GPS World discusses Russia's recent launch of three more GLONASS satellites. This brings the total available satellites to 18, enough for navigation in Russia. Russia hopes to have a complete constellation of GPS satellites working by 2009. There was a recent news story of President Putin with his dog showing how a GLONASS-based GPS tracking device was now possible.
This follows last week's successful launch of a new GPS satellite, also described in GPS World. The new GPS IIR-18 (M) satellite will replace an existing older unit. It provides a stronger civilian signal and some new capabilities for military navigation.
This news is exciting for anyone interested in GPS. Within a few years we will have the choice of receivers using NAVSTAR (American), Galileo (European), or GLONASS (Russian). There will certainly be combinations of the different systems for even better accuracy and reliability. The combinations may be subscription-based for the extra service. I am sure there will be intense competition among providers to provide good deals and packages.
Maybe they will even solve the problem of good reception under a closed forest canopy with a low cost receiver!

From the reports I heard, I feel optimistic that this campaign may be successful. First, it is a locally initiated campaign. The people seem to be behind it, rather than having it imposed from outside. They have chosen some interesting species. In addition to teak and other timber species they will be planting fruit trees that people want.
As I saw in Africa, tree planting campaigns will only work if they have popular support. Otherwise it's just too hard to make the tree-planting a success. This doesn't resolve the problem of forest clearing and fires, but it does point in the right direction.

One of the first blog entries I made last year was on the chestnut tree outside the Anne Frank house in Amsterdam. This was the tree she mentioned frequently in her diary during her family's two year hiding from the Nazis.
The city of Amsterdam wants to remove the tree because of its advanced state of decay. Now, a year later, people who want to save the tree have sued to prevent it being cut. After hearing arguments on both sides a judge ordered the city to hold off until February. Here is a link to a BBC story on the tree.
It's interesting that the managers of the Anne Frank Museum at the house want the tree removed to prevent injury to visitors. They would rather replant a new, healthy tree. Sounds like a good idea to me.

For a number of reasons children are losing this contact with the outdoors. Electronic toys, parents' fears, and a too-structured lifestyle are just some of the reasons. He says that the increase in childhood obesity, increased ADD, and the increase of stressed children are just some of the consequences. In part he blamed his own profession, journalism, for creating a climate of fear by magnifying all the dangers out there, that results in many families keeping their children under house arrest.
He cited a number of initiatives and programs to get children back outdoors. Although he says it's unlikely we will ever go back to the days of letting children roam free, we have to make sure children have that connection to the outdoors that all people need.
He really connected to this audience of foresters. Just about all of us had our special outdoor place growing up. Most of us still have one today. He did inspire all of us to try harder to find ways to work with children. That will be good for them and good for the profession of forestry.
Here is a link to Louv's web page and a link to his books in Google search.
Louv did a book signing later in the day. There was a huge line, over a hundred people I guess, waiting. The SAF shop even sold out of the book.
Another new tool is a brand new website interface for the FIA national forest inventory data. Previously, we had to wait for the inventory reports to come out in book form. Now the Forest Service has created a modern interface to zero in on the forestry statistics even down to the local data. fiatools.fs.fed.us The people demonstrating the site told me it just came on line last week. The help files aren't even up yet. It will be fun to learn.

This stack of old railroad ties I found next to an exhibit of a restored railroad caboose in Norlo Park in Guilford township, Pa. The ties reminded me of how important creosote preservation was for the railroad and almost all other outdoor uses of wood.
Of course creosote, a type of oil, is very toxic. It also leaked from the wood creating even more hazards. The sites of creosote factories are Superfund waste sites. For example, the old creosote plant in Pensacola, FL was a massive cleanup headache. Fortunately, we have other ways to preserve wood. Railroad ties are often made from other materials. we should never forget about the imoprtance of creosote, though.

