North American Bird Species Threatened By Climate Change

The shift north of species     image credit: National Audubon Society via npr.org

I heard David Yarnold, president and CEO of the National Audubon Society, on NPR talk about a new seven-year study the organization has done that warns that the migratory routes and habitats of more than half of the birds in North America are now or soon will be threatened by climate change.

I still hear arguments against climate change forecasts that are sometimes labeled as "alarmist" but Yarnold says that "... there are forecasts that are far more extreme than this report. If anything, this report is conservative. At every step of the way, we took great care to not overstate data or conclusions. Nothing would make us happier than to be wrong about the fate of many of these birds."

The study, "314 Species on the Brink," look at the entire continent, but you can look close up at New Jersey.  The bald eagle, a species that in New Jersey has finally been brought "back from the brink" of being extirpated and endangered, could see its current range decrease by nearly 75 percent in the next 65 years.

"This colorful little falcon is in serious trouble in some parts of the continent. Yet populations are stable or increasing elsewhere. With the American Kestrel and so many other geographically widespread species, it is essential to engage management and conservation on a region-by-region basis. The Audubon model forecasts overall winter gains and summer losses for the species, but the bigger story is substantial northward movement of suitable climate space at both times of year. The decline of nesting American Kestrels in the northeastern U.S., well along already, seems likely to proceed, perhaps to the point of regional extirpation in New England and the Mid-Atlantic states."

The common loon, an iconic bird in Minnesota and Maine, may no longer be able to breed in the lower 48 states as soon as 2080, according to the report.

The story highlighted Baltimore orioles, a species that is so beloved in Maryland that their major league baseball team bears its name. These orioles are migrating birds and by 2080, there may not be any orioles left in Maryland because they could be forced to nest well north of the state.

In talking about the pace at which this change is happening, Yarnold says:
The report looked at North American birds. It's not likely that birds are going to migrate from Central and South America to replace them. But, remember, what we're talking about are changes at a pace and a scale that we've never seen before. These are the kinds of changes to habitat that have taken tens of thousands of years in the past. And what worries me is that these are the kinds of changes that my 9-month-old grandson could see in his lifetime.

Course offered for those interested in wildlife rehabilitation

Were you that kid who brought home the bird that couldn't fly and the injured wild animal? Then maybe you are the adult who would be interested in a program from the NJDEP Division of Fish and Wildlife.

If you are interested in wildlife rehabilitation, and especially interested in becoming a licensed wildlife rehabilitator, then you will want to attend a Wildlife Rehabilitation Training Course.

The next offering of the course will be at Mercer County Community College on November 3-7, 2014.

This course is an alternative route to meet a portion of New Jersey State permitting requirements for wildlife rehabilitators. Successful completion of the course will count for 40 hours toward the 200-hour New Jersey apprenticeship permitting requirement.

This course is available to anyone wishing to gain knowledge about native New Jersey wildlife.

An injured baby raccoon is treated at the Woodlands Wildlife Refuge.
During spring and summer it is not uncommon for people to cross paths with young, seemingly orphaned or injured wild animals. What would you do? Should you feed it? Was it abandoned? Should you take it home? Is it hurt? Is it sick? Does it have a disease you should be worried about contracting?

The course includes wildlife rehabilitation history, licensing requirements and regulations, mammal, bird and reptile species identification and anatomy, proper handling, care and nutrition, medical procedures, and much more.

The cost of the course is $499 and registration information can be obtained from Mercer County Community College by calling 609-570-3311.

This announcement can be found at http://www.njfishandwildlife.com/news/2014/rehabcourse.htm on the Division 's website.

The Eastern Garter snake is not endangered but, like most snakes, it is misunderstood and often misidentified. It is commonly seen throughout New Jersey and can be mistaken for the Eastern Ribbon snake.

You are likely to encounter this snake inside or underneath logs, wood piles and mulch piles, although they may also be found on a lawn, hunting or basking themselves in the sun.

The Garter snake is quite harmless and there is no reason to remove or harm them. If the snake feels threatened, it will emit an unpleasant odor in hopes that the predator moves away.

If a predator grabs its tail, the tail will break off and the broken portion will continue to move around as the snake escapes from the predator. The tail section can grow back.

Garter snakes eat insects, salamanders, small frogs, earthworms and will hunt day and night.

Though most snake species lay eggs, the Garter snake will give birth to 30-50 live young.

Learning About New Jersey's Great Swamp

The Great Swamp was created approximately 15,000 years ago. The Wisconsin Glacier pushed its way during the Ice Age and in its melting poured into the natural basin known as the Passaic Valley to form Glacial Lake Passaic.

What we call the Great Swamp is what remains of that huge lake which has continued to drain via the Passaic River and many other smaller rivers and creeks.

If the name Great Swamp doesn't sound like an appealing place to visit, you need to look beyond the name. It is not entirely swampland but rather a mixture of marshes, meadows, dry woods and brush-covered swamps.

