Re: Pushing the envelope - renewing the mission

Andrew,

Just for the record, I've never had the slightest reservation about you climbing any tree you wish. Limiting the climbing crew outside DCR to ENTS members on "official" business will insure that we can continue our mission work which well evolve over time. With respect to worthy white pines, yes, New England has countless fine trees in the 115 to 130-foot height range. No shortage for recreational purposes.

Part of pushing the envelope includes engineering new methods for gathering data that may have scientific uses. Gary and I have completed the homemade transit and I'm begun testing it. I expect this is the first of several homemade transits that will allow us to practice our craft at an advanced level. Exciting stuff.

This is something as a druid I already know and I am sure many of us here on the ENTS list already know. But it is so nice to read medical and scientific backing to it.

New Tallest Hardwood Species For California

I just got an email from Zane Moore who was measuring trees in the south SF Bay Area. He reportedly measured a california sycamore (planatus racemosa) with laser and digital transit at 152.6 ft. The dbh of this tree is just shy of 6'. This tree makes a very short list of California hardwoods that surpass 150 ft. There is the Henley Oak, a valley oak that stands 151 ft, a Bay Laurel that stand 151.4 ft in Russian River Valley. I think there is probably a cottonwood and a tan oak somewhere in Northern California that surpass 150 ft but so far non have been located. Other tallest California hardwoods included 143 ft Tan Oak in Big Basin and a 142.6 ft giant chinquapin in Redwood National Park. That's it !

The Eastern syacamore is generally a larger and taller species. This 152.6 ft California sycamore is just over the top.

Students with Physical Disabilities to Pursue Field Biology

RESEARCH OPPORTUNITY!
by Tree Climbers International, Inc. on Friday, November 18, 2011 at 2:57pm

http://www.facebook.com/notes/tree-climbers-international-inc/research-opportunity/244837505577802

REU Site | 3D Invertebrate Herbivory and Biodiversity in Deciduous North American Forest Canopies:

Inspiring Students with Physical Disabilities to Pursue Field Biology
W.R. Miller, E. McCord, and M. Lowman

Looking for a different Research Experience?
Looking for a new suite of skills?
Looking for a physical challenge?
Looking for a research publication?
Looking for a bit of adventure?
Looking to be part of the future of the planet?

READ ON...

The Research Opportunity

The Principle Investigator Team has proposed a three dimensional research project to define the Taxonomy, Distribution & Herbivory of Tardigrades and Insects in the Canopy of Four Types of North American Forests.

This project is a fast paced travel, tree climbing, data collection internship and not for the timid.

You will be professionally trained to ascend into the canopy to conduct ecological research.

You will measure the impact of micro and macro invertebrates on the habitat and establish a baseline from which change can be measured. This is the cutting edge of ecological analysis in a world impacted by climate change.

You will meet and network with the scientists and graduate students at the Harvard Forest Research Station and the North Carolina Museum of Natural History.

You will use remote sensing, GIS, HPLC, GC-MS, and a Scanning Electron Microscope.

You will be employed for the summer, and have a part time job for the next two semesters.

You will collaborate with the PIs to prepare your data for presentation and publication.

You will attend a regional, national or international meeting and present your results.

You will become part of a small team of young scientists who are defining the condition of the temperate forests before global warming exerts pressure for the forests and canopy to change.


We Are Recruiting Students With Ambulatory Disabilities

There are no barriers to using microscopes, instruments, or accessing the tops of trees for students with ambulatory disabilities. The PI Team has reserved a portion of these REU Internships for students who might not normally consider themselves competitive for an aggressive, high profile, field research project due to an ambulatory disability.

PROGRAM NOTE

This is a Preliminary Exploratory Announcement. The National Science Foundation will not announce program awards until February, while the PI Team understands there is no guarantee of funding, we are asking for an expression of interest from students with ambulatory disabilities such that when funded we can move quickly into the recruiting phase.

