Management and restoration efforts are complicated by diverse and abundant nonnative invasive plants, including Ailanthus altissima. Verticillium nonalfalfae has been identified as a potential native mycoherbicide option for Ailanthus. To test the efficacy of Verticillium on Ailanthus we designed a study in highly disturbed forests of southern Ohio. At each of five sites, we monitored symptomology, mortality, and rate of spread of stem-inoculated Verticillium on Ailanthus in four inoculated plots and compared it to a control plot. We also monitored native plants for Verticillium symptomology and community responses to Ailanthus control. Our results suggest that Verticillium is an effective tool for controlling Ailanthus with no observed effect on native flora. Further, Verticillium naturally spreads through stands and mortality is slow enough that other resident nonnative invasive plants do not rapidly increase.\u0000 Study Implications: Managing problematic invasive plants is a costly and time-consuming endeavor that quickly overwhelms resources. The identification and development of native biocontrols will help to suppress invasive plants, especially when considered in conjunction with other control options. Native biocontrols are pests or diseases that are typically nonlethal residents of the local environment but have significant and detrimental impact on nonnative plants. The native fungus Verticillium nonalfalfae along with several other Verticillium species has been identified to kill the invasive Ailanthus altissima. Verticillium can be applied to a subset of Ailanthus stems, and through time, will spread naturally with minimal impact to native species.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"67 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83162083","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}

{"title":"Forest-Wide Longleaf Pine Restoration Response to Varying Future Management Intensities in a Transitioning Upland Forest","authors":"George Matusick, S. Hudson, Caleb Garrett, James D. Kent, J. Parker","doi":"10.1093/jofore/fvac008","DOIUrl":"https://doi.org/10.1093/jofore/fvac008","url":null,"abstract":"\u0000 Many public land management programs in the southeastern United States have been restoring the longleaf pine forest for more than 20 years, which includes intensive treatment with fire, thinning, chemical control of competition, and tree planting. A shift to more passive management (prescribed burning alone) is anticipated once a critical level of longleaf pine has been established. It remains unclear whether this longleaf pine threshold has been reached and whether intensive management should continue at Fort Benning, Georgia. Using the Landis-II forest landscape model, changes in tree species and forest types were estimated from 2017 to 2117 under four forest management scenarios, ranging from passive (“burn only”) to intensive (“proactive”). The desired future condition includes 75% of upland forest dominated by longleaf pine (>49.5% composition). The proactive scenario resulted in the desired future forest condition, whereas reactive and passive scenarios did not. These results suggest a critical threshold of longleaf pine forest has not been reached at Fort Benning and therefore intensive management approaches are still required. This study shows that even well-established populations of longleaf pine on public lands require maintenance and continued intensive restoration to reach desired forest-wide conditions.\u0000 Study Implications: The study illustrates the use of a forest landscape model to examine the implications of multiple practical forest management scenarios. Despite over 20 years of intensive longleaf pine forest restoration across the study forest, proactive management approaches remain necessary to reach desired future forest conditions. A shift to passive management at this point is expected to result in significant areas with no longleaf pine and a substantial population of hardwood forest (representing a departure from desired conditions). The main findings can be extended to other forests in the region where restoration of upland longleaf pine forest is a primary objective.","PeriodicalId":23386,"journal":{"name":"Turkish Journal of Forestry","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82133863","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}

Through ninety-six interviews across nine western states with Forest Service and state agency staff and partners, we researched how the Shared Stewardship Strategy was being translated into practice. We found that, in most states, actors have relied on existing programs and partnerships to set the foundation for Shared Stewardship. Some states developed new positions or committees to support enhanced coordination, inclusive representation, and joint prioritization. Interviewees said that realizing shared accountability among partners and trying new approaches required training staff on existing mechanisms to work across jurisdictions and clear communication and support from leaders.

Prescribed burning with a focus on managing duff has therefore been recommended for mitigating negative impacts on overstory trees when fire is reintroduced. We modeled the economic outcomes of different forest management scenarios related to burning for duff management in even-aged longleaf pine stands. We considered five management scenarios in which we varied prescribed fire use, thinnings, mortality rates, and salvage logging. Our findings indicate that burning for duff management without and with thinnings can be considered the most economically viable strategy ($1593/ha–$966/ha).\u0000 Study Implications: Prescribed fires after long periods of fire exclusion can consume significant amounts of forest floor duff fuels causing heavy overstory pine mortality.

(0–5.1 cm), we define 171 and 691 stems ac−1 (422.5 and 1,707.5 ha−1) as lower and upper full stocking thresholds for basic NHF management goals (wood and biomass productivity) and overabundant/pest–pathogen-challenged species. We define component stocking targets as 15% of full stocking targets for six additional wildlife (e.g., nut producers) and resilience (e.g., pest–pathogen) goals and individual species representation.

At low threshold, 33% of stands were understocked for biomass and wood goals, whereas 67% were fully stocked with overabundant/pest–pathogen-challenged species.

Stocking outcomes could likely be improved via more intense overstory harvests and mitigation of deer impacts. Second, most stands meeting stocking goals are vulnerable to future changes in climate and pest–pathogen outbreaks, given stocking is often dominated by a small subset of candidate species.

Here, we describe a field study to characterize BWA infestation and effects on host trees in Idaho from the onset of infestation within twenty-eight sites with repeated surveys in 2008, 2013, and 2018. Declining tree health was categorized into five BWA damage classes based on the percent of the tree crown–expressing symptoms caused by BWA. Between 2008 and 2018, BWA presence increased across most sites regardless of host species, with an average of 48% (0.1%–100%) host trees per acre being infested. Severe damage or mortality of true fir from BWA occurred across thirteen sampled forest habitat types, including those representing harsh, high elevations. Although a significantly greater proportion of subalpine fir died than grand fir by 2018, BWA caused grand fir mortality. All diameter size classes became infested with BWA, including seedlings, and BWA caused mortality regardless of tree diameter.

This simple and effective five-tiered classification system can be used to categorize BWA damage within individual trees or stands based on the collective symptoms caused by the insect. Feeding by BWA can ultimately result in stand-level mortality of both over- and understory fir and may require artificial regeneration to restore forest function. Fir regeneration was abundant at most BWA-damaged sites; however, seedling-sized firs were often heavily gouted from BWA to levels that will prevent them from growing into seed-bearing trees.
