Plant Native Trees Instead of Invasive Species: A List of Both Types
My lovely New York City street is filled with towering trees. But unlike the easily identifiable oak and catalpa of my youth, many of these trees do not belong here in the U.S. They are an invasive species. Choosing to plant only native species has many natural benefits.
What is an Invasive Species? What is a Native Species?
- According to the U.S. government, an invasive species in not native to the ecosystem being considered and the introduction of the species can cause or is likely to cause harm that is economic, environmental and is also harmful to human health.
- Native trees occur naturally in a particular ecosystem. The tree or plant originated there without human assistance. Keep in mind too, that plants growing in one part of the U.S. can be considered invasive in another part. Different parts of the U.S. are at different elevations and have different soil types and weather patterns.
How Did These Trees Get Here?
Contrary to popular belief, invasive trees were not an accident. They were brought here intentionally. According to the Brooklyn Botanic Garden, nearly half of the most harmful invasive plants degrading our natural habitats throughout the U.S. were brought here intentionally for horticultural purposes. Many are still being sold for erosion control and simply to look good in the garden.
For example, highway departments, after building new roads, often chose invasive plants in order to establish fast-growing ground covers, especially on slopes.
See link below about the Meyer Lemon Tree and harm caused thanks to a USDA (United States Department of Agriculture) worker who decided to bring it here to the U.S. from China.
How Do They Cause Damage?
When planted in a new ecosystem, nonnative species may displace native trees by growing taller, wider, faster and by creating shade cover over the native species. As a result, the nutrient cycle of native plants is affected, which can also have a devastating effect on animals.
Damage caused by invasive plants do about $120 billion dollars of damage annually. Additionally, approximately 42 percent of threatened species on the U.S. List of Endangered and Threatened Species are there because of nonnative species. (See link below about how animals get on the endangered species list).
Invasive plants are difficult to control and hard to eliminate. It's best to avoid them.
Is There Any Way I Can Easily Tell if a Tree is Not Native?
A quick way to tell is by the name. Often the place of origin is in the name. For example, the English Ivy - a vine - is not native as the name indicates. (I watched the ivy twine its way up a neighbor's native tree and destroy it). Trees that are not native include the European Elder and the Australian Pine. More trees are listed below on the invasive list.
What are the Benefits?
Native trees will preserve the natural beauty of your community as well as the natural balance between all native species and all the birds, butterflies and others that depend on the various species. They are also easier to grow and maintain.

Yes, the toilet lid must be put down after use. It's not yet a silly law but it makes so much sense. For example, when you flush, a bacteria-filled mist is created.
Planting native shrubs and avoiding invasive species is the humane thing to do. Native shrubs prove food for animals and insects that belong here, while providing us all with natural beauty in a low-maintenance setting.
That not-so-innocent roll of toilet paper may very well be the cause of you itching until you feel like screaming. If you have tried a new brand - like the mistake I made using a so-called 'earth friendly' brand - well,...
