Description:
Abstract:
Mountain pine beetle (Dendroctonus ponderosae, MPB), a bark beetle native to the western North America, has caused vast areas of tree mortality over the last several decades. The majority of this mortality has been in lodgepole pine forests (Pinus contorta) and has heightened concerns over the potential for extreme fire behavior across large landscapes as forest structure and fuels are altered following these MPB epidemics. Although considerable research is emerging concerning the influence of MPB on forest fuels, there has been little work completed previously in the climax lodgepole pine forests of south-central Oregon. Potentially important ecological differences exist as compared to other lodgepole pine systems (e.g. Rocky Mountain lodgepole pine systems). This data publication contains the data collected to assess these differences. Specifically, we measured changes in forest structure and canopy, surface, and ground fuels across a chronosequence of time since mountain pine beetle (TSB) epidemics in south-central Oregon. This data publication contains data collected from 219 randomly located plots representing 19 separate years of mountain pine beetle epidemic initiation during the period 1978-2009. The data were collected during the summers of 2010 and 2011, resulting in a fuels succession chronosequence from 2 to 32 years after a mountain pine beetle epidemic.
Purpose:
The data were collected to assess changes in forest structure, canopy, surface, and ground fuels, and potential fire behavior 2-32 years after mountain pine beetle epidemics in the Deschutes, Fremont, and Winema National Forests in south-central Oregon.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Field measurements were repeated at random by the supervisor on various plots throughout each field season to ensure accuracy of field measurements by all technicians. All measurements are thought to be at least 95% accurate.
Logical_Consistency_Report:
During data collection, data was initially proofed following the completion of each plot. This was done to assure no data points were missing and the data that was collected for certain measures (e.g., % vegetation cover) was logical. If errors were found, data collection was re-checked and corrections were made. Once data was collected, all data was entered by hand into Microsoft Excel spreadsheets. This was done twice by independent data entry technicians. These separate data entries were then cross-referenced in both SAS 9.2, and in Microsoft Excel using separate cross-checking methods. Data entry errors were corrected by referencing original datasheets from the field. Following cross-reference procedures, the distribution of each variable within the dataset were graphed and inspected for outliers or anomalies.
Completeness_Report:
Despite extensive data sheet proofing in the field, individual measurements were occasionally not made. These cases are denoted separately for each attribute in each data file, see the metadata file and descriptions of each data set to locate the missing value identifier for a particular file. In addition, vegetation was occasionally not identified. These cases are indicated in the data file with "Unknown shrub" "Unknown forb" or "Unknown graminoid" as appropriate given the growth form of the unidentified species.

Methodology_Description:
A central fixed area plot (0.025 hectare [ha], 8.92 meter [m] radius) was established for measurement of standing live and dead trees. Within each of these plots, each live tree or snag > 5 centimeters (cm) at breast height (1.37 m) was measured for DBH, which is diameter at breast height (cm) measured at 1.37 m on uphill side, and total height (m) using an Impulse Laser Rangefinder. Species code and status (live = 1 or dead = 2) were also recorded. On all live trees, vigor rating (1 = good, 2 = fair, 3 = poor) and crown class (1 = dominant, 2 = codominant, 3 = intermediate, 4 = suppressed) were also recorded. On live trees, height to live crown base (m) was measured using the Impulse Laser Rangefinder and Dwarf Mistletoe Rating (DMR) was assessed (Hawksworth 1977). On snags, decay class (DC) was assessed on a scale of 1 to 5 (Thomas 1979). For snags with a decay class of 1, a crown status (CS) was assigned (R- red crown, B-brown crown, N-needleless).

Methodology_Description:
The center of each plot was located using a global positioning system (GPS) unit, topographic maps, and compass. Universal Transverse Mercator (UTM) coordinates were provided for each plot center and a waypoint was entered in GPS unit to navigate to plot center. Once within 10 meters (m), distance and bearing specified were measured and plot center was established using rebar. A new GPS waypoint was recorded at plot center after establishment. Plot locations were at least 200 m from any road or disturbance such as fire or clear-cut. If original plot center was within 200 meters of such an area, plot center was relocated at least 200 m in the azimuth away from disturbance or road edge. If plot center is in a riparian area or meadow, plot center was established at least 50 m from the edge of the riparian or meadow habitat. Upon plot establishment, slope, aspect, presence/absence of ladder fuels on the plot were recorded. Photos were taken in the four cardinal directions as well as of the canopy.

