Abstract:
Early in the first part of this century, an initiative was undertaken to investigate the question of the effects of biomass reduction on forested areas. Funding for these investigations was made available through the National Fire Plan (NFP), and President Bush’s Wildfires and Healthy Forest Initiative. Several years later another initiative was instated known as the Biomass Research and Development Initiative (BRDI) which targeted studies involving the utilization of the biomass offsite, for feedstock or other energy needs.

Our BRDI research goals, targeted the soil and water component of the area where the biomass was removed once reduction had taken place These goals examined whether biomass reduction/removal indicated a significant increase in soil erosion, decrease in infiltration or otherwise adversely impact water resources, compared to control sites. To explore these objectives, we installed research sites at several locations and studied management at the small plot scale. The Priest River Experimental Forest (PREF) which is in the northern panhandle of Idaho approximately 12 kilometers (km) (7 miles (mi)) northeast of Priest River, Idaho, was chosen as one research study area because biomass removal projects had been completed in years past. The object of this particular utilization study was to look at the differences between the no canopy clearing of watershed 8 (past research salvaged logged watershed see methodology for more detail) and the nearby canopy covered area that had not been harvested for 100 years.

This data publication contains 2014 data gathered from both the canopy and no canopy areas for ground cover, bulk density, and litter cover. Equipment installed consisted of a 32-point snow course, 12 rain gauges with 24 complementary soil moisture and temperature probes, 2 weather stations and 2 four component net radiation sensors. Data collected from these instruments were gathered during 2014-2017. Daily weather station peripherals included temperature, relative humidity, windspeed, and solar radiation. The four-component net radiation equipment logged (via Campbell Scientific programing) shortwave radiation down and up welling and longwave radiation down and up welling. Additionally, a of raster image of PREF are included, along with shapefiles providing the boundaries of watershed 8 as well as snow course collection point locations, weather stations, rain gauges, soil moisture/temperature probes, and net radiation sensors. Hemispheric photos were collected at the rain gauge locations and next to the net radiation sensors. All hemispheric photos are included in this package.
Purpose:
The object of the utilization study at the PREF was to look at the differences between the no canopy clearing of watershed 8 and the nearby canopy covered area that had not been harvested for 100 years.

BACKGROUND
In 2006, PREF watershed 8 was treated with a simulated fire and in 2007 the remaining timber was utilized by salvage logging. The watershed has a south-southwest aspect (\Supplements\PREF_BU_LocMap.pdf and \Supplements\PREF_BR_LocMap.pdf) and change in elevation from the top of the no canopy area to the end of the canopy sampling point is 120 meters (400 feet) with a cleared area of approximately 4.2 hectares. The utilization study installed monitoring equipment on the burned and salvaged logged watershed 8 because it is relatively free of canopy (see Miller et al. 2021 for further detail). In addition, the wildlife, particularly moose over the intervening years, enjoyed the growth of new fodder and kept the native shrubs trimmed low.

In each area, canopy or no canopy, the following equipment was installed, and data were collected from each:
1 weather station in each area for a total of 2
6 tipping bucket rain gauges in each area for a total of 12
12 soil and temperature moisture probes in each area for a total of 24
16 snow course points in each area for a total of 32
1 net radiation sensor in each type of area near the PREF nursery as electricity was needed, total = 2

Other samples collected:
Bulk density
Cover percent
Litter cover
Hemispheric photos at each rain gauge and net radiation sensor


WEATHER DATA
Two weather stations were installed; one weather station was installed in the middle of the no canopy site of watershed 8 and the other just inside the canopy adjacent to watershed 8 (\Supplements\PREF_BU_LocMap.pdf). Daily weather station data were collected with Campbell Scientific data logger and programs. Connected to the data logger were the following peripherals: wind speed and direction, solar radiation and ambient temperature and humidity. Data were collected from 2014 to 2017.


NET RADIATION SENSORS
Two net radiation sensors were installed. Because of the need for a heating element, this equipment was installed near the PREF tree nursery where electricity was available. One of the net radiation sensors was installed in the canopy near the nursery and the other in the no canopy area next to the acid rain monitoring equipment (\Supplements\PREF_BU_NR_Location.pdf). Daily data are provide for 2014 to 2017.


RAIN GAUGES
Tipping bucket rain gauges were placed at the center cell of a Landsat grid and installed in a back and forth/side-step direction from high to low elevation through the two study areas (\Supplements\PREF_BU_LocMap.pdf and \Supplements\PREF_BU_RG-SMT_Map.pdf). Data were collected from 2014 to 2017 by precipitation event with a time stamp and summed daily.


SNOW DATA
Snow data were sampled at the center cell of a Landsat grid from the top of the watershed to the bottom with the same side-step direction pattern of the rain gauges, and at certain points overlapping with the rain gauge locations (\Supplements\PREF_BU_LocMap.pdf and \Supplements\PREF_BU_SnowPointsMap.pdf). Data were collected from the middle of January to March from 2014 to 2017. Snow data were not extended into March if snow cover was minimal. Collection was performed by following the Natural Resource Conservation Service (NRCS) standards (\Supplements\NRCS_SnowSurveySamplingGuide_AgHandbk196.pdf).


SOIL MOISTURE AND TEMPERATURE
Hobo soil moisture and temperature devices were installed approximately 3 meters east and west of the rain gauge location (\Supplements\ PREF_BU_LocMap.pdf and \Supplements\PREF_BU_RG-SMT_Map.pdf) The data were collected every 30 minutes 24 hours a day and then averaged over the 24 hour period. Soil moisture and soil temperature data from 2014 to 2017 are provided in separate files.


GROUND COVER
Groundcover was randomly measured around each rain gauge from three different points. At each measurement point, a 1 square meter frame with 100 points was placed on the ground and the material beneath the x-sections of the grid recorded (see \Supplements\FieldProcedures_Cover-CE.pdf). Cover classes were mineral soil, ash, rock, branches, organic material, and charcoal. Because no treatment was performed on either the canopy or no canopy sites, cover variability was not a concern, therefore, ground cover was collected only during 2014.


LITTER COVER
Litter cover were collected as outlined by the Forest Inventory and Analysis National Core Field Guide (2011), collecting one sample per rain gauge point location. Once the samples arrived in our lab, the samples were weighed, dried and calculated for total litter cover of the forest floor (\Supplements\LitterCoverLaboratoryProcedures.pdf).


HEMISPHERIC PHOTOS
Hemispheric photos give an in-situ skyward illustration of the canopy at the location of the rain gauge. These photos were taken with a Pentax camera outfitted with a fisheye lens. All hemispheric photos were taken in accordance to the procedures found \Supplements\ HemisphericPhotoFieldProcedure.pdf. The nomenclature for each photo is available in \Supplements\HemisphericPhoto-BU_index-nomenclature.pdf.
