Livestock use of PBG pastures
Preliminary write-up from first week of livestock grazing of 2018 season
Devan Allen McGranahan
- GPS dataloggers were attached to three animals/pasture for the first week of grazing
- Spatial analysis identified areas of highest use (hotspots) based on frequency of logged positions within 25 m^2 cells
- Within burned patches, these hotspots will be targeted for soil nutrient sampling to maximize representation of fire-grazing interaction.
Activity hotspots from 12 GPS dataloggers fitted to three animals/pasture for first week of grazing. Grids represent calculated Voronoi polygons and only those with greater than ~400 positions/cell are filled in. Black boxes delineate 2017 burns. Bright green triangles denote soil sampling locations (approximately 2/ecological site, not shown). In each location, sheep graze the left pasture and cattle graze the right.
