Agrilus planipennis, commonly known as the emerald ash borer, is a green buprestid or jewel beetle native to northeastern Asia that feeds on ash species.
 Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.
 In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area.
 Outside its native range, it is an invasive species and is highly destructive to ash trees native to northwest Europe and North America.
 Prior to being found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America.
 Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control.
Cephalotaxus, commonly called plum yew or cowtail pine, is a genus of conifers comprising 11 species, treated in either the Cephalotaxaceae, or in the Taxaceae when that family is considered in a broad sense.
 The genus is endemic to eastern Asia, though fossil evidence shows it had a wider Northern Hemisphere distribution in the past.
 The species are evergreen shrubs and small trees reaching 1.0–10 m (rarely to 20 m) tall.
Acer grandidentatum (bigtooth maple) is a species of maple native to interior western North America, occurring in scattered populations from western Montana in the United States south to Coahuila in northern Mexico.
 It is closely related to "Acer saccharum" (sugar maple), and is treated as a subspecies of it by some botanists, as "Acer saccharum" subsp.
 "grandidentatum" (Nutt.)
 Desmarais.
Acer circinatum (vine maple) is a species of maple native to western North America, from southwest British Columbia to northern California, usually within 300 km of the Pacific Ocean coast, found along the Columbia Gorge and Coastal Forest.
 It belongs to the "Palmatum" group of maple trees native to East Asia with its closest relatives being the "Acer japonicum" (Fullmoon Maple) and "Acer pseudosieboldianum" (Korean Maple).
 It can be difficult to distinguish from these species in cultivation.
 It is the only member of the "Palmatum" group that resides outside of Asia.

Acer negundo is a species of maple native to North America.
 In Canada it is commonly known as Manitoba maple and occasionally as elf maple.
 Box elder, boxelder maple, ash-leaved maple, and maple ash are its most common names in the United States; in the United Kingdom and Ireland it is also known as ashleaf maple.
Acer spicatum (mountain maple) is a species of maple native to northeastern North America from Saskatchewan to Newfoundland, and south to Pennsylvania.
 It also grows at high elevations in the southern Appalachian Mountains to northern Georgia.
Acer is a genus of trees or shrubs commonly known as maple.
 The genus is placed in the Sapindaceae family.
 There are approximately 128 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America.
 Only one species, "Acer laurinum", extends to the Southern Hemisphere.
 The type species of the genus is the sycamore maple, "Acer pseudoplatanus", the most common maple species in Europe.
Acer saccharinum, commonly known as silver maple, creek maple, silverleaf maple, soft maple, water maple, swamp maple, or white maple—is a species of maple native to eastern and central North America in the eastern United States and Canada.
 It is one of the most common trees in the United States.
Acer rubrum (red maple, also known as swamp, water or soft maple) is one of the most common and widespread deciduous trees of eastern and central North America.
 The U.S. Forest service recognizes it as the most abundant native tree in eastern North America.
 The red maple ranges from southeastern Manitoba around the Lake of the Woods on the border with Ontario and Minnesota, east to Newfoundland, south to Florida, and southwest to eastern Texas.
 Many of its features, especially its leaves, are quite variable in form.
 At maturity it often attains a height of around 15 m .
 Its flowers, petioles, twigs and seeds are all red to varying degrees.
 Among these features, however, it is best known for its brilliant deep scarlet foliage in autumn.
