Nostoc algae on gravel

In this month’s column of In the Grow, B. Rosie Lerner, Purdue Extension Consumer Horticulturist, addresses algae that can pop up on stone, concrete, gravel or even lawns this summer as we are getting large amounts of hot, rainy weather.

This terrestrial algae known as Nostoc can look unappealing and also be a slippery safety hazard, but unfortunately, there isn’t much to do about it. Raking the algae will just spread it to larger areas. Keeping the area aerated and dry as much as you are able can help a little with controlling this algae, and applying copper sulfate will also shrink it a little bit, but it will just reappear when warm, rainy weather conditions occur again.

This is the time of year that many homeowners start their annual battle with nuisance wildlife. While trapping animals is not always required or desirable, it may be necessary in some cases to alleviate damage. Homeowners will typically use a box-style or cage “live” trap. Before you take action, there are a few key points you should first consider.

on in a box trap

What permits, if any, are required?
Some animals require a permit prior to trapping. Raccoons, skunks, opossums, groundhogs, gray squirrels and fox squirrels are examples of mammals that do not require a permit in Indiana. Resident landowners or tenants can legally capture these species if the animal is causing damage to the property. However, you no longer have to report capture of wildlife to a conservation officer within 72 hours. Perhaps to the surprise of probably most people, rabbits do require a Nuisance Animal Control Permit prior to trapping. The Indiana DNR has a list of permitting requirements.

What do you do with wildlife you catch?
You have two choices of what to do with wildlife you capture: let it go or euthanize it (put to death humanely by injection). In either case, you may not possess an animal for more than 24 hours. If you relocate an animal, you must have permission of the landowner or property manager (even for public lands) AND you may only release that animal within the county of capture.

A common question I receive is, “What should I do?” There is no answer for which is best because circumstances differ. Most people probably prefer to let them go somewhere else because they find euthanizing animals unacceptable. They also may think that letting them go allows them to live out their lives, but this may not be the case. There has been some research on what happens to translocated raccoons and tree squirrels. In both cases, the animals don’t stay where they were let go. In the case of squirrels, a high number died within 88 days of release. Raccoons removed from structures tended to relocate in another structure.

Other things to consider

  • Despite being cute and furry, wild animals are exactly that – wild animals. You should always use caution when handling traps that contain wildlife. Wear thick leather gloves and avoid sticking fingers inside the trap.
  • If you transport an animal to be released (assuming you have gotten permission), do not place the trap inside your vehicle. Use a pickup truck to avoid contaminating your vehicle with animal waste and to minimize the spread of disease. Wildlife carry many pathogens and diseases that are transmittable to people.
  • Animals can roll traps or pull in vegetation from the immediate vicinity. Be careful where you place the trap. Staking box traps is also a good idea.
  • Be sure the trap is stable or “bedded” when you set it. Remove rocks and debris from under the trap. You may have to “work” the trap into the ground. Just be sure that debris doesn’t get caught under the treadle. If it does, the trap may not fire.
  • You may want to cover your trap by wrapping it with cardboard and wire.
  • Check your traps frequently. Indiana has a 24-hour trap check law. It is often a good idea to check them more frequently – perhaps 2 to 3 times a day. This is especially true if you are trapping during extremely hot or cold weather.
  • Wildlife species have different times of activity, so you can be selective what time of day you trap. For example, tree squirrels and groundhogs are not active at night. Closing traps at night can avoid non-targets but would also require opening the trap at sunrise.

Remove perches from wildlife nest boxes like the bluebird box pictured here. Perches allow undesirable birds to harass native cavity nesters and take over a nest box.

Even though we have had some rough weather lately, this winter didn’t seem so bad to me. Now that the weather forecast is looking positive and the days are getting longer (this month, we gain about 75 minutes – I am embarrassed to admit that I check this frequently during the winter because it helps me get through the winter doldrums), it is a good time to think about wildlife habitat projects.

Sometimes landowners and homeowners can be overwhelmed by all the different ways they can help wildlife on their property. An easy project that is also fun to build and place on your property is a nest box. You don’t want to wait much longer. Erect your nest box well before the average start of the nesting season (most birds start in mid-April, but some start sooner). Some species will set up their nesting territory three to four weeks prior to egg laying.

