|discussion=<p>Of conservation concern.</p><!--
--><p><i>Thalictrum cooleyi</i> occurs commonly on Grifton soil and is associated with some sort of disturbance, including clearings, edges of frequently burned savannahs, roadsides, and powerline rights-of-way that are maintained by fire or mowing. Silvicultural and agricultural practices and their associated suppression of fire have seriously affected populations of <i>T. cooleyi</i>. Furthermore, fruit production appears to be quite low in the species (S. W. Leonard 1987).</p><!--
--><p>Leaves of <i>Thalictrum cooleyi</i> have fewer leaflets than other species of <i>Thalictrum </i>sect.<i> Leucocoma</i>.</p>
