Markus Wagner; Ansgar Kahmen; Helmut Schlumprecht; et al. Applied Vegetation Science 2007. doi:10.1658/1402-2001(2007)10[15:pohyig]2.0.co;2
Other claims from this paper (6)
- Method / resource Species-composition models gave the best herbage-yield predictions.
- Method / resource Ellenberg N-values and NMDS scores performed equally well.
- Method / resource Soil-variable predictions were least accurate.
- Method / resource N-value and NMDS models accurately predicted site productivity rank order in 2002.
- Method / resource N-value and NMDS models did not accurately predict actual site herbage yield.
- Recommendation The authors recommend calling Ellenberg N-values productivity values.
