Abstract:
The data set describes post thinning stand conditions of western Oregon Douglas-fir/western hemlock forests ranging in age from 40-70 years old at the time of thinning. Stand characteristics monitored included overstory stand structure and species composition, natural conifer and hardwood tree regeneration and development, species composition and percent cover of understory vascular plants, and the status and recruitment of large and small logs (woody debris) and snags.
The Density Management Study was designed to investigate whether thinning to various densities can accelerate development of late-successional characteristics in young, managed Douglas-fir (Pseudotsuga menziesii) forests (40-70 yrs) while producing wood for the regional economy. The DMS consists of two components: initial thinning treatments (7 sites) and re-thinning treatments (4 sites). These 12 DMS sites are located in the Coast Range and Cascade Foothills of western Oregon. The re-thinning study was installed in 60 to 70-year old stands that were commercially thinned previously. Treatments included a control (once thinned) and a re-thinning treatment to 12-24 trees per hectare (or 30-60 trees per acre), allowing for a clumped distribution. Four treatments implemented at each initial thinning site include an uncut control and units containing one of three levels of residual tree density (high, moderate, and variable density) with circular patch cuts and leave islands of three sizes (0.1, 0.2 and 0.4 hectares or 0.25, 0.5 and 1 acres). The patch cuts and leave islands represent a relatively small proportion of the overall treatment at each site (10% of the treated stand is patch cuts and 10% is leave islands). The initial thinning and rethinning treatments were implemented by thinning from below and by retaining hardwood tree species and minority conifer species. We investigate responses of understory and overstory vegetation to treatments initially after harvest and through time at five year increments following harvests. In addition, we evaluate the relative influence of patch cuts and leave islands on understory vegetation response within initial thinning treatments.

Purpose:
The study was developed to determine if density management of western Oregon conifer forests administered by the Bureau of Land Management could be used to meet late-successional habitat development goals of the Northwest Forest Plan. This study tests new silvicultural systems to determine if they are appropriate management tools for the implementation of the Northwest Forest Plan.
The BLM Density Management Study (DMS) was designed to investigate whether alternative thinnings can accelerate development of late-successional characteristics in managed young forests (40-70 yrs), while permitting timber production at the same time. Such an approach is critical in the Pacific Northwest where a large portion of federal forest lands are young, even-aged conifer plantations. The DMS consists of two components: initial thinning treatments (7 sites) and re-thinning treatments (4 sites). These 12 DMS sites are located on four BLM districts in western Oregon: Salem, Eugene, Roseburg, and Coos Bay. The vegetation study has two main components at this time, both are long-term monitoring studies:


1. Overall treatment effects: Oregon State University is installing new vegetation monitoring plots at each of the initial thinning sites to evaluate overall treatment effects (for objectives, see Vegetation Measurements and Analysis of the Density Management Study Proposal, K. Puettmann 2003). These plots ("treatment plots") are randomly located within the treatments, including gaps and leave islands.

2. Overstory/understory relationships: Permanent vegetation monitoring plots were initially established by the BLM at each site to monitor the relationships of overstory and understory vegetation to target thinning densities (at rethinning and initial thinning sites). These plots ("thinning plots") were only established in thinned forests, excluding gaps and leave islands.

Methodology Description:
Overstory Stand Structure All live trees and snags with dbh >2.0 in. within the 0.25 acre plot were included in the tree survey. Snags were standing dead trees > 4.5 ft tall. Trees were considered "in" the plot boundary if the center of the tree bole at breast height was within the 58.9 ft radius plot. Each tree was tagged at breast height (metal tag facing plot center) with a number unique to the plot. All live and dead tree species were identified. Horizontal distance and azimuth from plot center to each tree bole was recorded. Measurements for each tree followed those in the Table below (Field Protocol DMS Vegetation Study). Live crown ratio (height to live crown is defined as the height at which the crown covers 2/3 of the tree bole, crown class and tree damages and condition were only recorded for live trees. Decay condition and wildlife usage were only recorded for snags.

Understory vegetation (<20 ft tall), seedlings, and saplings were sampled in the 0.005 acre subplots.

Hardwood trees for the BLM monitoring plots were only the species listed in this table.

Estimates of absolute cover for individual plant species and life form groups were made in the 0.005 acre subplots using cover classes: 1 percent = trace, 5 percent, 10 percent, then continuing in 10 percent increments to 100 percent. Species identifications were made following Pojar & Mackinnon (1994) and Hitchcock & Cronquist (1973).
Coarse Woody Debris
Large coarse woody debris was measured along four directional transects, connecting the centers of the 0.005 acre subplots (Cissel, J.H.; Anderson, P.D.; Olson, Deanna; Puettmann, Klaus; Berryman, Shanti; Chan, Samuel; and Thompson, Charley) following the protocol from Harmon and Sexton (1996). Transects were: northeast; southeast; southwest; northwest. Logs positioned parallel to transects were ignored. Small coarse woody debris was measured within the 0.005 acre subplots. All measured logs were > 1 ft in length and were identified to species if possible (see above table 3 for measurements). Logs at > 45 degree angles above the ground were not considered down woody debris (pers. com. M. Harmon).

