Yes. This is a case of hard data confirming what we already know. As in - few types of butterflies I used to like, and see yearly as a kid - are gone. I see them now once in 5 years, if lucky. I bring my kids to look because it's a first time for them. On the other hand, some types of beetles, ants, flies, mosquitoes, even wasps - are just new. They were not here 20-30 years ago. Now, what are the consequences of all…
This year, I left a portion of my lawn unmowed. I seeded it with a $10 bag of wildflower seeds. It's given me 4 months of beautiful flowers, loads of polinators, many butterflies, and it's given me less yard to mow. I now think that lawns of neatly trimmed grass are about as dumb as it gets.
Not just dumb: as far as biological life goes those trimmed lawns are pretty close to dead useless land.
Now, you don't even need the bags of flower seeds though it helps. Just mow your lawn + remove biomass only twice a year. At max 3, if you've been using fertilizer in the past, or down to 1 if the soil has gotten rid of most nutritients: by cutting grass and removing it you remove nutritients so the fast-growing plants (grasses, nettles, ...) get less of a chance while the slower growing ones (amongst which a lot of wild flowers are, as wel as plants which used to be common before mass-scale agricultuter but are now rare because they don't get a chance mostly due to the abdundance of nitrogen deposition) will florish. For maximum ecological results you'll also leave certain pieces untouched for a year (some butterflies/files/spiders need long grass to survive winter). Do this for a couple of years and your once neatly trimmed green piece of land will turn into an actually valuable piece of colourful nature. I realize this is not for everyone, e.g. it's not an ideal place to play football or teach your kids how to ride their bike, but if you have the chance it's worth giving it a shot.
An ideal tool for applying the above principle is the scythe. It has several advantages over machines like mowers and weedwackers: you learn how to use a nice tool which does not burn fossil fuel, makes no noise except from a satisfying 'swoosh', is relatively cheap yet will likely outlive you. Depending on how you use it it can be a tai-chi-like moment of peace to start the day, or you gan go full-on and treat it as your work-out instead of going to the gym. And in the end it is less work than keeping grass trimmed throughout the growing season (unless you have a robotic mower, or vast amounts of land): mowing/raking for a couple of hours twice a year doesn't even come close to the amount of time I see my neighbours running around with all their mowing devices bi-weekly even though I have more grass to cut than they have.
