Predictive model for annual and perennial canopy gaps > 200 cm

Description

This model can estimate percent cover of annual and perennial canopy gaps > 200 cm using percent cover of perennial canopy gaps > 200 cm and any-hit annual herbaceous cover. It was built using data from all NRI and LMF plots in the Upper Colorado River Basin where both perennial gaps and annual + perennial gaps were measure at the same time. Cases where annual and perennial gap cover was greater than 1 standard deviation above perennial gap cover were excluded because annual and perennial gap cover typically should not exceed perennial gap cover, but occasionally does does due to measurement errors. Adjusted R-squared: 0.8144; P-value < 0.001

Usage
