UMR floodplain forest is primarily composed of silver maple, green ash
, and American elm, with cottonwood, black willow, river birch, swamp white oak, hackberry (Celtis occidentalis), and box elder (Acer negundo) common in some areas (Knutson and Klaas, 1998; Urich et al, 2002).
One 4th instar was observed after it was attracted to a fermented mix of bananas and beer used to collect underwing moths on the trunk of a green ash
tree (Fraxinus pennsylvanica Marsh.
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).
White, black and green ash
are the most common species in New York State.
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.
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.
Herman's Prairie Spire green ash
is the most popular and well-liked of the many green ash
Joining this forest mosaic at sites with prolonged, but not continuous, standing water, are communities of such characteristic species as silver maple, cottonwood, sycamore, green ash
(Fraxinus pennsylvanica Marshall), overcup oak (Quercus lyrata Walter), pecan, shellbark hickory (Carya laciniosa (Michx.
Eight green ash
trees were harvested from Kensington Metro Park near Brighton, Michigan, in early winter 2004, when most EABs were overwintering as fully developed larvae.
Common trees on ridges included boxelder (Acer negundo), red maple (Acer rubrum), sugarberry (Celtis laevigata), green ash
(Fraxinus pennsylvanica), sweetgum (Liquidambar styraciflua), and American elm (Ulmus americana).
Zones 1, 2: Good choices include American hornbeam, Eastern redbud, honey locust, Japanese pagoda tree, little-leaf linden, and 'Marshall' seedless green ash

Then they began planting trees such as cypress, tulip poplar, green ash
, and several Japanese maples.
