Document Summary
Hudson bay lowlands continued - natural history (lecture 6) Dominant features in the hudson bay lowlands include; string bogs they are perpendicular to the slope of the land, peat, muck, and marrow. Raised beach ridges are parallel to the land. The bedrock that underlies the hudson bay lowlands is sedimentary rock. Rivers make deposits on the shoreline making higher and drier habitats ideal for plant growth (orchids sparrow"s egg lady slipper [calciphilic plant]). There is then a shrub layer, and then behind that are the trees. Ninebark is also found in the shrub layer. The shrub layer is dominated with willows, wolf-willows (not a true willow). The orange crowned warbler, fox sparrow, and the pine grosbeak use the shrub layer to nest. Poplars grow in the forested area (coniferous trees are dominant however). One species of coniferous trees are dominant, the black spruce. The black spruce form shade, shade tolerant plants will grow beneath them.
