Invasions are one of main drivers transforming the functions of forest ecosystems. The invasion of alien fungus Hymenoscyphus fraxineus is still reducing the abundance of Fraxinus excelsior throughout temperate Europe. F.

Formerly, before the current Hymenoscyphus fraxineus epidemic, symptomatic ash twigs were habitually colonized by fungi occurring occasionally in the early stages of ash diseases. Some of these fungi are endophytes or facultative parasites.

Notes on invasive and expansive trees and shrubs
Expansion and invasion of plants indicate successful colonization and competitive abilities of species. There are fewer invasive and expansive woody plants than herbs.

Gelatinous Fibres in Ash (Fraxinus excelsior L.) [PDF]
TENSION wood in dicotyledonous trees and shrubs is recognized by the presence of gelatinous fibres. These fibres have an inner layer, composed almost entirely of cellulose (the G-layer), which may replace either the S3 or both the S3 and S2 layers of the secondary wall of the fibres.

Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

The potential of seedbank digital information in plant conservation
Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number of maternal plants and seed traits, we can attempt the estimation of genetic ...

Conservation status of species used in the UK herbal medicine industry
Given the ongoing biodiversity crisis, sustainable use and management of medicinal plants is critical. We assessed the conservation status, threats and conservation actions of 298 species sold by UK suppliers to medical herbalists. We found that most species used are unevaluated, representing a gap in conservation knowledge, and of those with ...

Preliminary genetic barcodes for ash (Fraxinus) species and generation of new wide hybrids
Societal Impact Statement The world‐wide diversity of ash trees includes genetic information encoding resistance to the ash dieback fungus and the emerald ash borer beetle, which are currently devastating ash populations in Europe and North America.
