{"title":"Forest Biomass Feedstock Availability and Economic Contribution of Biopower Facilities in the Lake States Region","authors":"Raju Pokharel, J. Poudel, Ram P. Dahal, Shivan Gc","doi":"10.1093/jofore/fvad023","DOIUrl":"https://doi.org/10.1093/jofore/fvad023","url":null,"abstract":"\u0000 The Lake States (MI, MN, WI) region holds 54.8 million acres of forest and offers the potential to meet the increasing demand for sustainable energy through forest biomass. The objective of this study is to estimate the annual availability of biomass, after considering the sustainability threshold, for a wood price and its economic impact in the Lake States region. This study identified twenty-seven active power facilities using biomass in addition to oil, gas, and coal, with a total capacity of 3.85 million MWh per year. They consumed 2.80 million dry tons of biomass in 2019. At the current delivered wood price, an additional 9.72 million dry tons of biomass is economically available, which, if used, would generate an additional 11,112 jobs (1,583 direct and 9,529 indirect and induced), $1.54 billion in value added ($803 million direct and $733 million indirect and induced), and $2.71 billion ($1.46 billion direct and $1.25 billion indirect and induced) in total output. Operating at least one-third of the existing capacity for biomass-based power generation would add 1,969 jobs, $293 million in value added, and $413 million in total output. The expansion of the biomass biopower industry has the potential to significantly increase economic impact, especially in rural areas.\u0000 Study Implications: Mapping procurement zones for resource allocation using delivered wood prices for biomass helps identify the economic availability of biomass for electric power production in the Lake States. Our results establish the market extent for biomass and identify potential areas where investment in biopower production or capacity upgrade is feasible. This study also provides insight into the economic impacts of additional biomass utilization to produce power. Most of these impacts would come about in rural areas, improving economic growth in these communities. A combined analysis estimating the potential supply and demand and the economic effects of biopower industry expansion provides valuable insight into decision-making for state forest action plans and private sector forest management plans. Furthermore, the findings from this study will help inform effective regional policy and investment decisions on biomass power industries. The method used can also be tailored to a specific facility to estimate its procurement zone, feedstock availability, and economic impacts.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90738088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the study period, 61,698 contracts were awarded to 7,896 businesses, totaling $12.9 million, to perform labor-intensive forestry work, with most work being contracted for wildfire-related activities. Businesses were typically located in western states and non-minority owned businesses received the majority of contracts. Of minority-owned businesses, Hispanic American–owned businesses received the most contracts. The median distance that businesses traveled to accomplish work increased significantly through time but differed by business type. Understanding the scope and work of businesses awarded contracts provides insight into the workforce and its relationship to marginalized populations. Strategic investment in this workforce may have widespread impacts on federal, state, and local economies and the livelihoods of forest workers.\u0000 Study Implications Between 2001–2020, the USDA Forest Service spent billions of dollars on contracts with thousands of businesses to conduct labor-intensive forestry projects; however, project locations and awarded businesses were not evenly distributed through space and time. Emerging and minority businesses represented a small proportion of contracts awarded. Advancing understanding of the businesses conducting labor-intensive forestry work lays the foundation for inquiry into the working conditions forest workers experience as well as disparities in contract capture. Some regions may have benefitted more from contract capture than others. Understanding factors enabling places and businesses to capture these contract dollars may help identify others that may benefit from investment.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77679585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Foresters are often on the frontlines of these impacts, tasked with quickly adapting management plans to recover potential economic losses and maintain future silvicultural options following tree species loss. We highlight that the irreplaceable cultural and ecological values provided by many tree species argues for renewed focus on applying integrated pest management and adaptive strategies in novel ways to sustain these values for future generations. To guide these efforts, we describe a framework for adapting to NIIP centered on three interrelated components: preservation value, preservation approach, and preservation strategy. This framework and emerging species preservation efforts provide an alternative path forward to sustain threatened species and their associated values in an era of increasing change.\u0000 Study Implications: The impact of non-indigenous insects and pathogens (NIIP) is one of the greatest challenges facing the long-term stewardship of forests in North America. Species preservation efforts that apply integrated pest management and adaptive strategies to maintain species in the face of NIIP are increasingly needed in foresters’ toolboxes to address these novel threats. Identifying the preservation values (ethical responsibility, cultural integrity, ecological function, genetic conservation) tied to a species preservation effort will help guide how preservation approaches and strategies are applied at stand and landscape scales to sustain species and associated cultural and ecological values into the future.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88584300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We administered a mail survey to 1,000 randomly selected nonindustrial private forest landowners in the Panhandle of Florida who owned forestlands in the counties most severely affected by Hurricane Michael. Results show that most landowners did little to no forest management to prepare for the hurricane. Following Hurricane Michael, 34% of respondents reported increased invasive plants whereas 82% experienced timber loss, 62% had damaged wildlife habitats, and 53% had increased vulnerability to wildfire hazards. Landowners who experienced timber damage from Hurricane Michael were more likely to reduce fire hazard, eliminate or reduce invasive plants, perform road and trail maintenance, improve wildlife habitat, reforest both salvage harvested and areas that were not salvage harvested, search for information on the internet about forest management, and pass their forestland to family.\u0000 Study Implications: Forest disturbances such as hurricanes, invasive species, and wildfires are predicted to increase in severity and frequency, consequently affecting forest productivity, sustainability, and management. Despite significant impacts on forest lands, there is limited understanding of how these disturbances may affect nonindustrial private forest landowner management behaviors. This article highlights the attitudes, experiences, and perceptions of nonindustrial private forest landowners, including their awareness and overall forest management plans regarding invasive species control, wildlife habitat improvement, and reducing wildfire hazards after a hurricane. We assessed the important factors that contribute to landowners’ willingness to take action to address these interacting forest disturbances.