More weeds in the yard!

Since we have been in our place nearly a year it was time to tackle some of the larger tasks we have been putting off. Chainsaw in hand, a number of umbrella trees and African Tulip trees were in our sights. These two species are weeds here in south-east Queensland. They are quickly spread throughout the environment by our lovely native birds, which eat their seeds and fly elsewhere poop out the seed and voila a new tree sprouts! Basically, these species have the ability to out-compete our native tree species, through quick establishment, prolific seeders and lots of helpful native birds assisting their movement. 

We removed three semi-mature African tulip trees and about five umbrella trees from the bottom of one of our paddocks. All we did was chop them off at the base and pile the top half of these trees in a big pile (will chip later). We will then monitor these stumps for re-growth and if required undertake some additional treatment (maybe salt).

Here are some piccies of these two offending weeds.

Umbrella Tree

In addition, to chain-sawing the trees out, I choose to remove a small patch (about 5m x 1.5m) of broad-leaf paspalum. This is a shade-tolerant, non-native, hardy grass species, which out-competes many of our native grasses. I employed the assistance of a fork and just loosened the soil around the base of each individual outcrop and removed them to the domestic waste bin once out of the ground. I did this action about three weeks ago and so far no new outcrops of this grass have sprung up in the area of 'treatment'.

Hope these treatment options hold and with my revegetation money I will look to establish a bit of a native cover crop/midstorey to replace these weed species and provide some additional protection for my overstorey eucalypts.

Biodiversity, life as we know it?

I am an ecologist (a person that studies native plants & animals in their local context and within the "living web of life") by trade and in recent months I have become disillusioned with the possible longevity of many of the species that occur naturally within my local urbanised environment and broadly in the Australian landscape.

The thirst of the current Australian population to satisfy their personal needs and wants sees little space for the appreciation of the natural environment and in turn the right for all species to inhabit this planet with us. It seems that if a species, no matter its relative importance, gets in the way of "progress", it is justifiable to decimate these individuals at the location of interest.

With the ongoing development and increasing global population, I see no stop to this progression or mantra. The human focus on the environment and how we will survive climate change, we will survive sea level rise, we will survive the economic downturn, shows little regard or consideration for other people or other species on the planet.

My hope is that all of us remember our childhoods and reflect on the enjoyment we got from playing in the mud, along with the slugs, bugs and other creepy crawlies. For those in a more country setting, enjoying the wallabies or kangaroos grazing in the paddocks as we attempted to surprise them in an early morning fog. Or just remember that all creatures great and small have a right to live on this planet just as much as you and I and we should have some consideration for their welfare as we approach these tough times.


Sure we want all the current seven billion people to survive on this planet and have the capacity to live with some prosperity. But we should also have the capability of bringing most of the species that live on this planet along with us. Perhaps some food for thought?

Deepwater Horizon...nearly two years on!


(Source: Planet for Life)

It is nearly the two year anniversary of the biggest oil spill in the Gulf of Mexico caused by a drilling rig called the Deepwater Horizon. I can't believe that it has been two years, but the effects of this event are still being felt in the surrounding marine and terrestrial environments.

The National Geographic has an interesting article on their website by Brian Handwerk, describing some of the activities that are still being carried out on the beaches and how much effort is still being put into the 'clean-up' activities. It is interesting to also note that it still seems there are significant questions about whether the contaminants that remain within the environment are reason for concern and what health impacts they may pose.

I'm sure there is much research and learnings being generated out of this horrific event, but I don't know if I would like to be living in the experiment. Pin It

Take 3 campaign

The Take 3 campaign was started in 2009 by Tim Silverwood. The idea behind the campaign is the reduction of plastic and general pollution in our waterways and ocean. The premise is that when you visit your nearest waterway or beach, you take three pieces of rubbish away with you and put them in the bin.

Why?

As you're aware from one of my previous posts there is a giant garbage patch in the middle of the Pacific Ocean. Apparently the scientific community believes that it is impossible to actually eradicate this plastic pollution from the ocean. But, further plastics can be prevented from entering the waterway and becoming part of this floating garbage soup!

So, maybe you could adopt this as a something you do the next time you visit your nearest creek, waterway, beach or coastal region and get a warm glow on the inside for making a difference to your local and global environment. Pin It

Call for flying fox cull....aargh!

On 6 January 2012, the Courier Mail reported that MP Bob Katter had suggested he would introduce legislation to the Queensland Parliament seeking that landholders gain the right to control "deadly" animals from their backyards, including flying foxes because of the threat of hendra virus. Can you believe it?

