Would you expect transcendentalists to support environmental rights today

Absolutely. Transcendentalists believed in the power of nature. Emerson and Thoreau were two major Transcendentalists who loved nature and held it in high esteem. Emerson saw nature as a means by which we can understand not only the physical world, but also the spiritual one. To him, nature was a form of the divine. Therefore, Transcendentalists would absolutely support environmental rights, or anything that aims to protect the environment.
