Chapter 5: Vegetation
In southern and west central
Individual animals are too small to appear on all except very large-scale images. However, some animals (e.g. beaver) profoundly affect drainage systems.
5.23: Fen and Black Spruce Islands South of East Braintree
Teardrop-shaped islands 1 are surrounded by almost horizontal fen 2 covered by low-lying vegetation. The islands are covered by black spruce (Picea mariana), dark-toned, 3 and tamarack (Larix laricina), light-toned 4. The surface form of the islands is determined by surface and groundwater flow.[i] The terrain is very difficult to cross; hence the absence of any obvious human impact.
