Book excerpt: Describes alternative approaches to controlling the damage black bears cause during the spring when they strip bark to eat the newly formed wood underneath. One bear might strip as many as 70 trees in a day. The trees will be damaged and may be killed if the bark is stripped all the way around the tree, girdling it. Bears appear to strip the most vigorous trees, preferring stands that have been thinned, or those where urea fertilizer has been applied. Bears also appear to prefer trees with a high concentration of sugars relative to the concentration of terpenes. Pruning decreases the sugar-to-terpene ratio, reducing the likelihood that trees will be stripped by bears. Bears generally quit stripping trees once other foods become available during the late spring or early summer. One approach to reducing damage has been to provide supplemental feed (pellets resembling dog food) in stands being damaged by bears. In one study, damage was just one-fifth as much in stands with feeders as in stands without feeders. Killing bears in areas where trees are being stripped can also reduce damage. Other approaches, such as relocation, contraception or sterilization, or repellents, are not generally practical for protecting forest plantations.

Download or read book Vertebrate Pests in Agriculture written by S. Sridhara and published by Scientific Publishers. This book was released on 2016-06-01 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertebrate pests cause considerable damage to environment, agriculture and biodiversity apart from transmitting diseases. The problem is more pronounced in tropical Asia and Africa with non-human primates, elephants, several species of ungulates, rodents, frugivorous and grainivorous birds causing agricultural losses. In Europe and America the damage is due to carnivore predation on livestock, bird damage in cereal crops and rodent problem in urban and agricultural situations. Although there are several excellent books on rodent pest management both in India and at global level, there is a conspicuous lacuna of published books on vertebrate pest management. Even the few publications on the subject mostly deal with birds, rodents, bears, rabbits, foxes, etc because they are written by Americans or Britishers. Because their emphasis is on the problem prevalent in their countries and evaluation of management options available to them. In contrast the problem in tropics especially in India is unique. Rodents of course, are the most destructive. But what rodents do over twelve months of year is matched by a few nights of devastating crop raids by elephants or week long foraging by monkeys. Sporadic and localized damage is inflicted by several species of birds, bats, wild boar, blue bull, bears, hares, peacock etc. The damage is sometimes so high, it is impossible for a subsistence farmer to accept stoically the loss of his entire food source over a couple of days and nights. However, his options are limited in view of conservations and protection status enjoyed by some of these animals. The problem is compounded by religious sentiments associated with a few of them. This book is an attempt to find an acceptable solution to the problem of crop losses of these less studied but economically important groups of vertebrate pests. Sincere efforts have gone into formulation of recommendations keeping in mind the biological needs of vertebrate pests, their conservation status and suffering of the poor farmer. Many a time the sympathies deservedly go to the speechless marauders of crops as it is man who has shrunk, degraded and destroyed their habitat, deprived them of their natural source of food. There are no choices for vertebrate pests but raid the crops in their range but we, humans have several to survive. The book is an attempt to understand this dilemma.

Available in PDF, EPUB and Kindle. Book excerpt: The introductory course in natural resources is broader and more diverse than ever. Today's students need to know how to manage forest, wildlife, watershed, and range resources in a variety of environments and serving the needs of myriad stakeholders. To that end, Chad Dawson has built on the foundation established by him and the late John Hendee to bring Introduction to Forests and Renewable Resources thoroughly up to date. The Ninth Edition has been reorganized to better address content—for example, policy and the differences between managing federal, state, and private land—that applies to all resources. While forests continue to be emphasized, more coverage is provided to other resources and to achieving management goals for multiple resources when considering topics like fire and recreation.
