Colchester Natural History Society
COLCHESTER NATURAL HISTORY SOCIETY COLCHESTER BOROUGH COUNCIL (CBC) LOCAL PLAN EXAMINATION MAIN MATTER 6 SOUTH COLCHESTER POLICY SC2 MIDDLWICK RANGES 1. In August 2017 Colchester Natural History Society (CNHS) responded to the CBC Draft Local Plan by acknowledging the policy plan to review the Middlewick ecology. In August 2019 in response to a ‘masterplan consultation’ CNHS opposed development citing species rarity and closeness to SSSI sites and added that as the Local Plan at that time had not been examined the masterplan consultation was premature. 2. CBC’s narrative supporting Local Plan Policy SC2: Middlewick Ranges, acknowledges that the site is a designated Local Wildlife Site (LOW). (Previously LoWS’s were titled SINC’s – Sites of Importance for Nature Conservation, a more accurate description of their function). The CBC narrative adds “3.3.2 Middlewick Ranges is a Local Wildlife Site (LoWS) dominated by acid grassland primarily designated for this and its invertebrate populations, but with important scrub, scattered trees and copses and hedgerows. Birch Brook LoWS to the south of the site supports the brook itself and mixed broadleaf and wet woodland, with some characteristics of ancient woodland. The habitats within the site are of high (up to County) biodiversity value, including approximately 53 Ha of acid grassland. The site supports a range of protected species such as invertebrates, breeding birds and bats.” 3. An independent report by Midland Ecology which is an appendix to this submission identifies seven nationally threatened and eight nationally scarce species. 4. The Midland Ecology report paragraph 3.3 makes the point that an important function of Local Wildlife Sites is to “complement or buffer statutory conservation sites (SSSIs)”. -

Threatened Species Translocation Plan Button Wrinklewort (Rutidosis
Threatened Species Translocation Plan Button Wrinklewort (Rutidosis leptorrhynchoides) Summary Button wrinklewort Rutidosis leptorrhynchoides is a perennial wildflower that grows in grasslands and woodlands in Victoria, NSW and the ACT. There are only 29 known extant populations of the species left and only 8 that contain 5000 or more plants. The species is listed as endangered both nationally (EPBC Act 1999) and locally (Nature Conservation Act 2014). Increasing the number of populations through the establishment of new, self-sustaining populations is identified as a key management objective for the preservation of R. leptorrhynchoides in perpetuity in the wild (ACT Government 2017). The translocation will be undertaken at the Barrer Hill restoration area (Molonglo River Reserve, ACT). The restoration area supports potentially suitable habitat, is within the species known range and is believed to have supported R. leptorrhynchoides in the past. Furthermore, the Molonglo River Reserve is recognised as a biodiversity offset with significant and ongoing funding committed to the restoration, protection and ongoing management of reserve. Objectives To establish a new, self-sustaining, genetically diverse population of Rutidosis leptorrhynchoides within the Molonglo River Reserve that is capable of surviving in both the short and long term.

Spatial and Temporal Variability of Carbon Stocks Within the River
Spatial and temporal variability of carbon stocks within the River Colne Estuary By Leila Tavallali University of Essex A thesis submitted for the degree of Doctor of Philosophy (PhD) Department of Biological sciences University of Essex February 2018 2 Abstract Saltmarshes are one of the most significant blue carbon sinks but there is a paucity of information regarding saltmarsh carbon stocks globally, consequently these habitats are not included in the global carbon budget. The aim of this study is therefore to better understand the spatial and temporal variation of saltmarsh sediment total organic carbon (TOC) content. Therefore, three saltmarshes along the salinity gradient of the Colne Estuary were studied. The effect of the study sites’ locations along the estuary, higher plant species distribution, above-ground biomass and aerobic respiration on TOC content was investigated. The spatial and temporal variation of sediment TOC content was investigated by monthly sampling from two habitats and three zones at each study site. There was a significant spatial variation in plant species distribution which could be due to zonation and the location of the sites along the estuary. Saltmarsh plants were the important driver of spatial and temporal variations in sediment TOC content. The sediment TOC content at the study sites in the lower (Colne Point) and the mid (Brightlingsea) estuary was significantly higher than the upper estuary (Wivenhoe) (P < 0.001, range: 9-25 Kg C m-2). The range of sediment TOC content of the studied saltmarshes was between 88% - 290% higher than other UK studied saltmarshes and between 4% -169% higher than the majority of the studied marshes in the Northern Hemisphere. -

Molecular Approaches in Natural Resource Conservation and Management
MOLECULAR APPROACHES IN NATURAL RESOURCE CONSERVATION AND MANAGEMENT Recent advances in molecular genetics and genomics have been embraced by many scientists in natural resource conservation. Today, several major conservation and management journals are using the “genetics” editors of this book to deal solely with the influx of manuscripts that employ molecular data. The editors have attempted to synthesize some of the major uses of molecular markers in natural resource management in a book targeted not only at scientists but also at individuals actively making conservation and management decisions. To that end, the text features contributors who are major figures in molecular ecology and evolution – many having published books of their own. The aim is to direct and distill the thoughts of these outstanding scientists by compiling compelling case histories in molecular ecology as they apply to natural resource management. J. Andrew DeWoody is Professor of Genetics and University Faculty Scholar at Purdue University. He earned his MS in genetics at Texas A&M University and his PhD in zoology from Texas Tech University. His recent research in genetics, evolution, and ecology has been funded by organizations including the National Science Foundation, the U.S. Department of Agriculture (USDA) National Research Initiative, the Great Lakes Fishery Trust, and the National Geographic Society. His research is published in more than thirty-five journals, and he has served as Associate Editor for the North American Journal of Fisheries Management, the Journal of Wildlife Management,andGenetica.

