VALUES OF THE BIODIVERSITY
Environmental value
The environmental value of biodiversity is found by examining each ecosystem process and identifying the ecosystem services that cause it. For example, in wetlands the vegetation captures water-carried sediment and the soil organisms break down a range of nutrients and pollutants washed into the area. These processes provide the ecosystem the help of purifying water. Wetlands also act as spawning and nursery grounds for some fish and provide a refuge for animals in times of drought.
Some ecosystem services are very easy to overlook until the underlying process is impaired. For instance, dry land salinity has emerged as a problem following sustained clearance of deep rooted perennial plants over wide areas. Water tables have risen which carry dissolved salts which then concentrate in the soil. We can say that where vegetation contains a significant proportion of deep rooted plants like trees, it provides the ecosystem the service of moderating water table levels and thus contributes to soil fertility. Similarly, the value of oxygen production is ignored when we have adequate supplies.
Social value
The social value of biodiversity includes aesthetic, recreational, cultural and spiritual values. To this we can add health benefits resulting from recreational and other activities. There can be many differences in landscape and biodiversity according to age, socioeconomic factors and cultural influences. In Australia, people up to
