Good Teachers

Florida Master Naturalist Student and Florida State Park Ranger, Bruce Williams, prepares for his snowy plover lesson.

There is an oft quoted proverb “those who can’t do, teach.”  It is meant to be humorous, but it couldn’t be farther from the truth.  Teachers of all kinds have enormous impacts on our lives.  For graduates of the Florida Master Naturalist Program (FMNP) there is a line in the mission statement that reads “The FMNP teaches those who teach others about Florida’s unique ecosystems and wildlife.”  In fact, to graduate, FMNP students must complete a project and present, or teach, it to the class.

A good teacher, like a good entertainer first must hold his audience’s attention, then he can teach his lesson (John Henrik Clarke).  In a recent coastal class, we had the good fortune of having a State Park Ranger as a student.  His job requires him to do interpretive education at the park, so he had quite a bit of experience under his belt.  His project, a craft project involving the assembly of a cute snowy plover chick, was his way of holding his audience’s attention while he talked of the importance of preserving and protecting habitat for shorebirds.

I thought the project and message was impressive and worthy of sharing. To all of you teachers out there who work to make our lives and world better, thank you, and here is another great activity to add to your quiver.

Making cotton ball snowy plover chicks

Group Project: Make a Snowy Plover Chick (Peipert, 2011)

This project is suitable for Elementary age through Middle school age children. It is recommended when doing project with a class or large group that some preparation is done ahead of time.

Supplies:

corrugated cardboard (disassembled brown packing box will do)

1 bag of cotton balls

1 container of black glass beads (sold at craft stores)

black sunflower seeds

1 container of wood toothpicks (kind with one end blunt)

1 can of black spray paint

several of each black, brown & gray markers

several bottles of quick dry tacky glue (sold at craft stores)

Cotton ball snowy plover chick craft

Preparation:

  • Using an exacto or carpet knife and T-square cut corrugated cardboard into 3”x3” squares for the # of stands needed. To complete stand preparation, write Snowy Plover chick on stand, draw a pair of feet in center of stand and pierce cardboard in center of feet. This step is a real time saver and recommended for young children.
  • Paint toothpicks with black spray paint for legs, easiest way to do this is by taking toothpicks and sticking them into a spare piece of cardboard upright them paint.

Instructions: (skip to instruction #3 if using stands with feet & holes premade)

  1. Draw a pair of bird feet on center of cardboard and if you want write” Snowy Plover chick” on cardboard.
  2. Use the pointed end of a toothpick to make a hole in the center of drawn feet. Then put the blunt end of toothpicks in the holes and put a heavy glob of glue around them. Don’t be shy with the glue, it will dry clear and will be better support.
  3. Take one of the cotton balls and roll around between hands to make it smaller. This will be the head. Next using all three or two markers make many dots on one side of both cotton balls creating a speckled pattern.
  4. Put a glob of glue at top of each toothpick and put larger cotton ball (the body) on top of toothpicks pushing down so the glue is covered by the cotton ball. Next put a glob of glue on the top of body and put white side of cotton ball (the head) on glue.
  5. To complete the chick put a small glob of glue on opposite sides of head then place glass beads on. Lastly put a glob of glue on side of head that the feet are facing forward and place sunflower seed on with the pointed end facing out.
  6. Let stand for at least 15 minutes to dry before handling.
  7. Enjoy your Snowy Plover chick creation!
Groundhog or Gopher?

Groundhog or Gopher?

Groundhog

Groundhog Day is celebrated every year on February 2, and in 2021, it falls on Tuesday. It’s a day when townsfolk in Punxsutawney, Pennsylvania, gather in Gobbler’s Knob to watch as an unsuspecting furry marmot is plucked from his burrow to predict the weather for the rest of the winter. If Phil does see his shadow (meaning the Sun is shining), winter will not end early, and we’ll have another 6 weeks left of it.  If Phil doesn’t see his shadow (cloudy) we’ll have an early spring.  Since Punxsutawney Phil first began prognosticating the weather back in 1887, he has predicted an early end to winter

only 18 times.  However, his accuracy rate is only 39%.  In the south, we call also defer to General Beauregard Lee in Atlanta, Georgia or Pardon Me Pete in Tampa, Florida.

But, what is a groundhog? Are gophers and groundhogs the same animal?  Despite their similar appearances and burrowing habits, groundhogs and gophers don’t have a whole lot in common—they don’t even belong to the same family. For example, gophers belong to the family Geomyidae, a group that includes pocket gophers, kangaroo rats, and pocket mice. Groundhogs, meanwhile, are members of the Sciuridae (meaning shadow-tail) family and belong to the genus Marmota. Marmots are diurnal ground squirrels. There are 15 species of marmot, and groundhogs are one of them.

Science aside, there are plenty of other visible differences between the two animals. Gophers, for example, have hairless tails, protruding yellow or brownish teeth, and fur-lined cheek pockets for storing food—all traits that make them different from groundhogs. The feet of gophers are often pink, while groundhogs have brown or black feet. And while the tiny gopher tends to weigh around two or so pounds, groundhogs can grow to around 13 pounds.

