7 Ways To Make Your Garden A Paradise For Wildlife

Guest post by Ricky Peterson

One of the joys of having a garden in summer is being able to observe wildlife close up. Whether you’re a bird lover or a fan of butterflies, we can all enjoy watching our feathered, furry and many-legged friends in our own back yard. But how can we attract them to our garden?

The key to making your garden attractive to wildlife is creating a comfortable habitat for them. Here are a few tips to do just that:

Home, tweet home

We all need somewhere to hang our hat, and animals and insects are no different. Set up a bird house in the spring, and you might just be rewarded with a family settling down for the summer. But birds aren’t the only ones who need somewhere to stay – bee houses are also available now, which is great news for our declining bee population.

Also, for an incredibly easy to set up and inexpensive shelter for a range of wildlife, simply lay some logs in a corner of your yard – and don’t bother tidying up fallen leaves. This will provide a home for lots of insects, which could help to eat pests as well as providing a tasty treat for birds. Also, mammals can use the leaf cover to hide food during the winter.

Food, glorious food

Speaking of tasty treats, you can help further on that front. There are lots of mixes of birdseed available, but if you’d like to try to attract a certain type of bird or other animal, try the following.

Mealworms – house sparrow and shrews
Peanuts – great spotted woodpecker and badgers
Fat balls – blue tit and great tit
Nyger seed – siskin and goldfinch
Sunflower hearts – bullfinch
Dog food – hedgehog
Root vegetables – deer

Think carefully about how suitable your garden is for wildlife before you try to attract animals there – are your neighbours as keen as you? Will there be busy roads that could cause danger?

Scrub up well

Ponds and birdbaths are a lifeline for many animals. As well as the fish who might live in your pond, birds can drink the water and use it to bathe, and of course frogs and toads will love the environment.

Blooming lovely

If you want to help the bee and butterfly population to thrive, it’s vital to have both early- and late-flowering plants so that our winged compatriots have plenty to feed on throughout the season. Try some of the following:

Spring: primrose, damson and blueberry
Summer: chives, dahlia and hardy geranium
Autumn: common ivy, sunflower and strawberry tree
Winter: clematis, crocus and honeysuckle

Leave the lawn

Fed up of mowing the grass every week? You officially have a valid excuse for not bothering! As well as the wildflowers that may pop up, a long lawn is a great haven for lots of wildlife. Insects will love it in the summer, and it may come in useful over winter for hibernating mammals.

Of course, you don’t need to let nature take over completely
even just a small patch will make a difference

Toxic love

Chemicals are not the friend of wildlife – as well as killing off the pests, they can harm or even kill the predator. If you’ve used chemicals in your garden but want to cut back, have patience. If your garden is varied enough, the predators should keep the pests in check, but you need to allow time for the ladybirds to return before you go spraying those aphids (and killing off the ladybirds, too).

Live and let live

Most importantly, show the wildlife in your garden respect – even though you might not love the beetles, they have a part to play in its ecosystem. Remember, too, to treat the wildlife as wildlife, and try to limit human interaction with animals – becoming dependent on you could be dangerous for them.

Enjoy creating your own wildlife paradise!

SALAMANDERS IN CRISIS! An Overview of Why Salamander Conservation is Needed

Guest blog by Matt Ellerbeck, founder of Save the Salamanders

Although they are rarely given much thought, and often overlooked when they are, salamanders are in a terrible crisis. Around half of all the world’s salamander species are listed as threatened by the International Union for Conservation of Nature (IUCN). These species are all facing a high risk of extinction. A further 62 species have been designated as near-threatened with populations rapidly dwindling. This means they are quickly getting closer to threatened status and to the brink of extinction. Sadly for some salamanders it is already too late, as both the Yunnan Lake Newt (Cynops wolterstorffi) and Ainsworth’s Salamander (Plethodon ainsworthi) have already gone extinct.

Salamanders have been on the earth for over 160 million years, and the terrible state that they now find themselves in is due to the detrimental acts of humans. Even those species that are not experiencing population declines deserve attention and conservation to ensure that they remain healthy and stable.

