THE EXPERIMENTAL USE of VARIOUS COVERS and NATIVE TRANSPLANTS for the REVEGETATION of the KAM-KOTIA TAILINGS SITE, TIMMINS, ONTARI01 by Keith Winterhalder2 THE EXPERIMENTAL USE OF VARIOUS COVERS AND NATIVE TRANSPLANTS FOR THE REVEGETATION OF THE KAM-KOTIA TAILINGS SITE, TIMMINS, ONTARI01 by Keith Winterhalder2 Abstract. The Kam-Katia mine/mill complex was closed in 1972, leaving 275 hectares of sulphide-rich, acid-generating tailings. Surface tailings have a pH of around 2.5, and contain elevated levels of arsenic, zinc and copper. Preliminary revegetation field trials have investigated the effectiveness of covers such as gravel, loam and peat, at different depths and in different combinations, and of locally available neutralizing agents such as ground dolomitic limestone, marl and sewage incinerator ash. The survival and growth of a seeded grass-legume mixture on replicated 2 m x 2 m plots has been monitored for a one-year period, as has the surface moisture regime and the capillary rise of acid ground-water. Plant biomass data show that a loam covering or a gravel covering topped with loam are the most effective, but at least one more season of observation will be required to determine the relative vulnerability of different cover combinations to upward movement of acids. A second approach to revegetation has been the transplanting of metal-tolerant ecotypes of native species from acid, metal- contaminated soils of the Sudbury mining area such as Oeschampsia caespitosa (Tufted Hairgrass}, Agrostis gigantea (Redtop}, Scirpus cyperinus (Wool Sedge} and Betula pumila (Dwarf Birch}. Tufted Hairgrass, Redtop and Dwarf Birch proved to be most successful on well-drained microsites, the Wool Sedge doing better on moist sites. A third approach involved the transplantation of whole sods of peat and associated plants from a nearby bog, with considerable success. While this approach may not be feasible on an operational scale under current circumstances, in view of the expense and the concomitant destruction of a natural bog community, the situation will change if current plans to develop the horticultural peat industry in Northern Ontario come to fruition. ------------ .------------------------- Introduction requires a more complex solution.

Zehetmayr Senior Officer for Wales, Forestry Commission Forestry Commission 1979 FOREWORD This paper is the record of thirty years work on planting in Wales, carried out by the Forestry Commission outwith its main remit for growing timber. Most of the reclamation of derelict land or tips and much of the planting has been financed by Government Agencies or Local Authorities and much of the resulting plantation has been or will be incorporated into the Commission's Forests. The initiative for this paper came from a review for the Prince of Wales' Committee, the objective of which is to conserve and enhance the Welsh environment, both rural and urban. A general summary prepared by J.W.L. Zehetmayr (Senior Officer for Wales, Forestry Commission) served as the basis for a detailed study by K.F. Broad (Research and Development Division, Forestry Commission, in 1974-75, which forms the main text. It seems likely that the Forestry Commission will continue with such work for many years, particularly in South Wales, given the continued drive to clear dereliction and at the same time to step up opencast working. 2 CONTENTS Page INTRODUCTION 5 Chapter 1.

  • HEREFORDSHIRE Is Repeatedly Referred to in Domesday As Lying In
    ABO BLOOD GROUPS, HUMAN HISTORY AND LANGUAGE IN HEREFORDSHIRE WITH SPECIAL REFERENCE TO THE LOW B FREQUENCY IN EUROPE I. MORGAN WATKIN County Health Department, Aberystwyth Received6.x.64 1.INTRODUCTION HEREFORDSHIREis repeatedly referred to in Domesday as lying in Wales and the county is regularly described as such in the Pipe Rolls until 1249-50. Of the two dozen or so charters granted to the county town, a number are addressed to the citizens of Hereford in Wales. That fluency in Welsh was until 1855oneof the qualifications for the post of clerk to the Hereford city magistrates indicated the county's bilingual nature. The object of the present investigation is to ascertain whether there is any significant genetic difference between the part of Herefordshire conquered by the Anglo-Saxons and the area called "Welsh Hereford- shire ".Assome moorland parishes have lost 50 per cent. of their inhabitants during the last 50 years, the need to carry out the survey is the more pressing. 2.THE HUMAN HISTORY OF HEREFORDSHIRE Pre-Norman Conquest Offa'sgeneral line of demarcation between England and Wales in the eighth century extending in Herefordshire from near Lyonshall to Bridge Sollars, about five miles upstream from Hereford, is inter- mittent in the well-wooded lowlands, being only found in the Saxon clearings. From this Fox (i) infers that the intervening forest with its dense thickets of thorn and bramble filling the space under the tree canopy was an impassable barrier. Downstream to Redbrook (Glos.) the river was probably the boundary but the ferry crossing from Beachley to Aust and the tidal navigational rights up the Wye were retained by the Welsh—facts which suggest that the Dyke was in the nature of an agreed frontier.

