Seismic lines are linear clearings created for petroleum exploration and are common in the western Canadian boreal forest. By favouring the growth of early seral vegetation, they can increase the abundance and palatability of woody browse, a ‘browse subsidy’ that may attract ungulates like moose (Alces alces) and white-tailed deer (Odocoileus virginianus), the main prey of wolves. Peatlands traditionally served as refugia from wolves for boreal woodland caribou (Rangifer tarandus caribou), but such subsidies may facilitate disturbance-mediated apparent competition, whereby predator activity associated with deer and moose raises incidental predation risk to caribou. We tested this ’browse subsidy’ hypothesis by comparing availability and proportional use of palatable winter browse on seismic lines and adjacent undisturbed forest plots across a gradient from upland to peatland forest in the Athabasca oil sands region of Alberta, Canada. Seventeen seismic lines were sampled, each with four paired plots across an ecological gradient from upland to peatland. Each plot pair compared the seismic line with the adjacent undisturbed forest. Seismic lines averaged 5.0 more highly palatable stems per 10 m2 (61.5 % more) than adjacent forest plots, while the proportion of stems browsed by deer and moose was 59.2 % higher on lines and increased with browse stem density. However, even after accounting for increases in browse availability, browse use remained higher on seismic lines relative to the adjacent forest, indicating selection of seismic lines by deer and moose. These results suggest that browse subsidy on seismic lines may contribute to disturbance-mediated apparent competition and declines in caribou, particularly where subsidies occur in or adjacent to peatland caribou refugia. Targeted restoration of high-subsidy lines could reduce deer and moose activity in these areas and thus potentially reduce predation risk for caribou.
地震线是为石油勘探而创建的线性空地,在加拿大西部的北方森林中很常见。通过有利于早期几种植被的生长,它们可以增加木质食物的丰富度和适口性,这是一种“食物补贴”,可能会吸引驼鹿(Alces Alces)和白尾鹿(Odocoileus virginianus)等有蹄类动物,它们是狼的主要猎物。泥炭地传统上是北方林地驯鹿(Rangifer tarandus caribou)的避难所,但这种补贴可能会促进干扰介导的明显竞争,因此与鹿和驼鹿相关的捕食者活动增加了北美驯鹿偶然被捕食的风险。我们通过比较加拿大阿尔伯塔省阿萨巴斯卡油砂区从高地到泥炭地森林的梯度上的地震线和相邻未受干扰的森林地块上美味的冬季浏览的可用性和比例使用来测试这种“浏览补贴”假设。17条地震线被采样,每条线有四个成对的地块,横跨从高地到泥炭地的生态梯度。每个图对将地震线与相邻未受干扰的森林进行比较。地震线平均每10 m2比邻近森林样地多5.0株(多61.5 %),而鹿和驼鹿浏览的茎在线上的比例高出59.2 %,并随着浏览茎密度的增加而增加。然而,即使考虑到可用性的增加,相对于邻近的森林,在地震线上的浏览使用仍然更高,这表明鹿和驼鹿选择地震线。这些结果表明,地震线上的浏览补贴可能会导致干扰介导的明显竞争和北美驯鹿数量的下降,特别是在泥炭地北美驯鹿保护区或附近的补贴。有针对性地恢复高补贴线路可以减少这些地区的鹿和驼鹿活动,从而潜在地降低北美驯鹿被捕食的风险。

Populus spp, vital fast-growing timber and ecological restoration trees globally, have growth and survival directly linked to forest ecosystem stability. With global warming intensifying heat stress events, Populus often faces growth inhibition, membrane damage, and metabolic disorders, threatening forest resilience. Iron chloride E6, a novel plant growth regulator, shows potential in enhancing stress resistance. This study aimed to improve thermotolerance of “84 K” poplar tissue cultured seedlings by screening optimal ICE6 concentration and elucidating its mechanism. Phenotypic observation initially screened concentrations from 0.01 to 0.08 μg/mL, with 0.04 μg/mL selected. High temperature stress tests measured physiological indices (chlorophyll, root activity, malondialdehyde, osmotic substances, antioxidant enzymes). Integrated transcriptomic and metabolomic analyses, along with gene expression profiling, were conducted. Results showed 0.04 μg/mL ICE6 significantly promoted seedling growth. Under stress, it reduced MDA accumulation, slowed relative conductivity increase, and enhanced osmotic and antioxidant capacities. Transcriptomics identified 3789 differentially expressed genes, while metabolomics detected 819 differentially accumulated metabolites. Key genes correlated with dehydroascorbic acid and 2,3-diketo-L-gulonic acid. Mechanistically, 0.04 μg/mL ICE6 maintained membrane integrity, alleviated oxidative damage, boosted antioxidants, and upregulated sugars/proline. Regulation involved hormone signaling, phenylpropanoid biosynthesis, and flavonoid related antioxidant metabolism. This study represents the first application of ICE6 in the large-scale propagation system of poplar tissue-cultured plantlets, filling a research gap in the use of novel regulators for stress resistance in forest tree tissue-cultured plantlets. By analyzing key targets mediating heat tolerance via ICE6 at transcriptional and metabolic levels, it provides insights for genetic improvement of poplar stress resistance from these dual perspectives. Furthermore, this work lays a theoretical and technical foundation for directional regulation of stress resistance during industrial production of tissue-cultured plantlets, ultimately contributing to enhancing the resilience of forest ecosystems under climate change.
