Prairie farmers and ranchers can further enhance biodiversity on their land


“DUC has been working on the Canadian Prairies since our organization was established more than 80 years ago,” says Karla Guyn, chief executive officer for DUC. “We have a strong relationship with, and a deep respect for, the farmers and ranchers who steward the lands that support biodiversity in Canada. Working together, we can unite the needs of conservation and agriculture on this important working landscape.”
Over the next five years, the Weston Family Prairie Grasslands Initiative will contribute $5 million to DUC’s conservation easement program that will see more than 10,000 hectares (24,710 acres) of vital habitat protected. This contribution directly benefits agricultural producers while maintaining Canada’s biodiversity and providing habitat for a wide variety of species including waterfowl, songbirds and pollinators.  ....

Pesticide imidacloprid threatens future for key pollinator

An insecticide used to control pest infestations on squash and pumpkins significantly hinders the reproduction of ground-nesting bees valuable pollinators for many food crops, a new University of Guelph study has revealed.
This first-ever study of pesticide impacts on a ground-nesting bee in a real-world context found female hoary squash bees exposed to imidacloprid dug 85 per cent fewer nests, collected less pollen from crop flowers and produced 89 per cent fewer offspring than unexposed bees.
Because they re not making nests and not collecting pollen, they cannot raise offspring, said Dr. Susan Willis Chan, a post-doc in the School of Environmental Sciences (SES), who conducted the study with Dr. Nigel Raine, holder of the Rebanks Family Chair in Pollinator Conservation in SES. That means imidacloprid-exposed populations are going to decline. ....