I wrote about hendra virus and flying-foxes a little while back and in this you can see the risks associated with the presence of flying foxes are not significant. It astonishes me the lack of understanding people have and for people in the public eye spreading such crap, it is unforgivable!

Living with nature is part of our world and should be celebrated not demonised. Be aware of how to live with these creatures and you will be surprised at the richness of your life and the type of interactions and experiences you will have. Enrich your lives with these creatures, let's not try and make a "moonscape" of suburbia.

If such legislation did ever get up (doubt it with the current political climate, probably just trying to get some media attention) I'm sure the hospitals and health practitioners would request that such legislation be overturned due to the significant increase in the number of people they had to treat through snake bites and other mis-adventures when landholders attempted to "control" these animals in their backyard.

What is Palm Oil?

In recent years I have heard bits and pieces about palm oil and how it is used in many, many products that we consume (grocery and cosmetic items) and how it is impacting on precious tropical forests in south-east Asia, particularly orang-utan habitat. Other than these things, I don't know a lot more about palm oil or its issues.

I was reminded of this issue this morning when reading the finished box of soap as I took it from the bathroom and to the recycling bin. I think the brand is "Country Life" and it advertises itself as Australia made and owned and Palm Oil Free. You will also find in smaller print it is made from locally and imported ingredients (as most things do).

Anyway, I thought I should have a look into what "palm oil" is. WWF has an informative webpage that describes palm oil as being derived from the "fruit of the oil palm tree", which comes from two main oil palm trees (African Oil Palm and American Oil Palm). Further information about palm oil and its uses from WWF site include that

"the palm fruit yields two distinct oils - palm oil and palm kernel oil. Palm oil is extracted from the pulp of the fruit, is edible and used in food. Palm kernel oil is extracted from the seed of the fruit and is used mainly in the manufacture of cosmetics."

The growing of oil palm trees seems to be quite widespread around the tropics, with palm oil plantations in our region being focused in Malayasia, Indonesia and Papua New Guinea. Furthermore, these plantations are apparently often associated with illegal or unsustainable deforestation activities (although I will have to investigate this further).

Once again, the consciousness of the consumer can make a difference to such matters and certainly impact on businesses and activities outside our national boundaries. We can achieve this just by making informed choices about the products we choose to buy.

As the GreenPalm.org website states that if we just stop "our" consumption of palm oil, it is likely that the product will then just be purchased by another "user". But, if appropriate assistance (in the way of education and trade support, for example) can be provided to primary producers in these regions (many countries being third world nations) there is the possibility they will be able to modify their  businesses towards sustainable practices. There may also be better planning (through assistance) for new plantations, thereby reducing or preventing deforestation of these important areas.

My understanding is that the GreenPalm group is supporting such actions for this industry through the development of a certificate trading program for palm oil, which includes the labelling of products containing sustainably produced palm oil. WWF and a number of other interested groups also seem to tackling the issues and providing education to consumers and producers, as well as developing standards for responsible palm oil plantations, through the Roundtable on Sustainable Palm Oil.

Again, it can come down to being conscious of your choices, choose products that have sustainably produced palm oil or no palm oil (where there is sustainable product alternatives) and try to find out where the "imported ingredients" come from and generally make informed decisions.  

If you'd like to know more details of what countries and brands are using palm oil, as well as their commitment to utilise sustainable palm oil sources in the future, the WWF has developed the Palm Oil Buyers' Scorecard 2011: Measuring the Progress of Palm Oil Buyers.

"Happy" World Food Day

The 16th October 2011 is World Food Day (celebrated by the Food and Agriculture Organisation of the United Nations).  This year's theme being "Food Prices - from crisis to stability". This theme reflects the precarious nature of food availability and how fluctuations in the price can significantly people in third world countries.

The objectives of this day are to:

  • encourage attention to agricultural food production and to simulate national, bilateral, multilaterial and non-governmental efforts to this end; 
  • encourage economic and technical cooperation among developing countries;
  • encourage the participation of rural people, particularly women and the least privileged categories, in decisions and activities influencing their living conditions;
  • heighten public awareness of the problem of hunger in the world; 
  • promote the transfer of technologies to the developing world; and
  • strength international and national solidarity in the struggle against hunger, malnutrition and poverty and draw attention to achievements in food and agricultural development.

The future for our species?

