Canopy research
Canopy research is the field of scientific research based upon data collected in the canopy of trees.
==Objects==
* Description of plant and animal species residing in the tree-summits. Mainly ancient forests and tropical forests are studied.
* Study of forest ecosystem dynamics, change drivers and other factors that shape forest systems.
* Collection of meteorological data. Meteorological studies can help researchers measure the efficacy of forest canopies in offsetting global climate change. Researchers at the Agricultural Research Service have calibrated a model for forest canopies that measures and estimates the amount of carbon a forest canopy absorbs/releases due to photosynthesis/respiration. The research found that the forest canopy shifted from a carbon “sink” (of net carbon absorption due to photosynthesis) to a carbon “source” (of net carbon respiration) following the defoliation of the canopy due to the gypsy moth. () This research helps scientists determine the role of trees in offsetting carbon released into the atmosphere, which contributes to global warming, and the biological influences that impact it.
