Fire-herbivory feedbacks strongly influence the formation of grazing lawns in savanna ecosystems. Preliminary findings suggest that small-scale (< 25 ha) fires can engineer grazing lawns by concentrating herbivores on the post-burn green flush; however, the persistence of such grazing lawns over the longer term and without repeated fire is unknown.
We used high-resolution Light Detection and Ranging (LiDAR) to investigate the long-term effects of fire manipulation on short grass structure (height, cover, volume, and spatial continuity) and grazing lawn establishment in Kruger National Park, South Africa. We analysed the effects of fire exclusion and experimental burns applied over a 7-year period (2013-2019) followed by a one-year cessation of burning at varying spatial scales during the early and late dry seasons.
Fires contributed a fourfold increase in short grass cover, regardless of fire season or size. The distribution of grass height differed significantly between fire-induced..., The dataset consists of short grass vegetation metrics (height, cover, volume, patch sizes) derived from drone-based LiDAR., , # Small-scale fires interact with herbivore feedbacks to create persistent grazing lawn environments
This dataset contains two tabular files that contain UAV-LiDAR derived grass metrics across the fire treatments:
1. GrassHeight.csv
2. GrassMetrics - GrassMetrics Excel file has 4 spreadsheets (GrassCover, GrassVolume, GrassPatchSize and GrassHeight-semivariance).