Methodology_Description:
Four sub-plots were established 25 meters (m) from plot center in the Northeast (NE), Southwest (SW), Southeast (SE), and Northwest (NW) directions. Starting from rebar at the central TREE plot, the four outer subplots were set up using the Impulse Laser and reflector. All distances for measuring plot radii were slope corrected (i.e., horizontal distance). For subplots a meter tape attached to subplot center stake was used to measure plot radii, keeping tape as level as possible and not following sloped ground surface. Pin flags were used to mark plot edge. Canopy cover was measured using a convex densiometer at each subplot center (as well as at the center of the 0.025 hectare [ha] plot). At each point four readings were taken (each cardinal direction) by rotating around the point in a clockwise position, starting upslope. The number of points on the grid covered by vegetation was counted for each reading. Values fall between 0 for completely open and 17 for completely covered. Within each subplot, seedlings and saplings were measured for height. Seedlings are defined as being less that 1.37 m in height. Saplings are defined as > 1.37 m in height but < 5 centimeters (cm) diameter at breast height (DBH). The center of the seedling/sapling bole at the ground surface must be in the plot to be counted. Tree seedlings and saplings (<5 cm DBH) were tallied by species in 5 cm height classes. Tree seedlings and saplings > 40 cm in height were also measured for Basal Diameter (DBA). DBA was taken using calipers as close to ground surface as possible. In addition, shrub density and height was measured within the subplots. All shrubs were counted and measured for either DBA, canopy L x W x H (length x width x height), or cover. Shrubs requiring basal stem diameter measurements were tallied according to stems of similar diameter. If the base of the stem at ground level is the merging of individual stems into 1 the individual was measured. If multiple stems occur at the ground surface, each stem was individually measured and tallied accordingly. Average maximum height (cm) of each shrub (or shrub clump) was also recorded.

Methodology_Keyword: quadrat cover estimate
Methodology_Description:
At each of the 3.2 meter (m) radius subplots, ground cover was estimated within a 2 x 2 m quadrat. The quadrat was oriented in the direction of the subplot (e.g, NE subplot was oriented in the northeast direction) and such that one corner was centered on the subplot center. Within the quadrat, two technicians estimated percent cover of bare (mineral soil, stone, rock), wood (woody fuel cover), bole (tree and snag bole cover), litter (leaves, needles), vegetation (total vegetation cover under 1.37 m in height), and dead shrub. Bare, wood, bole, litter, and vegetation were equal to 100% when summed. Dead shrub cover was classified separately. For vegetation cover, cover for each species was also estimated separately.

Methodology_Keyword: Brown's transect
Methodology_Keyword: planar line intercept transect
Methodology_Description:
Four 25 meter (m) Brown's transects were installed beginning at the center of the central plot and extending in the cardinal directions (Brown 1982). Along each 25 m transect (starting from outside of the plot to inside), the number of 1-hour, 10-hour, 100-hour, and 1,000 hour fuels were tallied, in addition to measurements of litter (centimeters [cm]), duff (cm), and high particle intercept depth (cm). Fuel classes are defined and measured as:

1-hour - 0-0.64 cm diameter, tallied from 0-2 m along transect;

10-hour - 0.65-2.54 cm diameter, tallied from 0-5 m along transect;

100-hour - 2.55-7.62 cm diameter, tallied from 0-10 m along transect;

1000-hour - > 7.62 cm diameter, tallied and measured (diameter at intersection with transect) along entire transect 0-25 m.

Species was recorded if known. Go-no-Go gauges were used to classify 1, 10, and 100 hour fuels, and diameter measurements of 1,000 hour fuels were done with large metal calipers. Litter, duff, and particle intercept depth were measured at 10 and 20 meters (m) from the end of the transect inward. Additionally, using the first 8.92 m from plot center on each transect, canopy cover was recorded for each individual tree and includes the length of vertically projected canopy cover along the transect tape. The length of intercept (start and stop points) of canopy for all trees > 1.37 m in height was recorded. The layer (O=Overstory, dominant tree crowns, M=Midstory, codominant and intermediate tree crowns, and U=Understory, suppressed tree crowns) was also recorded for each section of transect recorded. If canopy was dead with needles, it was labeled as R or B for Red or Brown.

