Robinia Pseudoacacia L

Abstract Robinia pseudoacacia is one of the most problematic invasive alien species in Japan. Information on genetic diversity and population structure is urgently required in order to generate effective management strategies. To assist such efforts we have identified five chloroplast microsatellite (cpSSR) markers for R. pseudoacacia by amplifying noncording regions of chloroplast DNA (cpDNA) using universal chloroplast primers. Among 857 individuals these cpSSR markers showed substantial polymorphism, with three to eight alleles per locus and gene diversity ranging from 0.387 to 0.713. These cpSSR makers will be useful for analyzing maternal lineages and population genetic structure of R. pseudo - acacia.

Abstract The black locust Robinia pseudoacacia (Robinieae, Fabaceae) is a common invasive riparian tree in Japan. There are less effective management strategies to remove the tree from the riparian area because of its quickly established high population. We investigated the expansion patterns of R. pseudoacacia through sympatric (i.e. between high- and low-water channel (HWC/LWC) within a study site) and allopatric (i.e. along river corridor) dispersal in the Tama River (Tokyo, Japan). Four microsatellites were used to examine the effects of gene flow on six populations in three sites. These subpopulations showed small genetic distance (i.e. no barrier or slightly limited) and genetically mixed population structure. It indicated that both sympatric and allopatric dispersals were active. Many migrants were younger individuals (i.e. <5 years old) and were found in the LWC area. Thus, the LWC could receive more migrants than the HWC through both types of dispersals. In addition, our age and genetic structure analyses reveal that recruited individuals likely settled immediately after the clearing project of R. pseudoacacia through sympatric dispersal. It appears that the migration by allopatric dispersal occurred following this. For the effective management of R. pseudoacacia, migrants should be removed regularly following initial removal of invaders during site restoration.

New Reservoir

Wood is one of the most highly valued materials in enology since the chemical composition and sensorial properties of wine change significantly when in contact with it. The need for wood in cooperage and the concern of enologists in their search for new materials to endow their wines with a special personality has generated interest in the use of other Quercus genus materials different from the traditional ones (Q. petraea, Q. robur and Q. alba) and even other wood genera. Thereby, species from same genera such as Q. pyrenaica Willd., Q. faginea Lam., Q. humboldtti Bonpl., Q. oocarpa Liebm., Q. stellata Wangenh, Q. frainetto Ten., Q. lyrata Walt., Q. bicolor Willd. and other genera such as Castanea sativa Mill. (chestnut), Robinia pseudoacacia L. (false acacia), Prunus avium L. and P. cereaus L. (cherry), Fraxinus excelsior L. (European ash) and F. americana L. (American ash) have been studied with the aim of discovering whether they could be a new reservoir of wood for cooperage. This review aims to summarize the characterization of tannin and low molecular weight phenol compositions of these alternative woods for enology in their different cooperage stages and compare them to traditional oak woods, as both are essential to proposing their use in cooperage for aging wine.

Abstract Roadsides can be vectors for tree invasion within grasslands by bisecting landscapes and facilitating propagule spread to interior habitat. Current invasive tree management in North America’s Great Plains focuses on reducing on-site (i.e., interior habitat) vulnerability through on-site prevention and eradication, but invasive tree management of surrounding areas known to serve as invasion vectors, such as roadsides and public rights-of-ways, is sporadic. We surveyed roadsides for invasive tree propagule sources in a southeastern Nebraska grassland landscape to determine how much of the surrounding landscape is potentially vulnerable to roadside invasion, and by which species, and thereby, provide insights into the locations and forms of future landcover change. Invasive tree species were widespread in roadsides. Given modest seed dispersal distances of 100-200 m, our results show that roadsides have potential to serve as major sources of grassland exposure to tree invasion, compromising up to 44% of grasslands in the Denton Hills. Under these dispersal distances, funds spent removing trees on grassland properties may have little impact on the landscape’s overall vulnerability, due to exposure driven by roadside propagule sources. A key implication from this study is that roadsides, while often neglected from management, represent an important component of integrated management strategies for reducing grassland vulnerability to tree invasion.

Due to their strong renewal power, the invasive tree species are spreading rapidly, especially in abandoned agricultural and forest areas and along traffic routes and water courses. One way of their restriction is the promotion of their use. In our research, we investigated surface finishing of wood of five selected invasive species in Slovenia, Box elder (Acer negundo L.), Black locust (Robinia pseudoacacia L.), Horse-chestnut (Aesculus hippocastanum L.), Honey locust (Gleditsia triacanthos L.) and Chinese sumac (Ailanthus altissima (Mill.) Swingle), and compared it with the finishing of the European beech (Fagus sylvatica L.) wood. For coatings, we selected one-component waterborne finish on acrylate-polyurethane basis, one-component solventborne finish on polyurethane basis and tung oil as a natural finish. Several surface properties were investigated. We proved that surface hardness, resistance to impact and adhesion were very much related to interactions between the coating and the substrate, while resistance to cold liquids was only dependant on the type of the finish. It was also shown that, in general, finishing of woods of selected invasive tree species was not problematic. The only exception was Black locust wood on which tung oil cured very slowly.

To develop measures for the restoration of historic plantations and landscapes of the Nataliivskyi Park (Kharkiv region, Ukraine), the investigations of taxonomic composition and distribution of woody plant taxa, as well as structure of different landscape areas, were carried out in 2018–2019. The recent studies were realized according to the same protocol applied in 1997 by Y. Klymenko, and taking into account previously published data.In 1939, the dendroflora of the Nataliivskyi Park comprised about 100 taxa. Later, the number of taxa significantly decreased, and in 1950 the park’s dendroflora comprised only about 40 taxa. In 1997 there were 74 taxa reported. Since 1997, the taxonomic composition of the park’s dendroflora has been enriched by ten taxa and is currently represented by 84 taxa. Simultaneously, the number of valuable plants in the plantations decreased (only one or two plants represent some such taxa). Due to a bark beetle attack on drought-weakened trees of Picea abies and P. pungens, most of them withered. The area of allotments with Pinus sylvestris and Quercus robur remained almost the same, which indicates their stability. The area of allotments with the domination of such naturalized introducers as Acer negundo and Robinia pseudoacacia and the area of allotments with the domination of neither taxa have increased. In the landscapes, the redistribution of the types of areas appeared. The forest type of landscape became predominant, while the meadow type of landscape has almost disappeared.Hence, to restore historical plantings and landscapes, it is necessary to re-cultivate taxa represented here during the park’s heyday and remove invasive tree species. Although cuttings in protected areas are currently prohibited, our investigations showed that they might help preserve such valuable territories as Nataliivskyi Park.
