This week we are celebrating World Environment Day (today!) AND World Oceans Day (June 8).

The theme for both in 2018 is “Beat Plastic Pollution”. If you can’t reuse it, refuse it!

At Bonorong, we see firsthand how plastic causes injury and illness in our wildlife. The global numbers speak for themselves:

Up to 5 trillion plastic bags are used each year
13 million tonnes of plastic enter the ocean each year (around a truckload every minute)
1 million plastic bottles are bought every minute
100,000 marine mammals and 1 million seabirds are killed by plastics each year
90% of bottled water and 83% of tap water has been found to contain plastic particles
50% of consumer plastics are designed to be single-use
In the next 10-15 years global plastic production is projected to nearly double
By 2050, there will be more plastic in the oceans than fish

So, what can you do about it?

Reduce single-use plastics. They’re everywhere… Bottled water and soft drinks! Plastic bags! Straws and cutlery! Balloons! Many of these can substituted for a multi-use option or avoided altogether. If this happens enough, retailers will get the message and find alternatives.
Avoid products that contain microplastics, such as many cosmetic products.
Pick up rubbish from the beach when you visit and save it being washed back out by the tide.
Join the global #BeatPlasticPollution game of tag. Invite friends and colleagues to take a selfie with their canvas shopping bag, metal straw or any other reusable product and tag five friends, telling them to do the same. The person tagged should post a photo with their reusable item within 24 hours.
Carry out a plastic audit of your home or business to see where you can reduce your plastic usage. Set targets and make a plan to achieve them.
If you’re a teacher, lessons plans can be found on the World Environment Day website to teach your students about the issue.

Today, millions of people in over 100 countries will be celebrating the natural environment and taking action to reduce their impact on the planet we all call home. What will you do?

Brrrrrr! It’s starting to get cold! As the winter chill sets in, many of us dream of a warm fire to curl up in front of. In fact, Tasmanians are the greatest consumers of firewood in Australia, burning almost 6 tonnes each year!

However, many of the trees felled for our fires provide homes to native species. This little ringtail possum and her joey were brought to Bonorong after the tree they were in was cut down. Sadly, mumma poss did not survive her injuries and joey will require long term support from a wildlife carer.

At least 29 native Tasmanian bird species depend on hollows to nest in. Four of these are listed as threatened, including the critically endangered orange-bellied parrot, the endangered swift parrot and forty-spotted pardalote, and the vulnerable masked owl. Native mammal species, such as possums and bats, also rely on hollows to live in.

Once fallen, trees continue to provide important hiding places and den sites for species such as echidnas, Tasmanian devils, quolls and lizards. Less ‘obvious’ species such as invertebrates, fungi, mosses, lichen, and micro-organisms (bacteria, small fungi, and algae) also rely on fallen trees for habitat. Further, fallen trees play essential roles in the recycling of forest nutrients and provide protection for numerous species during forest fires.

In Tasmania, most firewood is collected by the user or by small non-commercial suppliers. Only a small proportion (approximately 17.8%) is sourced from forests managed for wood production and a similarly small number of firewood merchants seek permits for their work. The lack of regulation surrounding firewood collection means that the impact on wildlife each year is high.

Further issues can include:

The spread of weeds, diseases and pathogens from one location to another by dirt on boots, clothing and vehicles.
Danger to collectors posed by the use of chainsaws or overloaded vehicles.
Environmental degradation such as increased sedimentation in streams, excessive rutting of roads and tracks, erosion, fuel spills, and escaped fires from camp fires.
Illegal rubbish dumping.
Property damage to fences, gates and roads.
Air pollution from burning poor quality (green) wood.

We all need to stay warm in winter but by keeping these simple tips in mind when heading out to collect firewood, we can reduce our impact on wildlife:

When felling your own wood:

Fell living trees and leave them to dry for use the following year.
Avoid bigger trees and logs that may have hollows (or that may form hollows if left to decay). Look for smaller trees and branches instead.
Ask permission of the land manager to collect waste wood from recently harvested forestry coupes.

When buying wood:

Try to purchase wood from Firewood Association of Australia (FAA) accredited sellers or from a reputable wood yard. This will also give a point of contact if you have complaints about the load size or quality.
Ask where your firewood has been sourced from. If the vendor cannot tell you where the wood has come from, look elsewhere.
If available, purchase timber from plantations rather than from native forests or woodlands.
Ensure that your firewood has not been collected from areas listed as critical habitat for endangered species.

And of course, if you do find an injured or orphaned animal call Bonorong Wildlife Rescue 24/7 on 0447 ANI MAL.

Happy World Environment Day!

Keeping our woodfires wildlife-friendly this winter...