While both types of rodent eat mostly vegetation, gophers prefer roots and tubers while groundhogs like vegetation and fruits. This means that the former animals rarely emerge from their burrows, while the latter are more commonly seen out and about. In the spring, gophers make what is called eskers, or winding mounds of soil. The southeastern pocket gopher, Geomys pinetis, is also known as the sandy-mounder in Florida.

Southeastern Pocket Gopher

The southeastern pocket gopher is tan to gray-brown in color. The feet and naked tail are light colored. The southeastern pocket gopher requires deep, well-drained sandy soils. It is most abundant in longleaf pine/turkey oak sandhill habitats, but it is also found in coastal strand, sand pine scrub, and upland hammock habitats.

Gophers dig extensive tunnel systems and are rarely seen on the surface. The average tunnel length is 145 feet (44 m) and at least one tunnel was followed for 525 feet (159 m). The soil gophers remove while digging their tunnels is pushed to the surface to form the characteristic rows of sand mounds. Mound building seems to be more intense during the cooler months, especially spring and fall, and slower in the summer. In the spring, pocket gophers push up 1-3 mounds per day. Based on mound construction, gophers seem to be more active at night and around dusk and dawn, but they may be active at any time of day.

Pocket Gopher Mounds

Many amphibians and reptiles use pocket gopher mounds as homes, including Florida’s unique mole skinks. The pocket gopher tunnels themselves serve as habitat for many unique invertebrates found nowhere else.

So, groundhogs for guesses on the arrival of spring.  But, when the pocket gophers are making lots of mounds, spring is truly here.  Happy Groundhog’s Day.

Outdoor Ethics

Outdoor Ethics

The controversial incident recently in New York between a birdwatcher and a dog owner got me thinking about outdoor ethics. Most of us are familiar with the “leave no trace” principles of “taking only photographs and leaving only footprints.” This concept is vital to keeping our natural places beautiful, clean, and safe. However, there are several other matters of ethics and courtesy one should consider when spending time outdoors.

  1. On our Gulf beaches in the summer, sea turtles and shorebirds are nesting. The presence of this type of wildlife is an integral part of why people want to visit our shores—to see animals they can’t see at home, and to know there’s a place in the world where this natural beauty exists. Bird and turtle eggs are fragile, and the newly hatched young are extremely vulnerable. Signage is up all over, so please observe speed limits, avoid marked nesting areas, and don’t feed or chase birds. Flying away from a perceived predator expends unnecessary energy that birds need to care for young, find food, and avoid other threats.

  2. On a trail, the rules of thumb are these: hikers yield to equestrians, cyclists yield to all other users, and anyone on a trail should announce themselves when passing another person from behind.
  3. Obey leash laws, and keep your leash short when approaching someone else to prevent unwanted encounters between pets, wildlife, or other people. Keep in mind that some dogs frighten easily and respond aggressively regardless of how well-trained your dog is. In addition, young children or adults with physical limitations can be knocked down by an overly friendly pet.
  4. Keep plenty of space between your group and others when visiting parks and beaches. This not only abides by current health recommendations, but also allows for privacy, quiet, and avoidance of physically disturbing others with a stray ball or Frisbee.

Summer is beautiful in northwest Florida, and we welcome visitors from all over the world. Common courtesy will help make everyone’s experience enjoyable.

Sea Pork: A shoreline oddity

Sea Pork: A shoreline oddity

Recently I was walking the beach, enjoying a sunset and looking around at the shells and other oddities in the wrack line where waves deposit their floating treasures. Something bright green and oblong caught my eye. It was emerald in color, smooth yet fuzzy at the same time, and firm to the touch. At first, I thought it was a sea bean–a collective term for the many species of seeds and fruits that float to our shores from tropical locations in the Caribbean or Central/South America. The bright green definitely seemed like something botanical in nature. However, the vast majority of sea beans have a woody, protective shell similar to our more familiar pecans or acorns.

I remembered a family member asking about finding a mystery chunk of pink mass she found on the beach a few years ago. It resembled a pork chop more than anything else.

Looking closer and consulting a couple of resources, I realized we had both (most likely!) happened upon one of the oddest and often-questioned finds on our beaches: sea pork. Ranging in color from beige and pale pink to red or green, sea pork is a tunicate (or sea squirt), a member of the Phylum Chordata, home to all the vertebrate and semi-vertebrate animals. While they look and feel more like a cross between invertebrate slugs or sponges, the tunicates are more advanced organisms, possessing a primitive backbone in their larval “tadpole” form. Despite their blob-like appearance, they are more closely related to vertebrate animals than they are to corals or sponges.