If interested please contact Dr. William Miller at 785-594-8379 or William.Miller@BakerU.edu


The PI Team:

William R. Miller, Department of Biology, Baker University, Baldwin City, Kansas 66006

Re: More World Records From Zane Moore

NTS,

I am amazed when I consider what we are witnessing. Thanks to Michael and team, we're now getting confirmations of deciduous trees in California that exceed heights beyond what we could have imagined. And it is almost 2012! These latest numbers confirm beyond a shadow of a doubt the value of NTS and associates - if there had been any previous doubts. With LIDAR, new ground-based measurement techniques, a growing team of super Ents searching for new records, and thanks to Ed, the web-based apparatus to communicate effectively, we're steamrolling. 2011 has been a heck of a year.

Who among us would have predicted that we could have legitimately reached 170 feet in Ohio? Consider the sheer number of 20-foot girth live oaks that Larry has confirmed with who knows how many left for him to discover. Then there are the great tuliptrees that Will, Josh, Jess, Mike, etc. in the Southeast are finding. Thanks to LIDAR and Jess, Georgia has come up on the radar scope. And we keep locating more sites with impressive white pines here in New England. Bart is off again to Costa Rica searching for big trees. Kouta and Geroen are ferreting out the best in Europe. The list of accomplishments goes on. When they are strung out in many postings spread over many months, we can lose sight of just how many discoveries have been made.

What's left? A few years ago, I believed that we were near the end of the discovery process. How wrong I was.

Could 2012 exceed all previous years of discovery?

Arboreally Speaking, the Good Old Growth Curve Is a Delusion

Arboreally Speaking, the ‘Good Old Growth Curve Is a Delusion’
by Neil Pederson | 12.27.2011 at 6:32pm

http://blogs.ei.columbia.edu/2011/12/27/arboreally-speaking-the-good-old-growth-curve-is-a-delusion/

In the previous post, I outlined the argument lighting up parts of the New Jersey legislature and the human elements of its ecological communities. Briefly, one reason some people are using to promote logging on public lands is the perception that old trees and forests are dying of old age. While there are other arguments as a part of the bill, like the fact that because forested ecosystems are maturing, species that use younger forests are declining, this “old trees are in decline” argument has led to much logging of old forests. I would argue it doesn’t have to be that way.

http://blogs.ei.columbia.edu/wp-content/uploads/2011/12/broadleafCoresSigned1-600x315.jpg

I will spare you many of the details from the scientific literature. But there is a plethora of papers indicating old trees and forests are dying of anything but old age...

Re: Dive bomb bird in the hand

I am sharing rehab of Freddy with my friend and fellow fosterer Arina. We are still trying to correctly diagnose his illness, it is either trichomoniasis (protozoa that attack the esophagus) or a type of Avian Pox (bacterial) that attacks the mucous membranes. (Avian Pox usually affects the non-feathered parts of a bird, but this more serious type attacks inside the mouth. Oy vey...) But he is under the best care possible, a vet, a vet tech, and senior rehabber. And us. No slouches at this point, but always learning.

Freddy is soooo energetic though and hates being confines in any way, but we have to confine him for part of the time if other birds are out. Both diseases are highly contagious. He is just the greatest bird.

If I already posted this, I'm sorry....

Oak Opening Project

NTS,

I'm not sure if this is the best place for this post, but here it is anyway.

I planted my first oak from an acorn in the fall of 1994. Actually I planted a couple, one northern red oak and one bur oak. Not long after this I came up with this idea of planting a bunch of acorns in a park nearly adjacent to where I grew up and where my parents still live. Amazingly they allowed me to plant a bunch of bur oaks, white oaks and swamp white oaks in an old field of about 30 acres or so. This old field was quickly becoming overrun by autumn olive and I was hoping to slowly remove these while planting the oaks. Initially I tried growing acorns in containers that I built out of plywood or by using 1/2 gallon milk cartons. Transplanting these to the field didn't work as well as I'd hoped so I switched to planting the acorns in place. In this first post I'm mostly just going to describe this process, but first I wanted to say a little more about where I ended up going to collect acorns as well as a little about the site.