Many species of native birds and mammals will utilize nest boxes. When we put out a nest box, all we are doing is replicating what nature already provides with cavities in both live and dead trees. Woodpeckers are primary cavity users because they create their own. Other birds and mammals are secondary cavity users because they use what is already there – either those that occur in older, dying trees or those that are created by woodpeckers. Installing nest boxes in areas where cavities are likely scarce such as urban environments or young woods may be particularly beneficial.

Tips

  • ​Use quality materials that are weather resistant. Exterior grade plywood and lumber are good choices. Cedar and other rot-resistant woods are best. Avoid using treated lumber and metal.
  • Avoid painting or staining inside nest boxes. Painting the outside can prolong its life and may be attractive for some species (white for purple martins, for example).
  • The roof should be sloped to allow water runoff and should hang over the sides.
  • Drill at least four 3/8-inch drainage holes on the floor.
  • The roof or one side should open to allow easy access for cleaning.
  • Avoid perches. Natural cavities don’t have them and neither should your nest box. Perches also allow European starlings and English house sparrows, non-native invasive species, to harass native cavity nesters and take over a nest box.
  • Near the top of each side, leave gaps or drill 5/8-inch holes (at least two per side).

More tips on design, such as nest box specifics by species (dimensions, hole size and placement, box placement and location), maintenance and problem species, can be found in our Nest Boxes for Wildlife publication​.

You may be considering giving a plant as a holiday gift this year. But before you buy your plant, there are precautions you need to take into consideration in order to keep it healthy. Purdue Yard and Garden News has some tips for you.

Your plant can get damaged due to cold, frigid air. Ensure that the salesperson wraps your purchase to protect it from the cold temperatures and wind as you walk back to your car. Also preheat your car to keep it out of the cold for the shortest time possible.

Keep plants away from drafts when you return home. Instead, put it in a place that is 60-70 degrees Fahrenheit during the day and provides plenty of bright light. Water your plant until some excess water comes through the drainage holes at the bottom.

View all of the tips on the Purdue Yard and Garden News page.

​The Purdue Yard and Garden Calendar​ for January has provided some tips on how to care for your plants as a bitter cold winter sweeps upon us.

HOME
Keep plants near a bright window and hydrated. Increase humidity around houseplants by grouping plants together, placing them on a pebble-water tray or running a humidifier. Check stored produce and tender flower bulbs and roots for rot, shriveling or excess moisture. Remove and discard damaged material.

Repot houseplants as they outgrow current pots.​

YARD
Check young trees for rodent injury on lower trunks. Prevent injury with hardware cloth or protective collars.

Keep road and sidewalk salt away from plants. Construct a screen of burlap, if necessary, to keep salt spray off plants.​

GARDEN
Order seeds and plants as early as possible for best selection.

Wood ashes from the fireplace can be spread in the garden, but don’t overdo it. Wood ashes increase soil pH, and excess application can make some nutrients unavailable for plant uptake. Have soil tested to be certain of the pH before adding wood ash.

​As winter comes swiftly upon us, there are precautions we need to take to ensure our plants, both indoor and outdoor, are well taken care of. Below are a few examples of how you can prevent certain problems that occur in the cold months ahead. View all of the steps you can take at the Purdue Extension Yard and Garden Calendar page.

HOME (Indoor plants and activities)

  • Houseplants may not receive adequate light because days are short and gloomy. Move plants closer to windows, but avoid placing foliage against cold glass panes. Artificial lighting may be helpful.
  • Because growth slows or stops in winter months, most plants will require less water and little, if any, fertilizer.
  • Extend the lives of holiday plants such as poinsettias and Christmas cactus by placing them in a cool, brightly lit area that is free from warm or cold drafts.

YARD (Lawns, woody ornamentals and fruits)

  • Prevent bark splitting of young and thin-barked trees, such as fruit and maple trees. Wrap trunks with tree wrap or paint them with white latex (not oil-based) paint, particularly on the south- and southwest-facing sides.
  • Provide winter protection for roses by mounding soil approximately 12 inches high to insulate the graft union after plants are dormant and temperatures are cold. Additional organic mulch such as straw compost or chopped leaves can be placed on top.

