Opportunities and Challenges of Sphagnum Farming & Harvesting
Opportunities and Challenges of Sphagnum Farming & Harvesting Gilbert Ludwig Master’s thesis December 2019 Bioeconomy Master of Natural Resources, Bioeconomy Development Description Author(s) Type of publication Date Ludwig, Gilbert Master’s thesis December 2019 Language of publication: English Number of pages Permission for web 33 publication: x Title of publication Opportunities & Challenges of Sphagnum Farming & Harvesting Master of Natural Resources, Bioeconomy Development Supervisor(s) Kataja, Jyrki; Vertainen, Laura; Assigned by International Peatland Society Abstract Sphagnum sp. moss, of which there are globally about 380 species, are the principal peat forming organisms in temperate and boreal peatlands. Sphagnum farming & harvesting has been proposed as climate-smart and carbon neutral use and after-use of peatlands, and dried Sphagnum have been shown to be excellent raw material for most growing media applications. The state, prospects and challenges of Sphagnum farming & harvesting in different parts of the world are evaluated: Sphagnum farming as paludiculture and after-use of agricultural peatlands and cut-over bogs, Sphagnum farming on mineral soils and mechanical Sphagnum harvesting. Challenges of Sphagnum farming and harvesting as a mean to reduce peat dependency in growing media are still significant, with industrial upscaling, i.e. ensuring adequate quantities of raw material, and economic feasibility being the biggest barriers. Development of new, innovative business models and including Sphagnum in the group of agricultural

A History of Recording Bog Mosses in Berkshire with Selected Site Descriptions A
A History of Recording Bog Mosses in Berkshire with selected Site Descriptions A. Sanders Summary For a paper recently submitted for consideration to the Journal of Bryology, based on my dissertation for an MSc in Biological Recording from the University of Birmingham, I looked at the different methods of detecting change in species distribution over time in relation to bog mosses (Sphagnum spp.) in Vice County 22 (Berkshire). In this paper I will give a brief overview of the history of recording bryophytes (mosses and liverworts) in Berkshire and go on to describe some of the sites I have surveyed, the Sphagnum species to be found there and any changes that have taken place over the known recorded history. Introduction Sphagnum records for Berkshire were collected from a range of sources for my dissertation, as shown in Table 1, including herbaria at The University of Reading, RNG and The National Museum of Wales, NMW; these tended to be from pre-1945 or shortly after and had only a site name for location. The use of herbarium and museum specimens as a source of historical information for education and research, as resources for taxonomic study and as a means of assessing changes in species distribution is well documented (McCarthy 1998, Shaffer et al. 1998, Winker 2004, Pyke & Ehrlich 2010, Godfrey 2011, Colla et al. 2012, Culley 2013, Lavoie 2013, Nelson et al. 2013) and has seen a significant increase in research in the last twenty years (Pyke & Ehrlich 2010) because “collections represent both spatially and temporally precise data, they can be used to reconstruct historical species ranges....” (Drew 2011, p.1250).

IVC) Community Synopsis
Irish Vegetation Classification (IVC) www.biodiversityireland.ie/ivc Community Synopsis Scientific name Betula pubescens – Sphagnum palustre woodland Common name Downy Birch – Blunt-leaved Bog-moss woodland Community code WL4C Vegetation Betula pubescens is the sole constant of the low canopy of this community (mean canopy height = 12.2 m, n = 27). Salix cinerea is the only other tree species likely to be encountered, accompanying Betula in the canopy or forming an understorey. The field layer is often strikingly dominated by tussocks of Molinia caerulea, amongst which can also be found Dryopteris dilatata, Rubus fruticosus agg. and Juncus effusus. A key characteristic is the usual abundance of Sphagnum species in the bryophyte layer, chiefly Sphagnum palustre, but also Sphagnum fimbriatum, Sphagnum capillifolium, Sphagnum recurvum agg. and Sphagnum squarrosum. Thuidium tamariscinum, Scleropodium purum and Hypnum cupressiforme are constants within this layer. Ecology This community comprises open stands of birch woodland on soils with a fairly high water table or a high degree of flushing, typically occurring on basin peats or occasionally on peaty gleys (mean organic content = 83.7%, n = 23). It is often found in peaty hollows at higher altitudes but also included here are stands of intact and degraded raised bog systems in the lowlands (mean altitude = 100 m, n = 26). Consequently, it largely occurs on level ground (mean slope = 0.5°, n = 26). Soils are very acidic and markedly infertile. Sub-communities Two sub-communities have been described for this community. In the Calluna vulgaris-Eriophorum vaginatum sub- community (WL4Ci), bogland species are abundant and Pinus sylvestris may occur.

