Poor Will's Almanack for the first week of Early Fall.

The movement of the sun appears to accelerate as equinox approaches, changes in the landscape speeding toward autumn. Each change is the tip of other changes.

When asters bloom in the waysides and bur marigolds flower in the swamps, then farmers are cutting corn for silage.

When zigzag goldenrod blossoms in the woods, then the rose of Sharon shrubs will drop most of their flowers and the great decline of summer wildflowers begins in the fields.

When you see fallen leaves starting to accumulate in the backwaters and farm ponds, then the grapes on your grape arbor should be getting ripe.

At the Glen Helen Nature Preserve near Yellow Springs, there’s a problem. For decades, non-native plants such as bush honeysuckle have been taking over the understory of the forest.

Last November, the Preserve received a $70,000 grant from the Nature Conservancy to remediate these invasive species. The target for the South Glen Restoration Project is a 2 ½ mile stretch alongside the Little Miami River – an area the size of 80 football fields. Each Saturday this year, volunteers join the staff as they attempt to reclaim the forest. Community Voices Producer Wally Rehm went to visit them.

George Bieri is Land Manager at Glen Helen Nature Preserve. On this Saturday morning, Bieri is leading of team of nine - mostly volunteers.

Poor Will's Almanack for the last week of Late Summer

In the last week of late summer, the final tier of wildflowers starts to open. White and violet asters, orange beggarticks, burr marigolds, tall goldenrod, zigzag goldenrod and Japanese knotweed come into bloom, blending with the last of the purple ironweed, yellow sundrops, blue chicory, golden touch-me-nots, showy coneflowers and great blue lobelia.

Less than a week after astronaut Neil Armstrong’s passing, there's a rare 'blue moon' on Friday’s cosmic calendar.

That's the day of a private service for Armstrong, the first man to walk on the moon, who died last Saturday in Ohio at age 82.

A blue moon occurs when there's a second full moon in one calendar month. It won't happen again until July 2015. The full moon cycle is 29.5 days so a blue moon is uncommon and has come to mean something rare. The moon actually won't be colored blue.

Armstrong's family has suggested paying tribute to him during Friday’s Blue Moon.
