Juglans ailantifolia caused by the fungus "Sirococcus clavigignenti-juglandacearum". This has led to its being planted as a replacement for butternuts in North America. The two species hybridise readily; the resulting hybrid "Juglans x bixbyi" (otherwise known as "J. cinerea x ailantifolia" or 'buartnut') is also resistant to canker and is likewise planted as a replacement for butternuts. Japanese walnut is distinguished from butternut by its larger leaves and round (not oval) nuts. Prospect Rock Permaculture in Vermont has been backcrossing buartnuts with native butternuts, resulting in 'butterbuarts', which will most likely bear greater resemblance to the butternut parentage, although may also be
Tree-kangaroo They are expert leapers; downward jumps from one tree to another have been recorded and they have the extraordinary ability to jump to the ground from or more without being hurt. The main diet of the tree-kangaroo is leaves and fruit that it gathers from the trees, but occasionally scavenged from the ground. Tree-kangaroos will also eat grains, flour, various nuts, sap and tree bark. Some captive tree-kangaroos (perhaps limited to New Guinea species) eat protein foods such as eggs, birds and snakes, making them omnivores. Little is known about the reproduction of tree-kangaroos in the wild. The only published
