Preface

The federal, provincial, and territorial government signatories under the Accord for the Protection of Species at Risk (1996) agreed to establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada. Under Section 46 of the Species at Risk Act (S.C. 2002, c.29) (SARA), the competent ministers are responsible for reporting on the implementation of the recovery strategy for a species at risk, and on the progress towards meeting its objectives within five years of the date when the recovery strategy was placed on the Species at Risk Public Registry and in every subsequent five-year period, until its objectives have been achieved or the species’ recovery is no longer feasible.

Reporting on the progress of recovery strategy implementation requires reporting on the collective efforts of the competent minister(s), provincial and territorial governments and all other parties involved in conducting activities that contribute to the species’ recovery. Recovery strategies identify broad strategies and approaches that will provide the best chance of recovering species at risk. Some of the identified strategies and approaches are sequential to the progress or completion of others and not all may be undertaken or show significant progress during the timeframe of a Report on the Progress of Recovery Strategy Implementation (Progress Report).

The Minister of Fisheries and Oceans is the competent minister(s) under SARA for the Cultus Pygmy Sculpin (Cottus aleuticus, Cultus Population)1 and has prepared this Progress Report.

As stated in the preamble to SARA, success in the recovery of species at risk depends on the commitment and cooperation of many different constituencies that will be involved in implementing the directions set out in the recovery strategy and will not be achieved by Fisheries and Oceans Canada, or any other jurisdiction alone. The cost of conserving species at risk is shared amongst different constituencies. All Canadians are invited to join in supporting and implementing the Recovery Strategy for the Cultus Pygmy Sculpin for the benefit of the species and Canadian society as a whole.

Acknowledgments

This Progress Report was prepared by The Department of Fisheries and Oceans Canada. The Department of Fisheries and Oceans would also like to express its appreciation to all individuals and organizations who have contributed to the recovery of the Cultus Pygmy Sculpin.

Executive summary

The Cultus Pygmy Sculpin was assessed as Threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in 2000, and subsequently listed under the Species at Risk Act as such in June of 2003. In October of 2007 the final Recovery Strategy for Cultus Pygmy Sculpin (Cottus sp.) in Canada was posted to the Species at Risk Public Registry. An updated COSEWIC assessment in 2010 reconfirmed the species’ status as Threatened (COSEWIC 2010).

Threats to the Cultus Pygmy Sculpin, as identified in the Recovery Strategy for Cultus Pygmy Sculpin (Cottus sp.) in Canada (NRTCPS 2007), include: exotic species, altered predation rates, water use and quality, water-oriented recreation, land use, and climate change. The recovery goal for Cultus Pygmy Sculpin is to ensure the long-term viability of the population in the wild.2 This taxon is likely to remain at an elevated risk due to the population’s extremely limited distribution.     

This report documents the progress of Recovery Strategy implementation for the Cultus Pygmy Sculpin. It summarizes progress that Fisheries and Oceans Canada, the Province of British Columbia’s Ministry of Environment, and other interested parties have made towards achieving the goal and objectives set out in the Recovery Strategy, including:

  • conducting new research and monitoring activities (including advancing studies to support the identification of critical habitat); and,
  • completing management activities that help Canadians reduce impacts on, and better understand threats to, the Cultus Pygmy Sculpin..

1. Background

1.1 Species status

Assessment Summary – April 2010

Common name
Cultus Pygmy Sculpin – Cultus Population

Scientific name
Cottus aleuticus

Status
Threatened

Reason for designation
This species is a small Canadian endemic freshwater fish found in a single lake in the lower mainland region of southwestern British Columbia, an area undergoing sustained and rapid urbanization. The lake is heavily used by recreationists and drains into the lower Fraser River area where many invasive species are well-established. Trends in indices of abundance suggest a persistent decline and the single location makes the species particularly vulnerable should either habitat quality decline or vertebrate invasive species become established in the lake.

Occurrence
British Columbia

Status history:
Designated Special Concern in April 1997. Status re-examined and designated Threatened in November 2000 and in April 2010.

Species at Risk Actstatus:
Listed, Threatened

1.2 Threats

1.2.1 Threats to Morrison Creek lamprey

Threats to the Cultus Pygmy Sculpin (Cottus aleuticus, Cultus Population), as identified in Section 3 of the Recovery Strategy for Cultus Pygmy Sculpin (Cottus sp.) in Canada (NRTCPS 2007), include: exotic species, altered predation rates, water use and quality, water-oriented recreation, land use, and climate change.

1.2.2 Activities likely to destroy critical habitat

Neither critical habitat nor activities likely to destroy critical habitat were identified for the Cultus Pygmy Sculpin in the Recovery Strategy; however, these will both be identified in a forthcoming Action Plan.

2. Recovery

2.1 Recovery goal and objectives

The Recovery Goal and Objectives3(identified in Sections 7 and 8 of the Recovery Strategy respectively) are as follows:

Recovery Goal

Ensure the long-term viability of the population in the wild.4 This taxon is likely to remain at an elevated risk due to the population’s extremely limited distribution.

