Why do inventory mixes change?

Our inventory mixes can vary slightly within the same year or between years. Each of our inventory mixes are reviewed annually to assess any changes in production cost and the effectiveness of species in seed mixes that are created with particular goals or outcomes. Occasionally, species that were selected when creating an inventory mix may become unavailable due to crop failure or high demand. If there is a species unavailable, we will make a substitution that closely relates to the missing species and that would conform with the goals of the particular inventory mix.
