Ecological Assessment Land Off New Line, Bacup Ecological Assessment Land off New Line, Bacup Report reference: BE-R-1096-01 September 2011 Report Title: Ecological Assessment Land off New Line, Bacup Report Reference: BE-R-1096-01 Written by Michelle Dickinson BSc (Hons) MSc MIEEM Ecologist Technical review: Peter James Brooks BSc (Hons) MA MIEEM CEnv Director QA review: Peter James Brooks BSc (Hons) MA MIEEM CEnv Director Approved for issue Peter James Brooks BSc (Hons) MA MIEEM CEnv Director Date: 19.10.11 High Street House, 2 High Street, Yeadon, Leeds, LS19 7PP Phone 0113 250 6101 Fax 0113 250 6944 Email: [email protected] Registered in England Number 5351418 www.brooks-ecological.co.uk Summary Statement The site has been found to be of low conservation value. There is potential for a badger sett to be present within 30m of the site, but not within it, and therefore a badger survey has been recommended. The application site itself holds no suitable habitat for any other protected species which may be present within the surrounding area and therefore no other further surveys at this point are required. The site has been found to contain invasive species which will need to be removed by a licensed contractor. General recommendations in terms of preventing impacts on the adjacent watercourse, as well as enhancing the site’s biodiversity are made in the report. Land off New Line, Bacup Introduction Brooks Ecological Ltd was commissioned by Harron Homes to carry out an ecological assessment of land off New Line, Bacup, Lancashire (SD 878215). Figure 1: Application Site Boundary Site Proposals The proposal is for a residential development on previously developed land. Potential impacts The following potential impacts are highlighted and the report which follows sets out the significance of these impacts relative to the ecological value of the site and the potential presence of protected or notable species: Excavation and site clearance works Effects on adjacent habitats Desk Study A desk study was carried out to identify species or habitats that are considered important in a local context and to identify any species recorded locally that may be associated with the application site. This information can be used to help target groups that need to be considered in more detail in order to identify the ecological baseline for the application site. 2 September 2011 Ecological Assessment Land off New Line, Bacup Designated Sites A search of the MAGIC website was undertaken. The MAGIC site is a Geographical Information System that contains all statutory (e.g. Sites of Scientific Interest [SSSI’s]) as well as many non-statutorily listed habitats (e.g. Ancient woodlands and grassland inventory sites). It is a valuable tool when considering the relationship of a potential development site with nearby important habitats. There is one statutorily designated site for nature conservation within 2 km of the application site; This is Lee Quarry Site of Special Scientific Interest (SSSI) approximately 950m to the south-west of the application site. This site has been designated for its geological interest and is beyond the scope of this report. Lancashire Environment Record Network has provided records for three locally designated sites within 2km of the application site, these are: Taddy Lodge Biological Heritage Site (BHS) – c1.2km south-east of the application site. Reaps Moss BHS – c.1.4km north-east of the site. Lee Quarry BHS – c.950m south-west. Due to the nature of the proposed works, and distance from these sites, it is considered that no nationally or locally designated sites for nature conservation will be impacted on by the development. English Nature Natural Area The site falls within Natural Area 36 Southern Pennines Natural area 36 is characterised by large scale sweeping landform with an open character created by exposed gritstone moors at an altitude of 400-450m, deeply trenched by narrow valleys and wooded cloughs. There are mosaics of mixed heather moorland and blanket bog with rough pasture. The landscape contains habitats of European importance, being: Blanket bogs Heather moorland Wet heath There are also ecologically-rich acid flushes, wooded cloughs and existing woodlands. 3 September 2011 Ecological Assessment Land off New Line, Bacup The application site does not contain examples of the above significant habitats. Local Biodiversity Action Plan The site is covered by the Lancashire Biodiversity Action Plan. Under this BAP plans have been created for the species or groups listed in Table 1.

