    Abstract
    <jats:p> There are continuum many ≤<jats:sub>B</jats:sub>-incomparable equivalence relations induced by a free, Borel action of a countable non-abelian free group — and hence, there are 2<jats:sup>α<jats:sub>0</jats:sub></jats:sup> many treeable countable Borel equivalence relations which are incomparable in the ordering of Borel reducibility. </jats:p>
