Growth of European beech recovered faster than that of Norway spruce after a five-year experimental drought in a mixed forest stand

Trees, Год журнала: 2023, Номер 37(6), С. 1695 - 1715

Опубликована: Окт. 6, 2023

Abstract Key Message Beech growth acclimated better during severe drought and recovered faster than spruce after ended. This was associated with a shift in performance along relative tree size towards small trees. The effects of several consecutive years the recovery reaction mature trees particular long-term have been poorly studied so far. In this study, we demonstrate reactions five-year treatment extended summer droughts, followed by controlled irrigation very productive mixed forest stand. We exposed 70-year-old Norway ( Picea abies [L.] Karst) 90-year-old European beech (Fagus sylvatica [L.]) to reduced precipitation using automatic throughfall exclusion TE ) roofs growing seasons from 2014 2018, irrigated early 2019 removed thereafter. From 2009 2022, monitored annual on 6 plots ambient Control conditions CO KROOF canopy experiment. lost significant drought, some dying others remaining at low level without stress. also significantly beginning but emerged stronger group. Spruce showed non-significant trend increased inter-specific compared intra-specific drought. found that benefitted more mixture phase itself. Most importantly, observed smaller for both species. change relationship between diameter increment is major finding our study suggests possible response mechanism prolonged key observation requires further investigation should be considered future management strategies under changing climatic conditions.

As climate change continues, forests are increasingly suffering from drought stress, which is leading to widespread forest dieback, but also increased mortality of individual trees. In this regard, the impact small-scale differences in water availability on trees has not yet been sufficiently studied determine possible responses different tree species future droughts. Since conventional soil moisture monitoring and sampling methods only consider single points or small volumes, Electrical Resistivity Tomography (ERT) becoming important cover a larger survey area detect heterogeneities with regard properties moisture. The current study describes application combined two- three-dimensional geoelectrical approach daily measurements over two years (May 2021 – April 2023) ecosystem Lower Franconia (northwestern Bavaria, Germany), strongly affected by change. Soil content, matric potential, throughfall, stem flow measured at site as well precipitation an adjacent clearing. seasonally (long-term) precipitation-driven (short-term) temporal resistivity correlated content potential. applied 3D-ERT allowed first subsurface below European beech located middle measuring grid resolution. corresponding results provide indications that besides changes chemical processes may influence sites. show very suitable for investigating short- long-term variations moisture, understanding causal relationships considering subsurface.

Drought legacy in mature spruce alleviates physiological stress during recurrent drought

Plant Biology, Год журнала: 2025, Номер unknown

Опубликована: Май 16, 2025

Abstract Forest ecosystems are facing severe and prolonged droughts with delayed recovery, known as “drought legacy”. This study presents positive legacy effects following a long‐term, experimental drought subsequent recovery in mature mixed Norway spruce European beech forest. Approximately 50 trees were exposed to five consecutive years of summer by completely excluding growing season precipitation from May 2014 June 2019. Experimental started July 2019, after which the received natural precipitation. Taking advantage 2022, unique long‐term drought, we investigated how affects tree physiological responses recurrent drought. The resulted 60% reduction leaf area, was still reduced 30% 4 release. slow associated water use higher soil availability under during 2022 leading significantly stress: about two times predawn potential, gas exchange sap flow density compared previous controls. Furthermore, neighbouring beech, displaying no area also had potential controls, likely benefitting spruce. pronounced effect proved advantageous for alleviating stress overcoming future events.

Abstract Key message Considering their drought tolerance and growth characteristics, rare native tree species are well-suited admixed for the development of climate-stable forests in Central Europe. In our study, we assessed reaction four European hornbeam ( Carpinus betulus L.), white elm Ulmus laevis Pall.), field maple Acer campestre wild service Sorbus torminalis (L.) Crantz). Based on tree-ring data, (I) evaluated species-specific characteristics variability examined influencing site annual growth. (II) We quantified to single events, also depending variables. (III) compared results oak Quercus robur L., petraea (Matt.) Liebl.) beech Fagus sylvatica L.). As they well-known species, there is a broad knowledge about response across wide geographical ranges available. Bringing relation with it allows categorise contextualise performance. Our show, that besides elm, showed an overall lower higher than oak. However, especially were better adapted partially even recovered Combining aspects stability tolerance, conclude well suited as future forest stands. suitable match wetter sites, while sensible complement climate stable drier sites.

Structural and compositional acclimation of forests to extended drought: results of the KROOF throughfall exclusion experiment in Norway spruce and European beech

Trees, Год журнала: 2023, Номер 37(5), С. 1443 - 1463

Опубликована: Июль 31, 2023

Abstract Drought effects on tree growth and mortality are widely studied, but scant knowledge exists its impact stand density, size variation, or mixing proportions. Grasping drought's influence structural compositional diversity is crucial for dynamics, ecosystem services, silvicultural adaptation. We relied KROOF, a 5-year throughfall exclusion experiment in mature Norway spruce ( Picea abies ) European beech Fagus sylvatica stand, to analyze attributes, including Stand Density Index (SDI), Growth Dominance Coefficient (GDC), species proportion. Our study demonstrates that drought-induced reduction loss decreased SDI by 27%, proportion 41% at spruce’s expense, homogenized structure. Furthermore, we reveal proportion, were more affected spruce, stabilizing the level. Extended drought significantly altered partitioning favor of smaller trees, with 70% growth-size relationship slope 157% decrease GDC. Species-level analysis indicated stronger shift towards particularly spruce. discuss longer periods may trigger acclimation levels, potentially underestimated when based solely individual years. Sustained stress could induce across various from cohort, tree, organ. Maintaining mitigate future growth, mortality, structure, as exemplified extended experimental drought. suggest approaches better attuned natural processes amid climate change.

Coal mining reclamation as an environmental recovery effort: a review

Journal of Degraded and Mining Lands Management, Год журнала: 2023, Номер 10(4), С. 4811 - 4811

<p>The exploitation of natural resources remains a common practice in many countries to stimulate economic growth, and coal is the most commonly exploited resource. However, mining process often causes environmental disturbance. Therefore, this research was conducted analyze ideal implementation mine reclamation Indonesia. In post-mining area, land arid, with voids that are prone flood erosion. The area carried out by returning topsoil, adding organic material, planting cover crops fast-growing species. When topographical conditions have steep slopes, scrap engineering added hills up maximum height 8 meters, trimming slope remaining 35 degrees making drainage channels width more than 3 depth 2 an edge 2-5 percent. Approximately 70.59% programs Indonesia aimed at reforesting areas into secondary forests because they were previously forest ecosystem. types had been but still uncommon included aquaculture, urban forests, parks playground, sports park, cattle farms, fauna conservation ecotourism. A new approach reclamation, such as eco-habitat, important obtain optimal social, economic, ecological benefits. This involves optimizing sources livelihood based on rezoning according level interference, revegetation plants involving community, revitalization community livelihood, specifically restoration plant species food, nutrition, minerals, income, non-timber products. program should be through collaborative partnership between companies, local communities, academics, technical ministries, media.</p>