Aculeate Bee and Wasp Survey Report 2015/16 for the Knepp Wildland Project
Aculeate bee and wasp survey report 2015/16 for the Knepp Wildland Project Thomas Wood and Dave Goulson School of Life Sciences, The University of Sussex, Falmer, BN1 9QG Methodology Aculeate bees and wasps were surveyed on the Knepp Castle Estate as part of their biodiversity monitoring programme during the 2015/2016 seasons. The southern block, comprising 473 hectares, was selected for the survey as it is the most extensively rewilded section of the estate. Nine areas were identified in the southern block and each one was surveyed by free searching for 20 minutes on each visit. Surveys were conducted on April 13th, June 3rd and June 30th in 2015 and May 20th, June 24th, July 20th, August 7th and August 12th in 2016. Survey results and species of note A total of 62 species of bee and 30 species of wasp were recorded during the survey. This total includes seven bee and four wasp species of national conservation importance (Table 1, Table 2). Rarity classifications come from Falk (1991) but have been modified by TW to take account of the major shifts in abundance that have occurred since the publication of this review. The important bee species were Andrena labiata, Ceratina cyanea, Lasioglossum puncticolle, Macropis europaea, Melitta leporina, Melitta tricincta and Sphecodes scabricollis. Both A. labiata and C. cyanea show no particular affinity for clay. Both forage from a wide variety of plants and are considered scarce nationally for historical reasons and for their restricted southern distribution. M. leporina and M. tricincta are both oligolectic bees, collecting pollen from one botanical family only. -
Salicornia and Other Annuals Colonising Mud and Sand
Salicornia and other annuals colonising mud and sand Site Description The Essex Estuaries European Marine Site lies on the East coast of Essex, in the South East of England. The European designation covers an area of approximately 472km2. It is made up of four estuaries; Colne, Blackwater, Crouch and Roach as well as open stretches of coast the Dengie, Foulness and the Maplin sands. The Essex Estuaries contributes to the essential range and variation of estuaries in the UK as the best example of a coastal plain estuary system on the British North Sea coast. Above high water the majority of the Essex Estuaries SAC is bounded by seawall defences, the majority of which have been constructed using clay excavated from the immediate area. This method creates an associated linear pond called a borrowdyke, ranging salinities and water temperatures in these borrowdykes supports a range of interesting associated species including Lagoon sea slug (Tenellia adspersa) [1] Essex Estuaries contains amongst others a designation for saltmarsh and its associated plant communities. Saltmarshes are areas of upper intertidal habitat vegetated with salt tolerant plants found on low energy coastlines where deposition levels are high. They are important habitats of high biological diversity, utilised by both marine and terrestrial species. They are documented as important nursery grounds at high tide supporting juvenile fish species including Bass and Grey mullet, Dab, Plaice & Sole all exploiting the warm shallow sheltered creeks which have a high nutrient value. At low tide waders including red shank (Tringa tetanus), Curlew (Numenius arquata) godwits (Limosa limosa) and (Limosa lapponica) utilise the exposed mud feeding on infaunal and epifaunal communities.The presence of seawalls and rising sea levels result is a process known as coastal squeeze. -
Translocation of Imperiled Species Under Changing Climates
Ann. N.Y. Acad. Sci. ISSN 0077-8923 ANNALS OF THE NEW YORK ACADEMY OF SCIENCES Issue: The Year in Ecology and Conservation Biology Translocation of imperiled species under changing climates Mark W. Schwartz1 and Tara G. Martin2 1John Muir Institute of the Environment, University of California, Davis, California. 2Climate Adaptation Flagship, CSIRO Ecosystem Sciences, Ecoscience Precinct, Queensland, Australia Address for correspondence: Mark W. Schwartz, Department of Environmental Science & Policy, 1 Shields Avenue, University of California, Davis, CA 95616. [email protected] Conservation translocation of species varies from restoring historic populations to managing the relocation of imperiled species to new locations. We review the literature in three areas—translocation, managed relocation, and conservation decision making—to inform conservation translocation under changing climates. First, climate change increases the potential for conflict over both the efficacy and the acceptability of conservation translocation. The emerging literature on managed relocation highlights this discourse. Second, conservation translocation works in concert with other strategies. The emerging literature in structured decision making provides a framework for prioritizing conservation actions—considering many possible alternatives that are evaluated based on expected benefit, risk, and social–political feasibility. Finally, the translocation literature has historically been primarily concerned with risks associated with the target species. In contrast, -
