The problem is particularly notable with a suite of exotic grasses in the Bromus genus in the arid and semiarid regions that dominate the western United States, which extend from the dry basins near the Sierra and Cascade Ranges across the Intermountain Region and Rockies to about 105° longitude. This genus includes approximately 150 species that have a wide range of invasive and non-invasive tendencies in their home ranges and in North America. Bromus species that became invasive upon introduction to North America in the late 1800’s, such as Bromus tectorum and B. rubens, have since became the dominant cover on millions of hectares. Here, millenia of ecosystem development led to landscapes that would otherwise be dominated by perennial shrubs, herbs, and biotic soil crusts that were able to persist in spite of variable and scarce precipitation. This native ecosystem resilience is increasingly coveted by land owners and managers as more hectares lose their resistance to Bromus grasses and similar exotics and | | 出版日期 | Book 2016 | | 关键词 | bromus; ecosystems; exotic grasses; epidemic disease; soilborne pathogen; geomorphology | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-24930-8 | | isbn_softcover | 978-3-319-79701-4 | | isbn_ebook | 978-3-319-24930-8Series ISSN 0172-6161 Series E-ISSN 2512-5559 | | issn_series | 0172-6161 | | copyright | Springer International Publishing Switzerland 2016 |
