We recently addressed how Newfoundland’s species at risk legislation
compares to other provinces. In today’s
blog, we will address how Newfoundland’s Endangered Species Act (ESA) compares
to Canada’s Species at Risk Act (SARA) and the United States Endangered Species
Act (US ESA). By moving to the national
level, it is possible to address how countries are doing in terms of endangered
species legislation.
The Species at Risk Act (SARA) was passed in 2002. The sole purpose of SARA is to “prevent
Canadian indigenous species, subspecies, and distinct populations of wildlife
from becoming extirpated or extinct” and to “provide recovery of endangered or
threatened species” (SARA, 2002). Under
SARA, a body of wildlife experts forms the Committee on the Status of
Endangered Wildlife in Canada (COSEWIC), which is assigned to assess the status
of species across the country, and recommend species at risk to be listed under
SARA (Findlay et al., 2009). COSEWIC
forwards their recommendations to the federal Governor in Council (see Figure
1; Findlay et al., 2009). This is
similar to Newfoundland’s Species Status Advisory Committee (SSAC), which
forwards their recommendations to the Minister of Environment.
Figure 1. The species listing
process under SARA from the initial assessment by COSEWIC to its final listing
under SARA (Environment Canada, 2010).
As well, like Newfoundland’s ESA, there are issues with SARA. Candidate species are prioritized under
COSEWIC based on a combination of threats, population dynamics, et c., but if a species is listed as “Data Deficient”
SARA will not conduct more research on the species or reassess the species
immediately (Mooers et al., 2010). As
such, species that may be at risk of extinction, but are listed as “Data
Deficient” will not be protected under SARA.
Further, there are large discrepancies between the number of species
listed and there effective recovery strategies, recovery plans, and determined
critical habitats (see Figure 2).
Figure 2. The number of legally listed wildlife species up to 2003 and
the respective number of recovery strategies, recovery action plans, and
defined critical habitats. The black
bars indicate species that are listed as “Threatened” and white bars indicate
species that are “Endangered” (from Figure 3 of Mooers et al., 2010)
There are also large discrepancies between taxa (group of organisms), with
terrestrial mammals having proportionally less species assessed under COSEWIC
being listed under SARA’s legislation (see Figure 3; Findlay et al., 2009). Findlay et al. (2009) also report that
harvested species and northern species (from the territories) are substantially
less likely to be listed under SARA.
Figure 3. The proportion of taxa with completed assessments by COSEWIC
that are listed under SARA. The bars are
calculated differently to correct for differences in Not Listing a species,
where NL=outright rejection; NL(REF)=outright rejection or referred back to
COSEWIC; and NL(REF,EP)=outright rejected or referred back to COSEWIC or
deferred to an extended consultation period.
What is to be noticed is the trend, where marine fishes are not
represented at all, and birds, herps (reptiles and amphibians), plants, and
invertebrates are nearly always designated under SARA (from Figure 1 of Findlay
et al., 2009).
Comparing to Newfoundland’s ESA, SARA needs to work
harder to represent all of Canada’s biodiversity. Newfoundland’s ESA is not perfect either, as
many species that have been recommended for listing still have not been
assessed by the Minister (as discussed in our previous blog).
As we can see, there are problems that arise with
Canadian endangered species legislation.
But how does Newfoundland, and Canada, compare internationally? Particularly, how do we compare to the United
States?
The United States Endangered Species Act (US ESA) was
created in 1973 (nearly three decades before SARA) to protect threatened
wildlife (Gordon et al., 1997). A
species status under the US ESA is determined by the Fish and Wildlife Service
(FWS) for terrestrial and freshwater organisms, which designates a species as
either Endangered or Threatened (ESA, 1973).
The FWS is supposed to work with States, Tribes, private landowners, and
other federal agencies to carry out conservation actions as listed under the US
ESA (FWS, 2011). However, how well the
US ESA actually works is a different story.
The US ESA has become controversial, causing political
divisions and proposals to alter the legislation (Gordon et al., 1997). This is partly due to the US ESA being
applicable to private lands (not the case for SARA or NLs ESA) and conflicts
with economic activities (Gordon et al., 1997).
This has led to the US ESA being essentially non-effective, and
government spending has been placed elsewhere (see Figure 4; Gordon et al.,
1997). However, acting as a compromise
for the US ESA, Habitat Conservation Plans (HCPs) have been used to conserve
ecosystems that organisms rely upon (FWS, 2011). As such, the American government has focused
on protecting critical habitats for its biodiversity, which bypasses their own
legislation for protecting individual organisms at threat of extinction.
Figure 4. Government spending on its Fish and Wildlife Service (FWS) and
National Marine Fisheries Service (NMFS) compared to the all other Government
expenditures from 1989 to 1993 revealing the transition from heavy investment
in wildlife protection to much reduced investment efforts (from Figure 10 of
Gordon et al., 1997).
As we can see, there are several differences between
Newfoundland, Canadian, and American species at risk legislation. While Newfoundland and Canadian species at
risk legislation works in a similar manner of having an advisory committee and
a governing official doing the final listing, the United States has reduced its
use of it ESA, opting to use Habitat Conservation Plans instead. Where there are limitations in the US ESA,
Canada tried to make alterations (e.g., SARA not applicable on private land) to
better protect species at risk of extinction.
However, even with modifications to the legislation, there are still
problems that need to be overcome.
In our next blog, we will address how Newfoundland’s ESA
compares to legislation across the globe.
Our international focus will help to determine where the province, and
Canada, stands in terms of protecting its biodiversity through endangered
species legislation.

As species that are listed as "data deficient" looked into in the future or simply ignored unless something substantial comes up?
ReplyDeleteBrittany and Garry
Often species listed as "data deficient" are sidelined after the initial evaluation. As such, species that may be threatened could be missed and not listed under SARA if information is not readily available. However, data deficient species are supposed to be re-evaluated, but under SARA this is usually long overdue for these species, causing concern if these species are at the brink of extinction.
DeleteIn the graph of the taxon listed why is it that marine fish are ignored completely it seems, do they state why?
ReplyDeleteIan and Carissa
Many marine fishes that may be considered "threatened" are typically not listed due to being highly harvested and of economic value. Further, the DFO is supposed to recommend species to be listed under SARA, however this is not always the case. It brings into questions whether the evaluation of species (particularly economic species) is based off of scientific input and research, or whether the government and economic stakeholders have more sway in the listing of species under SARA. The Findlay et al. (2009) above provides a nice oversight on the limitations of species listing under SARA.
