c . Very little information is available concerning the soil<br />
forming processes in the Canadian subarctic and arctic regions .<br />
This<br />
is especially true of cryoturbation which is probably one of the most<br />
important factors .<br />
Cryoturbation affects not only the development<br />
of the soil but also distribution of vegetation and<br />
the stability of<br />
terrain . It is recommended that soil scientists study this process<br />
jointly with ecologists to determine the effect of cryoturbation on the<br />
ecosystem .<br />
d . In ecological studies, such as the study of plant succession<br />
and re-establishment of vegetative cover on disturbed areas, soil<br />
scientists should be involved together with ecologists and botanists .<br />
Soil scientists would provide information relevant to plant growth .<br />
This would include the physical<br />
(texture, structure) and chemical<br />
(nutrient content, pH)<br />
properties of the soils as well as its moisture<br />
content, depth of active layer,<br />
soil temperature, ice content and the<br />
degree of cryoturbation .<br />
e . Panchromatic, small-scale black and white photographs which<br />
were taken in the mid-1950's were used to conduct soil studies .<br />
If<br />
reconnaissance surveys and other environmental studies are to be<br />
undertaken in the future some funds and preplanning must be directed<br />
towards obtaining higher quality,<br />
recent, multispectral aerial<br />
photography and other remote sensing data . Studies carried out in<br />
other areas using recent remote sensing data were more accurate and<br />
provided greater amounts of<br />
terrain information than was obtained using<br />
old panchromatic, small-scale, black and white photographs .
