Why do trees drop helicopters?
When the seed spins, the air moving over the wide end of the wing moves faster than the air closer to the seed, which gives the seed the lift it needs to stay aloft. Then there are the veins on the leading edge of the wing, which generate just enough turbulence to help it cut through the air.
Maple tree seeds go by different names like “helicopters” or “whirlers” depending on what you called them when you were a child. Regardless of what you call them, everyone knows the signature twisting, swirling, winged seeds that fall from maple trees every year.
When the seed or fruit of long-lived trees are seen in copious amounts, similar to current reports, this is known as a mast year, or masting, for that tree. Seed production occurs every year in varying amounts. However, research on masting indicates the phenomenon appears every 2-5 years.
Maple fruits are called samaras. Two achenes, containing the actual seeds, are connected in the center of the fibrous papery tissue. Their shape is perfect for seed dispersal. As they fall from trees, they float and fly like helicopters.
More commonly referred to as “helicopters,” “whirlers,” “twisters” or “whirligigs,” samaras are the winged seeds produced by maple trees. All maples produce samaras, but red, silver and Norway maples often produce the largest quantities.
The helicopters, also called whirligigs but technically known as samaras, are the outer covering that must be removed when eating seeds from maple trees. The seed pods under the covering are edible.

Its flowers are greenish-yellow and bloom in early spring. They produce paired samaras that grow to 2 inches long. These mature and fall once a year, in late spring.
Oaks create acorns for reproduction. Squirrels often collect acorns for their high-energy supply, and the squirrels nest in these trees. and nest in oaks. Maples create seed pods, often referred to as "helicopters" because of their effect when falling to the ground in autumn.
Three times more power, 50% fewer CO2 emissions
Today's helicopters play a key role in missions that help preserve the environment, such as firefighting operations or scientific projects requiring air transportation.
According to the National Transportation Safety Board (NTSB), helicopters crash at a higher rate than airplanes. The crash rate for general aircraft is 7.28 crashes per 100,000 hours of flight time. For helicopters, that number is 9.84 per 100,000 hours.
What are the odds of living through a helicopter crash?
The fatality rate of helicopter crashes is 31%. Poor. If you're in a helicopter that has actually crashed, you can be severely injured by the impact, by parts of the helicopter that break apart and by fire.
In addition, because of their abundance and ability to spread, maple seeds can be challenging to clean up. These seeds are often called helicopter seeds because they spin, and that whirling enables them to fly. When the weather is unpredictable, or the trees are stressed, they frequently do this.
Physically removing the seeds is a clear way to manage the spread of the maple helicopters. The best way to pick up maple seeds is using rake, according to Cooperative Extension System. Once maple tree sprouts have begun to germinate, pulling them by hand is quite easy, but it can take a while and can get tiring.
Helicopter seeds can cause stomach upset, vomiting and diarrhea in dogs. These plants are toxic to animals, so it's best to keep them out of reach of your dog.
Large aerial saws are flown by helicopter to trim trees in remote locations when they overgrow power lines, pipelines or other infrastructure.
However, some do sprout, and homeowners will need to pull them up by hand. The most common way to remove helicopters is by sweeping them up or raking them with a rake and putting them in a yard waste bag.
Helicopter seeds are winged seeds. Their wings are single, stiff, flat membranes, which are attached to the actual 'seed' bit and designed to help the seed catch the wind as it falls from the tree and fly away. Theis helps it move away from its parent tree so it is not competing for food, water and sunlight.
Samara fruit, also known as helicopter seeds, are beloved by many playful gardeners and nature lovers. These papery winged seeds can make for good toys and snacks. A samara is a type of dry fruit, not a fleshy fruit like an apple or cherry.
The seeds are quite small, and time consuming to peel, but given that a single hectare of maple forest can produce a million seeds, and that a single maple can live up to 400 years, the maples provide the squirrels a staggeringly abundant feast.