杨树是全球重要的速生木材和生态恢复树种,其生长和生存与森林生态系统的稳定直接相关。随着全球变暖加剧热胁迫事件,杨树经常面临生长抑制、膜损伤和代谢紊乱等问题,威胁着森林的恢复能力。氯化铁E6是一种新型的植物生长调节剂,具有增强植物抗逆性的潜力。本研究旨在通过筛选ICE6的最佳浓度并阐明其作用机制,提高“84 K”杨树组培苗的耐热性。表型观察初步筛选浓度为0.01 ~ 0.08 μg/mL,最终选择0.04 μg/mL。高温胁迫试验测量了生理指标(叶绿素、根系活性、丙二醛、渗透物质、抗氧化酶)。进行了综合转录组学和代谢组学分析,以及基因表达谱。结果表明,0.04 μg/mL ICE6显著促进幼苗生长。在胁迫下,它减少MDA的积累,减缓相对电导率的增加,增强渗透和抗氧化能力。转录组学鉴定出3789个差异表达基因,代谢组学检测到819个差异积累代谢物。与脱氢抗坏血酸和2,3-二酮- l -谷氨酸相关的关键基因。在机制上,0.04 μg/mL ICE6维持了膜的完整性,减轻了氧化损伤,增强了抗氧化剂,上调了糖/脯氨酸。调节涉及激素信号,苯丙类生物合成和类黄酮相关的抗氧化代谢。本研究首次将ICE6应用于杨树组培苗大规模繁殖体系,填补了林木组培苗抗逆性新调控剂的研究空白。通过分析ICE6在转录和代谢水平上介导耐热性的关键靶点,从这两个角度为杨树抗逆性的遗传改良提供新的思路。为组织培养苗产业化生产过程中抗逆性的定向调控奠定了理论和技术基础,最终有助于提高森林生态系统对气候变化的适应能力。

Forest tree fructification cycles play a key role in planning the production of planting material and artificial regeneration of forests, especially in the context of changing climatic conditions. Cone harvest data reflects underlying reproductive cycles, but volumes are also influenced by seed demand and forest management decisions. Nevertheless, cone harvest remains a valuable proxy in forestry, as it reflects the availability of reproductive material essential for regeneration planning and nursery production. This comprehensive study analyzes the influence of temperature, precipitation, and the North Atlantic Oscillation (NAO) on the cone collection of seed material for four native Central European (Norway spruce, Scots pine, silver fir, European larch) and two introduced (Douglas-fir and grand fir) coniferous species. The quantity of cones harvested in the entire territory of the Czech Republic in 2004–2022 ranged from 78.7 to 396.9 t·ha−1·yr−1. The most intensively harvested tree species in the Czech Republic, Norway spruce (Picea abies [L.] Karst.), shows the most pronounced 2 and 3-year cycles, with a complementary 7-year cycle, with precipitation in April and October and lower temperatures playing a crucial role. Scots pine (Pinus sylvestris L.) dominates by 2.5 and 3.5-year cycles, influenced by precipitation in August and September and lower temperatures in September. Silver fir (Abies alba Mill.) shows 2.3-year cycles aligned with June precipitation, while European larch (Larix decidua Mill.) is influenced by the NAO, typically in 2-year cycles. Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) exhibits 2.2-year cycles linked to July precipitation and NAO in June, while grand fir (Abies grandis [Douglas ex D. Don] Lindley) exhibits 2.5-year cycles matching July precipitation. Of the forest tree species analyzed, Scots pine showed the highest correlation with the factors studied, while European larch had the lowest. The results show that tree seed crop cycles are strongly influenced by climatic fluctuations, which is essential for effective forest management. However, the 19-year dataset limits confidence in detecting longer-term cycles. Higher harvest volumes in species like Douglas-fir, grand fir and European larch are additionally affected by increased collection efforts. Understanding tree fructification cycles is crucial for planning, as climatic variations significantly affect reproductive success and the availability of planting material. Monthly variations in weather patterns notably affect the cone harvesting cycles of forest tree species.
