Selection criteria | The main criteria that led to the exclusion of a synthesis paper were when the paper: 1) did not deal with terrestrial grasslands or the effects on grasslands could not be disentangled from other land uses; 2) did not deal with grazing management; 3) was either a non-systematic review, a non-quantitative systematic review, or a meta-regression without mean effect sizes; 4) was not written in English. Due to the high number of potentially valid synthesis papers, we applied additional exclusion criteria: [5]) the paper did not include studies conducted in Europe; 6) the paper only reported impacts on grassland or animal production, but any environmental impacts. Synthesis papers that passed the relevance criteria were subject to critical appraisal carried out on a paper-by-paper basis. The search returned 1022 synthesis papers potentially relevant for the practice object of our fiche. From the 1022 potentially relevant synthesis papers, 661 were excluded after reading the title and abstract, and 330 after reading the full text according to the above-mentioned criteria. Finally, 31 synthesis papers were selected for grazing. |
