The purpose of this project was to monitor the short-term impact (year 10) of forest soil compaction and organic matter removal on density and relative abundance of soil fauna and diversity of oribatid mite species. This work also established the basis for monitoring long-term recovery of the soil fauna community throughout a full timber rotation. Timber harvesting and site preparation modify a variety of physical and chemical properties in the soil, consequently affecting soil pore space, composition and amount of organic matter, forest floor and mineral soil temperatures and soil moisture. Alteration of these properties can adversely affect soil fauna density and diversity as well as alter their living space and food supply. Two features of the soil ecosystem, organic matter and soil porosity, can be related to all alterable soil properties that influence soil productivity and these are the features that were experimentally modified in the Long Term Soil Productivity (LTSP) project.
