NINA – Norsk institutt for naturforskning

Year: 2019
Project manager: Bård-Jørgen Bårdsen
Project code: 642018

This is a continuation of the project that was financed this year. The overall aim of the project is to use Structural Equation Models (SEMs), or path analysis, to assess the relative influence of ecological and social factors in shaping population dynamics of Norwegian semi-domestic reindeer at several levels of social and administrative organization. The project is progressing as we have: 1) recently been granted access to the official statistics on the reindeer husbandry at the siida share (licensed owner) level from the Norwegian Agriculture Agency (NAA), but for fewer years period than we asked for; 2) extracted and ran pre-analyses of satellite-derived data on vegetation biomass and meteorological data across all reindeer districts in Norway. We are still awaiting an answer on our requested access to the official district-level-data from NAA, to receive the requested data (NAA), and data on predator presence/numbers (in dialogue with the Norwegian Environment Agency; NEA). As soon as we have the data at hand, we are ready to run the SEMs. In the original proposal, this was scheduled to take place in the end of 2017 and early 2018, but as NAA have spent <1.5 year granting us access (and we have spent a lot of resources following up our request), we are forced re-schedule and make all the SEMs in 2019. Previous studies have focused on the district-level, but we propose to expand this by applying SEMs at the level of the siida share and siida in addition to the district-level.
