How many times European grasslands were mown each year (Copernicus)

CLMS VLCC Grassland Mowing Events (GRAME) Europe 10m yearly V1
biosphere ESA ESA Copernicus active
In plain English

What it measures. Counts the number of mowing events on temporary and permanent grassland over a year, grouped as one, two, three, or four-or-more cuts.

How it's made. Produced yearly from 2017 onward by the EU's Copernicus Land Monitoring Service at 10-metre resolution, with a smallest mapped patch of a quarter hectare, across Europe's 38 countries, including French overseas territories.

How & where you'd use it. Reveals how intensively grasslands are managed, supporting work on agriculture, biodiversity, and rural policy. A companion reliability layer is available.

Official description

The High Resolution Layer Grassland Mowing Events (GRAME) raster product provides a basic land cover classification containing respectively the number of grassland mowing events within the detected Herbaceous cover layer (temporal and permanent grassland)) with a Minimum Mapping Unit (MMU) of 0.25 ha. The GRAME product will flag and map the number of mowing events (1, 2, 3, or 4+) on temporary or permanent grassland detected per year. This dataset is provided annually starting in 2017 with 10 meter rasters (fully conformant with the EEA reference grid) in 100 x 100 km tiles covering the EEA38 countries. High Resolution Layer Grasslands product is part of the European Union’s Copernicus Land Monitoring Service. Confidence layer available for the dataset. This dataset includes data from the French Overseas Territories (DOMs).
