  A major function of soil nematodes is that they are biocontrol agents, meaning they can be used to eliminate disease causing nematodes and other organisms. This trait causes predatory nematodes to be a great resource in the battle against soil borne diseases. For more information on nematodes and how they impact soil health obtain a copy of the.

A comprehensive literature review of the factors affecting the survival of planted Douglas-fir seedlings is presented. Original data from operational planting trials was analyzed to determine the effect of some seedling, planting and environmental factors on survival.

The use of 2+1 stock was found to result in increased survival of fall-planted seedlings, but not of spring planted seedlings. rhizomes are also integral parts of the forest soil biota. The specific identities, numbers, or biomass of the organisms are poorly known for any forest soil, again probably because of the difficulty of the undertaking.

Recent research in the Douglas-fir Region (DFR) has concentrated on biolog-ical processes in soil rather than on relationships.

In British Columbia, Douglas-fir (both varieties) grows from sea level to 2, feet ( m); in Washington and Oregon it grows generally between sea level and 5, feet (1, m) (locally higher).

Mesic ponderosa pine vegetation types with Rocky Mountain Douglas-fir invading generally are between 4, and 5, feet (1, to 1, m). The effects of clearcut harvesting and fertilization of clearcuts on the structure of nematode communities were assessed at three sites in the southern interior of British Columbia.

The Shannon-Weaver and Simpson indices of diversity were greater in clearcuts than in forests. The diversity of the bacterivorous and fungivorous trophic groups were not significantly different between clearcuts. Formica spp. mound construction is fundamental to northern forests as their activities govern and shape forest floor dynamics and litter decomposition.

The interior Douglas-fir forest at Swakum Mountain contains a super colony of Formica integroides whose presence and monolithic structures dramatically demonstrate their impact on the landscape.

Senescence may appear in some old-gowth forests, although it appears that old-growth stands of Douglas-fir typically remain intact for to years. On the other hand, some stands may break up at years, while others.Nematodes move in water films in large (>1/ inch or 50 µm) pore spaces.
