Livestock may be threatening endangered species in Arizona and New Mexico: Report
Uncontrolled livestock grazing is destroying streamside habitats that are critical to endangered plants and animals in Arizona and New Mexico, a new report has found.
Half of roughly 2,400 miles surveyed since 2017 showed significant harm to such spots, while 13 percent of the areas incurred moderate damage, according to the report released Wednesday by the Center for Biological Diversity.
Only 14 percent of the places surveyed demonstrated no damage at all, per the report.
'These animals and plants don't have a chance at survival if the streams they rely on are allowed to be devoured by hungry cows and made into stinking manure pits year after year,' Chris Bugbee, a Southwest conservation advocate for the Center for Biological Diversity, said in a statement.
The surveys included 178 U.S. Forest Service and 35 Bureau of Land Management grazing allotments in the two states, as well as critical habitats administered by both agencies outside of the allotments.
They found documented damaged from authorized, unauthorized and feral livestock grazing within federally designated critical spaces.
Related to these observations, the Center for Biological Diversity and its partners said they have supported lawsuits that have resulted in 3,657 livestock being removed from impacted habitats in both states.
'The good news is that creeks and riparian areas have begun to recover in the places where our litigation has kept cows out,' Bugbee said. 'Full recovery will take decades.'
The livestock, according to the report, destroy the habitats by defecating and urinating in the streams, trampling on the banks and ravaging vegetation.
This type of behavior also prevents new riverside forests from regrowing, the authors noted.
Some of the species affected by these circumstances include rare fish, certain types of garter snakes, the Jemez Mountains salamander and the Chiricahua leopard frog, according to the report.
Also impacted are the New Mexico meadow jumping mouse and jaguar, as well as several bird species: the Southwestern willow flycatcher, the Western yellow-billed cuckoo and the Mexican spotted owl.
The authors urged the federal government to take swift action to protect the riverside and aquatic critical habitat by removing more cattle from these sensitive areas.
Maintaining the status quo, they concluded, could risk 'driving to extinction those species that rely on riparian habitat there.'

AstraZeneca taps Chinese biotech in $5.2bn chronic disease research deal
AstraZeneca has joined the long list of big pharma companies enlisting the services of Chinese biotechs, signing a deal worth up to $5.2bn with CSPC Pharmaceuticals to research chronic disease drug candidates. Under the deal, AstraZeneca will pay an upfront fee of $110m, along with milestone payments of $1.62bn. CSPC are also in line to receive $3.6bn in sales milestone payments. AstraZeneca and CSPC will discover and develop pre-clinical candidates for multiple targets, which, according to the companies, will have the 'potential to treat diseases across chronic indications, including a pre-clinical small molecule oral therapy for immunological diseases'. CSPC will use its AI-powered drug discovery platform, which uses the technology to analyse the binding patterns of target proteins with existing compound molecules. The AI models work out targeted optimisation, advancing small molecules with the best developability. For any candidates identified via the research partnership, AstraZeneca will have the right to exercise options for exclusive licences to develop and commercialise candidates worldwide. AstraZeneca's executive vice president and biopharmaceuticals R&D head Sharon Barr said: 'This strategic research collaboration underscores our commitment to innovation to tackle chronic diseases, which impact over two billion people globally. 'Forming strong collaborations allows us to leverage our complementary scientific expertise to support the rapid discovery of high-quality novel therapeutic molecules to deliver the next-generation medicines.' The partnership marks the second time this year AstraZeneca has invested resources in China. In March 2025, the drugmaker revealed plans to infuse $2.5bn over the next five years in Beijing to establish an R&D hub. China is enjoying a fruitful alliance with Western big pharma companies, despite a frosty relationship with US President Trump's administration, mainly due to the BIOSECURE ACT, which is admittedly now in legislative limbo. Licensing deals between US and Chinese biopharma companies hit record highs last year, up 280% from 2020, according to analysis by GlobalData. Across big pharma, transactions rose 66% from $16.6bn in 2023 to $41.5bn in 2024, demonstrating that China is still the go-to place to discover pipeline candidates. For deals specific to US companies, the analysis found that total deal value rose from $15.7bn in 2023 to $21.3bn in 2024. GlobalData is the parent company of Pharmaceutical Technology.

