The biological community changes again as one moves from the city to the suburbs. Around all cities is a biome called the "suburban forest". The trees of this forest are species that are favored by man, and most of them have been deliberately planted. Mammals such as rabbits, skunks, and opossums have moved in from the surrounding countryside. Raccoons have become experts at opening garbage cans, and in some places even deer wander suburban thoroughfares. Several species of squirrel get along nicely in suburbia, but usually only one species is predominant in any given suburb -fox squirrels in one place, red squirrels in another, gray squirrels in a third – for reasons that are little understood. The diversity of birds in the suburbs is great, and in the South, lizards thrive in gardens and even houses. Of course, insects are always present.
There is an odd biological sameness in these suburban communities. True, the palms of Los Angeles are missing from the suburbs of Boston, and there are species of insects in Miami not found in Seattle. But over wide stretches of the United States, ecological conditions in suburban biomes vary much less than do those of natural biome. And unlike the natural biomes, the urban and suburban communities exist in spite of, not because of, the climate "> The biological community changes again as one moves from the city to the suburbs.

Dịch : Cộng đồng sinh vật thay đổi lại khi 1 loài chuyển từ thành phố tới ngoại ô. Bao quanh những thành phố là 1 quần xã sinh vât được gọi là ‘rừng ngoại ô’. Những loài cây trong rừng là những loài được lòng con người, chúng được trồng và chăm sóc có chủ đích. Những động vật có vú như như thỏ,chồn thì tới từ những vùng nông thôn xung quanh. Gấu trúc trở thành chuyên gia trong việc cậy bới thùng rác, thậm chí nai đi lang thang trên các tuyến đường phố. Một vào loài sóc thích nghi tốt với vùng ngoại ô, nhưng chỉ có 1 loài là chiếm ưu thế trong bất kì 1 khu vực ngoại ô nào đó- loài sóc cáo ở 1 vùng, sóc đỏ ở 1 vùng khác và sóc xám ở 1 vùng thứ 3 -lí do này nay vẫn chưa giải thích được. Sự da dạng số loài chim ở ngoại ô là rất lớn, và ở miền Nam, thằn lằn phát triển mạnh mẽ ở vườn và thậm trí trong nhà. Đương nhiên, côn trùng thì vẫn luôn hiện diện
Có sự giống nhau kì lại về mặt sinh học trên những quần xa ngoại ô này. Thật vật, sự giàu tài nguyên sinh vật ở Los Angeles đang mất dần từ Boston, và có những loài côn trùng ở Miami không được tìm thấy ở Seattle. Nhưng ở những vùng rộng lớn của Hoa Kỳ, các điều kiện sinh thái ở quần xã sinh vật ngoại ô biến đổi ít hơn nhiều so với quần xã sinh vật tự nhiên. Và không giống như quần xã sinh vật tự nhiên, cộng đồng sinh vật thành thị và ngoại ô tồn tại không bị ảnh hưởng bởi khí hậu
