Fig. 1. Study Site in the Valdivia-Province Coastal System, Chile. The management areas are located in black along the coast. In some cases two management areas are listed due to space constraints (i.e., Huape A and Huape B). Watersheds are numbered from 1 to 4. Some fisher syndicates have more than one management area. The influence of forest plantations (high chlorophyll-a concentration values in the nearshore and loco shellfish with high levels of shell-boring organisms) extends from the outlet of Rio Valdivia (the river from the Valdivian watershed, #3) northward (management areas Punta Numpulli northward).
