Sustainable forestry: It’s more than just planting trees Forestry and protected fish habitat are completely compatible. Washington Forest Protection Association The forestry industry has come a long way since the mid-19th century. Working forests are now an important part of our landscape because they support the economy and provide habitat and protect clean water while the trees grow for 40-60 years before the next harvest cycle. When managed responsibly, sustainable forestry can meet a wide range of needs for people and the planet forever.“Sustainable forestry involves a renewable cycle of harvesting what we plant,” says Mark Doumit, Washington Forest Protection Association. “It means caring for our forest resources, providing fish and wildlife habitat, and protecting clean air and water. At the same time, we provide jobs for rural economies and renewable wood products.”The first American Tree Farm was designated in 1941, near Montesano, Washington, to promote a renewable cycle of sustainable forestry. Today, nearly all harvested logs are from second- or third-growth forest.Protecting Washington’s History The Pacific Northwest is home to the oldest forests in America. Washington has about one-third, or nearly 3 million acres, of these old-growth forests over 160 years in age – that’s equal to more than three times the area of the Olympic National Park. Nearly all of these forests lie within federal protected areas.Keeping Washington evergreenUnlimited Digital Access. $1 for 4 weeks.Washington’s forests are an integral part of the state’s character, covering one-half of our land area, mostly west of the Cascade mountain range. Close to two-thirds of that forestland is managed by state, federal and tribal governments; one-third is privately owned.Privately owned forests are supplying close to 70 percent of the wood harvested in Washington each year, making us the second-largest lumber producer in the U.S. It is because of the economic health of the forest industry – Washington’s third-largest manufacturing sector – that working forests provide a host of environmental services in addition to wood products, such as, clean water, wildlife habitat, carbon sequestration.A renewable resource Each year forest landowners in Washington plant an average of 52 million tree seedlings in areas that have been harvested. On average, that’s three seedlings planted by hand for every one tree harvested. Replanting is just part of the day-to-day effort in working forests, a sustainable practice that ensures after harvest a new forest begins to grow quickly, usually within 12 to 18 months.Nearly all of these seedlings come from local tree nurseries and are grown from seeds collected from cones within the same region or “seed zone.” The first seed zone maps were published in 1966. The use of this evolving information enables landowners to replant trees that are best adapted to their site, limiting damage from climate and pests and maintaining locally adapted gene pools.Stewards of Washington’s forests WFPA’s member companies are using science-based research and collaboration to keep the trees as well as the wildlife habitat of their private forests healthy. From compliance with federal and state laws to building timber harvest plans that minimize environmental impact, private forest landowners are committed to being stewards for the water, soil and wildlife of working forests.Forest practices are the result of more than a century of experience from learning by doing and scientific study of the effects of forest management on the natural environment.Adaptive management and science are used to measure what is actuallyhappening to the environment during forestry operations. The results ensure that forestry operations are conducted in a way that restores salmon habitat and protects water quality by leaving buffers of trees alongside streams, removing and replacing fish-blocking culverts, and upgrading roads to the latest standards. The goal of adaptive management is to make changes in forest practices, based on scientific information to ensure that forestry and fish-habitat are compatible.The Washington Forest Protection Association is a trade association representing private forest landowners in Washington State. Members are large and small companies, individuals and families who grow, harvest and re-grow trees on about 4 million acres.Washington Forest Protection Association

There’s a compelling reason scientists think we’ve never found aliens and it suggests humans are already in the process of going extinctKevin LoriaView photosInternational Space StationUnchecked climate change will eventually lead to widespread devastation on Earth.Rising seas will inundate coastal cities like Miami, searing heat will increase human mortality, and acidic oceans will become inhospitable to fish and coral, leaving behind little but rubbery masses of jellyfish.These consequences of human activity could be the thing that prevents our civilization from advancing much further. In a particularly extreme scenario, it could even wind up wiping us from the face of the Earth.That may sound unlikely, but it’s the answer some scientists are giving to a perplexing question: Why haven’t we encountered intelligent alien life?The Fermi ParadoxWe live in a galaxy with between 100 billion and 400 billion stars, each potentially surrounded by planets. Until recently we thought there were around 200 billion such galaxies in our observable universe, each containing hundreds of billions of stars and trillions of planets. New NASA research indicates there are probably at least 10 times as many as we thought.Even if habitable planets are rare and if life is exceedingly unlikely to arise, those mind boggling numbers suggest there should still be other intelligent life somewhere in the universe. If just 0.1% of potentially habitable planets in our own galaxy harbored life, there would still be a million planets with life on them.So, as Nobel-prize winning physicist Enrico Fermi famously asked of our alien neighbors, „Where are they?”View photoskaren nyberg female astronaut international space station iss cupola windows expedition 37 nasaWhy haven’t we heard from aliens or found any evidence of their existence? That question is known as the Fermi paradox, and there are a number of potential answers to it (most are fairly disconcerting).One hypothesis is that before intelligent life manages to spread beyond its original planet to other nearby planets, it runs into a sort of „Great Filter.”As philosopher Nick Bostrom explains it, this idea suggests there are several „evolutionary transitions or steps” that life on an Earth-like planet has to achieve before it can communicate with civilizations in other star systems. But some sort of obstacle or barrier may make it impossible for an intelligent species like ours to get through all those steps. That would explain why we haven’t heard from or seen any other life.Bostrom writes:You start with billions and billions of potential germination points for life, and you end up with a sum total of zero extraterrestrial civilizations that we can observe. The Great Filter must therefore be powerful enough — which is to say, the critical steps must be improbable enough — that even with many billions of rolls of the dice, one ends up with nothing: no aliens, no spacecraft, no signals, at least none that we can detect in our neck of the woods.”Humans’ great filter Climate change caused by the development of advanced civilization could very well be that filter in our case. David Wallace-Wells suggested this possibility in a recent feature for New York Magazine:”In a universe that is many billions of years old, with star systems separated as much by time as by space, civilizations might emerge and develop and burn themselves up simply too fast to ever find one another. Peter Ward, a charismatic paleontologist among those responsible for discovering that the planet’s mass extinctions were caused by greenhouse gas, calls this the “Great Filter”: “Civilizations rise, but there’s an environmental filter that causes them to die off again and disappear fairly quickly,” he told me. “If you look at planet Earth, the filtering we’ve had in the past has been in these mass extinctions.” The mass extinction we are now living through has only just begun; so much more dying is coming.”Scientists are currently debating whether we are now in the midst of the Earth’s sixth mass extinction event or simply approaching it. Either way, the situation is dire — the existential risks posed by a worst-case climate change scenario are real.If those risks do eventually become serious enough to act as humans’ „Great Filter,” it may be too late for us to communicate with anyone else in our universe.NOW WATCH: NASA just discovered the first food source for potential aliens
Science Images Are Coming in From Humanity’s First Flyby of Jupiter’s Great Red Spot The New York Observer Wed, Jul 12 10:52 AM PDTFor the first time ever, scientists and researchers will be able to see, in detail, the enormous Great Red Spot first noticed on Jupiter in the 1600s but continuously observed since 1830. NASA’s Juno spacecraft launched in August of 2011 and just completed a flyby of the spot on July 10th. The spacecraft captured images of what’s actually a massive storm raging on the planet’s surface.That data is starting to be received by NASA.The agency is encouraging citizen-scientists like Jason Major to process the raw images being beamed from the spacecraft.