Maple tree seeds are edible, contain protein, and can be used as survival food in winter months, however like many wild edibles the best flavours are enjoyed in spring.
Why are there no maple seeds this year?
The most common issue reported is over production rather than under production. However, under production does not necessarily indicate that a maple tree is sick. Low maple samara production can be due to stressors such as late frost or other weather conditions.
These stringy brown tassels are called catkins or tassels. They are the male pollen structures produced by oak trees (Quercus spp.). They hang in the trees like tassels on the end of bike handlebars, releasing their pollen into the wind to fertilize the female flowers.
These little balls, called oak galls, are a common occurrence caused when the tree reacts to non-stinging wasps laying their eggs on its leaves, branches, twigs or flowers. These insects inject a hormone into the plant tissue, causing it to grow abnormally and enclose the developing wasp larvae.
If you've encountered some round, spiny balls under a tree or maybe still on the plant, and you're wondering what it could be, it's likely one of several options: buckeye/horsechestnut (Aesculus), chestnut (Castanea), or sweet gum (Liquidambar styraciflua).

Pilot error is perhaps the number one cause of these accidents. Helicopters are sophisticated aircrafts with more controls than airplanes. Pilots must be well trained to handle any weather conditions or challenging landing locations. Studies show that pilots with less experience are more prone to accidents.
Helicopter Safety and Regulations
Statistically, helicopter charters carry a little more risk than private jets and commercial airliners and they're governed by fewer regulations.
Should I Expect Any Flight Turbulence? Bumps or turbulence in helicopters are basically non-existent. Without getting into an aerodynamic lecture (as exciting as they are), a helicopter's response to light and medium turbulence is completely different to a plane.
Bell 206B3. Known for its reliability, sturdiness and unparalleled record for safety, the Bell 206B-3 is among the most exceptional turbine helicopters ever built.
The answer, based on a TPG analysis of a decade of safety data: Like almost every other mode of transportation, flying in a helicopter is considerably more dangerous than airline travel.
What happens to your body when a helicopter crashes?
The most commonly occurring bony injuries were fractures of the ribs (73.8%), skull (51.2%), facial bones (47.6%), tibia (34.5%), thorax (32.1%), and pelvis (31.0%). Common organ/visceral injuries included injury to the brain (61.9%), lung (60.7%), liver (47.6%), heart (41.7%), aorta (38.1/), and spleen (32.1%).
When a helicopter engine fails, the most important thing is to get the collective down and to do so quickly. Rotor RPM is absolutely critical! Once the RPM has dropped below a certain level, it will be impossible to get it back, and the helicopter will indeed crash and burn.
In southeastern Pennsylvania on April 4, 1991, a Piper Aerostar propeller-driven aircraft collided in mid-air with a Bell 412 helicopter over Merion Elementary School in Lower Merion Township, a suburb northwest of Philadelphia.
Sometimes when trees drop their fruit, such as nuts, acorns or maple samaras (whirlybirds) in great numbers they can be dangerous, disgusting, or just a nuisance to clean up. It doesn't happen every year but when trees produce bumper crops of fruit, we sure take notice.
Pruning, damage, pests and disease are common reasons why trees ooze and drip sap. However, certain species of trees naturally produce more sap then others, and are more susceptible to problems that lead to an excessive amount of sap dripping.
How long do maple trees live? How long a maple tree lives depends on the type of maple. A sugar maple can live up to 400 years, whereas a silver maple usually lives about a century. Red maple trees live a bit longer, surviving up to 300 years.
If you've noticed a greater-than-usual flurry of whirlybirds from your maple trees, don't worry - the sky is NOT falling. The abundance of these seeds, also affectionately called helicopters, means it is a mast year.
district manager Scott Heim explained the phenomenon this way: Every spring, maple trees produce small flowers that turn into seeds. Normally, a cold frost kills some blossoms, but this year the usual chill didn't arrive at the right time. More blossoms than usual turned to seed.