森林树木的果实周期在规划种植材料的生产和森林的人工更新方面发挥关键作用,特别是在气候条件不断变化的情况下。圆果收获数据反映了潜在的生殖周期,但产量也受到种子需求和森林管理决策的影响。尽管如此,锥果收获仍然是林业的一个有价值的指标,因为它反映了再生规划和苗圃生产所必需的生殖材料的可得性。这项综合研究分析了温度、降水和北大西洋涛动(NAO)对四种中欧本土(挪威云杉、苏格兰松、银杉、欧洲落叶松)和两种引进(道格拉斯冷杉和大冷杉)针叶林树种球果收集种子材料的影响。2004-2022年捷克共和国全境的松果收获量为78.7 - 396.9 t·ha - 1·yr - 1。捷克共和国采伐最密集的树种是挪威云杉(Picea abies [L。[喀斯特]),2年和3年的周期最为明显,7年的周期互为补充,4月和10月的降水和较低的气温起着关键作用。苏格兰松(Pinus sylvestris L.)受8月和9月降水和9月低温的影响,以2.5和3.5年的循环为主。银杉(Abies alba Mill.)表现出2.3年的周期与6月降水一致,而欧洲落叶松(Larix decidua Mill.)受NAO的影响,通常以2年为周期。道格拉斯冷杉(pseudosuga menziesii [Mirbel] Franco)表现出2.2年周期与7月降水和6月的NAO相关,而大冷杉(Abies grandis [Douglas ex D. Don] Lindley)表现出2.5年周期与7月降水相关。在分析的森林树种中,苏格兰松与研究因子的相关性最高,而欧洲落叶松的相关性最低。结果表明,树木种子作物周期受气候波动的强烈影响,这对森林的有效经营至关重要。然而,19年的数据集限制了检测长期周期的信心。道格拉斯冷杉、大冷杉和欧洲落叶松等物种的高采收量也受到增加采集工作的影响。了解树木的结果周期对规划至关重要,因为气候变化会显著影响生殖成功和种植材料的可用性。气候模式的月变化显著影响森林树种的球果收获周期。

Phyllosphere microbiomes are essential to maintaining ecological balance and supporting host plant growth. It remains unclear how microbiomes, leaf traits and soil conditions synergistically regulate the nitrogen resorption efficiencies (NRE) during leaf senescence across forest types. We examined 16S rRNA and ITS sequencing to characterize the composition, diversity, function of the phyllosphere (epiphytic and endophytic) microbiome in both mature and senescent leaves in three representative subtropical forests, namely broadleaf, coniferous, and bamboo forests. Concurrently, the leaf physicochemical traits and soil nutrient and water were characterized. This study demonstrates community divergence was more significant in fungi than in bacteria across forest types. Furthermore, epiphytic communities exhibited stronger difference than endophytic communities. Regarding responsiveness to senescence, bacterial communities in broadleaf leaves were more sensitive than fungi, whereas fungi showed greater sensitivity in coniferous and bamboo leaves. There were significant differences in NRE among broadleaf (54.13 %), coniferous (45.09 %), and bamboo (39.78 %) forests. NRE in broadleaf forest depends on synergistic microbial metabolism, is constrained by benefit-risk trade-offs in coniferous forest, and is prone to resorption efficiency decline in bamboo forest due to multifactorial effects. This study proposes a tripartite coupling concept of "leaf traits-microbial functions-nitrogen resorption efficiency", which provides novel insights for forest nutrient cycling processes.
