According to the Atlas of Florida Vascular Plants, there are more than 4,200 plant species naturally occurring in the state. Nearly 3,000 are considered native. The Florida Native Plant Society (FNPS) defines native plants as “those species occurring within the state boundaries prior to European contact, according to the best available scientific and historical documentation.” In other words, the plants that grew in natural habitats that existed prior to development.
Native plants evolved in their own ecological niches. They are suited to the local climate and can survive without fertilization, irrigation or cold protection. Because a single native plant species usually does not dominate an area, there is biodiversity. Native plants and wildlife evolved together in communities, so they complement each other’s needs. Florida ranks 7th among all 50 states in biodiversity for number of species of vertebrates and plants. Deer browse on native vines like Crossvine (Bignonia capreolata), Trumpet Creeper (Campsis radicans), Yellow Jessamine (Gelsemium sempervirens) and Trumpet Honeysuckle (Lonicera sempervirens). The seeds and berries of Black-eyed Susan (Rudbeckia fulgida), Flowering Dogwood (Cornus florida) and Dahoon holly (Ilex cassine) provide vital food for songbirds, both local and migratory. Saw palmetto (Serenoa repens) provides cover for numerous birds and small mammals, as well as, reptiles.
Non-native plants become “naturalized” if they establish self-sustaining populations. Nearly one-third of the plants currently growing wild in Florida are not native. While these plant species from other parts of the world may provide some of the resources needed by native wildlife, it comes at a cost to the habitat. These exotic plants can become “invasive”, meaning they displace native plants and change the diverse population into a monoculture of one species. Chinese privet (Ligustrum sinense), Popcorn trees (Triadica sebifera) and Cogongrass (Imperata cylindrica) have changed the landscape of Florida over the past decade. While Water hyacinth (Eichhornia crassipes) and Hydrilla (Hydrilla verticillata) have changed water flow in many rivers and lakes. These invasive species cost millions of taxpayer dollars to control.
By choosing to use native plants and removing non-native invasive plants, individuals can reduce the disruptions to natural areas. For more information one specific native plants that benefit wildlife go to: http://edis.ifas.ufl.edu/uw384

Early spring is a great time of year to reevaluate your lawn and landscape water needs. University of Florida studies have shown that in homes utilizing automatic sprinkler systems, 50% of total home water consumption in the summer comes from running a sprinkler system. When a homeowner is using utility water, they are typically charged twice; first for bringing the water in and second for wastewater fees. Estimated costs for irrigating a 5,000 square foot yard range from $5-$25 per irrigation session. So how does one cut down?
To start with, check your sprinkler system for efficiency. Turn on the water, stand back, and watch it run. Look for broken or clogged heads (evident by uneven and high-volume spray), or leaks within the water line. Clean out the heads or replace these broken parts—most are very inexpensive and found in the plumbing section of home improvement stores. Look at the reach of the spray, and make sure irrigation water is not landing wastefully on roads, sidewalks, or adjacent houses. To paraphrase a wise colleague, “No matter how much you water it, concrete won’t grow.”
Many of our clientele ask how long an irrigation system should be run and how much water plants should get. Ideally, turf and landscape plants should get ½” to ¾” of water per application. The frequency of application varies by plant needs, weather, and soil type. For very sandy soils, some specialists have recommended applying less water at a slightly more frequent rate, since sandy soils are unable to hold water in the root zone of plants for long. Mulching around plants and amending soils with organic material can help improve a soil’s water-holding capacity.

A simple sprinkler calibration can be conducted by spreading empty aluminum cans around one’s yard, and turning on each sprinkler zone. Run each zone for 30 minutes and measure how deep the water is in the cans. If the water depth is within the recommended amounts, no changes are needed. However if it’s not deep enough or greater than ¾” of an inch, run times should be adjusted accordingly. If some of the cans receive a noticeably different amount of water than those adjacent to them, it is a signal that the reach of the spray heads is not adequately set and should be corrected to make sure the entire landscape has even coverage.
The primary goal of supplemental irrigation is for the plants’ root zones to be wet, but not saturated or too dry. Ideally, established lawns and landscapes should thrive on rainfall after initial establishment, and only take irrigation in longer periods of drought. However, this is contingent on the planting of Florida-friendly vegetation and a homeowner with a keen eye to the condition of one’s plants, who is willing to turn the sprinkler system to “manual” and wait for his or her plants to start drooping before turning on the water. In reality, most homeowners find it difficult to take this much time and care with their irrigation system, and opt for the “water every two or three days whether needed or not” approach, even in parts of the state with water restrictions. In fact, anecdotal evidence seems to show that homeowners only allowed to water lawns one or two days a week will overdo it just to make sure their plants survive.
Luckily, new technology exists that can take the guesswork out of irrigation for a homeowner, while keeping plants alive and conserving water at the same time. “Smart” irrigation systems include soil moisture sensors and evapotranspiration (ET) controllers. Soil moisture sensors (SMS) use electrodes buried within the root zone of turf, which are calibrated to a certain level of moisture in the soil. The system is only allowed to run when water levels drop below a preset threshold. ET (evapotranspiration) controllers monitor weather conditions on site or from a nearby weather station, using satellite signals to determine when plants will need additional water.

