Dataset containing fitting equations from linear regression models for predicting throughfall from gross rainfall for multiple woody and non-woody plant species -i.e. sycamore, ash, goat willow, basket willow and herbs. The equations were fitted per tree species and individual. Throughfall is a relevant eco-hydrological mechanism related to rainfall partitioning at the tree's canopy. Throughfall is basically the amount of rain passing through the canopy without being intercepted by the leaves or woody parts.