叶根圈微生物群对维持生态平衡和支持寄主植物生长至关重要。微生物组、叶片性状和土壤条件如何协同调节不同森林类型叶片衰老过程中的氮吸收效率(NRE),目前尚不清楚。通过对阔叶林、针叶林和竹林的16S rRNA和ITS序列分析,分析了阔叶林、针叶林和竹林成熟和衰老叶根圈(附生和内生)微生物组的组成、多样性和功能。同时对叶片理化性状和土壤养分水分进行了表征。该研究表明,在不同的森林类型中,真菌的群落差异比细菌更显著。附生群落比内生群落差异更大。在衰老响应性方面,阔叶细菌群落比真菌群落更敏感,而针叶和竹叶真菌群落对衰老的敏感性更高。阔叶林(54.13 %)、针叶林(45.09 %)和竹林(39.78 %)的NRE差异显著。阔叶林的NRE依赖于协同微生物代谢,针叶林的NRE受利益-风险权衡的制约,竹林的NRE受多因素影响容易导致吸收效率下降。本研究提出了“叶片性状-微生物功能-氮吸收效率”的三方耦合概念,为森林养分循环过程提供了新的认识。

Complete wood extraction is a widespread salvage logging practice after wildfire, implemented to obtain economical benefit and to reduce the risk of pest outbreaks. Such intense logging can strongly affect the ecosystem natural succession. In response, new sustainable approaches have been proposed to minimize impacts while still providing economical returns. In this study, we conducted a seven-year experiment to analyse the effects of different intensities of post-fire logging on vegetation structure and ground-level spider communities. We applied generalized linear mixed models (GLMMs) to test the effects of treatments and years since fire on vegetation structure, and spider functional traits. The most pronounced differences across logging treatments were observed in vegetation recovery, with sustainable practices promoting intermediate levels of regeneration between no intervention and conventional logging. Intense conventional logging tended to amplify the effects of fire on spider functional traits, whereas more sustainable logging practices facilitated a recovery trajectory more closely aligned with non-intervention. Measures such as the construction of woody piles proved particularly important during the early post-fire years, providing refuges that supported the initial recovery of spider communities. Overall, our findings highlight the effectiveness of sustainable techniques in balancing the economic benefits of logging with the need to minimize environmental impacts.
完全木材提取是一种广泛的森林火灾后救助性采伐方法,旨在获得经济效益和降低虫害爆发的风险。这种剧烈的采伐会严重影响生态系统的自然演替。为此,人们提出了新的可持续方法,以尽量减少影响,同时仍能提供经济回报。本研究通过7年的实验,分析了火灾后不同砍伐强度对植被结构和地面蜘蛛群落的影响。应用广义线性混合模型(glmm)研究了不同处理方式和火灾发生年限对植被结构和蜘蛛功能性状的影响。不同采伐处理之间最显著的差异是在植被恢复方面,可持续的做法促进了介于不干预和常规采伐之间的中间水平的再生。高强度的常规测井往往会放大火灾对蜘蛛功能性状的影响,而更可持续的测井方法则有助于与不干预更紧密地结合在一起。在火灾发生后的最初几年里,建造木桩等措施被证明尤为重要,它们为蜘蛛群落的初步恢复提供了避难所。总的来说,我们的研究结果强调了可持续技术在平衡伐木的经济效益和减少环境影响方面的有效性。

We applied generalized linear mixed models (GLMMs) to test the effects of treatments and years since fire on vegetation structure, and spider functional traits. The most pronounced differences across logging treatments were observed in vegetation recovery, with sustainable practices promoting intermediate levels of regeneration between no intervention and conventional logging. Intense conventional logging tended to amplify the effects of fire on spider functional traits, whereas more sustainable logging practices facilitated a recovery trajectory more closely aligned with non-intervention. Measures such as the construction of woody piles proved particularly important during the early post-fire years, providing refuges that supported the initial recovery of spider communities. Overall, our findings highlight the effectiveness of sustainable techniques in balancing the economic benefits of logging with the need to minimize environmental impacts.</div></div>","PeriodicalId":12350,"journal":{"name":"Forest Ecology and Management","volume":"606 ","pages":"Article 123549"},"PeriodicalIF":3.7,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146036232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expansion of moso bamboo (Phyllostachys edulis) is becoming increasingly common in subtropical forests, where low soil phosphorus (P) availability often constrains ecosystem productivity. Yet, it remains unclear how this expansion alters soil P availability and microbial metabolic P limitations. Here, we selected an expansion gradient in a natural forest region in southern China, consisting of a broadleaved forest (no expansion), a broadleaf–bamboo mixed forest (moderate expansion), and a pure moso bamboo forest (complete expansion). We measured soil P availability, physicochemical properties, extracellular enzyme activities, and plant stoichiometry. We found that compared to broadleaved trees, moso bamboo maintained comparable P levels in leaves and twigs but exhibited significantly lower P concentrations in roots and reduced available P in the rhizosphere. This indicates that moso bamboo possesses a highly efficient strategy for P uptake and internal translocation to support rapid growth. Importantly, ecoenzymatic stoichiometry in rhizosphere soil revealed that microbial P limitation in the rhizosphere intensified with the degree of expansion. These results indicate that the superior P acquisition strategy of bamboo depletes rhizosphere P, thereby exacerbating P limitation for soil microbes and potentially creating a competitive disadvantage for neighboring broadleaved species. Our study suggests that moso bamboo not only competes for P but also exacerbates microbial P starvation by altering the soil environment, potentially triggering cascading effects on key ecosystem processes such as nutrient supply and organic matter decomposition.
