To the chagrin of hunters across the panhandle deer season has drawn to a close. As the days lengthen and temperatures begin to climb, many of the area’s outdoorsmen (and women) shift their focus to a more aquatic nature. However, those sportsmen, who will place a premium on antler size in the fall, should not neglect the nutritional needs of the deer herd during the spring and summer months.

There is a well-documented correlation between deer nutrition and antler growth. Antler growth is suppressed when adequate nutrition is not available. Antler growth requires a large amount of energy and protein. The energy requirements for antler growth can generally be met by the deer’s natural environment. However, some natural environments may not supply enough protein to maximize antler growth. Nutrition is only one of several factors effecting antler growth but it is perhaps the easiest of those factors to alter.

As with all animals, a deer’s nutritional demands change over time. The suppressing effect of insufficient protein in the diet is most evident in younger bucks. This is because the bodies of immature deer are still growing. The processes of growth and development demand protein. When antler growth is added to the equation the protein demand of a young buck can easily exceed what is provided by it natural environment. Research indicates that young, growing deer during antler development need a diet that is approximately 16% crude protein in order to maximize antler growth. Mature bucks can maximize antler growth with as little as 10% crude protein.

Planting and maintaining warm season food plots is a good way for a deer herd manager to help prevent any nutritional limitations to antler growth. Food plots are often thought of in terms of their ability to attract deer to a specific location during hunting season. However, if properly utilized food plots can have a lasting positive effect on an area’s deer herd and other wildlife. Follow the links for the basics on food plot establishment and soil fertility management.

If your goal is to increase the amount of protein available to the deer herd then legumes are your best bet. Some warm season legumes that do well in the panhandle include Aeschynomene, Alyceclover, Cowpeas, Soybeans, Lablab, and Perennial Peanut. It is important that you select species and varieties that are suited to the conditions (especially soil properties) of the area you intend to use them. It is also recommended that you plant a variety of species in any food plot.

The species listed vary in terms of grazing tolerance and recommended planting technique. Contact your county's extension office for more details.

The species listed vary in terms of grazing tolerance and recommended planting technique. Contact your county’s extension office for more details.

Legumes provide high amounts of protein to deer and other wildlife because they contain relatively high amounts of nitrogen. Due to a symbiotic relationship with a specific type bacteria, legumes are able to utilize atmospheric nitrogen. Other plants are dependent solely on soil nitrogen. To ensure that the proper bacteria is available to the legume it is important to inoculate legume seeds prior to planting. Inoculants are available through most seed dealers. Be sure that you get the proper inoculant for the species you are planting. Aeschynomene, Alyceclover, and Cowpeas all require the inoculant for the cowpea group. Soybeans and Lablab each have a species specific inoculant. Perennial Peanut does not require inoculation because it is not planted from seeds. Additional information about inoculants, planting techniques, and fertilization is available from your county’s extension office.

Planting food plots does not guarantee any additional antler growth but it is one way to help alleviate a possible limiting factor. Habitat improvement and additional available nutrition can benefit the entire ecosystem. If you want to get the most out of your property, in terms of deer production, it is important to provide the deer what they need all year long, not just during hunting season.

Eurasian Water Milfoil: Eurasian water milfoil is a submerged aquatic plant that can be found in northwest Florida in lakes, rivers, and coastal marshes. Water milfoil forms a dense mat of vegetation that can block sunlight and habitat for native plants. These mats can increase water temperatures and interfere with boat traffic, fish habitat, and native aquatic plant species.

Eurasian milfoil was first documented in Florida in 1964. It was reportedly planted by aquarium plant dealers. It is still used today in the aquarium industry and obtained through suppliers and through internet sales. This plant is listed as a category II on the Florida Exotic Species Pest Plant Council List, which means it has the potential to overtake native submerged plant communities.

