I am working on a retrospective of remote sensing of forests in California for the centennial. I am trying to highlight some of the pioneering work done by remote sensors that focused on Californian forests from the 1960s through the use of lidar today.
Of course with this topic you must begin with Robert N. Colwell. Dr. Colwell was an internationally renowned remote sensing scientist; he was former associate director of the Space Sciences Laboratory at the UC Berkeley, and he was the instructor of remote sensing in our own Mulford Hall from 1947 until his retirement in 1983. He was NASA co-investigator for Apollo IX, and his research in the 1960s on reflectance and multispectral reconnaissance were the primary basis for selecting the type of sensors and the spectral bands implemented in Landsat. Neat guy, and we all benefit from his intellectual legacy.
Anyway, for this paper, I am going through some of his work as he transitioned from aerial photography to digital imaging, and I came across this picture. Mulford is just off the scene in the upper left corner. In his caption he says:
"Oblique aerial view of Berkeley Campus of University of California taken with Camouflage Detection film." (That is what they used to call color infrared.) "Such photography is superior to any other for certain photo interpretation purposes as indicated by some of the preceding examples. Note in this photo how color values for each species of tree tend to remain uniform from foreground to background because of the superior haze penetration offered by this film. The relatively long wavelengths to which this infrared-sensitive film reacts are scattered but very little by atmospheric haze particles, thus accounting for the uniform color values and for excellent image sharpness." I dig this part: "The original color transparencies have the same color values as seen here and consequently make very attractive panels for lamp shades, although certain of their colors fade upon prolonged exposure to light."
The trend for using maps as home decorations PRE-DATES 1970! Take that hipsters!

There has been a trend toward open access publishing that has been strengthened recently with a number of coincident efforts, for example Randy Scheckman's Nobel Prize talk, and the UC's Open Access policy for example. Some journals are opening up an open access component to their publishing - Remote Sensing of Environment for example now has an open access model as well as subscription model, and some new completely open access journals are coming on line. The open access model means the author pays the publisher for the costs of putting out an article, instead of the publisher charging universities subscription fees to allow access to the journal.
Open access publishing is a great idea, whose time is ripe: publically funded research should be easily assessed by the public; in general the cost of publishing an open access journal is less than that of a regular article. But the rush to open has opened the window to fraudulent enterprises out to make a fast buck. Thus the landscape of open access publishing is often confusing, and there have been a number of great discussion about how to navigate the stormy waters of open access. Here is my wrap up of some of the informative posts out there:
- An article in Nature introducing the term "predatory publishers": "The explosion in open-access publishing has fuelled the rise of questionable operators" http://www.nature.com/news/investigating-journals-the-dark-side-of-publishing-1.12666
- Jeffrey Bealls' list of predatory publishers in 2014: http://scholarlyoa.com/2014/01/02/list-of-predatory-publishers-2014/
- Recently MDPI, who publishes Remote Sensing, an open access journal I have published in several times, was attacked via an email campaign. Here is their response: http://www.mdpi.com/about/announcements/502
Other notes pointed out in the Nature article:
- PLOS ONE, which charges a fee of $1,350 for authors in middle- and high-income countries (UC Berkeley gets a slight price cut), has seen the number of articles it publishes leap from 138 in 2006 to 23,464 last year, making it the world's largest scientific journal.
- In the past year, the UK and US governments, as well as the European Commission, have thrown their weight behind some form of open-access publishing.
I recently attended the 2014 annual meeting of the Western Section of the Wildlife Society in Reno CA. The focus of the conference was on harnessing citizen science toward greater conservation.
I saw some interesting talks in my session (I was clearly the odd-talk-out in a session dominated by animal tracking (I spoke about our SNAMP website evaluation)). For example:
- Peter Bloom discussed red-tailed hawk movements from banded bird recovery. The birds are banded as juveniles and observed by citizens and scientists. In this way their movements can be mapped: across southern California, across the Pacific flyway, and across the US.
- Joe Burnett presented on the use of GSM transmitters to track California condor (the largest flying bird in north America) movement patterns. He caught us up on condor recovery and current threats (lead poisoning from foraging on wild game) to condors. He showed some very nice visualizations of wild condor flights between Ventana and the Pinnacles (including some stops for water and dead animal chomping) from the GSM transmitters and Google Earth.
- Shannon Rich looked at migration patterns of flammulated owls using light-level geolocators. "What is a flammulated owl”? you say: I will tell you. They are super cute tiny owls, with neat flame-like markings on their face and body. Geolocators are small (~1g) that record ambient light levels during the day, and from timing of sunrise and sunset, you can get latitude and longitude. These are not sending out signals, and you need to recapture the owl to download data. As always, I am stunned by the dedication and time it takes for wildlife biologists to gather their careful data on animal movement.
- Russ Bryant talked about native honeybee habitat in North Dakota. He talked about the important services that bees give us: 95 agricultural plants benefit from pollination services (estimated at $15b). I did not know that ND is the top honey producer in the US. Colony collapse across the US has been profound. They used INVEST to explore the role of land cover and bee pollination to produce a pollinator habitat index, and a habitat connectivity for areas where bees had been captured.
In the climate change session, I heard from a range of speakers on practical adaptation strategies, curriculum for climate change education (Whitney Albright), new tools and reports for grassland bird species conservation (Ryan Diguadio), landscape-scale conservation planning for bobcats in the San Diego area (Megan Jennings), and some neat genetics of the SF Bay’s salt marsh harvest mouse (Mark Statham). Also, Curtis Alling talked about local, regional and state climate preparedness planning, and dedicated a slide to cal-adapt.org. Nice!
I also got to catch up briefly with ESPM grads Sarah Sawyer who is now at the Forest Service and Tim Bean, who is thriving at HSU. Alice, he suggested a trip up to Redwood State Park to check out the dark figure of crime in the tall trees.
Forestry education at UC Berkeley began in 1914 with the “Division of Forestry” in the Department of Agriculture. The Department of Forestry was established in 1939 and the School of Forestry in 1946. Forest Summer Camp, the hallmark of the undergraduate program, began at Quincy, California, in 1915 and moved to Meadow Valley in 1917.
Today, alumni of Cal’s forestry program hold critical positions for the management of 95% of the industrial forestlands in California. The research of our alumni and faculty has grown knowledge in the areas of fire, remote sensing and GIS, ecology, climate change, forest economics, the social sciences, and numerous others.
Over the past 100 years, the Cal Forestry program has had an impact on every dimension of the field, and has produced the profession’s most influential thinkers and doers.
