Yellow-cedar population study

Project number: EP 1012.01

District: Selkirk Forest District

Objectives

• To determine the extent and pattern of genetic variability in yellow-cedar between populations to help guide seed transfer
• To determine the feasibility of planting yellow-cedar in the interior wetbelt and to identify seed sources adapted to the interior

Treatment

30 rangewide populations yellow-cedar.

Layout

Randomized complete block with 12 blocks; 5-tree row plots per population per block.

History
