California officials encouraging residents to eat invasive rodents
Wildlife officials are encouraging California residents to add a rodent to their daily diet as part of efforts to control the invasive species' population.
The nutria, a large, semi-aquatic rodent native to South America, is threatening the state's ecosystems by destroying habitats and outcompeting native wildlife. The nutria's harmful impacts have prompted wildlife officials to promote hunting and consumption as possible solutions.
'Eating invasive species can help protect native wildlife by reducing their numbers and limiting the damage they cause to ecosystems,' reads a statement released in late February by Erin Huggins, a spokesperson for the Fish and Wildlife Service. 'However, it's not a complete solution and should be combined with other conservation efforts to effectively control these species.'
According to the California department of fish and wildlife (CDFW), nutria were originally introduced to the US for the fur trade but have since established themselves in as many as 18 states. The rodents can grow up to 40in (102cm), which is nearly as large as a beaver or a small dog.
They were believed to have been eradicated from California in the 1970s, but a spike was detected in 2017, especially in the Sacramento-San Joaquin River delta and surrounding wetlands.
Federal wildlife officials are trying to make the consumption of nutrias somewhat enticing by drawing similarities to the taste of rabbit or dark turkey meat. Resources, including recipes for nutria dishes such as stews and chili, are available on Nutria.com.
Nutria are highly destructive to marsh environments. The rodents eat up to a quarter of their body weight in vegetation daily. Their feeding habits not only destroy native plant life but also destabilize soil structures, which can result in heavy erosion and habitat loss for threatened and endangered species.
To mitigate their impact, CDFW has removed about 5,500 nutria from California wetlands as of early February. The highest concentration of these rodents were found in Merced, Fresno, Stanislaus and Solano counties.
The call to eat nutrias came during National Invasive Species Awareness Week in late February, a time dedicated to calling attention to the urgency of addressing the harm of invasive species before they cause further ecological and economic damage.

Cub found alone in US woods now being raised by wildlife staff in bear costumes
Human bears, some would say, are taking care of a two-month-old cub that spent days without his mother, starving in a California forest. The small black bear cub was rescued by campers in Los Padres national forest after being found alone and starving. The infant bear is now recovering at San Diego Humane Society's Ramona Wildlife Center, and is believed to be the youngest cub the organization has ever cared for. The two-month-old cub was discovered on 12 April by campers hiking in the forest. Wildlife officials with the California department of fish and wildlife (CDFW) attempted to reunite him with his mother overnight, but she didn't return. The cub was transferred to the Ramona facility two days later. 'The cub is thriving here. When he first arrived, he was only 3lbs and was a little debilitated, probably from going multiple days without any kind of nutrition or hydration,' said Autumn Welch, wildlife operations manager at the center. 'He's now quadrupled in size, he's over 12lbs.' Now thriving after more than a month of around-the-clock care, the cub is expected to remain at the center for up to a year. Staff are using enrichment sessions that mimic maternal behavior to prepare him for a future return to the wild, including staff members dressed as bears, plush toys and camouflaged headsets. Welch said that keeping bears away from human interaction when they are young is key to avoiding conflicts in the future, once they're released in the wild. 'They're really smart and very food motivated,' Welch said. 'As we continue to develop in the areas they live, they're always being pushed into areas where people may have some type of conflict with them. 'Sometimes bears will get into trashes or get into people's yards,' she added. 'The more we can keep this cub wild and keep him from recognizing humans as the providers of anything good, we're hoping every time we go in there, he's seeing us as other bears and being able to identify with us as bears instead of humans.' Officials say he could eventually be paired with another orphaned cub to help his development and minimize human imprinting. Welch said the CDFW determines the site of where any of the bear cubs and rehabs go after they are released into the wild. The department takes into consideration a number of factors, such as where the bear was found, what the population is like in that area, if there's any human wildlife conflict, and whether the site will provide for their nutrition needs. She estimates the recently found cub won't be released until the end of next spring or early summer.

'They're usually around 130 to 150lbs and they get fitted with the GPS collar because the government biologists track them and see where their movements are and what they're doing for a whole year after release.' CDFW said this is only the fourth bear cub this young to enter rehab care in California in the past five years. Raising such a young animal, Welch said, requires extensive time, expertise and funding – none of which comes from the state. The San Diego Humane Society relies solely on donations to sustain its wildlife rehabilitation efforts. The Ramona Wildlife Center is the only facility in San Diego county permitted to rehabilitate native apex predators, including black bears, mountain lions and bobcats. 'This is a very unusual case,' Welch said in a press release. 'We don't often see bears this young without their mother. It's an honor to care for him, but it's also a significant commitment.'

Adorable bear cub is flourishing after being found abandoned and malnourished
An abandoned bear cub who was found starving in a California forest is now thriving in his new shelter. The two-month-old male arrived to the shelter 'weak, underweight, and alone', according to the San Diego Humane Society. Campers in Los Padres National Forest discovered the orphaned black bear cub on April 12. California Department Of Fish And Wildlife (CDFW) biologists tried to reunite the baby with his mother by returning him to the wild overnight. However, she did not return for him, and with no signs of a mama bear in the area, the cub was transported to San Diego Humane Society's Ramona Wildlife Center on April 14. Autumn Welch, Wildlife Operations Manager at the center, said: 'He was extremely fragile when he arrived. 'This is a very unusual case. We don't often see bears this young without their mother.' The baby bear had health problems, and, combined with his young age, his caregivers were worried he might not make it. Welch said: 'After going several days without nutrition, it was touch-and-go at first. But now, he's active, eating well and gaining weight steadily.' The San Diego Humane Society said the bear receives four enrichment and feeding sessions daily, with overnight feedings required in his early days to help stabilize him. Daily care: The shelter said the bear receives four enrichment and feeding sessions each day Photos from the enrichment sessions show staff wearing wildlife costumes and mimicking maternal behaviors to prevent the cub from forming an emotional attachment to humans. Other snaps show the cub playing with toys, chewing on leaves, and drinking from a bottle. The San Diego Humane Society said it does not receive state funding and depends on community contributions to care for wild animals in need. Welch said: 'It's an honor to care for him, but it's also a significant commitment. We rely entirely on donations to make this kind of specialized care possible.' Male black bears can grow up to be 500lb and have powerful limbs and well-developed claws on large, strong paws. The caregivers expect him to remain with them for up to a year and hope to release the bear cub back into the wild one day.
