The Tunguska event of 2015 – OK, more tree clearing by the ZESA lines

So someone had the idea to run the electricity lines up the bottom of a small inclined valley. Then various trees grew along the valley and up the valley sides. The consequence over time is that the trees along the valley and up the sides have grown up higher than the electricity lines in the valley floor.

Now was the time to recreate the Tunguska event of 1908 in Siberian Russia whereby 2000km2 of forest (80 million trees) were destroyed by the mid-air explosion of a meteor, with no known casualties.

We had to remove all tree that were in danger of being blown onto the power lines. Many were already dead and represented a clear risk as they weakened over time. Some dead pines were already leaning in the wrong direction.

Naturally our efforts to remove the tree should not bring down the power lines. Hence the use of the 6 ton pulley/winch to direct the fall.

Tree clearing the ZESA and fencing line

The challenge is two fold and based on the geography.

 

First: the electricity line up from Troutbeck  enters Hornbydale running through the bottom of a small valley. Along the valley sides pine, wattle and gum trees have grown over the last 20 Р30 years. Now they tower over the electricity (ZESA) lines and we are carefully removing them on both sides. The direction of the prevailing wind is of course just right to blow weaker trees onto the line.

Second: some of the same trees are poised to fall right over the line of our new fence – and that would never do!

The picture below sums up these two challenges pretty well…
