Dedicated to all Eucalypt and Bee-lovers.

A recent study by the SA National Biodiversity Institute (Sanbi) in South Africa has found that gum trees provide nectar and pollen for swarms of commercial bees – and bees in turn pollinate about 50 food crops in the country. This “service” bees provide is worth about R10.3 billion a year.

Gum trees are not only important food for bees, but so are many roadside wildflowers, crops, suburban flowering plants and those that many regard as weeds. A major reason for the decline of honey bees around the world is a lack of good forage plants to provide nectar, which is the carbohydrate in the bees’ diet, and pollen the protein. Bees collect nectar from Blue Gum tree blossoms from spring to late summer.

A lack of good quality and variety of forage plants can lead to unhealthy honey bee colonies that are more vulnerable to pests and diseases.

This in turn can lead to insufficient pollination of our important agricultural crop flowers, leading to a decreased yield or quality of the food crop, Insect pollinators are needed for 35 percent of all food production globally – or one of every three bites you eat.

Although most Bluegums have been declared as an invasive species in South Africa, Beekeepers are highly dependent on eucalyptus and if they are all removed because they are aliens it would mean a serious shortage of food for bees – with a knock-on effect on crop pollination.

Because of this, the Department of Environmental Affairs’ legislation on alien and invasive species, updated in 2014, is “nuanced” for eucalyptus trees, not requiring all of them to come under the axe or chainsaw.

Bluegum fantasy

W&N watercolour on Bockingford 300gsm in small sketch-book

Blue gum eucalyptus (Eucalyptus globulus to the botanists), have been a part of the South African landscape since the Gold Rush, long enough that legends have sprung up about how they first made it to the country. The usual story is that 19th Century gold miners encouraged planting of the trees as a quick-growing source of quality lumber, then were disappointed to find out that South African-grown eucs produce wood unsuitable for much besides rough fenceposts and firewood.

The stories have some factual basis: there was a speculative eucalyptus-planting rush in the first years of the 20th Century, with people planning uses from fine furniture to rot-resistant railroad ties. And the home-grown trees, which grew far more quickly than their Australian counterparts, did not turn out to make lousy timber! The logs were extensively used in our mining industry and to this day they are still popular as fence posts and roof timber.

Winter is coming

The first signs of winter are already showing amongst the bluegum trees on our smallholding (Tarlton, Gauteng, South Africa). Yellow grass, fallen leaves and longer shadows accompany me as I take my (now cold) early morning walks. The lizards and snakes have all but disappeared or only come out much later in the day as it warms up. Even the birds seem to be more quiet, preferring to sit in the top branches of some dead trees, basking in the early morning sun and warming up before taking on the day.

This Blue Gum

This blue gum tree greets me every morning as I open my studio curtains. She is always there. She has always been there, for the past ten years. She's the one I sit and stare at when I'm pondering or deep in thought. I've watched her swaying in heavy winds, watched as limbs have broken off and watched as veld fires have swept her base.

She stands across the road from our property, probably about 20m tall and offers a safe haven for all the birds in the area. I've watched as baby crows have fledged from her branches and yet, I've never looked at her properly.

Today I decided to look at her, with new eyes, and paint her.

I think she's wonderful.
