Exclusion Cage in food plot with normal deer feeding.
When we talk about white-tailed deer management, we often look to the states that have monster deer like Iowa, Illinois, and Ohio. Those states grow 200 plus inch bucks. It’s amazing to see for sure. But this is Florida and we can’t effectively manage deer the same way. Actually, in Florida, we can’t even manage deer the same across the state. This is why we have 12 deer management units. So, what are the reasons we can’t manage deer the same?
Habitat
Plant hardiness and climate
Rut timing
Deer are highly adaptable to habitats. They can be found in almost every state in the US. The native vegetation is very different in Northwest Florida versus Iowa or Illinois. Deer are eating different diets depending on the habitat they are residing in. Bedding areas will vary also. This affects the body size, antler growth, and fawning rates for deer.
We can grow food plots to supplement deer diets but those will look a little different too. For example, clovers and cereal grains are normally frost seeded in late winter or planted in the spring in parts of the country that actually experience winter. In Northwest Florida, we plant clovers and cereal grains in the fall.
Finally, rut timing is a key part of deer nutrition management. In Northwest Florida, the rut (deer breeding season) is happening now. In other parts of the country such as Iowa, they are shed hunting already because their rut happens in November.
So, given these reasons, we do things a little differently here. We plant cool season food plots in the fall. These act as attractants to draw deer in during hunting season. Then our summers are when the deer need more nutrition for antler growth and fawn rearing. Warm season food plots should focus on supplying adequate crude protein and energy for this increased demand period.
Spring can be a busy time of year for those of us who are interested in improving wildlife habitat on the property we own/manage. Spring is when we start many efforts that will pay-off in the fall. If you are a weekend warrior land manager like me there is always more to do than there are available Saturdays to get it done. The following comments are simple reminders about some habitat management activities that should be moving to the top of your to-do list this time of year.
Aquatic Weed Management – If you had problematic weeds in you pond last summer, chances are you will have them again this summer. NOW (spring) is the time to start controlling aquatic weeds. The later into the summer you wait the worse the weeds will get and the more difficult they will be to control. The risk of a fish-kill associated with aquatic weed control also increases as water temperatures and the total biomass of the weeds go up. Springtime is “Just Right” for Using Aquatic Herbicides
Cogongrass Control – Spring is actually the second-best time of year to treat cogongrass, fall (late September until first frost) is the BEST time. That said, ideally cogongrass will be treated with herbicide every six months, making spring and fall important. When treating spring regrowth make sure that there are green leaves at least one foot long before spraying. Spring is also an excellent time of year to identify cogongrass patches – the cottony, white blooms are easy to spot.

Warm-Season Food Pots – There is a great deal of variation in when warm season food plots can be planted. Assuming warm-season plots will be panted in the same areas as cool-season plots, the simplest timing strategy is to simply wait for the cool-season plots to play out (a warm, dry May is normally the end of even the best cool-season plot) and then begin preparation for the warm-season plots. This transition period is the best time to deal with soil pH issues (get a soil test) and control weeds. Seed for many varieties of warm-season legumes (which should be the bulk of your plantings) can be somewhat hard to find, so start looking now. If you start early you can find what you want, and not just take whatever the feed store has. Warm Season Food Plots for White-tailed Deer
Deer Feeders – Per FWC regulations deer feeders need to be in continual operation for at least six months prior to hunting over them. Archery season in the Panhandle will start in mid-October, meaning deer feeders need to be up and running by mid-April to be legal to hunt opening morning. If you have plans to move or add feeders to your property, you’d better get to it pretty soon. FWC Feeding Game
Dove Fields – The first phase of dove season will begin in late September. When you look at the “days to maturity” for the various crops in the chart below you might feel like you’ve got plenty of time. While that may be true, don’t forget that not only do you need time for the crop to mature, but also for seeds to begin to drop and birds to find them all before the first phase begins. Because doves are particularly fond of feeding on clean ground, controlling weeds is a worthwhile endeavor. If you are planting on “new ground”, applying a non-selective herbicide several weeks before you begin tillage is an important first step to a clean field, but it adds more time to the process. As mentioned above, it’s always pertinent to start sourcing seed well in advance of your desired planting date. Timing is Crucial for Successful Dove Fields
There are many other projects that may be more time sensitive than the ones listed above. These were just a few that have snuck up on me over the years.

