Spring is here and so is the sensitive timing periods for a variety of wildlife. In BC, most native birds and their nests are protected under the provincial Wildlife Act and federal Migratory Birds Convention Act – some all year round, and most only when active and occupied by a bird or its egg. In the Lower Mainland, the nesting period is generally between March 1 and August 31; however, for some birds, such as the Bald Eagle, Osprey, Great Blue Heron, and Pileated Woodpecker nests are protected year-round. Bird nest surveys can be an effective tool to reduce the risk of harming actively nesting birds if vegetation clearing for your project is required during the bird nesting window. Our professional biologists and Qualified Environmental Professionals (QEPs) can help identify active nests before vegetation is cleared.

You've probably heard that #SCOTUS did away with "Chevron deference" last week. We cover that for you today on WorkersCompensation.com. In a nutshell, the Court's majority, in an opinion written by Chief Justice Roberts, said: ???? The Aministrative Procedure Act requires courts to exercise their independent judgment in deciding whether an agency has acted within its statutory authority, and courts may not defer to an agency interpretation of the law simply because a statute is ambiguous. ???? The Chevron doctrine was?"nothing more than a distraction from the question that matters: Does the statute authorize the challenged agency action?" The dissenters in the case, led by Justice Kagan, had concerns that courts won't have the knowledge that agencies have to make decisions. For example: ???? Under the Endangered Species Act, the Fish and Wildlife Service must designate endangered “vertebrate fish or wildlife” species, including “distinct population segment[s]” of those species.?16 U.S.C. § 1532(16); see § 1533. What makes one population segment “distinct” from another? Must the Service treat the Washington State population of western gray squirrels as “distinct” because it is geographically separated from other western gray squirrels? Or can the Service take into account that the genetic makeup of the Washington population does not differ markedly from the rest? See?Northwest Ecosystem Alliance v. United States Fish and Wildlife Serv., 475 F.3d 1136, 1140–1145, 1149 (9th Cir. 2007).

?? Exploring Parallels: Risk Assessment & Wildlife Biology ?? Last week, our colleague Olaf Fülling had the opportunity to attend the annual conference of the Association of German Wildlife Biologists and Wildlife Scientists (Vereinigung der Wildbiologen und Jagdwissenschaftler Deutschlands e.V.). The event proved to be an excellent platform for discussing recent developments in methodologies of wildlife biology. One of the most intriguing aspects highlighted during the conference was the striking similarity between the data collection methods used in wildlife biology and those in higher tier risk assessment. Both fields prioritize profound knowledge of animal ecology and handling, as well as comprehensive data analysis to make informed decisions. Whether tracking animal populations or evaluating potential risks, robust data collection is the backbone of reliable conclusions. The conference underscored the importance of such gatherings as forums for exchanging experiences and developing joint methodologies. By bringing together experts from different disciplines, we can foster a deeper understanding and create innovative approaches that benefit both fields. Kudos to the organizers and participants for creating a collaborative environment that bridges the gap between wildlife biology and risk assessment. Looking forward to seeing the continued evolution of these shared methodologies! #WildlifeBiology #RiskAssessment #DataCollection #Research #Collaboration #MethodDevelopment #teamtier3

How do we measure the 'health', or success, of marine mammal rehabilitation programs? Our new #openaccess paper looks back at more than 2 decades of literature, including 418 publications featuring 52 species of #marinemammals. We found that: -Rehabilitation efforts are strongest for pinnipeds, and North America was the most represented region, although marine mammal rehabilitation happens around the globe; -Data are scarce for both short- and long-term survival across species; -Reports about species threatened with extinction were significantly more likely to include data about conservation parameters than those about species of least concern; -Rehab programs are already collecting a lot of important data to be able to evaluate their success, and a focused effort to coordinate and streamline will benefit many programs. Read the whole paper here, and let us know your thoughts! https://lnkd.in/d5JWvkV5 This research was such a fun collaboration across regions.