During their short (just hours-long) larval stage, the tunicate larvae uses its nerve cord (supported by a notochord similar to a vertebrate spine) to communicate with a cerebral vesicle, which works like a brain. Similar to fish, this primitive brain uses an otolith to orient itself in the water, and an eyespot to detect light. These brain-like tools are utilized to locate an appropriate location to settle permanently. Using a sticky substance, the tunicate will attach its head directly to a hard surface (rocks, boats, docks, etc.) and go through a metamorphosis of sorts. The tunicate reabsorbs its tail and starts forming the shape and structure it needs for adulthood.

As an adult, the organism has a barrel shape covered by a tough tunic-like skin (hence “tunicate”). Adult bodies have two siphons, one to bring water in, another to shoot it out (giving them their other nickname, the sea squirt). The water passes through an atrium with organs that allow it to filter feed, trapping plankton and oxygen. The tunicates will spend most of their lives attached to a surface, pumping water in and out as filter feeders. They may be solitary or live in colonies, and vary widely in color and shape, lending variety to those chunks of sea pork found washing up.

I am still awaiting positive identification from an expert on my green find to confirm that it is, indeed, a tunicate and not an unfamiliar plant. Consulting with Extension colleagues, for now we are pretty confidently going with green sea pork. If you have seen one of these before or something resembling sea pork, let us know! It is fascinating to see the variety and unusual shapes and colors.

Wildlife Food Plots: Chufa for Wild Turkeys

Wildlife Food Plots: Chufa for Wild Turkeys

Wildlife management continues to be an area of growing interest on our local farms and ranches and has the potential to generate significant additional income to the farm enterprise.  It is also an opportunity to practice good stewardship of the natural resources that we have in abundance here in the Panhandle.  Each spring I get many phone calls from landowners wanting to know what they can plant to encourage wild turkeys to utilize their property more and to enhance the quality of their wild turkey habitat.  Chufa is one such plant that wild turkeys love like most of us love ice cream and it is easy to grow and will provide feed for turkeys for several months.

What is chufa?  Chufa is an African variety of the native nutsedge, which is a warm season perennial plant.  However, chufa is not as aggressive as the native nutsedges and typically will not create problems with succeeding crops that you might plant after it.  The actual foliage of the plant is not utilized by wildlife, but turkeys, hogs, ducks, and raccoons love the underground tubers that the plant produces.  Each individual plant can produce 10 to 75 peanut kernel sized tubers (see photo 1) that wildlife utilize.  These tubers are high in carbohydrates and protein, and they are also edible by humans, having a sweet taste similar to almonds or raw peanuts.

Turkeys will usually begin to dig the chufas up in early fall as soon as the above ground leaves turn brown.  In Florida, they will dig and eat the nuts from fall throughout the winter and into spring. (see photo 2 of turkeys feeding in a spring chufa patch)

If you are considering planting chufa there are several considerations to take into account.  The chufa plant typically grows well anywhere that field corn can be grown.  You should soil test the area you intend to plant and lime to a pH between 6.0 – 6.5.  On most soils this requires 1 ton of lime per acre.  Recommended planting dates are April 1st through June 30th in the panhandle area.  Earlier plantings will provide higher yields, whereas later plantings typically will provide foraging for wildlife later into the following spring.  To maximize use by turkeys into the spring I would recommend looking at planting in June.  Chufa can be planted later than June 30th some years but remember that it takes the plant approximately 90 days to produce mature tubers and this must be accomplished prior to frost/cold weather.  Plant the seed into a well prepared and fertilized seedbed.  The seeding rate for chufa is 40 – 50 pounds per acre broadcast or 30 pounds per acre drilled on a 36 inch row spacing.  Strive for a coverage of 3 or 4 seed per square foot.  When broadcasting the seed, set your disk to cut about 4 inches deep.  This will cover the seed to an approximate depth of 2 inches which is ideal for chufa.  Normal fertilizer recommendations would be 200 pounds of 17-17-17 per acre or equivalent at planting.  When the plants are 6 – 12 inches high (approximately 1 month old) you should top dress with 100 pounds of actual N per acre (300 pounds of ammonium nitrate) to maximize yields.  With high costs of fertilizer this may not be as desirable, but yields will be smaller if fertilizer rates are reduced.  For weed control options on chufa plantings consult with your local County Extension Agent for up-to-date recommendations.

Small plantings are feasible (less than ¼ acre) if wild hogs are not present.  It has been my experience that best results are obtained with ½ acre or larger plantings.  Chufa is a plant that will do a good job of reseeding itself, sometimes for several years.  Reseeding can be accomplished by simply disking the area of the previous planting between April and the end of June and following fertilizer recommendations for the initial planting.  For most locations it is advisable to move the chufa plot to a different location after the second crop to avoid problems with soil pests. (see photo 3 of typical planting).

If you have never planted chufas before for your turkeys, you may want to pull some up or disk a row up in the fall after the tops have died back.  This will assist the turkeys in finding the plants if they have never encountered it before.  Once they do find it you can expect to find tremendous areas of scratching.  Quite often the plots will literally look like a mortar or bombing range where the turkeys dig down to get the chufas!
