Global patterns and drivers of rainfall partitioning by trees and shrubs.

Glob Chang Biol 2021 Jul 6;27(14):3350-3357. Epub 2021 May 6.

CREAF, Cerdanyola del Vallès, Spain.

Spatiotemporal redistribution of incident rainfall in vegetated ecosystems results from the partitioning by plants into intercepted, stemflow, and throughfall fractions. However, variation in patterns and drivers of rainfall partitioning across global biomes remains poorly understood, which limited the ability of climate models to improve the predictions of biome hydrological cycle under global climate change scenario. Here, we synthesized and analyzed the partitioning of incident rainfall into interception, stemflow, and throughfall by trees and shrubs at the global scale using 2430 observations from 236 independent publications.

Elevated CO did not affect the hydrological balance of a mature native Eucalyptus woodland.

Glob Chang Biol 2018 07 17;24(7):3010-3024. Epub 2018 Apr 17.

Hawkesbury Institute for the Environment, Western Sydney University, Penrith, NSW, Australia.

Elevated atmospheric CO concentration (eC ) might reduce forest water-use, due to decreased transpiration, following partial stomatal closure, thus enhancing water-use efficiency and productivity at low water availability. If evapotranspiration (E ) is reduced, it may subsequently increase soil water storage (ΔS) or surface runoff (R) and drainage (D ), although these could be offset or even reversed by changes in vegetation structure, mainly increased leaf area index (L). To understand the effect of eC in a water-limited ecosystem, we tested whether 2 years of eC (~40% increase) affected the hydrological partitioning in a mature water-limited Eucalyptus woodland exposed to Free-Air CO Enrichment (FACE).

Mixed forest plantations can efficiently filter rainfall deposits of sulfur and chlorine in Western China.

Sci Rep 2017 01 30;7:41680. Epub 2017 Jan 30.

Key Laboratory of Ecological Forestry Engineering, Institute of Ecology and Forestry, Sichuan Agricultural University, Chengdu 611130, China.

Forest filtering is a well-known and efficient method for diminishing atmospheric pollutant (such as SO and Cl) inputs to soil and water; however, the filtering efficiencies of forests vary depending on the regional vegetation and climate. The rainy area of West China has suffered from heavy rainfall and human activity, which has potentially resulted in large amounts of sulfur and chlorine deposition, but little information is available regarding the filtering effects of typical plantations. Therefore, the migration of SO and Cl from rainfall to throughfall, stemflow and runoff were investigated in a camphor (Cinnamomum camphora) plantation, a cryptomeria (Cryptomeria fortunei) plantation and a mixed plantation in a 9-month forest hydrology experiment.

The role of stable isotopes in understanding rainfall interception processes: A review.

WIREs Water 2017 Jan;4(1):1-17

National Health and Environmental Effects Research Laboratory, Western Ecology Division, US Environmental Protection Agency, Corvallis, OR, USA.

The isotopic composition of water transmitted by the canopy as throughfall or stemflow reflects a suite of processes modifying rainfall. Factors that affect isotopic composition of canopy water include fractionation, exchange between liquid and vapor, and selective transmittance of temporally varying rainfall along varying canopy flowpaths. Despite frequent attribution of canopy effects on isotopic composition of throughfall to evaporative fractionation, data suggest exchange and selection are more likely the dominant factors.

The importance of considering rainfall partitioning in afforestation initiatives in semiarid climates: A comparison of common planted tree species in Tehran, Iran.

Sci Total Environ 2016 Oct 16;568:845-855. Epub 2016 Jun 16.

Department of Natural Resource Sciences, Faculty of Science, Thompson Rivers University, Kamloops, Canada.

As plantations become increasingly important sources of wood and fiber in arid/semiarid places, they have also become increasingly criticized for their hydrological impacts. An examination and comparison of gross rainfall (GR) partitioning across commonly-planted tree species (Pinus eldarica, Cupressus arizonica, Robinia pseudoacacia, and Fraxinus rotundifolia) in semiarid regions has great value for watershed and forest managers interested in managing canopy hydrological processes for societal benefit. Therefore, we performed a field study examining GR partitioning into throughfall (TF), stemflow (SF), and rainfall interception (I) for these species in the semiarid Chitgar Forest Park, Tehran, Iran.

A review and evaluation of forest canopy epiphyte roles in the partitioning and chemical alteration of precipitation.

Sci Total Environ 2015 Dec 4;536:813-824. Epub 2015 Aug 4.

Dept. of Natural Resource Sciences, Thompson Rivers University, Kamloops, BC, Canada.

Interactions between precipitation and forest canopy elements (bark, leaves, and epiphytes) control the quantity, spatiotemporal patterning, and the chemical concentration, character and constituency of precipitation to soils. Canopy epiphytes exert a range of hydrological and biogeochemical effects due to their diversity of morphological traits and nutrient acquisition mechanisms. We reviewed and evaluated the state of knowledge regarding epiphyte interactions with precipitation partitioning (into interception loss, throughfall, and stemflow) and the chemical alteration of net precipitation fluxes (throughfall and stemflow).

Modeling the early-phase redistribution of radiocesium fallouts in an evergreen coniferous forest after Chernobyl and Fukushima accidents.

Sci Total Environ 2015 Oct 22;529:30-9. Epub 2015 May 22.

Institute of Radiation Protection and Nuclear Safety, CE Cadarache-Bat 153, BP3-13115 St-Paul-lez-Durance Cedex, France.

Following the Chernobyl accident, the scientific community gained numerous data on the transfer of radiocesium in European forest ecosystems, including information regarding the short-term redistribution of atmospheric fallout onto forest canopies. In the course of international programs, the French Institute for Radiological Protection and Nuclear Safety (IRSN) developed a forest model, named TREE4 (Transfer of Radionuclides and External Exposure in FORest systems), 15 years ago. Recently published papers on a Japanese evergreen coniferous forest contaminated by Fukushima radiocesium fallout provide interesting and quantitative data on radioactive mass fluxes measured within the forest in the months following the accident.

[Rainffall interception model of forest canopy: a preliminary study].

Ying Yong Sheng Tai Xue Bao 2005 Sep;16(9):1633-7

Chinese Academy of Forestry, Beijing 100091, China.

Canopy interception is an important hydrological process in forest ecosystem, and its modelling is of significance to understand and estimate the rainfall interception by the canopy. In this paper, a canopy rainfall interception model was established by dividing a rain incident into a set of short period, calculating the rainfall distribution intercepted by the canopy, and educing the process of the rain incident. This model considered the effects of the dryness of canopy and trunk on the evaporation from wet canopy and trunk during one rain incident, and introduced two factors, leaf area index (LAI) and surface area of trunk per unit area of ground (SAI), when computing the evaporation.
