These data were collected for a project comparing the leaf phenology, carbon gain, growth, and freezing susceptibility of invasive and native species. Understory light availability was measured above 80 understory wood shrubs using hemispherical photos, lux sensors, and photosynthetically active radiation (PAR) sensors. Light data was used to compare overstory and understory leaf phenology, and to quantify light available for carbon gain in the understory.
