Abstract:
Site preparation when applied (hand or mechanical methods) in the western United States often has two objectives: 1) modify the soil, litter, or surface vegetation to create microclimates that favor the establishment and growth of desired tree species and 2) to remove excess surface fuel to decrease the fire hazard. Between 1989 and 1992, data were collected from 11 national forests across the Rocky Mountains (Idaho, Montana, and Arizona) in moist and dry mixed-conifer and ponderosa pine forests. Depending on the forest, stands were treated with the following prescriptions over the five-year period (listed by treatment code): 1 = bole removed followed by broadcast burn, 2 = bole removed followed by dozer or grapple pile, 3 = control (undispersed), 4 = whole tree removal (only in 1990 Helena/Deerlodge Forest), and 9 = burned only. Not every treatment was used in each forest.

Each harvested stand was also paired with an adjacent untreated stand on a similar aspect, slope, and habitat type. For each stand in the study, the variable radius plots were used to collect characteristics on trees > 5 inches diameter at breast height (DBH) and to measure and tally stumps. The information gathered from the variable radius plot included tree species, diameter, and height. Brown’s transects (Brown 1971, 1974) were used to collect data on downed woody debris (dwd) and tree and stump density. The information gathered from the Brown’s transects included size and distribution of the sound and rotten wood currently laying on the ground and estimates of the total weights of sound and rotten wood. These data were intended to provide the general characteristics of live and dead wood for each stand after treatment.

The original intent of the study was to summarize the data to an individual stand so returning to each stand for additional sampling in subsequent years was not planned and plot locations were not permanently marked. However, written or diagrammed descriptions of the location of each sample site exist on the sample forms. These descriptions are included with these archived data in case there is a future need to return to the sample areas.
Purpose:
The overall purpose of this study was to determine how management practices, such as burning, machine piling, scarifying, and scalping, change the character of the organic-rich surface soil layer; and how this change affects seed sprouting, seed-growth performance, and mycorrhizal development that maintain vegetation in these Rocky Mountain forests.

The specific purpose of the tree, stump, and downed woody debris study was to describe whether the growth of trees, and the amount of stumps or dead woody materials varied significantly on a site if it was dozer piled, prescribe burned, or in an unharvested area. Data collection for this portion of the study included measurements on tree and stump size and basal area for all tree species on the plot. It also included measurements in tons per acre of the downed woody debris (fine and coarse), and of the amount of sound and rotten woody debris laying on the ground.
Supplemental_Information:
There are six separate data publications containing the data collected to examine the effect of management activities on forest soil properties in the Rocky Mountains: I. understory vegetation; II. tree, stump, and downed woody debris data (variable plots and transects); III. soil core data; IV. soil chemistry data; V. burn and soil surface conditions; and VI. microsite data.

Description_of_Geographic_Extent:
Study sites were located in Idaho, western Montana, and Arizona. Data were collected from all locations except for downed woody debris data, which were not collected in Arizona. Sample sites in Idaho include the Idaho Panhandle, Payette, Boise, Salmon, Nez Perce, and Targhee National Forests. Sample sites in western Montana include Lolo and Helena/Deerlodge National Forests. Sample sites in Arizona include the Coconino, Apache-Sitgreaves, and North Kaibab National Forests. None of these locations were permanently marked with stakes in any of the sample years. However, instructions were written on each of the field forms for access to the sample locations.

Methodology_Description:
This data publication contains counts of trees, stumps, and downed woody debris collected to determine how mechanical site preparation and prescribed fire affected understory vegetation growth, conifer establishment and growth, and soil physical and chemical properties of some Rocky Mountain national forests. Specifically, these data contain information on the species, diameter, and height of conifer trees and snags, and counts of dead woody debris within fine- and coarse-woody debris classes that were present after silvicultural treatments on each site.

Collecting data and forest information for this study was done using a variety of methods. These methods included a fixed radius plot, a variable radius plot, and linear transects 25 meters (m) long. These data herein include only the information collected using variable-sized plots and linear transects. Variable sized plot measures are based on the idea that every tree size has a different size plot all centered on a point. It relies on the relationship between the diameters at breast height (DBH) of observed trees, the distance between those trees, and the distance to an observer who stands at plot center. The plot extent is usually measured with an angle gauge. Transects are arbitrarily determined lines that trend through a stand. They are employed as a linear form of sample plot and are sometimes referred to as "strip lines."

In this study, the trees and stump information were collected using the variable sized plot on specimens greater than 5 inches in diameter. The tract was measured on a series of points and the trees were tallied for being in or out of the sample area depending on their size and location relevant to the plot center. A prism was used to determine which trees or stumps were within the boundary of the plot and whether to use a Basal Area Factor (BAF) of 20 or 40 square feet per hectare (ft²/ha). The goal was to use a BAF that gave a measure of 4-6 trees per plot. The same BAF was used for all plots within a stand. Each subsequent stand was rechecked for BAF to determine the correct BAF for its particular characteristics. Information on tree and stump species, diameters, and height were all recorded on the variable plot.

