The fur trade, timber harvesting, dams and mills and agriculture degraded freshwater habitats and decreased the carrying capability of most North American streams. Beaver populations have been trapped to near-extinction by 1800, and log drives and apparent-chopping additional exacerbated stream erosion and habitat decline. As timber and fur gave method to agriculture, freshwater Atlantic salmon habitat was further more compromised. Based on historian D.W. Dunfield (1985) "more than 50 % of your historic Atlantic salmon runs had been shed in North America by 1850".
