Tree Thursday - Jamaican Caper

Jamaican Caper
Capparis cynophallophora
(KAP-ar-riss sin-oh-fal-oh-FOR-uh)
This 6- to 20-foot-tall, native shrub or small tree  is an upright to spreading plant that is related to plant producing edible capers. The evergreen leaves of the Jamaica Caper are light green above, with fine brown scales below. These glossy, oval leaves are folded together when they first emerge and give the plant's new growth a bronze appearance. Jamaica Caper flowers have very showy, creamy white when first opening and turning a light purple as they age.  The flowering season is usually from April to July, but an errant flower or two can appear anytime during the year.  When ripe, the seed pods burst open and are bright red on the inside.  Seed pods develop from the flowers during July-September.  They ripen at the height of the rainy season. The seeds are wrapped in a sticky, oily, waxy substance that the birds really enjoy. 
Jamaican Capers can be planted as a hedge or pruned into a small tree.   In Fort Lauderdale, you can find Jamaican Capers used as a hedge in Greenfield Park (just south of the Galleria Mall) and as mature trees in front (next to wall) of the Social Center in Holiday Park. 

Growth Rate – Slow
Salt Tolerance – High
Drought Tolerance – High

Energy Conservation Quiz



You can go to the National Geographic website’s Energy Conservation Quiz to find out just how much you know about carbon emissions and how to reduce them.  I scored an 88.  Try to beat that!  :)

Here's some trivia that might help you!

A Carbon Reduction Plan: The Savings
By investing in new technology or adopting approaches already available, we could cut worldwide greenhouse gas emissions by about 38 billion tonnes a year. The money saved from efficiencies in how we use energy could help pay for improvements in how we generate energy, optimize industrial processes and avoid deforestation.

Changing Bulbs
The light-emitting diode (LED) looks like the eco-bulb of the future. With no filament, just a microchip, it uses significantly less energy than an incandescent. But the price is high and reviews are mixed. LED illumination (in photo, center) can range from warm to what technology analyst Michael Kanellos calls "alien autopsy." The bulb casts its light in only one direction, which is fine for recessed lights and for spotlighting a specific area but could be a drawback in lamps or globes. In a few years, expect a cheaper, more versatile LED. Until then, experts recommend compact fluorescents (CFLs) for most home use—with a note of caution. Their mercury content calls for disposal as hazardous waste. —Linda Kulman

The average U.S. household produces about 150 pounds of CO2 a day by doing commonplace things like turning on air-conditioning or driving cars. That's more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses.
A gallon of gasoline adds a whopping 19.6 pounds of CO2 to the atmosphere, a big chunk of our daily allowance. A kilowatt-hour (kWh) of electricity in the U.S. produces 1.5 pounds of CO2. Every 100 cubic feet of natural gas emits 12 pounds of CO2.

5 Green Ways to Kick Back This Summer

A very cool young lady…

5 Green Ways to Kick Back This Summer

Olivia Bouler Young environmental activist

A kid's year pretty much revolves around summer vacation. Time stretches out, letting us explore the world in a way we can't when we've got homework, sports and music lessons. During the school year, rarely do we have the luxury to hang out under a tree, watching birds and butterflies flutter overhead. Nature has a positive effect on a person's well-being. There were many studies proving that sunlight in classrooms and offices promotes learning abilities, mood and overall performance. Nineteenth-century American writer Ralph Waldo Emerson recommended that people go into the woods to reset their inner compass. And would you believe there is even a syndrome called nature deficit disorder? Before summer slips away and you're packing up to head back to school, make sure you spend a little time in nature.
Here are five quick ways to get started.
One: For 15 minutes, go outside and unplug. Bring a novel or a field guide to read outside on the grass or even perched in a tree. Don't check your phone or emails --nothing is going to happen in 15 minutes! Sometimes I set a timer so I don't keep checking the time. After the first few minutes, I forget about everything going on, instead focusing on every sound I can hear. Then before long, a flock of doves passes by or a leaf flutters, something I would have never noticed if I had been distracted or busy. Even in the most busy urban neighborhood, you'll be surprised to find all sorts of birds, perhaps a falcon or two.
Two: Once I notice something exceptionally interesting, which occurs frequently in nature, I can't help but want to record it in some way. A notebook or sketchbook can be a place to write down what you saw, or make a quick sketch so you remember all the details. One of my favorite things to do when birding is to take pictures, since I often use my pictures as models for drawings down the road. Sometimes if I really like a picture, I load it as my desktop background so I can relive the moment.
Speaking of computers, another way to enjoy nature this summer is to check in with a nestcam. All around the country, birds are raising their chicks, getting them ready to leave the nest, and cameras have been set up so you can watch live on your computer. It's pretty awesome to see a great blue heron defend her nest from an owl, you know!
Three: Of course, nothing beats seeing birds in real life. To encourage birds to come to my yard, I keep bird feeders filled with seed, especially oiled sunflower seed. The birds hang out and sometimes I bring my lunch outside and eat with them. One experiment I did was charting which birds went to which feeders. I learned that some birds ate off the ground, while others liked only the feeders. One bird, a nuthatch, actually enjoys eating from the feeders upside down!
Four: My little brother Jackson has gotten into planting this summer. He's planted a vegetable garden for my mom, a butterfly bush to encourage butterflies to come to our yard and even native plants at the nature preserve. Like most nine-year-olds, he loves digging holes and getting dirty, but I can tell he also likes seeing the plants grow. One night we ate some of the lettuce he grew, but we are still waiting for tomatoes.
Five: If you get adventurous, think about asking your parents to take a hike with you. There are nature preserves and parks all over -- some may be closer to your town than you think. Not only do you get to enjoy nature, you'll be supporting conservation areas in your own community. Who knows -- you might even inspire your family to take an eco-vacation. Last summer I went to Costa Rica to visit the rainforest, and the year before that, I went to Maine to see the puffins.
Consider trying one of these ideas to bring a little nature into your summer. It's the perfect time of year to get outside and experience what's happening in your world. Who knows, it may just reset your inner compass!

