The pacific yew that is most likely found in the province of british colombia. Yews can grow in diverse conditions depending the species. Generally, they require partial sun and well-drained soil. They are susceptible to diseases such as root rot caused by overly wet soil conditions. However, pests like black vine weevil and mites also affect the shrub. Yew is extremely shade tolerant, nevertheless, growth within mature yew woodland is rare in britain and across europe. The replacement of individual trees depends entirely on the development of a shrubby sere in gaps left by dead yews but primarily around the edge of existing woodland. The yew is the most shade tolerant gymnosperm found.
