Trees form the terrestrial interface with the atmosphere in forested regions. The electrical properties of trees may influence their response to atmospheric conditions and potentially lethal phenomena (e.g., lightning). We review the literature describing electrical properties of trees and provide a tabular summary of the methods and goals of each study. We hypothesized that electrical resistivity varies consistently among species and between growth forms. We surveyed resistivity of eight tree… Expand

Effects of lightning on trees: A predictive model based on in situ electrical resistivity
TLDR
This study provides the first quantitative mechanism describing how differences among trees can influence lightning–tree interactions, and how lianas can serve as natural lightning rods for trees. Expand
Direct effects of lightning in temperate forests: a review and preliminary survey in a hemlock-hardwood forest of the northern United States
Lightning strikes millions of trees worldwide each year, yet structured lightning damage surveys are relatively rare. Estimates drawn from the literature suggest that lightning directly or indirectlyExpand
Electrical resistivity tomography: patterns in Betula pendula, Fagus sylvatica, Picea abies and Pinus sylvestris.
TLDR
Results demonstrate a high species specificity of ER tomograms and of respective influencing xylem traits and underline the importance of reference measurements for a correct interpretation of ER studies. Expand
Temporal and spatial variation in water content within living tree stems determined by electrical resistivity tomography
Abstract Stem water content (θ) is an important state variable in the soil-plant-atmosphere continuum (SPAC), and varies temporally and spatially in response to environmental factors and plant growthExpand
Evaluation of electrical signals in pine trees in a mediterranean forest ecosystem
TLDR
Electrical signals in a population of Aleppo pines (Pinus halepensis Mill.) in a representative Mediterranean forest ecosystem are analyzed to assess some of the most significant factors that influence the distribution pattern of those electric signals: tree age, measurement type and electrode placement.

Noninvasive Analysis of Tree Stems by Electrical Resistivity Tomography: Unraveling the Effects of Temperature, Water Status, and Electrode Installation
TLDR
It is confirmed that ER tomography of tree stems is sensitive to temperature and water status and suggested that ER analyses may be suitable to nondestructively determinate the hydraulic status of trees. Expand
Tree canopy influences ground level atmospheric electrical and biogeochemical variability
TLDR
It is shown that soil electrochemical properties are tied to temporal dynamics of positive ions in the near-ground level atmosphere, and that the presence of a tree reduces the temporal variability in both ground level positive ions concentrations and soil redox potential, suggesting that a tree can have a stabilizing effect on drivers of temporal variability. Expand
Tree Canopies Influence Ground Level Atmospheric Electrical and Biogeochemical Variability
Static electric fields in the atmosphere are increasingly recognized as interacting with various organisms over several levels of biological organization. Recently, a link between atmosphericExpand
Pantropical geography of lightning-caused disturbance and its implications for tropical forests.
TLDR
Ground and satellite sensors used to quantify the geography of lightning strikes in terrestrial tropical ecosystems indicate that lightning-caused disturbance plays a major and largely unappreciated role in pantropical ecosystem dynamics and global carbon cycling. Expand
The temperature effect and correction models for using electrical resistivity to estimate wood moisture variations
Abstract Electrical resistivity (ER) tomography is a useful nondestructive tool to visualize and estimate moisture content distribution in soil and wood. Wood ER is a function of both moisture andExpand

Cambial and internal electrical resistance of red spruce trees in eight diverse stands in the northeastern United States
TLDR
A comparison of patterns of cambial electrical resistance and of stem internal electrical resistance for eight red spruce stands in the northeastern United States provided a refinement of vigor categories over other comparative methods, and the technique should prove useful for guiding management decisions.

The most significant biotic and abiotic stress agents of water extremity, salinity, and infection lead to wood decay and modifications of moisture and ion content, and density. This stronglyExpand

Sap flow and daily electric potential variations in a tree trunk
TLDR
A comparison of the electrical signals with a direct measurement of the sap flow by a continuous heat flow method shows that the electrical variation, although clearly correlated to sap flow, is not simply proportional to it. Expand
Mechanism relating cambial electrical resistance to periodic growth rate of balsam fir
TLDR
The most probable mechanism relating CER to PGR in balsam fir was variation in the thickness of VCZ and its correlation with potassium content, which released more potassium into the solution contacting electrodes than thinner VCZ of slower growing trees. Expand
Analysis of the willow root system by electrical impedance spectroscopy
TLDR
Electrical impedance spectroscopy was used for hydroponically raised willows (Salix schwerinii) to estimate the root system size and the EIS method proved a useful non-destructive method for assessing root surface area. Expand
