Effect of forest management on alpha diversity of ground vegetation in boreal forests: a model approach
The effect of various forest management types on the alpha diversity of ground vegetation was studied with an ecological simulation model. With this model, stand characteristics were simulated during different management programmes and were then used to calculate the diversity of the ground vegetati...
