Forage Production
Forages are a key consideration in any silvopasture operation. In the context of Christmas tree silvopastures in the East Kootenay region, they have direct relevance to livestock production potential, and also are a variable of consideration for land use decisions and wildlife enhancement.
The Kootenay/Boundary Land Use Plan recommends periodic entries of prescribed burning, thinning and partial-cutting to maintain open forest conditions and rangeland values. And, ecosystem restoration projects are currently underway in several areas of the region. To date however, no projects have compared the effects of different types of Christmas tree management systems on forage production.
One of the objectives of this operational trial was to demonstrate that a silvopasture system will benefit forage production, improve forage quality and increase the grazable area of a pasture. Treatments (with untreated controls) were installed, representing the effect of the silvopasture management system on plant communities that are dominated by native and domestic vegetation, respectively. The first post-treatment monitoring took place in 2013. Preliminary results have shown that forage cover, production and species diversity increases with decreasing overstory, under a silvopasture scheme. The long-term suitability of silvopastures to contribute as an ecosystem restoration / forage enhancement land management tool will require additional monitoring to see if these trends hold.
Economics
A production system cost-benefit analysis has been developed based on the project results with regional Christmas tree production and market information. The production model, which Kootenay Tree Farms has evolved is based on years of practice in the East Kootenay region, is rooted in the philosophy of ‘doing it the best way for the greatest return’. Underlying this management concept is a goal of providing agroforestry management options to producers which enhance producer and ecological sustainability, while complementing larger landscape-level management strategies.
The review gathered economic and production data for a hypothetical Christmas tree enterprise in the East Kootenay region of BC. It was undertaken primarily for Christmas tree producers and those potentially interested in becoming a Christmas tree producers, and was designed to provide a starting point for them to assess the potential of a Christmas tree enterprise. The analysis provides a beginning economic assessment from which to consider one's own notions about production and economic factors, and the potentials and pitfalls of a Christmas tree enterprise in this region.
Disease Control
Christmas trees have been pruned for a long time to improve tree quality but never to control disease. In this project component, Kootenay Tree Farms investigated different management methods to control or eliminate Rhabdocline disease in Douglas-fir Christmas trees. The results indicate that techniques that build the soil duff layer, improve soil fertility, or reduce surface temperatures or humidity can contribute to significant reductions in disease levels in the trees. Using pruning and tree thinning methods that improve air flow through the production site, together with practices that improve the health of the trees are key.
