Lion population falls 68 percent in 50 years

Lion population falls 68 percent in 50 years | 100 Acre Wood | Scoop.it
African lions, one of the most iconic species on the planet, are in rapid decline. According to a new study in Biodiversity Conservation, the African lion (Panthera leo leo) population has dropped from around 100,000 animals just fifty years ago to as few as 32,000 today. The study, which used high resolution satellite imagery to study savannah ecosystems across Africa, also found that lion habitat had plunged by 75 percent.

"There is evidence of strong declines and even extirpation of lions in some range countries. Especially in West and Central Africa, declines have been dramatic and conservation measures are urgent," the researchers write. "While lions are protected in some of the lion areas, in many they are not, and in others they are hunted."

The study found that 24,000 lions (about 75 percent of the total) are located in ten strongholds, all of which are found in either East or Southern Africa. Tanzania alone contains 40 percent of the global population.

his is the concept that by adding native plants and eliminating chemical use in our properties (and by extension our ecosystems), we can seamlessly introduce habitat restoration to our communities. And the concept goes further- there is rich natural history in this country with almost all of our favorite native plants, the same ones used in a wildlife garden, these native plants have been successfully used medicinally for many generations.

Why I'm Going Native in My Garden

Why I'm Going Native in My Garden | 100 Acre Wood | Scoop.it

... A bigger problem than all of this direct destruction are the nonnative plants, insects and animals that are being transported by human beings all across the globe. Each and every island that we are trying to protect is failing. They are all being invaded by nonnative invasives and we don’t seem to be getting it. Intact ecosystems seem to do okay in battling the invaders, but all it takes is an “in” for them….a tornado….a hiker carrying in seeds on her shoes……a tree dying and a bird dropping a seed. ...

Trading to extinction

Trading to extinction | 100 Acre Wood | Scoop.it
Photographer Patrick Brown spent 10 years documenting the illegal trade in endangered animals in Asia.

 

On 14 February, the UK government is hosting an international conference on the illegal trade in wildlife, at which it hopes to obtain high-level political commitment from governments around the world to fight the issue.

 

According to the government, the illegal wildlife industry is worth more than £6bn each year, and it is growing. Rhino horns can sell for up to £40,000 ($65,000) per kg, making it more expensive than gold. According to Cites - the Convention on the International Trade in Endangered Species - more than 22,000 elephants were slaughtered for their tusks in 2012.

A “Doomsday Book” for Scotland’s woods: real insight into the condition of Scotland’s native woods

A “Doomsday Book” for Scotland’s woods: real insight into the condition of Scotland’s native woods | 100 Acre Wood | Scoop.it

For decades the Woodland Trust has championed the value of Scotland’s native-woodlands to the Scottish Government, the Forestry Commission, councils, landowners, and agencies such as Scottish Natural Heritage. To their credit, many of them did not take much persuading, but this week no-one in Scotland can be in any doubt as to the importance of native woodland to the country.

 

This comes with the unveiling of the final analysis of the Native Woodland Survey of Scotland after more than seven years of comprehensive fieldwork led by the Forestry Commission  to establish an “authoritative picture of Scotland’s native woodlands” covering, location, type, extent, composition and condition; and the results are fascinating.

Death by pest or pesticide? Antibiotic dangers trap bees in a Catch 22

Death by pest or pesticide? Antibiotic dangers trap bees in a Catch 22 | 100 Acre Wood | Scoop.it
Antibiotics used to protect them from bacterial illnesses ravaging hives are making them die from commonly used pesticides, some of which are used to ward-off bee-killing parasites. Matthew Thompson reports.
Antibiotics widely used in the bee industry, such as oxytetracycline, are preventing bees from effectively excreting widely used pesticides.

Honey bees are trapped in a Catch 22 where antibiotics used to protect them from bacterial illnesses ravaging hives are making them die from commonly used pesticides, some of which are used to ward-off bee-killing parasites.

Trees and flooding

Trees and flooding | 100 Acre Wood | Scoop.it

Recent flooding has highlighted the importance of land use in either contributing to or mitigating flood risk. In particular the suggestion that trees might play an important role in helping reduce flood risk.

