We soon concluded that tall grass prairie was the most endangered ecosystem in the Province, as all but a very small percentage had been ploughed.Where to start? I wrote to all the agricultural representatives and to all the agencies and individuals we could think of, to ask them whether they knew of any tall grass prairie sites. We had a good response and during the ensuing summer we attempted to visit all the suggested sites, be they road allowances, cemetaries, farmer's fields, community pastures etc. We had a short list of candidate species that we felt should be present. Many of the species no longer existed, or had no tall grass prairie, but one Hutterite colony had a magnificent quarter section of prairie which we decided to inventory. You can imagine our dismay when we returned to carry out our plant species inventory, the whole lot had been ploughed.
