Developing protocols for the collection and valuation of wild native seed from the Hudson Bay Lowland.
Native species are being more commonly used and often even mandated in restoration projects. However, commercial seed sources are often unavailable or not of a suitable provenance. Collecting seed from wild sources is an alternative, but it can be challenging. The objectives of this study were to: 1...

The objectives of this study were to: 1) identify key attributes that influence the value of seed and to evaluate and quantify these differences for 57 native species with potential for restoration in subarctic Ontario; 2) determine if fertilizers could increase the seed yield of wild species with a low seed output; 3) determine and compile simple and effective protocols for the collection, processing, storage, and germination of 60 wild species native to northeastern Ontario. Field studies were conducted at De Beers’ Victor diamond mine, located in the Hudson Bay Lowland in north-central Canada from 2014 to 2016. To complete the first objective, I evaluated the attributes that affect the time and cost of using wild seeds from upland native plants. Taking into account the regional abundance of species, collection obstacles, requirements for identification, ease of processing and storing seeds, and propagation effort, I ranked the results for each species within each attribute. Each category provided a relative value reflective of the effort required to collect, process, store, and propagate seed of a given species.

These relative seed values can also be used to determine seed prices for a variety of projects and locations. For my second objective, I fertilized wild populations of American vetch (Vicia americana) and silverweed (Potentilla anserina). These herbaceous upland species may be useful in reclamation, but had low seed yields in 2014.