The spread of Eurasian milfoil can be caused by the breaking of stems and roots, which can be carried by boats, engines and trailers to other lakes and coastal marshes. To help prevent spread of Eurasian water milfoil to Florida’s waters, always clean off your boat, motor and trailer at the ramp to avoid transporting vegetative stems to other areas. In addition, never release or dispose of aquarium plants or animals into local waterways.

Giant Tiger Prawn: This large shrimp, also known as the Asian Tiger Shrimp and the Black Tiger Shrimp, can reach lengths between 8-12 inches.  It resembles are native edible penaid shrimp but differs in that it has distinct black and yellow stripes.  It was brought to the U.S. from the Indo-Pacific region as an aquaculture product.  There was an accidental release of 2,000 animals from a South Carolina farm in 1988.  Reports of this shrimp in the wild have increased over time.  They have been found in all Gulf coast states and there has been at least 1 record in each of the Florida panhandle counties.  The impact of this shrimp to our area is still unknown but they have a high tolerance for salinity change and consume many types of benthic invertebrates.  It is thought that they could become serious competition for our native penaid shrimp and could possible transmit diseases.  If you think you have found one of these shrimp, record size location (GPS preferred) and email information to ExoticReports@MyFWC.com.  To learn more about this species view the USGS factsheet.

The Cuban Tree Frog: was introduced into Florida as a stowaway on vehicles and plants in the 1920’s.  As of 2013, breeding populations have been recorded as far north as Georgia.  Cuban Tree frogs have larger toepads and eyes than any of the native species.  Being larger in size, the Cuban Tree frog out-competes other tree frogs for resources, to the point that they are predators of Florida’s tree frogs and inhibitors of native tadpoles.  Juvenile Cuban Tree frogs can be distinguished from natives by their red eyes and hind legs with blue bones.  Three-foot-long sections of 1.5 inch diameter PVC pipe can be placed in the landscape to monitor for tree frog species.  Should Cubans be found, they should be reported and euthanized.  For additional details visit: http://edis.ifas.ufl.edu/uw259.

Invasive Species of the Day (March 6th): Climbing Ferns & Chinese Privet

Invasive Species of the Day (March 6th): Climbing Ferns & Chinese Privet

March 6th: Climbing Ferns (Lygodium sp.) & Chinese Privet (Ligustrum sinense)

Japanese Climbing Fern (Lygodium japonicum) and Old World Climbing Ferns (Lygodium microphyllum): are presently the only non-native invasive ferns in Florida.  Both ferns reproduce and spread readily by wind-blown spores. A single fertile leaflet can produce 28,600 spores.  Animals, equipment, and even people that move through an area with climbing ferns are very likely to pick up spores and move them to other locations on the property or even to other properties.  In 2005, they covered 122,787 acres of Florida.

Japanese climbing fern is a delicate looking perennial climbing vine.  It is capable of forming a dense mat-like thatch capable of covering trees and shrubs. Initially, it was introduced from Japan as an ornamental. It is scattered throughout the lower portions of Alabama, Georgia, Louisiana, South Carolina, and south into central Florida. Further planting or cultivation of this vine is prohibited by the Florida Department of Agriculture and Consumer Services.  It climbs very quickly to the crowns of pine trees, which can move fire into the growth points during controlled burns, making it a concern on forested lands.

Old World climbing fern has been a problem for many years in central and south Florida but it is currently moving north. The first plant was documented in 1958 by a nursery in Delray Beach.  By 1965, it

was found in natural areas of Marion County.  The northern edge of its advance by 2012 was Hernando County on the Gulf side and Duval County on the Atlantic coast.

Adequate control of both climbing ferns has been achieved with multiple applications of glyphosate and/or metsulfuron. Other herbicides, such as triclopyr and imazapic have also been used to control

Japanese climbing fern.  However, when the plant is growing in areas adjacent to wetlands or water, fewer herbicides are registered for those sites.  Hand digging is also an option, except when the fern is producing spore covered leaflets.  Disturbing it then would propagate more plants.

