Basking Sites
While you might consider a spot on the beach a basking site, many wildlife
species require basking sites a little less exotic. For them, a basking site is
simply a warm sunny spot where they can raise their body temperature before
venturing out for the day.
Unlike mammals, many animal species are unable to control their body
temperatures. These animals are commonly referred to as "cold blooded"
species. This means that their body temperature is controlled by their
surroundings. Such creatures as toads, frogs, turtles, snakes, and insects are
cold blooded. They are most active when the temperatures are warm and move
slower as the temperatures drop in the evening and early morning hours. In
northern climates, these animals hibernate or migrate to avoid the harsh winter
temperatures.
Basking sites do not need to be elaborate. In the garden, the basking site
can be a few rocks that warm quickly in the morning sun. In addition to
providing a spot for animals to warm their bodies, a small pile of rocks also
can provide shelter from predators. In a garden pond, a rock or a log can
provide a basking site for frogs and turtles.
Butterflies, as well as insects, are cold blooded and move very slowly when
the temperatures are low. Butterflies tend to be active on sunny days and
inactive when it is cloudy. In the early morning and on cool days, butterflies
often can be seen with their wings open soaking up the heat. They must increase
their body temperature before they are capable of strong flight. A light-colored
rock or garden ornament placed to catch the early morning sun, can be used as a
site for butterflies to perch on while waiting for their body temperatures to
rise.
In addition to serving as basking sites, rocks, old logs, and small brush
piles can benefit other wildlife. Rocks and logs placed in shade can provide
relief and shelter from the mid-day heat of summer. Many species also seek
winter shelter in rock piles, old logs, and brush piles. The common Ladybug
Beetle is one insect that will congregate by the thousands under rocks, bark,
and even leaves to overwinter in northern climates.
When planning your backyard habitat, be sure to include basking sites. Rocks
and logs not only provide needed habitat for wildlife, but can be used to create
interest and diversity of texture in the garden.
