Winners and losers of climate warming: Declining growth in Fagus and Tilia vs. stable growth in three Quercus species in the natural beech–oak forest ecotone (western Romania)

Forest Ecology and Management, Journal Year: 2022, Volume and Issue: 506, P. 119892 - 119892

Global warming and increasing drought severity are exposing temperate forests to stress, challenging silvicultural decision making. Growth analyses in marginal tree populations at drought-induced range limits may provide valuable information on species' adaptive potentials species-specific climate turning points. We studied the sensitivity resilience of radial growth, long-term growth trends mesic rear-edge Fagus sylvatica comparison three oak species (Quercus petraea, Q. frainetto, cerris) Tilia tomentosa natural ecotones from beech xeric along elevation transects western Romania. Radial all was positively influenced by summer precipitation low intensity, negatively high temperatures. The basal area increment (BAI) F. T. has declined last 10–20 years with a deterioration water balance, while Quercus maintained stable rates, though lower BAI levels, suggesting negative relationship between mean resistance among five species. reductions during severe events (2000, 2003, 2012) were stronger, lower, than species, pointing thermal limit June–August temperatures 20–21 °C. As is similar predicted colline/submontane Central Europe about 50 years, decline vitality likely also drought-affected regions distribution centre future warming. Our results demonstrate that choosing stress-tolerant petraea (as well as frainetto instead more productive timber relatively safe option for European forestry warmer climate.

Oak declines: Reviewing the evidence for causes, management implications and research gaps

Ecological Solutions and Evidence, Journal Year: 2024, Volume and Issue: 5(4)

Abstract Oak decline is a complex disorder caused by multiple stressors. Although declines have been observed across Europe since 1700, there still lot of uncertainty around the cause, and therefore appropriate management techniques. Using literature from European oak ecosystems, this review perspective discusses key stressors associated with in Quercus robur L. Q. petraea (Matt.) Liebl. newly described acute breaking out United Kingdom (and beyond), view to identifying important evidence gaps implications. The factors implicated include drought, pests pathogens. These can interact positive feedback loops increase stress within oaks. Extreme frost, waterlogging, soil properties, land management, nitrogen pollution, heavy metal genetic predisposition mycorrhizal changes could also be involved decline, but more research required understand these. In necrotic lesions are bacterial up three species, it has that presence wood borer Agrilus biguttatus Fabricius 1776 amplify symptoms. Practical implication: amount each stressor contributes towards these ‘tipping points’ largely unknown likely differ between events, sites even individual trees. This makes advice provision exceedingly difficult. Historic records show oaks recover; therefore, allowing trees time space recover should priority for practitioners. Future recommendations effective declining discussed.

The decline of perennial plant species, including oak, olive, and kiwifruit, is a phenomenon currently observed in many areas the world. In this review, such species are chosen precisely because, despite differences their botany, native distribution, current utilization, they all affected by significant global or local declines. An analysis main common causes involved could be useful for better understanding phenomenon. Quercus impacted “Chronic Oak Decline” (COD), “Sudden (SOD), “Acute (AOD). Italy, olive groves severely damaged “Olive Quick Decline Syndrome”, whereas kiwifruit orchards struck “Kiwifruit Vine Syndrome” (KVDS). Among abiotic inciting stressors, drought, warmer temperatures, waterlogging, within climate change scenario, declines described herein as well dysbiosis. involvement some aggressive phytopathogens another feature these Oomycetes contribute to COD, SOD, KVDS; Xylella fastidiosa subsp. pauca Botryosphaeriaceae affect enterobacteria AOD, representing decisive contributing factors. These quite complex, comprehensive approach required dissect facets involved.
