As my other litter question stated, I live on a semi-rural road, and about twice a year pick up litter from the verge. Others pick up litter too, but there are swathes of floodplain land, conservation land, as yet undeveloped land, two houses owned by very old people....The result is that I do most of the litter pick-up, both sides, for about 1.5 miles.
It's a lot. So far, I don't have to be selective about what I pick up, but if I do, what should my priorities be, from the point of view of the wildlife in the area?
Number one priority in terms of wildlife is six-pack plastic webbing. After that, plastic bags which are number one in terms of unsightliness. And after these two items -- plastic bottles, glass bottles, broken glass, foam cups, some old styrofoam (it's being phased out in our area), plastic food containers, metal cans, occasional auto parts, cardboard, paper and occasional unidentified stuff. That's it. Is there anything it would be better to leave? For example, is the one old tire in the middle of brambles useful habitat for some critter?
Edit in Response to Comments:
(1) Restricting the list of litter: I've given a complete list above. Aside from the one old tire I mentioned, there is nothing I cannot pick up easily with one hand.
(2) Wildlife: Deer, foxes, (and reputedly coyotes), and all the small furry animals from raccoons down to voles. A variety of snakes and amphibians. Also birds.
