Bee Flat Canyon A case study in producing functionally diverse seed mixes using local source plant material.

The New Irvine Ranch Conservancy is a 501(c4) non-profit that manages open space within the 40,000 acre Irvine Natural National Landmarks. A large component of the Conservancy’s work is restoration of critical habitat. One of the flagship projects is a 84 acre sub-watershed restoration being implemented in one of the IRNL’s most ecologically valuable areas. The Bee Flat Canyon restoration, entering its fifth year, has succeeded in utilizing only locally sourced plant material for seed mixes and nursery plantings, the majority of which was provided by the Conservancy’s 12 acre seed farm. Here we will deconstruct the coastal sage scrub seed mix used for this restoration and examine total costs for plant materials per hectare, as well as the relationship between production costs associated with seeding, planting, maintenance, harvesting, processing, and general operations. In an effort to highlight general trends observed over five years of seed production, we will compare the costs of shrub, forb, and grass specific seed mixes. Using these examples, we will highlight variation in production costs, yield, and seed test data that have been observed between different functional types and how these differences affect our ability to produce seed mixes that are functionally diverse.
