Addressing the problem of sulphur cinquefoil in Canada

Sulphur cinquefoil (Potentilla recta), is a long-lived perennial native to Eurasia. It was introduced to North America over a hundred years ago. Since then, it has invaded disturbed habitats, such as roadsides and pastureland and also semi-natural habitats such as open forests. It is able to hybridize with North American cinquefoil species or to di... >>

ALARM (Assessing Large Scale Environmental Risks for Biodiversity with Tested Methods)

Climate change, environmental chemicals, biological invasions and pollinator loss are substantial environmental changes resulting from human activities. In the past, these four pressures have generally been studied independently of one another. Yet it is clear that, on a large scale, they do interact, potentially producing effects on ecosystem dive... >>

Arming DPR Korea's farmers with tools to tackle soil pests

Food crops such as rice, maize and cabbage, are grown over two-thirds (1.2 Million hectares) of DPR Korea’s total arable land. Their production is essential for supplying the population with adequate food and nutrition. Over recent years however, these food crops have come under increasing threat from soil-borne insects. Damage inflicted by t... >>

BACCARA- Biodiversity and Climate Change, a Risk Analysis

Climate change, in particular increased temperatures, levels of atmospheric carbon dioxide, changes in precipitation and in the frequency and severity of extreme climatic events, is known to have serious impact on forest ecosystems and forest productivity. Global warming leads to longer growing seasons and increased water losses, affecting forest p... >>

Biological control of brown marmorated stink bug

The brown marmorated stink bug, Halyomorpha halys (Stal) (Hemiptera: Pentatomidae), is native to China, Japan, Taiwan and Korea and is invasive in the US, Canada and Switzerland. Due to its extremely wide host range it is a serious pest of many fruit trees, shrubs, ornamentals, fruit and vegetable crops. In North America it was first detected in ... >>

Biological control of garlic mustard

Garlic mustard, Alliaria petiolata, is a biennial cruciferous plant of European origin. It is one of the few non-indigenous herbaceous species able to invade and dominate the understory of North American forests, and is considered one of the most serious invaders in the north-eastern and midwestern USA and south-eastern Canada. This project to ... >>

Biological control of hawkweeds

European hawkweeds (Pilosella spp.) have been introduced into New Zealand and North America where several species have become troublesome weeds. A number of Pilosella species are invasive in the North-western USA and in British Columbia in Canada: Pilosella officinarum (Hieracium pilosella, mouse-ear hawkweed), P. aurantiaca (H. aurantiacum, orange... >>

Biological control of houndstongue

Houndstongue (Cynoglossum officinale), is a facultative biennial, native to Europe and parts of Asia. Introduced into North America in the mid-19th century, it now occurs in nearly all Canadian provinces and adjacent US states. This rangeland weed hinders the establishment of forage species in new pastures. The barbed nutlets become attached to cat... >>

Biological control of Oxeye daisy

Oxeye daisy (Leucanthemum vulgare) is a perennial herb with showy flower heads. Originating from Europe, oxeye daisy has been introduced to many other parts of the world both unintentionally as contaminant of crop seeds, and intentionally as an ornamental plant. Oxeye daisy has become naturalized throughout most of temperate North America, where it... >>

Biological control of toadflaxes

The western USA and Canada have been invaded by what appears to be three different morphological types of toadflax. These are yellow toadflax (Linaria vulgaris), Dalmatian toadflax (L. dalmatica, also referred to as L. genistifolia dalmatica, L. dalmatica dalmatica or L. dalmatica macedonica) and a type that appears to be morphologically between ye... >>
