This work presents the research carried out to determine the natural durability of reed from the Fertö region of Hungary against wood decay organisms. The final objective of this study is to obtain sufficient relevant data in order that the reed may be used as a constituent element in a viable and sustainable motorway noise barrier, which has been developed within the European research project, known by the acronym HOLIWOOD. The common reed grass (Phragmites australis, or Phragmites communis) is a large perennial grass of considerable size which grows in temperate and tropical wetland zones throughout the world. Its growth is expansive and it frequently invades wetlands where it competes with the native species and therefore requires regular removal so that an excess of organic material is not produced in the habitat. In addition, the invasion by this plant of polluted waters also appears to have a beneficial effect, so it can be used as a natural water purifier and thus has a potential use as a purification method for wetlands contaminated by agricultural practices. Due to the need for its periodic extraction its possible use as a construction material, although in a secondary role, gives it an added value for which further scientific study is required. In the absence of a reference Standard and being reed a lignocellulose material, the study of its natural durability has been based on the existing Standards for wood. The tests show that Hungarian reed has a high level of durability against some fungi and other wood decay organisms.
