Final NYC Compost Giveback

The Fresh Kills Composting Site in Staten Island
Compost Pickup, Fresh Kills Composting Site, Staten Island

The very last ever, until something changes, NYC Compost Giveback takes place this weekend in the Bronx, and in two weeks in Staten Island. Since there’s no funding in the budget for fall leaf pickup, there will be no more leaves, and no more givebacks, after this.

BRONX

Saturday & Sunday, OCTOBER 4 & 5, 8am to 2pm (rain or shine)
Soundview DSNY Composting Site (at the end of Randall Ave. close to the Bruckner
Expressway)

STATEN ISLAND
Saturday & Sunday, OCTOBER 18 & 19, 8am to 2pm (rain or shine)
Fresh Kills DSNY Composting Site (off West Service Rd. near exit 7 of Rt. 440)

NYC residents and community groups from any borough can get unlimited amounts of
free compost at these events. This high-quality, natural soil enhancer is made out
of leaves that DSNY collected from City residents and institutions.

At the Compost Givebacks, NYC residents can also purchase discounted compost bins
for $20 (subsidized by DSNY-BWPRR) to make their own compost.

Invasive Species in NYC highlighted in Gotham Gazette

Today’s Gotham Gazette highlights the issue of invasive species in New York City as their “Issue of the Week”:

Grounding their roots, literally, in our soil, invasive species come from far and wide, via barge or souvenir-stuffed suitcases, in what horticulturists and biologists across the city call a serious threat to our habitat. Deceiving to the common eye, these foreign born pests and plants raise significant challenges for the city’s Department of Parks and Recreation: monitoring, controlling and even eradicating top the list.

For centuries, New York has been inundated by foreign-born plants and wildlife. Even creatures we now consider common — like our subway or sewer rat — are invasive species. We may have adapted to some of them — whether we wanted to or not — but other more contemporary wildlife pose a serious threat to the sanctity of our natural flora and fauna, say city scientists.
Invasion New York, Gotham Gazette, August 11, 2008

The article provides a broad overview of some of the most damaging, or visible, invasive species present in New York City. I especially commend Gotham Gazette for taking on what I call Brooklyn’s most charismatic invasive species, the Monk Parakeet, Myiopsitta monachus:

The birds have attracted the ire of Con Edison and other electric companies for building huge nest for their colonies on light poles. In Connecticut, a power company, United Illuminated, is seeking permission to kill the birds, while in Florida researchers have proposed mixing contraceptives in with bird seed to limit the parrot population.

The article itself doesn’t use the scientific names of the species mentioned in the article. They are, however, provided for many of them with an accompanying feature, the Know Your Invasive Critters “trading cards.”

Flash Flood Watch for NYC through tomorrow morning

Just in from the NYC Office of Emergency Management (OEM):

JULY 23, 2008 – FLASH FLOOD WATCH IN EFFECT FOR NYC

The National Weather Service has issued a Flash Flood Watch beginning Wednesday
evening, July 23. The Flash Flood Watch is expected to stay in effect until Thursday
evening, July 24. Rainfall totals may reach six inches in New York City, with
localized flooding possible.

New Yorkers should exercise caution, as heavy rain may knock down trees and power
lines, and may create hazardous driving conditions. People should avoid walking or
driving through moving water, as six inches of fast-moving water can knock people
off their feet; two feet will cause most vehicles to float.

Rabies in NYC: Facts and Figures

With all of the recent interest in raccoons and other wildlife, rabies is frequently raised as a concern. The New York City Department of Health has information on rabies on its Web site. Anyone concerned about the risk of exposure to rabies from interactions with wildlife in NYC should review the DOH information, which I’ll summarize here:

  • There have been no human cases of rabies in New York City for more than 50 years. In all of New York State, there have only been 14 cases since 1925.
  • Staten Island, with 29 rabid animals reported last year, and 35 in 2006, has a greater incidence of rabid animals than the rest of the city combined. The risk there is serious enough that DOH has issued a Rabies Alert [PDF, English/Español] for Staten Island.
  • The Bronx, with 14 reports last year and only 6 the year before, has less than half the incidence of Staten Island.
  • Brooklyn has had only 5 rabid animal reports in the past 15 years, and only 1 in the past 5.
  • Although city-wide, raccoons are the most frequently reported rabid animal, in Brooklyn no raccoons have been reported in the past 15 years.

So, although caution is always wise, there’s no need to fear these animals. Except for Staten Island, the risk of exposure is extremely low. Spending time outside in New York City, you’re more at risk from West Nile Virus than rabies.