County officials warn of possible fly infestation
Although no Texas cases had been reported as of Tuesday, Johnson County Commissioner Larry Woolley warned of a potential screwworm fly infestation in mid to late summer. In May, the U.S. Department of Agriculture suspended importations of cattle, horses and bison from Mexico into the U.S. to prevent New World screwworm movement north following detection in Veracruz, Mexico. 'A lot of people may not remember the last time one of these happened,' Woolley said during Monday's Johnson County Commissioners Court meeting. 'I was in high school. I remember it vividly. It's not a pretty site and it's not something to be taken lightly.' Commissioner Kenny Howell agreed. 'I remember that too,' Howell said. 'It was a huge problem.' Although the closest detection is still 700 miles away, the New World screwworm is of increasing concern across the southern U.S., as it can potentially cause losses in the livestock and wildlife-related industries if it moves across the Mexican border and reestablishes. The USDA Animal and Plant Health Inspection Service is working with Mexican officials to train personnel and expand surveillance and eradication efforts in Mexico to better address the movement of the fly northward. Should the New World screwworm enter the U.S., this fly is estimated to cause losses, conservatively, of $2.1 billion to cattle and $9 billion to the hunting/wildlife industry in Texas. Where the larvae of other flies feed on carcasses, the larvae of these flies feed on the live flesh of animals including people. 'All it takes is a cut or a drop of blood to attract them,' Woolley said. 'They are flesh-eating larvae called screwworms.' The larvae of the New World Screwworm flies burrow into the flesh of warm-blooded animals resulting in damage, possible secondary infections and potentially death, according to the Centers for Disease Control and Prevention. 'The control method then and now is the distribution of sterile male flies into the population, and that's something they're working on now,' Woolley said. Typical insecticide use on the New World screwworm is not as effective as with other insect pests due to its wide host range and occurrence on wildlife. Eradication is the best way to control screwworms. However, control/removal of the fly when found on hosts is critical to reducing the local population so that the sterile fly program succeeds more quickly and reduces animal suffering. The New World screwworm is incapable of overwintering in regions that experience low temperatures or extended dry periods — they don't do well below 45 degrees and certainly die if frozen, however, the larvae can burrow about 6 inches into the soil, changing the temperatures that they experience. This fly poses a serious threat to livestock and wildlife because it deposits eggs into the wounds of living animals, thereby leading to larval infestations. Because they can host on any living mammal, they can also affect pets and humans. This metallic green-blue fly with large orange eyes is about twice the size of a common house fly. New World screwworms do not bite animals; their damage comes from laying eggs in the open wounds of living, warm-blooded animals — though rarely birds. The immature fly larvae, or maggots, feed on the living tissues of hosts, burrowing into the animal's tissue, causing tremendous damage and often resulting in the host's death. Historically, ranchers have altered breeding dates to avoid birthing during the fly season. Common livestock management practices and events, such as castration, dehorning, branding and birthing in all animals and antler velvet shedding in deer, often resulted in infestations. Infestations can occur at the site of any recent wound, like a scrape, lesion or even a tick-feeding site. Other wounds of common infestation include those from ear tagging or shearing, as well as mucous membranes and antler shedding in deer. Newborn mammals are prone to infestations at the healing umbilical cord site. If a wound on a living animal is found to have larvae in it, a veterinarian must be contacted. Find an accredited veterinarian or Texas Animal Health Commission, TAHC, region office. The veterinarian is mandated by law to collect and submit the larvae for identification to the USDA's National Veterinary Services Laboratory. Also, the animal should be immediately confined for wound care, and all larvae should be removed and placed into alcohol. After removing the larvae, treat the infestation with topical pesticides labeled for use on the animal to kill any larvae that may not have been removed and reduce the likelihood of re-infestation. The wound should be monitored until it fully heals. When dealing with livestock, all other animals in the herd should be checked for wounds and larvae. Anyone who finds fly larvae infesting a living animal, called myiasis, must report this to a state veterinarian. The protocol for reporting can be found on the Texas Animal Health Commission website or at the USDA-APHIS website. An informational webinar on the topic is available at and as a link through the county's website. 'I encourage people to watch that to be educated on the possible problems this may pose,' Woolley said. 'It can affect livestock, pets, people.'

