Steps Toward Butternut (Juglans Cinerea L.) Restoration, Sunshine L. Brosi Aug 2010

Steps Toward Butternut (Juglans Cinerea L.) Restoration, Sunshine L. Brosi

Doctoral Dissertations

Butternut (Juglans cinerea L.), a lesser-known relative of black walnut (Juglans nigra L.), is a native tree species beneficial for wildlife, valuable for timber, and part of the great diversity of species in the eastern forests of North America. Populations of butternut are being devastated by butternut canker disease, caused by the fungus Sirococcus clavigignenti-juglandacearum (V.M.G. Nair, Kostichka, & Kuntz), which is thought to be introduced to North America. The disease causes multiple branch and stem cankers that eventually girdle trees. Small population sizes, lack of sprouting, and shade intolerance exacerbates the disease and results in permanent losses of butternut …


Can Lessons From The Community Rainforest Reforestation Program In Eastern Australia Be Learned?, Jerome K. Vanclay Jan 2010

Can Lessons From The Community Rainforest Reforestation Program In Eastern Australia Be Learned?, Jerome K. Vanclay

Professor Jerome K Vanclay

The Community Rainforest Reforestation Program (1993-2000) was an attempt to create healthy vegetated catchments that maximize wood production, environmental protection and employment in eastern Australia. Despite a AUD10 million outlay, these goals were not fulfilled, because of limited resources and continually changing circumstances (goals, staff, institutions) that hampered the efforts of both researchers and coordinators. Both technical and managerial lessons need to be learned: blanket guidelines are rarely helpful because species, nutrition and silviculture need to be matched to each site; vigour, provenance and nutrition of nursery stock is critical to plantation success; health surveillance should not be overlooked; early …