Stumps
All stumps in the northeast quarter section of the 0.25 acre plot (or straddling the boundaries) were measured (Cissel, J.H.; Anderson, P.D.; Olson, Deanna; Puettmann, Klaus; Berryman, Shanti; Chan, Samuel; and Thompson, Charley.). Stumps were < 4.5 ft tall (measured on the up-hill side) and > 2 in at the point of separation. Stumps were either new man-made stumps from harvest, remnant stumps from before harvest, or natural stumps from blow down. Stumps were identified to species if possible and measured for diameter and height.

Substrate
Estimates of absolute cover for substrate groups were made using cover classes: 1 percent = trace, 5 percent, 10 percent, then continuing in 10 percent increments to 100 percent.

Methodology Description:
Overstory Stand Structure All live trees with dbh >2.0 in within the 0.25 acre plot (58.9 ft radius) were included in the tree survey. All snags (standing dead trees > 4.5 ft tall; and remnant stumps (old stumps from before the initial thin 10.0 in dbh and 1 ft tall) within the 0.25 acre plot were also included in the survey. Remnant stumps were not recorded at the Bottomline site, but the protocol was amended and crews began sampling remnant stumps at all other sites.

Trees were considered "in" the plot boundary, if the center of the tree bole at breast height was within the 0.25 acre plot. Each tree was tagged at the base (metal tag facing plot center) with a unique number. All live and dead tree species were identified. Distance and azimuth from plot center to each tree bole was recorded. Measurements for each tree followed those in table 3 below. Live crown ratio, crown class and tree damages and condition were only recorded for live trees. Decay condition and wildlife usage were recorded only for snags.
One Douglas-fir tree per plot was selected arbitrarily (usually the largest tree on the plot, maximum dbh of 30 in) as the site tree. In addition to measurements listed in table 3, height, live crown height, age at breast height (years), and growth increments at 5 and 10 years (1/20 in) were measured for the site tree. In many cases, the site tree was the plot center tree.

The clump data were not consistently collected across sites and sometimes the method of collection varied within sites. Therefore, subsequent visits to the sites will not include remeasurements of clumps. However, the tagged trees > 2 in. in the clumps are included in the overstory tree data and will be remeasured upon future visits. These trees > 2 in. in the clump will receive a CL in the remarks section, indicating that it is a tree part of a hardwood clump. Clump data are stored in Excel spreadsheets, but are not included in the DMS vegetation database.
Understory Vegetation
Understory vegetation, seedlings and saplings were sampled in the 0.005 acre subplots. See following table from Field Protocol DMS Vegetation Study.

Conifer seedlings and saplings were always tallied, however, hardwood seedlings and saplings were not consistently recorded at each site, but will be measured in the future..
Estimates of absolute cover for individual plant species (no height limit) and life form groups were made in the 0.005 acre plots. Plant identifications for all plots followed Hitchcock & Cronquist (1994), Pojar & Mackinnon (1994) and the Jepson Manual (Hickman 1993). Cornus nuttallii, Prunus emarginata, Rhamnus purshiana, Salix spp., Lithocarpus spp. and Malus fusca were originally considered hardwood trees in 1997 measurements (Bottomline, OM Hubbard, Keel Mountain and Sand Creek sites). These species were later considered understory shrubs in subsequent site measurements and consequently, were edited out of the overstory data sets for Bottomline, OM Hubbard, Keel Mountain and Sand Creek for consistency with the revised sample method.

Presence of vascular plant species associated with late-successional/old-growth forests (FEMAT species;USDA and USDI 1993) was recorded for the 0.25 acre plot and exotic species will be recorded in the future. The species monitoring was included in the study to specifically evaluate the effects of this treatment on late-successional species.
Coarse Woody Debris
All large coarse woody debris logs were measured in the 0.25 acre plot. Small coarse woody debris was measured within the 0.005 acre subplots. All logs > 1 ft in length were measured and identified to species (see table 3).
Stumps
All newly cut stumps (from the harvest) in the 0.25 acre plot were tallied in 2 inch diameter classes. Stumps were < 1 ft tall (no minimum diameter cut-off). At rethin sites, both stumps from the initial thin and rethin (that is, new and old stumps) were counted. Stumps were identified to species if possible. Stumps were considered in the 0.25 acre plot if the center of the stump was within the plot boundary.

