    50 Years at the Cloquet Forest Research Center
    (1960) Schantz-Hansen, Thorvald
    This is the story of the first fifty years (1909-1959) of the Cloquet Forest Research Center (now the Cloquet Forestry Center), as recorded by T. Schantz-Hansen circa 1960 in 31 typed pages. It summarizes the events and personnel involved with establishing the Center, early research and management activities on the forest, the nursery program, and personnel involved over the years, including lists of superintendents, foremen, student workers. The narrative includes many mentions of forest fire, the causes of fire, which was most often railroads, berry pickers, or picnickers, and the work that was done to create fire-lines for suppression and prevention efforts. The October 12, 1918 Cloquet fire is specifically mentioned as having not impacted the lands. It also summarizes the work conducted at the Center by the Civilian Conservation Corps (CCC). The origins of this document and if it was ever published are not totally clear. Even so, it provides the most succinct narrative of the history of the first 50 years. The author started work at the Center in 1919 and served as the lead administrator from 1923-1960. Two paper copies of this text have existed in the Forest Manager's file cabinets over the years. This is intended to be a digital archive of the paper copy that is thought to be the most complete version. It was scanned on July 17, 2020.

    Analysis of the Cloquet Forestry Center continuous forest inventory 1959-1990.
    (University of Minnesota, 1994-12) Tuhus, Erik H.; Walters, David K.; Ek, Alan R.
    This report describes procedures, analysis, and results from a study of the Cloquet Forestry Center continuous forest inventory (CFI). The CFI on the property was established in 1959 and plots have since been measured five additional times. Summary tables are presented for individual covertypes and for covertype aggregates, for all measurement years. Trends in covertype acreage, growing stock, age class, and size class distribution for the forest over the 31-year period are also discussed. This study was conducted using an Rbase 4.5 relational database on a PC. A description of Rbase command files developed and used in the study and necessary editing and changes made to the database are included as appendices.

    Assessment of the growth and yield potential of the Cloquet Forest with a computer-based growth projection model
    (University of Minnesota, 1980-12-01) Moeur, Melinda; Ek, Alan R.; Rose, Dietmar
    A comprehensive data base consisting of permanent plot information from four survey years (1959 to 1976) was compiled for the Cloquet Forestry Center. Corresponding covertype data was developed and covertype maps were drafted. A distance-independent individual-tree-based growth model (MFPS) was used to project growth and yield for covertypes, with and without management. Management projections involved harvest by clearcut and subsequent regeneraton. Covertype summary table of initial inventories and projection results were produced by SUMREP, a computer program containing whole-tree biomass and product volume functions. Potential income from predicted first decade harvest of the red pine covertype is presented.

    Cloquet Forestry Center automated weather station data for calendar year 2019
    (2020-09-23) University of Minnesota Cloquet Forestry Center; kggill@umn.edu; Gill, Kyle G; University of Minnesota Cloquet Forestry Center Forest Management and Research
    Weather station data for calendar year 2019 from the University of Minnesota Cloquet Forestry Center automated weather station as collected by a Campbell Scientific CR1000 datalogger and various sensors. The automated weather station serves as a higher resolution dataset and backup for the manually-collected daily weather observations that are recorded and submitted to the National Weather Service. It also includes data from sensors not required by the NWS. Data for this dataset are collected by each sensor every 20 seconds and aggregated and recorded at the CR1000 in five minute intervals. They were downloaded and appended to the growing dataset manually by CFC staff weekly. The Direct Weather Download Protocol by CFC staff is followed to ensure datalogger data quality control steps are in place during manual data download, transfer, and archiving.

    Cloquet Forestry Center Research Papers and Reports 1912-2011
    (Minnesota Agricultural Experiment Station, 2012) Severs, Ronald; Alm, Alvin A; Olson, Rylie
    This listing is an update of a listing published by Avin Alm in 1988 titled: Cloquet Forestry Center Papers and Reports for the 75-Year Period From 1912-1987. This paper provides a listing of reports, theses, and journal articles covering work conducted or materials and services provide at the University of Minnesota, College of Food Agricultural and Natural Resource Sciences, Cloquet Forestry Center. The listing covers the period from 1912-2011. A total of 903 papers are listed. Although considerable effort was made to make the list as complete as possible it may be that there are some omissions. Hopefully, readers of the list will assist in providing any additional citations that can be in a future update. The listing is divided into two sections. Section I is in alphabetical sequence by authors last name. Section II provides a cross reference by subject matter with citation numbers referring to the Section I alphabetical listing. The compilation of early research publications related to the Cloquet Forestry Center is the result of the wisdom of early Directors who saw the value of documenting research activity of the time. A chronological listing from 1912 to 1960 was complied by Dr. Bruce A. Brown, Cloquet Forestry Center Director from 1960-1974 and additional compilations by Dr. Al Hallgren, Cloquet Forestry Center Director from 1975-1987. Their efforts are acknowledged as well as the help and assistance of the various University of Minnesota faculty and staff whom provided additional listings. Since 1947 funding for supporting long term research at the Cloquet Forestry Center has been provided in part by MAES Project No. MIN-40-015: Dynamics, Management and Sustainable Use of Northern Forest Ecosystems.