What is rabies?

(NYC DOH)

Rabies is a preventable viral disease of mammals (including humans) most often transmitted through the bite of a rabid animal. The rabies virus infects the central nervous system. Rabies is almost always fatal once symptoms appear. The vast majority of rabies cases in the United States each year occur in wild animals like raccoons, skunks, bats, and foxes. Animal rabies is reported annually in New York City and State, primarily in bats, skunks and raccoons. New York City first saw rabies in animals starting in 1992, and continues to every year, especially among animals in the Bronx.

In the United States, rabies rarely infects humans because of companion animal vaccination programs and the availability of human rabies vaccine. There have been no human cases of rabies in New York City for more than 50 years. New York State has reported 14 human cases since 1925.

Human rabies vaccine, if administered promptly and as recommended, can prevent infection after a person has been bitten or otherwise exposed to an animal with rabies. The human rabies vaccine is given in a series of five vaccinations along with one initial dose of rabies immune globulin (RIG). The one time dose of RIG and five vaccines administered over the course of one month is referred to as post exposure prophylaxis (PEP).

What Can People Do To Protect Themselves Against Rabies?

(New York State Department of Health)

Don’t feed, touch or adopt wild animals, stray dogs or cats.

Be sure your dogs, cats and ferrets are up-to-date on their rabies vaccinations. [Note: This is the law in New York City.] Vaccinated pets serve as a buffer between rabid wildlife and man. Protect them, and you may reduce your risk of exposure to rabies. Vaccines for dogs, cats and ferrets after three months of age are effective for a one-year period. Revaccinations are effective for up to three years. Pets too young to be vaccinated should be kept indoors. Some new vaccines have now been licensed, and therefore, can be used for younger animals.

Don’t try to separate two fighting animals. Wear gloves if you handle your pet after a fight.

Keep family pets indoors at night. Don’t leave them outside unattended or let them roam free.

Don’t attract wild animals to your home or yard. Keep your property free of stored bird seed or other foods that may attract wild animals. Feed pets indoors. Tightly cap or put away garbage cans. [And your compost bins containing food waste or scraps.] Board up any openings to your attic, basement, porch or garage. Cap your chimney with screens.

Bats can be particularly difficult to keep out of buildings because they can get through cracks as small as a pencil. Methods to keep bats out (batproofing) of homes and summer camps should be done during the fall and winter. If bats are already inside (e.g., in an attic or other areas), consult with your local health department about humane ways to remove them.

Encourage children to immediately tell an adult if they are bitten by any animal. Tell children not to touch any animal they do not know.

If a wild animal is on your property, let it wander away. Bring children and pets indoors and alert neighbors who are outside. You may contact a nuisance wildlife control officer who will remove the animal for a fee.

Report all animal bites or contact with wild animals to your local health department. Don’t let any animal escape that has possibly exposed someone to rabies. Depending on the species, it can be observed or tested for rabies in order to avoid the need for rabies treatment. This includes bats with skin contact or found in a room with a sleeping person, unattended child, or someone with mental impairment. Bats have small, sharp teeth and in certain circumstances people can be bitten and not know it.

NYC Sewer-Stormwater Settlement

New York City will pay $5,000,000 to settle violations from delays in upgrades to sewer and stormwater systems. Three of the four sites to benefit directly from the settlement are in or adjacent to Brooklyn: Gowanus Canal, Coney Island Creek, and Jamaica Bay.

New York City has agreed to pay a $1 million fine and fund $4 million worth of environmental-benefit projects to settle violations related to delays in making sewer-system and stormwater-system upgrades to prevent overflows into waterways. The violations stem from the city’s failure to make improvements in accordance with a schedule outlined in a 2005 consent order. Under this settlement, the city has agreed to a new timeline for completing those construction projects and will make further upgrades to both its sewer and stormwater systems.
Settlement Paves Way for Sewer/Stormwater Upgrades and Green Infrastructure in NYC, July 2008, Environment DEC

The issue centered around New York City’s obligation to improve mechanical structures, foundations, substructures, pumping stations and other infrastructure-related systems. The projects are designed to improve the capacity of the city’s wastewater and stormwater systems. During heavy rainfall in New York City and other municipalities, runoff can exceed the capacity of the sewer system, triggering what’s known as “combined sewer overflows.” [Just as attractive as it sounds.] Infrastructure upgrades can diminish the chances of overflows.