These four habitats are what make the Great Swamp unique and allow the area to support a wide variety of plant and animal life.

The Great Swamp is one of NJ's 5 National Wildlife Refuges. Their website offers this advice to visitors:

People are encouraged to observe, study, photograph and walk with nature in designated public areas. The best times for observing wildlife are early in the morning and late afternoon. Because of large number of visitors in the spring and fall, wildlife viewing on Sundays is often less rewarding. The refuge has close to 10 miles of foot access trails, with varying difficulty from which wildlife can be viewed. There are also three wildlife observation blinds and one wildlife overlook. Pleasant Plains Road is a good place to view wildlife from your vehicle. The Great Swamp National Wildlife Refuge also recommends that you visit the Raptor Trust (for information please call 908-647-8211), the Somerset County Environmental Educational Center (for information please call 908-766-2489) and the Morris County Outdoor Education Center (for information please call 973-635-6629). There is also the Watchung Reservation, Morristown Historical Park, Sherman Hoffman Aubudon Center and several other outdoor recreation areas located close to the Great Swamp National Wildlife Refuge.

Frelinghuysen ArboretumIf you visit, there are well maintained trails and even boardwalks that allow you to observe without doing harm to the habitat. (This is not a place to bring pets.)

Plants vary in size from the tiny duckweed to the towering red oak. As the seasons change, so does the color of the area - yellow marsh marigold to the blue iris.

One way to learn more about this living, breathing botanical and zoological resource is with a visit to the Great Swamp Outdoor Education Center. which is part of the Morris County Park Commission and offers many environmental programs for all ages.

 If you live in the area, you may want to become involved in the volunteer opportunities there too.

A Big Ten Rutgers Tomato

Last week I received alumni mail about Rutgers' inaugural Big Ten football season. I also read a NJ Monthly article about attempts being made at Rutgers to bring back the famed Rutgers tomato.

Rutgers football may be just entering the Big Ten this fall, but the Rutgers tomato was in the Big 10 of tomatoes starting in the 1950s. For several decades the Rutgers tomato reigned in popularity for its Jersey tomato taste. It was tart, sweet, tender, round, red and ripened on the vine.

Companies, like Campbell Soup, loved them for juice, soup and ketchup. So why use the past tense when talking about this variety? It fell victim to commerce.  As the interstate highway system expanded in the 1950s, more produce was being trucked longer distances. The soft Rutgers tomato did not travel well. Scientists worked on developing varieties that did travel.

Those newer hybrids were firmer with thicker skins and interior walls and could be ripened after picking.  And they tasted lousy.

I have been a backyard gardener since I was a kid helping my father. We planted Rutgers tomatoes. My father saved seeds from the best ones for next year. But I moved on to buying plants at the garden center and at some point in the 1980s the Rutgers plants disappeared.

Lots of cherry tomatoes in July. Pop them in your mouth right in the garden

My tomatoes only travel about 100 feet, so "shippability" doesn't matter - taste does. The next generation tomato from Rutgers was the Ramapo, developed in 1968 which had a good ten-year run, disappeared and the was reintroduced in 2008. It tastes like a Jersey tomato, but doesn't ripen until August. Gardeners and farmer like a product in July.

"Heirloom" tomatoes were big for a few years. Those are varieties that go back pre-WWII. Nostalgic, but flawed for the same reasons that they fell away in the 1950s; they cracked, softened in heavy rain, got fungus and other diseases and you ended up throwing too many away. So much for nostalgia.

It probably surprises folks that New Jersey, even with its disappearing  farmland, still ranks fourth in the nation in value of agricultural products sold per acre.

The tomato that we often find in stores now is pretty dreadful compared to what I can pick in my backyard.  Stores, and many consumers, want firmness and picture-perfect fruit. Now that a lot of production is in Florida, California and Mexico,  those supermarket tomatoes are picked green and then gassed with ethylene to turn a sickly red, then refrigerated for shipping. Tomato gardeners know that you never refrigerate your tomatoes unless you want to halt ripening.

I have to plant one yellow tomato for my sister - a fan of the "low acid."
My mom showed me the gassing method without knowing the science. Put some half-ripe tomatoes in a brown bag with a few slices of an apple and close it up. She couldn't tell you why it worked, but it did. It didn't taste like one picked off a plant, carried into the kitchen, sliced and eaten with a little salt, or olive oil and some oregano., but better than the store-bought ones that she called "greenhouse tomatoes."

The Rutgers agriculture people have been working to resurrect the Rutgers tomato we once knew and are down to a dozen or so contenders from several hundred. It will be a Rutgers tomato reborn.

They have been having a Great Tomato Tasting for the past few years (this year's will be at the end of August) where regular folks taste and rate.

The new name is still undecided. "Rutgers250" is a possibility to mark its debut in 2016 which is the 250th anniversary of the college. We'll see if it tastes like the summer of 1962, but hopefully it will taste like summer.

