Conservation of soil moisture by different stone covers on alpine talus slopes (Lassen, California)

Auteur :
PÉREZ, F.L.

Description :
This study reports on the influence of stone covers with different clast sizes on the soil moisture of alpine talus slopes in Lassen. Fifteen four-plot sets were sampled in the dry season (July 1990) in sandy areas and in talus covered with pebbles, cobbles, or blocks between 2740 and 2775 m. The objectives of this study are to : evaluate the role of stone size in water conservation by comparing soil moisture under layers of stones with different sizes; replicate with an irrigation field experiment the moisture conditions found in bare talus and under stone covers; and monitor evaporation losses from these experimental plots for an extended time period.
