Measuring ecological connectivity using tagged bees and readers to integrate movement and landscape ecology for conservation management. The same tagged bee(s) connects three of four populations of a plant species, resulting in pollen (gene) flow among A, B and C. A confirmed lack of visitation to D (due to, for example, a wide highway) means the population will degrade over time for lack of gene flow and be of little conservation value unless restorative actions are taken. The effectiveness of those actions could then be monitored using the same tag detection system
