The second full annual inventory of Indiana's forests reports more than 4.75 million acres of forest land with an average volume of more than 2,000 cubic feet per acre. Forest land is dominated by the white oak/red oak/hickory forest type, which occupies nearly a third of the total forest land area. Seventy-six percent of forest land consists of sawtimber, 16 percent contains poletimber, and 8 percent contains sapling/seedlings. The volume of growing stock on timberland has been rising since the 1980s and currently totals more than 8.5 billion cubic feet. The average annual net growth of growing stock on forest land from 2004 to 2008 is approximately 312 million cubic feet per year. This report includes additional information on forest attributes, land use change, carbon, timber products, forest health, and statistics and quality assurance of data collection. AcknowledgmentsThe authors would like to thank the many individuals who contributed both to the inventory and analysis of Indiana's forest resources. Primary field crew and QA staff over the [2004][2005][2006][2007][2008] field inventory cycle included Gary Stachowicz, Dan Johnson, Mark Webb, Jason Stephens, Joey Gallion, Greg Yapp, Aaron Hawkins, Matt Goeke, Kasey Krouse, Lance Dye, Dominic Lewer, Will Smith, and Pete Koehler. Data management personnel included Gary Brand, Mark Hatfield, Jay Solomakos, and James Blehm. Report reviewers included Joey Gallion and Carl Hauser of Indiana's DNR.Cover: Autumn in the deciduous forest. Photo used with permission of Indiana Dept. of Natural Resources.
Australian Native Plants provides a comprehensive guide to the horticulture of our native plants. Based on nearly 50 years of experience at Kings Park and Botanic Garden in Perth, the book describes the necessary growing conditions for mainly Western Australian native plants and covers some of the more technical aspects such as plant propagation and grafting, the use and benefits of tissue culture, methods of seed collection and storage, and the role of smoke in improving germination. Western Australia is home to about five per cent of the world’s vascular plants and contains Australia’s only terrestrial ‘biodiversity hotspot’. Written by experts with an in-depth knowledge of how to grow these plants outside their natural habitat, Australian Native Plants provides the more technically minded professional or enthusiast with information based on decades of research, experimentation and application. It aims to encourage the growing of Australian plants so that they can be used more widely and contribute to interesting, attractive and diverse private gardens and public landscapes in a changing environment.
