![]() ![]() SRC crops are typically planted during the spring season where they are then left to grow over the first year. The resulting energy crop fuels may be utilized within a wide range of bioenergy systems to generate heat or power, from domestic to industrial scale. These are well suited for growth on lands with a wide range of soil classifications and can also be successfully produced on marginal/reclaimed lands. ![]() Predominant SRC energy crop species include willow and poplar. Mirjam Röder, Andrew Welfle, in Managing Global Warming, 2019 12.7.1 Energy crops: Short rotation coppices In addition to the use of naturally occurring species and woodland, several million hectares of plantation, often comprising species of eucalyptus, have been established. In contrast coppice has remained an important system of management in tropical areas where demand for fuel and small-diameter wood, for building purposes is still high. However, during the last two to three decades there has been a resurgence of interest in coppice grown on short rotations, primarily for use as a biofuel although longer rotations are used for the production of pulp woods. There are still about 50 million ha of coppice within the industrialized nations but only 60% of this is classified as utilizable ( Table 1). However, in these regions the art of coppice management has been in decline for 100–200 years and many woodlands have been transformed to high forest. In the developed world elaborate forms of coppice management to control yield, and provide a sustainable supply of small wood and large timber, reached their zenith prior to industrialization when alternative fuels, building materials, and chemicals became more readily available. Repeated felling produces the multistemmed stools typical of coppice woodland. At its simplest, woodland comprising single-stemmed trees which have grown from seed are clear-felled and allowed to regrow. The basic method is simple and relies on the ability of many trees to regrow from the stumps remaining after felling. The management of woodlands as coppice has a long history and archeological evidence indicates that the process was used in prehistoric times. Coppice is a word that is used by foresters to cover many things including: a type of woodland consisting of trees that are periodically cut the multistemmed trees that occur in such woodlands the process of felling the trees and the production of new shoots by recently cut stools. ![]()
