Lake Huron Lake Ontario Lake Erie Species Basics 4Require cool, clear flowing water with riffle-pool sequences and overhanging streamside vegetation. 4Populations have been lost from several tributaries to western Lake Ontario and the length Adult male of stream occupied by several of the remaining populations has been reduced. 4 Urban development is thought to be the most significant threat acting upon populations in Ontario. Adult female Species Status 4COSSARO assessed as Threatened in 2000, based on observed declines and threats to remaining populations 4Species was uplisted to Endangered in 2009 under Ontario’s Endangered Species Act, 2007 4Committee on the Status of Endangered Wildlife In Canada (COSEWIC) upgraded from Special Concern to Endangered in 2007 4The Redside Dace is currently being considered for listing as Endangered under the federal Species at Risk Act (SARA). Endangered Species Act 4Both the species and its habitat are now protected under ESA as of February 2009 4Section (9) Prohibits killing, harming, harassing, capturing, possessing, transporting, collecting, buying, selling, trading, leasing or transporting species that are listed as threatened, endangered or extirpated 4Section (10) Prohibits damaging or destroying habitat of endangered or threatened species Endangered Species Act The ESA defines habitat as: Section 2(1)a: the area prescribed by regulation as the habitat of the species (Regulated Habitat), or Section 2(1)b: an area on which the species depends, directly or indirectly, to carry on its life processes, including life processes such as reproduction, rearing, hibernation, migration or feeding (General Habitat) As of February 2009, Redside Dace received protection under the General Habitat provisions of ESA The ESA requires that a proposal for a Habitat Regulation for Redside Dace be published by February 18, 2011 Recovery Strategy 4Recovery Team, initiated in 1999, has led development of the strategy 4Strategy first posted on the Environmental Bills of Rights Registry in 2005 for public comment 4 Strategy format revised this fall to be ESA compliant 4 Strategy now includes recommendations for future habitat regulation 4 Strategy to be posted on EBR for comment in December 2009 4 Final Strategy to be published by February 18, 2010 4 Government response statement which indicates the actions the Government intends to take in relation to the strategy is required within 9 months Habitat Mapping 4MNR is responsible for determining and mapping the habitat of the species 4The species is currently managed by the identification of current occupied aquatic resource areas (ARAs) 4 Current occupied reaches are those that have Redside Dace present within the past 20 years 4ARAs are a data layer in MNR’s Natural Resource Values Information System 4ARAs are based on delineation of reaches of stream that are connected, similar fish community, thermal structure or stream size 4ARAs are typically separated by instream barriers to fish movement or a change in stream order. 4 Both current occupied and historically occupied reaches are being mapped Habitat Mapping 4Example – Credit River map Habitat Mapping 4Example – Credit River map Management of Species Related Activities 4The management of the collection activities involving Redside Dace is important to the conservation of the species 4MNR is responsible for licencing commercial harvest of baitfish or scientific collections of fish 4 In most watersheds, MNR knows where current high density populations exist and the range of occurrence within a watershed 4 Consultations with the baitfish harvest industry began in 2009. 4 Approaches to species conservation are being developed with this industry Management of Species Related Activities 4MNR reviews fish collection proposals to ensure Redside Dace populations are protected and the proposed activities are consistent with protection or recovery interests 4Limit activities in known high population areas such that permitted activities complement the monitoring program for the species 4 prohibit activities that do not assist in the protection or recovery of the species 4 regional monitoring programs are consolidated into the species monitoring program 4 17 (b) permits required for protection and recovery related activities Management of Habitat Related Activities 4Since February 2009, MNR has been engaged in a large variety of development related project proposals involving potential impacts to Redside Dace habitat 4In some cases, ESA permits are required for proposals where impact to habitat cannot be avoided 4Demonstrating Overall Benefit is a requirement of 17(c) permits. 4Referrals come from Conservation Authorities and project proponents 4Projects are screened with knowledge of current occupied ARAs 4Proponents are advised to consult with MNR directly to determine potential for impact, possible impact mitigation solutions or design modifications Management of Habitat Related Activities 4Aurora District has been engaged in over 100 project proposals since February 4 SAR Biologist coordinates tracking and processing of proposals 4Management biologists consult with proponents and local Conservation Authority in determining course of action

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

  • Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa
    Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa By Jun Cheng A thesis submitted in conformity with the requirements for the degree of Masters of Science Ecology and Evolutionary Biology University of Toronto © Copyright Jun Cheng 2013 Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa Jun Cheng Masters of Science Ecology and Evolutionary Biology University of Toronto 2013 Abstract Area of Occupancy (AO) is a frequently used indicator to assess and inform designation of conservation status to wildlife species by the International Union for Conservation of Nature (IUCN). The applicability of the current grid-based AO measurement on freshwater organisms has been questioned due to the restricted dimensionality of freshwater habitats. I investigated the extent to which AO influenced conservation status for freshwater taxa at a national level in Canada. I then used distribution data of 20 imperiled freshwater fish species of southwestern Ontario to (1) demonstrate biases produced by grid-based AO and (2) develop a biologically relevant AO index. My results showed grid-based AOs were sensitive to spatial scale, grid cell positioning, and number of records, and were subject to inconsistent decision making. Use of the biologically relevant AO changed conservation status for four freshwater fish species and may have important implications on the subsequent conservation practices. ii Acknowledgments I would like to thank many people who have supported and helped me with the production of this Master’s thesis. First is to my supervisor, Dr. Donald Jackson, who was the person that inspired me to study aquatic ecology and conservation biology in the first place, despite my background in environmental toxicology.

  • The Ohio Journal of Science — Index 1951-1970
    THE OHIO JOURNAL OF SCIENCE — INDEX 1951-1970 JANE L. FORSYTH AND CHRISTINE M. GORTA Department of Geology, Bowling Green State University, Bowling Green, Ohio 43403 INTRODUCTION It is almost 20 years since the first General Index to The Ohio Journal of Science, which covered the issues from the beginning (1900) through 1950, was published (Miller, E. M., 1953, published by The Ohio State University and The Ohio Academy of Science). It is time, therefore, for another general index, dealing with issues appearing since 1950. This is that index. Unlike the first index, there is no separate listing of full references by author; rather, this is simply a combining of all the entries from all the yearly indexes from 1951 through 1972. Basically these original entries remain unchanged here, though mistakes found in a few were corrected, and some have been slightly reworded in order to fit better into this multiple listing. Entries relating to book reviews occur only for the years of 1963 through 1970, because book reviews were not included in the earlier indexes. It should also be noted that, though a few of these books represent merely a reprinting of older, out-of-date books, these books are not so identified in the entries in this index. Preparation of this index has been mostly handled by Miss Christine M. Gorta, under the direction of Dr. Jane L. Forsyth, Editor of The Ohio Journal of Science from 1964 to 1973, but others have also contributed to this work—mainly Misses Lauran Boyles and Laura Witkowski—contributers whose efforts are gratefully acknowledged.
