A recently introduced non‐native annual grass, Ventenata dubia, is challenging previous conceptions of community resistance in forest mosaic communities in the Inland Northwest. However, little is known of the drivers and potential ecological impacts of this rapidly expanding species. Here we (1) identify abiotic and biotic habitat characteristics associated with the V. dubia invasion and examine how these differ between V. dubia and other problematic non‐native annual grasses, Bromus tectorum and Taeniatherum caput‐medusae; and (2) determine how burning influences relationships between V. dubia and plant community composition and structure to address potential impacts on Inland Northwest forest mosaic communities.

扩大入侵的范围：美国内陆西北部蓝山的Ventenata dubia及其与野火，环境和植物群落的关系

最近引进的非本地一年生草本植物Ventenata dubia挑战了内陆西北部森林马赛克群落先前的群落抗性观念。但是，对于这种迅速扩大的物种的驱动因素和潜在的生态影响知之甚少。在这里，我们（1）确定与V相关的非生物和生物栖息地特征。杜拜入侵并研究V之间的差异。水蚤和其他有问题的非原生一年生禾本科植物，旱雀麦和Taeniatherum人均-水母; （2）确定燃烧如何影响V之间的关系。 杜比亚 以及植物群落的组成和结构，以解决对西北内陆森林镶嵌群落的潜在影响。
