Attracting wildlife is one of the Florida Friendly Landscaping principles. However, some species are better observed from long distance. Deer are beautiful creatures and taste pretty good too, but they can wreak havoc to a landscape and to fruits and vegetables. There are a number of methods to deter deer, but you’ll need to keep them guessing to limit damage to your yard.

Physical Barriers – This deterrent method may be the most effective if installed correctly, but it can also be costly and requires the most labor and engineering to install.
Temporary Deer Fencing – Plastic mesh fencing can temporarily keep deer away from plantings. This material can be draped over plants or attached to posts or fencing with plastic ties or wire.
Hardware Cloth and Seedling Tubing – Hardware cloth can be formed into different shapes or secured to small structures to form a barrier around small plants. UV-inhibited polyethylene and polypropylene mesh seedling tubes can be bent into cylinders and placed around young shrubs and trees to protect them from foraging deer and other wildlife.
Garden Fencing – There are a variety of gauges available for this fencing. Heavier gauges are recommended to help keep deer out. It’s important to note that most adult deer can jump 7 feet high, so a fence height of at least 8 feet is recommended.
Electric Fencing – Peanut butter can be spread on a single strand of electric wire to encourage deer to check it out. More permanent electric fences can be installed, but are significantly more expensive.
Scare Items – Deer are skittish to things that are unfamiliar to them. However, it doesn’t take them long to adapt.
Ribbons and Tape – Light-weight ribbons and tape fluttering in the wind can help deter deer. Holographic and iridescent foil materials have shown the best results because they reflect sunlight and create more noise in the wind.
Motion Activated Sprinklers – Hitting a deer directly and the sound of water being turned on are deterrents for deer and other wildlife. It is best to periodically move the location of these sprinklers to improve their effectiveness.
Noisemakers – Whistles, firecrackers, and propane cannons can annoy deer, and people too. Unfortunately, deer become accustomed to these tactics. It is best to use noisemakers in combination with other deterrent methods.
Dogs – Just having a dog around can help keep deer away. Even if it’s a dog that has no care to bark at or chase a deer, its scent alone may be enough to deter them.

Chemical Repellents – A plethora of chemicals are marketed as deer deterrents. These products can work as odors, create bad tastes, or incite fear. Common ingredients include capsaicin, predator urine, egg solids, garlic, and soap. A number of factors can contribute to the effectiveness of chemical repellents including the growth stage of the plants to be protected and frequency of reapplication,
Resistant Plants – Deer eat almost anything. They sometimes even eat so-called “deer resistant plants”. However, the plants listed below are less desirable to deer. For a more comprehensive list of plant susceptibility to deer damage please visit the archived publication “Ornamental plant susceptibility to damage by deer in Florida”.
Trees – Deer will rub on almost any tree, but a few they are less likely to eat include: bottlebrush, sabal palm, crape myrtle, edible fig, loquat, live oak, magnolia, and yaupon holly.
Shrubs – Some shrubs that deer are less likely to eat include: mahonia, viburnum, wax myrtle, juniper, and most evergreen azaleas.
Annuals and Perennials – There are quite a few annuals and perennials that have shown signs of resistance to deer including: black-eyed Susan, bush daisy, cone flower, dusty miller, marigold, and salvia.
UF IFAS Extension Escambia County was recently able to offer a native tree and shrub giveaway to our community. A county partner had some grant funding remaining and chose a nice selection of plants grown by a local native nursery. After seeing the plant selection, I was really excited that a few participating homeowners had the opportunity to take home one of my favorite native plants, the Sparkleberry, Vaccinium arboretum.

Twenty-three years ago, I saved a sparkleberry on my new home lot because I loved this native tree. It has interest in all seasons in my opinion, including flowers, small fruit for wildlife, attractive bark, and an interesting shape as it matures. It has been a slower growing tree than others in my yard but I have enjoyed watching the tree develop its form and the bark develop the beautiful flaky cinnamon-brown look.

The small tree is now about 12 feet tall and has never had any issues in the sandy, well drained soil. It can tolerate some moisture as long as the soil drains well. A grouping of trees from my neighbor’s lot keeps the plant in partial shade and we can often find sparkleberry specimens in the filtered light of woods. It can tolerate a sunnier location if that is the spot you have available for a small tree.
In addition to our enjoyment of this native tree, pollinators and other animals will appreciate the flower nectar, pollen, and berries. If you have a native nursery close to your home, be sure to ask for your own Sparkleberry if your site is suitable.
Many different Florida wildlife pass through a home landscape daily in search of food. Possibly the most destructive animal to landscape plants in northwest Florida is the White-Tailed Deer. Extensive amounts of damage can be observed after they have passed through. This damage is not just to landscapes but also impacts agriculture crops at an economic level.