Landowners frequently prioritize wildlife abundance and diversity in their management goals. This is often related to a desired recreational activity (hunting, bird watching, etc.).
In order to successfully meet wildlife related management goals, landowners need to understand that animals frequent specific areas based largely on the quantity, quality and diversity of the food and cover resources available. Implementing management strategies that improve wildlife habitat will lead to greater wildlife abundance and diversity.
Herbivorous wildlife feed on plants, mostly in the form of forages and mast crops. All wildlife species have preferences in terms of habitat, especially food sources. Identifying these preferences and managing habitat to meet them will promote the abundance of the desired species.
Herbaceous plants, leaves, buds, etc. – serve as forages for many wildlife species. Promoting their growth and diversity is essential for improving wildlife habitat. Three common habitat management practices that promote forage growth include:
1) Create forest openings and edges; forested areas with multiple species and/or stand ages, areas left unforested allowing for increased herbaceous plant growth.
2) Thinning; open forest canopy allowing more light to hit the ground increasing herbaceous plant growth and diversity.
3) Prescribed fire; recycle nutrients, greatly improve the nutritional quality of herbage and browse, suppress woody understory growth.
Mast – the seeds and fruits of trees and shrubs – is often one of the most important wildlife food sources on a property.
Hard mast includes shelled seeds, like acorns and hickory nuts and is generally produced in the fall and serves as a wildlife food source during the winter.
Soft mast includes fruits, like blackberries and persimmons, and is generally produced in the warmer months, providing vital nutrition when wildlife species are reproducing and/or migrating.
Making management decisions that protect and promote mast producing trees will encourage wildlife populations.
Landowners can make supplemental plantings to increase the quantity and quality of the nutrition available to wildlife. These supplemental plantings (food plots/forage crops and mast producing trees) can be quite expensive and should be well planned to help maximize the return on investment.
Key points to remember to help ensure the success of supplemental wildlife plantings.
Select species/varieties that are well adapted to the site.
Take soil samples and make recommended soil amendments prior to planting.
Make plantings in areas already frequented by wildlife (edges, openings, etc.).
Food plots should be between 1 and 5 acres. Long, narrow designs that maximize proximity to cover are generally more effective.
Habitat management and other wildlife related topics are being featured this year in the UF/IFAS building at the Sunbelt Ag Expo. Make plans to attend “North America’s Premiere Farm Show” and stop by the UF/IFAS building, get some peanuts and orange juice and learn more about Florida’s Wildlife.

It’s that time of year when landowners, hunters, and other wildlife enthusiasts begin to plan and prepare fall and winter food plots to attract wildlife like the nice buck in the photo.
Annual food plots are expensive and labor intensive to plant every year and with that thought in mind, an option you may want to consider is planting mast producing crops around your property to improve your wildlife habitat. Mast producing species are of two types of species, “hard mast” (oaks, chestnut, hickory, chinkapin, American Beech, etc.), and “soft mast” (crabapple, persimmon, grape, apple, blackberry, pears, plums, pawpaws, etc.). There are many mast producing trees and shrubs that can be utilized and will provide food and cover for a variety of wildlife species. This article will focus on two, sawtooth oak (or other oaks) and southern crabapple.
Sawtooth Oak
Oaks are of tremendous importance to wildlife and there are dozens of species in the United States. In many areas acorns comprise 25 to 50% of a wild turkeys diet in the fall (see photos 1, 2, and 3) and probably 50% of the whitetail deer diet as well during fall and winter. White oak acorns average around 6% crude protein versus 4.5% to 5% in red oak acorns. These acorns are also around 50% carbohydrates and 4% fat for white oak and 6% fat for red oak.
The Sawtooth Oak is in the Red Oak family and typically produces acorns annually once they are mature. The acorns are comparable to white oak acorns in terms of deer preference as compared to many other red oak species. Most red oak acorns are high in tannins reducing palatability but this does not seem to hold true for sawtooth oak. They are a very quick maturing species and will normally begin bearing around 8 years of age. The acorn production at maturity is prolific as you can see in the photo and can reach over 1,000 pounds per tree in a good year when fully mature. They can reach a mature height of 50 to 70 feet. There are two varieties of sawtooth oak, the original sawtooth and the Gobbler sawtooth oak, which has a smaller acorn that is better suited for wild turkeys. The average lifespan of the sawtooth oak is about 50 years

