FORAGES

A Walk on the Wild Side: Cool-Season Forages for Wildlife Food Plots in North Florida   A.R. Blount, S. M. Olson, C.G. Chambliss, K.H. Quesenberry, and R.D. Barnett, North Florida Research and Education Center and Agronomy Department-University of Florida    (NFREC Extension Report 2001-04)

 

There is tremendous interest in wildlife forages nationally, but Florida lends itself to a different set of challenges for successful food plot plantings. Our light, sandy soils, hot and humid summers, and distinct seasonal droughts make our selections of forages for wildlife unique and challenging to suit our climate. It is important to soil test your food plot site. We recommend using adapted varieties developed for our particular growing conditions. We also suggest the use of forage blends to increase the longevity and stability of the plot, as well as forage variety for wildlife.

 

Cool Season Legumes (clover, alfalfa, vetch, etc.): Winter legumes are more dependable on the heavier clay soils of northwest Florida, or on sandy soils that are underlain by a clay layer. Inoculation of any legumes used is very important since it eliminates the need to supply nitrogen. Many clovers and alfalfas come pre-inoculated. If the legumes that you intend to use are not pre-inoculated, there are commercially available inoculants that are specific to each legume variety. (See NFREC Extension Report 2001-03 for more details on legume inoculation.)

 

Alfalfa – This high quality legume is usually grown as a winter annual in Florida. New varieties have been selected under grazing by cattle and are low-dormancy types that will sprout and grow in our mild winter climate. Alfalfa requires a soil pH of 6.5-7.0, high soil fertility and good management. Recommended varieties are Florida 99, Alfagraze and Amerigraze 702.

Arrowleaf Clover – This is an annual clover that is similar to crimson clover in soil adaptation, management and fertility requirements. It is mainly grown on heavier soils in Northwest Florida. It makes more growth in late spring than crimson. The recommended variety is Yuchi.

Red Clover – This clover behaves as a winter annual under most north Florida conditions and some reseeding may occur. Non-dormant (or low dormancy) varieties are recommended. Red clover does not tolerate flooding, and the Florida variety Cherokee appears to be very well adapted to north Florida. Recommended varieties are Cherokee, Kenland, Redland III, and Kenstar. (Cherokee, developed in Florida, is an earlier, non-dormant, and higher yielding cultivar.)

Crimson Clover – This is a well-adapted legume for north Florida. It is an annual clover that is adapted to fertile, well-drained soil. Of the clovers, it appears to be the least sensitive to soil pH. It has a short growing season, and may be grown in combination with ryegrass, clovers or a small grain crop to extend the period of forage availability. Recommended varieties are Flame, Dixie, Chief, Tibbee, and AU-Robin.

Vetch – Vetch grows best on well-drained, fertile, loamy soils. It has a spreading, viney growth habit and is an annual plant. The plant does reseed itself fairly well. Seed and foliage are consumed by many wildlife species. Recommended varieties are Cahaba White, Hairy, Common, and AU-Early Cover.

White Clover – White clover in Florida is usually a winter annual, but may act as a short-term perennial under optimum growing conditions. It is adapted to moist soils throughout Florida and is a good reseeder. Nematodes and other pests can limit production. Recommended varieties are Osceola (developed in Florida), Louisiana S-1, and Regal Ladino.

Berseem and other miscellaneous clovers – There are many other small seeded clovers, including Rose, Berseem, Hop, Bur, Subterranean and Ball clover, which will work fairly well for wildlife food plots. Little local seed availability or high seed costs may be limiting factors. Generally these clovers produce less forage than crimson, white, arrowleaf and red clover and have a short duration growing season. Ball and hop clovers do reseed well.

 

Winter Peas - This annual legume is best suited to well-drained soils with high clay content. They typically are not very cold hardy. Austrian is the recommended variety

 

Cool Season Grasses: Cool season grasses generally include ryegrass and the small grains: wheat, oats, rye, and triticale (a man-made cross of wheat and rye). These grasses provide excellent winter forage and a spring seed crop which wildlife readily utilize.

Oats - May be planted and grazed by wildlife earlier than rye, but are not as cold hardy as rye or wheat, and may be susceptible to freeze injury. It is important to choose recommended oat varieties. Recommended varieties are Florida 502, Florida 501, and Coker 820 for early season grazing. Horizon 314, Chapman, Harrison, Terral Secretariat LA495, Coker 227, Ozark, AR-County Seeds 833, 811,and LA604 for winter and spring grazing. Horizon 314 is a relatively new,  well adapted variety for north Florida.

Rye - Rye is widely used for winter grazing for cattle, but may be grazed by deer as well. Rye is more cold tolerant than oats, produces more forage than either oats or wheat, but should not be planted as early as oats. Recommended varieties are Florida 401 and Florida Black for late fall and early winter and Wrens 96, Wrens Abruzzi, Bates, Elbon, Bonel, Oklon, Maton, Pennington Wintergraze 70, and Gurley Grazer 2000 for winter and spring grazing.

