The Catalan butterfly monitoring scheme has the capacity to detect effects of modifying agricultural practices

Abstract

Impacts of agricultural management practices on the receiving environment are seldom suit-ably assessed because environmental monitoring is costly. In this regard, data generated by already exist-ing environmental survey networks (ESNs) may have suf¿cient capacity to detect effects. Here, we studythe capacity of the Catalan butterfly monitoring scheme (CBMS) to detect differences in butter abun-dance due to changes in agricultural practices.