One of the biggest issues affecting salamanders is the loss of their natural habitat. Many areas that were once suitable for salamanders to live in have now been destroyed for developmental construction and agriculture. Habitats of all kinds are being lost at an alarming rate. Wetlands are drained, forests are logged and cut down, and waterfronts are developed. Salamanders are literally losing their homes and they are losing them rapidly. The expansion of urban areas threatens the suitable habitats that still remain.

Where natural habitats do still exist, they are often fragmented or degraded. Fragmentation occurs when healthy areas of habitat are isolated from one another. These fragmented areas are known as habitat islands. Salamander populations are affected since gene flow between the populations is prevented. This increases the occurrence of inbreeding, which results in a decrease in genetic variability and the birthing of weaker individuals.

Fragmented populations where inbreeding occurs often ends in a genetic bottleneck. This is an evolutionary event where a significant percentage of the population or species is killed or otherwise prevented from reproducing. Habitat fragmentation is also harmful because it often eliminates crucial requirements in the area which are critical to the survival of salamander populations. Such areas include spaces that can be utilized for thermoregulation, prey capture, breeding, and over-wintering. Without such habitat requirements populations dwindle.

Breeding sites, often in the forms of vernal pools are particularly important. The loss of such areas in the form of habitat destruction can negatively affect the entire population and its reproductive output. According to the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), there is some evidence that certain salamander species have individuals that return to the pond in which they were born once they reach maturity. Therefore, destruction of a breeding pond may result in loss of the entire population returning to that site. Habitat complexity is also important as it offers shelter to salamanders from both predators and human persecution.

Degradation occurs when the natural habitat has been altered and degraded to such a degree that it is unlikely that any remaining salamanders species would be able to survive. Developments and agriculture near fragmented habitats put salamanders at serious risk. As amphibians, salamanders have extremely absorbent skins. Industrial contaminants, the introduction of sedimentation into waterways, sewage run off, pesticides, oils, and other chemicals and toxic substances from developmental construction sites and human settlements can all be absorbed by salamanders. This can quickly lead to deaths. They can also cause widespread horrific deformities to occur. A study conducted at Purdue University found that out of 2,000 adult and juvenile salamanders 8 percent had visible deformities.

According to Save The Frogs, Atrazine (perhaps the most commonly used herbicide on the planet, with some 33 million kg being used annually in the US alone) can reduce survivorship in salamanders. Many products are sold with the claim that they are eco-friendly. However, these should be viewed with caution. For example, according to N.C Partners in Amphibian and Reptile Conservation, Roundup and many other surfactant-loaded glyphosate formulations are not labeled for aquatic use. When these formulations are applied to upland sites according to label instructions, the risk to surfactant-sensitive species is considered low. While this may be the case for fish it does not necessarily apply to amphibians. Salamanders that breed in water also routinely use non-aquatic areas and could easily be exposed to glyphosate formulations that contain harmful surfactants through direct application and not just incidental drift.

Habitat destruction and degradation can also effect the availability of prey items, causing unnatural declines in appropriate food sources.

Habitats are often isolated and cut off from one another by the roads and highways that now run through them. Countless numbers of salamanders are killed on roads and highways every year when they are hit by vehicles. Salamanders that are migrating to breeding and egg-laying sites often must cross over roads to reach such areas. Here many of the mature members of the breeding population are killed. Removing members of the breeding populations greatly limits reproductive output, this makes it incredibly hard for salamander numbers to rebound.

Roads present an additional problem because they represent a form of habitat loss. The roads that run through natural areas also fragment the existing populations, drastically making them smaller in size. This limits the gene flow and genetic diversity between the isolated populations on either side and this greatly increases the chances of extirpation. When salamanders attempt to cross roads to travel between the populations, or to critical breeding/birthing sites it greatly increases their chances of being hit and killed by vehicles.

