Methods and protocols used in the collection of this data package
Description:

Sap flux density probes were installed in three trees of low, medium, and high visual effects of BLD and run from August 12, 2021 to August 27, 2021.

Description:

Sap flux probes used the Granier constant heat dissipation method (Čermák et al 1973), which involves embedding a T-Type thermocouple into two hypodermic needles that are inserted into the xylem.

Description:

One of the needles has a heating wire wrapped around it, serving as the heat source for the measurement of heat dissipation.

Description:

The needles were inserted into a 31 mm deep pre-drilled hole at breast height, approximately 1.4 m above the soil surface.

Description:

The heated probe was inserted in a hole located 10 cm directly above the reference probe.

Description:

After insertion of the probes, silicone caulk was applied to seal off any gaps that could be left from the hole so as to prevent heat escape.

Description:

Mylar wrap was stapled onto the trees around the probe to prevent solar radiation from affecting the measurements.

Description:

The probes were logged every 30 seconds with the Mayfly data logger, an Arduino-based microprocessor and data logging components.

Abstract:

The spread of Beech Leaf Disease (BLD) is affecting forests across eastern North America. We studied how BLD is impacting forest hydrology of an impacted American Beech stand. We used a decade of microclimate monitoring in an American Beech stand to assess how BLD alters air temperature, humidity, solar radiation, and soil moisture. We also conducted short-term monitoring of sap flux density in three trees of varying BLD impact. We identified trends of increasing solar radiation and soil moisture as the forest stand experienced an increasing effect of BLD. We found that the sap flux density in the tree most affected by BLD was 20% lower than less impacted trees. The results are consistent with past studies that demonstrated how forest pests and pathogens reduce transpiration and increase soil moisture.
