The use of herbicides, pesticides and fertilizers:
A new study by researchers at Case Western Reserve University and the Holden Arboretum suggests that changes we are making to the environment have the potential to make animals more susceptible to diseases and therefore may lead to population declines.

Their study suggests that human-made changes to the environment may be damaging the immune systems of a species of frog whose populations have drastically declined since the 1970s.

This research shows that land use–farming or treating lawns with herbicides, pesticides and fertilizers–can influence traits that protect animals from disease.

“By improving our understanding of the factors influencing immune defense traits capabilities, we are given the opportunity to make changes to our land management practices to better protect wildlife health” Dr Krynak said “and in all likelihood, our own health as a consequence.

*** During this pandemic we are experiencing the close connection between disease in wildlife and our own species. We are all connected on this planet, and so our human behavior can cause animals to be more susceptible to disease, and this can lead to profound consequences we do not yet fully understand.


Rodenticides: 

We are learning more and more about chemicals used on the landscape of farms and their effect on all the other life present there. And the picture has become very clear regarding the connection of using rodenticides…poisons to kill rodents….and the suppression of the immune systems of carnivores. It is they who hunt and eat the poisoned rodents. This has been observed in cougars, owls and other birds of prey, bobcats, coyotes and foxes.

Again, when their immune systems are compromised, they are much more susceptible to disease. One of these is mange, caused by millions of microscopic parasites that invade their skin and hair follicles. The parasites suck their blood causing severe anemia, destroy their hair follicles causing them to lose all their fur and violently scratch, leading to open weeping sores. With a severely suppressed immune system, members of these species die a slow and painful death.

As a farmer, why should you care about this?

For your farm to be healthy and productive, you want to have healthy wild ones living there with you. If for no other reason, it is to YOUR benefit.  There is so much we do not know about the workings of our amazing planet and her marvelous Life…..SO

Walk gentle upon the Land……

Is Your Farm an Ecosystem in Balance?

We live in a time when we are experiencing worldwide disruption of the Earth’s diverse ecosystems. And as a result of these profound disruptions, worldwide pandemics of disease, as well as local epidemics like the Lyme disease in eastern North America, continue to plague life as we know it.

Human Health is inextricably tied to the health of animals and the environment.

Human health is tied to the health of animals and the environment BUT our human behaviors are also tied to the rest of life on our planet; human behaviors are causing profound disruptions and are the underlying cause of the massive spread of disease today.

And these behaviors are uncontrolled human population growth, and this leading to humans taking over vast areas of the planet. This leaves very little space for the rest of life to survive, many wildlife forced to live in close proximity to humans. In addition, our large carnivores are being wiped out by the continued perceptions of the past.

And as wildlife habitat is destroyed, biodiversity is lost. And when biodiversity is lost, so is the resilience of the life forms left behind, causing them to more easily succumb to disease. Add to this the serious and outright killing of major carnivores whose presence, protects and supports biodiversity, and keeps their prey populations in balance.

SO YOUR FARM is a microcosm of Earth’s larger ecosystems. Your farm is an ecosystem that can be disrupted or it can be one that is rich and biodiverse. And when your farm is in balance and biodiverse, the Earth will protect you from disease that can affect both your farm animals and you.

Dayton Hyde, a highly respected rancher and writer shared his experiences regarding the value of an important carnivore on his ranch. This is what he had to say:
“I thought of other species on the ranch. Without flickers, badgers, trout, deer, or chipmunks, the ranch still would have flourished. But if I took away the Coyotes, the whole system fell apart. In fact, if I were to design a kit for the beginning rancher, a pair of Coyotes would have to be included.”

Carnivores like Coyote play THE vital role in protecting from disease and keeping the balance by the part they play in the predator-prey relationship. So you want to make sure you save a place for them on your farm. You want them to be present, and you want them to thrive …so you need to make sure there is habitat and plenty of prey for them. If you do……THEY WILL TAKE CARE OF YOU!

A Tale of Two Farmers

Note: the electric fencing and Guardian dog photo by Billy Foster

As a wildlife biologist, my work focuses on our recovering carnivores and our relationships with them. Supporting our farmers is important to me because they not only feed us, but here in Maine there is such an effort to farm sustainably. I make regular trips to our weekly Farmers Market, but also give presentations collaboratively with several of our leading farmers.

On one particular Saturday at the Farmers Market, one of our farmers requested that I might help another new one who had just come to Maine after retiring. So I thought I would stop by and chat with him to offer any support he might wish. What I found out from him was this: he raises very vulnerable lambs in a rural area, allows them to be born out in the field, and he has NO electric fencing and NO guardian animals.

So basically he uses no animal husbandry practices to protect them, in fact he informed me that he refuses to do so. Instead he kills any coyotes that he sees. As we all know through so much research on this subject, there will be no end to his losses because of his behavior.

