In 2017 Stuart and Lea relocated and measured 19 individuals of the 381 seedlings originally found. These plants had 1-4 leaves; the longest leaf was 32 cm. It should be interesting to see which individuals are hanging on!
Caroline Ridley established this experiment to compare fitness (recruitment and survival) of seeds originating from individuals with parents from three different backgrounds: 1. both from a large remnant population, 2. both from a small remnant population (not rescued), and 3. one from a large population and one from a small population (genetically rescued). Caroline sowed achenes in an experimental plot at Hegg Lake WMA and marked seedlings with colored toothpicks in May 2009.
Start year: 2008
Site: exPt 4 at Hegg Lake WMA
Overlaps with: crossing experiments qGen1, qGen2, qGen3 & recruitment experiment; INB1
