Tropical timber derived from old-growth tropical forests which is widely recognised as a renewable natural resource, is selectively logged worldwide at an unparalleled scale.
But research from the University of East Anglia reveals that these sources of timber are far from sustainable or entirely environmentally friendly.
A study published today in PLoS ONE reveals that once prime tropical hardwoods – such as Brazilian cedars, ipe (Brazilian walnut), and rosewood – have been logged, they do not grow back to commercial levels and are at risk from disappearing altogether.
Lead author Dr Vanessa Richardson, from UEA’s School of Environmental Sciences, said: “Slow growing and commercially valuable species of all kinds have been overexploited over the course of human history – just look at the whaling industry or fisheries.
“Yet many tropical timber species are still thought of as a renewable resource. We are only beginning to see over-exploitation parallels in tree species.
Our research shows that many high-value timber species are logged until their populations collapse altogether.
The research team studied 824 forest sites scattered throughout the 124 million hectare Brazilian state of Pará. They analysed data from legal logging operations that harvested approximately 17.3 million cubic meters of timber across 314 tree species in the state of Pará.
Timber harvests in Pará equate to almost half of all native forest roundlog production in Brazilian Amazonia – the largest old-growth tropical timber reserve controlled by any country. Brazil accounts for 85 per cent of all native neotropical forest roundlog production. They found that loggers can no longer depend on areas where high-value species were formerly abundant, to fetch high economic returns.
This means that logging operations are continuously forced to extract timber trees from new areas of unlogged primary forests.
Prof Carlos Peres, an author on the study from UEA’s School of Environmental Sciences, said: “Our analysis shows that even so-called ‘reduced-impact logging’ in tropical forests can rarely be defined as sustainable in terms of forest composition and dynamics in the aftermath of logging – never mind the greater susceptibility of logged forests to catastrophic fires.
“Environmental licensing and market certification of logging concessions need to take this into account, and review minimum preconditions in terms of volumetric quotas of roundlogs harvested per species and regeneration standards over multi-decade logging cycles.”
- After selective logging, there is no evidence that the composition of timber species and total forest value recovers beyond the first-cut. This suggests that the most commercially-valuable timber species become predictably rare or economically extinct in old logging frontiers.
- Only recent logging operations, which are furthest away from heavy-traffic roads, are the most selective, concentrating gross revenues on a few high-value species.
- Managing yields of selectively-logged forests is crucial for the long-term integrity of forest biodiversity and financial viability of local industries.
Dr Richardson added: “Previous studies in Asian markets suggest that current commercial agreements could lead to ‘peak timber’ and then widespread economic extinctions across other tropical regions.
“Our study adds a Neotropical body of evidence to support this. We can already see a market shift, in which loggers in old depleted logging Amazonian frontiers are forced to depend on fast growing, soft-wood timber species.”
‘Temporal decay in timber species composition and value in Amazonian logging concessions’ is published in the journal PLOS ONE on July 13, 2016.

4 Common Items That Can be Reused Again and Again
As a society we are getting much better at taking our obligations to the world and environment around us more seriously. This is undoubtedly a good thing! The effects of climate change are beginning to manifest across the world, and this is turning the issue from an abstract threat into a very real danger. Trying to introduce some greener, more eco-friendly practices into your life isn’t just a great way of doing something beneficial for society and the world around you. It is a wonderful way of engaging positively with the world and carries with it numerous psychological benefits.
Being a greener, more ecologically friendly person doesn’t require any dramatic life changes. Breaking or making a few small habits is all it takes to make your life a greener one. In this article we look at one of the easiest, yet most effective green practices to get into: reusing everyday items.
Jars and Containers
Glass and metal are widely recycled, and recycling is a good thing! However, consider whether any containers you buy, whether it’s a tub of ice cream or a jar of coffee, can be washed out and reused for something else. Mason jars, for example, can be used to store homemade pasta sauce and can be washed for future use. Once you start thinking about it, you will find endless opportunities to reuse your old containers.
An ice-cold soda is a wonderful treat on a hot day, but buying soda can get expensive, and the manufacturing and distribution of the drinks themselves isn’t great for the environment. However, by holding on to your old soda bottles and repurposing them as water bottles, you can save money on drinks, or use them to measure out water for your garden.
