Ecology of Some Mined Areas in North Dakota.
North Dakota Geol Survey Educational Ser 5 Grand Forks North Dakota, 1973 :25-47
The species composition and diversity and soil physical and chemical properties of some unmined areas have been compared with spoil banks that have been revegetated naturally over a period of time. The entire study has been located in such a way that the spoil materials represent a series along a time gradient. Emphasis has been laid on abundance of species in relation to water retention properties and macro- and micro-nutrient content of the soils. This study provides an insight into the regional ecological processes in operation that will have a bearing on the present as well as future revegetation and reclamation efforts.
