Tri-City Ecology Center (TCEC) | Conservation, Preservation, Education

  • About

The natural environment of Fremont, Union City and Newark — like the rest of the Bay Area — is under intense developmental pressure. Rapid growth imperils habitats, from the hills to the Bay itself.

Founded in 1971, the Tri-City Ecology center (TCEC) is your local leader in advocating sound environmental policies that preserve and maintain unique natural resources, clean air, clean water, and a high quality of life.

Please join us in protecting our environment!
