Hiking at Sylvan Glen

Spring is in the air! I had a fantastic time hiking at the Sylvan Glen preserve yesterday. This interesting little preserve is in Westchester county near the Putnam county border. It’s close to Yorktown. I hiked about 4 miles with the hiking group I was with, which didn’t include any joggling since I did that earlier in the day and I didn’t want to distract anyone.

You can get fantastic views in some spots within the park, but be careful. The trails in this park can get very steep in some spots, so you need to be in good shape to make your way through.

The area near the gorge was once an important quarry. It has been abandoned for several decades, but there are still big piles of rock all over the place.

Sylvan Glen also has one of the oldest trees for miles around. This tree is several centuries old. It is probably a white oak, judging by the leaf litter around the tree. It’s been said by some arborists that oaks specialize in not specializing – hence, they grow almost everywhere. I hope this tree survives for another thousand years.

You know its spring when skunk cabbage(Symplocarpus foetidus) starts peaking through the ground. In the north-eastern U.S, it is very often the first green you will see in early spring/late winter. And yes, the plant does live up to its name.

It is an amazing plant due to its ability to produce a lot of heat. According to Craig Holdrege at the Nature Institute:

A couple of times I’ve been lucky enough to see spathes growing up through a thin layer of ice, the ice melted around the spathe in a circular form. This is an indication of skunk cabbage’s remarkable capacity to produce heat when flowering. If you catch the right time, you can put your finger into the cavity formed by the spathe and when you touch the flower head, your finger tip warms up noticeably. Biologist Roger Knutson found that skunk cabbage flowers produce warmth over a period of 12-14 days, remaining on average 20° C (36° F) above the outside air temperature, whether during the day or night. During this time they regulate their warmth, as a warm-blooded animal might!

Skunk cabbage is at best marginally edible if you boil it in 10 changes of water and leave it to dry for a few days. In other words, don’t bother. Native Americans would only eat it when nothing else was available.

If you try to eat it raw or with only a little cooking, the oxalic acid(partially responsible for the plant’s smell) crystals in the leaves will make you feel like you are having holes burned in your tongue.

What is oxalic acid? Oxalic acid is a powerful anti-nutrient that can block the absorption of calcium, iron and other important minerals. Although spinach(and some other vegetables) doesn’t have as much oxalic acid as skunk cabbage, it still has a significant amount. This is one of the reasons I don’t eat much spinach(I prefer kale and cabbage), and strongly advice others to avoid juicing spinach. Cooking spinach can reduce its oxalic acid content, but it won’t eliminate it.

The hike ended just after sunset. I had a great time with some very fun people, although we didn’t get to see much wildlife.

Ghostly boat wreck overlooking Long Island Sound

Boat wreck along the Long Island Sound, in the Bronx. I took the photo, but that is not my boat, I am much better at steering boats than that.

This photo was taken in Pelham Bay Park in the north-east corner of the Bronx, the only borough of New York City that is on the U.S mainland. At 2,766 acres, Pelham Bay Park is the largest park(more than 3 times larger than Central Park) in the entire city, with miles of trails meandering through its many woods and marshlands, as well as along the Long Island Sound and its many inlets.

The diversity of wildlife in this park is remarkable for an urban park. Besides squirrels, it is home to many deer, opossums, hawks, owls, turkeys, cardinals, blue jays, raccoons, turtles, and a few people here and there.

Due to its distance from Manhattan and most major tourist attractions, it isn’t very touristy, except for the Bartow-Pell Mansion(that’s a whole other post) in the middle of the park, but mostly during the summer. Like just about all the parks I visit, it is a terrific place to run and observe wildlife, and you can access Orchard Beach from the park. I first learned how to joggle in this park and in the nearby streets many years ago when I lived closer to it.

Luckily(or unluckily, if you prefer more excitement), the neighborhoods adjacent to the park are not among the Bronx’s most crime-ridden, though I’ve observed drug activity in it over the years. The Bronx and Pelham Bay Park shares its northern border with the boring town of Pelham, and the even more boring town of Pelham Manor, which are in Westchester county.

Green space beneficial for health

It’s always sweet when something we intuitively know gets verified by science. So it shouldn’t come as a big surprise that science has found that living near green space is associated with better health, even after controlling for socio-economic factors. So if you have a significant amount of parkland or woods nearby, consider yourself lucky, even if bears or wolves live in them.

According to J Epidemiol Community Health. 2002 Dec;56(12):913-8.- Urban residential environments and senior citizens’ longevity in megacity areas: the importance of walkable green spaces.

CONCLUSIONS:

Living in areas with walkable green spaces positively influenced the longevity of urban senior citizens independent of their age, sex, marital status, baseline functional status, and socioeconomic status. Greenery filled public areas that are nearby and easy to walk in should be further emphasised in urban planning for the development and re-development of densely populated areas in a megacity. Close collaboration should be undertaken among the health, construction, civil engineering, planning, and other concerned sectors in the context of the healthy urban policy, so as to promote the health of senior citizens.

One of my favorite parks. It is also a supermarket to me, since I love to gather edible plants from here when they are in season

There are few things as refreshing as going to the park to relieve stress, to observe wildlife, to exercise, to meditate, to get bitten by bugs(not very refreshing unless you’re a masochist) or just to explore. As I always say, the larger the park, the better! Besides beautifying neighborhoods, trees also remove CO2 from the air. This is one of the reasons parkland is so essential for human health.

When it comes to exercise, nothing beats a park. If you don’t like indoor gyms(like me), just bring some resistance bands with you to the local park and you can do a total body workout there, besides of course juggling, running, or joggling around it.

Whatever you do, try to promote green space wherever you live. Get involved in park activities or community gardens, plant trees, or even start a garden(indoor or outdoors) to help clean the air. Do it for your own health and for the health of your community.