The environmental benefit projects will be concentrated in the Bronx River, Flushing Bay, Coney Island Creek and Gowanus Canal watersheds and will assess the use of various green infrastructure to be installed for sewer-overflow and stormwater abatement. Some of the types of projects that will be considered include enhanced tree pits with underground water storage, rain gardens, green roofs, bio-retention basins and swales, porous pavement and blue roofs. Collectively, these projects are intended to reduce the volume of stormwater that enters the sewer system, thereby limiting overflows. These projects, administered through the state Environmental Facilities Corp., will include extensive community input and involvement.

Bufo americanus, American Toad, by Henry McLin.

The NYC Health Department issued an alert today about an illegal aphrodisiac derived in part from toad venom. A man died last week after ingesting it:

The Health Department today warned New York City residents about an illegal aphrodisiac known as “stone,” which can cause serious poisonings and death. The product is also known as Piedra, Jamaican Stone, Love Stone, Black Stone or Chinese Rock. Last week, an area hospital alerted the New York City Poison Control Center that a man had died after ingesting the aphrodisiac. Similar products were linked to poisonings and deaths during the 1990s.

These products are banned by the Food and Drug Administration (FDA) but are imported illegally. Selling them in New York City is also a violation of the New York City Health Code.
PRODUCT ALERT: ILLEGAL APHRODISIAC CALLED ‘STONE’ CAN CAUSE SERIOUS POISONING AND DEATH

Stone, a hard dark brown substance, is typically sold as a solid chunk less than a square inch in size. It may be packaged in a clear plastic bag with some labeling. The product is sold in some adult stores and can also be found in other neighborhood stores. Its active ingredients include several chemicals known as bufadienolides. They are derived from toad venom and some trees and can disrupt the normal rhythm of the heart.

Local ecotypes available from Oak Grove Farms at Union Square Greenmarket

Handing out shopping bags at the NYC Wildflower Week table at Union Square.
Handing out bags

First thing last Saturday, May 3, I went to Union Square in Manhattan to attend the kickoff of NYC Wildflower Week. There was a table where volunteers and Parks staff handed out tote bags with information about native plants. I didn’t get to stick around for the tours of the native plant garden in Union Square Park. The highlights for me were meeting Marielle Anzelone, Parks Ecologist, and the opportunity to acquire local ecotypes of six native plant species from Oak Grove Farms (changed to Nature’s Healing Farm), one of the Greenmarket vendors:

  • Eupatorium maculatum, Spotted Joe-Pye Weed
  • Helenium autumnale, Sneezeweed
  • Monarda fistulosa, Wild Bergamot
  • Panicum virgatum, Switch Grass
  • Penstemon digitalis, Tall White Beardtongue
  • Pycnanthemum virginianum, Mountain Mint

What’s “native”?

A native plant species is one which grows naturally without human intervention. “Native” is both broad and relative. Native to where? And to what habitat? What ecosystem? Native to North America? The eastern United States? The Mid-Atlantic or New England? Is it native to New York City? To Brooklyn (Kings County)? Are they native to the “wooded plains” from which “Flatbush” got its name?

Most native plants commercially available, especially at the retail level, are selections or cultivars of species. Selecting for more compact forms is common, but selections are made for many reasons: the color of flowers, fruits or fall foliage, for example. In other words, they’ve been selected for their horticultural rather than ecological value.

What’s a “local ecotype”?

Within a species, an ecotype is a genetically unique population that is adapted to its local environment [Wikipedia]. A local ecotype is propagated from local natural populations. In this case, the plants have been propagated by the Staten Island Greenbelt from natural populations of each species occurring in or around New York City.

Local ecotypes are not just geographically distributed. Other important factors are differences in moisture, exposure to sun or shade, extremes of winter or summer temperatures and humidity, and so on. Ecotypes may also differ along these ecological gradients.

Why grow native plants?

In the United States, native plants are enjoying a resurgence in interest and popularity. For the gardener, making choices about native plants comes down to examining and expressing one’s reasons for wanting to grow native plants in the garden.

Growing native plants feeds my curiosity about and interest in the natural world. It’s a way for me to converse with the genius loci, the spirit of the place, where I garden. Most of all, I hope to provide food and shelter for native wildlife, especially birds and insects.

The native plant garden I’m developing in my backyard has a wide range of “native” plants. Many of them are selections and cultivars; some of these, such as a variegated pokeweed, would never persist in the wild. Others are not native to New York City, or even New York state, but to larger ecological provinces such as New England or the Mid-Atlantic Coast.