I am amazed at how many people are turning their back on the science of climate change. Whether the current situation is man-made or natural the climate will eventually change....the earth's history shows us this and you would think as a selfish species (and we all know we are) we would look to be protecting our existence on this planet as best we can. I can't believe people are so blind-sighted by their current passion, interest, lifestyle, etc, etc that the idea of enabling our species to persist on earth is such a foreign concept. That is really what everything boils down to. The issue isn't whether you believe climate change will wipe out the human species or another large asteroid or a volcanic explosion, the bigger picture is the long-term survival of our species.

So if you really want to make a difference for your kids, your kids' kids and so on, think about how much of a difference you can make for future generations, be that in the form of supporting a carbon tax, adding some solar panels to your roof or whatever measure that you think make a difference. I know such pragmatism doesn't appeal to all people, but you would think that it would appeal to the majority of people since we keep breeding and wanting more and more for our children.    

There are so many things that people believe in that can't be perceived by science or visualised and yet people continue to show their faith in these. Why can't people therefore believe the proven science of human-induced climate change which can clearly be demonstrated and shown to be future of planet earth if we remain on the current track we are following. Do your bit to make a difference and ensure the long-term survival of our species, including our children's children! Pin It

Desertification

What is desertification? I have heard the term but really don't know what it means. From my reading it is where dryland used for agriculture and other purposes loses its economic and biological productivity and usually results from climatic variability (change) or unsustainable human practices.

Some of you might now be wondering...'what are drylands'? Well, these are lands that can be productive with limited input from irrigation or natural precipitation. This does not however mean that they are resilient and can remain productive with no or limited rain, it means that they are adapted to a particular level of natural precipitation or human intervention and when this changes they are no longer productive.

I have heard this term mostly associated with Africa and I would like to learn more about the causes of this situation both in Africa and in other locations. Pin It

Solar rights

I have just been reading an old volume of the ABC's Organic Gardening magazine. The editorial was discussing rights to access solar energy. I really hadn't thought about this prior to reading this. It is however something that perhaps we all need to consider.

The article was discussing the significant increase in the number of households that were installing solar panels. I too have considered getting some, with my parents actually investing in a small number of solar panels that's cost were fairly well covered through the governments' current rebate programs. But the point the article was making was that your rights to access solar energy is no guaranteed under any planning law in Australia at present. That is, if your neighbour decides to construct a structure or building that ends up shading your solar panels and you can no longer generate solar power, there are currently no laws to support your rights to the previously available solar energy. So potentially all your financial investment becomes worthless and you may potentially need to re-invest in less sustainable energy options.

I thought this was unbelievable. I am hoping this is just a matter of legislation catching up with reality. Once governments, particularly local governments, becoming aware of this issue, particularly with the increasing presence of these panels in the suburbs, hopefully they have the balls to amend their planning legislation/policy to support the proactive person in the attempt to become more environmentally sustainable rather than some of the typically short-sighted decisions that are made in this development forum.

Something to consider if you're considering installing solar panels or perhaps encourage you to campaign your local government to protect your solar rights. Pin It

Cats......do my head in!

Today I was outside with my toddler and I heard something a bit out of the ordinary outside from front gates. It was a bird making a strange noise. My brain finally kicked into geared, opened the gate, just to see the next-door neighbour's cat with a figbird in its mouth! Arrrrrgggghhh!

I ran out of the gate and told the cat to drop it. The cat just looked disdainfully at me and jumped over the neighbour's fence into their backyard. No doubting the cat certainly had a tasty meal!

Cats whether they are loved pets or ferals running the neighbourhood are often responsible for the death of much of our native wildlife, particularly in the suburbs. If you have a cat:

  • make sure it is kept inside at night;
  • has a bell around its neck;
  • if you can afford it invest in a cat run, so your friendly moggy is keep completely separate from the native wildlife that makes our suburbs a little more friendly.

Albatross - I love them!

I love albatross! They are so majestic and the idea of wandering the oceans, soaring over the waves and just scooting around the planet is just so appealing.

These birds are however, highly threatened. Mainly through longline and trawler fishing, but they are also threatened at their nesting habitats. There are many difficulties in trying to conserve these oceanic species. One of difficulties being that many of these species occur across a number of nation's national boundaries. In such situations there will always be differences in government opinion towards conservation and albatross specifically; the amount of financial support for research and conservation and general public interest in conservation.

Here in Australia we do support albatross conservation (broadly) and the government has a number of policies in an attempt to boost albatross numbers. The fishing industry also seems to be doing its part, but whether it is doing all it can I'm not sure.

Just thought I would bring your attention to this issue, as these creatures are probably my favourite in the world! Pin It
