dominant tree along with species of elm, pecan, sugarberry, and oak.
In some forests, the leafy green ash
trees are just one of a diverse mix of species.
In southeast Michigan, where EAB was first established, scientists have documented 99 percent mortality in forest stands dominated by green ash
(Fraxinus perinsyl-vanica), white ash (Fraxinus americana) or black ash (Frasinus nigra).
The researchers attached cages containing the wasps to green ash
trees infested with EAB larvae between August and October in areas of Michigan and Maryland to assess the wasps' abilities to parasitize the ash borer and survive in those areas.
The scientific name for these two species of trees is Fraxinus americana and Fraxinus Pennsylvania also known commonly as white ash and green ash
Forty-five green ash
(Fraxinus pennsylvanica) street trees in Toledo, Ohio were photographed, measured, and visually rated for conditions related to emerald ash borer (Agrilus planipennis) (EAB) attacks.
In this study, green ash
trees increased the average infiltration rate by 27 fold compared with unplanted controls.
