  • Invertebrates of the River Foss
    Invertebrates of the River Foss A report for the River Foss Society Illustration s of freshwater mussels from Martin Lister’s Historiae Animalium Angliae, published in 1678. Lister was the first naturalist to record invertebrates from the River Foss. Martin Hammond [email protected] December 2017 Introduction Over 170 aquatic invertebrate taxa have been recorded from the River Foss, mostly identified to species level but a few identified only to genus, family or other level. The majority of data are from Environment Agency sampling stations at Marton Abbey, Lilling Green, Strensall, Huntington Church and Castle Mills for the period 1995 to 2016. Few records are available for the upper Foss, where a considerable number of additional species are likely to be found. For a few groups, especially molluscs, older records are available and these provide valuable insights into changes in the ecology of the river. Archaeological investigations from riverside sites in central York also provide some interesting information about the past fauna of the Foss. For example, examination of deposits at Layerthorpe Bridge has revealed statoblasts of the bryozoan Lophopus crystallinus from several samples of fluvial sediment (statoblasts are pods of cells which allow asexual reproduction). These deposits ranged in age from the Anglo-Scandinavian period to the 19th century (Hall et al, 2000), indicating that Lophopus had a very long history of occupation of the lower Foss. The Crystal Moss-animal, to give its English name, is a colonial invertebrate which is a filter-feeder on microscopic algae and bacteria in nutrient- rich, slow-flowing waters. Although once widespread, the Crystal Moss-animal has declined greatly.

  • 2017 City of York Biodiversity Action Plan
    CITY OF YORK Local Biodiversity Action Plan 2017 City of York Local Biodiversity Action Plan - Executive Summary What is biodiversity and why is it important? Biodiversity is the variety of all species of plant and animal life on earth, and the places in which they live. Biodiversity has its own intrinsic value but is also provides us with a wide range of essential goods and services such as such as food, fresh water and clean air, natural flood and climate regulation and pollination of crops, but also less obvious services such as benefits to our health and wellbeing and providing a sense of place. We are experiencing global declines in biodiversity, and the goods and services which it provides are consistently undervalued. Efforts to protect and enhance biodiversity need to be significantly increased. The Biodiversity of the City of York The City of York area is a special place not only for its history, buildings and archaeology but also for its wildlife. York Minister is an 800 year old jewel in the historical crown of the city, but we also have our natural gems as well. York supports species and habitats which are of national, regional and local conservation importance including the endangered Tansy Beetle which until 2014 was known only to occur along stretches of the River Ouse around York and Selby; ancient flood meadows of which c.9-10% of the national resource occurs in York; populations of Otters and Water Voles on the River Ouse, River Foss and their tributaries; the country’s most northerly example of extensive lowland heath at Strensall Common; and internationally important populations of wetland birds in the Lower Derwent Valley.

  • North Yorkshire Joint Strategic Needs Assessment 2019 Vale of York CCG Profile
    January 2019 North Yorkshire Joint Strategic Needs Assessment 2019 Vale of York CCG Profile Introduction This profile provides an overview of population health needs in Vale of York CCG (VoY CCG). Greater detail on particular topics can be found in our Joint Strategic Needs Assessment (JSNA) resource at www.datanorthyorkshire.org. This document is structured into five parts: population, deprivation, disease prevalence, hospital admissions and mortality. It identifies the major themes which affect health in VoY CCG and presents the latest available data, so the dates vary between indicators. Summary Life expectancy is higher than England. For 2011-2015, female life expectancy in VoY CCG is 83.6 years (England: 83.1), and male life expectancy is more than three years lower than for females at 80 years (England: 79.4) [1]. There is a high proportion of older people. In 2017, 19.6% of the population was aged 65 and over (68,900), higher than national average (17.3%). Furthermore over 9,100 (2.6%) were age 85+, compared with 2.3% in England. [2] Some children grow up in relative poverty. In 2015, there were 11.2% of children aged 0-15 years living in low income families, compared with 19.9% in England [1]. There are areas of deprivation. Within the CCG area, 7 Lower Super Output Areas (LSOAs) out of a total of 206 are amongst the 20% most deprived in England, and one these LSOAs is amongst the 10% most deprived in England. This is in Selby West ward in Selby District. [3] Many people have longstanding health problems.