    Swansea Canal Clydach to Pontardawe Playing Fields Restoration Feasibility Study Swansea Canal Society 2013 Swansea Canal Clydach to Pontardawe Playing Fields Restoration Feasibility Study Client: Swansea Canal Society Funding: Inland Waterways Association Prepared By Patrick Moss Jennifer Smith Tamarisk Kay Nick Dowling Authorised for Issue By Patrick Moss Moss Naylor Young Limited 5 Oakdene Gardens Marple Stockport SK6 6PN Town Planning, Transport Planning, Waterway Regeneration Executive Summary This report, prepared by Moss Naylor Young Limited, has been commissioned by the Swansea Canal Society to examine a proposal to restore the Swansea Canal between Clydach and Trebanos. It examines at outline level the practicality, cost and potential benefits of restoration of the Swansea Canal from Clydach to Trebanos. This length of approximately four kilometres is assessed as a free standing scheme although it could also form part of the restoration of a longer length of canal if that were to proceed. This study has used as its core baseline document the Feasibility Report undertaken by WS Atkins in 2002. The genesis of this latest project is an apparent opportunity to reclaim the line of the canal through a depot site just to the east of the town of Clydach. The restoration is straight forward from an engineering perspective: the only significant obstacle is the infilling of the canal route across the depot site, and the canal line is more or less clear across this. The works to conceal the lock have, as far as can be ascertained, also worked to preserve it. Re-excavation of the canal and the lock would result in a continuous waterway linking the canal either side of the site.

  • 2. Urban Geology of Swansea and Port Talbot
    Waters et al . Urban geology of Swansea and Port Talbot 2. Urban geology of Swansea and Port Talbot Waters, C N, Price, S J, Davies, J, Tye, A M, Brown, S E & Schofield, D I The conurbation of Swansea–Neath–Port Talbot is one of the main centres of industrial development in South Wales. A long history of mineral extraction and processing, which stoked the initial growth of the towns, declined during the 20 th Century. Many of these former industries have left a legacy of groundwater, water- course and land contamination. A project funded by the Environment & Hazards Directorate (British Geological Survey) between 2000-2005 used available geological data to determine potential areas of contaminated land and understand the influence of the geology to pollutant pathways (Waters et al ., In press a). The study covered 100 km 2 of the Swansea- Neath-Port Talbot area (Fig. 2.1) and was aimed at providing data relevant to contaminated land issues, to augment the study by Arup (1997) on earth science information relevant to planning and development for the Swansea-Llanelli district, and look at new methodologies of presenting the data. Contaminated land is defined as areas where a Source-Pathway-Receptor linkage can be established (DoE, 1995). In order to determine Source areas it is necessary to appreciate the industrial development of the region by collecting information on current and former land use and the extent and nature of artificial deposits. The degree that contamination of Source areas is a problem can be established from analysis of soil geochemistry. The Pathway component represents the migration of contaminants through the air, surface water or groundwater.

'rrnation Centre !. ' od Office No ENVIRONMENT AGENCY Mrfoo No BLfiK 092011 <a£ & ? S C INTRODUCTION The rivers, lakes, estuaries and coastal waters of Wales are subject to large and rapidly increasing demands from the users of water. Many different uses interact, or compete for water or water space, and will inevitably come into conflict with one another. The National Rivers Authority (NRA) was created in 1989 as an independent environmental watchdog. Its prime purpose is to maintain and improve the water environment and regulate the use of water by industry, agriculture and the private water and sewerage companies. The N RA ’s general duties include: Maintenance and improvement of water quality by control of pollution in surface and groundwater. Flood defence for people and property. Flood warning. Management of water resources. Maintenance and improvement of fisheries. Conservation of the natural water environment. Promotion of water based recreation. Navigation (in some rivers). In addition, the NRA has a responsibility to reconcile conflicts between water users and plays a key role in the strategic management of the interaction between users of the water and land environments. We believe it is important that the interests of all water users are considered in the developm ent and protection of the water environment and have consequently chosen to promote our vision and management proposals via published Catchment Management Plans (CMPs).
