Acreage was vast (1.4 million acres) and yields were generally poor (135 lbs/acre). With pollination taken over using abundant managed M. rotundata and Nomia melanderi, production shifted to xeric regions of the Pacific Northwest (esp. Oregon, Washington and Idaho) and California. Overall production acreage shrank 6x to 250,000 acres because yields were improved to as much as 1,800 lbs per acre (my note...more realistically, the average grower in average year is getting more like 1100 pounds of clean seed per acre, but still, that is a 8x increase).},

Across this landscape in 2001, an estimated 9.1 million nesting females collectively brought 87,500 kg (96 tons) of soil to the surface in their tumuli, much of which is subsequently eroded away by wind or rain. At this rate. the oldest populated nest site would have cumulatively lost four cm to surface Subsidence as a result of the past halt century{\textquoteright}s nesting activity. Bees are probably minor agents of biogeomorphology and bioturbation except where nesting females are concentrated in long-lived Populous aggregations},