Measurement Schedule
Remeasurements of both treatment and thinning plots are scheduled in five-year increments (see measurement schedule, tables 12 and 13, p 47). Coarse woody debris and stumps are being remeasured every 10 years since they change slowly in the forest. Evaluation of the current data and future follow-up treatments may result in some modifications in the future remeasurement schedule at the thinning study vegetation plots.

Data Management
Data is either entered directly into a computerized format using electronic polycorders, RECON datalogger units or palm pilots in the field, or recorded on paper data sheets. Electronic polycorder data collectors use error-checking routines built into the data collection system to catch invalid or missing data while the crews are still on the plot. Spread CE program is used for data entry in the RECON units and data validation options are enforced for the attributes to reduce field error. Data entered on data sheets are proofed in the field and later entered into a spreadsheet and crosschecked for data entry errors.

All data sets are quality checked for errors by conducting summary statistical analysis and by graphing the results (following standard data-cleanup procedures). Erroneous data are field verified and corrected or flagged in the data set (that is, when data are clearly incorrect). Clean data will then be imported into the DMS vegetation database.

All clean data are in Microsoft Excel spreadsheets and in an Access database that is still undergoing development. Excel spreadsheets of the raw data are retained. All data are currently stored on the Oregon State University server, which is backed up off site every night. The vegetation data ultimately will be stored in the Oregon State University Forest Science Data Bank.

A data management protocol has been developed to maintain consistency and quality control for data collected and entered into the database each year. A metadata specialist with the National Biological Information Infrastructure (NBII; http://www.nbii.gov) has developed the project metadata following NBII standards. Metadata will be updated on a yearly basis. In addition, The Northwest Alliance for Computational Science and Engineering, a partner with NBII, is assisting with the development of the DMS vegetation database.

Analysis
Data analyses will assess initial vegetation response to the thinning treatments within the first years following harvest (thinning plot data: one to three years;treatment plot data: six years). Subsequent analyses will evaluate changes in vegetation response over time (using repeated measurements taken at five-year increments). The analysis approaches will follow a randomized block design, where treatments were replicated across sites (that is, blocks = sites; seven blocks in the Initial Thinning Study; four blocks in the Rethinning Study). Treatment averages will be calculated to evaluate differences in overstory and understory vegetation dynamics and conditions in the thinning treatments (that is, the treatment plots including gaps and leave islands) and in homogenous thinning conditions (that is, the thinning plots, only where target densities were achieved).

Analyses will evaluate effects of thinning on various aspects of overstory and understory vegetation structure and composition. Pre-harvest data are not available for these sites; therefore, all thinning treatments will be compared to the unthinned controls to evaluate treatment effects. Analysis of variance (ANOVA) and multiple comparison tests (that is, pre-determined contrasts: thinned versus unthinned; and contrasts comparing thinned treatments) will be used to assess differences in vegetation responses among treatments. Sites are random effects and treatments are fixed effects in the ANOVA analyses. When evaluating thinning effects on vegetation dynamics over time, initial overstory conditions (from the first measurement date) will be used as covariates in the ANOVA models. All ANOVA statistical procedures will be performed using SAS (SAS Institute Inc. 2001).
Overstory
All evaluations of treatment effects for overstory vegetation will be made using ANOVA. Overstory tree growth (average tree growth and growth per hectare) will be compared among thinning treatments (for selected species where degrees of freedom > 20). Differences in growth of dominant trees (for example, 10 or 20 largest trees/ha) will also be compared among treatments to determine if the DMS thinning treatments are accelerating large tree development. Crown development of overstory trees will be compared among treatments using average crown ratio or percent live crown of selected species where degrees of freedom > 20.

Understory
Treatment averages will be calculated for understory vegetation cover, variability (coefficient of variation for mean cover) and frequency for life form groups, seral groups and exotic species. ANOVA and multiple comparison tests (described above) will be used to determine differences in understory vegetation cover among the thinning treatments.

Patterns of community composition within and among sites will be evaluated using non-metric multidimensional scaling (NMS; Kruskal 1964; Mather 1976) ordination and will be related to stand and site characteristics (for example, physiography, overstory structural characteristics, initial site condition factors, seedling and sapling density, and harvest disturbance factors) and treatments (thinning treatments and sub-treatments, gaps and leave islands). Multiple response parametric procedure (MRPP; Berry et al. 1983; Mielke 1984) and indicator species analysis (ISA; Dufrêne and Legendre 1997) will be used to determine potential differences in understory communities among treatments and to identify indicator species driving these differences. Evaluation will be made on how sub-treatments (gaps and leave islands) contribute to overall treatment variation in understory vegetation communities using NMS ordination, MRPP and ISA analyses. Frequency distributions of species in the gaps, leave islands and forest matrix areas will also be evaluated. NMS ordination, MRPP and ISA analyses will be performed using PCORD (McCune and Mefford 1999).

