"The first colonies were distributed at wide intervals on islands along the entire coast of Tamriel. Later inland settlements were founded primarily in fertile lowlands in southwest and central Tamriel."

"Wherever the beastfolk encountered the Elves, the sophisticated, literate, technologically advanced Aldmeri cultures displaced the primitive beastfolk into the jungles, marshes, mountains, and wastelands."

-Before the Ages of Man

These quotes basically confirm that the Aldmer only settled in a smaller portion of Tamriel and kicked out all of the beastfolk they found in "their land" who seemingly had to settle in areas such as Blackmarsh and Elsweyr.
