TREE XENOPHOBIA




Tree xenophobia is common in South Africa and people cut down trees for no real reason like blaming the tree for making leaves that fall in the swimming pool or the roots making the lawn lumpy (Africa is not for sissies).

It is actually heart warming to see an effort being made to save an alien (it does not occur here naturally) Norfolk Island Pine in the village of Schoenmakerskop where I live. I call it a great architectural innovation but I suppose it is just a gap in the wall to allow the tree to continue standing where it has been for some sixty years. Does this happen elsewhere in the world? It is the first time I have seen this. The tree, being mature, won't expand that much more and the gap in the wall between the wall and the tree is so small that even a Dachund on a weighless programme would not get through.

Incidentally another Norfolk Pine got struck by lightening and I was expecting to get some great images but there was only some damage to the bark and a meter long shallow gauge on the trunk. I expected more and in the back of my head I seem to remember that the sap in the tree is heated by the bolt, expands and can cause the tree to shatter. I suppose I can blame the drought.

True Confessions of a Naturalist/Photographer




I am supposed to earn my living from photography and writing but sometimes the naturalist in me takes over. Driving in a small municipal nature reserve along a fence I saw a small antelope and managed to switch off the engine and coast to a silent stop, grab a camera and fall silently out of the car. The small antelope continued feeding along the fence and eventually passed me.

Watching I realised it was a Blue Duiker, the smallest antelope found in Southern Africa. You seldom see them and in some 35 years of photography the only ones I have seen were dead alongside the road or dead in a snare. My camera sounded like a machine gun in the quiet of the morning and the antelope quickly realised it was not alone. It nervously approached the road and hesitatingly stepped over to the other side. Still using a slow almost ponderous walk it went to a track leading into thick bush and in a blink skipped down the path and disappeared.

Wonder how long it will take before I see another. Interesting how large the hooves seem, an expert (thanks Ayesha)(will tell the world to visit the Kragga Kamma Game Park!) told me that it was the result of the soft sandy habitat it lives in. If the surfaces it walks on are not abrasive the hooves will grow. They are not rare but are seldom seen because of their secretive habits and dense habitat of dense coastal dunes. They are most active early in the morning and late at night.

Sadly they make good eating and are easily snared. Crossing roads is also not their forte and I chose this picture because it shows how secretive they are and how hard they try to avoid being seen. This antelope walked back to the shadow across the road and crossed in the shadow. Good camouflage but not good road sense.

I do like the white edged tail which makes identification easy. It is almost like a little flag that identifies it. Next time I will remember that I am a professional photographer and will take more than just a few pictures. I might never see another one.

Painted Reed Frogs


I probably spend a bit too much time around my little fish pond. I ignore the Raucus Toads (too noisy) and keep an eye on the Painted Reed Frogs.

At night it is all sex and music. The adults sit on the lily pads and surrounding vegetation and make their not unpleasant “short, high pitched, explosive whipp-whipp whistles, repeated once every second.”* They do this in a massed choir and it certainly works well for them and there are many happy couples clasping each other in the water and tadpoles in the pond. So many in fact that we have a new visitor, a Fishing Spider, that is providing a bit of tadpole population control.

It is not what happens at night that has caught my attention, it is how the frogs disperse during the day that I find fascinating. The total population of Reed Frogs is about 20. During the day there are at most 4 around the pond and the rest go and hide in the garden. I find their choice of hiding places interesting.

It makes good sense for a young frog to spend the day in the rain gauge. A frog would want to know if there was rain as it would enhance the night’s activities if there was more water – although the only time they go into the water is to escape predators or mate. Completely inexplicable is one frog (I call him Herbert the Invisible) who sits in full sunlight in the middle of a brick wall in full view of all predators (who range from birds to snakes). He (or she) persisted in doing this and eventually there were 3 “invisible” wall sitting frogs. One brave frog sat in an aloe for about 3 weeks, every day on the same sharp and thorny leaf. His bright colours made him stand out against the dark leaf. Again it did not really make sense.

Stranger still are the Painted Reed Frogs who like the pink or orange buoys. We live near the sea and cannot leave a buoy lying on the beach and the garden is full of them. They ignore most colours and if you really need a frog looking in the pink buoy is almost guaranteed to be successful. They don’t like yellow or red and tend to ignore all the other buoys.

My favourites though are the frogs who spend the day waiting for the night’s action on the pond as I don’t have to spend too much time looking for them. There is always one boring one who will spend the day sitting on a lily pad but then there are the ones who sit on the lily flowers. Some spend the day on the flower stalk, probably convinced that they are invisible. The really fascinating ones sit inside the flowers or on the petals. During the peak sunlight hours the flowers are completely open and as the light starts fading the flowers close and the frog travels on the petal till he or she is completely enclosed by the flower.

I am no scientist and cannot really explain their choice of daytime resting spots. I do know that they do not like being disturbed and if you do so the frog will choose another spot to spend the next day. Maybe I should spend more time doing some real work…..

Beware Red Roses





Well its Valentine's Day and the florists are awash with red roses. They may look beautiful but they are contributing greatly to habitat damage in countries such as Kenya where vast flower plantations raise the flowers for the western markets.

In Kenya, flowers are the third largest export and the industry employs thousands of people.  Many of these flower plantations are located around the beautiful Lake Naivasha in the Rift Valley. The lake is an important wetland area rich in wildlife, but as flower production grows, so does the demand for water and this vitally important wetland is under threat.  The warning regarding the risk to the wetlands comes from ecologist  Dr David Harper at the University of Leicester who has spent 30 years researching these wetlands.

Many supermarkets sell these flowers with a fair trade label, which may mean that the workers get paid fair pay and treatment, but does not mean that the production of the flowers is environmentally friendly.


