I remember explaining to the biologist that I rode my horses in the wheat fields most often, but for fun I would often hop on bareback in that pasture with just a halter and a rope lead and canter in the trees, sometimes grabbing an overhead tree branch and swinging off. Cattle, like the bison before them, graze the range in a way that leaves varying levels of grass in different areas — some grass will remain tall and other areas will be grazed to almost nothing — fertilized by manure which provides nutrients to the soil and many insects, which, in turn, feed many birds. Carefully managed cattle grazing conserves both the grasslands and the habitat for many species at risk. Invasive species are non-native animals or plants introduced to a new environment, either intentionally (for example for fur production) or unintentionally (e.g., seed dispersal, stowaway rats), which cause a detrimental impact to one or more native species or habitats. Canadian grasslands evolved under this cycle of growth and cutting back, and to this day native grasslands do best when they are periodically cut back. Municipal assets at risk include: Green infrastructure. Unlike native species, invasive species do not naturally occur in that area.
