This State Park is the Perfect Zombie Apocalypse Survival Location
Have you ever considered what you would do to survive the coming zombie apocalypse? That's a loaded question, because it implies that there is going to be a future apocalypse requiring survival. Still, it's a fun thought experiment, and I have often wondered what would happen if there was a societal reset. Who would be the survivors and would they prosper?
Ellie Schiller State Park in Homosassa Springs is my go-to for a survival situation. Clean water, mostly gated park, with the possibility of growing an abundance of land-based food. In the coldest part of winter, manatees float lazily around. During the warmer months, the place is teeming with fish. Not that I'm saying I would eat the manatees, but in a survival situation who knows what would be on the table.
I would bring my rabbits with me and some of the water hyacinth. Water hyacinth is a survival food for sure. I would probably bring the cannas too. They grow in water pretty well.

Buy this plant from me?
As you may know, cannas love full sun and plenty of water. Its hard to overwater them! They can be placed in a pot into an existing or new pond. I was thinking $5 or plant trade would be a good price, as this is a 100% organic offering of an edible suitable for the front yard.

Surprising Azolla Harvest
I have been steaming to destroy bacteria (and tadpoles) on the plants before draining and freezing into ice cube trays for ease of feeding to the rabbits. But it just brings up the good point, that if a person was starving, here is an extremely prolific food source for a survival garden.
The only way to find the betta fish is by harvesting the azolla. It might not be a good idea to add this particular floating plant to decorative koi ponds. Now that my pond is up and running, I find myself wondering why not grow edible snails? They eat algae and won't disturb the floating planters, azolla, or fish.
Azolla, Azolla spp.
This floating water plant is actually a tiny, prehistoric fern with amazing properties. It fixes atmospheric nitrogen due to its symbiotic relationship with cyanobacteria, like an aquatic version of our more common legumes. Due to its nitrogen-fixation, it is also an extremely protein-rich plant, making it an excellent choice for home-grown fodder. In fact, there are very few land-based livestock animals that will not eat azolla, if any. Chickens, rabbits, goats, ducks, and cows are reported to gorge on this aquatic plant.
Historically it has been used as a wetland green manure crop in the warmer parts of Asia. In the spring when taro or rice is planted in the boglands, the azolla would be innoculated to the water's surface. There the little ferns would fix nitrogen and proliferate, crowding out any competing algae or weeds via shading. Since the rice and taro have most of their foliage above water-level, it does not hinder their growth. The azolla will thrive, then self-mulch, then die down when the cooler weather comes. The farmers harvest some and shelter it for next year's use. The green manure properties of azolla make it possibly the six most valuable ferns on the planet.

Azolla species can be used as a very nutritious survival food for humans, but it will need to be cooked to destroy any pathogens that might be living in the watery growing media. For animals, this compilated table shows it to have 16.5% crude protein and a bevy of other useful vitamins, like leucine and alanine. This Australian study lists many of the benefits of using azolla as a large-scale fodder source, but points out a simple drawback to commercial production - that contamination of the plantings by tiny freshwater shrimp can occur. This accidental animal protein renders the azolla illegal to sell as a feed source for ruminants in Australia, as they have strict legislation prohibiting animal proteins for ruminant consumption there. They also recommend the azolla be fed fresh or refrigerated, but within a week of harvest.

Aquaponics, are we missing the point?
Aquaponics, the art of using recirculating pumps to provide habitat for fish growth and nutrition for soil-less agriculture, is commonly becoming available to everyday people via the information exchange on the interwebs. It is potentially a viable gardening technique for apartment dwellers and others who don't have access to even a small plot of semi-arable land, but does require electricity.
After reviewing systems and advice for days on end, I have decided that aquaponics practicioners are completely missing the big picture...that Humanity needs start utilizing other plant sources more effectively, and that using electricity to run pumps to grow tomatoes IS STUPID. Besides, when have Tilapia ever produced an attractive pumpkin? The answer, of course, is never.
Cattails, on the other hand, are efficient bog plants that have been staples in Native Americans' diets for thousands of years. Managed effectively, Tilapia could probably make some huge cattails, taro, watercress, duckweed, azolla, water chestnuts...and probably dozens of other potentially delicious yet unexplored margin plants. Even without fish farming, more bog plants should be explored as efficient (space and resource) fodder and food sources.
The electricity and equipment cost of aquaponics is another factor that is best forgotten until afterward, largely because the majority of people that practice aquaponics seem to be aquarium lovers who want to take their fish raising large scale, or hydroponic plant farmers who want to take their nutrition dollars away from store-bought salts. The pumping power to mechanically aerate and filter the highly stocked tanks will never be cheaper than just buying fish meat, expecially when you factor in fish feed and time. And frequent chemical tests. And the possibility of fish disease ruining your whole crop.
Just think about it.
There are very few people working on doing this sort of thing sustainably. Perhaps the best and easiest solution would be custom-built ponds with floating plant beds on the surface, with only inexpensive bubblers for aeration and circulation. There is still the fish feed issue, but perhaps it could be lessened with Azolla, Duckweed, Black Soldier Fly Larvae, and Redworms. All of which would need support systems and engineering, but are currently being done well on the small scale. There is still the solids issue. Solids are not really a problem if you have a garden, which everyone who can probably should have anyhow.