As with most invasive plants, repeated and correctly timed treatments are likely to be necessary. For more information about climbing ferns contact your local UF/IFAS Extension Office and read the following publications: http://edis.ifas.ufl.edu/fr133  and http://edis.ifas.ufl.edu/ss-agr-21.

Chinese Privet (Ligustrum sinense): Chinese Privet is a non-native shrubby tree commonly found in forested areas in northern Florida. This eastern invader thrives in low-lying, wet areas near forest openings and fence rows. Other species of the Ligustrum genus are commonly grown in landscapes. Chinese Privet can be identified in the spring by its small white flowers which omit a foul odor. Birds easily spread this weed by feeding on and excreting the fruit which contain many seeds. Additionally, Chinese Privet can spread by underground plant structures called rhizomes which allow new shoots to sprout up from the ground from a mother plant.

For control options of Chinese Privet, see https://edis.ifas.ufl.edu/pdffiles/FR/FR25000.pdf or contact your local Extension agent.

Invasive Species of the Day (March 3rd): Wild Hogs & Lion Fish

March 3rd: Wild Hogs (Sus scrofa) & Lionfish (Pterois volitans):

Wild Hogs: Wild Hogs, also called Feral Hogs, are not native to the U.S.  Domesticated pigs were introduced by early settlers because they could adapt to a wide variety of habitats.  These pigs were kept on open ranges and used as a food source for settlers and Native Americans.  In the early 1900’s, true Eurasian wild boars were introduced for hunting purposes.  The population of wild hogs today are hybrids of Eurasian and domestic pigs.

Wild hogs are highly adaptable and can find suitable habitat easily.  Wild hogs can be all shapes, sizes and colors since they are hybrids of many different breeds.   Wild hogs sometimes resemble their domestic relatives but sometimes resemble their Eurasian backgrounds.

Wild hogs are probably the most prolific large mammals in the world.  They reach sexual maturity at a young age.  Females have multiple litters of 3-8 piglets per year.  Natural mortality rates are low.  Wild hog females and young live and travel in groups called sounders.  Sounders typically have 1 to 3 adults and several young.  When females reach maturity, they either stay with the sounder or they go out and form a new sounder with other young females.  Young males leave the sounder alone at about 16 months.

Wild hogs are opportunistic omnivores that feed by rooting and grazing.  This rooting behavior is why we consider them to beHog Poster a pest.  The impact of wild hogs on the environment is soil erosion, decreased water quality, spread of other invasive plants, damage to agricultural crops, and damage to native plants and animals.  They have been documented as threats to threatened and endangered species.  They can significantly impact populations of reptiles, amphibians, small mammals, ground nesting birds and even deer.

Wild hogs pose a health risk to humans because they can carry numerous diseases and parasites.  Care should be taken when handling wild hogs.  Wear gloves, cover any open wounds, and wear clothing that can be cleaned thoroughly. Human hunting is the most significant cause of mortality in wild hogs, although hunting alone will not control hog populations in a good habitat.  The most effective way to remove wild hogs from a location is a combination of trapping and shooting.

In Florida, wild hogs may be hunted year round on private land (with permission of the landowner) and at night with no permit required.  Hogs may be trapped year round.  Wild hogs cannot be trapped and released onto public land.  Trapped wild hogs can only be transported with a permit from FDACS) to slaughter or to an approved Feral Swine Holding Facility.  For more information on Wild Hogs, go to:  http://edis.ifas.ufl.edu/uw322 and http://www.myfwc.com/hunting/by-species/wild-hog/.  For more information on Wild Hogs, go to:  http://edis.ifas.ufl.edu/uw322

Lionfish: The Red Lionfish are a predatory reef fish that are non-native invasive species and have spread throughout Florida Waters.  They are members of the family Scorpaenidae, all members are venomous and the lionfish is no exception.  This fish is relatively small typically ranging from 12-15 inches in length and have a zebra-like appearance with long, showy pectoral fins.  They have a row of long, dorsal spines that contain venom glands.  Their native range is the South Pacific and Indian Oceans and preferred habitat is on offshore reef structures.  These fish are considered to be voracious eaters feeding on native fish, reducing vital native populations, and competing for food with native fish such as grouper and snapper.