A stream runs through a steep-sided narrow gorge to the south of the site which enters a lake c.150m to the west. The site is located along the southern edge of Bacup within the Rossendale Valley. To the west and east run linear villages containing a number of mills. To the south of the site rises the Pennine Moors supporting a number of quarries. Records The local Data holder, Lancashire Environment Record Network (LERN), was asked to provide information on protected or notable species within 2 km of the application site. Records have been provided for badger c.1.6km north-east of the site and an unidentified newt species c.1.7km to the south-west, both in 1998. A number of records for priority species under the Lancashire Biodiversity Action Plan were also provided, being; raven, golden-ringed dragonfly, emperor dragonfly, merlin, common frog, heath spotted orchid, as well as a number of farmland birds including skylark, lapwing, curlew and twite. None of these records were from within the application site. 5 September 2011 Ecological Assessment Land off New Line, Bacup Phase 1 Habitat Survey Survey Method The survey was carried out on the 14th September 2011 by an experienced field ecologist who is a full member of the Institute of Ecology and Environmental Management (IEEM). The survey followed a Phase 1 habitat survey methodology (JNCC, 1993) and was extended to assess faunal potential. This involves walking the site, mapping and describing different habitats (for example: woodland, grassland, scrub). Evidence of fauna and faunal habitat is also recorded (for example droppings, tracks or specialist habitat such as ponds for breeding amphibians). This modified approach to the Phase 1 survey is in accordance with the approach recommended by the Guidelines for Baseline Ecological Assessment (IEA, 1995). Results The application site comprises predominantly marshy grassland colonising crushed demolition material. There are a small number of scattered, young, broadleaved trees to the site edges and several piles of grassed, and bare, rubble to the eastern section. A small ponded area also exists within this section. The site is relatively level with a large depression colonised by coarse grasses in the western section. A culverted drain emerges into the site briefly at its northern boundary and is possibly linked to the culvert which emerges just south of the site. Whilst Figure 1 shows there to be a number of buildings within the site, these are no longer present. The site was found to support the following habitats: Marshy grassland Culverted drain Pond Marshy Grassland The site has been capped with crushed demolition material and since has become colonised by marshy grassland species and mosses (Figure 2). The vegetation across this site is sparse in places where uncolonised patches of hardcore are present. 6 September 2011 Ecological Assessment Land off New Line, Bacup Common, coarse, grasses noted within this grassland include cocks-foot (Dactylis glomerata), tufted hair-grass (Deschampsia cespitosa), Yorkshire fog (Holcus lanata), sheeps fescue (Festuca ovina), timothy (Phleum pratense), canary reed grass (Phalaris arundinacea) creeping bent (Agrostis stolonifera) and other bent species (Agrostis spp.). Marshy grassland species, such as rushes are abundant across the main body of the site including soft rush (Juncus effusus), compact rush (Juncus conglomeratus), jointed rush (Juncus articulatus), hard rush (Juncus inflexus) and marsh thistle (Cirsium palustre) as well as mosses including pointed spear moss (Calliergonella cuspidata). Towards the depressed western section of the site the grassland becomes more rank with a higher diversity of forb and tall herb species (Figure 3).

