When it rains every day for months, the trees start closing in
around our house in Fish Bay. We left most of the native trees on the property,
and planted Arica palms and bougainvillea in the yard. When they all get bushy they
block the path and the view. Definitely time to sharpen up the machete and get
out the clippers.
Sometimes I feel a little badly about chopping back the
native trees, but most of them don’t seem to mind a trim. The invasive trees I
wish would disappear, like the false tamarinds, often grow back even more
aggressively no matter how much I cut them.
In the article, Pollan reported that the claims about plants
having feelings have not been substantiated. However some scientists have documented
plant behaviors that “look very much like learning, memory, decision-making and
intelligence” as plants respond to a wide variety of information about their
environment – including available levels of light, water, and nutrients, as
well as temperature and soil conditions.
Even in the 1880s, Darwin’s research led him to believe that
there was a type of intelligence in the root tips of plants that allowed them to
process sensory information and in that way adapt to their environment.
More recent studies have shown that plants also communicate through
chemical and electrical signals, and even share and information through widespread
underground webs of fungi. Although most scientists do not conclude from this information
that trees are ‘conscious’, it does seem that they may actually be ‘intelligent’
even though they do not have brains.
In fact, the lack of a brain may make plants more resilient to the impacts of environmental changes and destructive events. They can lose up to 90 percent of their mass and still survive and grow back. (Plus they can make their own food from sunlight and water.)
Rather than viewing plants as insensate, lower life forms, Pollan
suggests that their way of adapting to the world could provide a model for our
own future, one that is “organized around systems and technologies that are
networked, decentralized, modular…and green, able to nourish themselves on
light”.
It’s interesting to think about what we could learn from the
trees about survival skills – especially the trees that are well-adapted to
island life. In the short term I am still planning to cut back the trees in my
way, knowing they can manage okay with a few less branches. I’m sure some of
them will still be going strong long after I am gone.
