Grassland managers not responding to phenology shifts

Time series of the national average 1st hay cut for 1951– 2011 (black circles), 1991–2011 (grey triangles) and beginning of flowering of meadow foxtail (black squares). 

In Germany, grasses in hayfields have been maturing faster due to warming.

Yet, hay cutting hasn't kept pace.

Amazingly, over 50 years of data.

Has forage quality suffered?