The down woody debris data were collected using the linear transects. Ten to twenty five transects were laid out in each stand to collect the dead woody debris data. Each transect was 25 feet long and its trend direction was randomly select using a watch. Each sampler counted the appropriate-sized class of sticks at each interval of the line as divided within the Brown’s transect method (see Brown 1971, 1974). Separate tallies of sticks were made at different lengths along each transect on fine-woody debris 0-0.25 inches, 0.25-1 inches, 1-3 inches, and coarse-woody debris > 3 inches in diameter (see table below). Debris was tallied individually for sound and rotten sticks greater than 3 inches in diameter and for buried debris along the full 25 foot line. The size of the woody debris and the corresponding plane to count within are given below:

Size of debris Length of plane
0.00-0.25 6.0
0.25-1.00 6.0
1.00-3.00 10.0
3.00+ 25.0

Sampling sites for this project were located within a range of habitat types selected in consultation with forest managers, soil scientists, and silviculturists of the Northern, Intermountain, and Southwestern Regions of the U.S. Department of Agriculture Forest Service. The resulting 14 habitat types represented a diverse collection of environmental conditions normally encountered within each of the Regions. The habitat types located within each of the 11 national forests were coded as follows:

Forest Number: National Forest Name, Habitat Types, State
1. Payette, GF/ACGL GF/SPBE AF/VAGL, Idaho
2. Lolo, DF/PHMA AF/XETE GF/XETE, Montana
3. Helena-Deerlodge, DF/CARU AF/VASC AF/LIBO, Montana
4*. Panhandle, WH/CLUN, Idaho
10. Nez Perce, DF/PHMA, Idaho
11. Boise, DF/CARU, Idaho

14. Coconino, PP/QUGA, Arizona
15. Apache-Sitgreaves, PP/FEAR, Arizona
16. Kaibab, PP/FEAR, Arizona
*Forest numbers 5-9 were not included in this study.

Habitat type acronyms descriptions:
AF/LIBO = SAF/LIBO = ABLA/LIBO - Subalpine fir/twinflower (Abies lasiocarpa/Linnaea borealis)
AF/VAGL = SAF/VAGL = ABLA/VAGL - Subalpine fir/huckleberry (Abies lasiocarpa/Vaccinium globulare)

GF/ACGL = ABRG/ACGL - Grand fir/mountain maple (Abies grandis/Acer glabrum)
GF/SPBE = ABRG/SPBE - Grand fir/snowberry (Abies grandis/Spiraea betulifolia)
GF/XETE = ABRG/XETE - Grand fir/beargrass (Abies grandis/Xerophyllum tenax)

For each of the habitat types, a minimum of three stands were randomly selected having similar elevations, slopes, aspects, and treatments, including 1) broadcast burn, (2) dozer; and (3) control (undispersed). Within each stand, a minimum of 12 sites were sampled with the fixed-plot design for tree species. Each site was measured only once unless data became corrupted and there was a need to remeasure in the following year. No special instrumentation was used. Because the intent of the study was not to revisit the sites, GIS locations were not taken for these stands but there is detailed hand-written descriptions of how to get to each site in the sampling records (\Supplements\StandInfo). Similarly, none of the plots sampled with fixed plots were permanently staked to return to for future sampling although there are descriptions of the general area on the plot forms.

To estimate trees and stumps, crews used a 1/300th acre circular fixed plot with a radius of 2.07 m (6.8 ft). Although there were different types of data collected, or samples removed, on each of these plots, the trees and stumps were counted for the entire plot and multiplied to a coverage per unit area.

Criteria for the treatment selections were as follows:
Undisturbed = Mature climax stand, 100+ years old, near a disturbed treatment
Disturbed =
1. Broadcast burn - Typical broadcast burn, within last 10 years, all planted, presence of natural regeneration
2. Dozer - No additional site preparation except for piling, within last 10 years, well planted, presence of natural regeneration


SPECIES CODES

Tree species observed in the fixed-area plots were recorded using designated codes prevalent at sampling time (i.e., 4-codes). The first two letters of the 4-code were from the genus Latin name and the last two letters were from the species Latin name. For example, Pinus ponderosa was coded as (PIPO). These 4-code symbols were first used in the Soil Conservation Service’s National List of Scientific Plant Names (NLSPN), and have been perpetuated in the USDA PLANTS system (http://plants.usda.gov). Trees and snags were counted and recorded separately on each line of the data form. Species, estimated diameter, and height (m) were recorded for trees and stumps less than 12.7 centimeters (5 inches) in diameter at breast height (DBH).

Plot = Plot number. This is an integer value to designate the plot number within each stand. Values are 1-12 per stand and per plot type.

PLT_TY = Plot type. Values are integers designating the following:
1 = Natural trees
2 = Planted trees
3 = Randomly selected trees

Tree_sp = Integers are used to refer to TREE SPECIES in the variable plot data. See \Data\Tree_Species.csv for a description of these codes. NOTE: IF A 9 PRECEDES THE TREE SPECIES, THE TREE IS DEAD

Tree_NUMB = Number of trees from a fixed plot. (See Jain et al. 2021, "Effect of management activities on forest soil properties in the Rocky Mountains: V. Burn and soil surface conditions")

Tree_TPA = Value for trees per acre.

Tree_DBH = Value for diameter of tree in inches. (DBH = diameter at breast height)
If less than 5 feet tall then diameter = basal diameter
If more than 5 feet tall then diameter = breast high diameter

Tree_HT = Value of tree height in feet.

STMP_species = Numerical value for stump species. See \Data\Tree_Species.csv for a description of these codes.

SPA = Value for stumps per acre.

SDBH = Value for the stump diameter at the base in inches.

BAF = Basal area factor. Basal area factor is the number of units of basal area per acre (or per hectare) represented by each tree or stump as measured by a prism. The formula for basal area = (3.1416 x squared DBH)/(4 x 144). This formula simplifies to: basal area = 0.005454 x squared DBH. 0.005454 is called the "foresters constant", which converts inches into square feet. In this study, BAF was measured by a prism to give either 20 square feet/acre or 40 square feet/acre. As you swing the prism around, if it is a 20 it means that for every tree or stump it represents 20 square feet/acre if you have 5 trees it means there is a 100 square feet/acre. We used the same BAF for the entire plot including the trees; so if it is 20 it means we used a 20 BAF prism.

Comments = These are comments for each stand added in the field. Usually they designate a tree as being dead.