I thought it would be cool to highlight the diversity within each species by collecting from all over North America. This turned out to be a lot harder than I expected. My hope was that there would be significant morphological differences within each species that anyone could easily see. I was also planning on measuring the growth of each tree to determine whether or not the source of the seed would greatly influence their growth rate. The field is rectangular with the east-west length being greater than the north-south length. There is a marsh in the north central part of the field and a second marsh that is mostly on private property at the northeastern end of the field. In wet springs these two marshes will connect to form one large marsh. Acorns were planted in the field based on where they were collected in North America, so bur oak acorns from Vermont were planted in the northeastern part of the field while bur oak acorns from Oklahoma were planted in the southwestern part of the field. A large hill just to the south of the field helps to keep the southern end of the field in snow a good deal longer than the rest of the field. This should help to keep the southern trees from breaking dormancy too early...I hope. I allowed the swamp white oaks to break the rules a bit because I wanted all of them to be planted at the edge of the marshes and it was often not possible to plant them within the invisible lines of their respective states.

Below is a picture of the field looking to the northeast.
Oak8.jpg

And one looking north towards the marsh at the north central part of the field.
Oak7.jpg

So, I'm now going to describe how I went about planting most of the acorns. I always tried to collect at least a hundred acorns from each tree or trees that would represent a particular state. I usually failed but that was the intent. Initially I tried to collect from AF champion trees for each state. I eventually dropped this idea for reasons that I will discuss later. Acorns were then given the float test in water and all "floaters" were thrown out. However, in a number of cases I didn't have many "sinkers" so I would keep and mark the "floaters" with a black magic marker (sharpie). I would use these "floaters" as spacers between the "sinkers" so that the highest quality seeds were not all lumped together. Although "floaters" are less likely to germinate than "sinkers", sometimes much less likely, they are worth planting if you are low on acorns. "Floaters" will germinate better if you soak them overnight in water (some will sink long before this). Even when I had all "sinkers" I would try to make sure that the largest, best-looking seeds were evenly spaced at planting time. I always tried to plant the seeds as quickly as possible in fall and if that was not possible I would store them in plastic zip-lock baggies in the refrigerator crisper until I could plant them. I held some far southern material (Tennessee, Arkansas, Oklahoma, Texas etc.) in the crisper all winter long because they were often collected too late in the season to plant in Michigan. These were then planted in April.

At the time of planting a 2' x 2' piece of sod was dug out with a spade and flipped upside down after all grasses were removed by hand pulling. The depth of soil removed and flipped was about 8-12". The spade was then used to break up the soil for planting the acorns. If I had 100 acorns I would evenly space them in a 10 x 10 grid and push them a couple inches into the soil and then cover the little holes up. If I only had a few I always tried to place the best acorn near the center. I then covered the soil with cut straw to insulate the soil and to keep it from washing away during rains. I often piled the straw up quite a bit more for acorns from more southerly locations. I removed the straw in the spring if it was quite heavy. Below is a picture after this stage.
Oak1.jpg

Now it was time to add the cage to protect the acorns from rodents. I constructed this cage from a single 3' x 10' piece of 1/4" hardware cloth. These are sold at hardware stores in 10' rolled up sections. I use the wire that holds these rolls together to sew the two ends of the hardware cloth together. There is always much more than you need for this task. I then place the cage over the acorns, center it and mark the ground along the inside edge of the cage with a plastic tent stake. Spade about 3/4 of the way around along the line and then place the cage in the spaded portion to make sure it will still fit if you spade along the remaining line. I try to make sure the cage is between 4 and 6 inches deep to keep the voles at bay and the wind from blowing the cage away. I like to tamp the soil around the inside and outside of the cage edge with the spade but it is probably better to use something that isn't sharp. The final step is to add a roof. I cut a 3' x 10' piece of 1/2" hardware cloth into three pieces for three tops. Each top can be wired to the cage with the same wire as was used to sew the cage together. I think this top is mainly to keep squirrels out because I think voles are afraid to climb over such a fence in an open field. I use 1/2" because I don't think voles are getting in this way and because it does a better job of keeping snow from building up and crushing the cage than 1/4" mesh. Below is a picture of a completed cage.
Oak2.jpg

