An experimental approach for crown to whole-canopy defoliation in forests

نویسندگان

چکیده

Canopy defoliation is an important source of disturbance in forest ecosystems that has rarely been represented large-scale manipulation experiments. Scalable crown to canopy level experimental needed disentangle effects variable intensity, timing, and frequency on structure, function, mortality. We present a novel pressure washing-based method can be: implemented at the canopy-scale, throughout volume, targeted individual leaves/trees, completed within timeframe hours/days. Pressure washing proved successful producing consistent leaf-level whole-canopy with 10-20% reduction leaf area index surface removal across branches species. This allows for stand-scale experimentation forested potential broad application. Studies utilizing this standardized could promote mechanistic understanding ecosystem structure function development synthetic types, ecoregions, sources.
