2014 Pahove Chapter: Schedule of Upcoming Events
Tuesday, April 8th @ 7 pm @ the MKNC-Irrigated Wet Meadows, Livestock, and Ducks – Debunking the Bias presented by Chris, Ducks Unlimited
Flood-irrigated wet meadows on private working lands in the Snake River Plain provide the critical staging resources for migrating waterbirds and replaces our lost floodplain functions. The maintenance of this agricultural practice is critical to continental waterbird populations and basic human values and services often taken for granted. Colson