With a little luck most of the acorns will germinate and you'll end up with something that looks like the Tennessee bur oaks below after a season of growth. I actually planted these ones a little beyond the usual 2' x 2' planting area.
Oak21.jpg

Eventually the top will need to be removed. Don't do this before you are ready to protect your trees! In a truly stupid move, I once removed a top in the evening after sunset. The next morning I saw some deer walking away from the general direction of the trees I left unprotected. Naturally they shredded the tops of my poor little trees! I usually remove the tops when the tallest tree has reached 18-30" depending on how fast the trees were growing. They usually grow slowly until they reach around 2' and then they take off...at least that has been my experience with most of these trees in Michigan. After taking the top off, a bigger, deer fence is needed. I use a 5' x 20' piece to make a little more than a 6' diameter perimeter. The fence needs to be strong enough to keep deer out and if it's in a windy location I like to use 3 good, metal fence posts.

Picture below is of Kentucky swamp white oaks with top removed from the cage but before addition of deer fence.
Oak19.jpg

The next picture is of Indiana white oaks with top removed from the cage and a ratty, temporary fence to keep deer from eating them.
Oak20.jpg

The picture below is of Virginia bur oaks and the deer fence is actually not 6' in diameter...I need an upgrade. The hill to the south can be seen in the background.
Oak3.jpg

The other big difference with the previous picture is that the 1/4" mesh cage has been removed. I need to put small vole guards around these trees because they are still quite susceptible to these little critters.

I'll talk about the growth of these trees in my next post.

Re: Devil's Den Preserve, Redding, CT

That 134.5 tulip beats the biggest one we found. Off the Pent trail we found a grove of tulips and measured 4 of the 7 or so.They were 6;4" cbh @ 105', 6'7" cbh @ 102, 7'10" @ 109' and 8'31/2" cbh @ 110'. Off the Saugatuck trail we found a double tulip, 10'6" @ 101" and a shagbark hickory, 6'6" cbh @ 95' and measured a oak, about 6' cbh @ 101'. There was alot of tulips along the way in the 100' range. For the large number of stone walls, I found none of the gnarly old maple or oaks usually found with the walls. I counted the rings on a fallen pine tree that had been dead for a while and recently cut up. There was about 80 rings and that goes along with the 30 charcoal producing kilns that operated here between the 1800's and up to 1920. Sam

Re: Arborists and Recreational Tree Climbers

... I'm happy to assist the ENTS on whatever tree they would like to do manual measuring, if it happens to the "tallest", whatever, so be it. More discussion is needed on this issue, it can get polarized fast but I don't think it needs to be.
-Andrew

I'm a relatively new (4 months old) rec tree climber and even newer to NTS, but I am happy to say that I haven't ever sensed any animosity between arborists/NTS/and recreational tree climbers. Of course, I'm an isolated climber and only interact with other tree afficionados on forums like this so my experience is limited. I couldn't agree more with Andrew's comment above. Curiosity and appreciation for trees is what first got me into the canopy, but from the moment of my first climb, I wanted to find answers about the physical limitations on tree size, how other animals, insects, and plants utilize forest trees, when the trees folliate, defolliate, species identification and range, etc. I first found the american forest big tree database and point notation system. That gave me another "excuse" to visit prominent trees in my town and along my commute to record their point value. Then a friend on the Big Tree Hunters Facebook group (Tom Robinson) pointed me to NTS. I feel right at home here. I don't have a clinometer and rangefinder, but I love reading the posts from tree lovers of all stripes. My current self imposed tree project is learning about the hemi-parasitic relationship between mistletoe and eastern hardwoods. I hope to climb a couple of mistletoe infested trees and report back with some pictures and my observations.

