Info

common introduced species include birds like the European starling and house sparrow. Many of the grass species growing in the shade of the cottonwoods are also introduced. The most common of these introduced grasses are smooth brome and crested wheatgrass. Unfortunately, several non-native weeds also thrive in the river valley. One example is leafy spurge, a noxious weed that has been spreading rapidly over the floodplain. Other plant invasive species include Canada thistle and spotted knapweed. Not only do these invasive species out-compete native species, leading to their loss, but they also affect our aesthetic landscape and are very costly and time consuming to remove. Stewardship Tip: Always clean off your shoes, bike tires, and boats when travelling from one ecosystem to another, to prevent the spread and introduction of non-native species to a natural area. It is also important to stay on established trails. Off-road vehicles are not permitted in City of Lethbridge parks, in order to reduce damage to the environment and minimize the spread of invasive plant seeds. Conclusion The residents of Lethbridge are fortunate that so much of the Oldman River valley in the City has been preserved in a natural or semi-natural state. It is important that this valuable heritage be conserved in the future. We hope this booklet has helped you to appreciate the valley, from its past human history and geological record, to the present-day assemblage of plant and animals. We ask that you treat the land and its wild residents with respect so that they will be here for generations to come, and hope that you visit the area often. 30 Asparagus Wormwood, Sarah Underwood Leafy Spurge Hawkmoth Caterpillar, L.
