Featured Process:  It’s fall, after all  

Leaves are falling, or have fallen.  The ground in wooded areas is a kaleidoscope of colour. That corky layer we mentioned in early October has done its job – an adaptation to the increasing darkness, and “drought” that is coming when the surface- and some groundwater freezes.

Keep an eye out for what trees are still clinging to their leaves.  Among natives, there may be young American Beech, Sugar Maple, and Ironwood, and mature Red Oaks, Silver Maples, and TamaracksTamaracks (or larches), our only conifer that drops its needles in the autumn, in particular are bright yellow beacons along the edges of now-drab wetlands.

And just as those exotic or introduced species may have turned colour later, they will also drop their leaves later.  See if any Norway Maples (often dotted with tar spots ) or   Common Buckthorns are still holding some leaves by Remembrance Day, or later.  Also compare the amount of leaves still on trees in and outside of town.  Most city trees, especially ones near streetlights, tend to hold their leaves longer than wild trees. 

And if you can get to a fairly diverse woodlot, or even a playground surrounded by several different kinds of trees, have your kids each collect as many leaves as possible for 20 seconds or so, and then sort them into similar piles.   See how many different kinds of trees there are, which tree has the biggest pile of leaves, count and graph, compare and contrast, do rubbingswhatever!  See which nearby tree holds its leaves the longest, and when the very last leaf falls. 

Other Happenings: 

  • White-tailed Deer bucks are “in rut”, or at their sexual peak.  At this time they are very aggressive, and should be viewed only at a distance. Look for antler rubs on saplings and small trees – they are smooth instead of tooth-marked, and carry scent signs.  They will also scrape away the leaf litter with their antlers, and urinate on their hind legs so that the urine passes over glands which carry scent down to the cleared ground.  Look for hoof prints as well in these scrapes.  Deer are very active at this time of year, and November has more deer collisions than any other month.  Slow down in deer country, especially at dusk and at night. 
  • Brook Trout (actually a char), whose colours we began to admire in mid-September, are spawning. They prefer places where groundwater wells up, but also spawn over gravel substrate in shallow headwater streams.  Lake Whitefish  are the last spawners of the season, spawning when temperatures drop below 8ºC in shallow waters usually with hard or stony bottoms, but sometimes sandy. Lake Whitefish is one of Ontario’s most commercially important fish species.  Learn more about Ontario's fish species through this year’s Kid’s Fish Art Contest  for grades 4-12, with chances to win great prizes!
  • November can be drab and dismal, and it may seem that it’s always raining. However, the total precipitation for November is only slightly above the yearly average, and it has the same number of rainy days, on average, as the summer months.  Keep track of rainy/snowy and sunny November days, and see which “wins” this year. Go out and enjoy the first snowfalls!
  • The woods are indeed quiet now, but not silent.  Listen carefully on calm days and you may hear the soft chirps and squeaks, barely audible by humans, of the Common (or Masked) Shrew. They are believed to use echolocation (similar to bats) to navigate and explore objects.  Here’s some great video of the European analog to our Common Shrew.
  • The South Taurid meteor shower (page down), debris shed by Comet 2P/Encke, peaks around Nov. 5, but the waning moon may wash out some.  A conjunction of Mars and Venus will occur the morning of the first, with Jupiter nearby.  The moon pays a visit during the following week.