  • Part 1 Rea Ch Classifica Tion
    RIVER QUALITY SURVEY NATIONAL RIVERS AUTHORITY NORTHUMBRIA & YORKSHIRE REGION GQA ASSESSMENT 1994 PART 1 REA CH CLASSIFICA TION FRESHWATER RIVERS AND CANALS VERSION 1: AUGUST 1995 GQA ASSESSMENT 1994 \ NORTHUMBRIA & YORKSHIRE REGION To allow the development of a National method of evaluating water quality, the rivers in all the NRA regions of England and Wales have been divided into reaches, which are numbered using a coding system based on the hydrological reference for each river basin. Each classified reach then has a chemistry sample point assigned to it and these sample points are regularly monitored for Biochemical Oxygen Demand (BOD), Dissolved oxygen (DO) and Total Ammonia. The summary statistics calculated from the results of this sampling are sent to a National Centre where the GQA Grades are calculated. A National report is produced and each region can then produce more detailed reports on the quality of their own rivers. For Northumbria and Yorkshire Region, this Regional Report has been divided into two parts. PARTI: REACH CLASSIFICATION This report contains a listing of the river reaches within the region, with their start and finish grid reference, approximate length, and the 1990 and 1994 GQA class for each reach. The reference code of the chemistry sample point used to classify the reach is also included. A sample point may classify several reaches if there are no major discharges or tributaries dividing those reaches. The sample point used to classify a reach may change and the classification is therefore calculated using the summary statistics for each sample point that has been used over the past three years.

  • The Foss Navigation at Strensall (From the River Foss Society)
    The Foss Navigation at Strensall (from the River Foss Society) Discussions to build the Foss Navigation from York to Stillington began in 1791, and in 1793 work commenced in constructing the canal in York. By 1805-06 the canal was built and opened as far as Sheriff Hutton Bridge. Lime, coal and building materials were the main cargoes carried upstream, whilst timber and farm produce were the main cargo carried downstream. Tanneries were also served by the canal. During its brief life the Navigation suffered from lack of water, this was due to the main source of water, Pond Head reservoir, being situated too far away between the villages of Oulston and Yearsley in the Howardian Hills, a distance of some twelve miles. The coming of the York to Scarborough railway in 1845 spelt the end of the canal as a commercial concern, income from cargo carried was down and in 1852 The Foss Navigation was sold to the York Corporation and an Act was obtained to abandon the Navigation and it fell into disrepair, apart from a short distance in the centre of York. The industrial archaeology of the Foss Navigation Canal can be clearly seen in Strensall village approximately six miles upstream from the City of York. The river Foss having canalised up to this point for the carriage of cargoes. Evidence of the canal include: The iconic canal bridge, a dry dock for the transfer of cargo, two locks, one low level, and one double high rise lock, together with the site of the lock keepers house.

  • Community Profile: Foss
    Community Profile: Foss This area cover the stretch of the River Foss from Piccadilly all the way upstream to Earswick. It also covers South Beck, and Westfield Beck up to Wigginton. The main river extent on the River Foss reaches up to Yearsley Bridge. Upstream of this location the River Foss is designated ordinary watercourse and is located within the Foss Internal Drainage Board area. As such, it is managed by the of the Internal Drainage Board. There are no flood defences in this area. Flood warning services are provided for the Foss at properties on Huntington Road, Haley's Terrace, Yearsley Crescent, The Groves, Foss Bank and properties surrounding Wormalds Cut and Foss Navigation. There are emergency plans in place for Wigginton, Haxby and New Earswick, however there are currently no flood wardens within this area We estimate that around 610 residential properties are currently at risk of flooding from the River Foss within this area during a 1% (1 in 100 year) flood event. This may rise to 730 due to climate change. As part of the River Foss Model Improvements project in 2009, a study to investigate the feasibility of flood storage on Westfield Beck, primarily by utilising data from the previous study together with additional modelling. Conclusion from the report included that to prevent flooding the peak water level at the New Earswick culvert should be maintained. Furthermore, there were no sites with ground levels suitable for natural storage and it will be necessary to excavate a storage pond. A preferred site for a pond was identified on the left bank of Westfield Beck, between the York and Scarborough railway line and Haxby Road.