With all the news about the Zika virus spread in Florida, now is the time to start thinking about mosquito protection. As the weather warms, they will be hatching. Check out where the water is collecting in your yard. The female Aedes aegypti mosquitoes lay their eggs in temporary flood water pools; even very small ones such as pet watering bowls, bird baths and upturned Magnolia or Oak leaves. Dumping out the collection containers and raking through the leaves every couple of days can greatly reduce the population.
Becoming infected with Zika virus is not common. Though the disease can be transmitted by mosquitoes, blood transfusions or sex, the only know infections in Florida were from people who had been “bitten” by mosquitoes while travelling to countries with active virus outbreaks. That is until this past week, when a person-person infection occurred between a man that had been infected while out of the country and the woman he returned to in Florida. Mosquitoes usually obtain the virus by feeding on infected people, who may not exhibit any symptoms because they have been exposed and their body has built an immunity to the virus. Once the mosquito has drawn infected blood from the person, the infected mosquito “bites” another human, transmitting the virus mixed in saliva into the blood stream of the second host. If the second host is a susceptible pregnant woman, there is a risk of birth defects for the unborn child. If the infected host is a man, he can transmit the virus in semen for about two weeks.
Government public health officials here in Florida are able to monitor mosquito-borne illnesses quickly and effectively. Though the daily news can be alarming, the awareness is truly the message.
To protect yourself and reduce the sources for mosquitoes to breed, here are a few pointers:
Stay indoors at dusk (peak mosquito biting time).
If you must be outside, wear long sleeves and pants and/or mosquito repellents containing the active ingredient DEET.
Repair torn door and window screens.
Remove unnecessary outside water sources.
Flush out water collected in outdoor containers every 3-4 days.
Disturb or remove leaf litter, including roof gutters and covers on outdoor equipment.
Apply larvicides, such as Bacillus thuriengensis israelensis (BTI) to temporary water holding areas and containers.
The mosquitoes have been around all winter with the milder weather and frequent rain. As spring approaches they will be laying eggs on all the water surfaces they can find. As you venture out into the yard or travel to the great outdoors, remember to protect yourself and look at all the ways you can remove the potential habitats for the pesky creatures.

The best time to plant a tree is twenty years ago. The second best time is for Arbor Day. Florida recognizes the event on the third Friday in January, but planting any time before spring will establish a tree quickly.
Arbor Day is an annual observance that celebrates the role of trees in our lives and promotes tree planting and care. As a formal holiday, it was first observed on April 10, 1872 in the state of Nebraska. Today, every state and many countries join in the recognition of trees impact on people and the environment.
Trees are the longest living organisms on the planet and one of the earth’s greatest natural resources. They keep our air supply clean, reduce noise pollution, improve water quality, help prevent erosion, provide food and building materials, create shade, and help make our landscapes look beautiful. A single tree produces approximately 260 pounds of oxygen per year. That means two mature trees can 
supply enough oxygen annually to support a family of four.
The idea for Arbor Day in the U.S. began with Julius Sterling Morton. In 1854 he moved from Detroit to the area that is now the state of Nebraska. J. Sterling Morton was a journalist and nature lover who noticed that there were virtually no trees in Nebraska. He wrote and spoke about environmental stewardship and encouraged everyone to plant trees. Morton emphasized that trees were needed to act as windbreaks, to stabilize the soil, to provide shade, as well as, fuel and building materials for the early pioneers to prosper in the developing state.
In 1872, The State Board of Agriculture accepted a resolution by J. Sterling Morton “to set aside one day to plant trees, both forest and fruit.” On April 10, 1872 one million trees were planted in Nebraska in honor of the first Arbor Day. Shortly after the 1872 observance, several other states passed legislation to observe Arbor Day. By 1920, 45 states and territories celebrated Arbor Day. Richard Nixon proclaimed the last Friday in April as National Arbor Day during his presidency in 1970.
Today, all 50 states in the U.S. have official Arbor Day, usually at a time of year that has the correct climatological conditions for planting trees. For Florida, the ideal tree planting time is January, so Florida’s Arbor Day is celebrated on the third Friday of the month. Similar events are observed throughout the world. In Israel it is the Tu B Shevat (New Year for Trees). Germany has Tag des Baumes . Japan and Korea celebrate an entire week in April. Even, Iceland one of the treeless countries in the world observes Student’s Afforestation Day.
The trees planted on Arbor Day show a concern for future generations. The simple act of planting a tree represents a belief that the tree will grow and some day provide wood products, wildlife habitat erosion control, shelter from wind and sun, beauty, and inspiration for ourselves and our children.
“It is well that you should celebrate your Arbor Day thoughtfully, for within your lifetime the nation’s need of trees will become serious. We of an older generation can get along with what we have, though with growing hardship; but in your full manhood and womanhood you will want what nature once so bountifully supplied and man so thoughtlessly destroyed; and because of that want you will reproach us, not for what we have used, but for what we have wasted.”
~Theodore Roosevelt, 1907 Arbor Day Message

