Download or read book Field Guide to the Autecology of Selected Crop Trees and Competitor Species in Northeastern Ontario written by R. W. Arnup and published by Timmins, Ont. : Northeast Science & Technology. This book was released on 1995 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual contains information on seven commercially important tree species and on 44 plant species that may compete with these crop tree species in northeastern Ontario. The introduction provides background information for the species comparison tables and species summaries that follow, and explains the format of the manual. The tables give information on each species' autecology in the context of the Forest Ecosystem Classification (FEC) system for northeastern Ontario. In addition, each potential competitor is evaluated with respect to their competitive effects and mechanisms, their response to disturbance and silvicultural treatments, and their potential value for wildlife. The crop tree species are evaluated with respect to their response to competition and their ability to respond to release. Line diagrams are included to aid in field recognition. The appendix contains a glossary and a key to FEC names and descriptions.