Recovery Objectives

  1. Foster awareness of Cultus Pygmy Sculpin and its conservation status. Encourage active local involvement in stewardship and habitat protection.
  2. Maintain, and where possible enhance, the ecological integrity of habitat for Cultus Pygmy Sculpin.
  3. Increase scientific understanding of Cultus Pygmy Sculpin through additional investigation of its natural history, critical habitat and threats to its persistence.

2.2 Performance measures

Performance Measures (as outlined in Section 9 of the Recovery Strategy) are reproduced in detail in Section 3.3 of this report.

3. Progress towards recovery

Section 46 of the Species at Risk Act requires the competent Minister to report on the implementation of the Recovery Strategy and the progress towards meeting its objectives, within five years after it is included in the Species at Risk Public Registry, and in every subsequent five-year period, until its objectives have been achieved or the species’ recovery is no longer feasible. In the interest of capturing the most recent progress on the recovery of the Cultus Pygmy Sculpin, this document includes actions completed up to 2015.

3.3 Summary of progress towards recovery

Action Planning

Fisheries and Oceans Canada, in cooperation with the Province of British Columbia’s Ministry of Environment, is developing an Action Plan for the Cultus Pygmy Sculpin as part of the Government of Canada’s ongoing commitment to the conservation of species at risk through the implementation of the Species at Risk Act.

Report on Performance Measures

Performance measures (as outlined in the Recovery Strategy) and their outcomes are addressed below.

  1. Has a RIG or working group been established? Is the RIG adequately supported with funding and technical expertise? Has an Action Plan been developed? Is the RIG achieving the goals outlined in the Recovery Strategy?

    Groups such as CLASS and the Cultus Lake Project perform the functions of RIGs. Funding is largely obtained on a year-to-year basis. Specifically, CLASS is supported via technical expertise, cash, and in-kind contributions by the following organizations: Fraser Basin Council, Fisheries and Oceans Canada, Fraser Valley Regional District, municipal government staff, BC Parks, Canadian Wildlife Federation, Pacific Salmon Foundation, Fraser River Salmon Table, BC Family Fishing, Vancity, Soowahlie First Nation, Ts'elxwéyeqw Tribe, Stó:lō Tribal Council, Stó:lō Nation members, Fraser Salmon Watershed Program, Lindell Beach ratepayers, Columbia Valley residents, Cultus Community Association, youth, school districts, teachers, artists, businesses, industry, various non-governmental organizations, and others.

    DFO developed a draft Action Plan for the Cultus Pygmy Sculpin in cooperation with the Province of British Columbia’s Ministry of Environment, as per section 48(1) of the Species at Risk Act. DFO conducted regional consultations on this draft in November and December 2012. A Proposed Action Plan for the Cultus Pygmy Sculpin is currently under development.

    The goal of the Recovery Strategy may never be fully achieved due to the Cultus Pygmy Sculpin’s extremely limited distribution. However, in the timeframe of this report many achievements (outlined in Tables 1 and 2) are contributing to the recovery of the species.

  2. Has taxonomic status of Cultus Pygmy Sculpin been clarified?

    Woodruff (2010) and Woodruff and Taylor (2013) published taxonomic research and a recommendation with respect to Designatable Unit status under COSEWIC.

  3. Are there key information gaps that inhibit conservation of Cultus Pygmy Sculpin? 

    Several information gaps have been addressed, particularly regarding: life history, taxonomic status, and habitat use (DFO unpub. data, Woodruff 2010, Woodruff and Taylor 2013); diet (DFO unpub. data); genetics (Woodruff 2010, Woodruff and Taylor 2013); predation (Robinson pers. comm. 2013); threat clarification (DFO 2012, Chiang et al. 2015, Fraser Basin Council 2013); and monitoring of Cultus Lake (e.g. nutrient mass balance, water quality, plankton sampling; M. Robinson pers. comm. 2013, DFO unpub. data). However, several additional items remain to be addressed, namely related to: population abundance and dynamics; basic biology; water quality; nutrient loading/eutrophication; and, potential interactions with Cultus Lake Sockeye Salmon recovery efforts.

  4. Have threats been clarified and assessed? Are threats being mitigated?

    All research and monitoring conducted (refer to Rows 1, 2, 3, 5, 6, 7, 8, and 9 of Table 1) improves the understanding of threats to the Cultus Pygmy Sculpin. For example recording locations of Cultus Pygmy Sculpin captures and changes in habitat over time may indicate when and where threats are the most prominent. Increased knowledge of genetics may inform the degree of the Cultus Pygmy Sculpin’s endemism and overall susceptibility to threats. And, specific studies on nutrient loading, predation, and invasive species have further added to the body of knowledge for this species. Threats are further clarified and expanded upon in a CSAS Science Advisory Report (DFO 2012) and Research Document (Chiang et al. 2015), as well as a forthcoming Action Plan which outlines measures for mitigation and protection.

  5. Has critical habitat been defined for Cultus Pygmy Sculpin?

    DFO published a CSAS Science Advisory Report titled Recommendations for Cultus Pygmy Sculpin critical habitat(DFO 2012) and aResearch Document titled Identification of critical habitat for Coastrange Sculpin (Cultus Population) (Cottus aleuticus) (Chiang et al. 2015). A forthcoming Action Plan for the Cultus Pygmy Sculpin will officially identify critical habitat.

  6. Have monitoring programs been implemented? How long has a monitoring program been in place? Is it effective? Is it a benign activity for the population? Is funding secure for the long term?

    Harvey and Brown (2013b) incorporated best monitoring approaches into a draft SARA multi-species compendium report, which will inform the development and implementation of a comprehensive monitoring plan; handling is minimized in this approach, and is expected to be benign to the population. Effectiveness of a monitoring program is pending full implementation and analysis of data. Funding is largely obtained on a year-to-year basis.

  7. Have key areas in the watershed (i.e., those that are disproportionately important for maintaining habitat) been identified? Has a watershed plan that recognizes these habitats as important been developed? Have key habitats been effectively protected?

    Woodruff’s Master’s Thesis (2010) documented and confirmed habitat usage patterns observed historically, assisting in the identification of key areas in the watershed. DFO also developed a CSAS Science Advisory Report titled Recommendations for Cultus Pygmy Sculpin critical habitat (DFO 2012) and aResearch Document titled Identification of critical habitat for Coastrange Sculpin (Cultus Population) (Cottus aleuticus) (Chiang et al. 2015). In addition, the Cultus Lake Park Board is collaborating with the Fraser Valley Regional District to develop the “PlanCultus Community and Park Plan”; the document takes management of the Cultus Lake watershed and its wildlife into consideration (PlanCultus 2014).

    Under SARA, critical habitat must be legally protected from destruction within 180 days of being identified in a recovery strategy or action plan. A forthcoming Action Plan for the Cultus Pygmy Sculpin will identify critical habitat. It is anticipated that the protection of the species’ critical habitat from destruction will be accomplished through a SARA Critical Habitat Order made under Subsections 58(4) and (5), which will invoke the prohibition in Subsection 58(1) against the destruction of the identified critical habitat.

  8. Have water quality and water use objectives been established and communicated to relevant regulators and stakeholders?

    A forthcoming Action Plan for the Cultus Pygmy Sculpin identifies the development and implementation of an integrated land and water use plan (including investigating and establishing appropriate water quality objectives) as an activity to be undertaken voluntarily by other agencies, organizations and individuals.

  9. Have educational materials been produced? Has public perception and awareness been affected? How many classes have received educational presentations?

    Many educational materials have been produced including: a scale model of the species, identification slates, photos, T-shirts, postal box postings, a Caring for Cultus Lake handbook, a Cultus Lake User Survey Report, Soowahlie First Nation art work, a summary report of activities conducted by CLASS from 2007 to 2012; and, a new CLASS website (refer to rows 12 and 13 of Table 2 for more details).

    With respect to public perception, CLASS developed a Cultus Lake User Survey Report (2011). This survey asked ~157 people to indicate their level of concern for the Cultus Pygmy Sculpin, among other species. Without a follow-up survey for comparison it remains difficult to assess whether public perception has been affected or not. Therefore, the 2011 report may serve as a baseline from which progress can be measured in the future.

    An estimated 11 school classes have received educational presentations (Robinson pers. comm. 2013; CLASS 2015).

  10. Have land management criteria been developed? Is land development meeting the criteria? Have BMPs[25] been developed and communicated? Is there compliance with BMPs?

    The FVRD’s Official Community Plan for Electoral Area “E” (now “H”) includes numerous policies on Development Permit Area requirements in the Cultus Lake South – Lindell Beach area for sewage treatment and riparian area assessments, as well as development policies for rezoning that address storm water management impacts to Cultus Lake (Smith pers. comm. 2015). In addition, a forthcoming Action Plan for the Cultus Pygmy Sculpin identifies the development and implementation of an integrated land and water use plan as an activity to be undertaken voluntarily by other agencies, organizations and individuals; development of land management criteria is inherent in this activity. Development of official BMPs is also identified in a forthcoming Action Plan as an activity to be undertaken voluntarily by other agencies, organizations and individuals. Compliance monitoring is pending the establishment of official BMPs.

  11. Have scientific investigation protocols been set and communicated? Have they been implemented?

    Harvey and Brown (2013a, 2013b) incorporated best collection and monitoring approaches into draft SARA multi-species compendium reports, which will inform the development and implementation of a comprehensive monitoring plan. Communication and implementation of protocols are pending publication. Applications for scientific study involving the Cultus Pygmy Sculpin undergo permitting considerations per section 73 of the Species at Risk Act.

1 In Schedule 1 of the Species at Risk Act this species is officially listed as “Coastrange Sculpin – Cultus Population.” In this document, the common name “Cultus Pygmy Sculpin” is used throughout, to maintain consistency with the Recovery Strategy (NRTCPS 2007).

2 The geographic extent of this recovery goal will be clarified in a forthcoming Action Plan for the Cultus Pygmy Sculpin.

3Referred to in the forthcoming Action Plan for the Cultus Pygmy Sculpin as “population and distribution objectives.”

4 The geographic extent of this recovery goal will be clarified in a forthcoming Action Plan for the Cultus Pygmy Sculpin.
