Spectral Reflectance Changes Accompanying a Post Fire Recovery Sequence in a Subarctic Spruce Lichen Woodland
A sequence of burned surfaces aged 0, 1, 2, 24, and 80 years was investigated regarding changes in the spectral distribution of reflected light. Controls were introduced to isolate diurnal and seasonal effects. The results show gradually increasing reflectance with increasing age of burn. With the e...
