Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.
An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Other Uses
The husk of the fruit is used as a source of tannins[331 ]. The wood is used for making fancy furniture[331 ]. We do not have any more information for this species, but the general description for the wood of the tropical members of this genus is as follows:- The heartwood is chocolate-brown and generally darker than the North American black walnut (Juglans nigra), sometimes with a purplish cast; it is sharply demarcated from the whitish sapwood. The texture is rather coarse; the grain is straight to irregular; luster is high; odour and taste are mild but distinctive. The wood dries very slowly, wet zones persist, and severe honeycombing and collapse may occur in stock thicker than 10cm x 10cm. The wood works well, cutting cleanly with hand and machine tools and taking an excellent finish. It also peels and slices readily but the veneers are also reported to dry slowly. It is used for decorative veneers, furniture, cabinet work, interior finish, and other applications similar to the North American black walnut[316 ].