The Wetlands Ecology and Management (2005) population projections for spotted salamander (Ambystoma maculatum) life tables imply that an annual risk of road mortality for adults of greater then 10% can lead to local population extirpation. Unfortunately, it is estimated that mortality rates can often be as high as 50 to 100%, which means populations are at extreme risk of extirpation and extinction due to road mortality. Wyman (1991) reported average mortality rates of 50.3 to 100% for hundreds of salamanders attempting to cross a paved rural road in New York State, USA. Given that this figure pertains to a rural area from over a decade ago, it is fair to assume that even higher mortality rates occur as their has been in increase in cars and roads over the years. Reducing road mortality is paramount to preserving salamander species.

Being hit and killed by vehicles is not the only threat that roads create for salamanders. Chemical run-off from vehicles contaminate roadside ditches and pools. These sites are often utilized by salamanders for breeding and birthing. According to Steven P. Brady (2012) survival in roadside pools averaged just 56%, as compared to 87% in woodland pools. Thus, an average of 36% fewer individual embryos survived to hatching in roadside versus woodland pools.

Salamanders are also threatened when they are harvested from the wild. Salamanders are taken for the pet trade, for food markets, and for use as fishing bait.

There is much about salamanders that scientists do not know. Aspects of the biology, ecology, and lifestyles of many species is a mystery. This undoubtedly means human interference is negatively affecting salamanders in ways in which we don’t even know. The intricate relation between all species and the vital roles they play within eco-systems is also being altered. Such alterations can have serious consequences to not just salamanders, but many other animals as well (including humans).

The Benefits of Organic Lawn Fertilizers

Guest post by Philip Brown

Now-a-days, it is totally possible to care for your beautiful lawn organically. Organic lawn care is the practice of caring for your lawn and garden by using organic fertilizers. This becomes what is known as ‘sustainable’ lawn care. With environmental concerns for children, pets, and wildlife when trying to get rid of pests and weeds, there are beneficial ways to care for your lawn with organic lawn fertilizers. There are a few methods that one can try to maintain their lawn that are great for the environment:

Compost or compost tea:
Reduces the need for chemical fertilization and encourages healthy soil that allows turf to resist lawn pests.
Lawn aeration:
Helps in getting oxygen into the soil as soil gets depleted of nutrients and organic matter. It also helps reduce thatch and lessen soil compaction.
Rechargeable electric mulching mower:
Reduces the need for fertilization. It is quiet and inexpensive and environmentally friendly. The mulch and compost can be used together and raked over the aerated lawn, which invigorates the turf and strengthens and rebuilds weakened structures.
Corn gluten meal:
Beneficial in controlling stinkweed, black medick and shepherd’s purse. This is relatively new in organic lawn care.
Nematodes:
These are microscopic parasites that destroy insect pests, which you can spray on the lawn to control the crane fly, June beetle or Japanese beetle.

There are many other organic fertilizers on the market that benefit lawn maintenance. Whether it is a small piece of personal land or a company or tourist attraction with lots of land to display and care for, caring for the lawn and maintaining it in ways that are beneficial to the environment and cost effective is great.

There are so many ways to care for one’s lawn. Just following these methods is a great and easy way to start caring for your lawn in an environmentally healthy way. Simple things, such as aeration and building compost, to use as organic fertilizer are the first steps. Having a rechargeable electric mulching mower to add grass clippings to the compost makes caring for the lawn and fertilizing it that much easier. Adding in things, like the corn gluten meal, to control weeds and nemotodes, as a natural insect control are also beneficial and eco-friendly. There are many advantages to organically taking care of your lawn, no matter what method you use.

Good news for endangered California frogs

We were happy to learn that a few days ago the California Fish and Game Commission voted unanimously to designate two species of native yellow legged frogs inhabiting high-elevation lakes in the Sierra Nevada and Southern California mountain ranges as threatened and endangered species under the state’s Endangered Species Act. The commission acted after the Center for Biological Diversity filed a petition outlining the decline.

