Within the surge of news coverage for the COVID-19 pandemic, you may have
heard about the increase in the reporting of wildlife sightings in some urban
areas across the globe, such as in this CBC
article. With less people venturing outside of their homes in efforts to prevent
the spread of the coronavirus, the media in multiple countries around the globe
have been reporting more sightings of wildlife that are usually rarely or
uncommonly seen in suburban and urban areas.6,7 This was the case
when a herd of Kashmir goats were seen strolling through the deserted streets
of a town in Wales during the lockdown.7

This also
happened in Toronto, Canada this past summer, where foxes were seen denning in
typically busy areas of the city during lockdown.2 To read more
about the Tale of Toronto’s boardwalk
foxes, check out this article in Maclean’s magazine. What does this unusual and greater number of wildlife
sightings in urbanized areas mean for wildlife behaviour and
wildlife conservation as a whole?

The “rolling
lockdowns” implemented as strategies to contain the novel coronavirus have
severely restricted human activities, and have had cascading effects through
public health systems and economies.6 What is less clear however, is
what impacts this sudden change in human behaviour may have on wildlife and
what the long-term implications are for the fate of wildlife conservation
across the globe and into the future. The interaction between our societal
response to COVID-19 and wildlife is a novel and emerging topic that scientists
have only just begun to investigate. Unsurprisingly, initial findings tell a
complex story, where lockdowns have had both positive and negative impacts on wildlife
and the conservation of biodiversity.1,5,6
Initial
positive effects of lockdowns on the environment, in general, include reductions in industrial activities and manufacturing, and restrictions on the transport of
natural resources, leading to a decrease in global emissions and an increase in
air and water quality.1,5 Other studies report decreases in noise
pollution leading to an increase in sightings of animals in cities and harbours,
along with reduced numbers of animals being killed by ships in waterways and by vehicles
on roads.1,6 Similarly, a study conducted in Italy, the first
country to implement a lockdown, found a greater proportion of sightings of
species such as the crested porcupine in suburban and urban areas in 2020
compared to previous years.6 The same study also found
evidence for an increase in the abundance and breeding success of certain
species of birds during lockdown in urban areas, likely due to general decrease
in the presence of humans.6
A crucial
point to consider about all of these positive observed effects is that many of
these effects, such as the presence of uncommon animals in urban areas, are likely
to only be temporary and prone to reversal once restrictions are lifted and
humans begin to revert back to pre-lockdown behaviours.5,6 It is also
worth noting that many observed increases in animal numbers under lockdown
conditions could have resulted from an increase in observation effort with more
people participating in hobbies such as birding due to restrictions on other
activities during lockdowns.6 Similarly, the greater detection of
bird species could have been attributed to an increase in detection rates because
of a reduction of background traffic noise with less traffic volume in lockdown
conditions.6
There is
great concern that the COVID-19 pandemic will severely hinder efforts to conserve
biodiversity in the present as well as in the long term.6 During
lockdown, there have been substantial delays in both species at risk management
efforts and invasive species control programs,6 reduced funding
available for conservation because of overstressed economies, reductions in wildlife-based
tourism due to travel restrictions, and governmental capacity generally being
prioritized for COVID-19 relief measures.1,5 The pandemic has
undoubtedly put a strain on our capacity for conservation, and many initiatives
will be playing catch-up to make up for precious lost time, where many
of these conservation efforts are focused on species that are already teetering
on the brink.
Increased
human threats to nature are also expected to occur as a result of the lockdowns.5,6
As more people, especially in rural areas, are forced to navigate pandemic-driven
economic downturns, they may have no choice but to turn to protected areas for
resources.5 In addition to this, the reduced funding available for hiring
patrol staff such as park rangers in protected areas can result in a lower
likelihood of detecting poachers and can lead to an increase in illegal killing
of wildlife, which has been the pattern already observed in multiple places across the globe including Europe, Africa, and Asia.1,5,6

The surge of research
examining the interaction between societal response to COVID-19 and wildlife
tells a complex story.6 Although there were some positive effects of
the lockdown observed on wildlife, these will likely only be temporary until
restrictions are lifted, but the potential negative impacts could have
long-lasting effects on the conservation of biodiversity.5,6 Furthermore,
activities focused on the conservation of species and habitats can also help to
reduce the risk of future pandemics as the restrictions
put in place to protect certain species and their habitats can help to reduce our
exposure to species that are a high risk for virus transfer to humans, leading
to a lower risk of future outbreaks and subsequent pandemics.5
Overall, although
the COVID-19 lockdowns have shown some initial positive impacts on the
environment and wildlife, there are significant risks associated with these
lockdowns that may negatively impact the effectiveness of wildlife
conservation. In order to effectively prevent the accelerated loss of
biodiversity that could result from lockdowns, countries must ensure funding for conservation actions is not
neglected.
