The worldwide decline in bee populations is threatening the delivery of pollination services, thus leading to the development of pollinator restoration strategies. In the United States, one way to protect and restore bee populations is to use seed mixes composed of pollinator-friendly native plants to revegetate federal lands following disturbance.

Scientists assessed the attractiveness and use by bees of 24 native plant species that are standard for revegetation projects (focal plants) on national forest lands in western Montana.

Australian Invasive Species Council.

The 2021 independent State of Environment Report has highlighted that invasive species are identified as the most prevalent threat to Australian wildlife and are the primary cause of extinction events. The report warns of the compounding and devastating impact of multiple threats to Australia’s environment.

Commonwealth Scientific and Industrial Research Organisation (Australia).

A new report, Fighting Plagues and Predators: Australia’s Path to a Pest and Weed-Free Future [PDF,  12 MB], reveals the environment is facing a "sliding doors" moment, with two possible futures for Australia, depending on the decisions made today. It highlights a looming wave of new extinctions and outlines two futures for Australia, one based on an unsustainable ‘business as usual’ approach and the other based on implementing targeted actions that will help save our unique biodiversity. The report pegs the conservative cost of damage caused by invasive species in Australia – predominantly weeds, feral cats, rabbits and fire ants – at $390 billion over the past six decades and around $25 billion each year and growing.

National Environmental Science Programme (Australia). Threatened Species Recovery Hub.

New research by the Threatened Species Recovery Hub has shown that invasive or pest species are a problem for 1,257 threatened species in Australia, or about four out of five species. The research which has been published in the scientific journal Pacific Conservation Biology also identified the top ten invasive species based on how many threatened species they impact. Lead researcher Stephen Kearney from the University of Queensland said many people may be surprised at which species top the list. “Rabbits, a plant root disease and feral pigs are the top three pest species impacting Australia’s threatened species,” Mr Kearney said.
