Measuring Soil Biodiversity in invertebrates

These chemical and physical properties influence what type of organisms can survive in that type of soil. The amount of moisture or the amount of carbon would affect such property. ...

Habitat conservation
Habitat conservation is a land management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.
