27 river sites in northern Tasmania were sampled during the summers of 2008/09 and 2009/10 to identify correlations between river condition and grazing land-use. The dataset includes biological data on macroinvertebrates and algae, as well as physical water quality measurements. Sites were selected across a gradient from 0% to 80% of upstream catchment area under grazing.
Use Cases
- Modeling the relationship between grazing intensity and water quality based on nutrient and sediment measurements.
- Analyzing macroinvertebrate community composition in response to land-use gradients.
- Assessing correlations between physical habitat variables like shading and fine sediments with biological indicators.
Strengths
- Data from 27 sites provides a gradient of grazing intensity from 0% to 80%.
- Multiple biological and physical variables were collected, including macroinvertebrate counts and 13 water quality parameters.
- Sites were screened to minimize confounding variables, promoting independence.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Data is from a specific region and time period (summers of 2008-2010), which may limit generalizability.
- Row count is unknown, which may limit suitability assessment.
