TY - JOUR T1 - Hedgerow distribution and removal in nonforested regions of the Midwest JF - Journal of Soil and Water Conservation SP - 60 LP - 64 VL - 42 IS - 1 AU - Bradley H.

Comparison of historical and recent aerial photographs revealed a considerable range of removal rates, ranging from 0.6% removal/year to 3.1%/year. Although numerous hedgerows were removed between the settlement period and 1940, rates of removal appear to have intensified recently. Significant factors affecting removal were development of centerpivot irrigation systems, urban expansion, and construction or improvement of roads. ER -
