FLORAL ENHANCEMENTS CAN MITIGATE THE NEGATIVE EFFECTS OF LAND-USE CHANGE ON POLLINATOR RESOURCE AVAILABILITY, BUT THEIR VALUE WILL DEPEND ON PLANT IDENTITY, PLANT DIVERSITY, AND LANDSCAPE CONTEXT; FOR INSTANCE, ENHANCEMENTS MAY BE MOST EFFECTIVE IN INTERMEDIATELY-DISTURBED LANDSCAPES, THOUGH THIS HYPOTHESIS HAS NOT BEEN RIGOROUSLY TESTED. FURTHERMORE, WHILE FLORAL ENHANCEMENTS IN AGRICULTURAL HABITATS HAVE BEEN RELATIVELY WELL STUDIED, THEIR VALUE WITHIN DEVELOPED LANDSCAPES IS LESS WELL UNDERSTOOD. WE WILL EVALUATE ECOLOGICAL AND SOCIO-ECONOMIC FACTORS THAT MEDIATE THE VALUE OF FLORAL ENHANCEMENTS FOR BEES WITHIN THE DEVELOPED LANDSCAPE THROUGH THREE OBJECTIVES. FIRSTLY, WE WILL EXAMINE HOW REGION OF ORIGIN AND ABIOTIC CONDITIONS AFFECT PLANT ATTRACTIVENESS AND VALUE TO BEES BY COMPARING CONGENERIC PAIRS OF NATIVE AND NON-NATIVE GARDEN PLANTS GROWN UNDER DIFFERENT IRRIGATION TREATMENTS. SECONDLY, WE WILL DETERMINE HOW PLANT DIVERSITY AND LANDSCAPE CONTEXT INTERACT TO MEDIATE THE VALUE OF POLLINATOR GARDENS FOR BEES BY SELECTING EXISTING RESOURCE-POOR GARDENS ALONG A LANDSCAPE GRADIENT FROM LOW TO HIGH DEVELOPMENT, ENHANCING THEM WITH EITHER A HIGH OR LOW DIVERSITY OF BEE PLANTS, AND MONITORING THEM BEFORE AND AFTER ENHANCEMENT. THIRDLY, WE WILL IDENTIFY SOCIO-ECONOMIC BARRIERS TO CHANGING GARDENING PRACTICES USING FOCUS GROUPS AND A RANDOM SURVEY. THIS PROJECT ADDRESSES PROGRAM PRIORITIES TO 1) BETTER UNDERSTAND FACTORS INFLUENCING POLLINATOR HEALTH INCLUDING ABIOTIC, BIOTIC, AND SOCIAL FACTORS, AND 2) DEVELOP AND EVALUATE MANAGEMENT PRACTICES THAT WILL BE ADOPTED BY STAKEHOLDERS FOR HEALTHY POLLINATORS. OUR PROJECT WILL PROVIDE NOVEL RESEARCH-BASED RECOMMENDATIONS AND DIRECT MEASUREMENTS OF CONSERVATION OUTCOMES FOR POLLINATOR GARDENS ACROSS A LANDSCAPE GRADIENT.