Andrew-

I think you can rightfully claim several sites, now in Ohio, with 160+' tuliptrees, since these sites were historically in an area that once was part of Connecticut :)

Rescuing the Birds Many Hate (Jennifer Dudley)

Rescuing the Birds Many Hate

http://www.nytimes.com/2012/02/05/nyregion/rescuing-the-birds-many-love-to-hate.html?pagewanted=2&_r=2&ref=nyregionspecial

JUST as they ignore the pigeons that make up so much of their city’s meager wildlife, passers-by paid little attention to the curious scene on 29th Street and Ninth Avenue one brisk morning in December.

05jpPIGEON2-popup.jpg

Jennifer Dudley of New York City Pigeon Rescue Central brought a bird to be X-rayed by Karen Heidgerd last month.

Jennifer Dudley, 44, a strawberry-blond opera singer, studied the corner of a mail distribution center entrance. A rumpled pink bathroom towel stained with bird feces lay on the ground. Nearby were a splay of cracker bits and the bottom half of a crudely cut plastic cup.

“They probably told him to shoo,” Ms. Dudley said, hypothesizing that building security had ushered the wounded pigeon from its resting place.

Another clue: “This should be green,” she added, standing above a mound of dark excrement a few steps away. “He’s definitely sick, but not starving to death.”

Path of tsunami debris mapped out


Almost a year after the Japanese Tohoku earthquake and mega-tsunami, the Pacific Ocean is still dealing with the consequences of the catastrophe. A mass of debris was washed out to sea as floodwaters receded from the land, and some of that wreckage continues to float around the ocean. Most of it headed eastwards, according to modelling work by the Hawaii-based International Pacific Research Center.

Its staff have given an update to this week's biennial Ocean Sciences meeting. "We can only use our model to make projections," explained International Pacific Research Center (IPRC) scientific computer programmer Jan Hafner. "So far, the debris field has spread in length more than 2,000 nautical miles, and is more than 1,000 nautical miles wide," he told BBC News.

That is approaching 4,000km by 2,000km.

Costa Rica Trees & Natural history #1

I will be sending a series of posts in the next couple of weeks comprising photos and descriptions of trees and animals and narrations of experiences from one partial work trip to the Peruvian Amazon last September, and another trip with my wife to Costa Rica in December-January. Having learned the proper way to measure trees from Bob Leverett and having unusual and frequent access to Central and South America I figured NTS folks might enjoy these posts, as they are rare on the bulletin board.

My holy grail in Central and South America is to find a Neotropical emergent tree over 200 feet tall. My friend Phil Wittman did measure with proper protocol one Ceiba pentandra tree, that I had previously posted images for, at 180' height. It had been previously estimated at 220'. Though it is often said that Kapok trees (a common name which actually refers to two or more species) from which cottony seed floss is collected for stuffing life vests and mattresses, exceed 200' in height, I have not come across any that were clearly accurately measured, with a clearly described methodology, that achieved that height. Instead it seems that there are several accounts, but the authors all seem to quote each other when you try to trace the origin of the actual figures.

I am optimistic that this goal will be realized because in these tropical forests, there is not one or two, but 10's of emergent species that may aspire to reach such a height. To date, with the standard caveat "as far as I know" no Neotropical tree has unequivocally achieved this stature and been reliably measured. If you have information to the contrary, please post it with the source, or let me know.