Plant communities will be analyzed in the riparian and upslope locations for the thinning plots to help assess the impact of less intensive sampling schemes for the thinning plots (that is, possibly reducing sample size for 0.25 acre Thinning Study vegetation plots, or dropping some riparian reserve plots).

Summaries of coarse woody debris (large and small) will be made at the treatment level for all sites and will be monitored through time. We will determine if the amount and characteristics of the coarse woody debris meet the late-successional objectives of the DMS.

Methodology Keyword: DMS site selection

Methodology Description:
Study sites were initially intended to be broadly representative of forest lands managed by the BLM in western Oregon, and to include sites in the Cascade, Coast, and Klamath provinces. A decision was made to focus first in the Cascade province because it was believed that implementation would be less complex in the Cascades. Site selection began in 1993 and was completed in 1995. Eventually, BLM silviculturists and Dr. Tappenier realized that the study design was not feasible for the Klamath province and a decision was made to drop further consideration of the Klamath province as potential DMS sites in 1996. The high heterogeneity of forest stands in southern Oregon, and site conditions that were significantly different from other study sites in the Cascade and Coast provinces, led to this decision. This decision resulted in twelve study sites broadly representative of mesic, low-elevation forests in the Cascade and Coast provinces of western Oregon (table 1). Each west-side BLM district was provided site selection criteria for the Initial Thinning Study and asked to screen their upcoming thinning sales for potential study sites. Although there were minor changes over time, the criteria attached to the March 29, 1994 BLM State Office directive (Appendix B) were widely used for site selection:
1.Prefer sites that are in the General Forest and Connectivity land allocations in the BLM resource management plans
2.Stands should be between 30-50 years old
3.Sites should be at least 200 acres in size and capable of subdivision into four 50 or more acre units
4.Stand conditions should be relatively homogeneous
5.Avoid Tier One Key Watersheds and watersheds where watershed analysis has not been completed
6.Presence of streams is a positive factor since streams are necessary to implement the Riparian Buffer Study
7.Avoid stands that have experienced or are likely to experience significant wind damage
8.Avoid stands with extensive root disease

Criteria used for the Rethinning Study were similar, but tailored to the Rethinning Study design:

1. Prefer sites that are in the General Forest and Connectivity land allocations in the BLM resource management plans
2. Stands should be between 50-80 years old and previously thinned
3. Sites should be at least 40 acres in size and capable of subdivision

into two, 20 or more acre units
4. Stand conditions should be relatively homogeneous
5. Avoid Tier One Key Watersheds and watersheds where watershed analysis has not been completed
6. Avoid stands that have experienced or are likely to experience significant wind damage
7. Avoid stands with extensive root disease

Resource specialists identified candidate study sites, evaluated sites based on the criteria above, ranked sites considering all criteria, and selected study sites in consultation with Dr. John Tappeiner, study PI; Charley Thompson, study coordinator; and local decision-makers.

Seven sites host a full set of DMS initial thinning treatments (three in the BLM Salem District, two in the BLM Eugene District, and one each in the BLM Roseburg and BLM Coos Bay Districts; fig. 3). Rethinning treatments are located on four sites (one each in Eugene, Roseburg, Salem, and Coos Bay Districts; fig. 3). Site location and summary information is contained in fig. 3 and table 1; detailed site histories are in Appendix 4.

Study Sites
Vegetation plots are established at seven of the initial thinning sites and all five sites subjected to rethinning treatments. Two initial thinning sites (Keel Mountain and Delph Creek) are in the foothills of the Cascades, while all other sites are in the Oregon Coast Range. No consistent set of detailed vegetation data were collected prior to treatments. Pre-treatment data was collected at the Ward Creek rethinning site near Roseburg, OR.

Sampling Design
Vegetation response to the thinning treatments is characterized by repeated sampling of the treatments at all sites. The sites are treated as replicates (or blocks) in the study. The sampling design varies for the two components of the vegetation study: "treatment plots" and "thinning plots". These two component studies were initiated at different times and have different research objectives (see above). Consequently, the sampling protocols and plot layout vary for these two components (see details in Sampling Methods and Sampling Protocol; http://ocid.nacse.org/nbii/density/). To minimize impact of measurements, for both studies the understory vegetation is measured during the summer month, followed by the tree measurement. Special care is taken to avoid contamination of study sites from introduction of propagules by the field crew.
