Systematic grid demographic monitoring of aspen
Local Knowledge Graph (40 entities)
Loading graph...
Knowledge graph centered on Systematic grid demographic monitoring of aspen with 40 nodes and 79 connections. Top connected: quadrat sampling method, drought stress, microclimate heterogeneity, NDVI, spectral reflectance.
Description
Systematic establishment of gridded plots across watersheds followed by long-term monitoring of tagged individual trees for mortality and recruitment rates. Combined with environmental characterization of each plot.
Typical Equipment
- GPS units for plot positioning
- tree tags
- GPS units or measuring devices for spatial coordinates
- GPS units for elevation
- clinometer for slope
- compass for aspect
- soil sampling tools
- data recording sheets
- replacement tags for new recruits
Output Measurements
- mortality rates
- recruitment rates
- environmental variables
