Introduction

I-5 or Interstate 5 is a major highway on the west coast of the United States. It is an important transportation route that runs from the Mexican border in San Diego, California, to the Canadian border in Blaine, Washington. Along the way, many trees have been planted on the highway’s median strip and on the roadside. In this article, we will explore what kinds of trees are planted on I-5 and the benefits they provide.

Benefits of Trees on Highways

Trees are an important part of our environment and ecosystem. They help to clean the air, provide shade, and reduce noise pollution. Trees on highways have additional benefits. They can help to reduce the glare from headlights at night, which can improve visibility and reduce accidents. Trees can also act as a buffer between the road and nearby homes and buildings, reducing the amount of noise pollution that reaches them.

Types of Trees Planted on I-5

Different types of trees can be found along the length of I-5, depending on the climate and location. In southern California, where the climate is warm and dry, you can find palm trees, pepper trees, and eucalyptus trees. In the central valley of California, where the climate is hot and dry in the summers and cool and wet in the winters, you can find almond trees, citrus trees, and olive trees. Further north, in the Pacific Northwest, you can find Douglas fir trees, redwoods, and cedars.

Native and Non-Native Trees

Trees along I-5 can be native or non-native species. Native trees are species that have historically grown in a particular region or environment. Non-native trees, on the other hand, have been introduced from other places or countries. Native trees often have greater benefits and ecological value than non-native trees. In some cases, non-native trees can become invasive and threaten the native ecosystem.

Conclusion

Trees along highways like I-5 provide many benefits to the environment, drivers, and nearby residents. They help to reduce air and noise pollution, improve visibility and safety, and add to the beauty of the landscape. It is important to choose the right types of trees for each location and to maintain them properly to ensure their continued health and benefits.
