New publication on invasive forest plant mangement

Prioritizing Invasive Forest Plant Management Using Multi-Criteria Decision Analysis in Minnesota, USA


Jason R. Reinhardt, Matthew B. Russell, and William F. Lazarus


Forests (2020)

How can we prioritize areas across a large landscape (in this case, the state of Minnesota) to manage specific invasive species? In the face of limited resources for management and landscape-level context that is often lacking, Silva Lab researchers look to answer these questions for five common invasive forest plants.

Recent publication by Silva Lab investigating eastern dwarf mistletoe and stand structure

Influence of eastern spruce dwarf mistletoe on stand structure and composition in northern Minnesota


Raychel Skay, Marcella A.Windmuller-Campione, Matther B. Russell, and Laura F. Reuling


Forest Ecology and Management, 481. (2021)


We examined black spruce stands with a range of eastern dwarf mistletoe infection levels. We found that infection by eastern dwarf mistletoe influences stand composition and structure and can lead in increased species diversity and richness in the overstory. As part of the natural disturbance regime of black spruce stands, eastern dwarf mistletoe can contirbute to stand- and landscape-level diversity.

New publication! Regeneration in black ash wetlands

Regeneration responses in black ash (Fraxinus nigra) wetlands: implications for forest diversification to address emerald ash borer (Agrilus planipennis)


Marcella A. Windmuller-Campione, Matthew B. Russell, Robert A. Slesak & Mathew Lochner 


New Forests (2020)


Researchers looked at sturcture and composition of regeneration in black ash wetlands following harvesting using three different silvicultural systems. Site quality and depth of soil muck were found to be important factors in regenerating species other than black ash, while residual overstory density was not. Site-specific factors are important when selecting a silvicultural system in black ash wetlands, and managers working in richer sites with shallower soil muck may have more options.

New publication from the Silva Lab on ash wood products and EAB


Perspectives on Ash Wood Utilization and Marketing in Anticipation of Emerald Ash Borer in Minnesota 


Matthew B. Russell and Elizabeth C. Ring


Forest Products Journal (2020) 70 (3): 279–282.


We survey professionals in forest products and natural resources about their perspectives on current and potentially emerging markets for ash wood in Minnesota. Due to impacts of emerald ash borer, there is likely to be a large amount of ash wood available over the next 10 years, but if new markets and products are not developed, there may be little demand for the species.

New publication from the Silva Lab on distribution of invasive plants


Assessing the current and potential future distribution of four invasive forest plants in Minnesota, U.S.A., using mixed sources of data


Jason R. Reinhardt, Matthew B. Russell, Senait Senay, and William Lazarus 


Scientific Reports, Volume 10, Article number: 12738 (2020) 


We predicted the potential current and future distributions of common buckthorn (Rhamnus cathartica), glossy buckthorn (Frangula alnus), garlic mustard (Alliaria petiolata), and multiflora rose (Rosa multiflora) under different climate change scenarios 30 and 50 years into the future.

New publication from the Silva Lab on silvicultural practices in Minnesota


The Decline of the Clearcut: 26 Years of Change in Silvicultural Practices and Implications in Minnesota


Marcella A. Windmuller-Campione, Matther B. Russell, Eli Sagor, Anthony W. D’Amato, Alan R. Ek, Klaus J. Puettmann, Madison G. Rodman


Journal of Forestry, Volume 118, Issue 3, May 2020, Pages 244–259


We analyzed silvicultural practices and forest management activities across different ownerships in Minnesota from 1991 to 2017. The percentage of forest area harvested using the clearcut method decreased during the time period studied, while shelterwood, seed tree, selection and thinning treatments increased.

Minnesota SAF Winter Meeting

Several members of the UMN Silva Lab attended and participated in the Minnesota Society of American Foresters winter meeting in Brainerd, MN. The theme of the meeting was Ecosystem Management in the 21st Century. It was a great opportunity to share our work, to learn from others, and to see the University of Minnesota students win the Knowledge Bowl! Congratualtions also go out to Jamie Mosel, winner of the student poster contest. Her poster, titled Drought, Forest Management, and Climate Adaptation: Adaptive Silviculture for Climate Change and Seedling Responses was very informative and also contains her own original artwork!

New publication from the Silva Lab on EAB and nitrogen cycling

Effect of simulated emerald ash borer infestation on nitrogen cycling in black ash (Fraxinus nigra) wetlands in northern Minnesota, USA


Alan J.Z.Toczydlowski, Robert A.Slesak, Randall K.Kolka, Rodney T. Venterea, Anthony W. D'Amato, and Brian J.Palik

After six years of simulated emerald ash borer disturbance to black ash wetlands, we used an in-situ soil core incubation and laboratory analysis to assess EAB's impact on nitrogen cycling. Differences in water table level, temperature, and vegetation communities among treatment plots had limited, but potentially consequential effects on N cycling in black ash wetland soils.

Silva: the forest trees of a region or country

- Merriam Webster


The Silva Lab Group is a collective of faculty, researchers, and students at the University of Minnesota who study Biometrics, Forest Health, Forest Soils, and Silviculture.

In the Silva Lab, we create and address research questions about forested ecosystems to develop a better understanding about mechanisms affecting our forests and to best inform management. We are based in the Department of Forest Resources and work collaboratively with public agencies, local stakeholders and across disciplines on many projects.
