General view of the plot irrigated by treated wastewater since 2005 in the treatment plant El-Hamma and cultivated by Eucalyptus camaldulensis aged around ten years

The aim of this work was  to evaluate the effect of treated wastewater short and long-term irrigation on essential oil composition from E. camaldulensis Dehn in order to detect allelopathic impacts on seed germination and seedling growth of Amaranthus hybridus L, Chenopodium album L, Echinochloa crus-galli (L) Beauv and Lolium perenne L as important weeds on many crops.

Artisanal value of wood and roots of E.loxophleba of El Hanya Arboretum - Sousse

Roots of Eucalyptus loxophleba and Specimens collected

In Tunisia, handicrafts based on local wood are mostly from olive wood. Due to its physical, mechanical and aesthetic qualities, olive wood is highly sought and appreciated by artisans and buyers. In front of the growing demand for this wood, local people do not hesitate to resort to illicit cuts to satisfy the needs of the market. The objective of this study is to search for forest species offering wood qualities that rival those of olive wood and that can be valorized for artisanal use.
