Welcome to our blog,
FROGS ARE GREEN!

For over 200 million years, ponds, marshes, grasslands, and rain forests have come alive with the calls of frogs. Yet these remarkable and colorful animals are declining at such a rapid rate that they are being called the Earth’s next dinosaurs. According to the IUCN Red List of Threatened Species, a third of the world’s amphibian species are threatened with extinction. To read more, click here!

Creating a wildlife-friendly backyard

Monday, August 9th, 2010

As Susan and I are hosting family and friends, we are reposting a couple of our favorite or most popular posts this week. We have edited the posts for the season or to update some material. Enjoy and hope you’re having a great summer!

It’s that time of the summer when we’re spending a lot of time in our backyards tending gardens that by now might have become out of control. Sometimes we spray and clip in a vain attempt to keep nature at bay and to make everything look tidy.

I read an interesting article in The Independent (UK) , “Why Untidy Gardens Make the Best Habitat for Wildlife.” My in-laws live in England and “garden” more or less means the same as “backyard” to Americans, though most English yards have a flower border. British readers, please correct me if I’m wrong!

Anyway, the article points out that town and city gardens provide a vital refuge for birds, insects, and other animals, including amphibians. Small gardens are as good as large gardens, urban gardens as important as suburban ones, and non-native plants are not always harmful to birds and insects.

Both city and suburban backyards can provide what Harvard biologist E.O. Wilson calls “bridges” between protected areas, providing refuges for wildlife. These bridges serve as a vital corridor, for example, for amphibians, migrating songbirds, and other animals.

My city backyard, in a densely populated small city, falls into the category of “untidy.” I have a lax attitude as to what I allow to grow in it, including a Norway maple, which no one in my family likes. They claim it’s taking over the tiny backyard, which is true. Yet the tree also draws lots of birds. I have vines growing up walls that provide places for birds to hide in, and I have a birdbath. I don’t use pesticides or herbicides.

What I’ve noticed is that every year I am getting more and more animal visitors, and a greater variety, too. This year in addition to sparrows and mourning doves, I’ve seen cardinals, robins, and other songbirds. In the fall, I have bird visitors that eat the grapes on my grape vine, swooping down almost the same week each year.

You don’t have to do much to make your backyard a wildlife habitat. Just don’t be too neat—don’t hurry to clear up everything when the garden stops flowering. Some of this “debris” is important for wildlife to hide in or to eat.

Of course, I realize that some animals are pests and steps have to be taken to keep them out. When we’re in New Hampshire, we need to use special bear-resistant garbage cans. Some parts of the country have real problems with deer.

But I think we should try to give a helping hand to those animals and insects that need these wildlife bridges—amphibians, birds, honey bees, and so on.

Here are some more tips for fall planting from the Independent article:

  • plant large shrubs—shrubs and trees produce more vegetation where wildlife can live and eat
  • allow at least some flowers to turn to seed and let the lawn grow tall.
  • create a pond for insects and frogs, or buy or make a toad abode
  • don’t illuminate your garden/backyard at night with bright lights. This will disturb many nocturnal creatures
  • create a compost heap—they are miniature nature reserves in themselves.

See also the National Wildlife Foundation’s site about gardening for wildlife and about what you need to do to get your yard recognized as a Certified Wildlife Habitat.

Other tips:

  • Put out a bird bath. I enjoy watching birds splash in it every morning.
  • Put out bird feeders. Yes, the squirrels eat the seed, but mostly birds eat it. I buy a big bag of wild bird seed at the supermarket.

Update: After this post ran (10/09), we got lots of interesting comments, so we asked people to send in pictures of their wild backyards. These photos are still up (see gallery). We’d love to receive pictures of your wild backyard and are looking for guest posts about how to create a wild backyard.

Teach Your Children Well (about nature): Father’s Day Thoughts

Sunday, June 20th, 2010

A couple of months ago, we received a lovely email from a reader named Marty who lives in in Eastern Pennsylvania (Lehigh County) one hour south of the Pocono Mountains.  Here’s part of the email:

What’s  the best thing I can do as a Dad to teach my children to preserve these treasures [frogs and salamanders] that are so dear to me. My grandfather taught me the love of wild places and I want to pass that on to them.

I wish more dads were thinking about how they could introduce nature to kids. My sons are in their twenties and still love learning about wildlife and animals. I think most of this love of nature came from their father. So I’m offering a few suggestions. But we’d like to open this up to readers of Frogs Are Green and get your ideas also. How did your father encourage your love of nature? What are you doing as a dad to instill a love of nature in your kids.