According to the Center, the population of Sierra Yellow legged frogs has decreased by 75% in recent decades. Reading about these frogs, we were struck by how they are a symbol of the challenges that frogs face worldwide. But they aren’t facing one challenge—they seem to be facing almost all of them:

Introduction of nonnative species: Stocking of nonnative trout in high-elevation Sierra lakes has been the main cause of the species’ decline. The trout eat tadpoles and juvenile frogs and alter the food web of the aquatic ecosystems on which the native frogs depend. The Department is recommending no trout stocking in the state without a fish management plan, and no further stocking of trout in areas that would conflict with protecting yellow-legged frogs.

Pesticides: Recent research has linked pesticides that drift from agricultural areas in the Central Valley to declines of native amphibians in the Sierra Nevada. Pesticides and other pollutants can directly kill frogs and also act as environmental stressors that render amphibians more susceptible to diseases, including a chytrid fungus that has recently ravaged many yellow-legged frog populations.

Loss and degradation of habitat: Grazing, logging, water diversions, off-road vehicles and recreational activity are allowed in frog habitat.

Climate change: Climate change has brought warmer temperatures, decreases in runoff, shifts in winter precipitation in the Sierra from snow to rain, and habitat changes that are rendering frog populations more vulnerable to drought-related extinction events.

A recent settlement agreement with the Center for Biological Diversity, which will also speed protection decisions for 756 other species, requires the U.S. Fish and Wildlife Service in 2013 to make a decision about whether to add the Sierra frog to the federal endangered list.

See the Center for Biological Diversity for more information about these frogs and about the other endangered species they are working to protect.

What's Really Scary: A World without Bats

It’s almost Halloween and what animal is more associated with this spooky holiday than any other? The answer isn’t frogs, it’s bats.

Unlike frogs, however, which seem to have lots of human friends and supporters, bats have few. Most people find them pretty creepy. They’re associated with vampires and other scary things.

I learned about bats many years ago when I lived in Ohio. When I visited friends’ homes out in the country, bats would often emerge at sunset, and they were quite beautiful, flying up into the sky. I also watched a swarm of bats emerge at sunset from Carlsbad Canyons in New Mexico (see video below), a daily natural spectacle.

Did these bats make a beeline for the humans so they could bite them and suck their blood? No. They ignored us humans completely, focused instead on finding some tastier prey—mosquitoes and other insects.

Unfortunately bats seem to be sharing the fate of frogs and bees—they are vanishing because of a mysterious fungal disease. As Sandra Steingrabber writes in Raising Elijah: Protecting Children in an Age of Environmental Crisis: “The possible contribution of pesticides and climate change to the bats’ malady is a topic of discussion among field biologists—as is the synchronous vanishings of fungal-afflicted honeybees and frogs.”

In 2006 scientists found hundreds of dead bats inside several caves across the country—all had white muzzles, the result of a fungus. Bats with this white-nose disease were subsequently found in 115 different caves from Tennessee to Quebec. The fungus grows on the exposed skin of a hibernating bat and causes the bat to wake up, behave strangely, and burn up its fat reserves, thus starving to death.

The disease has claimed the lives of a million bats across 19 states. More than half of the bat species in the United States are in severe decline or are listed as endangered.

A World Without Bats

So what would the world be like without bats?

Imagine being swarmed by insects and bitten by mosquitoes from head to toe. Imagine pests wiping out agriculture across the country, causing produce prices to go up.

If the decline of bats continues these scary scenarios could be our reality.

We need these spooky, fast-flying mammals that can eat 1,200 insects in an hour, protecting us from the West Nile Virus and other deadly diseases.*

So this Halloween, amid all the Batman and vampire costumes, don’t forget that bats are pretty amazing—and important—animals that need our help. One way you can help bats is to build a bat house. Here’s some information from the National Wildlife Federation.

Here’s a video of Mexican free-tail bats emerging at sunset at Carlsbad Caverns in New Mexico, to eat their evening meal of millions of insects:

How Do Hurricanes Affect Wildlife?

