The purpose of this study was to examine how exposure to two different types of plant-derived smoke (grass smoke and wood smoke) affects the germination of common native and invasive plants found in the northern Great Plains. First, we hypothesize that smoke (both grass-derived and wood-derived) will increase total germination. Second, we hypothesize that wood-derived smoke will influence germination differently than will grass-derived smoke. Lastly, we hypothesize that native and non-native plants will respond differently to the exposure to the two plant-derived smoke treatments.
