* show no comparable longevity.

Tulip poplar

* affect ozone concentrations in various interactive ways.
* appear to be especially susceptible to heavy feeding by some species of loopers.
* are often under stress from human activities.
* contribute significantly to the quality of life in our communities.
* face dangers beyond pollution, road salt and poor soil conditions.

Vigorous tree
* Some vigorous trees show growth
  - rapid growth
* can often withstand severe defoliation for a few years.
* tend to be damaged less by floods than stressed trees.

Washington hawthorn tree
* attain height.
* bloom in late springs

Weakened tree
* are more susceptible to bark beetle attacks
  - disease and other insect damage
  - secondary pests such as wood borers or root diseases
  - subject to other diseases and insect infestation
  - susceptible to disease and insect infestations
* become more susceptible to environmental stresses and secondary pathogens
  - vulnerable to drought, frost, fungi, and insects
* have difficulty defending against other forest pests, disease, and drought.

White alder
* good indicator of the presence of flowing surface water.
* has a quick growth and a relatively short life span, as do most riparian trees.

### plant | tracheophyte | tree:

White mangrove
* Most white mangroves produce flowers
  - white flowers
* Some white mangroves have aerial roots
* are the furthest inland and have the least influx of salt water
  - unique because they can get rid of salt through their leaves