Here are some ideas:

• take them on short hikes or walks into the woods, starting when they are very young. (Here is a list of state parks). Young children need no encouragement to love nature—everything around them is still magical and interesting (bugs, stones, flowers).  The key is to keep taking them on walks in the woods throughout their childhood, even when they start saying it’s boring (the preteen years). You might have to add other incentives during the rougher times (a trip to an ice cream store afterwards or some other treat).

• Your child might start to like one animal and that may become their animal. Encourage this by buying books about the animal, plush toys, trips to see the animal in the wild (whale watching trips, for example), or in zoos or aquariums.  You can adopt various wild animals for $25 or so, and this will give your child a personal connection to the animal (we adopted a whale when our sons were young).

• Plan family vacations around national parks rather than amusement parks. We’ve visited a number of national parks over the years. These are fun because the trails through them are easy and well worn, there’s a certain familiarity to them (the park rangers, the gift shops, etc), and the scenery is spectacular. You can buy a passport for your child and have it stamped in each national park you go to.

• Share you enthusiasm about nature, but don’t be too heavy handed about it. If kids feel you are always teaching them, they might get turned off. Instead, share your sense of wonder. Point out a cardinal (look at that red bird!), but don’t turn it into a lesson about birds.

• The National Wildlife Federation has ideas about enjoying nature with children, including setting up a tent in your backyard and sleeping outside. I did this a few times as a kid in my suburban backyard (without the tent), and loved it. If you’re lucky enough to live in a place far from cities, you can stargaze with your children, pointing out a few constellations.

• as far as our amphibians friends….the best places that we’ve found to see them are state parks. Unlike Marty, we live in an urban area and it’s tough to find amphibians in a region where all the land has been developed. But state parks and wildlife refuges that have been left untouched, with ponds and swamps, are great places to see them. Tell your kids to look out for frogs, toads, and salamanders. Kids are closer to the ground and have sharper eyes and will most likely see them before you do. You can also build a frog pond in your backyard.

Dads: Please send along your ideas as well for introducing children to nature! Happy Father’s Day!

A Field of Nightmares? Atrazine, Corn, and Frogs

Wednesday, January 20th, 2010

I’ve always had a sentimental attachment to cornfields—from the magical cornfield in Field of Dreams to the real cornfield across the road from a house I lived in during college years. My mother was born and raised in Iowa and I’m descended from farmers.

But chemicals, in particular Atrazine, used as herbicides on cornfields might be poisoning frogs (and people), and turning fields of dreams into fields of nightmares.  These herbicides run off cornfields into streams and rivers, and leak through the water-treatment process, contaminating groundwater and drinking-water supplies.

Last summer we blogged about the problems of Atrazine. Research by University of California, Berkeley professor  Dr. Tyrone Hayes, for example, has shown the effects this chemical—an endrocrine disruptor—has on frogs. It can cause birth defects and reproductive problems, including such bizarre deformities as male frogs with eggs in their testes. This past week, as reported in the Washington Post, new research at the University of Ottawa found that when exposed to Atrazine fewer tadpoles reached froglet stage. Atrazine appears to affect estrogen in humans as well and has been connected with ferility problems, cancer, and birth defects.

The EPA, under the Obama administration, has launched a review of the chemical that will continue until fall 2010. It will look closely at Atrazine and other endrocrine disruptors, which might result in tighter restrictions on their use. While this sounds hopeful, Atrazine’s primary manufacturer, Syngenta, has strong ties and influence within the EPA. (Atrazine is banned in Europe, where perhaps industry and government aren’t as closely intertwined as they are in the U.S.).

The Froglog: A Frog-Friendly Invention

Monday, January 11th, 2010

Last summer we received a wonderful photograph taken by Mary Lascelles for our photo contest of a frog (whom she named Fritz) who hung out on the filter line in her pool sunning himself. Luckily, Fritz never fell in the pool.

Unfortunately many frogs do fall in pools and are poisoned by chlorine, which is absorbed into their bloodstream through their permeable skin. Recently on the Mother Nature Network blog, I read about a new invention, called a froglog, that helps frogs and other small animals escape from pools.

The froglog was created by Rich Mason, a wildlilfe biologist with the U.S. Fish and Wildlife Service, who was disturbed that so many frogs and other animals were dying in pools. The froglog is a thick foam tile with angled edges that allow frogs to climb out of the pool. The froglog can also be used in hot tubs, spas, fountains, and backyard ponds.

As Mason writes on his website, due to suburban sprawl, pools are now often built close to the natural habitats of amphibians. He mentions a friend with a pool in Maryland who found over 50 animals trapped in his pool in one night.

Check out this video of frogs and turtles using the froglog escape ramp. And if you have a pool and live in an area with lots of wildlife, definitely consider getting a froglog!