Most of the time groceries come in paper bags, which are better for the environment than the plastic alternatives, but they are less durable and thus harder to reuse. Whenever the store places your items in a plastic bag, hang onto it so you can reuse the bags again. If you want to take it one step further, consider looking into buying some personalized recycled bags. These bags are designed to last for a long time and are made of recycled materials. They look striking and unique, they’ll turn heads, and maybe even attitudes!
If you’re a keen gardener, then you will already probably know how to reseed your plants in order to ensure a fresh crop after each plant’s lifecycle. If you have space in your garden, or haven’t yet tried your hand at gardening, then consider planting a small vegetable plot. Growing your own veggies means that you’ll be helping to cut back on the emissions generated by their transport and production. The best part about growing your own food in this way is that, by harvesting properly and saving the seeds, you can be set up with fresh vegetables for life!
Reusing and recycling common household items is an easy way to make your world a little bit greener. Once you start looking for these opportunities you’ll realize that they’re everywhere!
These 5 Green Office Mistakes Are Costing You Money
The sudden interest in green business is very encouraging. According to recent reports, 42% of all companies have rated sustainability as an important element of their business. Unfortunately, the focus on sustainability will only last if companies can find ways to use it to boost their ROI.
Many businesses get so caught up in being socially conscious that they hope the financial aspect of it takes care of itself. The good news is that there are plenty of ways to go green and boost your net income at the same time.
Here are some important mistakes that you will want to avoid.
Only implementing sustainability on micro-scale
The biggest reason that brands are going green is to improve their optics with their customers. Too many businesses are making very minor changes, such as processing paperwork online and calling themselves green.
Customers have become wary of these types of companies. If you want to earn their business, you are going to need to go all the way. Bring in a green business consultant and make every feasible change to demonstrate that you are a green organization from top to bottom.
Not prioritizing investments by long-term ROI
It isn’t realistic to build an entirely green organization overnight. You will need to allocate your capital wisely.
Before investing in any green assets or services, you should always conduct a long-term cost benefit analysis. The initial investment for some green services may be over $20,000. If they don’t shave your cost by at least $3,000 a year, they probably aren’t worth the investment.
Determine which green investments will have the best pay off over the next 10 years. Make these investments before anything else. Then compare your options within each of those categories.
Implementing green changes without a plan
Effective, long-term planning is the key to business success. This principle needs to be applied to green organizations as well.
Before implementing a green strategy, you must answer the following questions:
- How will I communicate my green business philosophy to my customers?
- How will running a green business affect my revenue stream?
- How will adopting green business strategies change my monthly expenses? Will they increase or decrease them?
- How will my company finance green upgrades and other investments?
The biggest mistake that too many green businesses make is being overly optimistic with these forecasts. Take the time to collect objective data and make your decisions accordingly. This will help you run a much more profitable green business.
Not considering the benefits of green printing
Too many companies believe that going paperless is the only way to run a green organization. Unfortunately, going 100% paperless it’s not feasible for most companies.
Rather than aim for an unrealistic goal, consider the option of using a more environmentally friendly printer. It won’t be perfect, but it will be better than the alternative.
According to experts from Doranix, environmental printers have several benefits:
- They can process paper that has been completely recycled.
- They consume less energy than traditional printers.
- They use ink that is more environmentally friendly.
You want to take a look at different green printers and compare them. You’ll find that some will meet your needs as a green business.
Poorly communicating your green business strategy to customers
Brand positioning doesn’t happen on its own. If you want to run a successful green business, you must communicate your message to customers as clearly as possible. You must also avoid the appearance that you are patronizing them.
The best approach is to be clear when you were first making the change. I’ll make an announcement about your company‘s commitment to sustainability.
You also want to reinforce this message overtime by using green labels on all of your products. You don’t have to be blatant with your messaging at this stage. Simply provide a small, daily reminder on your products and invoices.
Finally, it is a good idea to participate in green business seminars and other events. If your community has a local Green Chamber of Commerce, you should consider joining as well.
