We have a really great video for you today about the ongoing efforts to keep the Bronx River clean and healthy.

The Bronx River–which runs through a dramatic gorge in the Garden–is New York City’s only freshwater river (the Hudson is a tidal estuary as far north as Troy, and the East River is a tidal strait). The river’s transformation from a dangerously polluted waterway in the mid-20th century to the healthy, clean home of New York City’s first beaver in 300 years is an ecological success story, with new chapters written daily.

So sit back and enjoy this trip down the Bronx River in a flotilla of canoes manned by volunteers from the Bronx River Alliance and a team of Garden horticulture interns.

Water came to rebuke the too clear water.
One drop fell from a fern, and lo, a ripple
Shook whatever it was lay there at bottom,
Blurred it, blotted it out. What was that whiteness?
Truth? A pebble of quartz? For once, then, something.

For Once, Then, Something — Robert Frost

The story of José and Justin Beaver is a tale of two tails.

In case you’re unfamiliar with the furry duo, perhaps we should offer an introduction. You see, José Beaver is no ordinary beaver. José is, in fact, the first confirmed beaver living within New York City limits in the more than 200 years since his furry forebears were hunted and trapped into local extinction for their luxurious pelts. Beavers were once so important to New York City they are featured on the city’s seal, and frequently act as adornment on buildings around town (and in place names, too).

So, you can see why such a fuss was made when José’s very existence in New York City was confirmed. José is a living link to history. And it only got better when, in October, the existence of José’s pal was confirmed. In a nod to popular culture, he was dubbed Justin Beaver (though, it remains possible that Justin may one day be deemed a Justine–beavers are notoriously hard to sex).

Head below the jump for more on why José and Justin are more than just cute, furry face.
