Phenology: Fourth Week of June

Gardeners harvest peas, broccoli, cauliflower, beets, carrots, the first ripe raspberries, and garden blueberries such as Northblue and Northsky. Pick wild blueberries in northern Minnesota and Wisconsin. Young common loons swim with their parents on many northern lakes. June is the prime month for Minnesota's 200 nesting bird species. Agassiz National Wildlife Refuge in the northwest may be the richest bird-breeding site in the Upper Midwest, with about 140 nesting species. Showy pink and white lady's-slippers are blooming in north central state parks, like Bemidji and Itasca.

June 29, 2015: In western Wisconsin and southern Minnesota, field corn was five to seven feet high.

Species of the Month

Porcupine (Erethizon dorsatum)

Porcupine (<em>Erethizon dorsatum</em>)
Brad Bolduan

The porcupine, Minnesota's second largest rodent behind the beaver, lives in forests of the upper two-thirds of the state. With an estimated 30,000 barbed quills, porcupines are not incapacitated by a single encounter when an enemy dislodges several hundred quills. They are good swimmers for their hollow quills offer considerable buoyancy. Contrary to popular belief, porcupines cannot throw their quills.

Porcupines are active all winter long, spending most of their time in trees eating bark and resting. In summer they eat various herbaceous plants and the twigs and leaves of shrubs, and have been known to gnaw on ax handles, canoe paddles, and other wooded objects for the salt left by human sweat.

Astronomy: June

June 7-9, 2017 at 10 pm CDT
June 7-9, 2017 at 10 pm CDT
Saturn is the planet to watch this month! Find it beside the Full Moon on June 9 and opposite the Sun on June 15. Saturn is visible all night long and shines brighter than at any other time during 2017. As if that were not enough, the planet's rings are at the best angle for viewing until 2032. Although Saturn can be easily seen with unaided eyes, use a small telescope to view the rings. Check it out!

Morning Stars

Mercury is a morning star until June 21. Throughout the month, however, this elusive planet remains too close to the Sun to be seen. Consequently, Venus is the only planet visible in the pre-dawn sky. Look for dazzling Venus roughly 12 degrees above the eastern horizon. Be sure to catch the conjunction of Venus with the slender Crescent Moon before sunrise on the first day of summer.

Evening Stars

Mars has sunk so far into the Sun's glare that it is nearly impossible to locate. In contrast, Jupiter is positioned well above the southsouthwestern horizon an hour after sunset, making it the dominant object in the evening sky. Saturn, while much dimmer than Jupiter, it still a worthy sight. It appears in the southeastern sky approximately nine degrees above the horizon at 10 pm. Watch the Moon pass Jupiter on June 3 and Saturn on June 9.