BC's sunflower sea stars are now endangered, but rays of hope remain
Sunflower sea stars clinging to life in BC's cold-water fjords are officially on the edge of extinction, a scientific advisory panel is warning. A once-abundant predator of the sea floor along the Pacific coast, stretching from Alaska to Baja California, Pycnopodia helianthoides, has been assessed as endangered by the federal Committee on the Status of Endangered Wildlife in Canada (COSEWIC). While disheartening, the decision isn't unexpected and could offer a margin of hope for the survival of the massive, vibrant sea star, said Alyssa Gehman, marine ecologist with the Hakai Institute. The only type of its genus, an adult sunflower star Pycnopodia (which comes in a variety of purple, orange or pinks) is one of the largest, fastest sea stars in the ocean, often reaching a metre wide with 16 to 24 arms. It has 15,000 tube feet that suspend it off the seafloor and allow it to move more than a metre per minute when on the prowl for prey, Gehman said. 'They kind of look like a hovercraft moving towards their food.' The species has suffered catastrophic population declines of 80 to 90 per cent in the last decade due to a marine epidemic known as sea star wasting disease that causes white lesions on the many-armed creatures before rapidly reducing them to mush. The wasting syndrome surfaced in 2013 along with spiking ocean temperatures caused by climate change, Gehman said. The disease attacks other types of sea stars as well, but it's decimated the sunflower variety, pushing them into virtual extinction in California and Mexican waters. Pockets of sunflower sea stars have found some refuge from the disease tucked away in the deep, cold inlets of the BC central coast, Gehman said. However, those remaining populations aren't immune to outbreaks and their chances of survival remain fragile. 'While [being endangered] is clearly bad news, the silver lining is that COSEWIC's acknowledgment might finally generate momentum to save Pycnopodia — whether that's in the form of funding, policy changes, or conservation programs,' Gehman said. The federal ministry of the environment and climate change will examine the committee's report in the fall to consider protecting the sunflower sea star under Canada's Species at Risk Act (SARA). It's illegal to kill, harm or capture wildlife listed under the act. Identifying critical habitat and devising a recovery strategy, complete with timelines and outcomes, is also required for a protected species. 'I hope it's a speedy process because there's real urgency,' Gehman said. 'From a conservation perspective, even though we have these really amazing refuge populations that give us a lot of hope, they're not stable … So, the more we can learn about what is happening with them, the more that can help us to try and conserve the species.' The sunflower sea stars are carnivores that play an important role in ocean health, said Gehman. Their primary prey is sea urchins which, if left unchecked by predators, can mow down kelp forests that offer food and shelter for lots of different marine life. Gehman and other researchers are monitoring between six and 12 fjords to pinpoint the conditions that offer sunflower sea stars the most protection against the disease. Water chilled and churned up by Arctic winter winds channelled into the inlets seems to buffer the impacts, she said. In warmer weather, glacial melt creates a freshwater surface layer in the fjords. Since Pycnopodia don't like fresh water, the sea stars move deeper into saltier, colder water layers, which appears to slow but not completely prevent outbreaks, Gehman said. Typically, sunflower stars in other areas of the coast prefer water temperatures around 16 C. But now it appears that water temperatures must be less than 12 C to limit the spread of the pathogen. 'The disease is actually changing what temperature would be best for them,' Gehman said. The sea stars haven't adapted quickly enough to the disease to consistently avoid warmer waters, which makes understanding the factors at play in their cold-water hideouts critical for their survival, she said. Research is taking place south of the border to breed sunflower sea stars that are more resistant to the wasting disease, so they can potentially be released into the wild to repopulate marine areas. In future, Gehman wants to study other kinds of sea stars — like the purple or orange ochre sea stars on the West Coast— that have better withstood the withering disease in a bid for clues scientists could use to help out their much larger cousins. Identifying and protecting coastal fjords that offer the best conditions for sunflower sea stars is also an important step. Although the Pycnopodia situation is grave, Gehman says she recently experienced a rare and magical moment when the research team witnessed a massive spawning event involving 20 to 30 sea stars, while surveying one of the fjords. 'It's absolutely wild,' Gehman said, The sunflower sea stars have pores that circle the centre of their body. The marine creatures stretch upward on extended arms and arch their bodies, with females releasing masses of pinkish eggs while males emit white clouds of sperm. 'Only the tips of their arms are on the bottom with their middle body tented up into the water column,' she said. 'There were some absolutely giant animals. It kind of looks like there's a halo of pores on them, and everything is pouring out into the water — it's really surreal.' The spawning event is a hopeful sign these cold-water strongholds can offer the endangered species some measure of resiliency from climate change and disease, she said. But the situation remains tenuous and variable, said Gehman, noting on the same trip researchers found sunflower sea stars had been wiped out in one inlet but had bounced back in another. 'So, scientifically, we're learning a lot while also being sad,' she said. Rochelle Baker/Local Journalism Initiative/Canada's National Observer Error!
