Book Description
The oak tree was a boon companion as humans expanded their presence across much of the globe. While oak woodlands (Quercus spp.) come today in stunningly diverse forms, the stately dehesas of Spain and the dramatic oak-dominated ranchlands of California are working landscapes where cultivation and manipulation for a couple of millennia have shaped Mediterranean-type ecosystems into a profoundly modified yet productive environment that is sought-after by every manner of species. The grazing of wildlife and livestock in oak woodlands yields a remarkable plant and animal biodiversity, creating a mosaic of habitats and visually pleasing savannas. Added products unique to Spain such as Iberian pigs and cork, and in California multiple landowner benefits, include valued ecosystem services that allow owners, visitors, and conservation supporters to experience the benefits of woodland life. With its 15 chapters a decade in the making, this handsomely illustrated book covers key topics in oak woodland policy, ecology, and management in Spain and California, presenting new research results and reviewing an existing expert literature.

Book Description
Breeds of livestock on British farms are changing constantly. New breeds emerge, foreign breeds are imported, while some native breeds lose popularity and become endangered. More than half the native breeds in Britain are rare and potentially threatened with extinction, yet they are an integral part of our history and heritage. Many of them are distinctive animals, and some possess special characteristics that could be of value to the livestock industry. A return to more traditional values was seen towards the end of the twentieth century, and this will serve to enhance the value of native breeds.