From growing native selections and cultivars over more than 20 decades, I’ve learned from experience that wildlife value is often reduced or even lost when native plants are selected for their horticultural merits. I’ve grown several different cultivars of Lonicera sempervirens, the native (and non-invasive) trumpet honeysuckle. Hummingbirds have shown little interest in any of them; they may be drawn to my garden by the shape and color of my honeysuckle’s flowers, but they feed on other nearby plants, if they stay at all.

Which is why I’ve always sought local ecotypes of native plants. Unknown millenia of co-evolution with local conditions and other species is encoded in their genetic material. If I want to garden for wildlife, I can do no better than attempt to recreate a microcosm of the natural world where I garden.

Oak Grove Farms

Note: Name changed to Nature’s Healing Farm

Oak Grove Farms, Union Square Greenmarket

Oak Grove Farms, from Clinton Corners in upstate New York, is one of the founding members of the Greenmarket in New York City.

Oak Grove Farms is a family owned and operated nursery in the Hudson Valley. It was started by Lenore & Herman Carvalho as Carvalho Greenhouses over 30 years ago! Their son Tony joined them almost as soon as he could walk and carry a hose.

The farm was renamed Oak Grove Farms about 10 years ago, after the Carvalho name sake: Carvalho means Oak in Portuguese …

Herman and Lenore, are ready to retire now, so Tony, and his new wife, Andrea are picking up the reins. Together they hope to expand, the nursery into a real organic farm, with animals and crops!

Ethics

A final note: never remove plants from the wild. This is poaching.

Ask your sources how they obtain their plants. Early in my urban gardening, I ordered some plants for the wildflower section of the East Village garden. When they arrived, they clearly had been collected from the wild. Removed from their natural habitat to garden conditions, several of them didn’t survive the first year. I might as well have planted cut flowers. I’ve regretted those purchases ever since.

Find and support nurseries and growers that are propagating and growing their own plants. That’s the best way we can increase the demand for ethically-propagated native plants, foster their availability from commercial sources, and protect them in the wild.

Flatbush Facts: Brooklyn’s Noisiest ‘Hood

It makes a body proud. Flatbush is Brooklyn’s noisiest neighborhood, measured by the number of noise complaints to 311.

[In Flatbush] 2,058 noise complaints were made to the city’s 311 hotline from July 1 to Nov. 20. Williamsburg fell just three complaints behind, followed by Bushwick and Brownsville.
Flatbush tops loudest in Brooklyn, NY Daily news, December 11, 2007

This year, DEP complaints in Brooklyn surged by approximately 23%, from 3,914 to 5,101 calls, officials said. Citywide, there were more than 135,589 complaints in the nearly five-month period – about a 25% hike over the same period in 2006.

Brooklyn’s top noise culprit is construction-related din, which is handled by the DEP and clocked in at 2,300 complaints.

Other pesky rackets plaguing the borough include … barking dogs, which annoyed Brooklynites enough for them to dial 311 1,263 times from July until last week. Ice cream truck jingles drew 261 complaints and loud music spurred 119 calls. Car noises, including honking horns and alarms, also made the top-10 list of complaints for the borough.

Gardening as if our lives depended on it

2014-10-13: I just discovered that none of the original links are good. Two web sites linked from this post – Climate Choices, and the Northeast Climate Impacts Assessment (NECIA) – now redirect to the Union of Concerned Scientists (UCS).


I first started writing this post in the Fall of 2006. I drafted it in October 2006, but never published it. I think I was too overwhelmed by the impact of what I was writing to release it. The IPCC report has been issued since then. What I wrote over a year ago no longer sounds so alarmist to me. A post on Garden Rant spurred me to dust this off and get it out there, however imperfect I may think it is.


There’s a lot to this, and I’ve gone through some changes just to take it all in. Here’s the short version:

  • Climate change is inevitable. It’s happening already. We can’t undo the damage we’ve already caused. We can only ride it out.
  • If we continue as we have, the impacts will be severe. It’s going to get really, really bad.
  • Actions we take now can reduce the impact. If we start doing things differently now, it won’t get as bad as it could. We can affect the future.

There are those who cling, at times violently, to ignorance and dismissal of the facts of climate change induced by human activity. “De-nial ain’t just a river in Egypt.” It reminds me of the classical stages of grieving described 40 years ago by Dr. Elisabeth Kübler-Ross, all of which are demonstrated in different responses expressed around this topic:

  • Denial. The three-dog argument – denial, minimization, projection – applies here: There’s no climate change (it’s not a problem). The climate change is within historical ranges (it’s not so bad). It’s a natural process (it’s not my problem).
  • Anger. Protest, boycott, rage against the machine, fight the system, fight the man.
  • Bargaining. Carbon “credits” is the most obvious example. Little different from buying indulgences from a corrupt church.
  • Depression. There’s nothing we can do about it.
  • Acceptance. It’s going to happen. It’s happening. Now what do we do about it?

