The document discusses a study evaluating the growth of several ornamental plants in containers using different soilless substrate mixtures. Specifically, it compares a pine bark-based substrate amended with 11% calcined clay particles or sand. The clay-amended substrate resulted in greater growth for some species like hydrangea but not others. It also had improved water and nutrient retention properties compared to the sand-amended substrate. The study demonstrates the potential for clay additions to improve substrate efficiency in container production.

The document summarizes Ireland's experience with peatland restoration. Originally covering 17.2% of Ireland, peatlands have been degraded through turf cutting, industrial extraction, afforestation, and other threats. Restoration projects led by various organizations have rehabilitated over 12,500 hectares of raised bogs and blanket bogs. Ongoing work includes evaluating carbon storage in restored versus degraded sites, with some restored sites found to act as carbon sinks. The document calls for a strategic national restoration plan, more evaluation of restoration results, and recognizing the value of peatlands' ecosystem services to better inform policy and management.

SEPA has legal duties to protect wetlands under various acts relating to water, nature conservation, and flood risk management. This includes groundwater-dependent wetlands, surface water-dependent wetlands, and wetlands designated as SSSIs or part of Natura 2000 sites. Peatlands like blanket bogs, raised bogs and fens are important wetland types that SEPA protects and promotes restoration of due to benefits for water quality, flood management, carbon storage, and biodiversity. Ditch blocking is a key restoration technique but must be done according to guidance to effectively raise water tables and encourage bog vegetation. Mulching cleared peatlands may hinder rather than help restoration by exacerbating issues like nutrient leaching

Environmental threats and Land Reclamation on underground mining of Gem,graph...Pabasara Gunawardane
Removal of valuable minerals from the earth by taking both people and equipment into depths from the earth’s surface is called underground mining.Unsupported openings, Supported openings and Caving methods are the three methods of underground mining. Main methods in Underground mining are drift mining, slope mining, shaft mining, borehole process and hard rock mining.Contamination of rivers, lakes and ground water, alteration of surface and ground water flow, erosion and instability, loss of soil, material contamination, improper sanitation, increased dust, loss of faunal and floral habitats, over use of timber resources and destruction of forests and savannah are the general environmental threats of mining.
Gem mining methods range from digging deep mines and adrift to shallow open mining and river bed mining. In Sri Lanka traditional gem mining is mainly found in Balangoda, Ratnapura, Opanayake, Deniyaya, Rakwana, Elahera and Matale areas. Legislation to minimise environmental damage caused by gem mining is included within the 1971 Act drawn up by the NGJA, reinforced by the Mines and Minerals Act of 1992. Damage to vegetation cover, plantations and paddy fields, damage to land and geomorphology, man-made structures, to streams and river banks, sedimentation and water pollution, damage to fauna, alteration of surface and ground water flow and adverse environmental health conditions are some threats of gem mining.
Graphite and gold mining also have a severe impact on the environment. Especially the impacts are affecting on soil and water.
Backfilling of mined sites, seeding with grasses, tree planting at backfilled sites with native species, shaping and contouring of spoil piles and replacement of top soil are some mitigatory measures to the land reclamation after the mining of gold, gem and graphite. Z.one 2012

Nwrec container workshop i 2006
This document summarizes Jim Owen's approach to measuring and managing substrate properties for container production. Some key points include:
- Engineer substrates to balance water and air content while providing or retaining nutrients. The optimal balance depends on the season, with more water in summer and more air in winter.
- Measure physical properties like total porosity, air space, water holding capacity, and bulk density to characterize substrates. These properties can be affected by container size and shape.
- Common substrate components include bark, peat, coir, compost, and mineral aggregates. The properties of each component and how they blend together impact the final substrate.

Chemical & Microbial analysis of farm & forest soil
The document analyzes and compares the chemical and microbial composition of farm soil and forest soil.
The farm soil had lower organic content than the forest soil but was better suited for plant growth. The forest soil had higher organic content which supported more microorganisms but the acidity levels needed to be adjusted to protect nitrogen-fixing bacteria. Overall, both soils benefited from organic amendments but the farm soil required additional organic matter to support beneficial microbes and earthworms.