Where Do All Those Facebook Photos Go?

Something I’ve never thought about while using Facebook or any other site…

Where Do All Those Facebook Photos Go?

On the outer boundaries of the Arctic Circle lies a massive construction project funded by Facebook: the future home of thousands of server farms

By Mark Strauss           Smithsonian magazine, July-August 2012
With 900 million members worldwide and growing, Facebook is building its first European data storage facility—60 miles south of the Arctic Circle in Lulea, Sweden. The reason: natural air conditioning. Some Internet “server farms” spend as much to cool the machines as power them. Facebook’s Nordic operation—which will eventually expand to three 290,000- square-foot buildings, each housing tens of thousands of servers—will save millions of dollars on electricity. Plus, the buildings are designed to capture some heat from the servers and use it to warm employee offices. The estimated cost of building the facilities is more than $700 million. Sweden hopes that construction subsidies and other incentives, including the promise of clean hydropower, will attract more digital companies to a region now being marketed as the “Node Pole.”

Tree Thursday - Silver Buttonwood

Silver Buttonwood
Conocarpus erectus var.sericeus

Silver buttonwood, a Florida native, is a variety of buttonwood that usually grows as a low branching shrub with several trunks, but under ideal conditions silver buttonwood can become a handsome vase-shaped tree up to 50 ft tall with a 20 ft  spread. The evergreen leaves are oblong to lance-shaped, 2-4 inches long and arranged alternately. Whereas typical buttonwood has glabrous (hairless) leaves, the leaves of silver buttonwood are covered with a dense mat of silky hairs which imparts a beautiful silver-gray color to the plant. The flowers are inconspicuous but the fruit clusters are rather showy brownish-red cone-like buttons, each containing many tiny fruits.
Buttonwood (whose wood is hard and without growth rings) was once an important source of charcoal in South Florida. It is said to be excellent for smoking fish and meat. Silver buttonwood, with its small, silver leaves and contorted trunk, is a favorite subject for bonsai.  http://www.floridata.com/ref/c/cono_ere.cfm


Growth Rate – Medium
Salt Tolerance – Extremely High
Drought Tolerance – High
Best planted in exposed area with good air flow to prevent mold on leaves.

5 Ways to Save Money on Air Conditioning

The average homeowner spends about $375 on air conditioning. Here's how to slash your summer energy bills, and still stay cool.

With a brutal heat wave spreading across the U.S., many people are turning on their air conditioners. The typical U.S. home spends 17% of its annual energy bill on cooling – about $375.
Summer is the time when electricity demand spikes, stressing the grid and pumping copious air pollution into the atmosphere. Emissions from coal-fired power plants, particularly, cooks in the summer sun to create smog and ozone pollution. (See 5 facts and myths about ozone pollution.)
These tips will help you reduce the amount of energy you pay for to run your air conditioner. How? You'll use it less, and use electricity more efficiently.

5 Ways to Save Money and Energy on Air Conditioning

So you already have an air conditioner, or you're planning to buy one... Save money and energy with the previous eight tips (after all, they'll help you use your AC less) plus these five maintenance and buying tips:
1. Adjust the thermostat
If you have central air controlled by a thermostat, use a programmable thermostat to save energy by increasing the heat significantly during the day when the house is empty. You can give up a couple degrees at night, too – especially on the hottest days. You may be surprised to find that the contrast between outdoor and indoor temperatures matters as much as the absolute temperature inside your home. When home, aim to set the temperature at 78 degrees to balance comfort with energy and cost savings. Together with winter energy savings, a programmable thermostat used properly can save the average home up to $150.
2. Clean the air filter
Whether you have central air or a room air conditioner, a dirty filter will reduce its efficiency, making it use more energy and cost more money to do the same job. Check your HVAC system's air filter monthly and expect to change the filter every three months.
3. Get an annual checkup
If you have central air, consider an annual checkup – once should cover both the heating and the cooling season. A professional should be able to diagnose any inefficiencies before you've wasted money on monthly heating and cooling bills.
4. Think small
Cooling one room with a window air conditioning unit requires much less energy (and investment) than a central air system. Ask yourself how you'll use your new air conditioner, and choose the smallest option that works. The government's Energy Star site has a handy guide to help you choose the right air conditioner for your space.
5. Buy Energy Star
Whether you're buying a central air conditioner (which could qualify for a tax credit) or a room unit, efficiency matters. An Energy Star central air system will use about 14% less energy than minimum government standards, and a room air conditioner will save at least 10%. Use the Energy Star Website before making a purchase, because while the vast majority of the 1,000-plus Energy Star window air conditioners barely meet the standards by using just 10% less energy than a standard model, some are clearly a better value. Compared to the typical, these nine models use at least 25% less energy:
