FULFILLING SARA’S
PURPOSES: A SCIENTIFIC
PERSPECTIVE ON RECOVERY
AND MANAGEMENT OF
SPECIES AT RISK
Justina C. Ray, Ph.D.
![Page 2: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/2.jpg)
Purposes of SARA (2002)
Prevent Canadian indigenous species, subspecies,
and distinct populations from becoming extirpated
or extinct,
Provide for the recovery of endangered or
threatened species, and
Encourage the management of other species to
prevent them from becoming at risk.
![Page 3: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/3.jpg)
Obligations under SARA:
Engage in Recovery Planning
Prepare a Recovery Strategy and Action Plan for every species listed as Threatened or Endangered
Within the Recovery Strategy:
A Recovery Goal sets the strategic course for recovery planning by defining what „recovery‟ means
Population and Distribution Objectives establish the number of individuals and/or populations and the geographic distribution of the species required to successfully reach the recovery goal.

SARA does not define Recovery
Recovery Planners must rely on:
Ordinary meaning of the word
Interpretations of the legislation provide guidance
as to intent
Scientific understanding of what is required to
secure the long-term conservation of species
![Page 6: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/6.jpg)
“Recovery” must provide
a Scientific Baseline
![Page 7: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/7.jpg)
Ordinary Meaning of “Recovery”
Dictionary: regaining something lost, or returning or
restoring something to a normal (pre‐harm)
condition
does not mean either getting any worse than the
current state or staying the same
The state of having returned to a
normal (pre‐harm) condition
![Page 8: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/8.jpg)
SARA’s Purposes and Structure
Provide Insight:
SARA’s purposes: Recovery is a state distinct
from survival;
SARA’s preamble: recovery means more than
just keeping the species present in Canada;
and
SARA’s structure: Recovery is defined for each
listed species based on scientific and technical,
but not socioeconomic, considerations.

Conservation Biology
Founded in the mid-
1980s as a “crisis
discipline”
emphasizing the
categorization and
quantification of
extinction risk

Species with Secure Conservation
Status (Recovered) has:
Multiple populations across the species‟ natural range,
In representative ecological settings,
With replicate populations in each setting that are:
Self‐sustaining,
Genetically robust,
Ecologically functional, and
Resilient to climate and other changes

Ecological Functionality

Redundancy, Representation, and
Resilience
Redundancy multiple, geographically dispersed
populations and habitats across a species range
Representation retention of genetic,
morphological, physiological, behavioral, habitat,
or ecological diversity of the species so its adaptive
capabilities are conserved.
Resiliency the ability of the species to recover
from periodic disturbance
![Page 18: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/18.jpg)
How much Recovery is Enough?
Must be sufficiently precautionary to safeguard against
most future threats (and therefore risks) to the species‟
long‐term persistence as a part of biological diversity
![Page 19: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/19.jpg)
Our Scientific Knowledge often
Precludes Setting Targets
![Page 20: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/20.jpg)
Common Reasons to Lower the Bar
for Recovery Goals/Objectives
Confusing stages of recovery with separate
objectives
Confusing biological/technical feasibility with lack
of investment, will, or “social carrying capacity”
Confusing criteria for recovery with measures for
extinction risk
![Page 21: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/21.jpg)
1. Stages of Recovery
States or stages of Recovery ≠ a Range of Objectives
Redford et al. 2011
![Page 22: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/22.jpg)
2. Biological and Technical Feasibility
Informs the plausible limits to recovery for a species
SARA makes clear that this determination of feasibility does not include consideration of socioeconomics
Draft guidance: 1) reproduction capability, 2) habitat availability or restoration potential, 3) whether threats can be avoided or mitigated, and 4) whether demonstrably effective recovery techniques exist.

Biological and Technical Feasibility

Gray wolf
Historical
At “recovery”
Bergstrom et al. 2009
![Page 26: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/26.jpg)
3. Recovery ≠ De-listing
IUCN Red List categories are intended to guide
the classification of species into threat
categories that reflect the likelihood of a
species going extinct under prevailing
circumstances (Mace et al. 2008).
Identify species that are relatively close to the
endpoint on a downward trajectory
![Page 27: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/27.jpg)
Consequences of Equating De-listing
with Recovery
Policy decisions would begin at a threshold from
which very little can be traded off before long-term
persistence is in doubt;
Preclude the design of Recovery Strategies that get a
species well away from at‐risk status;
Species bouncing on and off the SARA list
Loss of transparent distinction between science and
policy considerations
![Page 28: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/28.jpg)

Purposes of SARA (2002)
Prevent Canadian indigenous species, subspecies,
and distinct populations from becoming extirpated
or extinct,
Provide for the recovery of endangered or
threatened species, and
Encourage the management of other species to
prevent them from becoming at risk.
![Page 32: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/32.jpg)
Special Concern Species
Preventing species from becoming at risk of
extinction is one distinct purpose of the Act
SC species are those that may become a
threatened or endangered because of a
combination of biological characteristics and
identified threats
Management plan must include “measures for the
conservation of the species that the competent
minister considers appropriate”
![Page 33: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/33.jpg)
“Manage” under SARA is also
undefined
Dictionary: to bring
about or succeed at
accomplishing
To resolve a disorderly
situation into an
intentionally orderly
situation.

Take-home Messages
Defining recovery under SARA is a scientific process set within a complicated legal and policy context;
To be scientifically defensible, and precautionary, recovery for must be defined as the maximum degree of restoration of the pre-harm state that is scientifically and technically feasible; and
Recovery must maximize the species‟ capacity to contribute to biodiversity and ecological functionality, its resilience to environmental change, and thus its likelihood of long term persistence.
![Page 37: Justina ray fullfilling sar as purpose](https://reader033.fdocuments.net/reader033/viewer/2022052820/54c5d3a94a79599b3c8b45c2/html5/thumbnails/37.jpg)
Take-home Messages
There are many pressures that lead to lowering the bar in defining recovery;
Allowing for this under the banner of socioeconomic pragmatism can and does promote continued incremental loss of populations and distribution, increases extinction risk, and is usually scientifically arbitrary; and
Preventing species from becoming “at risk” is a distinct purpose of the Act but is in practice an afterthought