GARDEN (Flowers, vegetables and small fruits)

  • To protect newly planted or tender perennials and bulbs, mulch with straw, chopped leaves or other organic material after plants become dormant.
  • Store leftover garden chemicals where they will stay dry, unfrozen and out of the reach of children, pets and unsuspecting adults.
  • Once the plants are completely dormant and temperatures are consistently below freezing, apply winter mulch to protect strawberries and other tender perennials. In most cases, two to four inches of organic material such as straw, pine needles, hay or bark chips will provide adequate protection.

It doesn’t sound like there would be much chance of the chemical to get into the shrubs if the imidacloprid is applied close to the base of the tree. Also another thing to consider is unless you’re eating solely certified organic food, there’s a really good chance you’ve consumed very small amounts of imidacloprid at some time.

The United States Department of Agriculture (USDA) Pesticide Data Program monitored imidacloprid residues in food and published their findings in 2006. Imidacloprid was detected in a range of fresh and processed fruits and vegetables. It was detected in over 80% of all bananas tested, 76% of cauliflower and 72% of spinach samples. In all cases, however, the levels detected were below the U.S. EPA’s tolerance levels. Imidacloprid was also found in 17.5% of applesauce and 0.9% raisin samples, although percentage of detections were greater in the fresh unprocessed fruit (26.6% of apples sampled and 18.1% of grapes sampled).

These findings were on direct application to the plant, which would indicate higher concentrations than that which you would find on plants nearby those that were treated. Additionally, it is advised that if homeowners want to use a product with imidacloprid as the active ingredient, then they use one specifically labeled for edible food crops. The product label will contain specific instructions on application, pre-harvest intervals and special instructions on limiting harm to pollinators.

​As foresters, woodland owners and tree and wildlife enthusiasts, we hear the word safety and immediately think about making sure our hard hat is packed, our gas tank is full, our cell phone is charged and we have a buddy to call in case of an emergency. How many of us think about diseases? Who thinks about West Nile Virus (WNV) or Eastern Equine Encephalitis (EEE)? For those of us that take our pets into the field, WNV and EEE are very real threats. West Nile Virus originated in Africa but spread quickly throughout the United States after an outbreak in New York in 1999. By 2003, 46 states had been infected, and nearly 10,000 people had fallen ill.

Although not contagious by contact with an infected person or animal, a protective layer is recommended when handling potential infected subjects. Most infected humans show no symptoms while a minority exhibit fevers, headaches, skin rashes, meningitis or encephalitis. Very few people die from WNV (< 1:1,000), but precautions should always be taken to prevent exposure. A total of 156 cases of WNV have been reported in Indiana this year with one sample being human. Other cases have been found in bordering states with 741 cases (mosquito) in Illinois, two mosquito and four human cases in Michigan, 64 mosquito cases in Ohio and zero cases of any kind in Kentucky as of August 20, 2013.

Eastern Equine Encephalitis is a rare viral disease that can be transmitted from host mosquitoes to a number of other animal species. Historical accounts of the disease show that in Midwestern states, EEE is most often found in southwestern Michigan; however, infected horses in Indiana have been found. EEE infects nearly all game birds, amphibians and reptiles, and last year in Michigan, an 8-week-old puppy.

Humans are not immune to EEE. Nearly 30% of people that develop the disease die, and approximately 50% of survivors have permanent neurological complications. Symptoms of infection may or may not occur and will often take between three and 10 days to be realized. EEE symptoms in humans range from fever, headache and nausea to abdominal pain, paralysis, seizures and fainting. An elderly woman in New England died on August 21, 2013, and was the first human casualty of the disease this year. A vaccine has been developed to prevent EEE in horses; however, no vaccine or treatment is available to protect humans or other animals from EEE or WNV. Elimination of standing water is our only defense against potential EEE and WNV threats.

As the summer is in full swing and more and more of us head out to the field, please do not forget to protect yourself and your pets from potential exposure to mosquitoes.