He sees the Coyote as the enemy, instead of viewing them as intelligent beings who he can come to understand, and with whom he can share the land.  However, a door needs to be open for new learning to take place.

Then I walked over to another farmer and we had a short chat. He was a young farmer who told me that he loved hearing the Coyotes howl, and in his words:  “I want to learn more about them.” Such a simple statement, yet it is very powerful. The desire to understand our fellow beings is the first step to living very successfully with them.

AND SO THE CONTRAST~ Experiences like these have made me more and more aware that we are living in an amazing time of transition. So we are seeing those who refuse to make use of successful animal husbandry practices, who see Coyote as the enemy, and continue to see killing as the answer. YET we are also seeing more and more young farmers embracing what works AND at the same time not seeing Coyote as the enemy but as a fellow being of our planet Earth. THEY GET IT! This is the farming of the future happening today.

It is the CONTRAST that lets us know how much further we have to travel on the road to the farming of the future.

The Benefits of Multispecies Grazing

Here is just another way to farm successfully, in the company of carnivores: Multispecies Grazing. Actually this form of farming mimics nature for there is always a diversity of grazers in a healthy natural ecosystem. And when there is this biodiversity on your farm, it all comes into balance, is resilient and healthy.

Our wild predators recognize SIZE when they seek out their prey. Large herbivores can be and are a serious threat to them, and they will think twice before attempting to hunt in their presence. So in the presence of cows, llamas or donkeys, your sheep are much safer from predation.

BUT ~ there is also what is referred to as predator pressure. This pressure can either be slight or great. You can participate in making it be slight. First: provide sufficient habitat on your farm for the carnivores AND their prey. By doing so you are allowing them to have a good living without looking toward your farm animals for sustenance. Second: protect your resident carnivores, especially ones like Coyote, Cougar and Wolf who have complex social systems. By supporting the presence of a stable family group, you protect your farm from all others.

This is the FUTURE OF FARMING!

The Biggest Little Farm

We would like to highly recommend this excellent film of John Chester and his wife Molly. It was their goal to create a farm that would be ecologically healthy and robust.  And so they set out on an adventure with results they could never have imagined.  So let them take you on this journey.

But we would leave you with this thought ~ What they discovered was the immense importance of the predator prey relationship in order for their farm to be successful. They did not use this scientific term, instead they experienced it.

And finally, note how their relationship with Coyote taught them some powerful lessons: lessons about how we humans view different predators…the ones we fear, such as wild canines and snakes, and ones we do not fear, such as owls and hawks.

You may need to watch this film more than once. And every time you do, you will realize something new!

Lyme Disease and your Farm’s Ecosystem

Lyme disease has become an epidemic in the United States. The bacterium, Borrelia burgdorferi, that causes it, and the vectors that carry it continue to create an unbroken cycle of this disease.  In fact the bacterium that causes it is present worldwide, and it is a highly evolved bacterium.

Epidemics are not like the flu that comes once a year and then is gone. Instead they are a manifestation of a serious lack of balance in the ecosystem on Earth. Here in the United States, the dramatic changes in the landscape due to the clear cutting of 97% of the forests of the continent, along with the killing of immense numbers of our important carnivores were the beginnings. And as a result of these initial behaviors, the populations of the white footed mouse, the carrier of the bacterium, reproduced in great numbers as did the deer, whose large bodies the adult ticks breed and feed upon.

Scientists in this country are struggling to understand this bacterium that is causing this epidemic, an epidemic that is growing exponentially every year. BUT if we do not see ourselves as members of a larger community of life, and recognize what we really need to do to end the epidemic, it will continue. 

BRING  BACK  BALANCE  TO  ECOSYSTEMS.

SO YOUR FARM ~ Recognize your farm as an ecosystem that needs all its members. Protect yourself from this epidemic by welcoming carnivores like Coyotes especially, to create the balance…by hunting the rodents and keeping the deer on the move and their numbers in balance.

THE EARTH HAS ALL THE ANSWERS….WE NEED TO LISTEN.

Creatures of Empire

Historians write that it is important to know the PAST so that we can come to understand the PRESENT, and by doing so create a more enlightened FUTURE.

So I wish to share with you this excellent book, Creatures of Empire, by author Virginia De John Anderson.  It is a book that anyone who cares for livestock on their farm should read.

How did the colonists from Britain and elsewhere in Western Europe view their animals? How did our Native Peoples view wild animals, (as they did not make use of domestic livestock)?

And how did the Europeans view the Land and how it would be used by their livestock?  And what about the wild animals, especially the carnivores…how did they view them?

This ideology that became entrenched in the East moved westward over time. Can we learn anything from these relationships that changed our continent, our wildlife and ourselves?