 

Reports from the Woodland Trust on water and farming and water in towns provide a review of the evidence for the role of trees. Forest Research has also undertaken a significant amount of work looking at the role of trees in delivering better water quality as well as modelling the impacts of increased tree cover on flood risk. These show that trees can make an important contribution both to mitigating flooding and improving water quality.

DAKAR, Senegal (AP) — A conservation group says it is capturing and relocating elephants in Ivory Coast to stave off future conflicts with villagers and townspeople in the first such operation attempted in Africa's forests.

 

The International Fund for Animal Welfare this week began tranquilizing up to a dozen forest elephants outside the western town of Daloa and transporting them to Assagny National Park on the southern coast.

Could bees be dying off because of a plant virus?

Could bees be dying off because of a plant virus? | 100 Acre Wood | Scoop.it

A plant virus has been found in honeybees and could help explain their decline.


U.S. and Chinese scientists have found the tobacco ringspot pathogen, which attacks tobacco plants and soybeans, is increasingly prevalent in declining honeybee colonies.


They say it is the first evidence that honeybees exposed to infected pollen can become infected too.

Worst year yet for SA rhino poaching

Worst year yet for SA rhino poaching | 100 Acre Wood | Scoop.it

More white rhinos were illegally killed in South Africa in 2013 than in any previous year, according to government figures.

 

A total of 1,004 animals were poached, representing a 50% increase over the previous 12 months.

 

Campaigners say that a growing demand for rhino horn from markets in Vietnam and China is fuelling the killing.

 

They are concerned that illegal hunting on this scale threatens the survival of the species in the long term.

 

The White Rhino is one of the world's greatest conservation success stories. At the end of the 19th century there were just 100 alive in South Africa. Today there are around 20,000 according to experts.

Wildlife Gardening Medicine

Wildlife Gardening Medicine | 100 Acre Wood | Scoop.it

Wildlife gardening medicine may just be the future trend needed to turn the tides on the environmental crisis. If people want to have as many native plants growing on their property as possible to ensure there are enough stock plants for their family’s medicinal use harvesting (ie, if people believe there’s something in it for them), then maybe our beloved native plants, even the obscure ones would finally become less marginalized in the landscape.

Vegetable and Herb Gardening at O'Hare: Organic Gardening | 100 Acre Wood | Scoop.it

With the demand for fresh local produce on a upward spiral, so is the demand for growing space. And that, in turn, inspires innovation and invention. A good example of this forward-thinking approach is the Urban Garden at O'Hare International Airport in Chicago. On the mezzanine level of one of the busiest airports in the world, travelers will find a 928-square-foot organic oasis that features nearly 50 kinds of vegetables and herbs. The technique that makes the indoor garden possible is aeroponics, a method of cultivating plants without soil but with a nutrient-rich solution that is misted onto their roots.

How “insect soup” might change the face of conservation

How “insect soup” might change the face of conservation | 100 Acre Wood | Scoop.it

Much of what we know about patterns of biodiversity has come from extensive fieldwork, with expert researchers sampling and identifying species in a process that takes thousands of man-hours. But new technologies may revolutionize this process, allowing us to monitor changes in biodiversity at speeds and scales unimaginable just a decade ago. 

A new paper published in Ecology Letters offers one technological solution to the problem of monitoring biodiversity in real time - Metabarcoding. This method can provide rapid biodiversity estimates from a mashed-up cocktail of specimens nicknamed “insect soup.” It works by simply blending all the samples, then using DNA technology to pick out known species.

What to feed your garden wildlife

What to feed your garden wildlife | 100 Acre Wood | Scoop.it
Feeding garden wildlife has become a regular habit and providing a balanced menu can help keep these welcomed visitors coming back.

 

While gardens can naturally provide an abundance of fruits, seeds and insects, offering tit-bits means nature lovers can provide a nutritional boost during stressful times as well as enjoy watching wildlife from their window.

 

Although it's important to remember that the food you provide is only a supplement - and there are consequences to attracting wildlife to your garden - a few snacks could make a big difference in extreme weather or help to feed demanding young.
