Do you have Firebug installed? If not, you definitely need to get that.
The console tab is invaluable in debugging Ajax.

This is interesting. I'm not sure what the impact would be of mixing
form_tag, which includes the url ('/trees'), with submit_to_remote, which
also includes a url. Especially since they're different urls in your case
(a POST to trees is going to naturally invoke the 'create' action, not the
'new' action. You might try just using form_remote_tag instead.

You didn't show it, so I'll assume you have a <div id="newtree"> element on
the page, and that you have a newtree.rhtml file in views/user/trees/. If
either of those is not true, your Ajax definitely won't work.
Bottom line, though, is get Firebug installed in FireFox and see what it's
telling you.
HTH,
