“…Large-scale dieback or mortality of elm species due to DED has recently been reported in countries neighboring South Korea, including Russia [22] and Japan [23]. These are areas relatively distant from Korea, but it remains possible that these are the likely origin of the disease found in the present study.…”

During a routine survey conducted in July 2021, several dead and dying Ulmus macrocarpa trees were observed in an urban forest located in the Gyeonggi Province of South Korea. The trees had symptoms of wilt with yellowing and browning of leaves, and, in most cases, the trunks of dying trees were infested by bark beetles. Isolations were made from small pieces of wood taken from dying trees, and beetles were collected from the infested stems. Fungal isolates and the beetles were identified using DNA sequence-based phylogenies and morphology, respectively. The results revealed that the fungus was Ophiostoma novo-ulmi, the causal agent of Dutch elm disease, and the associated bark beetle was Scolytus jacobsoni. This study provides the first record of Dutch elm disease in South Korea and suggests that a nationwide survey for the disease should be undertaken.

“…Rootsis on jalakasurma tõttu kohalike liikide (U. glabra, U. laevis, U. minor) arvukus vähenenud sellisel määral, et need on võetud punasesse nimistusse (Hallin, 2010). Peterburis anti ainuüksi 2015. aastal välja üle 5000 raieloa surevate jalakate eemaldamiseks (Jürisoo et al, 2021a).…”

“…Balti riikidesse ja Venemaale jõudsid need hübriidid piiride avamise järel. Praeguseks on neid hübriide juba tuvastatud Norras, Rootsis (Brasier & Kirk, 2010), Leedus (Motiejūnaitė et al, 2016), Lätis (Matisone et al, 2020) ja Loode-Venemaal (Peterburg) (Jürisoo et al, 2021a). Hübriidide suurema agressiivsuse tõttu kasvab oht jalakate populatsioonile tulevikus veelgi (Ellstrand & Schierenbeck, 2000).…”

“…Eestis on üldiselt künnapuude tervislik seisund parem kui harilikul jalakal, mida kinnitab ka 2014-2016 aastatel tehtud võrdlev puude tervisliku seisundi analüüs (Jürisoo et al, 2019). Sama tulemus on saadud ka Loode-Venemaal Peterburis (Jürisoo et al, 2021a) ja Poolas (Łakomy et al, 2016). Sama võib kaudselt kinnitada ka see, et iga üheteistkümnes hariliku jalaka hinnatud puu oli nakatunud jalakasurmaga, künnapuude puhul oli jalakasurmaga nakatunud vaid iga 37. puu (tabel 3).…”

Lisaks tuleb otsida haigusele vähem vastuvõtlikke isendeid ja paljundada nende järglasi ka kohalike liikide hulgast (Martín et al, 2009).…”

This review provides an overview of and describes the current situation of Dutch elm disease (DED), which is one of the most devastating diseases for elms worldwide and in Estonia. It is known that in Estonia DED’s agent Ophiostoma ulmi has been damaging elms since the 1930s. Today a new species Ophiostoma novo-ulmi is considered to be an agent of DED. Since 2013 the current epidemic has been recorded in most of the counties of Estonia. The both known DED agents, Ophiostoma novo-ulmi subsp. novo-ulmi and O. novo-ulmi subsp. americana were molecularly detected on Ulmus spp. Additionally, one hybrid pathogen of the subspecies (americana x novo-ulmi) was identified in northern Estonia. Also, the health status of elms and the potential vector agents of the pathogen are discussed and recommendations for disease management are provided.

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