Thought this was very helpful -- context and whatnot. Short & clear! Conclusion: << Humans are the True Threat to Birds When rationally viewed, the Smithsonian study and the resulting press flurry has added nothing to the overall conversation about how to protect animals. Instead, it has only drawn attention away from the real threat to birdspeople. Alley Cat Allies wants what’s in the best interest of all animals, including birds. Environmental experts say we must change the way we are impacting our environment. Until we can stop going in circles, perpetuating this false debate, and focus on the real threat, we are truly just chasing our tails. >>

?? State wildlife officials could gain new tools to enforce California’s fur ban through a collaboration between UC Davis California College Town investigators and forensic scientists at the Department of Fisheries and Life State Wild. "Wildlife trafficking is the fourth illegal economy in the world," said Ashley Spicer, senior wildlife forensic specialist at the California Department of Fisheries and Wildlife. California, with its large population and major ports of entry, is a major hub for illegal trade. ?? The problem for wildlife officers is to identify illegal skins and skins rigorously enough to bring cases to court. Processing skins destroys DNA evidence, and skins can be cut into pieces, so an animal cannot be identified by its appearance. ?? The UC Davis lab specializes in extracting genetic information from proteins. Proteins are made of amino acid chains, each of which is encoded in DNA. Therefore, it is possible to compare the amino acid sequences of proteins, and work from these back to the DNA sequence.? The new project aims to change the paradigm of species identification from DNA to protein. The team is building a skin protein reference database of 44 commonly trafficked species. Some of the reference samples come from the UC Davis Department of Wildlife, Fisheries and Conservation Biology Wildlife and Fish Biology Museum. ?? The project will develop and evaluate tools to identify skins, including the reference database and workflows that can be used in forensic laboratories. Making these techniques applicable to samples seized during wildlife trafficking investigations. ??

??? During a trip, you might have already spotted dead animals or carcasses lying by the side of the road. Researchers commonly refer to these deaths as “roadkill,” an issue that negatively affects wildlife populations globally. ?? In a recent study titled “Demographic Effects of Road Mortality on Mammalian Populations: A Systematic Review”, a group of UK researchers gathered published data on 150 mammal populations from 69 species around the world. Then, they compared mammal deaths on roads to key biological parameters, including population size, to determine the effect of roadkill on different animal species. ???? Among other things, they found that roadkill was the most common cause of death in almost a third (28%) of the populations studied – ahead of causes like disease and hunting. In some animal populations, up to 80% of all deaths were due to collisions with vehicles. ?? The book “Crossings: How Road Ecology is Shaping the Future of Our Planet”, by environmental journalist Ben Goldfarb, chronicles the enormous ecological damage caused by roadbuilding and makes a case for highways that are less lethal to animals. ??? More research, initiatives, and projects are needed to reduce the impacts of roads on the wildlife, including but not limited to: - Animal detection systems - Wildlife crossings - Chicanes - Slower traffic speeds - Reconfiguring roads to prevent accidents with animals and humans - Fostering knowledge creation/sharing and scaling up action on road ecology #csls #myklu #factfriday #road #animal Sources: https://lnkd.in/en_PJfRQ https://lnkd.in/ecNG5FgX https://lnkd.in/eRHTij4F

The world’s rarest marine mammal is closer to extinction than ever before. This year’s Vaquita survey has been released - scientists spotted between 6-8 individuals, the lowest number ever reported. Collaboration between local communities and conservationists must be scaled up to ensure fishing practices can sustain locals without harming Vaquitas. Re:wild is committed to helping protect this species on the brink by aiming for a full Vaquita recovery, supporting Sea Shepherd Conservation Society and Vaquita-safe fishing gear and markets with Cetáceos, Acción y Transformación, Pesca ABC and Pronatura Noroeste. Positive steps ahead to save the Vaquita include: using improved acoustic detection devices, measuring Vaquita environmental DNA (eDNA) in the water column to detect and locate other individuals, expanding habitat protection, and training local youth to help monitor the last remaining Vaquitas.

???? Ready for a glimpse into the future of wildlife research? Connect to The 'Internet of Animals.' Scientists are gearing up to track thousands of animals via a new satellite system. This game-changing project will help reveal the secrets of migrations, endangered species, and more, and will transform our understanding of the natural world, ???? #wildliferesearch #internetofanimals #animaltrends #pettrends #causedigital #causedigitalmarketing #icarus #wildlifetech #conservationtech

"Scientists studying migrations, endangered species, and global change are placing tracking devices on thousands of animals that will be monitored by a satellite-based system set to launch next year. If successful, the project could help illuminate the planet’s nonhuman worlds. ..." Would be great to use this technology in a study of wild horses in North America. With the millions of dollars our government is spending to capture and hold horses off range, blaming them for range degradation, perhaps implementing the latest science would offer a more sustainable solution to supporting healthy ecosystems and rangeland. Perhaps they could tag all the players affecting public land, including private livestock and mining facilities, and network of fencing prohibiting natural migration of native wildlife, including horses. #wildhorse #rewilding #grazing #biodiversity