It also mentions efforts to improve water quality such as the Golden Gate Canal Diversions, ASR wells, a new landscape/fertilizer ordinance, habitat restoration projects, and educational outreach including rain gardens. The goal is to better manage stormwater and restore seagrass beds and oyster reefs that have declined significantly since the 1950s.
UTSpeaks: Keeping Seas Green
Can preserving humble seagrass help protect us from the extremes of human-induced climate change?
The oceans have long been recognised by science as vital for capturing carbon and renewing the atmospheric balance that preserves life on earth. While vast amounts carbon are captured by phytoplankton, less well known has been the role played by seagrasses in storing carbon, cleansing the air and providing essential habitat for marine life.
Based on latest UTS marine research, this public lecture reveals the essential place of seagrasses in global ecology, the growing threats to its continued viability and the work that is being done to rehabilitate the areas of seagrass habitat already lost.
Professor Bill Gladstone
Marine biologist Bill Gladstone applies scientific understanding to solve problems in marine conservation and environmental management. His interests lie in assessing conservation values in marine ecosystems, the selection and management of marine parks, and community participation in marine conservation. He has worked throughout NSW, the Great Barrier Reef, Torres Strait, the Coral Triangle, and the Middle East.
Dr Peter Macreadie
Marine ecologist Peter Macreadie is a UTS Chancellor’s Postdoctoral Research Fellow. His research cover a wide range of systems; from deep-sea reefs to intertidal oyster reefs. Peter’s current research focuses on seagrasses to better understand how their resilience to climate change can be improved, and how can we capitalise on their ability to capture and store atmospheric carbon.
Professor Peter Ralph
Peter Ralph has been working with seagrasses since the early 90’s, when he pioneered the use of optical methods of measuring photosynthesis to examine the impact of pollution on seagrass health. More recently, he is developing new tools to assess the ability of an entire seagrass meadow to fix carbon. This work is now part of an international research agenda lead by the International Union for Conservation of Nature (IUCN) to demonstrate the importance of seagrasses in the global carbon cycle.

Aquatic Osteoporosis
This document discusses a student experiment investigating the use of recycled shell waste to remediate declining calcium levels in lakes. The student conducted two trials using lake water with low and critical calcium levels, with treatments of 0, 10, and 50 mg of pulverized shell powder added. The experiment found that adding shell powder significantly increased calcium concentrations and improved survival and reproduction of Daphnia pulex. The results suggest that recycling shell waste has potential for restoring calcium levels in lakes and protecting biodiversity.

Presentation outlined how recommendations for effluent disposal on a sodic heavy clay were determined.Impact of Tile Drainage on Manured Land
The summary provides an overview of the key points discussed in the document:
1) The document discusses tile drainage and its potential impacts on water quality, specifically looking at whether liquid manure poses higher risks than synthetic fertilizers and how those risks can be minimized.
2) It outlines the key concepts around soil physics, tile drainage, and its effects on hydrology and water quality. Research shows tile drainage can reduce surface runoff and peak flows while having little impact on total annual flow.
3) The document analyzes nutrient leaching and finds that while tile drainage may increase nutrient transport to surface water, adopting best management practices like controlled drainage and nutrient management can help minimize these risks.
Aquatic Osteoporosis
This experiment tested whether adding pulverized shell waste to calcium-deficient lake water would increase calcium levels and support survival and reproduction of Daphnia pulex. The experiment had two trials with different initial calcium levels and treatments with 0, 10, or 50 mg of shell powder added daily over 21 days. The survival and number of offspring produced by Daphnia pulex in each treatment were recorded and analyzed to determine if shell addition could help restore populations affected by calcium decline in lakes.

Aquatic Osteoporosis: Remediating the emerging problem of lake calcium decline
The document discusses lake calcium decline due to acid rain and other stressors, and describes an experiment testing whether adding pulverized shell waste to calcium-deficient lake water would increase calcium levels and the survival and reproduction of Daphnia pulex. The experiment included two trials testing water with low and critical calcium levels, each with a control and two treatments of 10mg and 50mg of shell powder added. Results showed that shell powder significantly increased calcium levels in both trials but had varying effects on Daphnia pulex, increasing survival in the low calcium trial but decreasing survival and reproduction in the critical calcium trial, suggesting an optimal dosage range.
Peat Restoration: Making Tropical Peat Swamp Forest Ecosystem Alive
This document discusses principles and requirements for restoring degraded tropical peatland ecosystems. It notes that living tropical peatland forests maintain a high water table and accumulation of organic matter, while degraded areas have drainage and fires that cause decomposition to exceed accumulation. Requirements for monitoring and restoring peatlands include mapping location and hydrology, maintaining high water tables, assessing soil and vegetation conditions, and revegetation. Optional advanced monitoring involves subsidence rates, greenhouse gases, water quality, and flora and fauna communities. The key message is that restoration is needed to revive peatland ecosystems and provide environmental benefits, but will require time and natural processes.