Methodology_Description:
Photographs were taken at all plots from plot center in the four cardinal directions (north, south, east, west) and an upward canopy photo, before all plots and subplots were measured. From plot center 1 plot scale (i.e., wide angle) photo was taken along each fuel transect. A scale bar and plot identification card were placed in foreground of photo so the entire scale was visible.

Process_Description:
Counts of 1-, 10-, 100-, and 1000-hour fuels (0-0.0.64, 0.65-2.54, 2.55-7.62, and > 7.62 cm, respectively) were converted from counts to megagrams per hectare (Mg/ha) (Harmon and Sexton 1996; Harmon et al. 2008). Seedling/sapling and shrub counts were converted to biomass (Mg/ha) using relationships of height or basal diameter and mass (Brown 1976; Ross and Walstad 1986; Means et al. 1994). Herbaceous cover estimates were converted to tons/acre using equations for the area in BIOPAK software (Means et al. 1994). For species in which no equations were available, mass was estimated based on equations from similar species. Biomass of duff and litter was calculated from depth measurements using conversion factors (Lutes et al. 2006).

Process_Description:
Canopy fuel parameters (canopy base height, canopy bulk density, and canopy height) were calculated using FuelCalc (Heward et al. 2013). Canopy bulk density was calculated using live green trees as well as red (100% needles remaining/recently attacked) and brown trees (> 50% needles remaining). Estimates of foliage retained were based on ocular estimates at the time of sampling. FuelCalc ratios for crown class were used as a proxy for trees with > 50% of needles remaining.

Entity_and_Attribute_Overview:
Filename: DATAFILE_metadata.csv
This is a series of comma-delimited ASCII text files (one for each DATAFILE: canopy, densiometer, fuel_depth, etc.) containing a list of all of the variables in the specified data file along with a description, units, and many other attributes of each variable. Variables included in this dataset:

ATTRIBUTE NAME = Name of variable in data file
DEFINITION = Definition of variable
KEY = Data file is sorted on this variable (Y = yes, N = no)
UNITS = Units of measurement for variable in data file, if Attribute Domain = Range

DATA TYPE = Character, Integer, Numeric, or Date data types, where character = C(character width), i.e. text field that holds up to 10 characters = C10; integer = I(whole number value length), i.e. I5 = integers up to 99999; numeric = fixed precision and scale numbers formatted as Fp.s, where p specifies the maximum number of decimal digits that can be stored, including decimal point and negative signs, and s specifies the maximum number of decimal digits that can be stored to the right of the decimal point, i.e. potential values for F5.2 are 12.03 or -5.29; date = D8 is entered for datetime variables.

NULL = Missing values for variable in data file (Y = yes, N = no)

ATTRIBUTE DOMAIN = One of five domain types which represents the variable: Enumerated: variable with a finite list of codes or values (included in associated DATAFILE_enumeration.csv); Range: variable consisting of a sequence or series of (usually numeric) values between limits; Taxa: variable with a predefined list of taxonomic values from USDA Plants Database (https://plants.usda.gov; lists included in associated DATAFILE_taxa.csv); Place: variable associated with a spatially referenced value (contained in PLOT.csv); Freetext: variable containing values which do not exist in a known or predefined set.

MEASUREMENT SCALE = Measurement descriptors: nominal = variable consists of named categories, coded values; ordinal = variable consists of ordered categories (named categories in set order with reference to one another, but without a distance value between them indicated); interval = variable consists of numeric values with equal sized units on a scale between values (arbitrary starting point, zero value not meaningful); ratio = variable consists of measurements which have a meaningful zero point and ratio comparisons between values are legitimate; datetime = variable consists of date values from the Gregorian calendar

NUMBER TYPE = Most restrictive description of number type for variable in data file (for interval and ratio measurement scales only): whole = only positive integers, including zero; natural = all whole numbers, except zero; integer: all non-fractional positive or negative numbers; real = all numbers that contain fractional or decimal elements.

MIN = Minimum value for variable in data file
MAX = Maximum value for variable in data file
ACCURACY (+/-) = Accuracy of measurement of variable in datafile, if Attribute Domain = Range
PRECISION = Precision of measurement of variable in datafile, if Attribute Domain = Range
MISSING VALUE CODE = Code for missing values for variable in data file, if Null = Y