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90619304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Foresters can help expand the maple syrup industry by supporting private forest management decisions to improve maple tree health and sap production. This study examined the influence of advice solicitation, active listening, and forester traits (i.e., expertise, confidence, trustworthiness, shared forestland values) on outcomes of professional advice about maple syrup production and sugarbush management. Regression models were used to analyze data from a survey targeted at Wisconsin maple syrup producers (n = 149). Compared with unsolicited advice, advice outcomes were more positive when landowners actively sought it, although advice solicitation had a stronger influence on perceived quality of advice than advice utilization. Landowners evaluated advice more positively and had greater intention to use the advice when the forester actively listened to them. Perceiving positive traits in the forester has the strongest impact on landowners’ evaluations and adoption of advice.\u0000 Study Implications: By examining the role of forester traits, giving (un)solicited advice, and active listening in affecting private forest landowners’ perceptions and use of advice about maple syrup production and sugarbush management, this study informs the design of training programs aimed at equipping foresters with effective communication skills. To achieve optimal communication outcomes, foresters should tactfully create the perception that the landowner requested their advice, such as by eliciting questions and encouraging landowners to explain their management motivations. Further, foresters should demonstrate expertise, show confidence, build trust, and create compatible management philosophies with the landowner by acknowledging the landowner’s perspectives.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"60 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90203783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Few surviving overstory ash trees exist in areas first invaded by EAB, such as the Lake States region; however, forests with healthy, mature ash remain in recently invaded regions, such as the northeastern United States. Given the importance of ash to cultural lifeways of Indigenous peoples and the ecology and economies of working forest lands, there is growing interest in applying protection measures to maintain ash in forested settings. We further develop our call for species preservation by presenting Indigenous and Western science case studies of ongoing efforts to mitigate the impacts of EAB, illustrating specific applications of these strategies for meeting different preservation goals in lowland and northern hardwood forests in northeastern North America.\u0000 Study Implications: The introduced emerald ash borer (EAB) threatens to functionally eliminate ash species from large portions of the United States. Although the impacts of EAB are now widespread in many areas, portions of the United States, such as the Northeast, still contain forests with healthy, mature ash. This presents a unique opportunity to apply the integrated pest management strategies and knowledge gained from other invaded regions to preserve the cultural and ecological values provided by ash in the forest. Multistakeholder partnerships built around preserving the cultural and ecological values of ash have provided a powerful approach for sustaining ash into the future.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"154 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79687659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Planting density greatly affects reforestation costs. It also influences when vegetation starts competing inter- (and intra)-specifically for limited site resources, and when thinnings occur. Planting 600 seedlings per acre essentially forces landowners into two thinnings prior to a final clearcut. However, many landowners are finding it difficult to conduct first thinnings; poor pulpwood markets and lack of interest from loggers have become common. Reforestation costs have increased due to inflation. Thus, given better seedlings, a need for reduced reforestation costs, and the inability of landowners to conduct pulpwood-dominated thinnings, most landowners should plant near 450 seedlings per acre. Here, landowners have more flexibility to adjust to market conditions. If pulpwood markets improve they can participate, but a “pulpwood” first thinning is not absolutely needed. Plus, entry into more valuable chip-n-saw and sawlog markets should occur sooner.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"1965 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91041090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research used in-depth interviews to explore variable support or opposition to three fuels-reduction projects occurring in the same region of north central Washington State, USA. Results indicate that differential support or opposition to each project stemmed from a unique combination of social factors operating in each locality (e.g., past history with fuels treatments, values for public land, environmental advocacy networks), the relationships that local populations had with agency members conducting each treatment, and the ways that managers engaged populations in the design of each treatment. We used existing frameworks for understanding collaborative potential/environmental conflict and for documenting the influence of local social context on adaptive wildfire actions to help explain emergent lessons about support or opposition to each project.\u0000 Study Implications: Our results illustrate how support or opposition to proposed fuels-reduction treatments can emerge among socially diverse human “communities” occupying the same small region. We melded existing theoretical concepts and literature to advance an expanded framework for understanding the ways that local social context or circumstances interact with broader agency, political, or procedural processes to influence local support or opposition to fuels treatments.

This research evaluated the effectiveness of functional zoning based on site index on forest sizes relevant to family forest owners. A total of fifty family forests were randomly selected from twenty-five counties in the East Texas Pineywoods region. Timber production and northern bobwhite habitat (Colinus virginianus) habitat were used as proxies for competing objectives. It was found that 80% of family forest parcels had sufficient site index heterogeneity to benefit from functional zoning. For forest parcels that could benefit from functional zoning, the benefit in terms of increased land expectation value (LEV) was not found to be dependent on parcel size. On average, this approach increased the LEV $32/ac at a 3% discount rate, $16/ac at 5%, and $9/ac at 7%. This zoning approach supports multiple objectives while minimizing the economic impact of the nonrevenue objectives.\u0000 Study Implications: This study illustrates an approach to managing a forest for multiple competing objectives typical of the US South. The study findings show that many small forest tracts can benefit from functional zoning based on site index and could therefore be of interest both to family forest landowners and forest managers.
