With the ongoing cold weather across the Panhandle, fish kills are being reported in many areas.
In the Panhandle, average water temperatures have dropped down to the 50s (degrees Fahrenheit) in many waterbodies. This is about ten degrees cooler than in normal years. Fish have a tolerance to temperature but when air and water temperatures decrease rapidly, fish kills may occur.

Fish kills due to cold weather are naturally occurring phenomena. In some cases there may be an ecological benefit. Exotic fish species that have adapted to Florida’s subtropical climate may not be able to withstand these colder temperatures and large numbers of the populations may be eliminated. The decrease in the population of exotic species may allow for an increase in native populations.
The Florida Fish and Wildlife Conservation Commission’s (FWC) Fish Kill Hotline provides maps of fish kills throughout the state on a monthly basis. If you see a fish kill you can report it by phone: 1-800-636-0511 or online.
The FWC Fish Kill Website also allows the user to report fish kills and search the current database for fish kills by dates, county and possible causes of fish kills. (See example search below)

Above is an example of the December 2013 reported fish kill map:
There are a number of reasons for fish kills besides cold temperatures; low dissolved oxygen levels, spawning fatalities, diseases and parasites, algae blooms and human induced fish kills.
To report a fish kill to the FWC Fish Kill hotline, you will need information such as the name of the water body, whether the water is fresh, brackish or saltwater, observations of the characteristics of the water, species and number of fish that are observed (if you don’t know the species, you can check unknown), condition of the fish and if there are any abnormalities such as lesions, etc. on the fish.
If there are too many fish to count, estimate the total number by counting how many fish are in a 10’ x 10’ area, then estimate the total area that fish are present (along the shoreline and out into the water). Estimate how many 10’ x 10’ areas would fit into the total area, and multiply that number by the number of fish in the original 10’ x 10’ area. This will give you an estimate of the total number of fish.
Make a note of the weather conditions the past few days, air temperature, rainfall, cloud cover, wind strength and directions. Talk to your neighbors to determine if they have noticed anything unusual about the waterbody in the last few days.

There are now 32 “ZNE Verified” buildings nationwide and one “ZNE Verified” district. Two of the ZNE Verified buildings are in Florida, and the one ZNE Verified district is, too; it’s the Anna Maria Historic Green Village. The other ZNE building in Florida is the TD Bank Branch – Ft Lauderdale. Both of these became ZNE Verified during the 2012 operating year, and announced in NBI’s 2013 Research Report.
Average Energy Use Index (EUI) for all 33 ZNE Verified building projects is 21. EUI is NBI’s measure of all energy BTUs (electric and gas) used to power the building. The Leon County Extension building is more energy-efficient than the nationwide average among ZNE Verified buildings, with an EUI of 19. For our square footage, the EUI that most closely matches ours is the Aldo Leopold Center’s. It has an EUI of 16, which is more than offset by its renewable energy generation of EUI 18.
The Leon County Extension building was built in 1961, renovated in 2000, and retrofitted in 2012 – with T8 lighting, solar PV and closed-loop geothermal HVAC (ground-source heat pumps). The energy system upgrades were funded by a federal energy grant and local tax dollars from the Leon County Board of County Commissioners. These upgrades complemented an underground cistern system designed and installed by staff of County Facilities Management and Public Works in 2010-2011. The four-tank, 40,000-gallon, on-site rainwater harvesting and storage system is used for irrigation of demonstration ornamental and vegetable gardens.
Combined, the water and energy conservation system retrofits have transformed the Extension Center into Leon County government’s “Sustainable Building Demonstration,” which was a vision and goal of the Board of County Commissioners and their County Sustainability Coordinator. Their vision enabled a partnership with the building occupants (University of Florida Extension faculty) and citizen advisory committee members to develop the retrofit plans, and to work with Facilities Management to operate the building efficiently.
Our 52-year-old Tallahassee building – plus 7 of the other 32 ZNE Verified projects – were renovations, not new construction. The average (EUI) of the entire renovation group nationwide was not significantly different from that of new buildings constructed with ZNE goals driving the design and engineering process from the ground up, even though new construction gives more opportunity to incorporate the latest technology in the building envelope. NBI hopes that this very important finding provides motivation for a new focus on the opportunity to successfully renovate existing buildings to meet ZNE status, starting with government agencies, academic institutions and corporations.

Fertilizer becomes a problem in the environment when either too much is applied or it is used at the incorrect rate or wrong time. Rain or irrigation water can move these nutrients (remember, fertilizer is mostly composed of nitrogen, potassium, and phosphorus) off target, leaching them into the soil and groundwater or running off into surface waters.
Once in a creek, lake, river, or bay, this fertilizer intended to improve growth of turf or landscape plants instead fuels the growth of algae. In certain conditions this causes eutrophication, an overabundance of algae growth which gives water bodies a green, scum-covered appearance. As this plant material eventually breaks down, it uses up oxygen in the waters below, reducing the amount available for fish and other aquatic species. These scenarios can lead to fish kills and reduced water quality.

The new legislation encourages professional lawn care staff to take a day-long course covering these concepts, and additional topics such as irrigation, pest management, and proper landscaping practices. The course, offered online and in every UF IFAS Extension office, prepares the audience for the test and certification, and gives useful tips and information for their everyday work.
Several counties, most recently Escambia, have passed local ordinances echoing the requirement to have this license when seeking a business tax certification to operate a lawn care service (providing fertilizer) in the county. In addition, local ordinances typically have a “prohibited application period,” which may involve a particular time of the year or weather condition. The ordinances also restrict blowing or sweeping lawn debris into storm drains, which can cause the same water quality problems as excess fertilizer. Visit the GI-BMP website to learn more about the program, and if you, friends, or neighbors use a professional lawn care service to fertilize your lawn, be sure to ask for proof of their fertilizer license.

Deer feeders are common in North Florida, and “deer corn” is sold in multiple markets. Cross-roads convenience stores sell it in plain brown bags and big box stores in town sell it in camouflage bags with three color pictures of giant bucks on the front. With the high price of corn in 2012, many hunters saved a few dollars buying “combine run” corn from local farmers or corn screenings from grain elevators. The corn’s no different, however, either product can contain weed seed, especially Palmer amaranth. These weeds can mean big trouble for farmers and hunters.
Palmer amaranth is a species of pig weed, but it’s not your granddaddy’s “careless weed”. It’s taller than either red root pigweed or spiny pigweed, and is becoming resistant to several herbicides, most notably glyphosate (“Roundup”). Amaranth seed are small and plentiful (1 to 1.5 millimeters in diameter) and easily can fit in the nooks and crannies of grain harvesting and handling equipment.

Once Palmer amaranth seed make it into a deer feeder, there’s a huge opportunity for seedlings to take root in places under the radar of typical scouting and control measures. If these seedlings are herbicide resistant, you’ve done far more harm to the landowner than any savings on corn cost can offset. Conservative estimates indicate herbicide costs have at least doubled due to herbicide resistant weeds. Do your local farmer a real favor; scout and control weeds coming from your deer feeder.
Feeding corn to deer and turkey is permitted by the Florida Fish and Wildlife Conservation Commission as long as the following restrictions are met. “Resident game and wild hogs may be hunted in proximity of year-round game-feeding stations on private lands, provided the feeding station has been maintained with feed for at least six months prior to taking resident game,” and “Wild turkey may not be taken if the hunter is less than 100 yards from a game feeding station when feed is present.” See General Information regarding Feeding Game at http://myfwc.com/hunting/regulations/general-information
