In 'Points North' podcast, researchers try to save ash trees from extinction
Are the ash trees doomed?
Mallory Yu, Daniel Wanschura - NPR, Great lakes Now - Mar 3, 2025
Kathleen Knight keeps looking for even more of these lingering ash trees. She finds them in parts of Ohio and Michigan and takes branches from these trees back to Jennifer Koch's lab. There, Jennifer clones them and runs tests to see if there's genetic resistance. And she discovers something amazing. These trees not only have resistance to the emerald ash borer, they actually kill EAB larvae. Scientists really didn't see that coming.

Lynx Canada et lynx roux du Pinacle de Freli/Canada Lynx and Bobcat on Frelighsburg Pinacle
Olivia Hagios - vtdigger.org - December 13, 2024
Over the summer, several Rutland County residents spotted what the Vermont Fish & Wildlife Department confirmed was a juvenile male Canada lynx. Since then, the department has confirmed more than 15 sightings of a Canada lynx moving through the state, suggesting Vermont’s conservation efforts were succeeding ... “The (land conservation) pattern we’re maintaining is integral to all our species,” said Jens Hilke, a conservation planning biologist for the department. “It’s a matter of maintaining what we’ve got instead of building something new.”

“We’ve had 15 confirmed lynx sightings since August,” said a biologist with the Fish and Wildlife Department in a press release Friday. All signs point to the sightings being of the same animal, a young male lynx, she said.
Conservation de la Nature Canada - 10 septembre 2019
Sous l’influence des changements climatiques, on estime qu’au Québec les habitats des espèces se transféreront d’environ 45 km par décennie vers le nord. La province pourrait devenir un refuge climatique pour plusieurs mammifères; elle risque donc de jouer un rôle primordial à l’échelle continentale dans l’adaptation aux changements climatiques. Pour contrer cette menace, il est impératif de consolider et restaurer les zones de connectivité dès maintenant. Ceci implique l’identification de ces secteurs clés pour le déplacement des espèces, l’acquisition de terres positionnées stratégiquement dans les corridors pour les protéger à long terme, l’intégration de ces secteurs dans les règlements d’urbanisme des municipalités et toute autre initiative citoyenne qui viserait à protéger un corridor écologique.
Nature Conservancy Canada - September 10, 2019
In order to survive, all animals, but especially large mammals, need to move to habitats where they can reproduce, feed and find shelter. Vanishing forests and landscape fragmentation is a direct threat to their survival unless we protect the passages, called ecological corridors, which connect natural areas together.Lynx requires a large home range, and its survival depends, in part, on maintaining these connectivity zones. The home range, which represents non-fragmented wooded areas or areas connected by corridors, are essential to a species’ life cycle and activities (reproduction, food, shelter, etc.).

Vermont House bill would ban baiting for coyotes and other furbearers
Vermont House bill would ban baiting for coyotes and other furbearers
Olivia Gieger - VT Digger - March 2, 2025
Though the bill would apply to the broad category of furbearers — including foxes, bobcats or other smaller mammals — the discussion surrounding it has focused primarily on baiting for coyotes ... The Fish & Wildlife interim commissioner, Andrea Shortsleeve, summarized the department’s position in her testimony: “We are not aware of any population issues with furbearers in the state. We are not aware of any disease transmission of scavenging on carcasses, which occurs naturally on the landscape,” she said. “H.132 is trying to address a social values issue. This bill does not address any biological or conservation issues and is not based in science or wildlife management.”
