Bee (Apoidea) community response to perennial grass treatments managed for livestock production and conservation

• Bee richness and abundance was higher in native grass pastures without cattle. Perennial grasses may provide some forage resources for bees. Honey bees were collected more commonly non-native pastures. Land sharing/sparing with perennial cattle can be ecologically positive. Most grasslands world-wide have been converted into various row crops agriculture pasture livestock foraging. This conversion has likely disrupted arthropod communities, including pollinating bee communities. Pollinating decline recent decades much of this attributed to intensive agricultural practices. Native warm-season promoted as alternatives [e.g., bermudagrass ( Cynodon dactylon )] beef production systems. Reestablishing an opportunity land-sharing where enable conservation practices that potentially enhance biodiversity. Therefore, such growing minimize community disruption should considered. We used colored pan traps collect four treatments plantings associated operational during 2011−2012. The were: (1) mix Bermuda tall fescue Schedonorus arundinaceus ) grazed cattle; (2) monocultures Indiangrass Sorghastrum nutans (3) polyculture [(Indiangrass, little bluestem Schizachyrium scoparium ), big Andropogon gerardii (4) generally documented greater abundances compared exotic treatments; however, treatment-level differences genera- or species-dependent.
