Spectral reflectance changes accompanying a post fire recovery sequence in a subarctic spruce lichen woodland

Remote Sensing of Environment 8(1): 11-24

Spectral reflectance changes accompanying a post fire recovery sequence in a subarctic spruce lichen woodland

A sequence of burned surfaces aged 0, 1, 2, 25 and 80 yr was investigated regarding changes in the spectral distribution of reflected light. Controls were introduced to isolate diurnal and seasonal effects. Gradually increasing reflectance with increasing age of burn was noted. With the establishment of vegetation a new set of absorption and reflectance criteria were established, substantially altering the spectral characteristics. The apparent effect of a mature forest canopy was ambiguous. Diffuse and overcast conditions reduced the reflectance for all surfaces. Further work was suggested to reinforce results for surfaces with low sampling replication.
