Effect of boreal forest logging on nectar production of four understory herbs

► We studied rate of nectar secretion in four abundant bumble bee-pollinated boreal forest understory forbes. ► Nine years earlier, the forest stands had received experimental logging treatments. ► The treatments were: clearcut, 50% green tree retention, and unlogged controls. ► For three of the species, rate of nectar secretion was similar across logging treatments. ► Major habitat change via logging had strikingly little influence on nectar secretion.
