Abstract [en]

A current issue is whether it is possible to evaluate the environmental qualities of individual meadows and pastures based solely on information about some of their attributes. The question is: would biologists make concordant evaluations and, if so, which attributes would be relevant. The aim of this study was to investigate the possibility of developing a model that can classify grassland by environmental values based on survey data. The reason is the policy demand to prioritise measures for preserving the environmental qualities of grassland cost-effectively. A questionnaire was used in which 40 grassland-biology experts classified 50 semi-natural grassland objects into value deciles based on survey data. The grassland objects were randomly spread across Sweden, and described by eight attributes. The study indicates that: (i) domestic experts in biodiversity conservation are quite concordant in assessing semi-natural grasslands; (ii) it is possible to quantitatively assess the general environmental quality of a grassland object by means of a simple, linear prediction model, and less than 10 carefully selected variables suffice to characterise a grassland object in a condensed but balanced way; and (iii) 'number of positive indicator species' is the variable the experts most heavily relied upon in their assessments of grassland environmental qualities.
