The future is looking a little brighter for seabirds in French Polynesia following the first successful removal of invasive rats in the Marquesas Archipelago. The project, implemented by the Societe d’Ornithologie de Polynesie (Manu), Island Conservation, BirdLife International and Association Vaiku’a i te manu o Ua, will protect a nationally significant population of 90,000 Sooty Terns. Invasive rats present on the island devoured seabird eggs and chicks and native plants. Free from invasive rats, seabirds can once again safely nest and native plants can grow tall and thrive.

Both scientists and regulators have had a lot to say about the growing problem of herbicide resistance and how weed management techniques need to change in response. But there have been few organized opportunities for farmers to make their voices heard and to share their experiences in managing herbicide-resistant weeds.
Great Lakes Fishery Commission.
The Great Lakes Fishery Commission today reported that populations of the invasive, parasitic sea lamprey remain at near-historic lows, below targets, in Lakes Michigan and Ontario, and above target, but holding steady, in Lakes Huron, Superior and Erie. Sea lamprey populations in Lake Huron are close to target levels and have been holding steady for the past five years. Abundances in Lakes Superior and Erie remain above target but have also decreased significantly since the near-record highs observed in 2017. Sea lampreys are the worst of the alien species to invade the Great Lakes. Before control, sea lampreys destroyed many times the human fish catch. Today, sea lamprey control is the foundation of the $7 billion Great Lakes fishery. The Commission and its partners are encouraged by the overall decrease in abundance of sea lampreys throughout the Great Lakes basin during 2019, but caution that environmental conditions, such as a prolonged spring and high precipitation events, contributed to the decrease.
Western Governors Association.
The Invasive Species Data Mobilization Campaign of the Western Governors’ Association seeks to encourage national, state, and local land managers, private landowners, and non-governmental organizations to enter previously unavailable data into new or existing invasive species data management platforms using recommendations developed by WGA and invasive species data experts.
High-quality information is an essential weapon in the fight against invasive species in the West. Land managers, conservation groups, industry, and private landowners need accurate, current regional invasive species occurrence data. Technological barriers and standardization issues, however, often prevent wide sharing of useful invasive species occurrence data.

To tackle devastating crop diseases, Africa should boost regional plant surveillance, writes Mustafa O. Jibrin. Recently, a tomato insect pest, Tuta absoluta, swept across Nigeria, devastating tomato fields and leading to immeasurable financial losses and emotional trauma. T. absoluta originated from the Andean region in South America. The invasive nature of T. absoluta and its resistance to conventional insecticides make it difficult to control. If not handled properly, the effect of this pest could hold the continent's agriculture hostage.

What losses would corn and soybean growers experience if they were forced to eliminate herbicides and other control techniques from their weed management toolbox? A team of experts with the Weed Science Society of America (WSSA) found that in the U.S. and Canada, about half of both crops would be lost to uncontrolled weeds, costing growers about $43 billion annually.
