Back when I was a kid, after a heavy downpour the roads would be crowded with earthworms. You really had to watch where you step to avoid stepping on one of those suckers. Fast forward today and I RARELY see a single worm out on the road after a similar downpour.

How were you a kid?

I think I noticed this too. When I was in elementary school in the early 2000s, the stench of run-over worms was almost unbearable after rains. Worm guts everywhere. There were also bugs flying around me whenever I went outside to play. I hated it and wanted it to go away.

It did.

Probably a result of tiling the soil. Disturbing the natural ecosystem of it. And pesticides too presumably. Something like permaculture could help. Chop and drop. Mulching on the spot.

True only if tilling has increased recently. The question is, what has changed since the last time the dead fields had earthworms? That's the cause. Reversing or neutralizing that change is the cure. Let's figure out how to fix this the right way, and now , before the remaining fields die off too.

It's not clear that this is a recent phenom. It's a result of voluntary samples, that cant be compared to a previous situation. It may be useful if they repeat the measurements in the same places, but currently it's more like an internet pool.

Any link to the actual study? Potential pitfalls of this kind of study:

- is the historical data available?

- is the decrease significant?

- is the sample size sufficient?

- is the sampling method reliable? (and conducted in the same conditions as the previous data points?)

- is there a difference between cultivated fields and uncultivated fields?

- is there any correlation between cultivation types and worm presence (not just usage of pesticides, but also types of cultures?)

- are there differences in soil properties (minerals, etc...)

etc...

I'd really like to have reporters link to the actual paper, or even better, datasets, in this time and age.

Does it concern you? It does me.

Oh yeah. Be careful with what you wish for. One day us humans might not be just dominant, we will be alone. And in that sense, I don't want us to prevail against Mother Nature; I just want a healthy balance.

This reminds me of a passage in the book Sapiens, where the author muses that there may have been prehistoric tribes where grandparents told tales of when mammoths were so plentiful hunters would take them every month, and the grandchildren would smile and nod. The grandchildren would in turn grow up and tell their grandchildren that there were once beasts called mammoths, and these grandchildren too would smile and nod...

I was out digging in my field yesterday (in Ireland, not England) and thought it was interesting that there was a large variance in worm counts. Some areas had massive numbers of worms pushing 20cm, and others had relatively few, smaller ones. The bigger worms were in areas that hadn't been grazed by sheep, but I'm not sure how that relates, if at all (the sheep have been gone for a few years).
