3 PREFACE This Reference Guide is intended to assist producers in developing an environmental action plan for their farm. This is a plan that enhances our use of natural resources and reduces the possibility of accidental harm to soil, air, water and biodiversity values. It is one of a number of publications prepared to support the implementation of the BC Environmental Farm Plan (EFP) Program and includes a convenient summary of current legislation and regulations as well as beneficial management practices. Also included are references to other published material that might be useful in implementing an Environmental Farm Plan. Completing an EFP will provide farmers and ranchers with an understanding of agriculturally related environmental regulations and of farm management practices that enhance environmental values. In many cases the outcome of improved water and nutrient management will also be profitable. Protecting riparian areas can improve water quality as well as enhance fish and wildlife habitat. Your decision to complete the EFP Program will bring positive recognition to yourself and your industry. The BC Agricultural Research & Development Corporation (ARDCorp), in cooperation with federal and provincial governments, encourages all farmers to take the opportunity provided by the BC EFP Program to develop a plan that addresses environmental concerns on their farms as well as raises awareness of environmental issues pertinent to the industry. Doing so demonstrates the continuing commitment of our industry to responsible stewardship of the natural resources that are essential to a sustainable and economically viable agriculture industry for many generations to come. On behalf of the Board of Directors, Dick Klein Geltink Chair BC Agricultural Research & Development Corporation November 2010 PREFACE iii
