OPTIMIZING POLLINATOR SERVICES: DESIGNING LANDSCAPE-LEVEL FLORAL RESOURCES FOR BEE CONSERVATION

Abstract

Bees and other pollinating insects are highly valued due to their contribution to the well-being of ecosystems and food security, though there is a threat to their services due to habitat destruction and loss of complexity in the landscape.  This research investigates the impacts of scale architecture of the floral resources on the pollination services provided by 20 various species of bees.  An experimental study was conducted in a few habitat patches to quantify the vital ecological parameters, including the visit rate per flower, the quantity of pollen deposition, floral variety index (Shannon), and quality of nesting environment, and the forage range.  The findings demonstrate that the differences among species are numerous. Bee_5, Bee_9 and Bee_15 are very productive pollinators and consistently over 85 percent efficiency rates are achieved.  The relation between floral diversity and pollination efficiency was positive and strong (r > 0.7), which demonstrates the significance of having diversity of plants.  Regression models showed that the type of flowers as well as quality of the nests were considered the two most significant predictors of pollination performance.  Based on study done seasonally, most services were offered during the spring and late summer. This indicates the significance of supplying of flowers throughout the year.  Cluster analysis divided bee species into groups depending on their ecological functions (specialist, generalist, low-performing). This has assisted us to develop customized protection strategies.  Such findings were verified using visualisations like the hybrid plot, scatter plot, and boxplot.  Here, the study reveals that in order to derive optimal pollinator benefits, there is a need to adopt an integrated approach that entails enhancing nesting habitats, forage corridors and floral diversity.  The findings aid in the development of landscapes that are pollution friendly to the pollinators and in application of agroecological procedures that are environment friendly.