Gates also has his own photo gallery with some amazing shots, many from the watchtower.
There are fewer and fewer manned lookouts (only 800 left) around as the US Forest Service and State Forest Services go to modern technologies. It takes a special person to endure living there. But I'm sure there are advantages to having a pair of human eyes watching the skyline for fires.
Many forest technology students want to work fighting fires. Not so many would want to work in a fire tower I think.

At the reservoir Dave Gillen discusses the purpose of the watershed, butternut canker, the importance of hickories for biological diversity and wildlife feed, and stand dynamics in an old norway spruce plantation.
Matt Reitzel described a 20+ acre clearcut to remove some stagnant softwood plantations, the problems with invasive plants, the use of herbicides, the re-establishment of american chestnut, and hybrid loblolly pine planting.
Adam Luther described a hardwood removal cut to release oaks. The twenty acre site was then fenced to keep deer. Today the oak stand is doing very well. The acorns were falling like rain.
The deer fence is essential.

Given that the sets of photos we are using were taken in 1977, the element of time must also be included in the interpretation. Some areas have been harvested and others have grow in from previous harvests. Little of the area has changed through human use, however.
Here is a Google map of the sites the class visited:

Digital pictures were taken at each stop and then geotagged with the location coordinates. Follow this link to see the geotagged images on a Yahoo Map in Flickr. Picasa albums also offers geotagging on a Google map as shown in this link. Each provider and format has its own advantages. There is probably a universal tool out there to combine these into one view.

The articles quotes experts from the Pennsylvania Bureau of Forestry and Cumberland Valley Tree Co. that oakworm attacks tend to be very localized. There is usually no need to spray, although homeowners can if they wish.
Forest pest stories seldom make the news unless there is something catastrophic going on. Few people know the war for existence going in the forest ecosystems just a few feet from their doors.

The news all weekend has been full of the Greek wildfire story. Even the site of the birth of the Olympic games is threatened. Both the New York Times and The Washington Post have carried a story by John F. L. Ross with this quote:
Forest fires are common during Greece's hot, dry summers _ but nothing has approached the scale of the last three days. Arson is often suspected, mostly to clear land for development. No construction is allowed in Greece in areas designated as forest land, and fires are sometimes set to circumvent the law.
It shows that even in forest ecosystems prone to fire, their number and severity are strongly influenced by social considerations. The politics and economics of land ownership count a lot. This has been true every place I have worked, from Pennsylvania to Burkina Faso. The toll of human suffering from these fires is unimaginable. I hope they are put under control soon.
Here is a link to a photoset from a Greek photographer on Flickr.

Forest technology is constantly evolving. Every year instructors gather for CEFTS (Council of Eastern Forest Technician Schools) meetings. We share teaching ideas and discuss issues such as new student recruitment, student retention, and accreditation. This year's meeting was held in Fort Kent, Me and sponsored by the University of Maine at Fort Kent. Everyone looks forward to the field visits and technical sessions. Among these were: the uses of GIS and GPS in timber harvesting, muskellenge fish migration on the Fish River, intensive silviculture in the spruce forests on Irving Co. forests, state forest lands management to protect wildlife habitat, and use conflicts along the Allagash Wilderness Waterway. We also visited the Tenth Mountain Ski Center, a world class biathlon facility. Check out the meeting highlights page here.