Deer are searching for protein that can be found in many forms that may include acorns from oak trees, ornamental shrubs, flowers, and soybeans. For this article, I will focus on landscape plants. Deer require a significant amount of forages as adults to amass 6 plus pounds per 100 pounds of body mass on a daily basis as they attain muscle and fat. Maintaining this level of growth is needed for quality reproductive rates and surviving the times of year, usually the winter, with less food available. Keep in mind damage is significantly lower from mid-spring to mid-summer with greater damage occurring from late-summer to late-fall.

How to make informed plant decisions before placing them in the landscape and protecting many of these plants is a big question. There are many articles out there on selecting plants that are deer resistant or tolerant. Resistant to deer browsing is often dependent on how hungry they are and the amount of availability of other plants they prefer near by out of your landscape. With deer populations increasing significantly over the last few decades it has increased contact with people and the environments in which we live. To deter feeding and other damage to the landscape, fences have been placed as barriers, offensive smelling sprays have been used, lights and sounds have been used. The attempt is to offend more than one of the deer senses. These tactics work for a while until they adjust to these events and find their way back.

Some of the favored plants for deer include hosta, daylily, holly, and maple leaves and many more. Plants they tend to avoid are poisonous plants that include foxglove, poppies or fragrant plants from sage, salvias and bearded iris. There are publications with extensive lists of plants not to plant as they are a preferred food for deer and much shorter lists of plants they do not prefer. Contact your local UF IFAS Extension office for more information.
Deer, like many of the wildlife, were able to acclimate to neighborhoods and traffic settings. This has created additional dangers for many wildlife animals and people. The point is they are an established part of our communities. Determining how to best manage these growing populations has and will continue to be a big topic of discussion from neighbor to neighbor, community boards, farmers, and the Florida Wildlife Commission.
Sometimes we just need a little privacy. This is especially true if you live on a busy road or just have annoying neighbors. There are a few things to consider when selecting a screen tree: 1) full-grown size; 2) speed of growth; and 3) aesthetics. With these three factors in consideration, let’s review some screen options for different situations.

Pineapple Guava (Acca sellowiana)
At one time this shrub was hard to find, but it is slowly becoming more available. Pineapple guava is native to South America, but it adapts well to the Florida Panhandle. This plant can reach 10 to 15 feet in height with an equal spread and has a moderate rate of growth, so it’s a great choice when you just need a small screen. Pineapple guava is moderately salt-tolerant and does well in coastal landscapes. As a bonus, the flowers and fruit are edible. It’s hard to find a more aesthetically pleasing large shrub. Pineapple guava is evergreen with leathery green leaves that have grey undersides. This plant can be grown as a large shrub or pruned to be a small tree.

‘Emily Bruner’ Holly (Ilex x ‘Emily Bruner’)
‘Emily Bruner’ holly is a cross between the Chinese holly (Ilex cornuta) and the lusterleaf holly (Ilex latifolia). This evergreen shrub has glossy green leaves. It has a pyramidal growth habit and is listed as reaching 15 to 20 feet tall by 5 to 8 feet wide, however the specimen at the Santa Rosa County Extension Office is about twice that size. ‘Emily Bruner’ holly prefers moist, well-drained soil. This holly has dense, prickly leaves so it does well keeping people out of your yard in addition to buffering sound. The flowers have a sweet scent and are a favorite of honey bees.

Dahoon Holly (Ilex cassine)
Dahoon holly is native to North America, is tolerant of wet, shady sites (but can also handle full sun), and displays some salt tolerance. This evergreen, small tree is somewhat shrubby. It can grow to be 25 to 30 feet in height with an 8 to 12 foot spread. Dahoon holly has nice light green leaves that are smooth, not prickly like ‘Emily Bruner’ holly. It has a moderate growth rate.

Southern Magnolia (Magnolia grandiflora)
It’s hard to beat a majestic southern magnolia in the landscape. Why not utilize it as a screen tree? Now, not all southern magnolias are made equal. There are a few cultivars that do well as screens as well as on their own. ‘Bracken’s Brown Beauty’, ‘Claudia Wannamaker’, and ‘D.D. Blanchard’ are three that come to mind and are readily available in the trade. Southern magnolias can reach up to 80 feet tall and 20 to 40 feet wide depending on cultivar and growing conditions. Not only do these three cultivars have beautiful dark green, leathery leaves, their leaves also have brown undersides. These versatile trees can tolerate are variety of soil conditions and they are very wind resistant. And as another bonus, they have beautiful, fragrant flowers.