  • Impatiens Glandulifera (Himalayan Balsam) Chloroplast Genome Sequence As a Promising Target for Populations Studies
    Impatiens glandulifera (Himalayan balsam) chloroplast genome sequence as a promising target for populations studies Giovanni Cafa1, Riccardo Baroncelli2, Carol A. Ellison1 and Daisuke Kurose1 1 CABI Europe, Egham, Surrey, UK 2 University of Salamanca, Instituto Hispano-Luso de Investigaciones Agrarias (CIALE), Villamayor (Salamanca), Spain ABSTRACT Background: Himalayan balsam Impatiens glandulifera Royle (Balsaminaceae) is a highly invasive annual species native of the Himalayas. Biocontrol of the plant using the rust fungus Puccinia komarovii var. glanduliferae is currently being implemented, but issues have arisen with matching UK weed genotypes with compatible strains of the pathogen. To support successful biocontrol, a better understanding of the host weed population, including potential sources of introductions, of Himalayan balsam is required. Methods: In this molecular study, two new complete chloroplast (cp) genomes of I. glandulifera were obtained with low coverage whole genome sequencing (genome skimming). A 125-year-old herbarium specimen (HB92) collected from the native range was sequenced and assembled and compared with a 2-year-old specimen from UK field plants (HB10). Results: The complete cp genomes were double-stranded molecules of 152,260 bp (HB92) and 152,203 bp (HB10) in length and showed 97 variable sites: 27 intragenic and 70 intergenic. The two genomes were aligned and mapped with two closely related genomes used as references. Genome skimming generates complete organellar genomes with limited technical and financial efforts and produces large datasets compared to multi-locus sequence typing. This study demonstrates the 26 July 2019 Submitted suitability of genome skimming for generating complete cp genomes of historic Accepted 12 February 2020 Published 24 March 2020 herbarium material.

  • Is the Spread of Non-Native Plants in Alaska Accelerating?
    Meeting the Challenge: Invasive Plants in Pacific Northwest Ecosystems IS THE SPREAD OF NON-NATIVE PLANTS IN ALASKA ACCELERATING? Matthew L. Carlson1 and Michael Shephard2 ABSTRACT Alaska has remained relatively unaffected by non-native plants; however, recently the state has started to experience an influx of invasive non-native plants that the rest of the U.S. underwent 60–100 years ago. With the increase in population, gardening, development, and commerce there have been more frequent introductions to Alaska. Many of these species, such as meadow hawkweed (Hieracium caespitosum), Canada thistle (Cirsium arvense), and spotted knapweed (Centaurea biebersteinii), have only localized populations in Alaska. Other species such as reed canary grass (Phalaris arundinacea) and white sweetclover (Melilotus officinalis), both formerly used in roadside seed mixes, are now very widespread and are moving into riparian areas and wetlands. We review the available literature and Alaska’s statewide invasive plant database (AKEPIC, Alaska Exotic Plant Clearinghouse) to summarize changes in Alaska’s non-native flora over the last 65 years. We suggest that Alaska is not immune to invasion, but rather that the exponential increase in non-native plants experienced else- where is delayed by a half century. This review highlights the need for more intensive detection and rapid response work if Alaska is going to remain free of many of the invasive species problems that plague the contiguous U.S. KEYWORDS: Alaska, invasion patterns, invasive plants, non-native plants, plant databases.

  • Ecological Characteristics of Invasive Alien Plants John H
    This file was created by scanning the printed publication. Errors identified by the software have been corrected; however, some errors may remain. Ecological Characteristics of Invasive Alien Plants John H. Brock1 ABSTRACT An influx of alien plant material to the North American flora accompanied the settlement of the continent by immigrant peoples during the latter part of the 19th century. Plant materials were introduced as ornamentals, agronomic crops, land conseNation material, and many were accidentally introduced as contaminants in seeds of desirable plants such as small grain crops. In the early 20th century introductions continued as people wanted to improve on the natural vegetation, and have plants that seemed to be better adapted to habitats than were components of the native flora. Several of these well-intended introductions are now considered as invasive. This paper presents information about some of the general characteristics of invasive plants including: pollination strategies, regeneration strategies, seed and propagule dispersal, formation of ecotypes, the lag time from introduction until the plant is termed invasive, and some aspects of the physiology of invasive plants. Many alien plants have naturalized to the environment of North America, and are so widespread that vegetation management strategies to control the whole population are probably not feasible. However, strategies to control the further invasion by the alien species are needed and will most likely incorporate integrated weed management techniques that are socially and politically acceptable. INTRODUCTION When taking a global view, there is a question among plant ecologists if a species is ever truly an "alien". However, in studying invasion ecology, an introduced species of a flora must be treated as alien to an ecosystem because it would not be there without human inteNention (Pysek 1995).
