This article investigates the quality of the machining surface of the five most common invasive tree species in Slovenia, i.e., black locust (Robinia pseudoacacia L.), boxelder maple (Acer negundo L.), horse chestnut (Aesculus hippocastanum), honey locust (Gleditsia triacanthos) and tree of heaven (Ailanthus altissima). The machining tests were made according to the American Society for Testing and Materials (ASTM) D1666-17 standard, where the quality of the surfaces after planing, routing and turning were evaluated with visual assessment, and the area and profile roughness parameters were also determined on selected specimens. The results showed that boxelder maple, horse chestnut and honey locust can be machined very well in all the studied operations, with the best results in routing and a little less good by turning, whereas the tree of heaven had the best quality in planing, and the worst by turning. Among all studied tree species, the black locust had the worst quality in planing, but the quality at routing was very similar to other tested species. The research also showed that there is little or no significant relationship between the qualities of the various types of machining for tested tree species.

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.

Verticillium Albo Atrum

Extensive, unprecedented wilt and mortality of the highly invasive tree-of-heaven (Ailanthus altissima) occurred recently within mixed-hardwood forests in south-central Pennsylvania. Until this study, the cause of the epidemic was unknown. Verticillium albo-atrum was consistently isolated from symptomatic Ailanthus seedlings and trees in areas having high levels of mortality, whereas V. dahliae was isolated from small scattered patches of diseased Ailanthus. Inoculations of potted Ailanthus seedlings in the greenhouse, as well as canopy trees in the field, revealed that both V. albo-atrum and V. dahliae were capable of infecting Ailanthus, but V. albo-atrum was more pathogenic. All Ailanthus seedlings and canopy trees inoculated with V. albo-atrum died within 3 months. In contrast, Ailanthus seedlings and canopy trees inoculated with V. dahliae became symptomatic, but 84% were still living 1 year following inoculation. We conclude that the major cause of Ailanthus wilt within forests of south-central Pennsylvania is V. albo-atrum. Pending further studies, including risk analysis, V. albo-atrum may be considered as a possible biocontrol agent for invasive Ailanthus.

In this case study, we used point mapping data to evaluate long-term treatment of invasive tree-of-heaven (Ailanthus altissima). This study at the Buffalo National River included 21 project areas ranging in size from 0.02 to 11.3 ha and spanned five to eight years depending on the site. The control techniques varied depending on the year and included the application of herbicide, which also varied over the course of the study and included imazapyr, triclopyr, and triclopyr+fluroxypyr. Treatments during the first year reduced local A. altissima populations by an average of 66%. Long-term repeated treatments led to decreases of at least 90% in 70% of the project areas and at least 73% in 95% of the project areas. Only one project area was found to support no plants during the final treatment year. A. altissima increased at most project areas during an unusually wet year and was more likely to increase than decrease in intervals > 1 year with no treatment. Over the temporal and spatial scales of this case study, we observed high levels of control that will likely meet the specified levels and ecological benefits required in many similar efforts. Land managers must, however, make a long-term commitment of resources to achieve lasting control of this invasive species.