With few predators, these fish are thriving in Florida waters, even in the northern Gulf of Mexico.  They reproduce often, sometimes all year, with their eggs hatching after about two days.  They also consume a variety of local species, causing 80% decline in reef fish recruitment and loss of some economically important species.  These fish are able to expand their stomachs for large meals and can survive starvation for over 12 weeks. These fish are an invasive species in our local waters and removal is encouraged.  The most effective control of this species is removal by human.  These fish are cryptic and nocturnal so locating them can be tricky.  Spearfishing is the method of choice, since lionfish rarely bite a hook and line.  Florida Fish and Wildlife Commission (FWC) changed regulations to increase harvesting opportunities.  Such changes include no requirement for a recreational fishing license when using spearing devices (pole spear, a Hawaiian Sling, handheld net, or spearing devices marked for use on lionfish), and no recreational or commercial bag limit, though recreational fishing license is required for other fishing methods.  Check the FWC regulations before fishing or diving for these species.

Lionfish are venomous, must be handled carefully, venom glands occur on the dorsal, pelvic and anal spines.  Lionfish sightings should be reported at 877.786.7267, if stung seek medical attention as soon as possible.  Rarely are stings fatal unless the person has an allergy to the venom.  The Poison Help Hotline can be reached at 800.222.1222.  Sighting information is being collected to track the movement of these species.  Fill out the online report on the USGS website or the REEF website.  Stay up to date on research as it pertains to this species at www.flseagrant.org.  For locals you can report sighting also at www.lionfishmap.org.

Sea Turtles are one of the largest and most beloved animals associated with Florida coastal habitats. However, there is a tiny creature that depends on the coastal dune system that few get a chance to see, the beach mouse. As the name implies, beach mice make their home on beaches and in nearby dunes. These mice are a subspecies of the oldfield mouse. There are eight subspecies, five on the Gulf Coast, two on the Atlantic, and one extinct species.

The Florida Panhandle has four beach mouse subspecies: (in order from East to West) St. Andrew beach mouse, Choctawhatchee beach mouse, Santa Rosa beach mouse, and the Perdido Key beach mouse. Beach mice utilize the primary and secondary dunes for food, water, cover, and raising young. They have many burrows throughout the dunes and forage on seeds, fruits of beach plants, and insects. Beach mice are most active during the night and considered to be nocturnal. Under the cover of darkness, they make several trips in and out of their burrows to find and cache food.  Feeding activities of beach mice disperse seeds and plants, adding to the health of the dune ecosystem.

Worldwide, the biggest threat to ecosystem biodiversity is habitat loss and fragmentation. Since beach mice are dependent on one specific type of habitat, it makes them susceptible to natural and human created disturbances. Due to loss of their primary and secondary dune habitats, all the beach mice except for one are classified threatened or endangered. The Santa Rosa beach mouse is the only subspecies that is not listed as threatened or endangered due to most of their habitat being protected within conservation lands on Santa Rosa Island.

Beach mice populations are continually monitored to track movement, growth, and reproduction. The common method for population counts is through the use of traps and track tubes that record mice tracks. Track indices have been developed to estimate mouse abundance.

A collaboration of three state agencies just concluded a five day population study of the Choctawhatchee beach mouse in south Walton County. The purpose of this effort was to study the movement in heavily (beach mice) populated areas and the effects of non-native predators on those populations. Predators specifically studied were feral cats, foxes, and coyotes. The study also evaluated the 2011 re-introduction of 50 beach mice, from the Topsail Hill Preserve State Park population into the Grayton Beach State Park population. Reintroduction was done to boost numbers of the mice in that area and expand the gene pool for the subspecies.

