DATA & FILE OVERVIEW

File List: 
- Swiss_Agroforestry_Tree_Monitoring_data.csv



METHODOLOGICAL INFORMATION

Starting in 2014, the trees were measured every three years. The monitoring was limited to the above ground biomass. Diameter at breast height (DBH) was measured using a slide gauge and the location of the measurement was marked with a paint spray. Tree height was measured using triangulation with a “Vertex 5” tool. Exactly the same trees were measured in each sampling round.

For the actual monitoring, we selected trees inside the agroforestry systems, avoiding the outer tree rows and the first and last trees of the rows to be monitored. The number of trees investigated was roughly in proportion to the number of trees of the respective agroforestry system.