毛竹(Phyllostachys edulis)的扩张在亚热带森林中变得越来越普遍,在亚热带森林中,土壤磷(P)有效性低往往限制了生态系统的生产力。然而,尚不清楚这种扩张如何改变土壤磷有效性和微生物代谢磷限制。本文选取了中国南方某天然林区的扩展梯度,包括阔叶林(未扩展)、阔叶竹混交林(适度扩展)和纯毛竹林(完全扩展)。我们测量了土壤磷素有效性、理化性质、胞外酶活性和植物化学计量学。研究发现,与阔叶树相比,毛竹叶片和枝条的磷含量相当,但根系的磷含量明显降低,根际有效磷含量减少。这表明毛竹具有高效的磷吸收和内部转运策略,以支持快速生长。重要的是,根际土壤的生态酶化学计量表明,根际微生物磷限制随着扩张程度的增强而增强。这些结果表明,竹子优越的P获取策略消耗了根际P,从而加剧了土壤微生物对P的限制,并可能对邻近的阔叶物种造成竞争劣势。我们的研究表明,毛竹不仅竞争磷,而且通过改变土壤环境加剧微生物磷饥饿,可能引发对养分供应和有机质分解等关键生态系统过程的级联效应。

Human activities have significantly altered natural ecosystems, particularly through habitat loss and fragmentation in tropical regions. In southern Bahia, Brazil, cacao agroforests are widespread and provide important habitats for biodiversity amidst these changes. This study investigates the habitat use and dietary preferences of two frugivorous bat species, Carollia perspicillata and Rhinophylla pumilio, within these systems. We recorded 637 individuals of C. perspicillata and 66 of R. pumilio across 18 sampling sites, revealing that C. perspicillata is more abundant and adaptable to habitat heterogeneity, while R. pumilio shows a narrower distribution and specialized habitat preferences. Piper, a native herbaceous plant genus, was crucial to both species’ diets, being most frequently detected in C. perspicillata fecal samples (present in 94.4 % of sites) and also identified in R. pumilio samples. The strong association between Piper abundance and bat presence underscores its ecological importance in agroforestry landscapes. Additionally, C. perspicillata abundance increased with edge areas within a 500 m buffer, whereas R. pumilio responded better to localized features at a smaller scale (200 m). Other habitat metrics, such as forest cover, did not significantly impact bat abundance, suggesting that localized plant availability may be more critical for R. pumilio. These findings highlight the need to promote the retention of native flora, particularly Piper, within cacao agroforestry systems to enhance habitat quality for bats. Conserving native vegetation that support food resources like Piper at small to intermediate scales can support bat populations and, therefore, the essential ecosystem services they provide, such as seed dispersal.