Record Growth of Sphagnum Papillosum in Georgia (Transcaucasus): Rain Frequency, Temperature and Microhabitat As Key Drivers in Natural Bogs
Record growth of Sphagnum papillosum in Georgia (Transcaucasus): rain frequency, temperature and microhabitat as key drivers in natural bogs M. Krebs, G. Gaudig and H. Joosten Ernst Moritz Arndt University Greifswald, Partner in the Greifswald Mire Centre, Germany _______________________________________________________________________________________ SUMMARY (1) Peatmoss (Sphagnum) growth has been studied widely, in particular at temperate and boreal latitudes > 45 °N, where productivity is mainly controlled by mean annual temperature and precipitation. We studied the growth of Sphagnum papillosum and S. palustre in four peatlands in the year-round warm and humid Kolkheti Lowlands (Georgia, Transcaucasus, eastern end of the Black Sea, latitude 41–42 °N). (2) Productivity, site conditions and climate in Kolkheti are included in a worldwide analysis of studies on the growth of S. papillosum to identify driving factors for its growth. (3) The productivity of S. papillosum and S. palustre under natural conditions is extraordinarily high in Kolkheti, reaching 269–548 g m-2 yr-1 and 387–788 g m-2 yr-1 (mean of various sites), respectively. Rates of increase in length are up to 30.3 cm yr-1, with the largest values for S. palustre. (4) Rate of increase in length and biomass productivity differed between years, with better growth being explained by higher number of rain days and shorter periods without precipitation. Regular rainfall is essential for continuous Sphagnum growth as low water table prevents permanent water supply by capillary rise. (5) The analysis of international studies on Sphagnum papillosum productivity confirms the decisive role of rain frequency, next to microhabitat. Productivity increases further with mean temperature during growth periods, the near-largest values being for Kolkheti.

Mystery of Sphagnum Moss by Sue Bottom, [email protected]
St. Augustine Orchid Society www.staugorchidsociety.org The Mystery of Sphagnum Moss by Sue Bottom, [email protected] Orchid growers have a love hate relationship with sphagnum moss. Those that hate it say it caused their plants to rot, and those that love it have probably learned how to properly water plants growing in it. They’ve learned that you don’t water because it’s Saturday morning, your normal watering day. You water plants growing in sphagnum when the moss approaches dryness. Grower, know thyself. If you have a heavy hand with watering, sphagnum moss may be problematic for you as you will have to struggle not to water your plants until the moss is nearly dry. If your busy schedule keeps you from watering very often, you may have the opposite problem where the moss can become so dry it becomes crusty and is hard to rehydrate. Knowing how sphagnum moss grows in nature gives the orchid grower valuable insights. A living layer of moss grows in carpet-like communities in very wet areas floating on a thick layer of partly rotted plant material. The carpet consists of vertically oriented leafy stems that grow upward while the lower stems become buried, die and ultimately decompose to form beds of peat moss. Sphagnum moss tends to acidify its surroundings having a pH as low as 3, which not many bacteria or fungi can tolerate so decomposition occurs slowly. The sphagnum stems are filled with air spaces and have an impressive water holding potential. The moss grows in a low nutrient environment to which it has adapted by having a high cation exchange capacity largely as a result of its high uronic acid content.