 Then these flowers are then shipped halfway across the world by air, so have a pretty hefty carbon tag too.

When you buy that bouquet of flowers check the label. Many come through Amsterdam, so a label saying the flowers are from Holland can mean they come from somewhere like Kenya. Far better is to go for something produced locally, or better still avoid buying the flowers altogether and donate the money to charity.

Global Food Crisis Looming


Is another global food crisis around the corner? The UN’s food and agriculture organization, FAO, has been warning that global food prices continue to rise and are a cause for concern. FAO’s cereal price index is now at its highest level since July 2008, but still 11% below the peak in April that year.

The world’s poor live mainly on cereals and rising prices have a direct effect on their livelihood.

Extreme weather has been responsible for shortfalls among many of the world’s major cereal producers: drought in Russia and Argentina, a heat wave and heavy rains in the U.S. and widespread flooding in Australia and Canada. And now China, the world’s largest wheat producer, is bracing itself for the worst drought in 200 years, at least in the province of Shandong.

Canada is the world’s third largest wheat exporter, after the U.S. and France, according to the International Grains Council. But production in 2010 was down 14% and extreme weather is by no means the only cause for the decline. A report just released by the Canadian Agri-Food Policy Institute concludes that Canada is in need of a significant overhaul of its agricultural policy in order to compete in global markets and help feed the world.

But it’s not just wheat production that’s the problem. The increasing demand on corn or maize (see photo) and soybeans for livestock feed and bio-fuels only adds to the pressure when grain is short for human consumption.

While the world has been warned that a major food crisis could develop this year, the good news is that global cereal stocks are higher than they were in 2007-08. But in a world struggling to recover from economic recession, the haves will be less able to share with the have-nots without running their deficits higher.

Penguins and Commercial Krill Fishing

These Chinstrap Penguins on Half Moon Island in the South Shetlands have stained the ground pink with their guano as their principal food is krill, a small shrimp. When humans first discovered the Antarctic they pillaged it and drove the whales and the seals to the very edge of extinction. Now with the arrival of commercial krill fishing are we about to see history repeating itself?

Antarctic Damage inevitable?


Adélie penguins on Paulet Island bathe in the summer sun. With the recent grounding of the cruise ship Polar Star in the Weddell Sea you have to ask is the possibility of environmetal damage from one of these ships getting closer?
Toursim in the Antarctic is on the up and fortunately the IAATO does a superb job in making sure that vists are carried out in a resopnsible manner.

TOSSERS AND JERKS


Thanks to the wonder of the internet I know what they call a person who throws litter out of a car window in the UK. They are called “tossers” and I am continually amazed that people still carry on tossing beer bottles and burning cigarette ends out of cars in South Africa too. Apart from the fundamental stupidity of the action accompanied by the litter and broken glass we also have the risk of bush fires. The prolonged drought (while the rest of the country is experiencing floods) is not helping either.

Over the weekend I was reminded of another type of person we have here. I do not know what they are called in the rest of the world so I have decided to label them “jerks.” I wanted to photograph a cute “penguins crossing the road” sign outside a penguin rehabilitation centre called the South African Marine Rehabilitation and Education Centre in Port Elizabeth. Someone had fired a metal dart similar to a hypodermic syringe needle into the sign using a blow pipe.

Apart from being just a stupid thing to do I am sure that someone like that would think nothing of shooting a dart into a random passing bird or person. The bird would eventually die and the person could lose an eye.

But we have people in South Africa that are even more stupid than this! There are road signs warning of animals crossing the roads all over South Africa. Kudu are especially dangerous at night as the car lights blind them and they try to leap over the car. They tend to hit the car at windscreen height and there are several deaths resulting from this every year.

Amazingly we have gun owners who shoot at these signs and try to hit the drawing of the animal. Obviously these are low intellect people who shouldn’t own firearms and to top it off they are lousy shots as they seldom hit the animal. When they miss the sign they could hit an innocent passer by and I presume that any animal they see is fair game. Maybe something as stupid as this is done when one is drunk?

I really do not like people as stupid as this and I do not know what to say about them except perhaps to use stronger words than tossers and jerks.

Why I hate gardening.......


I had a bad night last night. It all started perfectly fine when my left eye started burning a bit. I grumbled a bit and poured a glass of wine. It was not my turn to cook and I was preparing to enjoy the evening and take it very easy. No cricket to watch, just a bit of soccer, and little to distract me. Perfect!

And then my left eye started behaving badly. It started streaming tears and got a little painful. Luckily I have an expired first aid kit which has some eye drops and I dripped some drops and went back to my couch. This was when my eye became more irritating than Manchester United and their supporters. It hurt when open and also hurt when closed and was time for drastic measures like a deep hot bath and aspirin. This did not work either.

One of the things I should never do when in pain is look in a medical reference book or google the complaint. By then my eye was streaming tears to the extent that I thought of drinking water to prevent dehydration. Google did not help as I was not prepared to let someone urinate in my eye (apparently good for Spitting Cobras) and irrigating the eye with water did nothing. The only thing I had done that afternoon was a little gardening and cut down a Euphorbia mauritanica. The flower books don’t say much apart from “succulent shrub, up to 1m. Flowers mustard coloured in terminal clusters. Dry hillsides.”* It did not mention the toxic nature of the white sticky sap but it was something I had been warned about. I must have had a little sap on my hand and wiped my brow. Sweat must have carried the sap to my eye.

I also remembered an old first aid tip from long ago and bathed my eye in milk and the relief was almost instantaneous.*

Avoid gardening and rather do something healthy running a marathon or bungee jumping.
