Research Applications
Understanding mechanisms behind plant invasion are vital for the management of invasive species. Increased N availability can favour fast-growing invasive plants over slower-growing native plants.
Blumenthal (2009) studied the addition of soil C on N immobilization in invasive plant stands. PRS® Probes detected an average of 73% less N in C-addition plots, indicating N immobilization with C addition. In plots with water addition, C addition reduced biomass and invasion of non-native plants.
PRS® nitrogen supply rates and invasive plant biomass as affected by N and C addition. Error bars are one standard error.
Examples
- Elevated nitrogen effects on Bromus tectorum dominance and native plant diversity in an arid montane ecosystem
- Spatial variability in cost and success of revegetation in a Wyoming big sagebrush community
- Bromus inermis invasion of a native grassland: Diversity and resource reduction
- Non-native competitive perennial grass impedes the spread of an invasive annual grass
- Contrasting effects of resource availability and plant mortality on plant community invasion by Bromus tectorum L
- Does fall prescribed burning Artemisia tridentata steppe promote invasion or resistance to invasion after a recovery period?
- Nitrogen enhances the competitive ability of cheatgrass (Bromus tectorum) relative to native grasses