The data from the current effort is still being analyzed but positive results are expected due to healthy beach mice being found in areas of focus and some new areas. Public lands such as parks and wildlife refuges are important for the preservation of beach mice as well as other coastal dune species that utilize similar habitats.  It is important that awareness be shared on these and other species to help these efforts to keep our habitats safe and healthy.

Florida Snow!  Nature’s Reminder to Enhance Backyard Wildlife Habitat

Florida Snow! Nature’s Reminder to Enhance Backyard Wildlife Habitat

Even though adapted to weather extremes, these migratory American goldfinches (Spinus tristis) appreciated the food and cover provided in this backyard.  Photo by Judy Ludlow

North Florida experienced a weather delight (or distress depending on your point of view!) this week in the form of freezing rain and snow!  The words “Florida” and “snow” are two words most people would not place together in the same sentence, but you may be surprised to learn that snow has been documented a number of times in Florida as revealed by records as early as 1891.  In Tallahassee, measurable snow has not fallen since 1989.  

The following information is taken from the National Weather Service Weather Forecast Office Tallahassee, FL  about the history of Snowfall in Tallahassee:  Several winters ago, NWS Tallahassee Climate Focal Point, Tim Barry, responded to an inquiry from a reporter concerning snow climatology in Tallahassee. Some of those questions and answers are listed below.

In ten-year intervals, how many times has it snowed in Tallahassee Florida?

snow graphHow frequently does Tallahassee see snowfall?

From the information provided in the 1st question, we see that it snowed 32 times in Tallahassee since 1891. Please note that all but 7 of these occurrences were only Trace amounts. If we were to divide the period of record (117 years) by 32 we would get a frequency of once every 3.66 years. But as you can see from above, the more frequent occurrences of snow in the 50’s ,60’s and 70’s have skewed the results. The return period for measurable snow is just once every 17 years.  The most snow recorded in a 24-hour period was 2.8″ from February 12th – 13th, 1958.

Any interesting or exciting facts about Tallahassee winters?

There is a significant difference between the climate of north Florida and the southern portions of the peninsula. On average, we experience 35 days with minimum temperatures at or below freezing with most of these occurring from December through March. The coldest temperature ever recorded in Tallahassee was -2 F on February 13th 1899. More recently, we dipped down to 6 degrees F on January 21st, 1985.

Florida’s wildlife, although adapted to Florida’s weather, will thrive given the added boost of backyard habitats planned for their benefit, especially during these winter weather extremes!  During the winter, Florida’s native, resident, wildlife species are also joined by species which are here temporarily as they migrate through our state.  The hundreds of American goldfinches (Spinus tristis) outside my window are one example.

When growing your backyard habitat, think about recreating features which are naturally provided in undisturbed habitats, but only on a smaller scale.  To flourish, wildlife need adequate nutritious foods, functional cover, and clean water.  Locating food close to cover minimizes the exposure of foraging wildlife to severe weather conditions and to predation; these two factors account for a large percentage of mortality.  Cover comes in the form of trees, shrubs, brush piles, etc. of varying heights and sizes.

Brush piles such as this one provide valuable wildlife habitat for many species.  Photo by Judy Ludlow

The following information is from the Florida Fish and Wildlife Conservation Commission’s publication: Planting a Refuge for Wildlife.

Cover: Breeding, nesting, hiding, sleeping, feeding and traveling are just a few of the necessary functions in an animal’s life which require protective cover or shelter. Often plants used for cover double as food sources.  Strategic placement of cover is very important in that it reduces exposure to weather extremes and provides escape from predators.  

Food: All animals get their energy for survival from plants or other animals. The ideal wildlife management plan uses natural vegetation to supply year-round food – from the earliest summer berries to fruits that persist through winter and spring (such as sweetgum, juniper and holly). You will attract the widest variety of wildlife to your land by using native plants to simulate small areas of nearby habitat types. The “edges” where these habitat types meet will probably be the most visited areas in your neighborhood.