Before getting into the images and descriptions I would like to set the stage for what I have been trying to do and what it is like to pursue my goal in the Central and South American tropical forest environments. In Peru I build canopy walkways for a living and have been returning regularly for 22 years to inspect and maintain the systems that my associates and I have designed and built. I have been visiting Peru and Ecuador off and on since 1984, having taken 25 trips to the Amazon Basin. I have also worked in Belize and Costa Rica and have been to Central America probably around 20 times for work, biological research, to bring groups of college students down for tropical ecology studies and to visit friends. My main study interest in the Neotropics was originally certain orders of arachnids (no, not all arachnids are spiders- think ticks and mites,scorpions,pseodoscorpions and harvestmen<daddy longlegs>as some examples of arachnid orders), but more recently, with the help of Andrew Joslin and Bob Leverett, I have developed a new obsession, and that is old growth emergent trees. Since folks such as Will Blozan and Bob Leverett know more about temperate trees than I can ever hope to learn, I figured I would take advantage of my access to the New World tropics to learn something about the Emergent trees to be found there. Unlike my home in the Eastern US, where only the White Pine and Tulip Tree tend to grow above the canopy and then spread out above the other trees, there are certainly well over 20 true emergent tree species in the Peruvian Amazon. In the Eastern US, other trees such as the Cotton Woods and Sycamores achieve impressive heights, but their pattern tends to be different and often they grow in a less dense flood plane environment where a tall straight growth architecture is less important in achieving dominance.

While visiting Costa Rica my wife Connie and I stayed at friends Ralph and Margarita in Alta del Monte west of the continental divide. For a few days we also stayed with Margaritas extended family and at the Tirimbina Research Center, both located in the state of Sarapiqui on the Caribbean side of the divide. We were able to get a discounted rate at Tirimbina as I provided a climbing seminar for some staff members at the center. I also spent time on a night climb with my friend Witold Lapinski and his girl friend who was visiting at the time.

Witold is a German doctoral student studying the behavior of wandering spiders, a behavioral group which includes spiders that hunt down their prey without making webs. On nights that are not too rainy he climbs one of the several trees he has rigged to observe these spiders for several hours using his head lamp. He says he has collected enough data in the past year or so to publish probably around 20 papers. Among the trees he has rigged are 3 Kapoks (Ceiba pentandra), one of which exceeds 150 feet in height. Unfortunately I did not get photos of the largest Kapoks in the day time. I did however get a few shots of various creatures in the top of one of the taller trees he rigged. We had to be careful in this tree as there was apparently a Bullet Ant (Paraponera clavata) nest in the top of the tree in a crotch full of soil, and the beasts were quite actively foraging on the limbs. They are called bullet ants because their sting is said to feel like being shot with a bullet. Though this description is a bit of an exaggeration, the sting is extremely painful and the pain can last for as long as 24 hours, though Witold says he seems to have developed an immunity to them such that it is more of an annoyance when he gets stung as opposed to the expected harrowing experience that some of my associates have been unfortunate enough to go through.

Fortunately I have only been stung by a member of the Bullet ants larger sister genus. This happened 2 years ago in the Peruvian Amazon. The name of this other ant genus is Dinoponera, probably because it is a quarter of an inch longer than the one inch long bullet ant and ,as such, is the dinosaur of the ants. Fortunately for me, this largest of new world ants, has a less potent sting than its smaller but more fearsome sister genus. The sting occurred two hours after I had been photographing these ants coming from a nest at the base of a tree in a reserve on the Río Marañón in Northern Peru. I was suddenly awakened when I rolled over during an afternoon siesta to find that one of the these ants had crawled up my pants leg during the photo shoot and had now given me a wicked sting on my upper thigh just below my -- better not go there.

Any way, identifying giant trees in the Amazon or Central America can be a bit daunting. I thought it was quite an accomplishment when I ran my tree service in Chapel Hill North Carolina and learned the Latin names of 21 oak species, but compared to dealing with an environment where, according to some sources, there can be over 600 species of trees on a single hectare (about 2.5 acres), that was child's play. This is why I have limited my scope to only the tall emergent trees, aside from the fact that they hold the most interest for me, and are the most exciting to climb. So now I guess it's time for the first image of trees in a Costa Rican ravine:

The deep light dappled ravine provided constant surprises such as gorgeous waterfalls and swimming holes to die for even though no one ever uses them. The steep cliffs and immense boulders gave my friend Bob Lucas and I a feeling of being small in this amazing place where the giant cashew trees grew so frequently that we did not bother with the dozens of big trees that appeared to be only 12' or less in circumference. There was always something awe inspiring around each curve and meander of the stream.

