If you visit the Grand Canyon this summer you might witness a majestic herd of bison roaming near the North Rim. While to the average tourist the bison might seem like a totally natural sight, conservationists don’t see it that way. As the National Park Conservation Association explained, “they argue that the bison don’t belong in the park, where the animals overgraze meadows, contaminate water sources and trample archaeological sites. Left alone, the herd of more than 600 — no one knows exactly how many — could more than double over the next decade.”
How Did the Bison Get There? It’s kind of a wild back story but as the NPCA explained,
In 1906, a frontiersman named Charles Jones assembled a herd of bison captured in places from Manitoba to Texas and attempted to breed them with Galloway cattle. This type of experimentation was common at the time, and these days, many bison contain some cattle DNA.
Jones struggled to build a profitable enterprise, though, and he gave up after a few years. He sold some of the animals, but about 20 were pretty much left to their own devices in House Rock Valley near the North Rim of the Grand Canyon.
By the time the state of Arizona purchased the herd in 1927, it had grown to 98 bison. To protect themselves from hunters the bison have since started avoiding House Rock Vally and now mostly live exclusively in the North Rim.
Bison Are Not Considerate Guests: The bison have ruined Native American artifacts, harmed native plant species, and have also spread E. coli in local streams and waterways. According to the National Park Service, water monitoring around the Grand Canyon has “indicated increased levels of E. coli bacteria in standing water associated with bison grazing areas. Large ungulate herds are known to cause significant damage to water sources through contamination and soil compaction.”
A Bison is a Bison is a Bison, Right? Well not exactly. Since the bison were bred with cattle long ago many consider them to be a non-native hybrid species, however, the Park Service has officially declared them to be native to the park. This can affect how the buffalo herds might be culled or corralled in the future.
Why This Matters: Addressing the bison problem at the Grand Canyon is difficult because the National Park Service has few resources to devote to the endeavor. Additionally, a change of park superintendent, chronic understaffing and a government shutdown over the winter have not helped. The NPS has stated that lethal culling will not take place in 2019 and plans to take it up in the future are not yet established. Other ideas include transporting the animals to their historic ranges, but again, understaffing and underfunding at NPS makes and proactive plan difficult to implement.
We know the permafrost in the Arctic is melting fast, but a new study finds that one of the reasons for its rapid decline may be that beavers are actually damming it up — literally. CNN reports that using satellite images scientists have observed that beavers are building dams way farther north than previously observed. […]
Throughout the coronavirus pandemic, animals have enjoyed the freedom of a quieter world by venturing further into cities and suburbs. While this “anthropause” has made for thrilling YouTube videos, scientists have taken the opportunity to study the effects of human activity across geographic regions, ecosystems, their effect on species. Researchers have been tracking animal movements […]
The Boston Globe’s David Abel reported on Twitter last week that the National Oceanic and Atmospheric Administration (NOAA) is, according to court filings, delaying new protections for critically endangered North Atlantic Right Whales even after a court found the agency in violation of the Endangered Species Act for its failure to take action to protect them.
Why This Matters: There are fewer than 400 North Atlantic Right Whales remaining.
