Trees For Kids Grant Applications Due March 1


Trees For Kids grant applications are available online for schools and communities to involve youth in planting trees this spring. The grants pay up to $5,000 for landscape trees and mulch for schools, communities and other public areas.
Trees may be planted in either spring or fall. The deadline for submitting a spring application is March 1, 2017. Each planting project is required to have an educational component for the youth.  
Studies show trees planted around schools and in neighborhoods give youth increased levels of concentration, lower levels of aggression, lower levels of obesity and fewer symptoms of ADHD.
Trees for Kids also offers no-cost seedlings packets, consisting of 200 bare-root tree and shrub seedlings, to schools and communities to plant and distribute to students, staff and community members. Order forms are available on the Trees For Kids Earth Month Celebration link. Orders must be submitted by April 1, 2017 for spring delivery.
The Trees for Kids and Trees for Teens grant program is funded by Iowa Department of Natural Resources Forestry Bureau, MidAmerican Energy, Black Hills Energy, Alliant Energy, Iowa Bankers Association, Trees Forever, Iowa Tree Farm Committee and the Iowa Woodland Owners Association.
Information on how to apply for a spring Trees For Kids grant, or receive Earth Day Celebration seedlings is available online at www.iowadnr.gov/Conservation/Forestry/Urban-Forestry or by contacting Wagner at laura.wagner@dnr.iowa.gov.

Winter Camouflage and Coloration in Iowa's Wildlife

For many Iowa animals, the stark landscape – bare trees and a bright white groundcover – makes them stand out more in the winter, which is good news for those who enjoy watching wildlife. But for a few Iowa critters, winter is a time for them to blend in with the scenery.

Jackrabbits
They may have “rabbit” in their name, but Iowa’s jackrabbits are actually hares, related more to the snowshoe hare than the cottontail rabbit. Come winter, jackrabbits shed their summer fur – brownish-gray speckled with brownish black and a white tail – to make way for their white winter coat. The only coloring left is black on the tips of the jackrabbit’s ears and a light gray tinge to the ears and back. The changing coat allows the jackrabbit to hide better in the conditions that different seasons bring.

What it can’t hide from, however, is habitat loss and wet weather during nesting seasons. Once widely found in grasslands in northwestern Iowa and once a common game species, their numbers have declined in recent years.

Snowy owls
The snowy owl can be a winter visitor in Iowa. It can be difficult to discern the precise reason why any snowy owl may be turning up further south than normal, the reason is usually not to the benefit of the owl. Common reasons for these southern “irruptions” can include shortages of food (lemmings) further north in core wintering areas, or an excess of young birds that are driven from the better northern wintering areas to sub-par locations further south. So if you spot one, it’s a rare sight indeed.

Least weasels
The smallest weasel in Iowa and the smallest carnivore in the world, the least weasel also has two color phases. It loses its reddish-brown coloring on its back, sides, tail and top of its head to get ready for winter, when it may become all white. Spring and fall coloring are often a mix as the color transition takes place. It’s not likely you’ll see a least weasel, as they primarily hunt at night and below the snow, but you’ll occasionally find them caught above a hard-crusted snow. Least weasels are small guys, rarely growing longer than 10 inches long.

American goldfinch
Iowa’s state bird doesn’t lose all of its coloring in winter, but if you see one in winter, you’ll notice its hue is more muted than its usual bright yellow. Most birds sport vibrant colors in the spring to attract a mate during breeding season. They then molt their feathers to bring in a more drab coloration for the winter, as their normal bright coloration would make them more visible to predators.

Trumpeter swans
Trumpeters’ year-round white coloring does allow them to blend in with the snow – mostly. Their large black bills and black legs provide enough contrast against the white snow to allow you to spot them pretty easily.

Activities to use while studying camouflage:
  • Color Crazy- recognize and generalize that wildlife exists in many colors
  • Quick Frozen Critters- describe adaptations related to predator and prey relationships, explain the importance of adaptations in these relationships and describe how they limit wildlife populations
  • Surprise Terrarium- identify camouflage as an adaptation and describe the importance of adaptations to animals
  • Thicket Game- identify examples of adaptation in animals and describe the importance of adaptations