Wheat and Triticale – Wheat and triticale makes excellent forage and seed production for wildlife. Recommended wheat varieties for grazing are AGS 2000, Pioneer 26R61, Florida 304, Pioneer 2684, Coker 9835, Roberts, GA-Gore, GA-Dozier. AGS 2000 and Pioneer 26R61 are two new varieties available for the first time in 2000, and they have performed very well in cool-season variety testing. Triticale is a very high quality,  robust small grain. It has good disease and insect resistance, and grows well even when late planted in December and January. Seed availability may be limited because seed production is scarce. Recommended varieties include Sunland and Florico.

Ryegrass - Ryegrass is a valuable and hardy forage crop for use on flatwoods soils or the heavier sandy loam soils in northwest Florida. Seeding ryegrass with small grains and clover lengthens the seasonal forage availability. Recommended varieties are Jumbo, Florlina, Surrey, Jackson, Magnolia, Rio, Gulf, Southern Star, Big Daddy, TAM 90, Passeral Plus, Rustmaster, Stampede, Fantastic, Graze-N-Gro, King, and Prine. (Other new varieties may be suitable but have not been adequately tested in Florida.)

Brassica and Forage Chicory Crops: At this time not a lot is known about adaptability of forage brassicas and chicory to Florida or the acceptability by wildlife as a food source.  Brassicas are annual crops, which are highly productive and digestible and can provide forage in as short as 40 days after seeding. Forage brassica crops such as turnip, swede, rape, and kale can be both fall and spring-seeded.  Kale is very winter hardy. Varieties include Premier, Vates and Siberian. Rape would also be considered to be very winter hardy.  Varieties include Rangi, Rangiora, Barnapoli, Dwarf Essex, Emerald and Winfred. Turnip or Turnip Hybrids grow very fast, reaching near maximum production levels in 80 to 90 days. Varieties include Purple Top, White Globe and Barkant. Swedes produce a large edible root. Swede yields are higher than those of turnip, but they grow slower and require 150 to 180 days to reach maximum production. Chicory is a perennial plant (forb) that is suited to well or moderately drained soils with medium to high fertility levels and a pH of 5.5 or greater. Varieties available at this time are ‘Puna’ and ‘Forage Feast’.

FORESTRY

Fern Threatens Pine Straw Industry

 

Dr. Jarek Nowak

 

Pine straw producers in North Florida are facing a new threat from the non-native invasive plant species called Japanese climbing fern (Lygodium japonicum).  The Japanese climbing fern is a perennial climbing and twining, vine-like plant, native to tropical and subtropical areas of eastern Asia and Australia.  The species was brought to the U.S. in 1930s for ornamental purposes.  The widely creeping plants often form mats (Figure 1) and become shrub- and tree-covering infestations.  Stretching from slender rhizomes, the vines can climb along tree trunks up to about 20 feet (Figure 2).  Within Florida, Japanese climbing fern is distributed throughout the panhandle and south to central Florida.  The plant has been found to invade Florida’s natural and managed forest areas alike.

 

While Japanese climbing fern threatens native biodiversity in our forests, it also has been increasingly a nuisance for private landowners and pine straw producers for the past 5 years.  Dense infestations of the species covering the ground between the rows of trees limit or deny access to fallen pine needles, making collection of pine straw difficult or impossible.  Whenever producers attempt to harvest pine straw despite infestation, the mulch is likely to become contaminated with fern fronds and/or spores, which can potentially contribute to the spread of the species.  Fronds of the species were discovered earlier this year in pine straw shipped to clients in North Florida.  Japanese climbing fern is on the list of prohibited plants (Florida Department of Agriculture and Consumer Services’ Rule 5B-57).  This means that any sale, transport or movement of any part of the plant is prohibited.

 

Florida Department of Environmental Protection (DEP) and other state agencies including University of Florida’s IFAS initiated research and demonstration trials to develop ways of coping with this new threat to Florida’s biodiversity and pine straw industry.  Early trials by the Florida DEP and Northwest Florida Water Management District indicate that glyphosate containing herbicide Rodeo at 1.5% concentration (0.8% of active ingredient) was the most effective for long-term control of Japanese climbing fern (79% mortality at 315 days after treatment).  Garlon 3A at 5% concentration showed the best short-term results (100% fern mortality at 42 days after treatment).  Garlon 4 at 5 % concentrations was the least effective of the three herbicides tried in this study.  Further DEP trials are underway in Hamilton and Calhoun Counties with Accord, Garlon 4 and Vetran 720 herbicides.  Research being initiated by IFAS will address spore viability, pine straw contamination and other issues related to potential spread of the fern, in addition to measures controlling fern infestations in pine stands.