Harvesting Turtle
"Freshwater turtles can only be taken by hand, dip net, minnow seine or baited hook. Most freshwater turtles may be taken year-round. Taking turtles with bucket traps, snares, or shooting with firearms is prohibited. Softshell turtles may not be taken from the wild from May 1 to July 31. In addition, collecting of freshwater turtle eggs is prohibited.
Some turtle farms depend on collection of wild freshwater turtles. With the new rule, certified turtle aquaculture facilities, under a tightly controlled permitting system, will be allowed to collect turtles to establish reproduction in captivity so that farms can become self-sustaining to lessen their dependence on collection of turtles from the wild.
Possession limits for the following turtle species and their eggs are as follows:
- Loggerhead musk turtles - two
- Box turtles - two
- Escambia map turtles - two
- Diamondback terrapins - two"
Information on sea turtle harvesting is not listed on the FWC official site, which leads me to believe that it is illegal in Florida waters. Interestingly, Gator-Woman claims that the largest threat to Florida's indigenous turtle population is that Chinese, a blatantly racist remark. She claims their love of turtle is skyrocketing the price of domestic turtle meat.
Once you acquire the turtle you can butcher immediately, or some would recommend storing the captive turtle securely in clean water for a day or more, providing feed for the turtle as well. This is to lessen the supposed "muddy" flavor of the meat.
The proper way to clean a carcass would involve enticing the turtle to bite a stick, then pulling its neck out as far as possible before slicing through as quickly and close to the base as possible, then hang by the tail to drain the blood. Next slice off the legs, tail, and shoulders for the meat. Remove the head from the neck and use the neck meat as well. Some open the shell to remove the fatty lining near the vertebra, or strap, as it is sometimes called. Frequently that step is omitted as opening the shell may not always be worth the mess or hassle. Care should be taken to avoid reflexive movement of jaws and legs which persist long after the turtle is decapitated.
Most recipes for preparing turtle meat call for creating a soup, stew, or possible deep-frying. Some cook with the bones, some remove the bones before cooking.
Well-Depths in Florida
Silver Springs |
Wells probably should be used in conjunction with rainwater harvesting. Since the population emigrations to Florida in the 1950s, more people and industry have been drawing from the aquifers, an already fragile resource. Saltwater intrusion and lake levels dropping, combined with sinkholes, have made that plain. Sinkholes are an open wound of the water system, allowing pathogens in to infect otherwise potable water with contaminants like nitrates. Rainwater harvesting from rooftops also requires no electricity for pumping.
There is no one resource for obtaining information about water quality for an area short of drilling and hoping the sample comes back clean. Neighbors may be able to give you information about their wells. Assume all local golf courses are not going to give you information.
In general, the aquifer is between 100 and 200 feet down in most of central Florida. The ground is frequently a layer of sand on layers of limestone and dolomite. Rainfall does affect groundwater levels, in a period of intense drought hundreds of shallower wells near Pensacola had to be redrilled or moved inland. Underneath some areas the aquifer is under pressure, which might result in artesian well once drilled. Artesian wells have special regulations regarding reporting and capping (of course).
Shallower wells, about 50 feet deep, are used most frequently for irrigation (think golf courses, nurseries, and citrus farms) and usually have lower quality water than the deeper wells.
What We Can Learn from the Natives, Part 1
The indigenous people were bastions of knowledge about the scrublands of West Florida. Not only did they know about the water availability issues we face here, the forest was not food desert to them. We have a good deal to learn about their lives and livelihood.
For Hernando and Citrus counties it is known that most natives lived near thes springs and ocean. We know their diet consisted largely of fish, and that they traded with other tribes for goods. Shell Mound in Citrus County is a huge remain of their remains. It is thought the dead were entombed in cairns because of flooding and the high water table. Not a lot else is left to be found.
Water was everything to the natives. They didn't have the technology or knowledge to dig wells for fresh water. One source states that thousands of years ago the people that lived in Florida occupied areas that are now under ocean. The Wisconsin glacier is credited with raising the water level. Buried forests have been found off the coast of the Florida Keys.
We know that native Americans practiced a form of agriculture foreign to our modern life, called food forestry. It is a subject I am fascinated with, and have been endeavoring to turn my tiny lot into a miniature version of. Breaks in th e tree canopy are utilized to grow sun-loving annuals. Small perennial seeds or nuts are also planted in amongst the annuals. The area is weeded and planted, then the people return months or years later to harvest. Maybe the plants grew or maybe they did not, but it was very little effort for potentially huge returns.