TELL ME NO! Please tell me these huge spiders are not a part of our summer. People are afraid snakes… that’s a given – but there are just as many afraid of spiders. Honestly, after years of leading field hikes into the north Florida environment, when we encounter a spider web on the trail I have heard more screams from the boys than from the girls. But most are afraid and there nothing is more terrorizing than the huge, almost hand-size, Golden Orb Weaver (or banana spider).
The Golden Orb Weaver is one of 180 species of orb weavers from around the world; one from Australia is large enough to feed on small birds. The local species is Nephila clavipes and is found throughout the southeastern United States; in the warmer months it may reach as far north as New England. Female Orb Weavers are the really big ones you find on the webs. Their body lengths can reach 2” (not including the extended legs) and the males are much smaller at 0.02”. They have long inward pointing legs with hair-like tuffs at the joints. These are very useful in web building. They have the typical “red/yellow/black” coloration of a venomous animal and their mimics; but N. clavipes is no mimic… though mild, they do have venom. There is another orb weaver spider that is large a constructs large webs. This is the Black and Yellow Argiope (Agriope aurantia). One way to distinguish this spider from the Golden Orb is the “zig-zag” pattern it adds to its’ web near the center (where the spider spends a lot of its time).

The name “Golden Orb” does not come from their body coloration but from the color of the silk produced for their webs. It is believed that the yellow/golden color of this silk makes it difficult for others to see in open sunny areas. Many hikers can attest to this… they are hard to see, until you become entangled… then become aware the large spider is very close and heading your way… then the scream. N. clavipes can actually adjust the hue of yellow in the silk to match the sunlight conditions where it is building its web. It is amazing to see how quickly they replace their large webs, over 3 feet in diameter, after they have been removed by people. Actually they mend and move their webs regularly. They tend to build them off ground, at eye level to the tree tops, in open areas near a line of trees. I have actually seen one build the web across a dirt road between two stands of pines as if it were going to try and capture a truck! Though species of Orb Weavers feed on small birds and snakes, N. clavipes prefers flying insects. They do not wrap their prey in silk for later feeding, as many spiders do, but rather consume them almost immediately. This may be because of a small slivery spider called Argyrodes. This spider feeds on the captured food of other spiders. N. clavipes feeding may be an adaptation to combat this kleptoparasitic spider. Another interesting behavior I have noticed is when the heavy rains come. I have noticed the web remains but the spiders leave. I am not sure where they go, most likely a hiding spot nearby, but they do leave.
The fear of spiders is most likely similar to the fear of snakes… they are venomous. Venom is used to kill prey and many times is not strong enough to kill humans, but the fact that some species can kill makes folks a bit nervous. Despite local tales that say otherwise, the venom of N. clavipes is mild. It is a neurotoxin, which can be potent, but the bite from this spider is not lethal. The typical response is pain and redness at the site of the bite, blisters may form, but it is actually less potent than a bee sting.
Like many other species of spiders, the Golden Orb Weaver is a beneficial backyard creature consuming hundreds of biting (in some cases disease carrying) insects. The large webs can be a nuisance around backyard patios and swimming pools but they can easily be moved to other locations with a rake or broom. We have many of them in our yard, one out of my office window, and enjoy watching them work. They are good panhandle neighbors.
