The natural Navigation: The Right Course, Naturally

Natural navigation is at its most fun when it is a puzzle and a test of our senses. Have a look at this photo and get ready to test your powers of observation.

This is a photo of a monkey puzzle tree that I have been growing in our greenhouse since early this year. I have taken it out of the greenhouse for better light for this photo. Greenhouses are great places to study the effect of sunlight on plant growth because all the wind effects are cancelled.

Now see if you can tell in which direction this photo was taken. Are we looking north, south, east or west?

Answer time…

In this photo we are looking west. The monkey puzzle tree has grown towards the southern light to the left, an effect known as ‘phototropism’.

‘That’s easy!’ I hear some of you cry, but I did warn you that…

Trees are the easiest plants to read to find direction, but one of my chilli plants is also doing a fine job. It has been growing in a greenhouse and so shows only the effects of the sun and no combing from the wind. It could not be much clearer.

The plant is dramatically heavier on its southern side and it is also displaying the ‘Tick Effect’ across its stems – more vertical growth on the northern side, more horizontal on the southern.

Just back from minus 15 degrees in the Scottish Highlands and the unseasonable season continues! It’ s great – even if it has cost me a Land Rover Defender (AXA have just left a message to say that mine is a write-off following a failed negotiation with a stout beech tree).

Here I am taking a break from family duties and checking that the snow is doing what I have come to expect of it. The compass feels very light after hours of hauling a tobogganing sled, weighed down by two lumps, up the hill repeatedly.

I have found myself at airports a lot recently and it occurred to me that there is not very much to inspire those interested in nature about them in general. It does sometimes take a bit of lateral thinking to spot the clues in places like that.

Some man-made structures can give us a clue to help us on our way until nature comes to our aid again. Churches are a good example. A lot of churches are aligned East-West and this can offer a short term hand if all else is proving confusing, not unusual in a built-up area. The problem with a lot of artificial clues like this though is that they are very short-lived, they offer a clue for a few seconds or minutes at best, but then disappear out of sight and leave the navigator on their own again. Airports, with a little lateral and…
