Finback Whales

Yesterday, I was in Ocean City, New Jersey for a meeting regarding the rain garden I'm designing for the intermediate school.  I actually spent the preceding weekend there with friends, as there's nothing better than a wintry weekend at the beach in front of the fire.    Yesterday morning, I finally mobilized to go for a long run.  While normally I run along the boardwalk, I feared the damp rainy weather would make the boards too slick, so I opted for running north along through the salt marshes north of town and to the neighboring town beyond (I took a photo on the way, and will post on an actual plant tomorrow or Wednesday). 

It's probably just as well I avoided the boardwalk, as I would have only had my iPhone when encountering this:


This is a fin or finback whale, which washed upon the shore of Ocean City, New Jersey early yesterday morning.  I heard the news at my rain garden meeting and quickly went to see the whale myself when the meeting concluded.  


Authorities from the Marine Mammal Stranding Center identified the species and estimate that this animal measures approximately forty to forty five feet long.  That makes it an juvenile, as mature fin whales reach lengths of seventy feet, making them the second longest whales and the sixth largest living animal in the world (after other whales, of course).  Their narrow bodies account for their discrepant rankings in length and size, it also is why some refer to them as 'greyhounds of the sea' -- they are incredibly agile and fast. 


Unfortunately, this whale washed to the shore dead, which anyone could surmise the instant they got of their car a few blocks away.  The smell hung in the air, and yesterday's heavy fog almost seemed like tangible evidence of the odor. A similar whale was sighted a week earlier in New York harbor; it's likely that the whale was struck by a ship in the harbor, died and slowly drifted with the currents until it ended up in Ocean City. Fin whales are endangered.  Like many others of their relatives, the fin whale was heavily hunted during the 20th Century.  Wikipedia cites that between 1904 and 1979, 750,000 species existed in the southern hemisphere alone.  Today the total fin whale population is closer to 15,000.  Though the International Whaling Commission bans the hunting of fin whales, Japan, Iceland and Greenlanders continue to hunt the species. 



Despite the odor, I'm pretty sure every year-round resident of Ocean City (and perhaps others from further away) made it to the beach at one point yesterday, in order to see the whale.  Parents brought their children, excited for them to see such a large living thing.  Of course, some kids (like the boy two photos up) are more interested in playing with the sand -- some people are just never impressed. By the way, that cop in the foreground, on the right, yea... he's totally yelling at me to get off the jetty.


I thought it was literally awesome to see such a large animal, particularly now that I know it was barely over half its mature size.  We all learn that the ocean is inhabited by strange, massive animals and certainly that's why there is no shortage of wonderful organizations to preserve our ocean ecologies, but to really witness, with my own eyes, physical proof of such a massive mammal is moving.

I've already linked to a few organizations that make it their mission to protect whales and or the ocean, but let's not forgot Save the Whales - even if the pins aren't as popular!

The Senator Falls

So, those of you who are up to speed on your big tree news may already know this -- but one of the world's largest trees collapsed in flames last weekend.  It was one of those news oddities that got picked up on morning radio stations and when I heard the story, you can imagine I went straight to the interwebs to investigate more.  


'The Senator' as the tree was lovingly nicknamed, was a baldcypress growing in Longwood, Florida.  Today I was on the National Mall and snapped a few shots of The Senator's genetic cousin, Taxodium ascendens. Baldcypresses can be the East Coast's largest trees and The Senator was designated in 2006 as the largest tree (of any species) east of the Mississippi.  It was estimated to be about 3,500 years old, ranking it as the fifth oldest tree in the world.  


While this species on the mall is probably about 50-65' high, The Senator was 165' high until 1929 when a hurricane topped it.  Shortly before its demise the plant stood at about 125' - just 25' shy of the Statue of Liberty.  The diameter of the trunk measured at just over 17'.  That's probably about 5-6 times bigger than the tree in these photos.  Those dimensions are quoted in this article, though it should be noted that arson is no longer being considered as a source of the fire that ultimately felled the tree.  


Balcypresses are given their name since they are deciduous cypresses, losing their leaves in the winter, which is a rare occurrence for a gymnosperm (i.e. non flowering plant).  The habit is upright and conical.  The plants thrive in swamps and saturated conditions.  It's this tolerance to anaerobic conditions that have lead to its more frequent use as street trees (since the conditions under concrete sidewalks are similarly limited in oxygen).

Kenilworth Aquatic Gardens

Last Saturday, my students and I had class at the Kenilworth Aquatic Gardens.  If you haven't been (and you live in the DC area), definitely check it out.  We lamented the fact that we were just a few weeks too late to enjoy what had to have been an amazing show of lotus (Nelumbo nucifera).

Here are a few photos.  I'll elaborate on a few new species later in the week. 

Enjoy!

Yellow Flags

I'm sort of teasing readers this week -- I made a mention of visiting Meridian Hill Park and have yet to share photos yet.  I haven't had a chance to really read up on the history of the park, but hope to have a post for that by Friday.


In the meantime, here's a glimpse of the water feature that is the key part of the park's design and, flanking the goblin's face, Iris pseudacorus or yellow flag iris.  Below, note how short the standards (upright petals) are, compared to the falls (the lower petals).


Yellow flags are European plants and are quite invasive in the United States -- they are very tough plants and are even used for treatment of sewage and for removing heavy metals from contaminated sites.  That said, in a site like this, it's a shame a native aquatic iris, such as Iris versicolor (purple flag iris) couldn't have been used.