After Hurricane Irene, Susan posed the question to me: what happens to wildlife during a hurricane? I decided to try and find out the answer to this. Because Irene affected such an enormous area—from North Carolina to New England—it’s difficult to generalize. I began with the National Wildlife Federation’s Seven Things to Know about How Hurricanes Affect Wildlife, which I’ve summarized below. Please see the NWF site for more information.

Wind Dislocation

The powerful winds in a hurricane can blow birds off course and push them away from their home habitat. While songbird and woodland birds can cling to branches, and woodpeckers and other cavity nesters ride out the storm inside trees, sea birds and waterfowl are exposed to the high winds.

Other tree dwelling animals are also effected. During Irene, many baby squirrels were orphaned after being blown out of their nests in trees.

Tree Loss

Loss of coastal forests and trees can be devastating to wildlife dependent on the trees for food and habitat. High winds will often strip trees and bushes of food for wildlife: fruits, seeds, and berries.

Dune and Beach Loss

Storm surges, wave action, and winds can cause beach and dune erosion, which has severe effects on species, especially those that live in ecological niches in the sandy areas and dunes of coastal barrier islands. Sea turtle nests, for example, can be washed out, or a water surge, called a “wash over” that can submerge these nests. Tern and plover nesting areas may also be affected. In some cases, the storm can cause an entire beach area to disappear.

Saltwater Intrusion

The sustained and powerful winds of a hurricane may cause salty ocean water to pile up and surge onshore. These storm surges can be huge. Hurricane Irene’s surges brought water levels that were as much as 8 feet above normal high tide. In addition to the physical damage this causes, the salt contained in sea water dramatically shifts the delicate balance of freshwater and brackish wetland areas. Creatures and vegetation that are less salt-tolerant may be harmed and many may not survive this influx of sea water.

Freshwater Flooding

Heavy rains generated by hurricanes dump water in coastal area river basins (called watersheds) and this, in turn, can send vast amounts of fresh water surging downstream into coastal bays and estuaries. This upsets the delicate and finely tuned freshwater/salt water balance that can be so vital for the health of these ecosystems.

Turbidity

Heavy rainfall in upstream areas also washes soil, sediment, and pollutants into coastal and marine environments. Similarly, sediment can wash over coral reefs, blocking needed sunlight.

Marine and Aquatic Species

Hurricane Irene generated massive waves and violent action on the surface. When hurricane Andrew hit Louisiana the government estimated that more than 9 million fish were killed offshore. Similarly an assessment of the effect of that same storm on the Everglades Basin in Florida showed that 182 million fish were killed.

Close to Home

Where I live in Hoboken, New Jersey, many of the city’s residents (including my family) were subject to a mandatory evacuation because of the danger of flooding; in worst case scenarios, possible storm surges were predicted to cause water to rise to the second story of the city’s apartment buildings. While the flooding wasn’t as severe as predicted, we did notice that the water on the sidewalks, in our basements, and backyards smelled toxic. Considering that this water flows into storm drains and eventually into waterways is disturbing. This “witch’s brew,” as it was called in various news reports, consisted of raw and partially treated sewage, chemicals from industrial facilities, bacteria, oil, and gasoline.

This commentary by Jeff Tittel in the New Jersey Newsroom.com about the possibility of this toxic brew being released during hurricanes from New Jersey’s many superfund sites was disturbing:

The New Jersey DEP only has one inspector reviewing institutional controls and caps and ensuring flooding and other impacts do not impact the controls. We have 118 superfund sites, 16,000 contaminated sites, and 7,000 sites that have been remediated, some of which are very complex. There are about 500 toxic sites near our rivers and about 3,500 are located near groundwater sources and 500 near major water supply wells. Flooding and polluted stormwater could result in toxins from these sites entering our waterways.

The other day I heard about a woman in Hoboken who sloshed around in the water in flip flops the day after the hurricane and who now has a serious infection. I could smell this toxic brew right in my own flooded basement and backyard. This can’t be good for wildlife (or for people either).
