Originally posted by Rense It looks great, thanks for sharing. So, the vegetation in this place is still dominated by native species? As far as I understood, many tallgrass prairies turned into something similar visually, but the species composition changed dramatically, due to the invasion of European and Asian plant species, amongst which quite a lot annual grass species.
In general you are correct. Most "Tall Grass" prairies are a mixture of exotics and natives here in N. America.
This prairie is different.
The difference is fire. For the last 100 years or so this particular land has been maintained by periodic burns natural and man made. When the Europeans came they stopped the great grassland fires that once were common and maintained the natural habitat. With roots 12 feet deep Big bluestem is much more fire, heat, cold and drought resistant than exotics but without fire exotics, given enough time, can take hold. This is what has happened on most so-called "tallgrass" prairies.
I once saw a core sample taken from this land. The sod depth was about 6 feet in this particular sample.
