Data from: Annual Compensation for Floral Herbivory by an Iterocarpic Thistle

We tested the extent to which reproductive effort by an iterocarpic native thistle Cirsium undulatum provided within-season tolerance for insect floral herbivory through plant response to apical damage. We imposed apical damage and used insecticide to reduce herbivory damage to manipulate plant response and potential outcomes in reproductive compensation. Data include: 1) detailed size and fecundity data per plant individual under different treatments; and 2) insect damage score and seeds produced per individual flower head.

Intended Use	These data provide a 2-year snapshot of plant survivorship and fecundity outcomes under different levels of insect herbivore pressure.
Use Limitations	As this dataset reflects 2 years of within-season performance for an iterocarpic species, estimates do not reflect lifetime fitness.
