Table 2 Paludification scores for static and dynamic stand scale factors

From: Forecasting the development of boreal paludified forests in response to climate change: a case study using Ontario ecosite classification

Surficial deposit (D) Soil texture (T) Humus form (H) Soil organic layer thickness (SOL) Moisture regime (M) Overstorey (O)

  1. Each static and dynamic factor was divided into classes, each of which was attributed a score related to its paludification “power”; 0 = null “power”, 1 = low “power”, 5 = high “power”. Adding up the score of each factor, gives a Paludification Index that estimates the liability of each stand to paludification.
  2. 1According to Sims and Baldwin (1996).
  3. 2In cm. In our paludification index, we used the median value of each class.
  4. 3According to Sims et al. (1989).
