Why rows of trees planted in coastal areas to check wind movement not called intercropping?

Rows of trees planted in coastal areas to check wind movement are typically referred to as windbreaks or shelterbelts, not intercropping. Intercropping involves growing two or more crops in proximity for benefits like increased yields and pest control, while windbreaks focus specifically on environmental protection and stabilization. The primary purpose of these tree rows is to reduce wind speed and protect the land, rather than to cultivate multiple crop species together.
