Manchester Mosslands SAC Astley and Bedford Moss, Holcroft Moss, Risley Moss

This is the report on Habitats Directive, the Review of Consents Stage 1 and 2 by the Environment Agency of the Manchester Mosslands cSAC, Astley and Bedford Moss, Holcroft Moss and Risley Moss. The Habitats Directive has the main aim to promote the maintenance of biodiversity by defining a common framework for the conservation of wild plants and animals and habitats of community interest. The Directive establishes a European ecological network known as "Natura 2000". The network comprises Special Areas of Conservation (SAC) and Special Protection Areas (SPA). In the section on Stage 1 or Screening Process of the Habitat Directive, it is identified the likely impacts upon the Manchester Mosslands cSAC, Astley and Bedford Moss, Holcroft Moss and Risley Moss of a project, plan or activities, either alone or in combination with other projects, plans or activities, and considers whether these impacts are likely to be significant. In the section on Stage 2 or Appropiate Assessment of the Habitat Directive, it is considered the impact on the integrity of the Manchester Mosslands cSAC, Astley and Bedford Moss, Holcroft Moss and Risley Moss of the projects, plans or activities, either alone or in combination with other projects, plans or activities, with respect to the site’s structure and function and its conservation objectives. Additionally, where these are adverse impacts, an assessment of the potential mitigation of those impacts. The criteria used in this report to identify relevant projects, plans or activities and their impacts are water quality discharge consents, waste management licences, abstraction licences, Integration Pollution Control (IPC) and Integrated Pollution Prevention Control (IPPC) permits. Proformas, hydrogeological and GIS maps are included in the review.

A hydrogeological assessment of Wybunbury Moss

This is a technical report of a hydrogeological assessment by the Environment Agency, an assessment to inform the Stage 3 review of Consents under the Habitats Directive for Wybunbury Moss, a National Nature Reserve and Special Area of Conservation in Cheshire. In the Stage 2 Review of Consents, one groundwater licence could not be clearly assessed as having no significant impact and so was taken forward to Stage 3. Further work has been carried out to refine the understanding of groundwater flow and the extent of the actual groundwater catchment of Wybunbury Moss, including three drilled boreholes, the monitoring of groundwater levels in the boreholes by data-loggers for more than 18 months and the sampling and analysis of the groundwater from the boreholes. Results of this further work are shown in Appendixes. From this work, a geological cross-section and Conceptual Model has been produced, and a map showing the revised understanding of the groundwater catchment of Wybunbury Moss. It also includes in Appendix I, the Stage 2 Review of Consents previously made.

Monitoring report: sand dune reconstruction and restoration, at the Moss Landing Marine Laboratories

The Plan for Sand Dune Reconstruction and Restoration (and Biological Assessment) at Moss Landing Marine Laboratories (ABA Consultants, April 1, 1992) described reconstruction of dune contours and biological restoration with native dune plants to be carried out over the 8 acre site formerly occupied by the marine labs (prior to the Loma Prieta earthquake of October 1989). The plan called for annual reports in letter form which would present data on plant abundance, a short narrative description of changes on the site, progress towards recovery of the plant community, and assessment of progress based on restoration goals and further steps to be taken. This monitoring report [dated April 25, 1994] addresses those points and also contains a summary of other activities integral in dune restoration -- education, public participation, school and conservation organization field trips, as well as the associated activities of restoration, plant collecting, propagation, and weed control.

Morphological Adaptations to Drought and Reproductive Strategy of the Moss Syntrichia caninervis in the Gurbantunggut Desert, China

The biological soil crusts (BSCs) in the Gurbantunggut Desert, the largest fixed and semi-fixed desert in China, feature moss-dominated BSCs, which play an indispensable role in sand fixation. Syntrichia caninervis Mitt. (S. caninervis) serves as one of the most common species in BSCs in the desert. In this study we examined the morphological structure of S. caninervis from leafy gametophyte to protonema using light and scanning electron microscopy (SEM). We also examined the relationships between the morphological structure of S. caninervis and environmental factors. We found that: (1) this moss species is commonly tufted on the sand surface, and its leaves are folded upwards and twisted around the stem under dry conditions; (2) the cells on both upper and lower leaf surfaces have C-shaped dark papillae, which may reflect sunlight to reduce the damage from high temperature; (3) the leaf costa is excurrent, forming an awn with forked teeth; and (4) the protonema cells are small and thickset with thick cell walls and the cytoplasm is highly concentrated with a small vacuole. In addition, we also found that the protonema cells always form pouches on the tip of the mother cells during the process of cell polarization. Our results suggest that S. caninervis has, through its life cycle, several morphological and structural characteristics to adapt to dry environmental conditions. These morphological features of S. caninervis may also be found in other deserts in the world due to the world-wide distribution of the species.

Strong temperature dependence and no moss photosynthesis in winter CO2 flux for a Kobresia meadow on the Qinghai-Tibetan plateau

We examined the CO2 exchange of a Kobresia meadow ecosystem on the Qinghai-Tibetan plateau using a chamber system. CO2 efflux from the ecosystem was strongly dependence on soil surface temperature. The COZ efflux-temperature relationship was identical under both light and dark conditions, indicating that no photosynthesis could be detected under light conditions during the measurement period. The temperature sensitivity (Q(10)) of the COZ efflux showed a marked transition around -1.0 degrees C; Q(10) was 2.14 at soil surface temperatures above and equal to -1.0 degrees C but was 15.3 at temperatures below -1.0 degrees C. Our findings suggest that soil surface temperature was the major factor controlling winter COZ flux for the alpine meadow ecosystem and that freeze-thaw cycles at the soil surface layer play an important role in the temperature dependence of winter CO2 flux.
