Gum and resin bearing tree species were one of the very important resources in Ethiopia. Particularly, Borana pastoralists used these as a source income generation for their livelihoods. However, resource was declining over time due to different natural human made problems. Therefore, it is study its future sustainability through soil seed bank, germinations, vegetative propagations analyzing r...

The maximum specific hydraulic conductivity (k(max)) of a plant sample is a measure of the ability of a plants' vascular system to transport water and dissolved nutrients under optimum conditions. Precise measurements of k(max) are needed in comparative studies of hydraulic conductivity, as well as for measuring the formation and repair of xylem embolisms. Unstable measurements of k(max) are a ...

Prior efforts to incorporate bark or bark extracts into composites have met with only limited success because of poor performance relative to existing products and/or economic barriers stemming from high levels of processing. We are currently investigating applications for southern yellow pine (SYP) bark that require intermediate levels of processing, one being the use of carefully ground and c...

The health, sustainability, and commercial viability of eastern black walnut (Juglans nigra) are currently under threat from thousand cankers disease. The disease is caused by an invasive bark beetle species, the walnut twig beetle (Pityophthorus juglandis), and its associated fungal pathogen (Geosmithia morbida). Range expansion of the beetle and pathogen has likely been facilitated by transpo...

reported that the decline in forest growth could lead to annual US timber market losses from $2.3 billion to $3.8 billion. [1] Governments and the private sector also spend substantial amounts on research and development of technologies to monitor, detect, and control invasive pests. Annual expenditures by the US federal government on all agricultural pests increased from $500 million in the mi...
