@movebank.bsky.social just crossed 10 Billion animal tracking locations! Also 10K studies. Thanks for trust of the scientific community to archive such hard earned data there. Working on 'Movebank Neo' for the next 10 Billion

Last post from our Lewis & Clark wildlife resurvey. Lewis wrote to Jefferson that these rivers held more beaver than any streams on earth. It was a business plan & it worked. Here's what's left after that enterprise, and whats come back w/ conservation rolandkays.com/reflections-...

New paper - What could the next 20 years of wildlife tracking look like. Our horizon scan, out today in Proc Royal Soc B, maps out 28 innovations to unlock movement ecology's untapped potential. wildlabs.net/en/article/o...

The last paddle of our Lewis & Clark resurvey took us through a forest of fish trap pilings in Baker Bay. The traps were banned in 1934 but the poles testify to the massive scale of this unsustainable fishery rolandkays.com/paddling-bak...

Retracing Lewis & Clark down the Columbia. They portaged the Cascades in 1805. Bonneville Dam drowned those rapids so we easily paddled through. Watched salmon climb the fish ladder past the counting windows. But 8 dams to the ocean, and it adds up.https://rolandkays.com/paddling-from-bonneville/

April 1805: Lewis & Clark reached the mouth of the Yellowstone and found bison, elk, and pronghorn in numbers that astonished even them. 220 years later, we flew a drone over the same bluffs George Catlin painted in 1832. The land's still there. The animals aren't. 🦬 youtu.be/BCzuZZ69T6c

Beavers build better fish habitat than we do! This awesome dam complex on Idaho state land creates the deep pools and floodplain storage that steelhead need, plus acts as fire resilient sponge 🦫🐟🌲🔥https://rolandkays.com/state-lands-the-beaver-built-salmon-streams/

At Canoe Camp on the Clearwater, Lewis & Clark built dugouts and ran the first serious rapids of their trip. We paddled the same water 221 years later and sat down with Nez Perce experts to learn what's happened to the salmon since. rolandkays.com/padding-the-...

After Lewis and Clark, America nearly destroyed its wildlife. We set camera traps along their route to find out what saved it. Episode 1 of Return of the Wild is live: youtu.be/_Y2yFPKlLVI #WildlifeConservation

Lewis & Clark wrote of bison so thick "the whole face of the country was covered." Yellowstone's Lamar Valley still looks like that. Thousands of bison + wolves & mountain lions. We checked trail cameras to document the recovery. rolandkays.com/yellowstone-wildlife/

Grizzly, wolf, mountain lion, elk — almost the full cast Lewis & Clark saw here is still on the Rocky Mountain front. We spent a day checking trail cameras on the Theodore Roosevelt Memorial Ranch with Boone and Crockett Club. The cameras don't lie. rolandkays.com/roosevelt-ranch-predators/

Stop 2 of our Lewis and Clark Resurvey was to launch or canoes down the Ohio River from Pittsburgh, just like Merriweather Lewis did. rolandkays.com/pittsburgh-p...

4 days, 48 miles paddling the wildest stretch of Missouri River left. Lewis & Clark recorded bison, elk, wolves, and bears here. We found mule deer and coyotes. The cliffs are unchanged. The wildlife is not. rolandkays.com/missouri-breaks-paddle/

In 1832 George Catlin painted the Knife River bluff where Lewis & Clark had wintered with the Hidatsa and Mandan just. We just went back with a drone. The earth lodges are gone. The bluff remains youtu.be/LlmLCoZ0mEg

The Trump administration is dismantling a $368 million deep-ocean monitoring network 900+ sensors tracking climate currents, fishery health, ocean carbon absorption, and coastal flooding along the East Coast. Ships go out in June to start pulling it up. Congress funded it twice after Trump

Observing a free-ranging bison herd on American Prairie lands was the wildlife moment of the trip. The northern Montana grasslands are closer to what Lewis & Clark described than almost anywhere else. Our resurvey cameras are now running here too. rolandkays.com/prairie-conservation/

Students from Aaniiih Nakoda College helped us deploy camera traps on the Fort Belknap Reservation as part of the Smithsonian's Lewis & Clark Mammal Resurvey. Bison, swift fox, black-footed ferrets — this prairie has it all. rolandkays.com/prairie-conservation/

In 1832, George Catlin painted the mouth of the Platte River from this bluff. Lewis & Clark had passed the same spot just 28 years before. We just went back with a drone. Here's what's changed. 🎥 @AmericanArt. youtu.be/jpwHbBl0sB4

Students from Nueta Hidatsa Sahnish College just deployed 40 camera traps across the Fort Berthold Reservation as part of the Smithsonian's Lewis & Clark Mammal Resurvey + tribal wildlife program. Can't wait to see what turns up! rolandkays.com/nueta-hidatsa-sahnish-college-camera-traps/

Prairie dogs have the worst PR team! They run matriarchal colonies, communicate w sophisticated alarm system, and engineer habitat that bison, ferrets, owls, and badgers all depend on. Meanwhile Capybara just vibing & have more followers rolandkays.com/sdsu-prairie-dogs/ @AECheeseman

Meriwether Lewis: "the river is wide, full of large sandbars, the water very rapid and of a yellowish brown colour. Its banks are falling in." Standing on the same Missouri River sandbars today, it fits! One of the only places on the route where that's true rolandkays.com/goat-island-ponca

Lewis & Clark heard their first coyote near here in 1804 a "prairie wolf barking at us as we passed." Now Teresa Graham from Little Priest Tribal College is running camera traps at the same spot, and coyotes are still showing up. 🐺📷 rolandkays.com/adams-homestead

Stop 4: Seeing William Clark's original field journal at the Missouri History Museum. Elkskin binding worn smooth by two years on the trail. Every species we're documenting today started as an entry on these pages. rolandkays.com/forest-park/

Stop 5 of the Lewis and Clark Reurvey: pushing upstream out of St. Louis against the same river currents Lewis and Clark fought for 2,000 miles. Even a few miles is humbling. Reward: 11 bald eagles and a duckling that jumped in our boat to escape one. rolandkays.com/paddling-ups...

Stop 3 of the Lewis & Clark Mammal Resurvey: Tom's Run, WV. Fisher are back. The forest is back. But without wolves or mountain lions, deer have hit ~40 per sq mi, twice a healthy target. Tree saplings need a plastic tube to survive. rolandkays.com/university-o...

Stop 2 of our Lewis and Clark Resurvey was to launch or canoes down the Ohio River from Pittsburgh, just like Merriweather Lewis did. rolandkays.com/pittsburgh-p...

Stop 1 of the Lewis & Clark Mammal Resurvey: a fisher walked into our western PA cameras on its own, a species trapped to extinction here that's quietly returning. Plus beavers, breeding sandhill cranes, and three canid species. rolandkays.com/barkasky-farm/
