Abstract
Conservation Translocation (CT), which includes reintroduction, reinforcement and introduction, is gaining momentum, responding to serious population decline in many orchids. Orchid conservation underpinned by a greater emphasis on understanding biotic and abiotic factors of habitats is critical for successful recovery and restoration programmes. Anacamptis morio, commonly known as green-winged orchid (GWO), is a terrestrial orchid found throughout Europe, but populations in England rapidly declined in its native range in the last several decades. The current study explored the relationship between soil abiotic characteristics and the community composition of key fungal groups. Wild sites in Essex and Cumbria in England, where successful colonies are currently present, were compared to potential sites for CT in Cumbria. The Cumbrian sites managed by cattle grazing include the wild site and three potential CT sites, with two of them hosting no GWO plants. The Essex site, fOxley Meadow, where no cattle is used for grassland management, hosts the largest population of GWO in England. The aim of this study was to understand whether the community composition of fungi and soil characteristics of the potential CT sites in Cumbria are nearly compatible with that of Oxley Meadow. Oxley Meadow, with around 65,000 plants, stands out as a unique habitat compared to all Cumbria sites, as it showed low organic content. Nitrate and phosphate content were smaller for Oxley Meadow compared to other Cumbrian sites. The proportion of Basidiomycota fungi was greater in Oxley Meadow compared to all Cumbrian sites where Ascomycota dominated. The abundant fungal group found in Oxley Meadow was Agaricales. From Agariclaes, Hygrophoraceae or waxcaps fungi are considered an indicator group of fungi and were the most abundant group in Oxley Meadow. They have a negative correlation with targeted key fungal groups and abiotic parameters. More in-depth assessments using additional primers are essential to better understand the fungal diversity and how this diversity translates to the resilience of orchid habitats. This preliminary study points to future studies to assess whether sites are near-compatible to the wild site where large colonies are present using additional primers collected over different time scales.
