Oldr ch Hak SPU 1106 Poor pollen quality at pollination time may be one of the principal factors responsible for the failure of low-elevation orchards to produce sufficient quantities of viable seed. To date, all assessments of pollen quality were based entirely on vitro testing using pollen germination. These assessments should be interpreted as only an indication of pollen fertility. In this project, the actual fertility of low-elevation males is being confirmed through control pollinations of females in natural stands. Similarly, the level of fertility of low-elevation females is not known and is being examined through control pollinations using high-quality pollen collected from natural stands. Trials at a low-elevation seed orchard (Mount Newton) and in natural stands at high elevation (Mount Washington and Jordan River high elevation) have been completed and the results published in the 2004/2005 Project Report. The results indicate that low-elevation yellow-cedar seed orchards are capable of producing viable seed. This is contrary to earlier reports that low-elevation seed orchards established on Vancouver Island are not capable of doing so. Given the importance of the location and management of yellow-cedar breeding and seed orchards, recommendations for their establishment should be based on more than oneyear data. Furthermore, difficulties encountered during the first project with environmental conditions and bears P R O J E C T R E P O R T 2 0 0 6 / 2 0 0 7 introduced several factors that may influence the results of the trial to a certain degree. A follow-up project at Mt. Newton seed orchard (low elevation) and Mt. Washington (high elevation) was therefore established in 2004 to deal with the above problems and to confirm the results of the first project through re-testing. An additional site at Jordan River low elevation was included in the new project because it has produced good quality pollen in past trials and has a good potential to produce viable seed. Control pollinations at all the above sites were completed in spring 2005. Cones were collected and seed was extracted in fall 2006. Data will be analyzed, and the final results will be reported in spring 2007. .2.
