- Description:
- Airborne hyperspectral data, in-situ handheld spectroradiometer measurements, and foliar samples have been collected for two study sites on the University of Idaho Experimental Forest. The study sites are 16-year old plantations of Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, and ponderosa pine, (Pinus ponderosa Dougl. Ex Laws) trees on mixed soil parent materials. The plantations include control (no fertilizer) and multi-fertilization treatments (200 lbs. N, 100 lbs. K, 10 lbs. Cu, 80 lbs. S and 5 lbs. B) as part of a tree nutrition study evaluating growth and yield response. In general, initial foliar spectra analysis shows that the unfertilized DF and PP stands have higher spectral reflectance than the fertilized stands across the visible and near infrared wavelengths. These differences can also be detected and mapped with airborne hyperspectral imagery. Hypotheses for these differences will be developed and tested. This work provides background for study of foliar nutrition and broader mapping using hyperspectral imagery. The long-term goal will be to integrate these tools to provide fertilization recommendations, monitoring of response and overall forest health over broad regions.
