Item Assessing the financial effects associated with implementing Minnesota's timber harvesting and forest management guidelines.(University of Minnesota, 2000-09) Blinn, Charles R.; Taff, Steven J.; Thompson, Michael J.; Mlinar, Marsha; Townsend, NeilItem DTRAN version 1.0 : a multi-market timber supply model : user's guide.(University of Minnesota, 1991-07) Hoganson, Howard M.; Kapple, Douglas C.Item DTREES : a Decision Tree System for developing harvest schedule prescriptions : user's manual.(University of Minnesota, 1989-05) Pelkki, Matthew H.; Rose, DietmarItem DUALPLAN version 1.0 : a stand management scheduling system : user's manual.(University of Minnesota, 1989-10) Hoganson, Howard M.; Rose, DietmarItem Educational needs assessment of tree and woodland programs in Minnesota: results from a 2020 study(2021-02) University of Minnesota Extension ForestryThe interests of current and potential participants are essential in determining which educational programs are offered by outreach and Extension organizations. In October 2020, the University of Minnesota Extension Forestry team gathered responses to an educational program needs assessment survey, receiving a total of 314 respondents. The most popular topics identified in the survey were woodland management, wildlife, and tree and plant identification. Not surprisingly, respondents preferred virtual learning formats during the COVID-19 pandemic. When asked about learning preferences after COVID-19 pandemic ends, the most preferred class format was a field day. These findings will inform future tree and woodland educational programs in Minnesota. The survey also revealed opportunities for new programs focused around topics such as managing woodlands for wildlife, the history of Minnesota forests, and the impacts of climate change to Minnesota forests.Item An evaluation of the native plant communities management guide for mesic and dry-mesic white-red pine in Northern Minnesota.(University of Minnesota, 2002-03)A guide was developed to provide management information on native plant communities, specifically mesic and dry-mesic white-red pine in Northern Minnesota. This guide was reviewed by many professional foresters (planners, field personnel, and researchers). A survey was mailed to 110 people involved in forest planning and management in Minnesota to evaluate how well the concepts in the guide were understood and how feasible it would be to implement the recommendations. The return rate for the survey was 52%. The overall understanding of the native plant community concepts presented within the guide was relatively high. However, the feasibility to implement the landscape and site-level recommendations presented was only “somewhat”. Many impediments to implementation were identified. Some of the most referenced included: lack of time, lack of money, and lack of professional staff. After a review of the surveys, the management guide was revised to address specific comments provided by survey respondents. Additional references to available classification keys were added along with discussion on impediments in the management recommendations. Overall, the guide was successful in communicating native plant community information to the diversity of people involved in forest management. There is likely a need for similar guides, and more audiencespecific guides and training in the future.Item Forest planning review.(University of Minnesota, 1989-10) Rose, Dietmar; Hoganson, Howard M.Item GISTRAN version 1.0 : a geographic information system for modelling forest products transportation : user's guide.(University of Minnesota, 1991-09) Kapple, Douglas C.; Hoganson, Howard M.Item Hydronomic Analysis of Forest Management Alternatives for Environmental Quality: A Case Study of Itasca County(Water Resources Research Center, University of Minnesota, 1975-08) Clausen, John C.; Mace, Arnett C.; O'Hayre, Arthur P.The objective of this investigation was to develop a methodology that integrates water use and environmental quality parameters into an economic system to evaluate forest management alternatives. The input-output technique was the general methodology used for integrating water use. Direct and direct-plus-indirect water use coefficients (total withdrawn and consumptive) were determined for each of the 34 economic sectors in Itasca County, Minnesota. An example was developed from the harvesting alternatives of clearcutting, strip cuts, and selection cuts. A zero water use coefficient was used for timber production, under water surplus conditions, and the water required was 44 million gallons. This value was low in relation to the increased water yield. Under assumed water scarcity situations, the water use coefficient was 175,560 gallons/dollar of output for timber production, and the water required became 16.2 billion gallons which was much greater than the increased water yield.Item Keep Your Woods Healthy for Tomorrow: A Tool to Assess Risk in Minnesota's Changing Climate(University of Minnesota Extension, 2020) University of Minnesota ExtensionMaintaining a healthy woodland is getting harder and harder. In today’s world, there are an increasing number of stresses on woodlands, including climate change. This document is for private woodland owners in Minnesota interested in assessing risk and adapting their properties to climate change.Item Managing Ash Woodlands: Recommendations for Minnesota Woodland Owners(University of Minnesota Extension, 2019) University of Minnesota ExtensionThis document provides ash management recommendations for private woodland owners in Minnesota. After the emerald ash borer (EAB) was found in Minnesota in 2009, the University of Minnesota Extension and the MN Department of Natural Resources (DNR) quickly recognized the need to offer practical and timely ash management recommendations for woodland owners. This document synthesizes expert woodland recommendations presented in previous publications in addition to scientific results from on-the-ground research studies.Item Managing public forests in a shared-power world : the integration of conflict management principles into USDA-Forest Service planning and management.(University of Minnesota, 1993-09) Cheng, Antony S.; Anderson White, T.; Hacker, Jan J.; Ellefson, Paul V.Item Minnesota Timber Harvesting GEIS : an assessment of the first 10 years.