The City of Watsonville has finally submitted their NTMP for 184 acres in the Rattlesnake and Shingle Mill Gulch drainages (Pajaro River Watershed). The NTMP goes to First Review tomorrow. Perhaps it will get returned. Gary Paul is the RPF.
From a June 23, 2008 letter to Plan Submitters: “On June 20th and 21st, California experienced an unprecedented series of lightning cause fires. In total, more than 700 fires have been started and CAL FIRE firefighting resources have been heavily engaged in suppression efforts.
Maybe there was no uproar because people thought the tree clearing was part of the Graham Hill Road Widening project. Or maybe no one cares anymore. Too busy driving madly to and from town.
“An excellent set of 3D visualizations has been added to the Google Earth Outreach Showcase. The visualizations show the state of forests around the world by country. The world has lost close to half of its forests already today, and the continued high pace of deforestation contributes greatly to climate change and the loss of biodiversity. When you first load the Disappearing Forests KML, you will see deforestation rate by area. Red indicates a decline in forests, and the scale indicates the number of hectares changed in the last year. Each country has a placemark which provides very interesting details on the state of the forests. You can also choose from a list of other forest maps in the Places pane under the folder called "Country deforestation data". The KML was developed by David Tryse who also was involved with the Edge of Existence collections highlighted earlier this year in an Outreach Case Study. David used data from the World Resources Institute (WRI): The Last Frontier Forests: Ecosystems and Economies on the Edge (1997), Greenpeace: The Worlds Last Intact Forest Landscapes (2006), and United Nations Food and Agriculture Organization: Global Forest Resources Assessment (2005). David used the following tools: PHP(+Ming for flash counter) & MySQL: XAMPP, World Borders Dataset (+chartAPI-icon idea): thematicmapping. This deforestation visualization is really an excellent example of putting Google Earth KML to work. The graph type used is called a prism map and has been used in many KML files (see list below). Recently a tool Thematic Mapping Engine has been developed by Bjorn Sandvik to make it easy to create your own prism maps for Google Earth. “ http://earth.google.com/outreach/showcase.html - http://www.gearthblog.com/blog/archives/2008/06/disappearing_forests_google_earth_v.html
“Tree leaves and needles keep the same internal temperature on summer days -- close to 21 Celsius -- whether they’re black spruce in northern Canada or palms in Puerto Rico, new research has found. Like the human body, trees have built-in thermostats to cool or warm themselves when necessary, biologist Brent Helliker of the University of Pennsylvania found. How they manage it remains a partial mystery, but the goal is clear: Leaves and needles need to maintain a temperature where photosynthesis can happen easily, which happens to be about 21 C. The pattern holds true for 39 species of trees, measured from the subtropics to Inuvik. Until now, it had been assumed a leaf would be the same temperature as surrounding air. They’re thin, and trees aren’t warm-blooded. Besides, who wanted to take a bunch of ladders and climb all those trees, carrying hundreds of tiny thermometers? So they found another way, by measuring the "isotope," or specific type, of oxygen produced by each tree. Different temperatures produce different mixes of oxygen isotopes. The results showed trees stayed within two degrees of the average temperature of 21.4. To check their findings, the group found a study of Swiss forests using infrared photographs that show temperature. The canopy (treetop) temperature was four to five degrees higher than the cool, background air temperature of Switzerland The finding applies only during daytime, in the spring and summer when photosynthesis is happening. Leaves do cool off at night and in the fall. ” http://www.canada.com/ottawacitizen/news/story.html?id=29b7635e-128f-4eaf-aeeb-f04021e2ef36
