Poland’s sole high-mountain national park gets its first-ever beaver colony, the park rangers said on Tuesday. The beavers, which have so far limited themselves to scouring the foothills of the Tatra mountains, have scaled the slopes up to the level of 1,100 metres above sea level this winter.
This marks the first time that rodent engineers have been spotted this high. “These are pioneer climbers,” among beavers, ranger Marcin Strączek-Helios is quoted as saying.
The rangers are yet to see the beavers with the naked eye, but the effects of their presence have been obvious since October. Felled trees with trunk perimeter of 10-20 centimetres blocked the Palenica stream near the famous lake of Morskie Oko, creating a pool of water 1.5 metre deep and 10 metres wide.
Two animals, thought to be international migrants from Slovakia, have been caught on camera. The exact size of the colony is yet to be determined.
Tatra National Park boasts views like this, a high peak of 8100 ft, miles of rivers, waterfalls with oohs and ahhs from grateful tourists but is probably best known for its over 650 caves.Many of which are open to the public, including the world famous Demänovská Ice Cave and the breathtaking Demänovská Cave of Liberty.
All of which made me think about the entirely new idea of beavers in caves.
Think about it. Beavers aren’t very keen on eyesight, they live mostly in the dark anyway, have thick fur coats so they won’t mind the cold, and spending 3 months in a frozen lodge can’t be all that different from spending a year in a cave. Of course I had to go looking to see if such a thing ever happened. And what do you think I found?
Eureka! Not only does that make total sense and suggest our Polish friends might be thriving in caves, it also explains the ANCIENT mystery in my mind of how beavers can coexist with alligators, which being reptiles are cold blooded and need more sun than their dam-building neighbors. You can read the rest of the Florida article here, but suffice it to say that the next explorers in those Polish caves shouldn’t be at all surprised if they see this:
Last night we met Danielle from the Academy of Sciences down at the beaver dam. She is writing an article for their new longer web format and had talked to Michael Pollock earlier about beavers and salmon. She said she hadn’t been lucky looking for beavers in Yellowstone but her luck changed in Martinez. She was rewarded with a happy adult sighting and very surprised to find out that beavers were BIG. After she headed home to Oakland mom and kit popped out to say goodbye. A good beaver evening, and thank goodness day light savings is over and we can see them earlier.