(University of Minnesota, 2005-08) Kilgore, Michael A.; Ek, Alan R.; Buhr, Karen A.; Frelich, Lee E.; Hanowski, JoAnn M.; Hibbard, Calder M.; Finley, Andrew O.; Rathbun, Leah; Danz, Nicholas P.; Lind, James W.; Niemi, Gerald J.Item MORPHOLOGICAL, PHENOLOGICAL, AND TRANSPIRATIONAL DIFFERENTIATION IN POPULATIONS OF QUERCUS MACROCARPA AND QUERCUS RUBRA(2024-05) Bergen, ErinThe characteristics and consequences of climate change are unfolding with unprecedented speed worldwide, and few places are changing faster than northern Minnesota. This study takes a unique approach to quantifying arboreal variation in physical plant traits and plant water use in the context of climate change. Two populations, northern and southern, of two species, Quercus macrocarpa and Quercus rubra, were grown in a common garden experiment at a northern field site and compared for climatic suitability. Traits that are known to have adaptive value, such as growth, leaf attributes, and phenological traits, were measured and compared. In addition, the transpiration rates of these populations were captured via portable rapid evapotranspiration chamber for comparison. Trees in a forested watershed can be responsible for up to 70% of the ecosystem’s water loss. Population-level differentiation in transpiration has ramifications for water cycling and may be an important but understudied consideration in climate-forward forest management practices. Rather than struggling in an adverse environment, these two species maintained their cohorts well, indicating that climate shifts have created hospitable long-term conditions for these species. There was genetic differentiation between the two populations for each species for traits that are important for climate adaptation. These differences were especially strong for fall phenology traits and notable for physiological traits linked to water use adaptation, such as specific leaf area. Importantly, measured transpiration varied at a population level for both species. In late August 2020 and 2021, Q. macrocarpa populations significantly differed in their transpiration rate and therefore water use. Furthermore, in a year with more water stress, Q. rubra also demonstrated significant population differentiation in midsummer transpiration. This suggests true population differences, a pattern that may become more evident over time or if additional sites from the original experiment are measured. A model constructed using field precipitation, discharge, and transpiration measurements demonstrated that each population for each species would have a unique impact on the discharge of the Stewart River. This study is one of the known few to demonstrate population differentiation in tree transpiration rates, particularly in Q. macrocarpa and Q. rubra. Taken altogether, this study demonstrates that northern populations may be falling out of alignment with local climate, at the cost of lost growth opportunities and greater winter stresses at the margins of the growing season, and that tree cover can have distinct impacts on ecosystem water balances even at a population scale. This presents an opportunity to counteract the desynchronization of climate shifts with local adaptations, especially in heavily forested regions such as northern Minnesota, and highlights the need for further investigation of water use impacts of trees chosen for planting.Item Perspectives on Ash Wood Utilization and Marketing in Minnesota(2020-08-31) Russell, Matthew B; Ring, Elizabeth C; russellm@umn.edu; Russell, Matthew B; University of Minnesota Department of Forest ResourcesIn 2019 the University of Minnesota surveyed forest products companies and natural resource managers about the use of ash wood and the future of the ash resource in Minnesota given the current and future distribution of the emerald ash borer. The survey was used to gain knowledge on the current and future use of ash wood in Minnesota. This information has provided information to researchers and managers on current and future approaches to utilize forest products from ash trees.Item Spatio-temporal Ecology of Forest Birds(2015-05) Grinde, AlexisMaintaining avian diversity in forest ecosystems have been shown to afford many benefits for forest health and productivity. However, alterations to the historical disturbance regimes within hemiboreal forests have impacted bird communities, and the ability of landscapes to meet the ecological needs of breeding forest birds has become a growing concern. As changes in forest landscapes continue, landscape effects may become increasingly important drivers of population dynamics for forest bird species. This dissertation includes a combination of experimental, theoretical, and applied research to assess the influence of habitat, landscape, community composition, and life history traits on population dynamics of forest birds. This research aids in identifying mechanisms associated with species population dynamics which is critical for understanding long term population trends and factors that contribute to species persistence and maintenance of biodiversity.Item State government agencies and authorities affecting the use and management of forests in northern United States.(University of Minnesota, 2005-05) Ellefson, Paul V.; Kilgore, Michael A.State agencies responsible for the use, management and protection of forests have increased in number and have become increasingly more diverse in mission and organization. Such is often inconsistent with holistic approaches advocated for the management of large forest ecosystems. An assessment of state agencies affecting forest conditions in the North was undertaken in 2000-2001. The assessment found that such agencies are dispersed over all sectors and levels of state government; a state’s lead forestry agency is often only a small piece in the puzzle of state agencies affecting forests; consequences of fragmented state agency responsibility for forests are generally adverse, especially public confusion over agency roles and lack of integrated resource management; and coordination among state agencies affecting forest conditions takes many forms, although it occurrence is generally modest.Item State programs directed at the forestry practices of private forest landowners : program administrators assessment of effectiveness.(University of Minnesota, 1993-03) Cheng, Antony S.; Ellefson, Paul V.Item Trees + Me = Forestry: 4-H Youth Development Forest Resources Project, Intermediate Level(St. Paul, MN: University of Minnesota Extension Service, 1991) Kroll, Mary; Hansen, RobertThis book is for youth enrolled in the 4-H Forest Resources Project.
