It is a wood species that can be expressed in many ways thanks to modern surface treatments and new technology. The Exhibition explores the themes of real, fake and craftsmanship. Pine logs were used to represent real materials, but they also symbolised the process of producing future materials for interior design.
Here at Dwell, we love natural materials—and wood is no exception. Whether it's sourced from sustainable forests or reclaimed from existing buildings, it can be painted, stained, or left all natural. Because of these various treatment options, it can be particularly difficult—if not nearly impossible!
Pine wilt disease PWD constitutes a serious threat to pine forests. Since development depends on temperature and drought, there is a concern that future climate change could lead to the spread of PWD infections. We evaluated the risk of PWD in 21 susceptible Pinus species on a global scale. For future climate conditions, we compared the difference in PWD risks among four different representative concentration pathways RCPs 2.
Pines are the shrub and tree species that belong to the genus Pinus. These are evergreen coniferswhich have bundles of needles rather than the broad leaves commonly found on deciduous trees.

Intraspecific variation in morphometry of pine wood nematodes Bursaphelenchus xylophilus and B. The body length of male and female B. All morphometric characters in B. Outbreaks of pine wilt disease in East Asian countries are caused by the exotic pine wood nematode, Bursaphelenchus xylophilus Steiner et Buhrer Nickle, which was previously endemic to North America.
It previously had the scientific names Bursaphelenchus lignicolous and Aphelenchoides xylophilus. Infestation of pine trees by pine wood nematodes causes a condition called pine wilt disease, and is often fatal to the tree. There have been extensive tree deaths in all countries where pine wilt has been recorded.