In July 2006, I wrote about the Bemidji Statement on Seventh Generation Guardianship:

The seventh generation would be my great-grandchildren’s great-grandchildren’s children. (If I had, or were going to have, any children to begin with.) If a generation occurs within the range of 20-30 years, we’re talking 140-210 years. Call it 175 years from now.

It’s the year 2181. It’s hard for me to imagine anything I can do to stave off or reduce the multiple disasters which we will have caused.

That was the voice of depression. I feel some hope now. The changes I make now, the work I do now, can make a difference. But only if I accept what’s going to happen if I do nothing.


A report (PDF) issued in October 2006 details what’s going to happen to the climate of the Northeastern United States – Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, and Pennsylvania – in this century:

The Northeast Climate Impacts Assessment (NECIA) is a collaboration between the Union of Concerned Scientists and a team of independent experts using state-of-the-art tools to assess how global warming will affect the Northeast United States following two different paths: A higher emissions path with continued rapid growth in global warming pollution, and a lower emissions path with greatly reduced heat trapping emissions.


The goal of this assessment is to provide opinion leaders, policymakers, and the public with the best available science as we make informed choices about reducing our heat-trapping emissions and managing the changes we cannot avoid.
Climate Choices in the Northeast, Climate Choice

The [Northeast] region, comprising nine of the 50 US states, is critical, since it alone is the world’s seventh-largest emitter of greenhouse gases, just behind the entire nation of Germany and ahead of all of Canada …


Climate changes already under way will continue to accelerate in the next few decades, whether the high-emissions or low-emissions path is taken, but the results will diverge dramatically by the time today’s newborns reach middle age, the study found.
US Northeast Could Warm Drastically by 2100, PlanetArk

Even the more optimistic, lower-emission scenario – if we aggressively reduce our contributions to global warming – is concerning. If we do nothing, NYC will become unliveable by the end of this century.

The higher-emission scenario … represents a future with fossil fuel-intensive economic growth and a global population that peaks mid-century and then declines. In this scenario, concentrations of atmospheric carbon dioxide (the main heat-trapping gas) reach 940 parts per million (ppm) by 2100—more than triple pre-industrial levels.


The lower-emission scenario … also represents a world with high economic growth and a global population that peaks by mid-century, then declines. However, the lower-emission scenario includes a shift to less fossil fuel-intensive industries and the introduction of clean and resource-efficient technologies. Atmospheric carbon dioxide concentrations reach 550 ppm by 2100, about double pre-industrial levels. Current carbon dioxide concentrations stand at 380 ppm (about 40 percent above pre-industrial levels).
Scenarios and Models, Climate Choice



Over the past 40 years, NYC has averaged 15 days over 90F, and 2 days over 100F each year. In the lower-emission scenario, by the end of the century NYC will have 39 days over 90F, and 7 days over 100F. Under higher (unreduced) emissions, NYC will have 72 days over 90F (five times the current historical average), and 25 days over 100F (ten times the current historical average).

While these urban temperature projections seem to include the overall urban heat island effect, they do not describe surface temperatures, which I wrote about in August 2006. Rooftop temperatures can exceed 150F in the summer. These effects will be amplified even more when the city bakes for weeks and months without relief. We can expect heat-related deaths in the tens of thousands. Heat-related structural failures are not out of the question; the infrastructure of the city was not built with these conditions in mind.

What about winter temperatures? These will also increase. They have already increased by 3.8F from 1970 to 2000. Under the lower-emission scenario, average winter temperatures over the region will increase by 5-7.5F. With higher emissions, we will see 8-12F increase in winter temperatures. The USDA Hardiness Zones are delineated by 5F, so this means my garden is moving 1-2 zones this century, from Zone 7a to Zone 7b or 8a.

For another point of comparison, when things were that much cooler than they are now, NYC was under a mile of ice.


The temperature projections do not include the apparent temperature caused by increased humidity – the heat index – which can make it feel up to 20F hotter. Warmer air can hold more moisture. The increase in humidity will ramp up the heat index faster than the actual temperature.

This map represents how climate will shift in the NYC area through this century. This includes consideration of the heat index. Basically, we’ll be somewhere between Virgina Beach and Savannah.