Eastern redcedar (Juniperus virginiana)
If your looking for softer texture in your landscape, then you can’t go wrong with a cedar tree. Unbeknownst to its name, eastern redcedar can be found growing all over the United States. This evergreen conifer prefers well-drained sites in full sun. It can grow 30 to 40 feet in height by 10 to 20 feet wide. Eastern redcedars have good salt tolerance. These trees produce beautiful, blue-green foliage. One key to growing this tree successfully is to give it space. Plant trees 12 to 24 feet apart. If using as a screen, you may consider staggering this tree to give it the space it needs.
There are lots of good options when selecting trees for a screen. It’s important you select plants that fit the site. The University of Florida has an excellent plant selection tool found at the Florida Trees for Urban and Suburban Sites webpage.
Anyone spending any time outdoors in the Florida panhandle is bound to come across some of our local scaly residents before too long. With our high temperatures, high humidity, and high number of insects, we have a great climate for numerous reptiles to survive in. Some are native, some are not, and it can help to learn a little about them to understand the ecology we live in.
Here are some of the most common lizards you’ll see in our area:
Anoles
One of the most commonly seen lizards around, the green anole (Anolis carolinensis), is native to Florida. While it is named ‘green’, it is able to change color from green to brown. Despite this ability to camouflage themselves, they are not related to chameleons. Often active during the day, they eat a wide range of insects and other arthropods. Males can often be seen doing push-ups and flashing their dewlaps (colorful neck-flaps) as either a deterrent to predators or to attract a mate. This species favors living in trees, but can be found almost anywhere. These and many other lizards have the ability to lose their tails when pursued by predators. The tail may continue to move for some time after it detaches, which can serve as a distraction while the lizard itself flees from danger. The tail will regrow over a period of time.
A similar species is threatening our native populations of anoles. The brown anole (Anolis sagrei), also known as the Cuban brown anole, is highly invasive. They differ from the green anole in that they cannot change color, and often display a bold pattern on their skin. Introduced to the United States as stowaways on ships in the late 1800s, they compete with native species for food and sometimes even eat young green anoles. Brown anoles are typically found near the coast in the panhandle. While control of this invasive species is probably impossible at this point, you can help to avoid spreading them by cleaning equipment they may hide in (trailers or boats, for example) before transporting it, and inspecting ornamental plants for hidden anoles before moving them.
Skinks
At least two species of skinks share our habitat, the five-lined skink (Plestiodon fasciatus) and the broadhead skink (Plestiodon laticeps). The five-lined skink is mostly black with colorful accents, usually having a reddish head and blue tail. White or off-white stripes run lengthwise down their body. They are found in almost any habitat, and eat insects and other arthropods. The blue tail does not indicate any ability to sting, despite some local folklore.
The broadhead skink is one of the largest lizards in the area, growing up to a foot in length. Colored similarly to the five-lined skink, mature males fade in color and develop large, reddish heads with powerful jaws. They use these jaws to eat insects, invertebrates, and probably other small animals as well. Broadhead skinks prefer living in trees, but can be seen on the ground occasionally as well.
Fence Lizards
Sceloporus undulatus, the eastern fence lizard, loves dry, open woodlands. They often flee for higher ground when scared, climbing trees, stumps, or fences for protection from predators. Fence lizards have rough scales, usually patterened along their backs, with males sometimes displaying blue patches on their undersides. They, like other lizards, eat insects.
Geckos
Not native but commonly seen, the Mediterranean gecko (Hemidactylus turcicus) is a nocturnal species that is found throughout Florida. Urban and suburban locations are their favored habitats. They are often attracted to artificial lights at night, or rather the insects that themselves are attracted to the lights. Mediterranean geckos are usually pale in coloration, with almost translucent white or grey skin. They have large eyes with slit pupils and wide pads on their feet, which help them stick to smooth surfaces.
Glass Lizards
Upon first sight, one might be forgiven for thinking that a this species is actually a snake. It is not. Ophisaurus ventralis, the Eastern glass lizard, is a species of legless lizard that can grow to more than three feet in length. They hunt for insects to eat during the day, but are shy and will quickly try to hide if confronted. They are quick to shed their tails when in danger from predators; their name refers to their being perceived as brittle and breaking easily, like glass. They are not venomous, and their jaws are not powerful enough to break human skin.