Are Bees Endangered?

I was having a conversation with some friends about this blog and someone said, "Why don't you write about bees. Aren't bees endangered?"

Turns out that people are paying attention to the news articles about the disappearance of bees. But bees (and there are so many species - and we don't mean wasps and yellow jackets) have not made the official endangered lists.

Even kids that watch Jerry Seinfeld's Bee Movie know that one-third of our food depends on the services of a pollinator—bee or other insect, bird, or mammal.

Bees are the most important pollinators in the Northeastern U.S., and there are hundreds of species of bees that live in our state.

National Honey Bee Day is August 17. It's a good time to celebrate honey bees that pollinate many of our important food crops like apples, broccoli and blueberries - and then there is that wonderful honey.

You might have read that there have been many problems with bees in New Jersey and across the country. Scientists are still not sure if the cause (or causes) are fungal, viral or from toxic pesticides.

Bees are one of the issues for the Natural Resources Defense Council.

In 2006, beekeepers became vocal about disappearing bees. Seemingly healthy bees were abandoning their hives, and this became known as Colony Collapse Disorder (CCD). Estimates are that nearly one-third of all honey bee colonies in the country have vanished.

Scientists have not come up with a definitive answer to the the problem. Factors seem to be pesticide exposure, invasive parasitic mites, an inadequate food supply and a new virus that targets bees' immune systems.

We know from other endangered species that when species disappear it is often an early indicator of problems that will affect humans. For example, bees that pollinate crops that are sprayed are more likely to die off than bees that pollinate in the wild.

Have you have ever thought about having your own hive? Check out the  NJ Beekeepers Association which has chapters throughout the state.

Open Space

Legislation to advance open space funding passed the state Assembly today by an overwhelming margin. The Assembly voted 58 to 9, with one abstention, in favor of a measure to allow voters to decide on funding for preserving parks, open space, farmland, historic sites and flood-prone lands. According to the NJ Conservation Foundation , without the Assembly's critical bipartisan vote, there would have been no chance of renewed land preservation funding for another year.

Established in 1960, New Jersey Conservation Foundation is a private, not-for-profit organization. Our mission is to preserve New Jersey's land and natural resources for the benefit of all. Through acquisition, stewardship, advocacy and partnerships, we save land, manage environmental resources, promote strong land use policies, and forge alliances in order to permanently protect open space, farms and urban parks all over New Jersey.

5 National Wildlife Refuges in New Jersey

New Jersey
The U.S. Fish and Wildlife Service’s Northeast Region encompasses 13 states from Maine to Virginia. About 70 million people, nearly a quarter of the nation’s population, live within this area where the Service’s nearly 1,000 employees work in the regional headquarters, field offices, national wildlife refuges or fish hatcheries. Many of these 132 facilities are open to visitors and can provide exciting opportunities for wildlife dependent education, recreation and interpretation.

Part of the U.S. Department of the Interior, the Service conserves, protects, and enhances fish and wildlife and their habitats for the benefit of present and future generations. Service biologists contribute to the health of our environment — and consequently our quality of life — by protecting and restoring important habitat, safeguarding endangered species, minimizing environmental contamination, and restoring fish populations. In addition, the Service provides funds to support state fish and wildlife programs and enforces federal laws protecting wildlife.

In New Jersey, we have five Wildlife Refuges: Cape May National Wildlife Refuge (NWR), Edwin B. Forsythe NWR, the Great Swamp NWR, Supawna Meadows NWR, and the Wallkill River NWR.

Tidal Wetlands, Supawna Meadows National Wildlife Refuge - USFWS.gov photo

Not as well known to residents as the Great Swamp and Cape May Refuges, the Supawna Meadows National Wildlife Refuge is located in Pennsville, New Jersey. The refuge area is found along the Delaware River estuary just north of the Salem River in Salem County, NJ.

It is part of the larger Cape May National Wildlife Refuge and recognized as wetlands of international importance and an international shorebird reserve. The refuge currently owns approximately 3,000 acres. The tidal marshes that comprise nearly 80 percent of the refuge provide waterfowl with an important feeding and resting area, particularly during the fall and spring migrations.

The refuge supports visiting populations of black ducks, mallards and northern pintails during winter. Sandpipers and other shorebirds use the refuge marshes as a feeding area in summer and throughout seasonal migratory travel. Delaware's nearby Pea Patch Island Rookery hosts over 6,000 pairs of nine species, which make it the largest rookery of colonial wading birds on the east coast north of Florida. The marshes provide valuable foraging habitat for these colonial wading birds during the nesting season.

Warblers, sparrows and other migratory birds use the upland areas of the refuge as resting and feeding areas during migration and for nesting during the summer. Thousands of tree swallows forage on the refuge in the late summer. Ospreys, bald eagle, northern harrier, short-eared owl and barn owls also nest on the refuge.          Download the refuge brochure
