Howie et al 2012: Laggs of Raised Bogs in Coastal British Columbia, Canada: Hydrology, Hydrochemistry, and Vegetation at the Mir
Theme I. Inventory, stratigraphy and conservation of mires and peatlands
We studied water levels, hydrochemistry, vegetation, and peat characteristics of 17 lagg transects in coastal British Columbia, Canada. Based on field observations, the laggs were classified into two hydrotopographic lagg forms:  marginal depression, and  flat transition. We split these forms into four vegetative types: [a] Spiraea thicket, [b] Carex fen, [c] peaty forest, and [d] direct transition to forest (without an ecotone). Greater understanding of regional lagg types contributes to better management, helps identify conservation sites, and allows for improvement of restoration plans for raised bogs in coastal British Columbia.
