After drought, vegetation declined where plots were cut four times a year
Where plots were cut four times a year, vegetation declined after drought. No decline was detected with two cuts. Species number had little effect.
The study, in plain language
A grassland can lose vegetation during drought and recover some of it later. To separate these stages, the team varied species number, cutting frequency, fertilization, and rainfall in field plots.
After drought, aboveground vegetation declined where plots were cut four times a year, but no detectable decline occurred where they were cut twice. The relationship between species number and resistance was small and changed between years. In the following spring, more species went along with better recovery only under more intensive management.
The key idea
In this grassland, cutting frequency was more closely linked to drought resistance than species number.