    Continuous Forest Inventory Plots for the UMN Cloquet Forestry Center
    (2020-07-30) UMN Cloquet Forestry Center; UMN Department of Forest Resources; lbj@umn.edu; Johnson, Lane; University of Minnesota Experimental Forests; University of Minnnesota, Department of Forest Resources, Interagency Information Cooperative; University of Minnesota Cloquet Forestry Center
    The University of Minnesota Cloquet Forestry Center is a field research and instructional station associated with the College of Food, Agricultural, and Natural Resources Sciences (CFANS). Continuous Forest Inventory data has been collected for the CFC since 1959. The network of permanent forest measurement plots consists of 406 1/7 acre plots with a subset of these plots re-measured up to seven times since establishment. The last re-measurement occurred Summer 2014. The majority of the CFI plots were geolocated with a Trimble GeoXT GNSS receiver in 2014 or 2015 to obtain sub-meter precision for each plot center. Plot locations are marked in the field with a tagged center post with painted tree numbers oriented to plot center. Eight plots without precision GNSS locations are indicated within the attribute table. One plot location is missing from this dataset as it could not be relocated in the field (Plot_ID = '620'). The most recent report on the UMN Cloquet Forestry Center CFI is available as 2016 Staff Paper No. 243 published through the UMN Department of Forest Resources and summarizes findings from the 2014 remeasurement.

    Experimental Forests project proposal and record form metadata
    (2022-01) Gill, Kyle G
    The UMN Experimental Forests research coordinator uses a project tracking procedure, often called the Project Records data management system, to document and record the research, teaching, demonstration, management, and other activities that occur across the land base. The goal for tracking is to be a good steward of the land and data resources by documenting the extent to which we are manipulating, using, and observing the ecosystems. To initiate a project, potential project leaders submit a Project Proposal Form. Once a project is approved, the project is given a unique ID number and the form becomes the project's Project Record form. This metadata document describes the information/data that is recorded in each section of the proposal/record form. It is intended to both help answer questions as project leaders fill out the form and to serve as metadata for the Experimental Forests research coordination team.

    History of the Cloquet Forest Experiment Station
    (1917) Kenety, W H
    A draft forest management report thought to have been completed in the winter of 1916-17 by W.H. Kenety, Superintendent of the Cloquet Forest Experiment Station with support from G. H. Wiggin, Assistant Forester at Cloquet. The report details station operations beginning in 1910 with detailed information on nursery work and early reforestation efforts. Other subject matter includes land acquisition history, existing infrastructure, staffing, land types, vegetation types, methods for tree seed collection, arboretum plantings, experimental tree plantings, meteorological observations, and soil conditions. Photograph prints are included to illustrate forest conditions, early nursery operations, station improvements, and research projects. An abbreviated version of this 354 page report was published October 1917 by the University of Minnesota Agricultural Experiment Station titled: "Report of the Cloquet Forest Experiment Station". A digitized version of the published 1917 report can be found online through Google Books.

    Impacts of the July 2016 windstorm on the UMN Cloquet Forestry Center forest
    (2024-01) Gill, Kyle G
    A windstorm blew through northern Minnesota on July 21, 2016. Varying levels of impacts to forests were observed across the region. This report outlines the methods and results of a windstorm impacts assessment for the University of Minnesota Cloquet Forestry Center forest. Windstorm impacts were assessed on total of 246 continuous inventory plots and the traverses between plots for both monitoring reasons and to assess whether or not salvage logging operations were needed. Plot-based results showed that 86.6% of the forest had no impacts, 12.2% had low impacts, and 1.2% had high impacts. Traverse-based results, which were more sensitive, suggested that up to 34% of the forest may have had low impacts. Lowland forest cover types were slightly more likely to have been impacted than upland cover types. No salvage operations were deemed necessary based upon these results.

    Investigating red pine and white spruce growth dynamics in microplots: three-year results
    (2021-04) Russell, Matthew; Gill, Kyle G
    Miniature scale or “microplots” can be used in forest experiments to speed up the time period needed to understand forest dynamics. This reports analyses three years of red pine and white spruce growth in microplots located at the Cloquet Forestry Center, Cloquet, MN. Spacing of the microplots and species mixture did not influence the relative height and groundline diameter growth trees in the microplots after three years. Future work will continue to monitor these trees through annual measurements and a destructive sampling effort will inform biomass partitioning patterns that can be compared to operational scale plantings.
