As part of a project to restore seed-rich grasslands to arable land, powerful temperature and humidity data loggers record soil temperature and relative humidity to help understand planting and growing conditions. The recorder provides samples of temperature and humidity data that can help optimize seed germination.
Because of its rich flora and fauna, the restoration of seed-rich grasslands is valuable as part of a strategy to preserve the UK's unique biodiversity. The NERC ecological hydrology center (CEH) has launched a project to test new methods for restoring these types of grasslands that have disappeared as a result of agricultural intensification. An important part of the process is to know the basics about abiotic conditions, such as temperature and humidity. The temperature and humidity data loggers has been in use at the Pegsdon Hills nature reserve in Chilterns since the summer of 2008.
In the UK, intensive farming and improved grassland management have resulted in the loss and fragmentation of high-quality, seed-rich grasslands. Some of the high-yield grasses more suited to the high-fertility conditions of intensive farming include wildflowers such as stone roses, milkweed and wildflowers, as well as herbaceous flowering plants (known as forbeses). (replaced) time.
The NERC ecological hydrology center is looking for better ways to build this species-rich prairie on top of existing agriculturally modified restoration sites. Today, many of the Forbes species are rare and confined to a few regions unaffected by agricultural development. Therefore, seed regeneration at such sites is often difficult. The usual location is the chalk plains. The second focus of the project is to establish a management system to prevent the introduction of competitive wildflower species with high yield shrub grasses from seeds or through growing transplanting plants. B: yes.
Temperature and humidity data loggers are used three times a year in spring, summer and fall, once a week. The temperature and humidity data recorder monitors factors known to affect plant colonization. Temperature and humidity data were recorded at the surface level, and temperature was also recorded 10 cm above the soil profile. These factors are important for at least two reasons. First, seeds have mechanisms for planting into many species that allow germination to take longer in the face of fluctuations in light and water levels. Too low a fluctuation indicates that too much thick vegetation blocks light and too much moisture, preventing new seeds from being planted.
Thus, the seeds of these species germinate only with sufficient variability, indicating favorable conditions for colonization. Second, the seedling stage of a plant is a stage where it is highly susceptible to abiotic factors, such as water, and successful reintroduction of the rare Forb species requires a full understanding of these factors. It is also important
"The temperature and humidity data loggers have proven to be reliable, robust and user-friendly," commented the grassland ecologist and project coordinator. He gave us samples of known temperature and humidity data about the seeds. Germination under these conditions helps to explain our results: optimized resettlement methods allow the colonization of seeds that are difficult to obtain due to the lack of a suitable "donor". Increase your chances. A place where seeds can be harvested. "
The data can be downloaded live. In this case, however, they can be downloaded from the research center using temperature and humidity data logger software.
The project, funded by DEFRA, will further improve the likelihood of restoring species-rich grasslands and of complying with national biodiversity conservation strategies, but most importantly plants and animals. Contribute to maintenance
The centre for ecological hydrology (CEH) is the UK's leading centre for the scientific study of the land and freshwater environment. The research has covered a wide range of environmental disciplines, from the smallest genes to the entire earth system.
