|Eucephalus vialis produces only disc flowers|
Our work with Eucephalus vialis this year has been to monitor sites where forest thinning has occurred. IAE research that took place between 2001 and 2010 indicated that thinning treatments (which increased light penetration) reduced mortality, increased plant size and increased the number of flowers per plant. Thinning also increased the abundance of native grasses, forbs and shrubs. There were slight increases in invasive plants specializing in edge habitats such as St. John's wort, blackberry and false-brome. Burning, as it was conducted in these plots in previous years, was found to have no significant effect as a restoration treatment on Eucephalus vialis.
