The Central Parkland Subregion
The Central Parkland Subregion extends in a broad arc up to 200
kilometres wide, north of the Grassland Natural Region and south of the
Boreal Forest Natural Region.
Within this subregion, there is a gradual transition from grassland with
groves of aspen in the south to closed aspen forest in the north.
Native vegetation is scarce because most land has been cultivated to
grow agricultural crops. The majority of the remaining natural
land is on rougher terrain or poorer soils.
Surficial deposits range from intermediate-textured hummocky and ground
moraines to fine-textured glaciolacustrine deposits and coarse outwash, kame moraine, and dune field materials. Moraines are most widespread, with kame moraines locally extensive in eastern portions. The Neutral Hills are an excellent example of ice-thrust
Aspen and balsam poplar forests are two
major forest types that occur in the Central Parkland. Both are
characterized by a lush, species rich understory. Shrub
communities of snowberry, rose, choke cherry and Saskatoon are more
extensive in the northern portion of the Central Parkland Subregion.
Elevations range from just over 500 metres where the Battle River enters Saskatchewan to around 1100 metres in western portions. Numerous permanent streams, all part of the Saskatchewan River system, cut across the subregion. Numerous lakes are scattered throughout the subregion as well as a wide variety of permanent
wetlands. Many of the lakes and wetlands are slightly to strongly saline.