Southern Crabapple
Southern Crabapple is one of 25 species of the genus Malus that includes apples. They generally are well adapted to well drained but moist soils and medium to heavy soil types. They will grow best in a pH range of 5.5 – 6.5 and prefer full sun but will grow in partial shade as can be seen in photo 4. They are very easy to establish and produce beautiful blooms in March and April in our area as seen in photo 5. There are many other varieties of crabapples such as Dolgo that are available on the market in addition to southern and will probably work very well in north Florida. The fruit on southern crabapple is typically yellow green to green and average 1 to 1.5 inches in diameter. They are relished by deer and normally fall from the tree in early October.

I know it feels too hot outside to talk about hunting season or cool-season food plots, but planting time will be here before you know it and now’s the time to start preparing. The recommended planting date for practically all cool-season forage crops in Northwest Florida is October 1 – November 15. Assuming adequate soil moisture, planting during the first half of the range is preferred. Between now and planting time there are several factors that need to be considered and addressed.
Invasive and/or Perennial Weed Control – Deer and other wildlife species utilize many soft/annual “weeds” as forage so controlling them is usually not a major concern. But from time to time unwanted perennials (grasses and woody shrubs) need to be controlled. An unfortunate and all too common example of and unwanted perennial is cogongrass – a highly invasive grass that should always be controlled if found. Effective control of perennial weeds, like cogongrass generally involves the use of herbicides. Late summer/early fall is a very effective time to treat unwanted perennials. Fortunately, this coincides well with the transition between warm-season and cool-season forages. If you have unwanted, perennial weeds in your food plots get them identified now and controlled before you plant your cool-season forages.

Soil Fertility Management – In my experience, the most common cause for poor plant performance in food plots is inadequate soil fertility. Before planting time collect and submit soil samples from each of your food plots. Laboratory analysis of the samples will let you know the fertilizer and lime requirements of the upcoming cool-season crop. It is very important to have the analysis performed prior to planting so performance hindering issues can be prevented. Otherwise, during the growing season, by the time you realize something is wrong, it will likely be too late to effectively address the problem. This is particularly true if the issue is related to soil pH. To affect soil pH in a timely manner lime needs to be incorporated into the soil. Incorporation is impossible after the new crop has been planted. Soil analysis performed at the University of Florida’s Extension Soil Testing Lab cost $7 per sample. Your county’s UF/IFAS Extension Agent can assist you with the collection and submission process as well as help you interpret the results.
Variety Selection & Seed Sourcing – Sometimes it takes some time to find the best products/varieties. Just because forage seeds are sold locally doesn’t mean that the crop or specific variety is well suited to this area. The high temperatures and disease pressure associated with Florida, even in the “cool-season” mean that many products that do very well in other parts of the country may struggle here. Below are some specific forages that are favored by wildlife (specifically white-tailed deer) and generally well adapted to Florida. You may discover that these varieties are not sitting on the shelf at the local feed & seed. Often local suppliers can get specific varieties, but they must be special ordered, which adds time to the process. Hence the need to start planning and sourcing seed early.
If you are debating trying food plots on your property for the first time, please carefully consider the following. Food plots are not easy – Making productive food plots that provide a measurable, positive impact to the wildlife on your property takes considerable time, effort, and money. Considering this, food plots really only make sense when viewed as habitat improvements that provide long term benefits to multiple wildlife species. If you are looking for nothing more than a deer attractant during hunting season food plots are not a very practical option. For more information on getting started with food plots contact your county’s UF/IFAS Extension Office and check out the reference below.