I'm working for Weyerhaeuser this summer in the North Louisiana Timberlands Region. This region of the company manages nearly 750,000 acres in 22 parishes (counties) in Louisiana, 6 counties in eastern Texas, and 7 counties in southern Arkansas. There are around 53 employees and 45 logging contractors. Weyerhaeuser practices intensive forest management on even-aged stands that are mostly loblolly pine plantations. The company clearcuts around 20,000 acres a year, which they then site-prep and re-plant-- a total of nearly 9 million trees planted a year. Weyerhaeuser is also SFI certified. This region has two lumbermills and three veneer mills, with the major source of wood being supplied from company lands, followed by logs shipped in from other contractors, and then timber from private landowners.
As part of my summer internship, I have done various jobs with people of various positions in the company. So far, I have: cruised and marked timber and pulpwood on company as well as private lands; investigated disputes regarding property lines; inspected roads for BMP (best-management practices) audits; done audits on loggers for BMP work and safety equipment; located tracts and made maps on a GIS program; and compiled and checked tracts for future harvest and/or conversion.
I have worked in Louisiana and Texas so far and it is definitely a change of pace when compared to the hardwood forests of Pennsylvania. The advantage of our two-year program compared to a four-year degree is that we already have the technical training after our first year-- many people were very astonished that I knew how to cruise after only one year of school. Also, the system of mapping in Louisiana is the Section, Township, and Range, which makes it very easy to find where you need to go! I have only seen one alligator-- in the lake behind our office. I've also seen two roadrunners. But so far, I haven't seen any snakes- rattlers or mocasins- and I want to keep it that way!
The second picture is of a longleaf pine in it's "grass stage," where it needs to be released by fire.
The third and fourth pictures are of a site prep machine that simultaneously shears rows and plows beds for planting seedlings. The beds are a pre-determined length, which is entered into a GPS receiver on the machine. This then directs the operator where to plow-- down to the foot.
The fifth picture is of me in front of a loblolly pine in Texas that is nearly 4 feet in diameter.
And last, but not least: everyone loves a log truck.

While visiting family in Westfield, MA I came across this fine example of a dawn redwood. It is located in a small park that is slated to be removed to accommodate a new bridge crossing. The city is trying to decide what to do with the tree. Dawn redwood (Metasequoia glyptostroboides) is a fast growing deciduous conifer that was discovered in China in the 1940's and had been considered extinct before. It grows very well in urban settings, although there have been problems with vigor from hybrid inbreeding.
According to a recent article in Westfield's newspaper, The Republican, the city now has to decide how to save the tree or whether to cut it down.
Thanks to Chris Morrill for showing me this tree.

Say Freeport, ME and people will automatically say LL Bean. But located in Yarmouth on Rte. 1 just outside Freeport is DeLorme, famous for its line of atlas and gazetteers of the 50 states. The company also produces its own GIS, diverse mapping software, and now its own GPS receiver. I visited the Map Store at DeLorme last week and wasn't disappointed. There are a large number of mapping books and tools available. They have the entire series of topographic maps for the State of Maine at 1:20,000. I bought some full-size vinyl map covers, a great way to store maps for viewing. I also got a large size UTM-grid and protractor, useful for plotting with topographic maps.
The best thing about visiting Delorme is seeing the giant globe, Eartha. It's a world record.

This is a new tool I found on the Ogle Earth Blog . Simply put, use a map lets you create a map location with a simple link address. When you click on the link you then have the option of viewing the map in Google, Yahoo, or MS Live. With new features you can also add pictures and other annotations.
Here is a map I made for Peaks Island, Maine: http://useamap.com/peaks
Here is another for the Penn State Mont Alto campus: http://useamap.com/MontAlto
It's easy to use and a great way to send maps to someone.

The Mont Alto Woodsmen's Team demonstrated Woodsmen's events for the visiting "Road Scholars" tour on Monday evening (5/14). This is an annual event for new Penn State faculty from all of the Univeristy's campuses to learn more about the Commonwealth over a three day tour of various locations. President Graham Spanier tries the two-man crosscut with Darren Krebs while other team members look on.
Here are articles in the local newspapers:
The Herald-Mail online and the Waynesboro Record Herald.

Students in Dr. Brantley's Plant biology class got a lesson in tree grafting from Jack Winieski (Allegany SAF Executive Director) and Bruce Kile (retired PA Service Forester). In these pictures they are working on pine trees. In a later session they worked on apple trees. Grafting is as much an art as a science and takes a great deal of skill and experience. Thanks Jack and Bruce for your help.
