You've written that great plant poem, botanical story, essay or memoir--now what?
Some tools for submitting to literary magazines include:
Their database will let you search literary magazines by topics and genres as well as by other criteria, such as whether the journal allows you to submit to other journals simultaneously.
Another site that allows you to search literary magazines, calls for submissions, and writing contests.
A searchable database of magazine reviews with some more specifics on the kinds of writing particular magazines might be publishing.
Literary Outlets for Environmental Writing
A list of links to publications devoted to essays, articles, short stories, or poetry about ecology and the natural world.
A portal for electronic submissions that is used by the vast majority of literary magazines. Getting an account is easy and free. You can search their database for open calls for submissions and check on the status of any pieces you have submitted through the portal. They also will send you the weekly Submishmash Newsletter via e-mail, which contains current calls for submissions.
A free tool for logging and tracking your submissions and for finding out how long it takes magazines to respond. Not every magazine or anthology will have an entry here, so it is best to also keep a separate list or spreadsheet of all of your submissions in a notebook or on your computer. This becomes especially important when one of your pieces has been accepted somewhere, so that you will remember where you need to withdraw simultaneous submissions of your manuscript.
Find out wether your form rejection was the journal's "standard" rejection or whether they truly meant to encourage you to submit more work to them by sending you a "higher tier" rejection.
