Authors’ contribution
This paper builds on the protocol as designed originally by the Mountain Invasion Research Network (MIREN) by SH, KM, AP, JMA, LJR, JRA, CD, HD, PE, GJ, CK and BN. The idea for the paper and further fine-tuning of the protocol stems from a MIREN workshop in 2019, attended by SH, KM, AP, JMA, AB, IR, LJR, AnB, ARB, CC, BE, AG, AH, TTH, PK, CK, DP, EFL, JL, RVC, SR, VV, TW, REMW, SZ, and TS. SH, JJL and TS led the writing of the manuscript, with contributions by the MIREN steering committee (KM, AP, JMA, AB, LAC, IR, LJR). All authors contributed critically to the drafts – based on their experience in applying the protocol in their regions – and gave final approval for publication.
