This objective of this study is to investigate how false brome, Brachypodium sylvaticum newly invasive plant in the Northwest region in USA is distributed and spread at an experimental forest, H.J. Andrews Forest. I checked out the distribution of false brome at diverse habitat including roads, junctions between roads, streams and tributaries from the roads and stream in H.J. Andrews Forest. False brome were distributed along roads and streams in the Andrews Forest, and invaded into interiors between road and stream networks. This study showed that the invasion of false brome can be accelerated by road and streams networks over years and exotic plants like false brome can have a possibility to establish in a conserved area of H.J. Andrews Forest.