Bob and I had to zig zag across the stream and boulder hop to find good walking space in and on the sides of the rocky stream bed. As we moved along we looked up at the long leaves which also coated much of the ground below with a thick crunchy layer from these Wild Cashew Trees. The large leaves (up to 16 inches long) from these trees create a layer of detritus and barely decomposed dry leaves a foot or more thick. Here is the view looking up.

Interestingly these trees which were quite large and tall were also the most common trees along the banks of the stream. This interesting tree species is in the Anacardiaceae family which also contains the Sumacs and poison Ivy. This relationship may explain why allergic reactions to the raw nuts and fruit of the cultivated species (Anacardium occidentale) are not uncommon. These "Espave" trees were clearly the dominant emergents in several pacific slope ravines that I visited. What follows is some of the images and data collected during one excursion with my friend Bob Lucas, some of the images are from his own property.

This was the first tree we measured on this particular hike. From here we wended our way down the river to our next tree.

Unfortunately we had to make time in order to make it to a cut to get out of the ravine and to a road by nightfall, so many large species were not able to be identified in this exploratory trip. All height measurements were taken simply by pointing the Nikon 440 rangefinder straight up, so most of the trees were probably a couple of feet taller.

Ambove was our tallest Wild Cashew, yet there is a more imposing one coming up in the next post of this series. Below is pictured a strange looking unidentified species that required a photo nevertheless.

I will be doing 4 or 5 more posts including one about Tirimbina Research Center, another ravine hike including a report on a massive Ceiba pentandra (Kapok Tree) and a couple about trees and beasts in the Peruvian Amazon.

Re: Facebook/ Information Gathering

BTW My apologies to Ed Frank. There used to be a different individual in my life who went by 'Ed' and whose smarmy, manipulatively bullying behavior I had in mind when I wrote this:

Well, sure. But it's shear breadth is somewhat creepifying (Hi, I'm Ed from Upyur Wahzoo Inc. and I understand you better than you probably understand yourself. Don't believe me? Let me show you the graphs and then we'll talk business. Uh... severe information asymmetry is fundamentally a poor position from which to negotiate)

Definitely. I'm still willing to joust with fb for now. Google scares me more, pretty much all enveloping scheme to take over the planet. My working theory is national governments will become superfluous, Google, fb and/or whatever other "friendly" monster comes along will be in charge. It's a different implementation of the Orwellian scheme that was expected by the futurists. No one expected the population to collaborate so enthusiastically with the overseers ;-)
-AJ

I don't know about FB or Google really wielding power. But once they build up a profile or your behavior, I do see that information being of much interest to Insurance co and banks. AKA any company having a stake in your risk profile. I mean gee, how much of your lifestyle can be figured out by tracking your face through pictures posted online or following you around to your favorite restaurants using foursquare. They could figure out your diet and what risky activities you participate in and assigns your health/life insurance premiums accordingly. That would be brutally honest I suppose but creepily invasive too.

The computational power of computers and the connectivity of the internet is sending us all back to the village.

That's the good part, since you can belong to a several different villages, have the best of both worlds. Question is when the going gets rough will your village rally behind you the way they might in a physical village? Or will you be staring at affirmative slogans, cute cat photos and targeted ads as your ship goes down?
-AJ

I have my doubts. Fundamentally virtual communities let us have our cake and eat it too in the sense we only deal with them at our convenience and when we have a common interest, and only that common interest. Going out of our way to help someone is fundamentally inconvenient and we're kinda out of practice. James H. Kunstler points this out as one of the side affects of the loss of day to day public space inherent in the car orientated design of suburbia.

I believe they are all norway maples. We also had some apple wood from my tree.

Re: Pinus strobus in Meshomasic State Forest

I agree. They are my favorites as well.

I am interested to see what Michael can do with the sounds of the different tree species in a musical context.