人类活动极大地改变了自然生态系统,特别是通过热带地区栖息地的丧失和破碎化。在巴西巴伊亚州南部,可可农林业分布广泛,在这些变化中为生物多样性提供了重要的栖息地。本研究调查了这些系统中两种食果蝙蝠的栖息地利用和饮食偏好,即黑卡罗莱亚和矮鼻蝠。结果表明,在18个采样点上,黑桫椤(C. perspicillata)和矮桫椤(R. pumilio)分别记录了637个和66个个体,表明黑桫椤(C. perspicillata)数量更丰富,对生境异质性的适应性更强,而矮桫椤(R. pumilio)分布更窄,对生境的偏好更特殊。Piper是一种原生草本植物属,对这两个物种的饮食都至关重要,在perspicillata粪便样本中最常被检测到(存在于94.4 %的站点),在R. pumilio样本中也被发现。胡椒丰度与蝙蝠存在之间的强烈关联强调了其在农林业景观中的生态重要性。此外,在500 m缓冲带内,黑木丰度随着边缘面积的增加而增加,而小尺度(200 m)黑木对局域特征的响应更好。其他栖息地指标,如森林覆盖率,对蝙蝠的丰度没有显著影响,这表明局部植物的可用性可能对矮毛小毛猴更为重要。这些发现强调了在可可农林复合系统中促进本地植物群,特别是Piper的保留,以提高蝙蝠栖息地质量的必要性。在小到中等尺度上保护支持像Piper这样食物资源的本地植被可以支持蝙蝠种群,因此,它们提供的基本生态系统服务,如种子传播。

Retention and release of nitrogen, phosphorus, organic carbon, aluminum and iron by natural peatlands were studied in forested catchments in Finland. Peatlands were capable of retaining all other elements from their through-flow waters, except iron. However, relatively large mires (>50 % of the catchment area) from the viewpoint of routing runoff from managed forests to natural peatlands as a water management option were needed for efficient retention of nitrogen and organic carbon (>30–50 % retention). In contrast, aluminium and phosphorus were efficiently retained by relatively small peatlands (5–10 % of catchment area). We conclude that natural and well-established restored peatlands may be used in operational forestry as an efficient means to decrease phosphorus and aluminium loads, but the management of nitrogen, organic carbon, and iron loads by such peatlands may not be as feasible.
在芬兰的森林集水区研究了天然泥炭地对氮、磷、有机碳、铝和铁的保留和释放。泥炭地能够从流经的水中保留所有其他元素,除了铁。然而,从将径流从管理森林输送到天然泥炭地作为一种水管理选择的角度来看,需要相对较大的水坑(占集水区面积的50% %),以有效地保留氮和有机碳(保留30 - 50% %)。相比之下,相对较小的泥炭地(5-10 %的集水区)有效地保留了铝和磷。我们的结论是,自然和完善的恢复泥炭地可以作为减少磷和铝负荷的有效手段用于经营性林业,但这些泥炭地对氮、有机碳和铁负荷的管理可能不那么可行。

As extreme wildfire events become more frequent, understanding how forest treatments interact with wildfire is increasingly critical. However, assessing wildfire-treatment outcomes is challenging due to interactions among treatments, weather, topography, and fuels. We investigated wildfires from southern Wyoming to northern New Mexico to evaluate under what conditions treatments reduce the ecological impacts of fire, as measured by remotely sensed burn severity. We determined (1) factors influencing the relationship between treatments and burn severity, (2) how burn severity differed across forest and treatment types, and (3) how extreme burning conditions influenced outcomes. Treatment effects varied by forest types, with generally lower burn severity outcomes in lower elevation, frequent fire forest types compared to spruce - fir and lodgepole pine (higher elevation, infrequent fire) forests. Areas that previously burned at low to moderate severity or with prescribed fire had the lowest burn severity outcomes across forest types and even during extreme burning conditions. In contrast, treatments without fire (tree removal and/or surface fuels reduction) had mixed effects across forest types and had equivalent burn severity to untreated areas in infrequent fire forests during extreme burning conditions.
随着极端野火事件变得越来越频繁,了解森林处理如何与野火相互作用变得越来越重要。然而,由于处理方法、天气、地形和燃料之间的相互作用,评估野火处理结果具有挑战性。我们调查了从怀俄明州南部到新墨西哥州北部的野火,通过遥感烧伤严重程度来评估在什么条件下治疗可以减少火灾的生态影响。我们确定了(1)影响处理与烧伤严重程度之间关系的因素,(2)不同森林和处理类型的烧伤严重程度如何不同,以及(3)极端燃烧条件如何影响结果。治疗效果因森林类型而异,与云杉和黑松(海拔较高,火灾较少)森林相比,低海拔、频繁火灾的森林类型的烧伤严重程度通常较低。以前在低到中等严重程度或规定火灾下燃烧的地区,在所有森林类型中,甚至在极端燃烧条件下,烧伤严重程度最低。相比之下,不生火的处理(砍伐树木和/或减少地面燃料)对不同森林类型的影响好坏参半,在极端燃烧条件下,与不常见的火林中未经处理的地区的烧伤严重程度相当。
