The World Lost an Oklahoma-Sized Area of Forest In 2013, Satellite Data Show 143

merbs writes Oklahoma spans an area in the American South that stretches across almost 70,000 square miles. That's almost exactly the same area of global forest cover that was lost in a single year. High resolution maps from Global Forest Watch, tapping new data from a partnership between the University of Maryland and Google, show that 18 million hectares (69,500 square miles) of tree cover were lost from wildfires, deforestation, and development the year before last. The maps were created by synthesizing 400,000 satellite images collected by NASA's Landsat mission.

  • All of those losses of forest are very different:

    * After wildfires, trees naturally re-grow.

    * Some deforestation is replaced with new trees, but not all.

    * After development, trees are usually planted - sometimes where there used to be no trees. What is the net gain/loss of trees across ALL development, not just development taking place in a forest...

    To say nothing of; what is the natural level of variation in forest year to year? From wildfires alone you would think there would be a substantial amount.

      "The World Resource Institute, which coordinates Global Forest Watch, notes that the loss is both of the permanent, human-driven varietyâ"razing for agriculture and developmentâ"and the cyclical; from fires, logging, harvesting, and natural tree death. In the case of the latter, forests can take decades to be restored. In the former, they are gone for good"

        So yes, I did read that, which it was exactly what led me to wonder what the breakout was of each of those things. If it's primarily natural cyclical loss that will be restored why should I freak out again?

        • So yes, I did read that, which it was exactly what led me to wonder what the breakout was of each of those things. If it's primarily natural cyclical loss that will be restored why should I freak out again?

          And natural cyclical loss may not be the primary cause currently in the TFA. However, the TFA goes further and states that natural cyclical loss could become a primary cause if this deforestation process with the help of humans keeps going on.

          From TFA

          Scientists expect wildfires to become more frequent as warmer temperatures afflict forested regions.

          In other words, yes we should concern about deforestation on natural cyclical loss even though it is currently not the primary cause if less forest causes warmer temperature.

    • According to TFA, most of the loss was to natural wildfires, especially in Canada and Russia. But TFA doesn't say what a "normal" amount of wildfires is, and whether 2013 had more or less than normal, or even whether the total amount of deforestation is going up, or down. Factoids should have context. This a a good example of bad journalism.

      • To be honest here in Canada we need massive wildfires to clean up the pine beetle problem. The wood can be used, usually in chipboard or paper products as long as the tree isn't fully rotten among other problems. When I was driving out through western canada a couple of years back it was a serious problem, and if you want to see what happens when a wildfire plus pine beetle infestation can do to an area, look at the slave lake fire. The fire was deliberately set, but the forest in the area is infested with pine beetles which have caused massive die offs with the trees, basically making it a perfect situation.

        Anyway, once a place is burned out, harvested, and so on we plant new trees there anyway. The forestry industry here is amazingly good at creating an entire harvest, burn, plant cycle. Not forgetting that we have laws on the books that companies that harvest(anything whether it be trees, oil, oilsands, coal, etc) have to by law set aside funds for restoration. The government oversees the funds to ensure that enough is being put aside.

      They will eventually, but in the amount of time it takes for them to regrow, drastic environmental impacts may happen which destroy their habitat and make it no longer a fit for that particular plant. A simple example would be mountain flooding after a wildfire. When conifers burn, they will leave a sheet of wax on top of the dirt. When snow runoff season begins (or there are heavy rains, as seen in Colorado in 2013) the ground is not as good at sponging up the moisture and releasing it slowly down-river ov

        Forests are very optimized to handle fires, because fire is a natural occurrence that forests must deal with. Over time, some forests even require fire to thrive (like bristlecone pines which use the heat from fires to activate seeds in cones).

        The main problem with fires is if there has (ironically) been too much prevention, then there is a lot of dead undergrowth and the fire burns hotter than normal.

        So, again, which is it? Were these fires that have been monitored normal forest fires, that the landscape will deal with? Or were they more harmful for some reason?

        Can you begin to see the feedback loop?

        Again, the feedback loop is part of a natural process.

        I'm not sure I understand their definition of "deforestation"

        Great question also. Does it include pines killed from pine beetles for example?

          • Natural isn't always good. It is not artificial. A natural process typically has been going on for a long time.

            Therefore, if a natural process permanently destroys forests, we'd have to wonder why we still have forests. It would seem that the natural fire cycle keeps forests very roughly stable, over time. Therefore, it's useful to know how much deforestation is caused by human (and irreversible) causes and how much by natural (and presumably reversible) causes.

      Some of the first laws on the books in California were prohibition of setting fires, for use against natives. They set controlled burns every year which kept the understory clear and the forests healthy. But other natives set fires to clear land for Bison. The landscape of pre-America America was very much deliberately created by peoples who had, after all, some 20,000 years to transform the continent.

    I don't understand how you can label Canada as losing all that forestation without mentioning MPB and other outbreaks which are on the rise.

    Do they not realize that many of those forest fires wouldn't have happened outbreaks were less severe? This is ignoring the wildfire suppression that happened in the first place which contributed to the destruction being seen in the last few years.

    Interesting to think that suppressing wildfires might actually contribute to climate change.

  • Oklahoma was a tall grass prairie 150 years ago, with very few trees. Now there is considerable forestation. Much of this is due to human activity (for example, tree seeds being spread through cattle poop when being driven to market). Should we cut them all down and plant grass?

      Pink only indicates change. Forests can change without human intervention you know.

      • I don't think they have changed though... I mean, the forest is on average as dense as ever. A given tree is going to fall over now and then... but that's normal. The mushrooms go nuts on it... turn the tree to a rich mulch... and lots of saplings grow up in its place. That's a healthy forest.

    • Agreed, Looking at the map around where I live. Almost all the pink is the result of fires the last few years. And it takes a while but those trees are growing back. Intentional, accidental or natural wildland fires, they are all recovering nicely, the new growth thriving on the ash enriched soils. It will be decades before the end stage forests that burned return to that point but the natural process is proceeding nicely.

      It's probably not because of the increased CO2, because most plants can't make use of much more CO2 than they get already. In order to do so, they'd have to receive more energy from sunlight, so that they could do more photosynthesis — but most plants have evolved to make use of a certain range of insolation, and they don't function correctly or even die if they get much more than they're used to. CO2 enrichment is a thing, but it doesn't work on all plants, and it's coupled with artificial lighting.

        That's the long way of putting it, but yes. If the rainfall patterns stay the same as they are now vegetation will continue to grow in those same areas and the carbon will (on average) remain out of circulation. If the rainfall patterns continue to change the new vegetation in the affected areas won't get enough water and will die/not regrow in the new season and the carbon will quickly return to the environment. Like i said, the not so good side of things.
