The BC Ministry of Forest's EP 1148 Long-term Soil Productivity (LTSP) study addresses two key factors— soil porosity and site organic matter—that potentially limit tree growth and site productivity in the timber-harvesting land base and that can be affected by forestry operations.

This establishment report for EP 1148, "The effects of soil compaction and organic matter retention on long-term soil productivity in British Columbia (Experimental Project 1148)", is accompanied by a floppy disk containing 12 data sets (see 2023.2.2.11.2).

This image is part of the outbound sequence of aerial images obtained on the helicopter flight to the Klutlan Glacier study site. The sequence starts from the base camp at the White River crossing on the Alaska Highway and heads south, to a point just upvalley of the debris-covered terminus (approx. 10-15 km from Alaska border), and turning back north to the landing spot on the Generc River floodplain close to the study site (see Fig. 1 in paper).
