The pandemic offers scientists a dramatic opportunity to drive home the need for such commitments.
Though a tragedy, the pandemic is “this once in a lifetime event” to evaluate the effects of our behavior on nature, says Richard Primack, a biologist at Boston University, who is working with scientists globally
to compile research about Covid-19’s impact on conservation, for the journal Biological Conservation. “We going to see these
enormous changes in human activity.”
A major question, says Primack, is whether the ways in which humans try to protect nature actually work. “Maybe (the data) will tell us that the management we have is not important, if biological systems are really staying the same. Or maybe it’s telling us that the management is critical.”
One colleague of Primack’s sees early evidence to support scaling up protection.
David Philipp, an avid angler and conservation biologist at the Fisheries Conservation Foundation, has been studying bass populations in the lakes and rivers of southern Ontario for 30 years. For decades, he says, sport fishing caused a disastrous annual depletion of baby bass, by disrupting father fish as they guarded their nests from predators.
But between 2019 and 2020, the number of surviving baby bass in Philipp’s research zone more than tripled, from 124,000 to 414,000, a change that he attributes to a halt on fishing due to pandemic lockdowns and the US-Canada border closure. This year’s surviving fry could live as long as 15 years, theoretically rejuvenating the population for years.
His research, which is still under review, could be a decisive piece of Philipp’s pitch to the Canadian government for a pilot project that would effectively replicate lockdown’s benefits, by blocking off nesting areas in lakes from fishing for a few months each year.
Lockdowns have “given people a glimpse of how quickly things can improve if we take action,” Andersen says. Though sightings of flora and fauna thriving during mankind’s confinement may not tell the whole story, she hopes they will inspire the public to reconnect with nature and demand more environmental protections in the future.
Primack, the biologist, has wondered whether in some cases, the animals spotted during the pandemic had been visiting urban spaces all along. “People might have been just rushing around too much to notice them before,” he says. Only long-term studies will eventually show whether wildlife in some areas really did take advantage of the sudden quiet to explore, or whether we just began to see things differently.
