Modelled remains of the Alpine glacierisation (climatic accumulation area) according to an increase in summer air temperature of +1 to +5 °C. The total of 100% refers to the ice cover of the reference period (1971–90). The 100%-marks of the other lines refer to the fraction of glacierisation of the corresponding Alpine country. Reading example: A rise in summer air temperature of 3 °C would reduce the Alpine ice cover (red curve) to about 20% of the glacier cover of the reference period (1971–90). The corresponding glacier remains of Switzerland (blue, dashed line) amounts to about 30%, whereas in Austria (black, dashed line) only about 7% of the glacier cover of the reference period is left.
Let the grass grow higher and thus encourage root growth. It will also allow the grass to self-seed. If you mow a path in the middle, it will show that it is indeed meant to be that way as opposed to being neglected.
