The document discusses three tree species: eastern hemlock, red maple, and Russian olive. It notes that the future of eastern hemlock is uncertain due to the spread of the hemlock woolly adelgid. It provides additional names and details about the ecological adaptability of red maple. The summary concludes that Russian olive is a hardy and vigorous tree that grows in many soil types and its tolerance of salt makes it suitable for use along highways.

2. Eastern Hemlock
The future of eastern hemlock in question due to the spread
of the hemlock woolly adlegid, an accidentally introduced
sap-feeding insect.

3. RED MAPLE
Red maple (Acer rubrum) is also
known as scarlet maple, swamp
maple, soft maple, Carolina red
maple, Drummond red maple, and
water maple (33). ... It has great
ecological amplitude from sea level
to about 900 m (3,000 ft) and
grows over a wide range of
microhabitat sites.

4. THIS IS A HARDY AND VIGOROUS TREE AND IT GROWS
EASILY IN MANY KINDS OF SOILS. ITS TOLERANCE OF
SALT MAKES THIS A VERY USEFUL TREE ALONG MID-
WESTERN HIGHWAYS WHERE DE-ICING SALT DAMAGES
MANY TREES. LANDSCAPERS LIKE THE RUSSIAN OLIVE
FOR ITS UNUSUAL COMBINATION OF GRAY FOLIAGE,
SILVER-WHITE FLOWERS, AND SILVER-SCALED FRUIT,
WHICH EVENTUALLY TURN REDDISH.
